Abstract: The Email Value Indicator comprises a computer implemented system and method for indicating the value of an email message. The system and method comprise collecting message values assigned to the email message; calculating a composite message value based on the collected message values; and inserting the composite message value into the email message. In additional embodiments, the system and method further comprises the steps of displaying the composite message value in an email reader, sorting the email message based on the composite message value, and calculating the composite message value based on selected message values.

Abstract: A method for image tracking includes receiving a plurality of images of a first object at points along a predetermined route at least two spaced apart cameras including a first camera and a second camera, calibrating the cameras based on the received images of the first object and the predetermined route, receiving at least one image of a second object at the calibrated cameras, and determining a position of the second object based on one of the received images of the second object at the first camera. A method of image tracking includes associating at least one object with a unique identifier and receiving a plurality of images of the object moving in a field of view of at least two spaced apart cameras. The method further includes determining a position of the object based on the unique identifier and generating a position information based on the determination.

Abstract: The “Idiom Identifier” converts an original text document to a “neutral” form containing no punctuation, no capital letters, and having only a single space between each word. Neutral form text also removes hidden markup such as line breaks, paragraph breaks or page breaks. The Idiom Identifier performs an enhanced text search to locate idioms listed in a library file. The Idiom Identifier marks each identified idiom in a marked-up copy of the original text document. A reader can click on the marked-up idiom to see a definition of the idiom.

Abstract: Vehicular situational awareness systems, method and arrangements are disclosed herein. In one embodiment digitized video can be acquired by a camera on a vehicle, and utilizing pixel differentiation at least one area of interest in the digitized video can be identified. The area of interest could be, for example, a group of pixels that represent another vehicle, a sign etc. Attribute information for the area of interest, such as size, movement etc. of an object, can be acquired and then it can be determined if the attribute information is significant enough or important enough to set an alarm condition and notify the driver.

Abstract: A shearing interferometer measures the aberration of a lens by passing a beam through the lens, splitting the beam into plural beams with a slightly wedged plate and causing interference between the wavefronts of the beams. The front and rear optical surfaces of the wedged plate are coated with reflective thin films each having a specific reflectance and transmittance.

Abstract: A time series signal multichannel frequency analyzer comprises a Fourier transform lens, a liquid crystal panel disposed at the front focal plane of the Fourier transform lens, means for inputting a time signal from a different signal source to each scanning line of the liquid crystal panel, observation means disposed at the rear focal plane of the Fourier transform lens, and a cylindrical lens disposed between the Fourier transform lens and an observation plane of the observation means.

Abstract: A high stability interferometer is capable of continuous measurement of small changes in the refractive index of a sample. The interferometer has a diffraction grating placed to be movable sideways or radially, and diffract laser light into beams which include +1, -1 and zero order beams. The diffraction grating is in the input plane of a Fourier Transform lens. The beams are brought to a focus in the output plane of the lens and are reflected back towards the lens by a mirror placed in the transform plane of the lens. The sample whose refractive index is to be measured is placed in the path of the +1 or -1 order beam, between the diffraction grating and the mirror.

Abstract: Optical spatial phase modulation is achieved by positioning a liquid crystal layer in the path of a light beam to be modulated and controlling the spatial distribution of refractive index of the liquid crystal layer by controlling the spatial distribution of the electrical field generated across the liquid crystal layer.
