Title: Sensor unit for controlling a passenger restraint system in a vehicle
Inventor: DIRMEYER JOSEF
IPC: B60R21/00
Filed: 1993-04-20
Abstract: Abstract of the Disclosure:         A sensor assembly for controlling a passenger restraint system of a vehicle during an accident, such as an electronic tripping circuit of an air bag and belt tightening system of a motor vehicle, includes a sensor unit having a surface.  A breakage and deformation-vulnerable sensor configuration is disposed in the sensor unit for detecting at least one of acceleration and deceleration with a seismic composition.  A mount secures the sensor unit to an object, such as a part of a circuit housing.  A soft, resilient damping element con-tacts the surface of the sensor unit.  The damping element damps incident mechanical jarring of the sensor unit upon a hard impact, such as a bump occurring after an unintentional dropping of the circuit housing containing the sensor unit, in contrast to an impact acting directly on the sensor unit during an accident.

Title: Telephone ringing signal generator
Inventor: FAITH RICHARD W
IPC: H04M19/02
Filed: 1992-12-02
Abstract: A frequency conversion circuit includes four analog switching elements (46, 48, 52, 54) coupled. Each switching element is logic controlled to open or close, i.e., to have either a high or low conductivity to pass or block analog currents of either polarity.  Effectively, a signal received on the dual input (40, 42) may be enabled in inverted or non-inverted form onto the dual output (60, 62), depending on the control of the switches. The circuit may be used for producing a telephone ringing signal from an AC input signal. The circuit is coupled to receive an AC input signal, such as a 60 Hz signal derived from AC line power. The switching elements are alternately opened and closed during a predetermined sequence of half-cycles of the AC input signal. The circuit produces an output signal having a sequence of consecutive positive half-cycles and a sequence of consecutive negative half-cycles. Each switching element preferably includes a MOSFET switch stage providing either high or low impedance between two switch electrodes, a current amplifier (76, 78) for providing a gate voltage to the MOSFET switch stage, and a storage circuit including a capacitor (102) for storing energy while the switching element is open.

Title: Geographic-area selective low-earth satellite-based paging broadcast system and method
Inventor: FRENZER MICHAEL W
IPC: H04W68/00
Filed: 1993-08-23
Abstract: The present invention includes a low-earth satellite-based paging broadcast system (100) and method (200, 300) that maximizes spectral efficiency and minimizes power expenditure for the broadcast of paging messages by broadcasting the messages to terminator-or originator-selectable portions of the total system coverage area. The terminator selects a long-term preferred geographic area (LTPGA), and optionally, a short-term preferred geographic area (STPGA). The originator provides the terminator ID, the message, and optionally provides a customized preferred geographic area (CPGA). Terminators and originators can easily modify the selectable geographic areas (SGA(s)): LTPGA(s), STPGA(s), and CPGA(s). The gateway converts the SGA(s) to addressable coverage areas (ACA(s)), and transmits a signal including the paging information, and ACA(s) to at least a first communication satellite (COM SAT). The COM SAT(s) provide for crosslinking the signal to other COM SAT(s) and for broadcasting the paging information to the ACA(s).

Title: A fuel injector assembly
Inventor: RYNHART DEREK
IPC: F02M49/00
Filed: 1992-11-05
Abstract: ABSTRACT "A Fuel Injector Assembly"            A compression operated fuel injector assembly (1) for an internal combustion engine.  The injector assembly (1) has a body (2) with a bore (8) having a gas passage (9) at one end for communication with an engine combustion chamber. A piston (7) is slidable in the bore (8).  A fuel pump (5) is mounted within the body (2) having a plunger (14) which is mounted on  the piston  (7)  for reciprocal pumping movement within a complementary fuel pump cylinder (15) for delivery of fuel to a nozzle assembly (6).            The nozzle assembly (6) is mounted on the piston (7) and projects through the gas passage (9).  The piston (7) is urged downwardly by a timing spring (16) so that a valve head (18) on the nozzle assembly (6) engages a valve seat (19) until the pressure of combustion chamber gases acting on the outer portion of the nozzle (6) is sufficient to overcome spring pressure and move the piston (7) upwardly opening the passage (9) to the piston (7) so that the gases snap the piston (7) upwardly due to the increased area exposed to the gases.  Collets (20) at an outer end of the gas passageway (9) form a gas tight seal with a second valve head (21) on the nozzle assembly (6) when the piston (7) snaps inwardly to retain purging air within the bore  (8)  and  seal the bore  (8)  during combustion to exclude combustion gases.  When cylinder pressure drops at the end of the power stroke the spring (16) moves the piston (7) outwardly to blow down the purging air into the cylinder for improved scavenging.

Title: Scraper and brace attachment for a broom
Inventor: JUBINVILLE GISELE
IPC: A47L13/02
Filed: 1994-06-30
Abstract: A scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head and an upper end. The scraper device is comprised of a handle mounting member for connecting the scraper device to the handle, the handle mounting member defining an aperture which is sized to permit the handle to be accepted therein. A blade carrying member depends from the handle mounting member so that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the blade carrying member extends downwards and forwards over the head. The scraper device is further comprised of an anchoring system so that upward movement of the scraper device relative to the handle is restricted when it is attached to the broom. Finally, a scraper blade is located along the edge of the blade carrying member opposite the handle mounting member, so that debris may be scraped from a surface by the scraping device when the orientation of the broom is reversed from that normally used for sweeping. The scraper device may also comprise one or more bracing members for bracing the handle when the scraper device is attached to the broom.

IPC: G03F7/20
Filed: 1993-03-29
Abstract: A method of printing a sub-resolution device feature (16) having first and second edges spaced in close proximity to one another on a semiconductor substrate (20) includes the steps of first depositing a radiation-sensitive material on the substrate, then providing a first mask image segment (11) which corresponds to the first edge. The first mask image segment is then exposed with radiation (10) using an imaging tool (12) to produce a first pattern edge gradient (14). The first pattern edge gradient defines the first edge of the feature in the material. A second mask image segment (13) is then provided corresponding to the second feature edge. This second mask image segment is exposed to radiation (10) to produce a second pattern edge gradient (17) which defines the second edge of the feature. Once the radiation-sensitive material has been developed, the two-dimensional feature is reproduced on the substrate.
