Title: Decoder for variable-number of channel presentation of multidimensional sound fields
Inventor: MARK FRANKLIN DAVIS
IPC: H04H20/88
Filed: 1992-01-08
Granted: 1999-11-01
Abstract: The invention relates to the reproduction of high-fidelity multi-dimensional sound fields intended for human hearing. More particularly, the invention relates to the decoding of signals representing such sound fields delivered by one or more delivery channels, but played back over a number of presentation channels which may differ from the number of delivery channels. In one embodiment, a subband decoder combines spectral information in the frequency domain prior to inverse filtering, thereby incurring implementation costs roughly proportional to the number of presentation channels rather than to the number of delivery channels.

Date Mar. 5, 1992.A sensor (1) is provided for sensing the entrainment of a fluid of low specific gravity in a fluid of higher specific gravity, particularly the entrainment of refrigerant gas in refrigerant liquid. The sensor (1) is typically installed into a higher pressure liquid supply line (24) of a refrigeration system (26). The sensor (1) has a differential float (16) including a float member (54) pivoted about a pivot (56) in a chamber (14) coupled to the supply line (24). The float member (54) has a specific gravity greater than the specific gravity of both of the fluids in which it operates. However, the location of the pivot (56) intermediate of the length of the float member (54) gives a net specific gravity for the differential float (16) which is less than the specific gravity of one of the fluids. Hence, the differential float (16) can withstand a high pressure operation, say at 2MPa, and can operate as a float for detecting the presence or absence of the fluid of lower specific gravity in the fluid of high specific gravity. The differential float (16) can also be used as gauge snubber (20) or to replace refrigerant capillary control tubes.
