Filed: 2000-04-14
Abstract: Disclosed is a tooth type rolling cutter earth boring drill bit with secondary cutting elements on the tooth surfaces. The secondary cutting elements provide additional, relatively sharp edges that help cut hard rock. The teeth also have convex radiused buttresses at their bases to reduce the stresses the teeth experience when drilling through extremely hard rock. This allows the tooth bit to survive the high loads encountered when drilling hard, tough rock formations, without breaking the teeth.   The combination of teeth with secondary cutting elements and convex radiused buttresses at their base provide a tooth type rotary drill bit that has superior resistance to wear and breakage when drilling through hard, tough rock without significantly reducing the drilling rate of penetration when drilling through soft rock.

Title: System and method of verifying the authenticity of input signals
Inventor: CALAMATAS PHILIP J
IPC: B61D19/02
Filed: 2000-06-19
Abstract: A system verifies the authenticity of input signals used in the operation of an apparatus. The system includes two input registers, a microprocessor, and one circuit network for each input signal. Each circuit network generates twin binary signals in response to its input signal. Specifically, twin logic one signals are generated by a circuit network when its input signal goes active state. Conversely, twin logic zero signals are generated when the input signal goes inactive.      Each circuit network conveys the first binary signal to a dedicated location in one input register and the second binary signal, after inversion, to a dedicated, mirror-imaged location in the other input register. Whenever any bit in either or both input registers changes, the microprocessor reads both input registers to ascertain the state of the bits they contain. Specifically, the bits in the first input register are read and conveyed to a first work register, with the bits in the second input register being re-inverted, reordered to match again the bit order of the first input register, and conveyed to a second work register. The microprocessor then compares each bit read from one work register with its corresponding twin bit read from the other work register. As long as each bit and its corresponding twin bit match, the microprocessor allows the apparatus to operate according to the dictates of the input signal(s) received. If any bit and its corresponding twin bit fail to match, the microprocessor can take whatever protective action is deemed appropriate.

Title: Combined selector switch and serial multi-gb/s data pulse receiver
Inventor: BROWN ANTHONY D
IPC: G06F3/00
Filed: 2000-07-26
Abstract: A bit line selector switch is serially connected with a data sink for detecting high speed data transmissions, typically in the gigabit-per-second range, and a backplane having a plurality of data lines. The selector switch incorporates a selector circuit that operates in one of two modes, a first "selected", or ON, mode and a second "not selected", or OFF, mode. The selector circuit includes one, preferably differential, input. In one embodiment, a selector switch has a plurality of selector circuits thus allowing the switch to operate in both modes simultaneously. Data coupled to a differential input of the selector circuit will, when operating in the "selected" or ON mode, transmit the data to the data sink which be, for example, a memory device, processor, or the like. In the "not selected" or OFF mode, the selector circuit will pass any data received to a positive supply rail. Regardless of the mode of operation, the selector circuit presents to the coupled data lines an impedance which matches that of the data path coupling the selector circuit to the data line. The selector switch, which typically is comprised of four or less differential inputs, and thus a corresponding number of selector circuits, may be combined with other similar switches to form a multistage switch.

Title: Optical waveguide grating and production method therefor
Inventor: SAKAI TETSUYA
IPC: G02B6/34
Filed: 1997-03-27
Abstract: An optical waveguide grating with radiative mode-coupling properties, with exceptional stability and reliability as an optical component, wherein the central wavelength of the rejection band has a low temperature dependence, due to the use of silica glass doped with germanium and boron for the core. The rejection bandwidth can be narrowed without increasing the grating length by forming the radiative mode-coupled optical waveguide grating in an optical waveguide wherein the mean relative refractive index difference of the core is greater than that of optical communication waveguides. The rejection can be increased by reducing the occurrence of cases wherein propagation modes of the core coupled to cladding modes once again couple to the core in planar optical waveguide gratings formed by making periodic changes in the waveguide structure along the direction of propagation of light in an optical waveguide having a cladding with a lower refractive index than the core surrounding the core, by making the thickness of the cladding at least thirteen times the thickness of the core.

Title: Adaptive state space signal separation, discrimination and recovery architectures and their adaptations for use in dynamic environments
Inventor: ERTEN GAMZE
IPC: G10L21/0272
Filed: 1999-06-16
Abstract: This invention unifies a set of statistical signal processing, neuromorphic systems, and microelectronic implementation techniques for blind separation and recovery of mixed signals. A set of architectures, frameworks, algorithms, and devices for separating, discriminating, and recovering original signal sources by processing a set of received mixtures and functions of said signals are described. The adaptation inherent in the referenced architectures, frameworks, algorithms, and devices is based on processing of the received, measured, recorded or otherwise stored signals or functions thereof. There are multiple criteria that can be used alone or in conjunction with other criteria for achieving the separation and recovery of the original signal content from the signal mixtures. The composition adopts both discrete-time and continuous-time formulations with a view towards implementations in the digital as well as the analog domains of microelectronic circuits. This invention focuses on the development and formulation of dynamic architectures with adaptive update laws for multi-source blind signal separation/recovery. The system of the invention seeks to permit the adaptive blind separation and recovery of several unknown signals mixed together in changing interference environments with very minimal assumption on the original signals. The system of this invention has practical applications to non-multiplexed media sharing, adaptive interferer rejection, acoustic sensors, acoustic diagnostics, medical diagnostics and instrumentation, speech, voice, language recognition and processing, wired and wireless modulated communication signal receivers, and cellular communications. This invention also introduces a set of update laws and links minimization of mutual information and the information maximization of the output entropy function of a nonlinear neural network, specifically in relation to techniques for blind separation, discrimination and recovery of mixed signals. The system of the invention seeks to permit the adaptive blind separation and recovery of several unknown signals mixed together in changing interference environments with very minimal assumption on the original signals.
