Patent number: 6553080Abstract: A communication system and method for continuous phase modulation providing for transmission of a phase-modulated carrier having a phaseform representative of concurrently transmitted symbols. The phaseform of the phase-modulated signal is a sum of shift bi-orthogonal functions, each term in that sum being weighted by one of the overlapping symbols. The communication system and method provide full-response demodulation for the recovery of a particular symbol from among the concurrently transmitted symbols by selecting a receiving filter function shift bi-orthogonal to the transmitter filter function corresponding to the particular symbol. The communication system and method then provide for nulling, by integration over a time interval during which the particular symbol is transmitted, those transmitter filter functions that do not correspond to the particular symbol. This results in the separation of the particular symbol from the other concurrently transmitted symbols.Type: GrantFiled: January 3, 2001Date of Patent: April 22, 2003Assignee: FutureWave, Inc.Inventors: Howard L. Resnikoff, Mark Tigerman

Patent number: 6244703Abstract: A method for calibrating an electronic vision device, such as a personal glare reduction device, having a darkened spot in its field of view includes the steps of fixing the lens coordinates of the darkened spot to correspond to a calibration site in the field of view, and moving the glare reduction device to place the darkened spot in line with the glare source. A processor evaluates a correction angle on the basis of the new direction to the glare source, as measured by a directional light sensor on the glare reduction device. The apparatus of the invention includes a controller that includes the processor, a memory, a light sensor, and a user interface element.Type: GrantFiled: March 15, 2000Date of Patent: June 12, 2001Inventors: Nathaniel Resnikoff, Howard L.

Patent number: 5583952Abstract: An apparatus for decompressing an image that has been compressed by an image compression system in which the image is first repetitively filtered in one direction to produce a series of sub-images which are then repetitively filtered in a second direction to produce an image representation having a plurality of sub-images in which each sub-image has a different spatial frequency content is disclosed. The decompression apparatus reverses the filtering process to recover the original image.Type: GrantFiled: January 4, 1993Date of Patent: December 10, 1996Assignee: Aware, Inc.Inventors: Howard L. Resnikoff, William Zettler, Jr.

Patent number: 5359627Abstract: A channel coding system comprising apparatuses and methods for encoding and decoding signals is disclosed. The system utilizes an orthonormal basis of numerical sequences for coding an input signal. The orthonormal bases reduce channel interference. A method for generating long basis sequences from the product of shorter sequences is also disclosed.Type: GrantFiled: July 1, 1993Date of Patent: October 25, 1994Assignee: Aware, Inc.Inventor: Howard L. Resnikoff

Patent number: 5148498Abstract: An image coding apparatus and method are disclosed. The method and apparatus are applicable to coding any array of arbitrary dimension. The apparatus utilizes FIR filters which generate three or more sets of coefficients from linear arrays generated from the array being coded. Each set of coefficients represents spatial frequency information of different frequencies. The filters utilize coefficient sets which are preferrably orthogonal.Type: GrantFiled: August 1, 1990Date of Patent: September 15, 1992Assignee: Aware, Inc.Inventors: Howard L. Resnikoff, David Pollen, David C. P. Linden, Wayne M. Lawton

Patent number: 5101446Abstract: A method for coding an image or other two-dimensional data array to provide a sequence of images having differing spatial frequency content is disclosed. The method generates the output images by taking weighted sums of the pixels in the input image. The weights are sets of two-dimensional irreducible scaling and wavelet coefficients.Type: GrantFiled: May 31, 1990Date of Patent: March 31, 1992Assignee: Aware, Inc.Inventors: Howard L. Resnikoff, David Pollen, David C. P. Linden

Patent number: 5081645Abstract: A system comprising apparatuses and methods for encoding and decoding spread spectrum signals is disclosed. Signals are encoded by modulating numerical sequences selected from an orthonormal basis of numerical sequences to provide channel coding. The modulated sequences are then combined to form an encoded signal. Because of the orthonormal character of the sequences, the encoded signal may be easily decoded using a matched filter. A method for generating long sequences from the product of shorter sequences is also disclosed.Type: GrantFiled: August 6, 1990Date of Patent: January 14, 1992Assignee: Aware, Inc.Inventors: Howard L.

Patent number: 5068911Abstract: An improved image compression system is disclosed in which the image is first repetitively filtered in one direction to produce a series of sub-images. These sub-images are then repetitively filtered in a second image to produce an image representation having a plurality of sub-images in which each sub-image has a different frequency content.Type: GrantFiled: February 9, 1990Date of Patent: November 26, 1991Assignee: Aware, Inc.Inventors: Howard L.

Patent number: 4904073Abstract: A multiple mirror reflective surface for use in a multiple mirror telescope in which the objective surface of telescope is tiled with substantially identical planar mirrors having irregular boundaries and a mirror for use therein. The mirrors are groupable into groups of seven, one of which is bounded symmetrically by the other six, each mirror having an approximately fractal peripheral boundary such that each group of seven mirrors has a boundary shape which is approximately geometrically similar to that of the mirrors forming the group. The mirrors of such an array have their centers on a hexagonal lattice of points in the objective surface. In a particular embodiment, the mirrors have shapes which approximate that of a fractal shaped mirror by being defined by a combination of hexagonal shapes. With mirrors of this shape, the multiple mirror telescope experiences less optical aberrations which would otherwise be caused by linear edges of the mirrors, without reducing light gathering power.Type: GrantFiled: August 10, 1988Date of Patent: February 27, 1990Assignee: Aware, Inc.Inventors: Wayne M.

Patent number: 4830482Abstract: An optical device for focusing images on the retinas of the left and right eyes of a human user, containing left and right corrective lenses each having a light receiving surface and first and second lens segments of different focal lengths for focusing near and far objects respectively. The boundary between the first and second segments of each of the lenses extends in the same direction and parallel to the light receiving surface, and the lenses are supported and oriented with respect to the eyes of the user so that the boundary is substantially perpendicular to a line connecting the eyes of the user, and so that each first lens segment occupies a nasal position with respect to the user's eyes and each second lens segment occupies a temporal position with respect to the user's eyes.Type: GrantFiled: August 21, 1987Date of Patent: May 16, 1989Inventor: Howard L.

Patent number: 4574311Abstract: A sensing device for generating an output signal corresponding to an input signal which comprises a substrate, an array of sensor elements for receiving the input signal and transfer members located on the surface of the substrate and interposed between the sensor elements. The sensor elements have their barycenters distributed on the surface of the substrate in a random non-periodic pattern. The transfer members are coupled to the sensor elements and generate the output signal.The sensing device is incorporated in an apparatus which generates an output signal from an input image wherein the output signal is substantially free of detectable aliases. The apparatus includes an image pick-up device for viewing the input image and transmitting radiation to the image sensing device, an analog-to-digital converter for converting the analog signal from a sensing device to a digital signal, a position encoder, an interpolator and a memory means for storing the output of the interpolator.Type: GrantFiled: April 4, 1985Date of Patent: March 4, 1986Assignee: Thinking Machines CorporationInventors: Howard L.
