Abstract: A two-part, high-density card retention system includes a tapered channel in a chassis or housing and a mating wedge that runs the length of the housing, with the lead wedge being cammed towards a flat channel surface by drawing the wedge inwardly and locating the edge of the board to be mounted between the wedge and the opposing straight channel wall. The mounting provides continuous high-pressure contact between the board and the straight channel wall for maximal thermal transfer and robust anti-vibration and anti-shock mounting of the board to the chassis. Because no additional assemblies are mounted to the edge of the board, the boards may be spaced apart by a fine pitch, thus to minimize the size of the module into which the boards are mounted.

Abstract: A multi-tone CW radar (14) is used to project signals from an antenna (22) and to receive returns with the same antenna. The phase differences between the outgoing signals and the returns are analyzed to determine the existence of motion and the range to a moving object (10). A model is made which has range as its major parameter. A waveform associated with the phase difference between outgoing signals and returns for one of the tones is compared to templates produced by the model to determine which has a range that most closely matches. By varying the range parameters, when a match is detected the range to the object can be obtained even if its motion is pseudorandom. If the range is measured with multiple units it is possible to measure the location of the object. This can be done assuming a grid and algorithmically combining the ranges from the units.

Abstract: A wide bandwidth high-power T network tuner obtains its wide bandwidth operation by connecting a fixed capacitor between the input and ground, with the tuner using large, series connected variable capacitors for high power so as to solve the minimum capacitance problem on the higher frequencies, with the input and output matching capacitors being independent one from the other.

Abstract: A wireless device-based system provides location-based services by determining the location of the wireless device and arranges for the service and the payment therefor.

Abstract: A direction finding system is used in which a number of adjacent bands are sequentially measured in fast rotation, with the results from each of the bands being FFT processed to provide amplitude and phase information on all of the signals existing within the band. Upon ascertaining that one wishes to do a direction finding process, one merely accesses the information in the delay memory so that direction finding resources are only allocated to signals of interest and such that one does not have to re-do an FFT upon finding a signal of interest.

Abstract: Picture messages are transmitted to a wireless device with a paging notification that includes the telephone number of a message originator and are used by the message recipient to identify who is sending the message.

Abstract: A targeted search in the form of a fingerprint is generated utilizing audio-visual representations of the search parameters in a master plan so as to present the user with hypothetical vision parameters arrayed in a cascaded manner corresponding to the process individuals use when shopping, with the result being the generation of the parameters that converge on the ultimate fingerprint. In one embodiment a touch screen is utilized to present the hypothetical vision parameters, with the touching of the screen causing a parameter value to be entered into the fingerprint. On-screen vision parameters are kept in the one region of the screen to enable the user to go backwards from any level of the cascade back to any other prior level or even back to the original cascade, such that the cascaded vision parameters are retained on screen.

Abstract: An ultrasonic surveying method includes a network of transceivers adjacent the item to be surveyed to establish a reference plane and locating an array of pingers on the object to be surveyed to establish a survey plane, establishing by ranging from the pingers to the network the location of the survey plane, detecting relative motion between the network and the pingers and correcting survey measurements for the detected motion.

Abstract: An array of three-axis magnetometers used for dynamic magnetic anomaly compensation are located at the corners of a parallelopiped, with pairs of magnetometer outputs used to derive a magnetic anomaly gradient vector used to compensate a compass and/or the output of a gyroscope in an inertial management unit. The system may be used in a neutrally buoyant remotely operated vehicle to permit ascertaining of course and position in the absence of surface control signals.

Abstract: E-field sensors are used to establish a protection zone around a vehicle so as to detect the presence of objects within the protection zone, be they other vehicles or individuals. In one embodiment the direction to the intruding object is established by virtue of the use of pairs of E-field sensors. In a further embodiment the range of the E-field sensors determines the limited protection zone around the vehicle. Because of the limited protection zone, false alarms are greatly reduced.

Abstract: A safe, reliable and rapid system for the detection of nuclear materials within containers includes the use of pulsed high-intensity gamma rays that can penetrate a container and its contents and can be detected outside the container to provide a display in which high-Z material, including lead, uranium, plutonium and other nuclear substances that absorb gamma rays are detected as black regions on the display. In one embodiment, orthogonal pulsed gamma ray beams illuminate the container from two different directions to provide three-dimensional slices from which the existence and location of nuclear threat materials can be ascertained in as little as four seconds for a 40-foot container.

Abstract: A pair of sunglasses is provided with a polarized region in the upper portion of the eyeglass lens and a non-polarized region in the bottom portion of the eyeglass lens so as to permit reading of polarized instruments through the non-polarized region. The two regions may be separated horizontally at the halfway point or below the halfway point such that, by tilting one's head upwardly and looking through the non-polarized region, one can readily read the instruments which would appear black through the polarized region due to the cross-polarization. In one embodiment the polarization level is gradually decreased from the top to the bottom of the lens in a polarization gradient in which there is no polarization at the bottom portion of the lens.

Abstract: A nested cavity embedded loop mode antenna is provided with an ultra wide band response by nesting individual embedded cavity meander line loaded antenna modules, with the meander lines coupled to a ground plane plate either capacitively or directly so as to provide as much as a 27:1 ratio of high frequency to low frequency cutoff. The nested meander line structure is exceptionally compact and eliminates the problem of a null in the antenna radiation pattern perpendicular to the face of the antenna, thus to provide a loop type antenna pattern at all frequencies across which the antenna is to be operated. The use of the nested meander line configuration provides a flush mount for the antenna having a footprint associated with the larger of the meander line cavities and thus the lowest frequency of operation, the nesting precluding the necessity of providing separate side-by-side meander line loaded antennas which would increase the real estate required.

Abstract: A plurality of multi-tone CW radars are used to generate a swath of ranges to a moving object or individual behind a wall or building structure in which the overlap of the range swaths from spaced-apart radars determines the location of the moving object or individual. A histogram of the swath overlaps is used to generate a display of the path of the moving object or individual.

Abstract: A message originator sends a picture or video message to a message center along with caller identifying information. The message is stored in a memory and transmitted to a wireless picture phone, PDA or portable computing device, or stored at the message center in a memory or hard disk drive for later retrieval by a message recipient. The picture or video message may be encoded, encrypted or compressed prior to receipt by the wireless device.

Abstract: A system is provided to improve retinal camera picture quality by providing a user-variable transfer function for each pixel that results in redistributing grayscale values to solve the problem of saturation caused by highly reflective retinal objects. The result is the ability to capture both optic nerve and retina detail in a single picture. The darker retina is brightened to permit observing retinal detail using the redistributed grayscale values, while preserving optic nerve detail. Those pixels experiencing high-intensity reflections are properly exposed to prevent saturation, while outputs of low-intensity pixels associated with the darker regions are intensified, in one embodiment in accordance with an adjustable Bezier curve. The result is that one can obtain retinal details previously flooded out by the reflections from the optic nerve while at the same time offering optic nerve detail.

Abstract: A removable, convenient main drain testing system is provided through the use of a testing device that includes a cap clampable about a drain pipe, an air pressure gauge, a valve and connection to an air compressor. The assembly can be moved from one jobsite to the other with ease and can be transported in a plumber's tool kit without cumbersome apparatus. The test involves injecting compressed air into the system with the valve open, followed by closing of the valve when a test pressure has been obtained and observing the pressure gauge to look for pressure drops indicating leaks. The valve also is useful for the introduction into higher pressure air to ascertain where leaks are occurring should any be observed.

Abstract: A coherent TOA system is provided for rapidly ascertaining the position of a pulse train emitter such as a radar. Techniques are provided to estimate the underlying repetition interval of the emitter and to do the TOA processing knowing which of the particular pulses is being detected at a collector, thus surmounting the effect of gaps in the received pulse stream. The subject system is preferable to conventional time-difference-of-arrival geolocation systems which require that each of the collecting platforms measure the same pulse from the emitter, and also to non-coherent TOA systems whose accuracy is less than that achievable with the subject coherent system for the same amount of data.
