Patent number: 10699186Abstract: Systems and methods are provided for determining an order of execution of a neural network. For instance, data indicative of a neural network and data indicative of an amount of available memory in a constrained memory space can be obtained. The neural network can include a plurality of operators. An order of execution associated with the neural network can then be determined. The order of execution specifies an order in which to execute each of the plurality of operators. The order of execution is determined based at least in part on the available memory in the constrained memory space. In particular, one or more graph search algorithms can be performed on a graph that is representative of the neural network to obtain the order of execution.Type: GrantFiled: December 2, 2015Date of Patent: June 30, 2020Assignee: Google LLCInventors: Warren Craddock, Fabien Viger

Patent number: 9250714Abstract: Described herein are optical proximity detectors, methods for use therewith, and systems including an optical proximity detector. Such optical proximity detectors include an analog front-end and a digital back-end. In certain embodiments, the digital back-end includes a dynamic gain and phase offset corrector, a cross-talk corrector, a phase and magnitude calculator, and a static phase offset corrector. The dynamic gain and phase offset corrector corrects for dynamic variations in gain and phase offset of the analog front-end due to changes in temperature and/or operating voltage levels. The crosstalk corrector corrects for electrical and/or optical crosstalk associated with the analog front-end. The phase and magnitude calculator calculates phase and magnitude values in dependence on the corrected versions of digital in-phase and quadrature-phase signals received from the analog front-end. The static phase offset corrector corrects for a static phase offset of the optical proximity detector.Type: GrantFiled: September 24, 2014Date of Patent: February 2, 2016Assignee: INTERSIL AMERICAS LLCInventors: Itaru Hiromi, Philip V.

Patent number: 8558955Abstract: Provided herein are methods and systems that provide automatic compensation for frequency attenuation of a video signal transmitted over a cable. In accordance with an embodiment, a system includes an equalizer and a compensation controller. The equalizer receives a video signal that was transmitted over a cable, provides compensation for frequency attenuation that occurred during the transmission over the cable, and outputs a compensated video signal. The compensation controller automatically adjusts the compensation provided by the equalizer based on comparisons of one or more portions of the compensated video signal to one or more reference voltage levels. The compensating is selectively locked and reset in response to specific conditions being detected, e.g., a locking condition and a reset condition.Type: GrantFiled: October 20, 2009Date of Patent: October 15, 2013Assignee: Intersil Americas Inc.Inventors: David W. Ritter, Warren Craddock, Robert David Zucker

Patent number: 8341689Abstract: Systems and methods to provide automatic compensation for frequency attenuation of a video signal transmitted over a cable are provided. Frequency compensation is applied to a received video signal that was transmitted over the cable to thereby produce a compensated video signal. A shape of a horizontal sync portion of the compensated video signal is analyzed. The frequency compensation is automatically adjusted based on the shape of the horizontal sync portion of the compensated video signal. This abstract is not intended to be a complete description of the various embodiments of the present invention.Type: GrantFiled: October 21, 2005Date of Patent: December 25, 2012Assignee: Intersil Americas Inc.Inventors: Warren Craddock, Elias Andrikopoulos

Publication number: 20110180709Abstract: A system and method for identifying a position of a moving object, utilizing a serial chain of sensors is provided. The serial chain reduces the power needed for the motion detection system, allowing implementation of the motion detection system on a low-power computing device, such as a microcontroller. The serial chain can provide automatic address assignment without dedicated pins. The serial chain can also provide automatic sequencing of access to a shared LED. The serial chain can also provide automatic time correlation of data from multiple sensors in the motion detection system.Type: ApplicationFiled: January 25, 2011Publication date: July 28, 2011Applicant: INTERSIL AMERICAS INC.Inventors: Warren Craddock, David W. Ritter, Philip Golden

Publication number: 20110182519Abstract: A system and method for identifying a position of a moving object, utilizing sensors arranged in any arbitrary configuration, is provided. A pre-processing method is applied to permit implementation on a low power computing device, such as a microcontroller. The preprocessing creates a set of training data corresponding to different gestures, based on different positions of moving objects. Accordingly, utilizing the training data, different types of gestures can be classified by comparing a sensed signal to the set of training gestures.Type: ApplicationFiled: January 25, 2011Publication date: July 28, 2011Applicant: INTERSIL AMERICAS INC.Inventors: Warren Craddock, David W.
