  • Publication number: 20210345521
    Abstract: 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.

  • Publication number: 20210344181
    Abstract: An integrated latching mechanism includes a slider button extending along a first direction, curved elastic arms that extend from the slider button in a second direction and then curve back in an direction opposite thereto, a locking part contiguous with the slider button and extending away from the slider button and the elastic arms in a third direction perpendicular to the first direction. In response to ends of the elastic arms being held at fixed positions and an external force urging the slider button in a direction opposite to the third direction, the locking part moves in the same direction, and the urging of the slider button distorts the elastic arms such that upon removal of the external force, the elastic arms move the slider button and the locking part in the third direction. The elastic arms, slider button, and locking part form a single piece of elastic material.

  • Publication number: 20210320907
    Abstract: 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.
