摘要： A system for detecting leaks on a surface, such as a floor or a bottom of an equipment cabinet, includes a sound wave generator configured to generate sound waves, a tube having a first end coupled to the sound wave generator, a second end opposite the first end, and a plurality of openings formed in the tube, and a sound wave receiver coupled to the second end of the tube. The sound wave receiver is configured to detect sound waves generated by the sound wave generator that travel through the tube. The arrangement is such that sound waves are blocked from detection by the sound wave receiver when fluid enters the tube through the plurality of openings in the tube thereby indicating a fluid leak on the surface.

摘要： An air pressure differential sensing system includes a conduit defining an air passage through which air flows upon application of an air pressure differential across different regions of the air passage, a flap pivotally connected to the conduit, and a sensing device mounted proximate to the air passage and separate from the flap. The flap is configured to move about a pivotal axis in response to the air flowing through the air passage. The sensing device is configured to sense an angular position of the flap about the pivotal axis, the angular position of the flap being a function of the air pressure differential.

摘要： A bi-directional differential bus interface that includes a differential transmitter having a non-inverting terminal and an inverting terminal, a differential receiver having a non-inverting terminal and an inverting terminal, and a biasing circuit that is electrically coupled to the non-inverting terminal of the differential transmitter and the inverting terminal of the differential transmitter. The biasing circuit is configured to generate a voltage between the non-inverting terminal of the differential transmitter and the inverting terminal of the differential transmitter that is approximately 200 mV or more in response to assertion of a control signal received on a control input of the biasing circuit.
