Abstract: A bed has a mattress. A first wireless charging array is positioned on a top side of the mattress nearer a head of the mattress. A pillow is configured to be positioned atop the first wireless charging array. The pillow includes a second wireless charging array located on an underside of a pillow. The second wireless charging array is configured to receive energy from the first wireless charging array. A companion device is configured to use the energy. An energy storage device is within the pillow. The energy storage device is configured to store charge received by the first wireless charging array. The energy storage device is configured to supply power to the companion device.

Abstract: A damper controller may be configured to send damper control commands to open and close an outdoor air damper to provide free cooling as necessary to satisfy a temperature setpoint inside the building. In some cases, the damper controller may initiate a damper fault test to determine if a damper fault is present. The damper fault test may be based, at least in part, on an outdoor air temperature input, a discharge air temperature input, a commanded damper position, and a damper fault temperature threshold. If a damper fault is determined, the damper controller may send an alert indicative of a detected damper fault. In some cases, the damper fault test results may be weighted to reduce the false positives alerts.

A check may be made for sensors connected to the controller. The control type of the sensors may be determined. The menu structure may be repopulated based on the control type. The user interface may then be updated. This approach may be repeated as needed.

Abstract: A device having a display and a user interface incorporating buttons, switches or keys that may be programmable for various functions related to the purpose of the device and its display. The keys may be programmed for virtually any functions available to or on the device. Also, some or all of the keys may be reprogrammed for other or new functions. The device may be programmed by the user with the keys on the device to obtain a custom design having functions assigned to the keys according to a particular design, desire or choice of the user. The keys may be situated on an area having touch sensitive technology such that touching a particular key will call forth a function that is assigned to the key. The keys may be in a touch sensitive area apart from the display or be fully or in partly on a touch sensitive display.

Abstract: A system having a mixed air box with inputs of return air from a space or spaces of a building, and of outside air. The mixed air box may have an output of discharge air to the space or spaces of the building. The air from the output may be return air that is conditioned with cooling, heat, or outside air. A damper may be situated at the input of outside air to the mixed air box. A temperature sensor may be positioned at the input for outside air and at the output of discharge air. A cooling mechanism may be at the output of the discharge air. The temperature sensor may be downstream from the cooling mechanism. An economizer may have connections with the damper, the temperature sensor and the cooling mechanism.

Abstract: A system and approach that may provide power to network switches of controllers in a failsafe manner. For instance, when a controller is receiving normal power, the controller may act as a power over Ethernet (POE) source that supplies power to its connected Ethernet devices as required. However, if power to a controller is lost, then Ethernet devices may switch to a powered device mode and use power from a neighboring device to keep active. Some power may be tapped for network switch operation from any network switch port receiving power from another device. This may allow communication to remain operational across multiple devices in a string of which some have lost a source of normal power.

Abstract: An economizer controller with sensor calibration. A controller sensor may be used to measure a parameter. At the same time at the same location of the measurement with the controller sensor, a measurement of the same parameter may be made with a precision sensor. The difference between the two measurements may be saved to a controller memory as an offset. The offset may be used to compensate future measurements of the same parameter by the controller sensor. Additional offsets at various magnitudes may be obtained between the precision and the controller sensors for compensating subsequent measurements by the controller sensor. Measurements with the compensated sensor may be used for calibrating sensors in other economizer controllers, for example, at remote locations in the field.
