Publication number: 20120313802Abstract: An approach to signal conversion adapts the signal conversion process, for example, by adapting or configuring signal conversion circuitry, according to inferred characteristics (e.g., probability distribution of value) of a signal being converted. As an example, an analog-to-digital converter (ADC) may be adapted so that its accuracy varies across the range of possible input signal values in such a way that on average the digital signal provides a higher accuracy than had the accuracy remained fixed. In another example, models (and corresponding inference circuitry) of both an input signal process and of a quantization process are used to improve signal conversion accuracy.Type: ApplicationFiled: June 8, 2012Publication date: December 13, 2012Applicant: Analog Devices, Inc.Inventors: Benjamin Vigoda, Jeffrey Bernstein, Martin McCormick

Publication number: 20120194375Abstract: An approach to converting an analog value based on a partition of an input range produces probabilities that the input is found within each of the regions based, for example, on a noisy version of the input. In some examples, iterative and/or pipelined application of comparison circuitry is used to accumulate a set of analog representations of the output probabilities. The circuitry can be adapted or configured according to the characteristics of the degradation (e.g., according to the variance of an additive noise) and/or prior information about the distribution of the clean input (e.g., a distribution over a discrete set of exemplar values, uniformly distributed etc.).Type: ApplicationFiled: April 27, 2011Publication date: August 2, 2012Applicant: Lyric Semiconductor, Inc.Inventors: Benjamin Vigoda, Jeffrey Bernstein, Alexander Alexeyev, William Bradley, Theophane Weber

Publication number: 20100223225Abstract: Some general aspects relate to systems and methods of analog computation using numerical representation with uncertainty. For example, a specification of a group of variables is accepted, with each variable having a set of at least N possible values. The group of variables satisfies a set of one or more constraints, and each variable is specified as a decomposition into a group of constituents, with each constituent having a set of M (e.g., M<N) possible constituent values that can be determined based on the variable values. The method also includes forming a specification for configuring a computing device that implements a network representation of the constraints based on the specification of the group of variables. The network representation includes a first set of nodes corresponding to the groups of constituents, a second set of nodes corresponding to the set of constraints, and interconnections between the first and the second sets of nodes for passing continuous-valued data.Type: ApplicationFiled: March 2, 2010Publication date: September 2, 2010Applicant: Lyric Semiconductor, Inc.Inventors: Benjamin Vigoda, William Bradley, Shawn Hershey, Jeffrey Bernstein

Publication number: 20070103581Abstract: An imaging system includes a line-scan camera (8) having an image line in an planar imaging beam path and a depth of focus. Line forming optics are arranged between at least two arrays of LEDs (4,6) and the image object so as to form two respective illumination stripes in two planar illumination beam paths (5,7). The planar imaging beam path (9) is located between the two or more planar illumination beam paths (5,7). The planar imaging beam path (9) and the two planar illumination beam paths (5,7) preferably intersect proximate to the far depth of focus of the camera. The image line and illumination stripes are parallel across an image area, which may comprise a transport device, such as a conveyor. The non-coplanar planar illumination beam paths provide maximum overlap at the farthest depth of field where illumination is most needed and diverge closer to the camera.Type: ApplicationFiled: October 22, 2004Publication date: May 10, 2007Inventors: John Dwinell, Jeffrey Bernstein

Patent number: 6509547Abstract: This invention results from the realization that a laser can remove the protective layer(s) from the glass or fused silica optical fiber core and cladding more effectively and more reliably than chemical or mechanical means. This invention teaches methods of using laser beams to remove the protective layers of fibers without significantly damaging the optical and mechanical properties of the fiber and without leaving an excessive amount of residual ablation debris on the fiber while providing careful control of the laser energy. This method thereby allows users to safely strip protective layers off sensitive fibers, such as fibers used for fiber Bragg gratings (FBG). This method allows stripping of the protective layers from single fibers and from multi-fiber ribbon cables. It also allows stripping of the protective layers at an end section of the cable or in a middle section (mid-span).Type: GrantFiled: November 28, 2000Date of Patent: January 21, 2003Assignee: Resonetics, Inc.Inventors: Jeffrey Bernstein, James Angell, Pascal Miller

Patent number: 5155594Abstract: A method and apparatus for transmitting a sequence of image frames by encoding interframe error data features the steps of compiling a spatially decomposed image of a background of the sequence of image frames, spatially decomposing a warped image of a previous frame, and spatially decomposing a new input image. The spatially decomposed input image is compared with the spatially decomposed background image and with the spatially decomposed warped image. An error signal defining the spatially decomposed input image is generated based on these comparisons.Type: GrantFiled: May 10, 1991Date of Patent: October 13, 1992Assignee: PictureTel CorporationInventors: Jeffrey Bernstein, Bernd Girod, Xiancheng Yuan

Patent number: 5150209Abstract: A method and apparatus for encoding interframe error data in an image transmission system, and in particular in a motion compensated image transmission system for transmitting a sequence of image frames from a transmitter to a receiver, employ hierarchical entropy coded lattice threshold quantization to increase the data compression of the images being transmitted. The method and apparatus decimate an interframe predicted image data and an uncoded current image data, and apply hierarchical entropy coded lattice threshold quantization encoding to the resulting pyramid data structures. Lossy coding is applied on a level-by-level basis for generating the encoded data representation of the image difference between the predicted image data and the uncoded original image. The method and apparatus are applicable to systems transmitting a sequence of image frames (or other pattern data, such as speech) both with and without motion compensation.Type: GrantFiled: May 10, 1991Date of Patent: September 22, 1992Assignee: PictureTel CorporationInventors: Richard L.
