Abstract: A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required.

Abstract: The present invention discloses a biological detection device and a detecting method. The biological detection device comprises a substrate, an electric field unit, a liquid crystal/polymer composite film (LCPCF), a power supply, a processing unit, and an image sensor. Because of the electrically tunable orientations of the liquid crystal (LC) director anchored among the polymer grains, the wettability of the LCPCF changes with an applied electric field.

The change of contact angle of blood on LCPCF and the blood droplet motion on LCPCF indicate the concentration of TG and the concentration of HDL.

Abstract: The present disclosure is directed at methods, apparatuses, and techniques for detecting an acoustic event along a channel. Different wavelengths of an optical signal are multiplexed along a fiber optic strand extending along the channel. The strand has groups of transducers located along its length, and all of the transducers in any one of the groups reflect a tuned wavelength when not under strain. The wavelength that the transducers reflect changes in response to strain. Optical signal processing equipment receives reflected optical signals from the groups of transducers, and determines, for each of the groups of transducers, differences between wavelengths of the optical signals reflected by the transducers of that group and the tuned wavelength for that group. The differences correspond to the loudness of the event measured by that group of transducers, which can then be graphically represented to a person for analysis.
