Abstract: An accelerator pedal assembly (12) for electronically controlling a vehicle engine throttle includes a housing (18), a pedal arm (16) pivotally supported with respect to the housing (18), and a pedal pad (14) connected to a lower end (20) of the pedal arm (16). The pedal arm (16) is pivotable between an idle position and a maximum applied position as a pedal force is applied to the pedal pad (14).  Under certain conditions, the accelerator pedal arm (16) can be pivoted to a position that causes the automatic transmission (40) to kickdown by changing to a next lower gear. Under these conditions a feel is imparted to the driver's foot indicating that a downshift has occurred. To simulate this feel in a drive-by-wire application, the pedal arm (16) presents a cam surface (48) for interacting with a spring (50) that has a first end (52) seated within the housing (18) and a movable second end (54) for bias engagement with the pedal arm (16). The spring (50) includes a roller (60) mounted on the second end (54) that is forced into contact with a lobe (74) on the cam surface (48) when the pedal arm (16) is pivoted from a first operable position to a pre-determined kickdown position. As the roller (60) engages the lobe (74), the pedal force required to further pivot the pedal arm (16) is increased imparting a kickdown feel to the driver via the pedal pad (14).

Title: Laser processing power output stabilization
Inventor: JORDENS WILLIAM J
IPC: H01S3/00
Filed: 2000-02-10
Granted: 2007-03-27
Abstract: A Q-switched solid state laser system (24) operates in a pulse processing control system (10) that employs an autopulse mode and a pulse-on-position mode to stabilize the pulse-to-pulse laser energy delivered to a workpiece (20) that is moved by an X-Y positioner (18). In the autopulse mode, laser pulses are emitted at a near maximum PRF, but the pulses are blocked from reaching the workpiece by an external modulator (28, 32), such as an acousto-optic modulator ("AOM") or electro-optic modulator (also referred to as a Pockels cell). In the pulse-on-position mode, the laser emits a pulse in response to the positioner moving to a location on the workpiece that coincides with a commanded coordinate location. The processing control system delivers a stream of coordinate locations, some requiring processing, at a rate that moves the positioner and triggers the laser at about the near maximum PRF. The pulse processing control system sets the AOM to a transmissive state whenever a coordinate location requiring processing is commanded and otherwise sets the AOM to a blocking state. This pulse timing technique provides a nearly constant interpulse period for the laser, thereby improving its pulse-to-pulse energy stability at the near maximum PRF.

Title: Methods and apparatus for treating disc herniation
Inventor: FERREE BRET A
IPC: A61B17/56
Filed: 2000-05-30
Granted: 2009-01-20
Abstract: Methods and apparatus for treating disc herniation provide a conformable device which assumes a first shape associated with insertion and a second shape or expanded shape to occlude the defect which typically follows partial dissection. The device may take different forms according to the invention, including patches (900) size to cover the defect or plugs (1002) adapted to fill the defect. In a preferred embodiment, however, the device is a gel or other liquid or semi-liquid which solidifies to occlude the defect from within the body of the disc itself. In another preferred embodiment, a mesh screen (202) is collapsed into an elongated form for the purposes of insertion, thereby minimizing the size of the requisite incision while avoiding delicate surrounding nerves. Such a configuration also permits the use of instrumentation to install the device, including, for example, a hollow tube (1206) or sheath adapted to hold the collapsed screen (1206), and a push rod (1204) to expel the collapsed device out of the sheath (1204) for use in occluding the disc defect. A device according to the invention may further include one or more anchors (902) to assist in permanently affixing the device with respect to the defect.
