Publication number: 20170061168Abstract: Disclosed is a self-test device and method for assessing the functional performance of a reader device that is configured to interface with a wireless sensor. The self-test device may be configured to analyze the accuracy of a signal transmitted from the reader device or the accuracy of a signal received by the reader device. In one embodiment, the reader device may be configured to engage the self-test device to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the self-test device to output a resonant signal. The self-test device may receive the transmit signal from the reader and evaluate it against predetermined values. The evaluated signals may be used to assess the accuracy of the transmit signal of the reader device to identify potential calibration issues and initiate remedial action by an automated system or human intervention if needed.Type: ApplicationFiled: September 2, 2015Publication date: March 2, 2017Inventors: Balamurugan Sundaram, Michael Nagy, Douglas Nielsen, Suresh Sundaram

Publication number: 20170055048Abstract: A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits an excitation pulse to cause the wireless sensor to generate a ring signal. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. The reader uses an ambient reading or other information to select a subset of the possible ring signal frequencies, and tunes or adjusts its circuits and algorithms to focus on that subset.Type: ApplicationFiled: November 7, 2016Publication date: February 23, 2017Inventors: Michael Nagy, Harry D. Rowland, Balamurugan Sundaram

Patent number: 8493187Abstract: A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits a narrowband, fixed frequency excitation pulse to cause the wireless sensor to generate a ring signal. The ring signal corresponds to the value of the physical parameter being sensed. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. The low power, simple circuitry required to generate the excitation pulse allows the reader to be a small, battery operated unit. Alternative methods of frequency determination are also disclosed.Type: GrantFiled: March 19, 2010Date of Patent: July 23, 2013Assignee: Endotronix, Inc.Inventors: Harry D.

Publication number: 20060004536Abstract: The present invention systems and methods facilitate configuration of functional components included in a remotely located integrated circuit die. In one exemplary implementation, a die functional component reconfiguration request process is engaged in wherein a system requests a reconfiguration code from a remote centralized resource. A reconfiguration code production process is executed in which a request for a reconfiguration code and a permission indicator are received, validity of permission indicator is analyzed, and a reconfiguration code is provided if the permission indicator is valid. A die functional component configuration process is performed on the die when an appropriate reconfiguration code is received by the die. The functional component configuration process includes directing alteration of a functional component configuration. Workflow is diverted from disabled functional components to enabled functional components.Type: ApplicationFiled: December 18, 2003Publication date: January 5, 2006Inventors: Michael Diamond, John Montrym, James Van Dyke, Michael Nagy, Sean Treichler

Publication number: 20050261863Abstract: The present invention systems and methods enable configuration of functional components in integrated circuits. A present invention system and method can flexibly change the operational characteristics of functional components in an integrated circuit die based upon a variety of factors, including if the die has a defective component. An indication of the defective functional component identification is received. A determination is made if the defective functional component is one of a plurality of similar functional components that can provide the same functionality. The other similar components can be examined to determine if they are parallel components to the defective functional component. The defective functional component is disabled if it is one of the plurality of similar functional components and another component can handle the workflow that would otherwise be assigned to the defective component. Workflow is diverted from the disabled component to other similar functional components.Type: ApplicationFiled: December 18, 2003Publication date: November 24, 2005Inventors: James Van Dyke, John Montrym, Michael Nagy, Sean Treichler

Publication number: 20050251761Abstract: The present invention systems and methods enable configuration of functional components in integrated circuits. A present invention system and method can flexibly change the operational characteristics of functional components in an integrated circuit die based upon a variety of factors. In one embodiment, manufacturing yields, compatibility characteristics, performance requirements, and system health (e.g., the number of components operating properly) are factored into changes to the operational characteristics of functional components. In one exemplary implementation, the changes to operational characteristics of a functional component are coordinated with changes to other functional components. Workflow scheduling and distribution is also adjusted based upon the changes to the operational characteristics of the functional components. For example, a functional component configuration controller changes the operational characteristics settings and provides an indication to a workflow distribution component.Type: ApplicationFiled: December 18, 2003Publication date: November 10, 2005Inventors: Michael Diamond, John Montrym, James Van Dyke, Michael Nagy, Sean Treichler
