摘要： A method and an ambient light color sensor adapted to determine color of ambient light comprising a memory, a processor, and a light color sensor with a plurality of channels that detect light at different wavelengths. Wherein the memory comprises a calibration matrix determined by calibrating a test light color sensing device under at least one ambient lighting condition, and a normalized gain value for each channel determined by calibrating the ambient light color sensing device to an artificial light source. Wherein the processor receives the sensor readings from the light color sensor, normalizes each received sensor reading using the normalized gain value of a respective channel, determines at least one measured light color value that quantifies color of light from the normalized sensor readings, and determines at least one calibrated light color value by correlating the at least one measured light color value through the calibration matrix.

摘要： An innovative system for transmitting encrypted 1-bit audio over an Ethernet network comprises using an omni-directional micro-electrical-mechanical system acoustic sensor element (11) to provide an analog input signal (33) to a sigma-delta modulator (12) which then creates a pulse density modulated 1-bit data stream (32), at an audio oversampling rate, to a first input of a first exclusive-or (XOR) logic gate (58). The second input of the XOR logic gate is simultaneously presented with a first pseudo-random 1-bit data stream (78), at the same audio oversampling rate, thereby resulting in an encrypted pulse density modulated (PDM) 1-bit data stream (73) at the output of the XOR logic gate. The encrypted PDM 1-bit data stream is clocked into a first-in first-out (FIFO) memory at the audio oversampling rate and is clocked out of the first FIFO memory as Ethernet PDM frame data packages (74) at a predetermined Ethernet PHY transfer rate.

摘要： An apparatus cools electronic circuitry. An enclosure surrounds the electronic circuitry and has plural surfaces. Air intake holes are disposed in at least one surface and face at least one first direction. Air exhaust holes are disposed in at least another surface and face at least one second direction different than the first direction. A heat sink is in thermal contact with the circuitry and conducts heat generated by the circuitry. When a fan operates, air is drawn from an exterior of the enclosure through the air intake holes, absorbs heat from the heat sink, and then is directed through the air exhaust holes into the exterior of the enclosure. The heat sink is further in thermal contact with the enclosure so that when the fan does not operate, heat is drawn from the circuitry to the enclosure via the heat sink and is dissipated from the exterior.

摘要： A roller shade adapted to adjustably cover a structural opening comprising a pair of longitudinal side panel assemblies each comprising a tensioning assembly and adapted to be attached at opposite sides of the structural opening and a roller tube assembly adapted to be attached to and between the pair of longitudinal side panel assemblies. The roller tube assembly comprises a roller tube comprising at least one channel and a shade material attached to the roller tube and adapted to unroll from the roller tube from an opened position to a closed position. The roller tube assembly further comprises at least one cable cone secured to an end of the roller tube and comprising a lateral wall comprising a plurality of index slots disposed at radial intervals along the lateral wall. The roller shade also comprises at least one cable adapted to be wound about the cable cone, be tensioned by the tensioning assembly, and be attached to a free end of the shade material. The cable cone is adapted to be aligned with respect to the roller tube to an aligned position at which one of the index slots is substantially aligned with the at least one channel in the roller tube. An index insert is adapted to be inserted through the substantially aligned index slot and into the channel in the roller tube to lock the alignment between the roller tube and the cable cone.
