Abstract: A vehicle operating system that assists a vehicle operator with locating a control input of a vehicle device so as to minimize operator distraction when operating the vehicle device. The system includes a camera having a first perspective view of the control input, a display readily observed by the operator, and a processor configured to process a signal from the camera to determine a hand position of a hand approaching the control input and output a display signal having a second perspective view of the control input that is dependent on the operator's hand position relative to the control input. The second perspective view corresponds to that of a virtual camera attached to the operator's forearm or wrist, and so provides a perspective view that is substantially fixed relative to the hand.

Abstract: A rotary control knob apparatus includes a stationary knob retainer having a cylindrical post and an annular knob that slides over the retainer post, where the exterior periphery of the retainer post has a distributed array of compliant protrusions that contact the inner periphery of the knob to provide a resilient sliding interference fit between the knob and the retainer post. In a preferred arrangement, the retainer is secured against the rear surface of a control panel trimplate, and the knob is axially captured between the trimplate and a retainer flange extending radially outward from the base of the cylindrical post.

Abstract: A spark plug coil assembly includes a primary core inside a secondary winding spool that is formed with a closed end. A terminal is embedded in the closed end of the spool and the secondary windings are terminated to the terminal, with the terminal being couplable to a spark plug. Ignition voltage generated in the secondary windings is thus routed to a center of the secondary windings to terminate at the terminal. No pole piece need be disposed between the primary core and the closed end of the spool.

By predicting the fuel pressure that will prevail during an injection event, the fuel delivered during the injection event can be accurately controlled.

Abstract: High priority data and low priority digital data are transmitted as primary and secondary data in hierarchically modulated, orthogonal frequency division multiplexing (OFDM) from an earth-orbiting satellite. To enable the transmitter amplifier to be operated with less back-off from saturation without clipping, the low priority OFDM symbols have fewer samples than the high priority OFDM symbols, and the high priority samples on which the low priority samples are superimposed are selected according to a first deterministic rule using sample power comparisons of the high priority samples to concentrate the low priority samples on those high priority samples having lower (optimally, the lowest) sample power. The low priority samples are distributed on the selected high priority samples according to a second deterministic rule relating the original low priority sample order to the original high priority sample order.

Abstract: A seat assembly is provided that can be sat upon by an occupant that detects the weight of the occupant. The seat assembly includes a seat cushion, a rotary sensor, and a linkage having a tip. The seat cushion deforms in response to the weight. The rotary sensor has a shaft that rotates about an axis and has an electrical output that is proportional to the angle of rotation of the shaft. The linkage underlies the seat surface and connects the seat surface to the shaft of the rotary sensor. As weight is placed on the seat the seat cushion deforms in response to the weight moving the tip and the linkage. The movement of the linkage rotates the shaft, which in turn, provides an electrical output that is proportional to the weight.

Abstract: A variable shim and valve seat assembly for applications in a solenoid actuated fuel injector includes a variable shim having a face, a valve seat having a top surface that interfaces with the face, and mating features integrated in the face of the variable shim and the top surface of the valve seat. The mating features provide axial displacement of the valve seat through rotation of the valve seat relative to the variable shim. The mating features may be ramped surfaces. The amount of seat displacement is dependent on the designed ramp angle, the number of ramps, and the degree of rotation. Once the desired valve stroke is set, the seat is welded to the injector body to achieve a leak free interface. Tight stroke setting tolerances can be achieved by applying an axial load to the seat during stroke setting and welding.

Abstract: A method and a system on a vehicle for activating a pedestrian protection device that has one or more sensors coupled to a fascia of the vehicle and activates the pedestrian protection device if the signal from a sensor is greater than a minimum threshold and less than a maximum threshold. Coupling the one or more sensors to the fascia improves sensitivity for detecting a collision with a pedestrian when compared to systems that do not couple the sensors to the fascia. Comparing the sensor signal to a minimum threshold and a maximum threshold helps avoid inappropriate or ineffective deployment of the pedestrian protection device. When multiple sensors are used, the location of the pedestrian collision on the fascia may be determined.

Abstract: A method and apparatus for controlling a fuel pump assembly comprising a plurality of pump elements for delivering fuel at high pressure to a rail volume, each of the pump elements comprising a plunger which is driven by an associated cam to perform at least one pumping event per engine revolution and a control valve for controlling fuel flow into and/or out of the pump chamber. Each pumping event corresponds to an associated cam lobe of the associated cam. The method comprises, for each pumping event of each pump element, controlling the control valve of said pump element in response to an output control signal derived from at least one previous pumping event. The output control signal is derived by measuring fuel pressure within the rail volume to derive a measured rail pressure value; and comparing the measured rail pressure value with a demanded rail pressure value to derive a rail pressure error.
