Title: Communications protocol for handling arbitrarily varying data strides in a distributed processing environment
Inventor: COLEMAN RONALD GERALD
IPC: G06F15/177
Filed: 1993-09-29
Granted: 1998-09-15
Abstract: Apparatus and an accompanying method for implementing a communications protocol for use in generally a distributed, and particularly a highly parallel,multi-processing system (5), for communicating application data of arbitrarily varying strides between separate processors and generally without the need for intermediate datastorage. Specifically, application data is transferred through a succession of packets (770) between originating and destination application programs (252), with each packetcontaining a partial data message. Each partial data message contains a portion of the data that is stored in a stride one portion of an originating application data memory (700). Upon reception, each data portion is written into a stride one portion of a destination application data memory (760). An application interface (254), executing independently at both the originating and destination processing elements (10 1, 10J+1) locally and respectively determines the starting address and length of each separate stride one data portion stored in the originating application data memory and for each separate stride one area in the destination application program memory that is to receive application data. Advantageously, through use of these independent application interfaces, application data can be transferred from the originating application data memory at one arbitrarily varying stride to the destination application memory with a different arbitrarily varying stride but without the need to pass the data through any input/output (I/O) buffers (632,634).

Abstract: Apparatus (10) for measuring the physical properties of an tube (T) or similar object using an ultrasonic testing method. A pulse generator (12) generates an electrical pulse having a predetermined set of characteristics. Transducers (20a, 20b) simultaneously convert the pulse to an ultrasonic waveform (W) and propagate the waveform at the tube from at least two different directions. The transducers then convert echoes (E1-E3) from the tube into electrical response pulses. Another transducer (24a) propagates a similar waveform at a reference object (B) and converts an echo from the reference object into a reference electrical response pulse. The reference response pulse is then combined with each of the other response pulses. Separate receivers (28a, 28b) receive the respective combined response pulses and converts them to digital data stored in a memory (32). A multi-channel processor (36) simultaneously, separately reconstructs each combined waveform and determines from each separate reconstruction a value representing a physical characteristic of the tube. Processing first involves performing a "real time" evaluation the combined waveform to determine if it meets threshold criteria. If so, the multi-channel processor performs linear interpolation and finite impulse responses on the digital data to precisely measure time of flight (TOF) values. A separate processor (54) includes a computing section (60) for mathematically combining the respective TOF values derived from the separate reconstructions to ascertain yet other physical characteristic values of the tube. Additionally, this processor includes a section (62) for comparing each physical characteristic value with a predetermined set of limits for each of the values to determine if the measured values fall within the limits. The results of the comparison can be displayed to an operator, and a permanent record of the values is also made.

Filed: 1994-07-19
Granted: 2005-08-30
Abstract: A temperature and static pressure compensated differential pressure sensor includes a semiconductor substrate in which a flexible, pressure responsive diaphragm is formed. A pressure responsive resonant microbeam is fabricated at the diaphragm periphery. For temperature compensation, a secondary resonant microbeam sensor is fabricated on the substrate at a peripheral location beyond the point of substrate attachment to a pressure tube or other support. For static pressure compensation, another secondary resonant microbeam can be positioned remote from the diaphragm and at a location of maximum substrate response to static pressure. A further resonan t microbeam can be mounted at die diaphragm center to augment the signal due to diaphragm deflections. Also disclosed is an accelerometer including a proof mass, a rigid rim surrounding the proof mass, and a series of narrow, flexible bridges supporting the proof mass relative to the rim. The bridges flex responsive to accelerations, thus to allow the proof mass to move relative to the rim. At least one of the bridges incorporates a resonant microbeam for measuring acceleration by virtue of die induced strain from flexure of its associated bridge. For temperature compensation, a secondary resonant microbeam is fabricated along the rim.

Title: Quadrupole with applied signal having off-resonance frequency
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1994-06-27
Granted: 2003-09-16
Abstract: A mass spectrometry method in which a combined field (comprising a trapping field and supplemental field) is established and at least one parameter of the combined field is changed to excite ions trapped in the combined field sequentially (such as for detection). The supplemental field is a periodically varying field having an off-resonance frequency, in the sense that the supplemental field frequency nearly matches (but differs from) a frequency of motion of an ion stably trapped by the trapping field alone. Sequential ion excitation in accordance with the invention can rapidly excite each ion to a degree sufficient for a desired purpose but insufficient for ejection from the trap. The amplitude of the supplemental field is kept sufficiently high to excite ions (via an off-resonance excitation mechanism) before they undergo resonant excitation.

Abstract: An improved filter apparatus (10) for removing debris from a free flowing water system (100) is described The apparatus has a rail (12) which is mounted adjacent the water supply intake opening (102) and extends upward from the floor (100A) of the water system at an incline. The apparatus has a continuous belt (36) made of chain links (38) and connectors (44) which mounts around an upper sprocket cylinder (26) at the top (12B) of the rail and around a lower sprocket cylinder (32) spaced above the bottom (12A) of the rail. The chain links allow for openings (42) in the belt which enable the belt to collect debris from the water flowing through the belt. The connectors have lifters (50) which move the debris collected on the front side 36A of the belt. The belt is loosely mounted around the sprocket cylinders which allows the lifters to tilt and dump any debris of excess weight back into the water system. The size and length of the connectors and the lifters is varied in order to change the weight limit at which the lifters tilt. The belt is moved upward by a motor (54) which rotates the upper sprocket cylinder. As the belt moves upward, the debris collected on the belt and by the lifters is moved out of the water system toward the top of the rail. As the belt moves over the upper sprocket cylinder, the upper sprocket teeth (28A) of the upper sprockets (28) extend through the openings of the belt loosening the debris trapped on the front side of the belt which falls into the collection trough (104). The upper sprocket teeth also scrape the sides of the openings in order to remove all debris and built up deposits. As the connectors move over the first sprocket cylinder, the lifters are turned upside down which dumps the debris into the trough beneath the top of the rail. A water pressure jet (60) sprays the remaining debris from the belt as the belt moves downward back into the water system.
