Title: Discriminating fire sensor with thermal override copability
Inventor: KORN MARK T
IPC: G08B17/06
Filed: 1983-09-20
Granted: 1990-11-10
Abstract: The heat sensing device is in a channel which is responsive to longer wavelengths of the electromagnetic spectrum in, say, the far infrared region. The other channel responds in shorter wavelengths in the near infrared, say, in a range of 0.7 to 1.2 microns, defined by a filter. The heat sensing device may be a thermopile and receives radiation in the range from seven to thirt microns through a filter. The signals output by the two channels are passed to a NOR gate and monostable multivibrator which, therefore, outputs a signal only for significant amounts of radiation present simultaneously at both wavelengths. That signal is passed to an OR gate (54) of which the other input is supplied by the signal from the heat sensing device coupled through a threshold device.

Title: Apparatus and method for encoding speech
Inventor: KETCHUM RICHARD HARRY
IPC: G10L19/12
Filed: 1988-06-25
Granted: 1998-04-04
Abstract: Apparatus (101-112) for encoding speech uses an improved code excited linear predictive (CELP) encoder (102, 103, 104, 106, 107) using a recursive computational unit. In response to a target excitation vector that models a present frame of speech, the computational unit utilizes a finite impulse response linear predictive coding (LPC) filter and an overlapping codebook to determine a candidate excitation vector from the codebook that matches the target excitation vector after searching the entire codebook for the best match. For each candidate excitation vector accessed from the overlapping codebook, only one sample of the accessed vector and one sample of the previously accessed vector must have arithmetic operations performed on them to evaluate the new vector rather than all of the samples as is normal for CELP methods. For increased performance, a stochastically excited linear predictive (SELP) encoder (105, 107) is used in series with adaptive CELP encoder. The SELP encoder is responsive to the difference between the target excitation vector and the best matched candidate excitation vector to search its own overlapping codebook in a recursive manner to determine a candidate excitation vector that provides the best match. Both of the best matched candidate vectors are used in speech synthesis.

Inventor: AGHAJANIAN MICHAEL KEVORK
IPC: C04B35/65
Filed: 1989-01-07
Granted: 1997-02-21
Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the presence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy (20) spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy (20) can be placed adjacent to a permeable bedding of ceramic material (10) having a barrier, and brought to the molten state, preferably to at least about 700 DEG C, in order to form the net shape aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.

Abstract: The present invention relates to the formation of metal matrix composite bodies by a spontaneous infiltration technique, and novel metal matrix composite bodies produced according to the method. An ingot (4) of matrix metal is surrounded by a permeable mass of filler material (5). An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material (5), at least at some point during the process, which permit the shaped ingot (4) of matrix metal, when made molten, to spontaneously infiltrate the surrounding permeable mass of filler material (5). After the spontaneous infiltration, a metal matrix composite body is produced having therein a cavity which substantially corresponds in shape to the original ingot (4) of matrix metal.
