Title: Solenoid quick exhaust circuit for improved anti-lock performance in an electronic braking system
Inventor: AMATO WILLIAM P
IPC: H02H9/04
Filed: 2000-08-04
Abstract: A system and method are provided for controlling an anti-lock braking system  (ABS) in a motor vehicle where the ABS is performed by an electronic braking  system (EBS) which includes a pulse width modulating (PWM) drive circuit connected to a solenoid (30) in a modulator valve (20). The modulator valve controls air from a pressurized air source (12) to a brake cylinder. The PWM  drive circuit (100) allows the solenoid to accurately control the pressure t o the brake cylinder during the braking operation to control the smoothness of  the current and force profiles. During steady-state control operation of the  system, a diode (146) in the drive circuit is connected in parallel with the  solenoid. When quick dissipation occurs, the diode is eliminated from the circuit by opening the drive circuit with a high-side and low-side switch system (44, 120). This allows for optimal performance of the drive circuit when the EBS is in either the steady-state or quick dissipation mode.</SDOAB >

Title: Vascular grafts and methods for bridging a vessel side branch
Inventor: DEHDASHTIAN MARK
IPC: A61F2/06
Filed: 2000-01-19
Abstract: A vascular graft (20) for a primary vessel (22) adapted to bridge a side branch (24). The graft is especially useful for providing a support tube for a primary graft in the primary vessel on one side of the side branch. The graft includes first and second tubular sections separated by a gap. A bridging member (54) connects the first (50) and second tubular sections (52) across the gap and may include a relatively rigid strut to prohibit relative axial movement of the two sections. There may be one, two or more bridging members to define one, two or more apertures through which blood can flow from within the graft through to the vessel side branch.  The graft may include a flexible, desirably fabric, body supported by a wireform stent that is either self- or balloon-expandable. The graft may be deployed within the abdominal aorta on both sides of the renal arteries and have two apertures for blood to flow from the aorta to the renals. The infra-renal section provides a uniform uniform tubular anchoring surface for a trunk portion of a bifurcated graft used to repair an abdominal aneurysm extending to the iliac arteries.

Title: Laser system and method for processing a memory link with a burst of laser pulses having ultrashort pulsewidths
Inventor: SUN YUNLONG
IPC: B23K26/06
Filed: 2001-01-09
Abstract: A burst of ultrashort laser pulses is employed to sever a conductive link (22) in a nonthermal manner and offers a wider processing window, eliminates undesirable HAZ effects, and achieves superior severed link quality. The duration of the burst is preferably in the range of 10 ns to 500 ns; and the pulse width of each laser pulse within the burst is generally shorter than 25 ps, preferablyshorter than or equal to 10 ps, and most preferably about 10 ps to 100 fs or shorter. The burst can be treated as a single "pulse" by conventional laser positioning systems (62) to perform on-the-fly link removal without stopping whenever the laser system (60) fires a burst of laser pulses at each link (22). Conventional wavelengths or their harmonics can be employed.

Patent CA-2397131-A1 (CA)
Inventor: HALFORD STEVEN
IPC: H04B7/08
Filed: 2001-01-31
Abstract: A signal separator (42) overcomes co-linear interference encountered in a wireless communication system base station by exploiting generally flat fading characteristics of incoming signals. For this purpose, the invention employs diversity gained through the use of antenna array elements having different polarizations. An RF downconverter (53-58) provides a signal separator with baseband, discrete-time digital samples of signal waveforms, received at one or more pairs of diverse polarization antenna elements (53-58). The signal separator weights and combines the baseband signals from the vertically and horizontally polarized received signals produced by the RF downconverter to estimate which signals emanate from which users. The signal separator uses polarization coefficients supplied by a coefficient calculator (43). To generate the polarization coefficients, the coefficient calculator is coupled to receive a set of channel fading coefficients from a channel estimator (44). Estimates of the channel fading coefficients may be derived using standard signal processing algorithms using the peak values and the known cross-correlation between training patterns. The coefficient calculator computes the polarization coefficients required by the signal separator by means of a coefficient matrix such that the output of the signal separator is equal to the user's information signal.
