Granted: 1999-04-20
Abstract: In order to reduce volume and weight of a power supply of a compact portable telephone set and thus reduce the volume and weight of the compact portable telephone set itself, a P-channel power MOSFET is used as a power switching element, and a negative voltage, for example -11 volts, is applied across a source and a gate from a DC/DC converter to turn on the P-channel power MOSFET so that power is supplied from a battery which serves as one power supply.  When the gate and the source of the power MOSFET are maintained at the same potential, the power MOSFET is turned off and power is supplied from another power supply.

Title: Air shroud device for a blown film extrusion line
Inventor: CREE ROBERT E
IPC: B29C48/10
Filed: 1993-02-04
Granted: 2002-07-23
Abstract: An air shroud device for a conventional blown film extrusion line. The line has air cooling ring(s) to direct primary cooling air along the bubble to cool the film to the frost line. The air shroud device comprises an annular air shroud plenum having an annular air outlet at a level below the frost line. The shroud device is coaxial, of relatively large size so that its outlet mechanism is spaced substantially radially from the bubble and from the outlets of the air cooling ring(s).      The air shroud plenum receives air from a source uninfluenced by variable conditions, and provides a diffused source of the air about the bubble to serve as pseudo-ambient air. Secondary air flow induced by primary flow of cooling air from the air cooling ring(s) comprises air drawn from the spaced-apart air shroud device and not from ambient air.

Granted: 1998-11-24
Abstract: A cell exchanging apparatus which distributes cells input through a plurality of input lines to output lines by destination for output.  Without stopping the operation of the cell exchanging apparatus, active and standby cell switches of the cell exchanging apparatus can be changed over.  The cell exchanging apparatus comprises a first and second cell switches, input selectors for feeding input cells only to either of the first and second cell switches, and output selectors for outputting cells output from either of the first and second cell switches to an external system.  When a change-over is instructed by a system change-over signal, the input selectors start to feed input cells into the cell switch in the standby mode.  When detecting completion of cell output operation from the active cell switch, the output selectors select a new active cell switch.  Upon detection of completion of cell output operation from the former active cell switch, a controller sends an output permission signal to the new active cell switch.          Resultantly, the new active cell switch starts to output cells to the output selectors which then output the cells to an external system.

Title: Video and audio alerting system for a television network
Inventor: BOULANGER JEAN PIERRE M
IPC: G08B27/00
Filed: 1993-09-15
Granted: 2000-06-20
Abstract: A system for receiving emergency, warning or public interest messages from a remote agency and displaying the emergency or warning information on selected channels of a cable television network in order to provide a warning system for viewers of a cable television network having one or more cable channels. The system comprises communication interface means for receiving the emergency or warning messages; a processor for decoding the messages; and a controller for formatting and inserting the message on any of the cable channels. The emergency or warning message can be displayed on the cable video signal as a single line of static text or horizontally scrolling text, or as a page of static text or vertically scrolling text, and can be accompanied by a audio signal. The message can also be superimposed on an override video signal which is substituted for the cable video signal. The system includes the capability of displaying an abbreviated message on any of the cable channels. In a minimally disruptive way, the abbreviated message directs the viewers to a detailed message channel for viewing the entire emergency or warning message. The system can also include a channel scheduling manager which is coupled to the processor. The channel scheduling manager contains a record of the block-out periods for each channel. The processor utilizes the scheduling manager to block-out emergency or warning messages at pre-determined times, for example, during the airing of a commercial endorsement.
