Filed: 1991-09-05
Abstract: An automotive voltage regulator is disclosed to have plural regulated outputs using a transient protected isolator output stage (TPIOS) that prevents a system fault condition on any one output from adversely affecting the other outputs. In an automotive environment employing a nominal 14-volt supply, an individual output can be taken fron -4 to +26 volts without causing damage or having any significant reaction on the non-faulted outputs. The circuit employs a relatively small NPN output pass transistor and, therefore, requires a relatively low value stabilizing bypass capacitor.

Abstract: A method is disclosed for forming thin, suspended membranes of epitaxial silicon material. Silicon oxide strips (12) having a predetermined thickness are first formed on a silicon substrate (10). A gap (14) provided between adjacent pairs of strips (12) is preferably less than or equal to about 1.4 times the thickness of the silicon oxide strips (12). The underlying silicon substrate (10) is exposed within these gaps (14) in the silicon oxide layer, whereby the gaps (14) provide seed holes for subsequent epitaxial growth from the silicon substrate (10). Epitaxial silicon is grown through the gaps (14) and then allowed to grow laterally over the silicon oxide strips (12) to form a continuous layer (20) of epitaxial silicon over the silicon oxide strips (12). The backside of the silicon substrate (10), i.e., the surface opposite the surface having the silicon oxide strips (12), is then masked to delineate the desired diaphragm and microbridge pattern. The silicon is etched conventionally from the backside of the silicon substrate (10). Etching is terminated substantially automatically by the presence of the silicon oxide strips (12). The thin, single crystal silicon membranes thus formed are suitable for use as diaphragms and microbridges in a microaccelerometers or a pressure sensor.

Abstract: Frames of vectors of digital speech samples are buffered (11) and each frame analyzed to provide gain (G), pitch filtering (QP,QPP), linear-predictive coefficient filtering (QLPC) and perceptual weighting filter (W) parameters. Fixed vectors are stored in a VQ codebook (13). Zero-state response vectors are computed from the fixed vectors and stored in codebook (14) with the same index as the fixed vectors. Each input vector (s n ) is encoded by determining the index of the vector in codebook (13) corresponding to the vector in codebook (14) which best matches a zero-state response vector (v n ) obtained from the input vector (s n ) and the index is transmitted together with side information representing the parameters. The index also excites LPC synthesis filter (15) and pitch prediction filter (16) to produce a pitch prediction (ŝ n)  of the next speech vector. A receiver has a similar VQ codebook and decodes the side information to control similar LPC synthesis and pitch prediction filters to recover the speech after adaptive post-filtering.

Abstract: A SAW resonator disposed with an IDT electrode and reflector electrodes is formed on the surface of a piezoelectric substrate (11). Three pieces of the SAW resonator form an acoustic coupling by being disposed close to each other, electrode fingers comprising the IDT electrode (13a) in the center are all grounded, and IDT electrode fingers are electrically independent on the side to be connected to input-output terminals of the IDT electrodes (12a, 14a) disposed outside. As a result, three excitation modes having different propagation frequencies are generated which are used to attain a broad band SAW resonator filter. When these three pairs of the IDT electrode are electrically independent, a balanced input-output can be achieved, and excellent out-of-band rejection characteristics can be obtained.
