Patent number: 10116488Abstract: A system may be provided in which an industrial control network may be discovered and characterized such that useful networking data may be presented to a user and/or monitored for events. By configuring an interrogator device to send a “generic” message to ranges of network locations, presences of devices at particular locations may be determined. The generic message may direct any of numerous devices types to provide a response including multiple parameters. The interrogator may store such parameters in “data records,” and may advantageously send periodic collections of data records, or “data sets,” to a processing manager. The processing manager, in turn, may communicate with one or more data structures to format, enrich and/or monitor the networking data to more conveniently and reliably capture and maintain networks and connected devices.Type: GrantFiled: January 8, 2016Date of Patent: October 30, 2018Assignee: Rockwell Automation Technologies, Inc.Inventors: Joseph M.

Patent number: 9460052Abstract: A mechanism for reconstructing a signal (e.g., an image) based on a vector s, which includes measurements of the signal. The measurements have been acquired using at least a portion of a measurement vector set represented by a matrix H. Each of the measurements corresponds to a respective row of the matrix H. (For example, each of the measurements may correspond to an inner product between the signal and a respective row of the matrix product HD, wherein D is a generalized permutation matrix.) A total-variation primal-dual hybrid gradient (TV-PDHG) algorithm is executed based on data including the matrix H and the vector s, to determine an estimate for the signal. The TV-PDHG algorithm is implemented in fixed-point arithmetic.Type: GrantFiled: December 20, 2013Date of Patent: October 4, 2016Assignee: InView Technology CorporationInventors: Thomas A.

Patent number: 9277139Abstract: A methodology for acquiring measurements of a signal at one or more scales of resolution, including: generating modulation patterns based on a predefined measurement matrix; modulating a received signal with the modulation patterns using the signal modulating array to obtain a modulated signal; and acquiring measurements of intensity of the modulated signal. Each modulation pattern is generated by: (a) selecting a corresponding row of the measurement matrix; (b) reordering elements of the selected row according to a permutation to obtain a reordered row; and (c) transferring the reordered row to the signal modulating array so that elements of the reordered row are mapped onto the signal modulating array. The permutation is defined so that a subset of the modulation patterns are coarse patterns that respect a partition of the signal modulating array into an array of superpixels, each superpixel including a respective group of the signal modulating elements.Type: GrantFiled: January 14, 2014Date of Patent: March 1, 2016Assignee: InView Technology CorporationInventor: Matthew A.

Patent number: 9081731Abstract: If a Hadamard matrix HN of order N=BF is a Kronecker product HFHB of an order F Hadamard matrix and an order B Hadamard matrix, then transformation by HN may be implemented by a fast Hadamard transform at coarse scale followed by fast Hadamard transforms at fine scale. Alternatively, transformation by HN may be achieved by performing order B transforms on columns of a two-dimensional array and order B transforms on rows of the array. As another alternative, transformation by HN may be achieved by computing intermediate values based on linear combinations of input elements and then computing linear combinations of the intermediate values. For compressive signal acquisition, any row of HN may be generated by concatenating selectively modified copies of a corresponding row of HB. Thus, modulation patterns may be generated on the fly.Type: GrantFiled: January 31, 2014Date of Patent: July 14, 2015Assignee: InView Technology CorporationInventors: Matthew A. Herman, Tyler H.

Publication number: 20150116563Abstract: A technique to collect measurements that are adapted to a signal/scene of interest is presented. The measurements are correlations with patterns that serve as modulating waveforms. The patterns correspond respectively to rows of a sensing matrix. The method uses a sensing matrix whose rows are partitioned into blocks. Each block corresponds to a distinct feature or salient property of the scene. For each block, the method collects a number of measurements of the signal/scene based on selected rows of the block, and generates one or more associated statistics for the block based on said measurements. The statistics for the blocks are then analyzed (e.g., sorted) to determine the most important blocks. Subsequent measurements of the signal/scene may be based on rows from those most important blocks. The original measurements and/or the subsequent measurements may then be used in an algorithm to reconstruct the signal/scene.Type: ApplicationFiled: October 29, 2014Publication date: April 30, 2015Applicant: INVIEW TECHNOLOGY CORPORATIONInventors: Matthew A.

Patent number: 8970740Abstract: A mechanism for reconstructing sub-images based on measurement data acquired by an imaging system including an array of light modulating elements and an array of photodetectors. Each sub-image is reconstructed based on samples from a respective photodetector and a respective set of measurement patterns defined on a respective virtual sub-region on the modulating array. Each virtual sub-region is configured to include at least the light modulating elements that are able to send a non-trivial amount of light to the respective photodetector during a pattern application period. The virtual sub-regions overlap because many light modulating elements are capable of sending light to more than one photodetector. Whenever a measurement pattern of one virtual sub-region overlaps the measurement pattern of a neighboring virtual sub-region, the two measurement patterns agree by design. Thus, the measurement patterns for the collection of virtual sub-regions combine to form a pattern on the whole modulating array.Type: GrantFiled: December 13, 2013Date of Patent: March 3, 2015Assignee: In View Technology CorporationInventors: Matthew A.

Publication number: 20140211000Abstract: A mechanism for efficiently loading rows of an N×N transform matrix HN into a signal-modulating array. A row index m(i) that identifies a row r[m(i)] of HN is generated, where i is in the range {0, 1, . . . , L?1}; L is less than or equal to B; and m(i) is in the range {0, 1, . . . , B?1}. HN has the form HN=HFHB. HF is an F×F matrix, and HB is a B×B matrix. denotes the Kronecker product. The row r[m(i)] of HN is generated and loaded into the array. For each k in the range {1, 2, . . . , F?1}, a row r[m(i)+kB] from HN is partially loaded into the array by: loading a first subset of elements of row r[m(i)+kB] that are not currently present in the array, and not loading a second subset of elements of row r[m(i)+kB] that are currently present in the array.Type: ApplicationFiled: January 30, 2014Publication date: July 31, 2014Applicant: InView Technology CorporationInventor: Matthew A.

Patent number: 8760542Abstract: An imaging system and method that captures compressive sensing (CS) measurements of a received light stream, and also obtains samples of background light level (BGLL). The BGLL samples may be used to compensate the CS measurements for variations in the BGLL. The system includes: a light modulator to spatially modulate the received light stream with spatial patterns, and a lens to concentrate the modulated light stream onto a light detector. The samples of BGLL may be obtained in various ways: (a) injecting calibration patterns among the spatial patterns; (b) measuring complementary light reflected by digital micromirrors onto a secondary output path; (c) separating and measuring a portion of light from the optical input path; (d) low-pass filtering the CS measurements; and (e) employing a light power meter with its own separate input path. Also, the CS measurements may be high-pass filtered to attenuate background light variation.Type: GrantFiled: December 19, 2013Date of Patent: June 24, 2014Assignee: InView Technology CorporationInventors: Robert F.
