The subject matter described in this application is related to subject matter disclosed in the following applications: U. Application Ser. This patent document pertains generally to network systems and more particularly, but not by way of limitation, to an inflatable air mattress system architecture. In various examples, an air mattress control system allows a user to adjust the firmness or position of an air mattress bed.
The mattress may have more than one zone thereby allowing a left and right side of the mattress to be adjusted to different firmness levels. Additionally, the bed may be adjustable to different positions.
For example, the head section of the bed may be raised up while the foot section of the bed stays in place. In various examples, two separate remote controls are used to adjust the position and firmness, respectively. Some embodiments are illustrated by way of example and not limitation in the figures of the accompanying drawings in which:.
System 10 can include bed 12 , which can comprise at least one air chamber 14 surrounded by a resilient border 16 and encapsulated by bed ticking The resilient border 16 can comprise any suitable material, such as foam. As illustrated in FIG. First and second air chambers 14 A and 14 B can be in fluid communication with pump Pump 20 can be in electrical communication with a remote control 22 via control box Remote control 22 can communicate via wired or wireless means with control box Control box 24 can be configured to operate pump 20 to cause increases and decreases in the fluid pressure of first and second air chambers 14 A and 14 B based upon commands input by a user through remote control Remote control 22 can include display 26 , output selecting means 28 , pressure increase button 29 , and pressure decrease button Output selecting means 28 can allow the user to switch the pump output between the first and second air chambers 14 A and 14 B, thus enabling control of multiple air chambers with a single remote control For example, output selecting means may by a physical control e.
Alternatively, separate remote control units can be provided for each air chamber and may each include the ability to control multiple air chambers. Pressure increase and decrease buttons 29 and 30 can allow a user to increase or decrease the pressure, respectively, in the air chamber selected with the output selecting means Adjusting the pressure within the selected air chamber can cause a corresponding adjustment to the firmness of the air chamber.
As shown in FIG. Switching means 38 can be, for example, a relay or a solid state switch. Switching means 38 can be located in the pump 20 rather than the control box Pump 20 and remote control 22 can be in two-way communication with the control box Pump 20 can include a motor 42 , a pump manifold 43 , a relief valve 44 , a first control valve 45 A, a second control valve 45 B, and a pressure transducer 46 , and can be fluidly connected with the first air chamber 14 A and the second air chamber 14 B via a first tube 48 A and a second tube 48 B, respectively.
First and second control valves 45 A and 45 B can be controlled by switching means 38 , and can be operable to regulate the flow of fluid between pump 20 and first and second air chambers 14 A and 14 B, respectively. In an example, pump 20 and control box 24 can be provided and packaged as a single unit. Alternatively, pump 20 and control box 24 can be provided as physically separate units.
In operation, power supply 34 can receive power, such as VAC power, from an external source and can convert the power to various forms required by certain components of the air bed system Processor 36 can be used to control various logic sequences associated with operation of the air bed system 10 , as will be discussed in further detail below. The example of the air bed system 10 shown in FIG. However, other examples may include an air bed system having two or more air chambers and one or more pumps incorporated into the air bed system to control the air chambers.
In an example, a separate pump may be associated with each air chamber of the air bed system or a pump may be associated with multiple chambers of the air bed system. Separate pumps may allow each air chamber to be inflated or deflated independently and simultaneously. Furthermore, additional pressure transducers may also be incorporated into the air bed system such that, for example, a separate pressure transducer may be associated with each air chamber.
In the event that the processor 36 sends a decrease pressure command to one of air chambers 14 A or 14 B, switching means 38 can be used to convert the low voltage command signals sent by processor 36 to higher operating voltages sufficient to operate relief valve 44 of pump 20 and open control valves 45 A or 45 B. Opening relief valve 44 can allow air to escape from air chamber 14 A or 14 B through the respective air tube 48 A or 48 B. Processor 36 may send the digital signal to remote control 22 to update display 26 on the remote control in order to convey the pressure information to the user.
In the event that processor 36 sends an increase pressure command, pump motor 42 can be energized, sending air to the designated air chamber through air tube 48 A or 48 B via electronically operating corresponding valve 45 A or 45 B.
While air is being delivered to the designated air chamber in order to increase the firmness of the chamber, pressure transducer 46 can sense pressure within pump manifold Processor 36 can send the digital signal to remote control 22 to update display 26 on the remote control in order to convey the pressure information to the user.
Generally speaking, during an inflation or deflation process, the pressure sensed within pump manifold 43 provides an approximation of the pressure within the air chamber. An example method of obtaining a pump manifold pressure reading that is substantially equivalent to the actual pressure within an air chamber is to turn off pump 20 , allow the pressure within the air chamber 14 A or 14 B and pump manifold 43 to equalize, and then sense the pressure within pump manifold 43 with pressure transducer Thus, providing a sufficient amount of time to allow the pressures within pump manifold 43 and chamber 14 A or 14 B to equalize may result in pressure readings that are accurate approximations of the actual pressure within air chamber 14 A or 14 B.
In an example, another method of obtaining a pump manifold pressure reading that is substantially equivalent to the actual pressure within an air chamber is through the use of a pressure adjustment algorithm. In general, the method can function by approximating the air chamber pressure based upon a mathematical relationship between the air chamber pressure and the pressure measured within pump manifold 43 during both an inflation cycle and a deflation cycle , thereby eliminating the need to turn off pump 20 in order to obtain a substantially accurate approximation of the air chamber pressure.
As a result, a desired pressure setpoint within air chamber 14 A or 14 B can be achieved without the need for turning pump 20 off to allow the pressures to equalize. The latter method of approximating an air chamber pressure using mathematical relationships between the air chamber pressure and the pump manifold pressure is described in detail in U.
Architecture includes bed , central controller , firmness controller , articulation controller , temperature controller , external network device , remote controllers , , and voice controller While described as using an air bed, the system architecture may also be used with other types of beds.
Thus, in various examples, central controller acts a relay between the various components. In other examples, different topologies may be used. For example, the components and central controller may be configured as a mesh network in which each component may communicate with one or all of the other components directly, bypassing central controller In various examples, a combination of topologies may be used.
For example, remote controller may communicate directly to temperature controller but also relay the communication to central controller In yet another example, central controller listens to communications e.
For example, consider a user sending a command using remote to temperature controller Central controller may listen for the command and check to determine if instructions are stored at central controller to override the command e.
Central controller may also log the command for future use e. In various examples, the controllers and devices illustrated in FIG. The storage device may include volatile or non-volatile static storage e. The storage device may store instructions which, when executed by the processor, configure the processor to perform the functionality described herein. For example, a processor of firmness control may be configured to send a command to a relief valve to decrease the pressure in a bed.
In various examples, the network interface of the components may be configured to transmit and receive communications in a variety of wired and wireless protocols. For example, the network interface may be configured to use the The previous list is not intended to exhaustive and other protocols may be used. Not all components of FIG. For example, remote control may communicate with central controller via Bluetooth while temperature controller and articulation controller are connected to central controller using Within FIG.
Moreover, in various examples, the processor, storage device, and network interface of a component may be located in different locations than various elements used to effect a command.
For example, as in FIG. Similar separation of elements may be employed for the other controllers and devices in FIG. In various examples, firmness controller is configured to regulate pressure in an air mattress. For example, firmness controller may include a pump such as described with reference to FIG. Thus, in an example, firmness controller may be respond to commands to increase or decrease pressure in the air mattress.
The commands may be received from another component or based on stored application instruction that are part of firmness controller Thus, in an example, the processor of central controller and firmness control may be the same processor. Furthermore, the pump may also be part of central controller Accordingly, central controller may be responsible for pressure regulation as well as other functionality as described in further portions of this disclosure.
In various examples, articulation controller is configured to adjust the position of a bed e. In an example, separate positions may be set for two different beds e. The foundation may include more than one zone that may be independently adjusted.
Articulation control may also be configured to provide different levels of massage to a person on the bed. In various examples, temperature controller is configured to increase, decrease, or maintain the temperature of a user. For example, a pad may be placed on top of or be part of the air mattress.
Air may be pushed through the pad and vented to cool off a user of the bed. Conversely, the pad may include a heating element that may be used to keep the user warm. In various examples, temperature controller receives temperature readings from the pad.
In various examples, additional controllers may communicate with central controller These controllers may include, but are not limited to, illumination controllers for turning on and off light elements placed on and around the bed and outlet controllers for controlling power to one or more power outlets. In various examples, external network device , remote controllers , and voice controller may be used to input commands e. The commands may be transmitted from one of the controllers , , or and received in central controller Central controller may process the command to determine the appropriate component to route the received command.
For example, each command sent via one of controllers , , or may include a header or other metadata that indicates which component the command is for. Central controller may then transmit the command via central controller 's network interface to the appropriate component. For example, a user may input a desired temperature for the user's bed into remote control The desired temperature may be encapsulated in a command data structure that includes the temperature as well as identifies temperature controller as the desired component to be controlled.
The command data structure may then be transmitted via Bluetooth to central controller In various examples, the command data structure is encrypted before being transmitted. Central controller may parse the command data structure and relay the command to temperature controller using a PAN. Temperature controller may be then configure its elements to increase or decrease the temperature of the pad depending on the temperature originally input into remote control In various examples, data may be transmitted from a component back to one or more of the remote controls.
For example, the current temperature as determined by a sensor element of temperature controller , the pressure of the bed, the current position of the foundation or other information may be transmitted to central controller Central controller may then transmit the received information and transmit it to remote control where it may be displayed to the user.
In various examples, multiple types of devices may be used to input commands to control the components of architecture For example, remote control may be a mobile device such as a smart phone or tablet computer running an application. Other examples of remote control may include a dedicated device for interacting with the components described herein.
There are some codec and frame control settings that trigger the adding of pulldown to In my initial testing, a default? It was a few pixels on each side It may be that my defaults were not typical Conforming 25 to I'm just a little suspicious of doing it in Compressor, because Apple hasn't mentioned that it is an option in Compressor 3. Dave, Compressor cannot add Conforming from 25 to You point is well taken, however I was only making a specific comment about 25 to Sorry, Jeff, I must disagree with you on this point from a bit of research and testing, which shows that it does seem to work properly.
I will present my findings in a separate post. However, I never state anything with absolute certainty When this topic came up a couple of weeks ago, and now again, I decided to check out some of the available options for adding pulldown via software.
After Effects can also add pulldown, as well. They all seem to do the job just fine. For now, I'll focus just on Compressor, as it is the "big unknown. Plus, since it's bundled with Final Cut Studio, Compressor costs nothing extra. I should state that I didn't discover this method, and was quite surprised as well to find out that Compressor seems to be able to add pulldown to I couldn't find any mention of Compressor and adding pulldown in the Compressor manual or elsewhere in Apple's support pages on their website.
According to the forum posts, earlier versions of Compressor may be able to add pulldown, as well as version 3. In a nutshell, here are the key steps to get this to work: - You would typically choose a Compressor preset "setting" to work with and have the input and output video codecs be the same since we're are just concerned with adding pulldown.
In other words, start with a preset and customize it. Note: I have not tried changing any of the other Frame Controls settings, such as Rate Conversion, to see if that affects the output The settings mentioned above seem to result in proper pulldown being added.
Compressor also seems to work well in removing pulldown that it has added. However, when removing pulldown with Compressor, its scene detection and broken cadence detection may not work well if you choose "Allow Job Segmenting" in the Encoder tab in the Inspector window.
In any event, I would suggest you run your own tests to make sure things are working properly. Plus, Compressor isn't the fastest horse in the race. However, you need to be very careful about selecting the proper settings or you may get other, unexpected changes to your video cropping, frame resizing, etc. At least, for me, choosing the proper settings was a bit tricky. Good stuff. I'd like to try this method with one change.
Not add fields on output, as we do a lot of stuff for web, and it makes no sense to add fields to progressive input HD; regardless if it is scaled down on final output.
