Abstract: A method and apparatus filter light spectrum. Ambient light conditions of light that is ambient to a user device can be sensed. Ambient light color conditions can be determined based on the sensed ambient light conditions. User device charging times when the user device is being charged can be monitored. User device motion including movement of the user device can be monitored. User device activity can be monitored. Color-modified image display times can be ascertained from at least one selected from the user device motion, the user device activity, and the user device charging times. A color-modified image can be generated based on at least the ambient light color conditions and the color-modified image display times. The color-modified image can be displayed.

Abstract: An alternating current (AC) powered self organizing wireless node (100, 400, 600) includes a self organizing wireless receiver-transmitter (115), an AC branch connection (105), an AC to direct current (DC) converter (110), a secondary power function (120), and a housing (150). The self organizing wireless receiver-transmitter can communicate information throughout a network of compatible self organizing nodes solely using radio transmission to and reception from nearby self-organizing nodes. The secondary power function can couple power to the AC to DC converter for powering the self organizing wireless receiver-transmitter when AC power is not provided. The AC powered self organizing wireless node is designed and fabricated for agency certification. The AC powered self organizing wireless node may include one or more sensors (125), sensor inputs (135), transducers (130), or control outputs (155).

Abstract: Battery life and cooling are improved in an electronic device. A thermoelectric module and phase change material module are placed near a heat source in an electronic device. The thermoelectric module and phase change material module insulate a surface to be cooled on the electronic device. The thermoelectric module generates an electrical current in response to a temperature differential at opposite surfaces on the thermoelectric module. The phase change material module enhances or limits the temperature differential seen at the thermoelectric module. The electrical current generated by the thermoelectric module is used to charge a battery of the electronic device.

Abstract: The present invention provides an apparatus (200) that includes a heat-generating component (202) and a heat-dissipating apparatus (120). The heat-generating component (202) is mounted on a substrate (204). The heat-dissipating apparatus (120) includes a housing piece (100) that includes a sealed chamber (102) and a phase change material (106) disposed within the sealed chamber (102). The heat-dissipating apparatus (120) is thermally coupled to the heat-generating component (202) and provides for heat dissipation by an endothermic process of changing phase from solid to liquid, thereby lowering the operating temperature of the heat-generating component (202).
