Abstract: A heating method and apparatus for vehicles.  A viscous fluid type heater is located in a vehicle fluid circuit. The heater has a heating chamber that holds viscous fluid and a rotor.  The rotor rotates to shear the viscous fluid and produce heat.  The heat is transmitted to a heat exchange chamber located adjacent to the heating chamber. The rotor rotates at variable rotation velocity, which affects the temperature of the viscous fluid.  Circulating fluid in the fluid circuit and is heated in the heat exchange chamber.  The heater includes a reservoir chamber communicating with the heating chamber to store viscous fluid.  The heater has a valve that selectively connects and disconnects the reservoir chamber with the heating chamber to regulate heat production.

Title: Fgfr3 as a marker for mesenchymal skeletal progenitor cells
Inventor: NEVO ZVI
IPC: A61K39/00
Filed: 1996-06-12
Abstract: The present invention concerns fibroblast growth factor receptor 3 (FGFR3) as a novel marker for mesenchymal skeletal progenitor cells. By utilizing this novel marker it was possible both to identify and locate mesenchymal skeletal progenitor cells in a tissue, as well as to obtain a substantially pure culture of such cells. The pure culture of the mesenchymal skeletal progenitor cells may be used, optionally after various manipulations ex vivo, as an active ingredient in pharmaceutical compositions or implants for the purpose of bone and/or cartilage repair. FGFR3 may also be used as a marker for the identification and the localization of cartilage- and bone-derived tumors.  Agents capable of binding to FGFR3 may also be used for targeting cytotoxic agents to cartilage- and bone-derived tumors.

Title: Drifting datum marker buoy
Inventor: LEGER GREGORY T
IPC: B63C9/20
Filed: 1998-04-07
Abstract: This invention relates to a drifting marker buoy that exhibits dual drift characteristics. These characteristics emulate the drift of a person in water, i.e. a minimum leeway object, as well as a larger object such as a life raft in water, i.e. a maximum leeway object. The marker buoy is capable of being packaged within a small housing and can be easily air or water deployed using, for example, a small military "A-size" launch tube. The buoy can be monitored by a variety of means and adapted so that it is capable of acquiring geographical self-location data via satellite-based positioning systems. Incorporating a configurable drift object, in a sonobuoy air launch package, along with the capability of a wave crest sensor represents a significant advance in SAR buoy technology.

Inventor: LI LONG-JANG
IPC: F16K31/06
Filed: 1998-09-25
Abstract: An apparatus detects a position of an armature within a solenoid coil by superimposing a fixed frequency sensing signal onto the coil driver signal.  The combined signal is applied to the solenoid coil and an alternating current component varies with changes in inductance of the solenoid coil that result from position changes of the armature.  A current sensor produces an output signal indicating a level of current flowing through the solenoid coil and a filter extracts the alternating component of that output signal that results from the sensing signal.  A position circuit determines the position of the armature from an output from the filter.

Title: Phase modulated reduction of clock wander in synchronous wide area networks
Inventor: ACIMOVIC PREDRAG
IPC: H03L7/091
Filed: 1998-11-18
Abstract: A phase detector for controlling a phase locked loop having a voltage controlled oscillator. A counter is clocked by a clock signal produced by the voltage controlled oscillator. A latch coupled to the counter is clocked by a modulated clock signal to latch values output by the counter. The modulated clock signal is produced by a phase modulator which modulates a synchronization clock reference signal. An accumulator coupled to the latch and clocked by the modulated clock signal receives and averages the latch values to produce a phase error signal representative of phase difference between the voltage controlled oscillator clock signal and the synchronization clock reference signal.      The phase error signal is coupled to the voltage controlled oscillator to reduce the phase difference. The phase modulator modulates a rising edge of the synchronization clock reference signal with a modulation signal having modulation frequencies outside the loop bandwidth of the phase locked loop. The modulation signal is a discrete step signal having a fine time resolution which causes the latch to latch different values output by the counter in different time intervals corresponding to the time of occurrence of the modulated clock signal's rising edge with respect to the respective time intervals.
