Title: Method and apparatus for limiting call origination accompanied by executing application
Inventor: KAMIYA DAI
IPC: H04M1/2746
Filed: 2002-01-30
Granted: 2005-10-25
Abstract: When a Java application AP originates a call to a certain communication node, a Java application manager JAM refers to the history of outgoing/incoming calls and telephone directory data mentioned above to determine whether the call origination processing should be granted by checking whether the telephone number of the communication node, for which call origination is to be implemented, is included in the history of outgoing/incoming calls or the telephone directory data. The determination is based on an idea in which, if the telephone number of the communication node for which call origination is to be performed is included in the history of outgoing/incoming calls or the telephone directory data, then the call origination processing is valid on a basis of the recognition in that a portable telephone has performed communication with the communication node in the past or the user has recognized it as a communication partner.

Title: Low onset dual stage hybrid inflator
Inventor: HOSEY EDWARD O
IPC: B01J7/00
Filed: 2003-05-01
Granted: 2006-03-14
Abstract: A low onset dual stage hybrid inflator comprising a diffuser subassembly, a gas generator subassembly, and a pressure vessel. The dual stage inflator offers a variety of different output levels of inflation gas. The four main deployment scenarios for the dual stage inflator are primary output, staged output, full output, and secondary only. For primary output, only the stored gas is released from the inflator. For staged output, the stored gas is released and after a short period of time (i.e. 30 ms), the gas generant is ignited. For the full output, the stored gas is released from the dual stage inflator at the same time the gas generant is ignited.  For secondary output, only the gas generant subassembly is fired, and the hot gases from the gas generant subassembly mix with the stored gas. The combination of the hot gas and the stored gas has sufficient pressure to rupture the burst disk.

Abstract: This invention is an impact energy absorption device, in which a long part ( 1) made of a high strength material is disposed with its lengthwise direction kept different from an impact direction, and both terminals of the long part (1) are connected with columns (2) through upper platens (3) covering the upper face s of the columns (2) kept standing apart from each other with a predetermined distanc e (L), comprising a structural system, in which a deformation of the long part (1) caused by the impact force applied to it, causes the upper platens (3) to move for compressing or deflecting the columns (2), thereby absorbing the impact energy. The conventional column type energy absorption member is weak against an impact applied in a direction within a wide angle (.theta.) such as an impac t applied in an oblique direction. However, the energy absorption device of this invention c an exhibit an impact energy absorption capability even against an impact applie d in the direction within such a wide angle, equivalent or superior to that in the ca se where it fails in the axial direction. Furthermore, even if the parts used are damage d, they can be easily exchanged to allow restoration as an energy absorption device.

Abstract: Method and apparatus for protecting a wellhead drive assembly has a housing having a polish rod seal and utilizes standard flanges adapted to fit between the existing stuffing box of any wellhead drive assembly and the standard flange of a well for extending the longevity of the existing stuffing box. In another embodiment, the housing, with or without a polish rod seal, protects the wellhead drive assembly and sealing components from damage due to flushing pressures. The protector housing introduces a sealing ring adjacent the well end that seals around a tapered rod coupler of the polish rod when so lifted for preventing high flushing pressure from being exerted directly onto seal elements thereabove. As in the first embodiment, a polish rod seal can be fit to the housing for protecting a stuffing box portion of the wellhead assembly in addition to the sealing ring used for protection during flushing operations.

Abstract: A dimmer control system has a communication control loop that connects a master unit in series with a plurality of remote units, and it is superimposed in series on the dimmer load line so as to allow two-way communication between the master unit and remote units without affecting the operation of the load. Communications from the master to the remote units are encoded in loop current fluctuations, whereas communications from any remote to the master unit are encoded in loop voltage fluctuations. The master unit has a switched power supply, for use during normal LOAD ON operation, in tandem with a capacitive power supply, for use during LOAD OFF operation of the control units so as to minimize hum. The master unit power supply circuit provides an output rail voltage comprised of a reference voltage for the load superimposed with a control loop voltage for the voltage drop across the series-connected remote units. The master unit has a POWER OFF detection circuit and a non-volatile memory for storing system status information, so that when power is restored, the system can be restored to its former power level. The switch units are formed with a cover frame mounting a switch plate on a hinge axis allowing ON/OFF movement of an opposing side thereof. An array of LED light pipes is mounted in the switch plate aligned with the hinge axis, in order to minimize displacement of the light pipes during actuator movement.
