Patent CA-2019343-A1 (CA)
IPC: G01V1/00
Filed: 1990-06-20
Abstract: The properties of porous material that is hydraulically coupled to a well through openings in cased or in uncased portions of the well are evaluated.  The process involves initiating a pressure wave, typically at the well head, so that the pressure oscillations extend to the porous material zone under investigation.  Flow of fluid between the well and formation changes the amplitude and frequency content of the oscillations traveling up and down the well.  That is, the oscillations are modulated from the form they would have in a like well with no hydraulic communication to the formation.  The properties of the formation are derived from these changes.

Title: Single-Block Filter for Antenna Duplexing and Antenna-Switched Diversity
Inventor: KIM JIN D
IPC: H04B7/04
Filed: 1990-09-19
Abstract: SINGLE-BLOCK FILTER FOR ANTENNA DUPLEXING AND ANTENNA-SWITCHED DIVERSITY            Abstract of the Disclosure A single-block ceramic filter (102) is coupled to two antennas (142 and 144) for providing both antenna duplexing and antenna-switched diversity in a duplex radio transceiver (100). One antenna (142) is coupled by the filter (102) to a transmitter (132), and both antennas (142 and 144) are switchably coupled by the filter (102) to a receiver (130) by diversity control circuitry (101) in response to a diversity control signal (137). A microcomputer (134) in the transceiver (100) is coupled to the receiver (130) for monitoring the received signal strength (135). When the received signal strength (135) drops in level indicating that the signal being received on one of the antennas (142 or 144) has become degraded due to fading or other interference, the microcomputer (134) changes the binary state of the diversity control signal (137) for switching the receiver (130) to the other one of the antennas (142 or 144).

Title: Automatic data placement method and apparatus
Inventor: FEIGENBAUM MITCHELL
IPC: G09B29/10
Filed: 1991-03-25
Abstract: A method for automatically placing objects on a surface in proximity to corresponding predetermined locations without collision with such locations or other objects by defining a distance dependent attractive force between each object and the corresponding location which increases with increasing distance between the object and the location, and defining distance dependent repulsive force between each object and its neighboring objects and locations, such repulsive force decreasing with increasing distance.  The initial position for each object is established in proximity with the corresponding location in accordance with predetermined criteria.          Thereafter the motion of the objects under the influence of such forces and of a frictional retarding force are determined by marginally stable incremental integration of such motion. The objects are statically placed at a predetermined target distance from the corresponding location at the position around the location at which the sum of the absolute values of the magnitudes of the forces acting on the object is at a minimum.

Abstract: N-CHANNEL CLAMP FOR ESD PROTECTION           IN SELF-ALIGNED SILICIDED CMOS PROCESS            ABSTRACT OF THE DISCLOSURE      An electrostatic discharge  (ESD) protection device is formed in an integrated circuit by an N-channel grounded-gate transistor.  This protection device has a polysilicon gate, just as other P- and N-channel transistors in the integrated circuit device, but the siliciding of the protection device is controlled  so  that  adverse  effects  of  ESD  events  are minimized.  The siliciding of the protection transistor near the gate is prevented by using a deposited oxide layer as a mask, and this oxide layer is also used to create sidewall spacers for the transistor gates.  The sidewall spacers are used  in  creating  self-aligned  silicided  areas over  the source/drain regions, self-aligned with the gates, for all P-and N-channel transistors except the protection transistors.

Abstract: ABSTRACT            The inventive structure involves the provision and use of a rotating, fluted, impeller having sling compartments along a side thereof in which frangible materials are progressively introduced, are subjected to impaction with respect to each other and from which, after a build-up of radial angular velocity of the bodies, are projected forwardly radially outwardly with maximized face against a striker abutment and each other within a side-positioned quadrant zone.   Thereafter,  the broken-up material bodies are advanced past a somewhat tangentially converging forward, space-restricting end of an adjustment plate which may be one member of a striker abutment assembly, by the impeller into a separating zone of passageway along which a fluid stream is counterflowed with respect to rotation of the impeller and employed to substantially immediately separate out broken-up particulates of a desired size from particles of greater than the desired size, with particles being returned to the impeller compartments and recycled with newly introduced material bodies and with the particulates being carried out of the apparatus by the fluid stream.   The shaft of the impeller  has  a  balanced,  two-way,   supporting,  working  area isolated, bearing mounting.
