Appl. No.:

09/351997

Inventors:

Stephen P. Sample - Mountain View CA
Michael R. DAmour - Los Altos Hills CA
Thomas S. Payne - Union City CA

Assignee:

Quickturn Design Systems, Inc. - San Jose CA

International Classification:

G06G 778

US Classification:

703 24, 702118, 714725, 716 6

Abstract:

A system for physical emulation of electronic circuits or systems includes a data entry workstation where a user may input data representing the circuit or system configuration. This data is converted to a form suitable for programming an array of programmable gate elements provided with a richly interconnected architecture. Provision is made for externally connecting VLSI devices or other portions of a users circuit or system. A network of internal probing interconnections is made available by utilization of unused circuit paths in the programmable gate arrays.

Appl. No.:

09/753540

Inventors:

Thomas S. Payne - Union City CA 94587
James M. Payne - Rosamond CA 93560

International Classification:

B61G 1100

US Classification:

213221, 1053925, 105393

Abstract:

A train collision attenuator mounted on a leading end of a train for attenuating the force of impact between a moving train and a pedestrian or motor vehicle. The train collision attenuator includes an energy absorbing assembly and a mounting assembly. The energy absorbing assembly includes a leading surface and the energy absorbing assembly is dimensioned and configured for attenuating the force of impact between the moving train and the pedestrian located in the path of the moving train as the pedestrian impacts against the leading surface. The mounting assembly secures the energy absorbing assembly to the leading end of the train. A lifting mechanism for moving the energy absorbing assembly between a deployed position to a retracted position is also provided. A selectively-inflatable, externally-mounted airbag including an upper pedestrian cushioning portion and a lower pedestrian support portion is also provided. An energy absorbing hydraulic cylinder and a vehicle contact plate mounted on the hydraulic cylinder piston is also provided.

International Classification:

B61G 1100

US Classification:

213221, 213223, 1053925, 105394

Abstract:

A collision attenuating system for a moving vehicle including an energy-absorbing airbag assembly dimensioned and configured for attenuating the impact between the moving vehicle and a pedestrian or an impacted vehicle located in or crossing the path of the moving vehicle as the pedestrian or impacted vehicle impacts against the airbag assembly, a mounting bracket dimensioned and configured for being affixed to the moving vehicle, an engagement bracket affixed to the airbag assembly and engagable with the mounting bracket, and a quick-release fastener for removably engaging the engagement bracket to the mounting bracket for removably mounting the airbag assembly to the moving vehicle. The airbag assembly includes an airbag and an assembly frame supporting the airbag, a speed sensor for determining the speed of the vehicle, and a pressure regulator for controlling a pressure function of the airbag responsive to the speed sensor. The airbag assembly includes an upper deflatable airbag, and a lower pedestrian support, the pedestrian support including energy-absorbing structure. A method of using the collision attenuating system is also described.

International Classification:

B61G 1100

US Classification:

213221, 213223, 1053925, 105394

Abstract:

A collision attenuator for a vehicle including an energy absorbing cylinder, a mounting assembly adapted to secure the energy absorbing cylinder to an end of the vehicle, a contact plate mounted to the energy absorbing cylinder, a control valve for extending and retracting the energy absorbing cylinder in order to move the contact plate with respect to the end of the vehicle. A comparator is operably coupled with the control valve, wherein the comparator is configured to adjust the energy absorbing cylinder based upon a speed signal indicative of the speed of the moving vehicle. A coupler detector is operably coupled with the control valve, wherein the coupler detector inhibits the extension of the energy absorbing cylinder unless the coupler detector determines that the coupler is open. A pivot assembly pivotally secures the contact plate to the energy absorbing cylinder allowing the contact plate to pivot laterally about an upright axis with respect to the energy absorbing cylinder. A quick-release mechanism detachably secures the energy absorbing assembly to the end of the vehicle.
