Title: Ultra high density, non-volatile ferromagnetic random access memory
Inventor: PRINZ GARY A
IPC: G11C11/16
Filed: 1994-09-30
Abstract: A random access memoq element (100) utilizes giant magnetoresistance.  The element (100) includes at least one pair of ferromagnetic layers (106, 110) sandwiching a nonmagnetic conductive layer (108). At least one of the two ferromagnetic layers has a magnetic moment oriented within its own plane. The magnetic moment of at least the first ferromagnetic layer of the pair has its magnetic moment oriented within its own plane and is typically fixed in direction during use. The second ferromagnetic layer of the pair has a magnetic moment which has at least two preferred directions of orientation which may or may not reside within the plane of the second ferromagnetic layer. The bit of the memory element may be set by applying to the element a magnetic field which orients the magnetic moment of the second ferromagnetic layer in one or the other of these preferred orientations.  The set value is determined by the relative alignment of the magnetic moments of the first and second ferromagnetic layers.
Patent CA-2174691-A1 (CA)
Inventor: HENDRIX GEORGE E
IPC: B01D46/46
Filed: 1996-04-22
Abstract: A filter condition sensor and indicator is disclosed. A filter condition sensor and indicator that responds to the presence of a predetermined collection of material in a filter operatively positioned in an output air flow path. A small by-pass air flow path is connected to the output air flow path and is separate from the filter. A heated thermistor is positioned in the by-pass air flow path. Electrically connected in series with the heated thermistor is an indicator light that illuminates when the resistance in the circuit is decreased due to predetermined cooling of the heated thermistor. In this way, a predetermined collection of material in the filter increases the flow of air in the small by-pass air flow path for cooling the heated thermistor and for lowering the resistance in the circuit to illuminate the indicator light. Even in those instances where a multi-speed fan is located in the output air flow path, the present invention overcomes changing fan speeds and changing air velocity by coupling the thermistor in a circuit which changes the voltage and current through the thermistor depending on the fan setting.

Abstract: Automatic call forwarding techniques for use in conjunction with a telephonic communications system such as a PBX or a central switching office. A telephonic device is associated with a smart card reader/writer and a communications unit RF transceiver. Subscribers are each provided with a smart card and an RF jacket transceiver adapted to partially and removably encase the smart card. In response to input received from the smart card reader/writer, the telephonic device instructs the communications system to forward incoming telephone calls for a given subscriber to the associated telephonic device. The communications unit RF transceiver periodically transmits an interrogation signal to the RF jacket transceiver. If the interrogation signal is received by the RF jacket transceiver, the RF jacket transceiver sends an acknowledgment signal to the communications unit RF transceiver, and incoming calls will continue to be forwarded to the associated telephonic device. However, if the interrogation signal is not received by the RF jacket transceiver, the RF jacket transceiver does not transmit an acknowledgment signal, the communications unit RF transceiver does not receive the acknowledgment signal, and the communications unit RF transceiver causes the associated telephonic device to instruct the communications system to no longer forward incoming calls to the associated telephonic device. In a further embodiment, if the interrogation signal is not received by the RF jacket, incoming calls continue to be forwarded to the associated telephonic device until a predetermined time interval elapses, whereupon incoming calls are no longer forwarded to this associated telephonic device.

Abstract: A method and apparatus for determining the location of a mobile unit (412) within a cellular system. A synchronized signal at a common phase is generated at each base station (400, 401, 402) in a system. The mobile unit (412) transmits a signal tone. Each base station (400, 401, 402) compares the phase of the signal tone to the common phase of the synchronized signal to produce a phase offset. A system controller compares the difference between the phase offset of a first base station (400) and the phase offset of a second base station (401) and determines the difference in distance between the first base station (400) and the mobile unit (412) and the second base station (401) and the mobile unit (412) defining a hyperbolic or linear curve of locations. The system controller compares the difference between the phase offset of the first base station (400) and the phase offset of a third base station (402) and determines the difference in distance between the first base station (400) and the mobile unit (412) and the third base station (402) and the mobile unit (412) defining a second hyperbolic curve of locations. The system controller determines the intersection of the first and the second hyperbolic curves thus determining the location of the mobile unit (412).

Title: Barrel with lid
Inventor: PRZYTULLA DIETMAR
IPC: B65D1/20
Filed: 1995-09-12
Abstract: This invention relates to a cylindrical, blow-molded lidded barrel (wide-mouthed drum) with a barrel lid and tension-ring closure.      Previously known lidded barrels have comparatively little ability to withstand falls and are therefore not well-suited for handling liquids.      Owing to the special configuration of the barrel lid and the barrel mouth edges as well as by a special matching of the individual components to one another, the lidded barrel according to the invention can be manipulated in the filled state with the same barrel-gripping tool (parrot's beak), as is universally employed and in industrial use for modern plastic L-ring bung barrels or normal steel bung barrels. By improving the strength of the lidded barrel when it is dropped, the barrel is also made especially well-suited for handling liquids since it remains liquidtight even when dumped or dropped from great heights.

Title: Device for control of mice and other rodents
Inventor: WOODRUFF MARIE ANN
IPC: A01M23/18
Filed: 1997-03-24
Abstract: A device for controlling mice and other rodents includes a tubular housing having an opened rear end, a closed front end and a  spring  element  for  selectively closing the rear  end.   The housing is mounted at an inclined angle relative to a supporting platform which  opposes  the  force  of  the  spring  element  and maintains the rear end of the housing in its opened position when the housing is mounted on the supporting platform.  An attractant induces mice or other rodents into the housing which, as a result of the weight of the rodent, pivots relative to the supporting platform  resulting  in  disengagement  of the  rear  end  of  the housing and the supporting platform.   Upon disengagement,  the spring element closes the rear end of the housing entrapping the rodent therein.  Breathing openings covered by a removable seal can be provided in the housing to dispose of the trapped rodent in a living state.
