Abstract: A communications cable is provided that includes a pair of twisted pair of wires, each coated with a fluoropolymer insulator. The twisted pair of wires is configured to carry a differential signal, such as a differential data signal and/or a differential power signal. The fluoropolymers are highly effective insulators and significantly reduce both the effects of internal and external electromagnetic interference while maintaining low cable attenuation, even when operating within a temperature range of −40° C. to 150° C.

Abstract: A control system for a HVAC system for a structure and including a blower that flows air over an indoor heat exchanger. The control system may include a first input device, a first sensor, and a processor in electronic communication with the first input device, the first sensor, and the blower of the HVAC system. The first input device may be operable to accept a zoning mode selection. The first sensor may be sensor operable to measure a first temperature at a first location within the structure. The processor may be programmed to determine a cooling or heating demand on the HVAC system based on an input temperature and the first measured temperature. The processor may be further programmed to adjust an air flow rate produced by the blower based on the demand on the HVAC system and the zoning mode selection.

Abstract: The disclosure provides, for example, an optical coherence tomography device capable of performing tomographic imaging over a wide area at a time and of performing tomographic imaging of a distant object. The optical coherence tomography device includes an objective lens configured to focus light emitted from a light source onto a sample. The optical coherence tomography device is configured to perform tomographic imaging of the sample based on interference between sample light, which is reflected light from the sample, and reference light, which is reflected light from a reference surface provided between the objective lens and the sample. The sample light and the reference light each are to pass through the objective lens. The light emitted from the light source and passed through the objective lens is to illuminate the sample at a wide angle. The reference surface includes a light scatterer.

Abstract: An air conditioner includes an outdoor unit including a first heat exchanger and an indoor unit including a second heat exchanger. The first heat exchanger includes a first heat transfer tube and a plurality of first fins. The second heat exchanger includes a second heat transfer tube and a plurality of second fins. The first heat transfer tube, the first fins, the second heat transfer tube, and the second fins are made of aluminum or an aluminum alloy. A first sacrificial layer is provided on a surface of the first heat transfer tube. The first sacrificial layer is lower in potential than a base material of the first heat transfer tube and lower in potential than the first fins. A fin pitch of the first fins is larger than a fin pitch of the second fins.
