An interactive video display system uses strobing light to allow easy and unencumbered interaction between a person and projected video images. A camera may be synchronized to the strobing light and the strobing light may be in an infrared spectral range. A processing system detects images of a human in the field of view of the camera and controls the display so that the projected video images are changed based on an interaction between the human and the projected video images. The system may project the video images on a surface around the person and may move the projected video images on the surface based on a movement of the person. The projected video images may include computer-generated characters and/or virtual objects that react to the movement of a person.

A one camera system that measures golf club and golf ball kinematics is disclosed. Preferably, a plurality of retroreflective or fluorescent markers are placed on the surface of a golf ball. Using a single strobe lamps, images of a golf ball at two points in motion are acquired. The output of each of the strobe lamps is preferably filtered to pass predetermined colors of light. The input to each of the cameras is also preferably filtered. The output from the strobe lamp passes through at least one of a beam splitting mirror and reflective front surface mirror. Based on the filtered light outputs generated by the strobe lamp and the filtered camera input, at least two images of the golf ball, taken from two different angles, may be acquired. The acquired images may be used to analyze the kinematics of the golf ball.

A warning system (20) includes a central control unit (CCU), and a plurality of local units (LU) connected to the central control unit (CCU). Each local unit (LU) includes a plurality of input trips (An), such as smoke detector, an earthquake detector, and gas detector, and a plurality of programmable responses, such as a bypass relay (C), a message delivered by a record/playback unit (D), an emergency light (E), and a strobe light (F). The input trips (An) also include a disconnect trip (A1), which is activated by a detector input signal (DI) sent from the central control unit (CCU), and indicates that the central control unit (CCU) has malfunctioned. The programmable responses include a warning output signal (WO) which is sent from the local unit (LU) to the central control unit (CCU) to indicate the presence of a local emergency at the local unit (LU).

A printer-built-in image-sensing apparatus including a camera which performs image sensing with film exposure, and a printer which prints an image sensed by the camera. After a shutter button has been pressed and image sensing with strobe light emission has been performed, if printing is instructed by pressing of a print button, then electric charging a capacitor of a strobe circuit is made after the completion of the print operation. Otherwise, the charging of the capacitor is started immediately after the image sensing. In this case, even if printing is instructed during the electric charge, printing is started after completion of the electric charge. Thus, electric consumption upon print operation can be reduced and fluctuation of voltage can be suppressed.

A strobe apparatus of the present invention has a xenon tube, which is a discharge tube, having a discharge light emitting portion and a light emitting portion terminal. Light is emitting from the xenon tube and is reflected in a predetermined direction by a reflection umbrella. A transparent electrode is coated on the external surface of the xenon tube from the discharge light emitting portion to the terminal. When trigger voltage is applied to the xenon tube through the transparent electrode, strobe light is emitted by the discharge light emitting portion. By using the strode apparatus, the orientation characteristic of the discharge tube can be improved without uneven light distribution and a shortage of a light amount.

There is disclosed a constitution in which an area with strobe light rays dominant therein, which corresponds to strobe light dominant area, is extracted in accordance with various extraction conditions, and a white balance adjustment suitable for a property of the area is set in order to enhance a result of an indoor strobe photographing. Moreover, it is judged whether or not correction is appropriate for each white balance area in accordance with a result of evaluation exposure of a steady light amount.

A light emitting diode (LED) warning signal light, the warning signal light comprising a plurality of light sources constructed and arranged with a reflector or culminator, the LED light source being in electrical communication with a controller and a power supply, battery, or other electrical source.

A plurality of fiber optic lines are disposed in the borescope housing, and a strobe light source is coupled with the fiber optic lines. An image processor is coupled with the image viewer. With this structure, the condition of a rotating part can be detected without stopping the part.

An authentication token that comprises a flexible solar cell array, a display, a processor, and a memory disposed in communication with the processor. Wherein the processor is configured to receive a signal from the flexible solar cell array, and, if the authentication token has been activated, compute a one-time passcode, and send the one-time passcode to the display. A device for communicating with the authentication token comprises a slot for receiving the authentication token; an optical character reader for recognizing characters on the display of the authentication token, and a hi-intensity strobe light for sending light pulses to the flexible solar cell array.

An apparatus and method for tracking aircraft wingtip position during taxi operations to prevent wingtip ground incursion. A patterned illumination source is attached proximal the wingtips to project a readily discernable target pattern in the direction of taxi travel. At least a portion of the target pattern is reflected off of any obstructions that lie in the straight-line direction of travel, such that the pilot can maneuver to avoid striking the obstruction. By way of example, the patterned illumination source comprises a laser module positioned with the navigation and/or strobe light of the aircraft. The device may be retrofitted to existing aircraft without additional wiring with the control of activation being selectable via power cycling of existing aircraft lighting controls. One aspect of the invention provides a tip tracking module bulb that may be retrofitted into existing light sockets to simplify system installation.

An electronic light source system is employed to create a flame-less tracer for a munitions projectile. The electronic light source system may be positioned in various locations and combinations of locations on a projectile (e.g., front, back, side, etc.) to enhance visibility of the projectile during flight. The electronic light source system provides a light source on the projectile that is visible to an observer at various viewing angles throughout the projectile flight without the environmental or safety issues presented by tracers using pyrotechnic materials. After assembly, the present system is encapsulated in glass or clear plastic to G-harden the present system, enabling the present system to sustain the large loads and stresses induced by gun launch. The present system may comprise a variety of light sources such as, for example, lasers, high output light-emitting diodes (LEDs), strobe lights, etc. The present system is capable of flashing the light sources at a variety of frequencies (e.g., 5 Hz, 20 Hz, etc.) to further attract the human eye. In addition, the present system presents the substantial benefit of being able to project light at various wavelengths outside the visible spectrum.
