Title: Device for moving a valve flap
Inventor: JESSBERGER THOMAS
IPC: F02D11/08
Filed: 1998-06-24
Abstract: The invention relates to a device for moving a valve flap, especially in the intake system of an internal combustion engine. The inventive device consists of a vacuum cell (20) which performs a lengthways movement in dependence on the application of a negative pressure. Said lengthways movement is transmitted to a cross-member (15) via a coupling rod (16). Said cross-member (15) is connected to a lever of the valve flap (11). The coupling rod and cross-member system allows the vacuum cell to be arranged in any position in relation to the valve flap (11). The invention can be simplified further by amalgamating the diaphragm disk (27) with the cross-member (15) so that they form a single integral part. In this case, a force is exerted excentrically on the vacuum cell. Said force can be compensated by the diaphragm having a shape other than a round contour.
Patent CA-2299162-A1 (CA)
Inventor: RONCA DAVID RANDALL
IPC: G10L13/04
Filed: 2000-02-23
Abstract: A text-to-speech converter includes a text-to-speech engine receiving source text and converting the source text into speech data. A read mechanism reads speech data from the text-to-speech engine and writes the speech data to a buffer. A throttle mechanism reads speech data from the buffer and conveys the speech data to a playback operation. The throttle mechanism triggers the read mechanism to read data from the text-to-speech engine and writes the speech data to the buffer so that unread speech data in the buffer remains ahead of speech data read by the throttle mechanism by at least a predetermined amount.

Title: Mos varactor structure with engineered voltage control range
Inventor: INIEWSKI KRZYSZTOF
IPC: H01L27/08
Filed: 2000-06-09
Abstract: The present invention relates to a metal oxide semiconductor (MOS) varactor that takes advantage of the beneficial characteristics of MOS varactors to provide a high maximum to minimum capacitance ratio. By coupling in parallel at least one pair of MOS varactors with similar but shifted capacitance voltage (C-V) curves, the resulting capacitance is generally linear while preserving the desirable large capacitance ratio. A pair of MOS varactors, one with a p+ type gate and one with a n+ doped gate connected in parallel approximates the desired result. However, by adding further varactor elements, with their threshold voltages shifted by either implanting specific properties in their bodies or by providing offset voltages, a more linear C-V curve is attained while preserving the desired capacitance ratio.

Title: Microelectromechanical valve having single crystalline components and associated fabrication method
Inventor: DHULER VIJAYAKUMAR R
IPC: F16K31/02
Filed: 2000-08-29
Abstract: A microelectromechanical (MEMS) device is provided that includes a microelectronic substrate and a thermally actuated microactuator and associated components disposed on the substrate and formed as a unitary structure from a single crystalline material, wherein the associated components are actuated by the microactuator upon thermal actuation thereof. For example, the MEMS device may be a valve.  As such, the valve may include at least one valve plate that is controllably brought into engagement with at least one valve opening in the microelectronic substrate by selective actuation of the microactuator. While the MEMS device can include various microactuators, the microactuator advantageously includes a pair of spaced apart supports disposed on the substrate and at least one arched beam extending therebetween.  By heating the at least one arched beam of the microactuator, the arched beams will further arch such that the microactuator moves between a closed position in which the valve plate sealingly engages the valve opening and an open position in which the valve plate is at least partly disengaged from and does not seal the valve opening. The microactuator may further include metallization traces on distal portions of the arched beams to constrain the thermally actuated regions of arched beams to medial portions thereof. The valve may also include a latch for maintaining the valve plate in a desired position without requiring continuous energy input to the microactuator. An advantageous method for fabricating a MEMS valve having unitary structure single crystalline components is also provided.

Title: Pickup truck bed extender apparatus
Inventor: ALEXANDER JAMES W
IPC: B60R5/04
Filed: 2000-10-27
Abstract: A bed extender apparatus adapted for use with a pickup truck bed to functionally enlarge the useable cargo area within the truck bed when a tailgate is in a lowered position. The bed extender includes a center wall which is pivotably mounted to an inner surface of the tailgate, and which can be pivoted info an upright position once the tailgate is moved into a lowered position. A pair of end walls are pivotably secured to opposite ends of the center wall. Each end wall can be pivoted out to a position extending perpendicular to the center wall once the center wall is in its raised or operative position. Each of the end walls can then be secured to an associated one of the vertical walls of the pickup truck bed. A principal advantage of the bed extender is that the end walls and center wall each include a plurality of members which, when the end walls are folded against the center wall, form an extremely compact arrangement which takes up virtually no appreciable cargo space within the pickup truck bed. The bed extender also forms an extremely aerodynamically efficient structure when in use.

Title: Remotely controllable circuit breaker
Inventor: SIMMS KEVIN ANTHONY
IPC: H01H71/46
Filed: 2001-02-27
Abstract: A circuit breaker has a set of remotely controllable secondary contacts connected in series with the main contacts which provide overcurrent protection. The secondary contacts are opened and closed by a latching solenoid having a close coil and an open coil which are separately connected to switched terminals of a first switch. A voltage source, which may be ac, dc or pulsed, is connected to the common terminal of the first switch through a rectifier. The first switch is coupled to the plunger of the latching solenoid which opens and closes the set of secondary contacts and enables the coil which operates the set of secondary contacts to the opposite state. Energization of the enabled coil is completed by additional, remotely located switches connected between each coil and ground. A status line connected to one of the switched terminals of the first switch is energized when the associated coil is enabled to indicate the open/close status of the set of secondary contacts.
