Title: System for completing calls to roaming cellular telephone subscribers
Inventor: PEHLERT WILLIAM K
IPC: H04W8/06
Filed: 1993-11-12
Abstract: SYSTEM FOR COMPLETING CALLS TO ROAMING CELLULAR TELEPHONE SUBSCRIBERS          Abstract Cellular telephone cass are completed to roamers by arranging a Mobile Telephone Switching Office (MTSO) to forward to one or more elements in the Switched Telecommunication Network (STN), such as a centralized database accessible from the switches in the network, information enabling a call to a roaming cellular subscriber to be forwarded to the foreign service area MTSO serving that subscriber, without the need to route the call to the MTSO serving the subscribers home service area. The information provided by the MTSO can be the TDN or other information identifying the telephone number to which calls placed to the roaming cellular subscriber should be completed. The switch utilizing the information from the MTSO is typically the "originating switch" within the LEC or IXC network first receiving the call, but can be any switch within the STN through which calls to the home service area MTSO are routed. The MTSO sending the information is generally the home service area MTSO, but the foreign service area MTSO can alsoperform this function. When calls to the cellular subscriber are received in theswitch, "cellular" calls are differentiated from "other" calls, such as by using the NPA (area code) and/or NXX (telephone exchange) associated with the MTSO. For cellular calls, the database is queried; if the subscriber is roaming, the TDN or other stored information is retrieved and used to route the call through the STN to the foreign service area MTSO, without the necessity of the call being connected to,routed through, or forwarded by, the home service area MTSO. Under certain circumstances, the call can be routed to a wireline telephone. (Fig. 1)

Patent CA-2109732-A1 (CA)
Inventor: STROPE TODD R
IPC: G05B19/42
Filed: 1993-11-23
Abstract: An improved process for positioning a bevel along the edge  of  an opthamalic  lens  computes  point-to-wheel  data definitive of a planar relationship between the lens and the wheel,  stores the point-to-wheel data,  computes corrected horizontal displacement data definitive of a three dimensional relationship between the  lens,  the wheel  and a plot of sequential contact points therebetween using the computed point-to-wheel  data,   stores  the  corrected  horizontal displacement data, and controls the relative positions of the edging wheel  and the  lens  in  response to the corrected horizontal displacement data.    The point-to-wheel  data  is  computed by  sequentially testing at successive incremental points of the point-to-wheel data at a beginning reference angle of the lens to determine a transition point at which the wheel ceases to increase and begins to decrease its displacement from the lens.     This  sequential  testing  is  repeated  at  successive incremental points for sequentially successive incremental changes in the reference angle to determine a transition point for each incremental change.     The corrected horizontal displacement data is computed by sequentially testing at successive incremental angles of a radius originating at a center of rotation of the lens at a beginning  reference  angle  of the  lens  to  determine  an incremental angle at which the lens initiates contact with the wheel.   This sequential testing is repeated at successive incremental angles at each sequentially successive incremental change in the reference angle to determine an incremental angle at which the lens initiates contact with the wheel for each incremental change.     Preferably,  the  beginning  reference  angles  and  the successive incremental changes in the reference angle of the point-to-wheel  computing  and  the  corrected  horizontal displacement computing are identical and sequential testing at successive incremental points and at successive incremental angles occurs simultaneously for each sequentially successive incremental change in the reference angle.

Title: High-density read-only data storage
Inventor: SHOJI MASAKAZU
IPC: G11C17/12
Filed: 1994-10-12
Abstract: A read-only memory ("ROM") utilizing junction field-effect transistors ("JFETs") having a conductive channel orthogonally oriented with respect to the surface of the semiconductor material composing the JFET. A fixed-position ion beam is employed to create this narrow gate channel, which extends between the JFET's source and drain contact. Employing such JFETs as basic memory sites within a semiconductor ROM circuit allows for an architecture that conforms to a minimum lattice structure layout. In addition, the resulting ROM offers high speed access of data. Although JFETs have not been utilized as the transistor of choice within ROMs because of their seemingly inferior performance when compared to MOSFETs, the invention provides a novel architecture which significantly enhances the practicality of the JFET as a memory device.

Title: Engine block heater
Inventor: EDWARDS GARY C
IPC: F02F3/00
Filed: 1994-05-19
Abstract: A block heater for the cooling fluid of an engine block comprises a main body with a surrounding flange at the front face for engaging into an aperture in the block. A clamping element attached to the rear face can be actuated by a screw which is rotated from the front face to pull the clamping element into engagement with the inside surface of the block to cooperate with the flange in a clamping action. The clamping member cooperates with the screw to be pulled forwardly. The rear face of the clamping member has a countersink around the threaded bore therethrough and the screw has a bore in the end face thereof so that a portion of the screw material can be worked into a flange surrounding the end of the screw to engage into the countersink portion. This arrangement prevents reverse rotation of the screw from releasing the clamping member for discharge into the engine compartment.

Abstract: A complex signal correlator (106) and method therefor for correlating, at the multiple points in time, complex sampled (111) and reference (112) signals to produce a complex correlation signal (113). A relationship between the location of the reference signal (112) relative to the real and imaginary axes (301 and 302) is determined. The sampled signal (111) is processed responsive to the determined location) relative to the axes (301 and 302), of the reference signal (112) to produce real and imaginary processed components (210 and 211). The complex correlation signal (113) is produced responsive to adding (202-205) combinations of the real and imaginary processed components (210 and 211). Substituting adders (202-205) in the present invention for multipliers in the prior art complex signal correlators along with processing the sampled signal (111) significantly reduces the complexity of the complex signal correlator (106).

Title: Apparatus for Clamping and Welding
Inventor: QUAGLINE JAMES R
IPC: B23K26/10
Filed: 1994-06-29
Abstract: A clamping and welding apparatus for properly clamping and welding a pair of sheet materials within a welding station for both confined and accessible clamping and welding areas.  When sheet materials or body panels of automobiles arrive in a welding station, the body panels typically have welding locations that are in both accessible and confined areas.  In confined areas wherein the operation and maneuvering of the clamping and welding apparatus are hindered, the present invention provides a laser welder connected to the end of a programmable robotic arm that provides a wide range of movement to the laser welder independent of a clamp.  The clamp provides a pair of opposed clamp arms that are pivotally connected to a support member and whose pivotal movement is powered by a pair of clamp actuators units.  An aperture is provided through one of the clamp arms to guide and direct the laser welder to a proper position for providing a spot weld on the body panels.  When the welding location on the body panels is in an open and accessible area so that the operation and maneuvering of the clamping and welding apparatus is not hindered, the present invention fixedly mounts the laser welder to the clamp so that the laser welder moves with the clamp arm. The laser welder is mounted outside the plane in which the clamp moves between a clamping position and unclamped position so that clogging does not occur.
