Abstract: A battery operated portable device, or “lockator” facilitates location of a parked automobile within having an unknown or forgotten location. The lockator locks, unlocks and locates the automobile with a simplified user interface. The locator has a combined automobile door lock and unlock transmitter and GPS locator. Pressing a lock button both transmits a lock signal and substantially determines the automobile location. Pressing the unlock button transmits the unlock signal and determines the direction back to the location where the lock button was pressed. Left and right icons on the lockator direct the driver back to the vehicle. The icons blink at a rate indicative of the distance to the automobile and indicate if the driver is heading away from the automobile. Measures are take to conserve power drawn from a battery powering the lockator.

Abstract: A virtual reality system (200-323) stereoscopically projects a virtual reality images including a three dimensional image (245) having an interface image (250′) in a space observable by a user (100). The display system includes a substantially transparent display means (200) which also allows real images of real objects (850) to be combined or superimposed with the virtual reality images. Selective areas or characteristics of the real images are obstructed by a selective real image obstructer (860) to enhance viewing of selected virtual reality images while providing for viewing or real images or virtual images combined with real images in other viewing areas. The display system includes either a stereoscopic headset display system or a heads-up display system. The selective real images obstructer is a gray scale liquid crystal display included with the display system providing for adjustment of the size, shape and/or transparency of the obstruction of real images.

Abstract: The braking system of a vehicle is securely engaged in response to the operator of the vehicle causing the vehicle to stop. The braking system remains securely engaged upon detection of a fault such as a vehicle collision, a vehicle malfunction or a problem with the operator or operation of the vehicle, thereby improving vehicle safety. In the event of a collision, securely engaged brakes can significantly reduce resulting vehicle acceleration, potentially avoiding a secondary collision and reducing injuries experienced by the vehicle operator and passengers. In the event that no fault is detected, the braking system is disengaged in response to the operator accelerating the vehicle, either by pressing the gas pedal or releasing the brake pedal, thereby making the securely engaged brakes virtually unperceivable under normal operating circumstances. The rate of release of the braking system is responsive to the gas pedal position.

Abstract: The braking system of a vehicle is securely engaged in response to the operator of the vehicle causing the vehicle to stop. The braking system improves vehicle safety by remaining securely engaged upon detection of a fault such as a vehicle collision, an unintentional transmission shift, a vehicle malfunction or a problem with the operator or operation of the vehicle. In the event of a collision, securely engaged brakes can significantly reduce resulting vehicle acceleration, potentially avoiding a secondary collision and reducing injuries experienced by the vehicle operator and passengers. In the event that no fault is detected, the braking system is disengaged in response to the operator accelerating the vehicle, either by pressing the gas pedal or releasing the brake pedal, thereby making the securely engaged brakes virtually unperceivable under normal operating circumstances.

Abstract: A device generates a directional anti-sound beam by modulating an ultrasonic carrier with a sound canceling signal and exciting an ultrasonic transducer with the modulated signal. When the anti-sound beam is directed at a sound source, the level of sound from the sound source is reduced. A microphone monitors the resultant sound for adjusting the sound canceling signal. An alternate signal may be further modulated upon the anti-sound beam to provide a substitute sound at the sound source.

Abstract: A virtual reality system (860-862) stereoscopically projects virtual reality images including a three dimensional image (960, 962) having an interface image (962) in a space observable by a user (100). The display system includes a substantially transparent display (862) which also allows real images of real objects (950) to be combined or superimposed with the virtual reality images. Selective areas or characteristics of the real images are obstructed (893, 893′) by a selective real image obstructer (860) to enhance viewing of selected virtual reality images while providing for viewing or real images or virtual images combined with real images in other viewing areas. Icons (FIG. 21) are displayed opposite the real image obstructions in order that a second person can ascertain the nature of the information viewed by the viewer.

Abstract: A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. The digital camera has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject.

Abstract: The braking system of a vehicle is securely engaged in response to the operator of the vehicle causing the vehicle to stop. The vehicle being stopped is determined in response to several conditions including a predetermined time of stopping as well as suspensions settling time. The braking system remains securely engaged in the event of a moving vehicle colliding with the stopped vehicle. The braking system also remains securely engaged even if the foot of the operator is removed from the vehicle's brake pedal. The braking system is disengaged in response to the operator accelerating the vehicle, such as the operator's pressing of the vehicle's gas pedal, release of the vehicle's clutch and/or release of the vehicle's brake pedal. The rate of release of the braking system is responsive to the gas pedal position. The braking system is released rapidly in response to a substantially depressed gas pedal to facilitate a rapid start.

Abstract: A two dimensional display panel produces a time variable image composed of light emitting pixels. The pixels are generated by a light emitting phosphor distributed within the panel, the pixels radiate light in response to being excited by charging and triggering energy beams. The energy beams are relatively invisible and may be generated by lasers or solid state diode energy sources. Wave guides within the panel direct the energy beams to the pixels. The wave guides may be composed of fiber optic threads and the display panel comprised of a fabric of woven fiber optic threads wherein pixels are produced at intersections of the woven fiber optic threads. The brightness of the pixels are controlled by regulating the duty cycle of a column driver relative to the duty cycle of a row driver. The display energy beams are driven to facilitate interface with a pen-like pointing device. In one embodiment the pen receives relatively invisible energy beams and in another embodiment the pen receives visible pixel light.

Abstract: A computer system stereoscopically projects a three dimensional object having an interface image in a space observable by a user. The user controls the movement of a physical object within the space while observing both the three dimensionally projected object and the physical object. The computer system monitors the position of the user to determine the position of the interface image within the space and further monitors the movement of the physical object to determine its position. A control signal is generated in response to the position of the physical object intersecting the position of the interface image. For example, a word processing program is indicated by an interface image such as an icon including the letter “W” three dimensionally projected within the space. The word processing program is activated when the user's finger moves within the space to touch the projected icon.

Abstract: A system has an information display and a camera for visually observing an observer of the information display. The information display and camera may be part of personal computer equipped for video conferences. The observer controls movement of a pointer on the information display by changing positions. The pointer may be moved by corresponding rotation or movement of visually identifiable characteristic, such as a facial feature of the observer. The movement of the pointer may be independent of the area of the information display being viewed by the observer. Furthermore, the observer may control the information on the display by modifying a changeable visual characteristic. A closure of a left eye causes generation of a first control signal while closure of a right eye causes generation of a second control signal.
