Inventor: DIEBEL DAVID A
IPC: B60R25/10
Filed: 1996-09-05
Abstract: An anti-theft sensor contact mechanism for an ignition system of an automotive vehicle has a sensor contact mechanism 24 which utilizes a non-conducting lever 46 to sense the physical presence of a lock liner 26 within a lock cylinder 28 of the ignition system and to depress a moveable contact 40 against a stationary contact 38 of the same metal for closing a path in an electrical monitoring, or sensing, circuit 32. When the lock liner 26 is removed, such as when tampered with during theft of the vehicle, the sensor contact mechanism 24 causes a break in an electrical path in the circuit 32 through movement of the moveable contact 40 to a non-contacting position with the stationary contact 38 so that a conventional alarm system may be triggered to sound an audible or visible Electrical continuity between the contacts 38,40 is enhanced by enclosing them within a housing 34 through which the lever 46 protrudes to prevent dirt, grease, oil, and other surface coating debris from inhibiting electrical contact therebetween. The electrical circuit 32 is not grounded through the steering column casting 30 through the lever 46 or either the stationary or moveable contacts 38,40, but is grounded through continuous wires 64,66 attached to the contacts.

Title: Method and apparatus for controlling pacemaker during automatic capture detection
Inventor: MARKOWITZ H TOBY
IPC: A61N1/365
Filed: 1995-05-19
Abstract: A cardiac pacemaker improves battery longevity by automatically providing optimized threshold amplitude and pulse width values. During capture verification and threshold searching, the pacemaker delivers a pacing pulse and a rapid, maximum amplitude backup pulse in case the pacing pulse fails to capture a patient's heart. Unlike the prior art, the backup pulse is delivered before a predefined Vulnerable Period (during which time pacing might lead to re-entrant tachycardia or fibrillation.) This results in threshold searching which is quick, accurate and with smaller rate drops during loss of capture.  In another aspect of the present invention, a diagnostic strength-duration curve is approximated by first setting the pulse width to a maximum value and determining the amplitude threshold (rheobase), and then by doubling the amplitude and determining the pulse width threshold (chronaxie).

Inventor: FELLMAN HANNU ANTERO
IPC: D21B1/02
Filed: 1997-02-11
Abstract: A wood chip conditioner that uses at least two closely spaced, counter-rotating rolls having a regular, wave shaped profile formed into their surfaces having a repeating pattern of peaks and valleys that radially circumscribes the roll and which are preferably the same dimension and offset from each other so that a peak on one roll is in registry with a valley on the other roll and form a nip through which oversized wood chips traverse. The chips passing through the nip are destructured by being bent and compressed by the surfaces on the rolls, which produces internal cracks along the grain of the wood without penetrating the chips. The rolls are also designed to avoid breaking or fracturing the chips, which would increase the occurrence of undesirable pins and fines. The surface of the peaks preferably also have shallow, equally-spaced grooves that extend axially. The grooves provide an edge that catches and pulls the chips into and through the nip. The bending action to which the chips traversingthrough the nip are subjected also loosens or dislodges the bark on the outer surface of the chips by breaking the bond between the bark and the chip. The present invention also includes a method of using the wood chip conditioner to destructure and remove moisture from fuel chips.

Title: Thermophilic strand displacement amplifications using avai
Inventor: PEARSON ROBERT E
IPC: C07H21/04
Filed: 1997-07-16
Abstract: The mesophilic restriction endonuclease AvaI and its isoschizomers derived from Anabaena and Anabaenopsis have been found to support highly efficient amplification of target nucleic acid sequences in thermophilic Strand Displacement Amplification (tSDA). The maximum amplification factors observed occurred at temperatures which were previously reported to result in reduced enzyme activity. As AvaI is an isoschizomer of BsoBI (a thermophilic restriction endonuclease commonly used in tSDA), the invention provides an alternative enzyme which is more readily available than BsoBI and does not require the redesign of SDA amplification primers previously constructed for use in the BsoBI system.

Title: Voltage and current based control and triggering for isolator surge protector
Inventor: TACHICK HENRY N
IPC: H02H3/50
Filed: 1997-09-22
Abstract: An isolator surge protector (ISP) is provided which blocks DC current and passes AC current and AC and DC fault currents. The ISP includes a main bypass path, including main bypass path switching devices, that is connected in parallel with a DC blocking capacitor.      Primary triggering of the main bypass path switching devices occurs when the voltage across the ISP exceeds a primary voltage trigger level. Repeated triggering of the bypass path switching devices, and high current discharge of the high voltage DC blocking capacitor through the bypass path, under abnormal steady state voltage conditions, is prevented by initiating a secondary triggering period following primary triggering of the bypass path switching devices. During the extended secondary triggering period, triggering of the bypass path switching devices occurs at a low secondary voltage trigger level. Primary triggering of the bypass path switching devices preferably also occurs when the AC current in the DC blocking capacitor exceeds a selected primary current trigger level, thereby protecting the DC blocking capacitor from damage due to excessive currents. Primary triggering due to high AC current levels in the DC blocking capacitor is also followed by a secondary triggering period during which triggering of the bypass path SCRs occurs at the low secondary voltage trigger level. The ISP preferably also provides a warning indication when primary triggering of the bypass path switching devices occurs.

Title: Hydraulic pump control system
Inventor: SAMEJIMA MAKOTO
IPC: G05B13/02
Filed: 1997-12-22
Abstract: Disclosed is a hydraulic pump control system which can control the absorbing torque of a hydraulic pump with respect to the engine power in a well-balanced manner, and reduce a deviation of an actual revolution number from a target revolution number of the engine. A torque (Tp) of hydraulic pumps during operation is estimated from a pump pressure (Pp) and first and second line pressures (Pr1, Pr2). Based on the estimated torque (Tp), an output torque (Tr) of the hydraulic pumps is controlled so that an error (.DELTA.Ne) between a target revolution number (Nset) and an actual revolution number (Ns) of the engine becomes null. The controlling of the output torque (Tr) of the hydraulic pumps is learned by a fuzzy control system.
