Title: Display panel sustain circuit enabling precise control of energy recovery
Inventor: MARCOTTE ROBERT G
IPC: G09G3/20
Filed: 1996-11-15
Abstract: An energy efficient driver circuit for driving a display panel having panel electrodes and panel capacitance includes an inductor means coupled to the panel electrodes; a driving voltage source; a voltage supply for providing a supply voltage of a magnitude which is greater than the driving voltage; a first switch device for selectively coupling the driving voltage to the inductor in response to a rising input signal transition, the input signal transition commencing a first state wherein a first current flow occurs through the inductor to charge the panel capacitance, the inductor causing the panel electrodes to rise to a voltage in excess of the driving voltage, at which point the first current flow reaches zero; and a second switch device for selectively coupling the voltage supply to the inductor and panel electrodes. A switch control is responsive to current flow in the inductor and is operative during the first state to initially maintain the second switch device in an open condition, and thereafter, in response to signals derived from the inductor, to cause a closure of the second switch device at a time which enables said second switch device to be fully conductive when the first current flow reaches zero, whereby the supply voltage source during a succeeding second state supplies current to both the panel electrodes and flyback current to said inductor. A like circuit is similarly operational on a falling input signal transition.

Title: Method and system in a wireless communications network for providing restricted user termination areas based on calling line identification and directory number
Inventor: STEPHENS GARY BOYD
IPC: H04W4/02
Filed: 1998-06-16
Abstract: A method and system product in a wireless communications network for limiting communication transactions are disclosed. Initially, a communications transaction from an originator to a primary recipient is initiated. An identity of the originator and an identity of the primary recipient are determined. A termination of the communications transaction is then restricted to a specified area based upon the identify of the originator or the identity of the primary recipient. Alternatively, the communications transaction can be restricted to a specified area based upon the identity of the primary recipient alone or based upon the identity of the originator alone, or in combination with one another. If the communications transaction is restricted to a specified area, a class of equivalent recipients that are allowable substitutes for the primary recipient are then identified. Next, it is determined which recipient among the equivalent recipients and the primary recipient is most advantageously suited to receive the communications transaction. The communications transaction is then automatically routed to the recipient most advantageously suited to receive the communications transaction. If no equivalent recipients are identified who are advantageously suited to respond to the communications transaction, alternative action is then implemented. The identity of the originator can include calling line identification information, and the identity of the primary recipient can include a directory number of the primary recipient.

Title: Pyridinecarboxamide derivatives
Inventor: HAMADA TAMIKO
IPC: C07D213/80
Filed: 1997-11-19
Abstract: N-(12-Nitroxydodecyl)-6-(4-ethyl or isoproyl-1-piperazinyl)pyridine-3-carboxamide or physiologically acceptable salts thereof. These compounds are excellent in the effects of inhibiting cerebral edema, particularly ischemic cerebral edema, and inhibiting delayed neuron death (or inhibiting calcium inflow into neuros). They are useful as a cerebral edema inhibitor or a cerebrovascular disorder remedy, because cerebral edema is a pathological condition accompanying cerebrovascular disorder, particularly one observed in an acute stage. Because also they scarcely exhibit any behavior suppressing activity believed to be a side effect in the therapy of cerebrovascular disorder in an acute stage, they are especially excellent as a remedy therefor. In addition, they have the effects of protecting the brain (i.e., an antianoxic effect), increasing cerebral blood flow, and inhibiting lipid peroxidation, which further enhance the usefulness as a cerebrovascular disorder remedy.

Patent CA-2244640-A1 (CA)
Title: Apparatus and method for pre-distortion correction of a power amplifier
Inventor: MERIDETH BRUCE
IPC: H04B1/04
Filed: 1998-08-10
Abstract: Linear and non-linear distortion in high power amplifiers used in television and digital television transmitters and amplifiers cause unwanted inter modulation products. Spectral regrowth limits the maximum power available from the amplifying device and can render it useless. Spectral regrowth from the amplifying device is caused from deviations in the amplifiers ability to reproduce the input signal multiplied by its gain. These deviations are caused by AM to AM and AM to PM conversion within the amplifier. Linear distortions due to frequency response errors and phase response errors can exist in the amplifier. When multiple amplifiers are combined in parallel in high power systems, these linear distortions interact with the non-linear distortions and can make conventional pre-correction circuits ineffective. The invention provides a method and apparatus for compensating or pre-correcting these linear and non-linear distortions.

Title: Apparatus for locating and sealing an injection molding nozzle
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/27
Filed: 1998-10-16
Abstract: Injection molding apparatus wherein a heated nozzle extends into an opening in a cooled mold. The nozzle has a rear locating flange and a front locating and sealing ring made of a deformable material. In the operating position, the rear locating flange contacts a first tapered shoulder around the opening and the front locating and sealing ring contacts a second tapered shoulder around the opening. The first and second tapered shoulders are further apart than the rear locating flange and the front locating and sealing ring. Thus, during insertion of the nozzle into place in the opening and thermal expansion of the nozzle, the rear locating flange first comes into contact with the first tapered shoulder to prealign the nozzle before the front locating and sealing ring comes into contact with the second shoulder and is partially deformed thereby to very accurately align the tip of the nozzle with the gate.

Title: Method of manufacturing fuel cells and fuel cells manufactured by the method
Inventor: MIZUNO SEIJI
IPC: H01M8/10
Filed: 1998-11-12
Abstract: The method of the present invention enhances the adhesive strength of a polymer electrolyte film via an adhesive and thereby manufactures a fuel cell having the high reliability for the gas sealing property.  The method exposes a joint body, which has been prepared by interposing a polymer electrolyte film between an anode and a cathode and bonding them, to an atmosphere having a temperature of 25°C and a humidity of 50% over one hour (S110).  The method then provides a pair of separators and applies an adhesive on specific areas of the separators,  which are directly joined with the polymer electrolyte film (S120).  The adhesive used here is a modified rubber adhesive that is a mixture of epoxy resin and modified silicone and has a modulus of elasticity of not greater than 10 MPa and a durometer A hardness of not greater than 90 after cure.  The method subsequently lays the pair of separators upon the joint body and cures the adhesive for bonding the separators directly to the polymer electrolyte film (S130 and S140).  The process of step S110 causes the polymer electrolyte film to have a water content ~ of not greater than 4.  This effectively ensures the sufficient adhesive strength of the polymer electrolyte film via the adhesive.

Filed: 1998-12-23
Abstract: Link performance is measured in a code division multiple access (CDMA) personal communication service (PCS) or cellular system, or other type of wireless system, using a test set-up which permits the simulation of various changes in system configuration. An illustrative embodiment includes a first attenuator arranged in a common portion of a receive path and a transmit path of a mobile station of the system, and a second attenuator arranged in either a receive-only portion of the receive path or a transmit-only portion of the transmit path. The amounts of attenuation provided by the first and second attenuators are decoupled such that a different amount of attenuation can be provided on the transmit path than on the receive path. Performance of forward and reverse links of the system are measured while varying a value of at least one of the first or second attenuators. For a given measurement, the attenuator values may be selected to simulate performance of the system in a configuration in which base station amplifier power is increased or decreased. As another example, the attenuator values may be selected to simulate performance of the system in a configuration in which cell size is increased. This arrangement of decoupled forward and reverse link attenuation in accordance with the invention permits efficient and accurate determination of link balance conditions.

Title: System and method for adaptive interference cancelling
Inventor: MARASH JOSEPH
IPC: H04B1/10
Filed: 1997-06-23
Abstract: An adaptive system and method for reducing interference in a signal received from an array of sensors. Adaptive filters are used to generate cancelling signals that closely approximate the interference present in the received signal. The adaptive filter weights are converted into the frequency domain where the frequency representation values in a selected frequency range are truncated to avoid signal leakage involving narrow band signals. Decolorizing filters are used to produce the cancelling signals having a flat frequency spectrum. Normalized power difference is used to limit the operation of the adaptive filters to the case where there is some directional interference to be eliminated.
