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. A digital apparatus 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. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.

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. The braking system may be released rapidly in response to a substantially depressed gas pedal to facilitate a rapid start or gradually in response to a partially depressed gas pedal to facilitate a smooth start.
Abstract:
A method of filtering a red-eye phenomenon from an acquired digital image including a multiplicity of pixels indicative of color, the pixels forming various shapes of the image, includes analyzing meta-data information, determining one or more regions within the digital image suspected as including red eye artifact, and determining, based at least in part on the meta-data analysis, whether the regions are actual red eye artifact. The meta-data information may include information describing conditions under which the image was acquired, captured and/or digitized, acquisition device-specific information, and/film information.
Abstract:
The invention is directed to temperature control system in which a programmable controller may be programmed to control a thermal output of said temperature-modifying device having a power connector. The programmable temperature control system may include at least one power coupler for removeably engaging the power connector from the temperature-modifying device. The programmable controller may be electrically coupled to the at least one power coupler and programmed to control the operation of the at least one temperature modifying device in response to the comparison of a measured temperature with at least one set point temperature. The power coupler may comprise one or more electrical outlets on the programmable temperature control system, for example, that may be used to individually control heating and cooling devices. The power controller may also include an power coupler for removeably engaging a power supply, such as an electrical outlet.
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. The braking system is released rapidly in response to a substantially depressed gas pedal to facilitate a rapid start or gradually in response to a partially depressed gas pedal to facilitate a smooth start.
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 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. In another embodiment, the invention has redundant energy beam sources and driving circuitry in order improve display system reliability. In another embodiment the wave guides have corresponding polarizers for producing alternating orthogonally polarized pixels of light for use in displaying stereoscopic three dimensional images from the two dimensional display panel. In another embodiment the wave guides are formed to allow intersecting energy beams from the arrays to enter the display at a single edge wherein the wave guides direct the energy beams to appropriate intersections, thereby freeing the remaining edges of the display for uses other than displayed image generation.
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. The braking system is release gradually in response to a partially depressed gas pedal to facilitate a smooth start.
