Abstract: A device for measuring the relative blood flow rates between the right and left hemispheres of the brain utilizing a first sensor adapted to lie in the vicinity of the right ear of a mammalian subject. The first sensor generates a first signal representing the temperature of the right ear. Likewise, a second sensor is adapted to lie in the vicinity of the left ear and measure the temperature of the left ear. A signal is generated by the second sensor representing such temperature measurement. A monitor simultaneously acquires the first and second signals and the quantitative difference between the first and second signals is determined.

Abstract: A distortion analyzer for generating a distortion signal based on an input signal. For example, the distortion signal may be generated by adding a first signal corresponding to the entire spectrum of the input signal to a second signal corresponding to a low-frequency component of the input signal and then subtracting from the result of addition a third signal corresponding to a specific frequency band of the input signal. The effect of polarization mode dispersion that an optical signal experiences as it propagates through an optical transmission fiber may be compensated for at a receiver using a birefringent compensator, in which the distortion analyzer continuously examines the signal outputted by the compensator and supplies the distortion signal to the compensator, which causes the compensator to reduce the effect of such polarization mode dispersion based on the level of the distortion signal.

Abstract: A device for applying stimuli to a subject for therapeutic purposes utilizing an audio source producing a selected audio tone. An audio speaker delivers the audio stimulus to the left and right ears of the subject in an alternating manner, such that the sounds may be heard in either of the ears or may be heard in both of the ears in sequential fashion. Visual or tactile stimuli may be delivered to a subject singularly or simultaneously with the audio stimulus.

Abstract: The present invention provides a process for detecting and enumerating Campylobacter jejuni in an environmental sample. The present invention further provides a process which can distinguish antibiotic resistant strains of Campylobacter jejuni from wild-type strains, in particular, antibiotic-resistant strains resistant to high levels of ciprofloxacin. Both processes use PCR primers which flank a target sequence unique to Campylobacter jejuni in combination with one or more dual-labeled oligonucleotide probes complementary to the target sequence wherein the dual-labeled probes enable detection of PCR amplification by fluorescence detection means.

Abstract: The effect of polarization mode dispersion that an optical signal experiences as it propagates through an optical transmission fiber is compensated for at a receiver using a birefringent compensator, in which a distortion analyzer repeatedly examines the signal outputted by the compensator and causes the compensator to reduce the effect of such polarization mode dispersion based on the results of such examination.

Abstract: A method of decoding a quadrature encoded signal where position tracking is implemented which decouples the position calculations from the encoder edges. In one embodiment of the present invention, a uni-directional pulse accumulator is used to count encoder edges, and a periodic interrupt timer is used to update the position information, where interrupts are generated independent from encoder edges. At slow speeds, the mode switches to monitor each encoder edge to check for direction reversal without requiring position information. This decodes bi-directional quadrature position information using a uni-directional counter and a count compensation method for resolving changes in direction.

Abstract: A device for stimulating eye movement in a subject utilizing a hand held screen which is capable of displaying a multiplicity of visual elements. A power source illuminates the multiplicity of visual elements according to a particular selection of a visual pattern. Once selected, the visual pattern is executed and displayed by sequentially illuminating adjacent visual elements constituting groups of visual elements. The illuminated element form a cyclic pattern for scanning by the subject.

Abstract: The effect of polarization mode dispersion that an optical signal experiences as it propagates through an optical transmission fiber is compensated for at a receiver using a birefringent compensator, in which the compensator automatically and adaptively generates a level of differential time delay that substantially equals the differential time delay that the optical signal experiences, but of different sign, and, therefore, essentially cancels out the undesired delay.

Abstract: The propagation of very high frequency signals, e.g., 8 to 10 GHz, via a path printed on a printed wiring board is enhanced by arranging the path so that it simulates a high-quality transmission path at very high frequencies. The path comprises a conventional lead and a series of microstrips, in which the design of the microstrips is optimized to (a) minimize insertion loss and group delay distortion, (b) maximize return loss, and (c) minimize pulse distortion.

Abstract: A pulse width modulator (PWM) system (100) detects several load current conditions to completely correct for the distortion caused by deadtime insertion when driving an inverter-fed inductive load, such as a three-phase AC motor. The system includes an inexpensive voltage sensor (140) which senses the output voltage at the end of each successive dead time interval in which neither a pullup transistor (51) nor a pulldown transistor (52) is driving. The system (100) includes a programmable PWM (125), two storage elements (131,132) such as D-type flip flops, and a memory-mapped register (133). The register stores the output of the flip-flops to indicate a near-zero load current condition. When it detects this condition, the system (100) changes the duty cycle of the PWM output signals to yield output voltages and currents which more closely approximate a sine wave. The system (100) is particularly useful as part of a low-cost microcontroller (120).

Abstract: A common application of X-ray fluoroscopy is in monitoring the location of a catheter inside a body. Such catheters may be used for balloon angioplasty, laser ablation, or like procedures that are now often used in place of traditional invasive surgery. Reliable and fast determination of the tip location from the fluoro images using the digital image processing technique is required. The present invention relates to a method for tracking a catheter probe or similar object during a fluoroscopic procedure as may be utilized, for example, in conjunction with apparatus and methods that confine full X-ray dosage to a central area, compensating for the reduced X-ray dosage in the peripheral areas by computer imaging enhancement.

Abstract: A device for inducing saccadic eye movement in a subject utilizing a source of power which activates a multiplicity of visual signaling elements. The visual signaling elements are mounted in a structure such that the elements are placed at a certain level and angle relative to the eye or eyes of the subject. The visual signaling elements are sequentially activated in a back and forth manner.

Abstract: The present invention is a method for locating an edge portion of an aperture in an X-ray filter member having at least one aperture formed therethrough, such that X-rays passing through the at least one aperture remain unattenuated and strike a subject body in a common region and wherein the X-rays passing through the filter member are attenuated and strike the subject body in a pattern that surrounds, and is adjacent to, the common region.

Abstract: The present invention is an apparatus and method for reducing the dosage of X-rays during a fluoroscopic procedure wherein a filter member is used to selectively attenuate the X-ray radiation striking a patient's body. The filter member allows unattenuated X-rays to image an area of interest selected by a physician, thus producing a high intensity, low noise image. However, the areas surrounding the area of interest are imaged with attenuated radiation producing a less intense, more noisy image. A real-time image processing system is used to compensate the image brightness and to potentially filter the compensated region so as to reduce noise. Image quality is thus restored so that a physician can orient the location of a procedure, within a patient's body, and have perspective to the position of area of interest relative to its surroundings.
