Patent number: 5272411Abstract: A triode having a coaxially positioned cathode and grid or gate electrode positioned within an evacuated tubular anode. The cathode has a plurality of emitting points radially disposed on its outer surface. The emitting points are surrounded by a plurality of grid or gate electrodes controlling the conducted beam current between the inner cathode and the surrounding anode. The gain and power of the triode is only limited by the number of emitter points and the number of grid or gate electrodes positioned within the anode. Since the anode envelopes the cathode and grid electrode, the anode can be used as a waveguide or antenna launch without the need of RF coupling connectors.Type: GrantFiled: January 28, 1992Date of Patent: December 21, 1993Assignee: ITT CorporationInventors: Frank F.

Patent number: 5271088Abstract: A speaker recognition apparatus employs a non-parametric baseline algorithm for speaker recognition which characterizes a given speaker's speech patterns by a set of speech feature vectors, and generates match scores which are sums of a ScoreA set equal to the average of the minimum Euclidean squared distance between the unknown speech frame and all reference frames of a given speaker over all frames of the unknown input, and ScoreB set equal to the average of the minimum Euclidean squared distance between each frame of the reference set to all frames of the unknown input. The performance on a queue of talkers is further improved by normalization of reference message match distances. The improved baseline algorithm addresses the co-channel problem of speaker spotting when plural speech signals are intermixed on the same channel by using a union of reference sets for pairs of speakers as the reference set for a co-channel signal, and/or by conversational state modelling.Type: GrantFiled: April 7, 1993Date of Patent: December 14, 1993Assignee: ITT CorporationInventor: Lawrence G.

Patent number: 5258602Abstract: A method for sensitive and precise determination of the temperature of a thin layer or wafer of bandgap material, without requiring contact to the layer or to the wafer, is based on selection of optical wavelength or wavelengths and the measurements of transmittance through the sample at such wavelength(s). The relationship between the temperature variations of the absorption coefficient, whether determined by band-to-band absorption or a totally different mechanism, and the measured transmittance, provide an indication of the sample temperature, without regard to the ambient temperature. The method prescribes how to select the wavelength(s) based both on the intrinsic properties of the material and on the practical considerations of the measurement situation.Type: GrantFiled: March 19, 1991Date of Patent: November 2, 1993Assignee: ITT CorporationInventors: Charles Naselli, Larry E.
