Abstract: An optical fluid tester device for testing a fluid sample in an ampoule includes an ampoule cradle, a radiation source, a radiation detector and an analyzer. The ampoule cradle supports the ampoule. The ampoule with the fluid sample serves as a lens whose focal properties are dependent on the index of refraction of the fluid sample. The radiation source irradiates the ampoule. The radiation detector is located opposite the radiation source so that the ampoule, when supported by the ampoule cradle, lies between the radiation source and the radiation detector. The detector serves to detect the intensity of the incident radiation. The analyzer verifies the composition of the fluid sample based on the detected intensity, which is dependent on the focal properties of the ampoule and is, therefore, indicative of the composition of the fluid sample.

Abstract: Fluid level detector device and method are disclosed, for determining the height level of one or more immiscible fluids in a vessel. The device includes at least one optical set-up including a light source for generating a beam of light of predetermined width and optical characteristics, the light beam arranged to be directed into the fluid so as to cause refraction of the light beam, dependent on the index of refraction of the fluid, the light beam covering a predetermined detection region. A photosensitive detector is provided capable of generating a signal corresponding to at least one optical characteristic of the light beam after passing the fluid. An interpreter is provided for receiving the signal, interpreting the signal and indicating the height level of the fluid.

Abstract: Embodiments of the present invention provide a shooting range simulator system and method able to monitor the aiming history of a shooter. The method may include determining an aimed-at position of one or more aiming devices on a target screen by selectively illuminating positions on the screen according to a predefined scheme; detecting scattered light from the illuminated position from one or more viewing angles; and deriving coordinates of the aimed-at position based on the timing of the detection relative to the scanning scheme. The system may include a scanner to selectively illuminate screen elements and a processing center to determine an aimed-at position on the screen. Additional features are described and claimed.

Abstract: A music player device comprising a playback device for playing music piece, a memory unit for storing a database comprising a list of rhythm values attributed to each music piece corresponding to the rhythm of that piece; and a controller for choosing a workout program comprising at least one of a series of workout sessions each selected to match a desired rhythm and playing at least one of a series of music pieces, that are selected by their rhythm value, to correspond to the desired rhythm of the workout sessions.

Abstract: A micromirror array device comprising at least two of a plurality of zones of separately controllable tiltable reflecting elements, each of the tiltable reflecting elements of a zone being capable of tilting about an axis of predetermined tilt orientation associated with the zone between a first reflecting position reflecting an incident beam to a predetermined first direction (on direction), and a second reflecting position reflecting the incident beam to a predetermined second direction (off direction), each of the zones having a predetermined tilt orientation for all reflecting elements in that zone, that is different from the tilt orientation of at least one other zone of the zones.

Abstract: A method and apparatus for displaying composite images, as viewed from a relatively stationary eye point, including a moving target image of relatively small field-of-view overlaid on a background image of relatively large field-of-view, by generating a background image video stream of image data for the background image; updating the background image video stream at a zero or low data update-rate; generating a target image video stream of image data for the target image; updating the target image video stream at a relatively high data update-rate; combining the background and target image video streams to produce a combined video stream; and feeding the combined video stream to a display system for displaying the composite images.

Abstract: An improved method of tracking a camera in dynamic chroma-keying of the type in which a foreground object is photographed against a multicolored chroma-key screen. The multicolor patterns are created by projection on a monochrome screen, for example by projecting light through a mask on a screen colored with the chroma-key color. The projection of multiple patterns can emulate the use of a single pattern having multiple levels of detail, and can enable lateral tracking of the camera. Sequentially projecting known transformations (for example, rotations) of a pattern adds an extra degree of freedom which further enhances the accuracy of the method.

Abstract: A method of coordinating communications among several moving participants that have several communications channels available to them. Each participant is provided with a mechanism for continuously determining its own location and with a table of the locations of the other participants. Each participant selects the channel to use to communicate to each other participant, based on its own determined location and the tabulated locations of the other participants. Periodically, the participants broadcast their own locations to each other.

Abstract: A method and apparatus is described where the coordinates of the main objects of a video studio set are placed in a computer and special markings are projected or screened on the floor or on the studio walls in real time. This enables an actor to easily find his way around the set, and to focus his gaze on the virtual objects appearing in or disappearing from the studio. The present invention gives the actor the timings for various events taking place in the studio. The special markings are completely invisible to the camera and to the home viewers because they are only active during virtual blanks of the camera such as the vertical blanking interval or the horizontal blanking interval in an NTSC, PAL, SECAM or other video signal format.

Abstract: A video system is described which creates a virtual shadow of a foreground object filmed in front of a blue screen with a main video camera. The virtual shadow is created using a second video camera located as a virtual light source. Images from both cameras are processed by a chroma keyer to separate the foreground object. The video image from the second camera is processed to create the virtual shadow and both video images are combined with background image. Object location and actor prompting systems are described.
