Patent number: 9197934Abstract: A system includes a primary functionality and a backup functionality for the primary functionality. A measurement circuit measures operational parameter values of the primary functionality. A fault detection circuit determines a level of equivalence between the operation of the primary functionality and a reference functionality based on a weighted comparison of the measured operational parameter values of the primary functionality to corresponding reference operational parameter values for the reference functionality If the equivalence determination fails to find equivalence, the fault detection circuit signals a fault in the primary functionality and activates the backup functionality.Type: GrantFiled: May 17, 2012Date of Patent: November 24, 2015Assignee: STMicroelectronics, Inc.Inventor: Steven Srebranig

Patent number: 8856597Abstract: A validation system includes a test block that operates to apply a set of inputs to a system under test, such as a test system or an executable test algorithm, and receive from said system under test a first set of outputs produced by operation of the system under test in response to application of the set of inputs. The first set of outputs, as well as a second set of outputs reflecting output produced by operation of a reference system or executable reference algorithm in response to application of the same set of inputs, is processed to make a validation determination. A validation processing block compares the first and second sets of outputs to validate the system under test as an equivalent to the reference system.Type: GrantFiled: May 24, 2012Date of Patent: October 7, 2014Assignee: STMicroelectronics, Inc.Inventors: Steven Srebranig, Paul A.

Patent number: 8666911Abstract: An apparatus and method are disclosed for a measurement system that reports as a measurement result a confidence interval associated with a histogram bin into which a measurement value falls. The confidence interval is calculated from a subset of training values that also fall within the histogram bin. A training process may be performed in which a plurality of training values is obtained and a mean and standard deviation of the values determined. A plurality of histogram bins are defined from the mean and standard deviation and, for the subsets of training values that fall into each bin, confidence intervals calculated. A need to perform the training process may be determined from a plurality of measured values.Type: GrantFiled: November 30, 2009Date of Patent: March 4, 2014Assignee: STMicroelectronics, Inc.Inventor: Steven Srebranig

Patent number: 8543851Abstract: A system and method for optimizing power distribution in a closed system. In an electronic device, one may apply a plurality of driving algorithms for components that provide different variations functionality. Thus, each component may be operated according to one of several different algorithms depending on the level and manner of functionality needed. In this manner, the overall system may be optimized for any number of operating modes such that each component may conserve electrical power usage while still providing the needed functionality for specific components during each operating mode. Such an optimization assessment may be a function of an economic model applied to the system whereby functionality and components are assigned specific values and costs based on the required functionality for any given task. Thus, the amount of power available may be allocated in an efficient manner based on a cost-benefit analysis.Type: GrantFiled: December 29, 2010Date of Patent: September 24, 2013Assignee: STMicroelectronics, Inc.Inventors: Steven Srebranig, Mohammed I Alhroub

Patent number: 8422392Abstract: A system and method for optimal allocation of bandwidth in a multichannel transmission channel. In an embodiment, a system may allocate a specific amount of bandwidth in the transmission channel in order to maximize the value of the data that is transmitted on a per-channel basis. Typically, a transmission channel has enough bandwidth to accommodate the minimum bandwidth for all data across all channels. The excess bandwidth may be allocated in an optimal manner so as to provide additional bandwidth for the most valuable channels. The maximum allocation of bandwidth is a point in which allocating additional bandwidth to a channel does not yield any additional value. Such an allocation may be accomplished using an iterative analysis of the available bandwidth and a microeconomic-based analysis of the subjective value of each channel.Type: GrantFiled: January 26, 2011Date of Patent: April 16, 2013Assignee: STMicroelectronics, Inc.Inventor: Steven Srebranig
