Patent CA-2202316-A1 (CA)
Inventor: MIYOSHI TADAYOSHI
IPC: H01L23/12
Filed: 1997-04-10
Abstract: In an electronic device assembly, a tape carrier package carries an LSI (Large Scale Integrated Circuit) thereon and has through holes arranged bidimensionally in a film and electrically connected to the LSI by a wiring pattern. An insulating substrate has input/output pins thereon. The input/output pins are connected to pads provided on a mounting substrate, extending throughout and contacting the through holes of the tape carrier package. As a result, the LSI and mounting substrate are electrically connected by the input/output pins.     The taper carrier package can be fabricated as inexpensively as the state-of-the-art TBGA which is lower in cost than a similar wiring using a ceramic laminate substrate. Because the dielectric constant and other factors of the material constituting an insulating substrate do not have to be taken into account, there can be used the most inexpensive material.

Patent CA-2215075-A1 (CA)
IPC: H04W28/02
Filed: 1997-09-09
Abstract: This invention proposes a novel common packet data channel (CPDC) system structure and method to efficiently provide variable-rate packet data services in CDMA system. This system uses common code channels to serve packet data calls for a plurality of packet data users within a cell or sector. On the forward link (base station-to-mobile), an ATM-type multiplexing scheme is employed on a common code channel, while a spread ALOHA-type random access scheme is used on the reverse link (mobile-to-base station). The overhead due to call setup and channel assignment in a conventional circuit-switched system is not required in this system. The delay due to the call setup is reduced. In addition, ATM cells can be directly transmitted over the air interface. Novel transceiver architectures for the terminal and base station for implementing a system as well as particular channel signal structures are disclosed.

Patent CA-2230039-A1 (CA)
Title: Fabry-perot pressure sensing system with ratioed quadrature pulse detection
Inventor: HALL DAVID B
IPC: G01J3/26
Filed: 1998-02-19
Abstract: A pressure sensing system employs a plurality of pulsed, single-wavelength optical signal sources, each emitting a distinct wavelength, whereby a multiplexed incident beam is generated. The incident beam is split into a first portion directed to first photodetector means that generate a reference signal for each wavelength, and a second portion that interrogates one or more Fabry-Perot pressure sensors. The interrogation beam portion is phase-modulated by gap width variations in the sensor(s), and is transmitted to second photodetector means that generate a measured intensity signal for each wavelength. For each wavelength, the ratio of the measured intensity signal to the reference intensity signal is taken, and yields two terms, one of which is an interference term that is proportional to the cosine of the Fabry-Perot phase shift angle .phi., which is a function of the gap width. By choosing wavelengths that are in quadrature relationship for a nominal Fabry-Perot gap width, the algebraic differences can be taken among the ratios to yield two expressions proportional, respectively, to the cosine and sine of the phase shift angle .phi.. An arctangent calculation is used to obtain the measure of .phi., which is proportional to the gap width, which, in turn, is a known function of the pressure applied to the sensor. The optical sources may be pulsed sequentially to provide a time division-multiplexed incident beam, or simultaneously to provide a wavelength division-multiplexed incident beam.

Patent CA-2235087-A1 (CA)
Inventor: JACQUES DAVID R
IPC: F16K31/20
Filed: 1998-05-13
Abstract: A system for providing a liquid to a plant or tree stand comprising a liquid reservoir connected via tubing to a liquid control assembly having a liquid level control section positioned on the lower end of an adjustable vertical section with straps for attachment to a tree.          The liquid level control section comprises a lever arm/float assembly positioned within the tree stand for maintaining a predetermined liquid level within the tree stand.  As the liquid in the tree stand is depleted the float drops and the opposite end of a float lever arm penetrates a channel raising a metal ball which permits liquid to enter the tree stand through the liquid level control assembly connected to the tubing from the reservoir.  As the liquid rises in the tree stand, the float is forced upward causing the opposite end of the float lever to drop resulting in the metal ball lowering to seal the channel thereby stopping the liquid flow into the tree stand.

Title: Electronically operated lock
Inventor: ARMSTRONG STEVEN
IPC: E05B63/04
Filed: 1998-04-29
Abstract: An electronically operated lock has a latch mechanism which is operable by a rotatable spindle. The spindle can be rotated manually either by an inside turn lever or a key operated outside plug or rotated electronically. A pinion is secured to the spindle and a slider supported for vertical dis:placement has a vertical rack which cooperates with the pinion. The slider has vertically separated upper and lower control surfaces and a rotatable wheel gear has an eccentric axially extending finger located intermediate the upper and lower control surfaces. The wheel gear is driven by a single direction motor through gearing. The upper and lower control surfaces are selectively located so that when the finger is rotated in one direction from a 3:00 position to a 9:00 position, the displacement of the slider will displace the bolt to the retracted position and so that when the finger is rotated in that direction from the 9:00 position to the 3:00 position, the displacement of the slider will displace the bolt to the advanced position.
