Title: Automobile communications method and system
Inventor: YOSHIDA YASUHARU
IPC: G08G1/09
Filed: 1999-07-06
Abstract: An automobile communication system which can ensure fast hand-over without putting unnecessary burden on mobile stations and can adequately handle changes in road condition is disclosed. For each of the radio zones formed by roadside transceivers arranged along a road, a plurality of transmission and reception frequencies f t1/f r1 and f t2/f r2 are provided. The in-use transmission/reception frequencies in adjoining radio zones are switched at predetermined timing such that they are not permitted to be overlapped.      By switching a time slot allocated to the vehicle-mounted transceiver, the vehicle-mounted transceiver can continuously communicate with the roadside transceivers at the same communication frequency over the radio zones.

Patent CA-2279625-A1 (CA)
Title: Sterilization of organs and prostheses with coupling agents
Inventor: GIRARDOT JEAN-MARIE
IPC: A01N25/00
Filed: 1998-02-09
Abstract: Heart valves or other components for replacement of heart or other bodily organs and tissue prostheses or synthetic prosthetic materials are effectively sterilized by treatment with a coupling agent known to create amide linkages between amines and carboxylic acids in the presence of a lower alkanol. Such treatment has been shown to be bactericidal when carried out at 40 °C for over 1 hour. The sterilization treatment preferably employs EDC as a water-soluble coupling agent, plus an optional coupling enhancer such as sulfo NHS or NHS, in the presence of isopropanol or an equivalent alkanol. Such sterilization treatment is preferably carried out at a temperature above ambient temperature in a buffered aqueous solution. The treatment leaves no residuals other than ones which are nontoxic and biocompatible, does not affect the resistance of the tissue to thermal denaturation and to digestion by proteolytic enzymes, and surprisingly also increases the resistance of fixed biological tissue to calcification.

Title: A frequency/phase comparison circuit with gated reference and signal inputs
Inventor: SWAMINATHAN ASHOK
IPC: H04L27/00
Filed: 1999-11-25
Abstract: Disclosed is a frequency-locked loop (FLL), which attempts to bring about frequency and phase synchronization between two signals over the control bandwidth of the loop: a reference signal and a voltage-controlled oscillator (VCO) signal. For example, the FLL employs a reference signal generated by a crystal oscillator of frequency .function. REF and a VCO signal generated by the oscillations of an unquenched SRG resonator with tunable resonant frequency .function. RES.  These signals are connected to the inputs of a phase/frequency detector (PFD) which produces output pulses in response to the relationship between .function.REF  and .function.RES. These pulses are applied to a loop filter (LF) which creates a voltage using some kind of charge-storage element. This loop filter voltage is a so-called error voltage whose value is used to control the frequency of the resonator to bring the reference signal and VCO signal into phase synchrony.

Abstract: A system and method for wind-powered flight, comprising a low-speed, high-drag leading aircraft such as a kite, tethered to a low-speed, low-drag trailing aircraft, such as a glider. The leading aircraft is launched, and when the leading aircraft ascends into winds which are significantly greater than winds at the ground level and the takeoff velocity of the trailing aircraft, the leading aircraft begins to tow the trailing aircraft.  The trailing aircraft becomes airborne and can be flown at a low air speed to maintain a constant drag on the leading aircraft, which in turn provides thrust to maintain the trailing aircraft aloft at the lower altitude.
