Patent number: 11353567Abstract: Sensors may employ a constant false alarm rate (CFAR) screening process in combination with edge-based echo detection. In one illustrative embodiment, a sensor controller includes: a transmitter, a receiver, and a processing circuit coupled to the transmitter and to the receiver. The transmitter drives a piezoelectric element to generate acoustic bursts. The receiver senses a response of the piezoelectric element to echoes of each acoustic burst. The processing circuit is operable to apply echo-detection processing to the response by: determining a derivative signal from the response; and detecting an echo based at least in part on a peak in the derivative signal indicating a rising and/or falling edge in the response. Signaling to the electronic control unit may specify a time of flight associated with each edge.Type: GrantFiled: August 2, 2019Date of Patent: June 7, 2022Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Marek Hustava, Jiri Kantor

Publication number: 20220146653Abstract: Disclosed sensors, sensor controllers, and sensor control methods enhance transducer performance using a model-based equalization method that can be performed in the field. One illustrative method for operating a piezoelectric-based sensor includes: sensing a response of a piezoelectric transducer as a function of frequency; deriving parameter values of an equivalent circuit for the piezoelectric transducer from the response; using a squared magnitude of the equivalent circuit's transfer function to determine a system level selectivity; and adapting at least one operating parameter of the sensor based on the system level selectivity. One illustrative controller for a piezoelectric transducer includes: a transmitter that drives the piezoelectric transducer; a receiver that senses a response of the piezoelectric transducer; and a processing circuit coupled to the transmitter and to the receiver to calibrate the transducer using the foregoing method.Type: ApplicationFiled: November 9, 2021Publication date: May 12, 2022Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Marek HUSTAVA, Jiri KANTOR, Tomas SUCHY

Patent number: 11163048Abstract: Various sensors, sensor controllers, and sensor control methods are provided with model-based sideband balancing. In one illustrative embodiment, a controller for a piezoelectric transducer includes a transmitter, a receiver, and a processing circuit coupled to the transmitter and receiver. The processing circuit performs calibration and echo detection, the calibration including: sensing the piezoelectric transducer's phase response as a function of frequency; deriving equivalent circuit parameters for the piezoelectric transducer from the phase response; and determining a sideband imbalance based on one or more of the equivalent circuit parameters. Once the sideband imbalance is identified, the processing circuit may perform echo-detection processing that accounts for the sideband imbalance.Type: GrantFiled: December 23, 2019Date of Patent: November 2, 2021Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Tomas Suchy, Jiri Kantor, Marek Hustava

Patent number: 7653679Abstract: A message brokering mechanism for performing a recovery operation in a transaction processing system including first and second stages operable to exchange message requests and responses. The first stage may receive a message request from a message source and may check whether the message request is a special message request. This may be by way of checking if a recovery attribute of the message request is set. A normal message request may have a recovery attribute that is not set. If the message request is a special message request, it may be dispatched to the second stage. If the message request is a normal message request, it may be dispatched to the second stage if the normal message request is not a repeat normal message request.Type: GrantFiled: August 15, 2002Date of Patent: January 26, 2010Assignee: Sun Microsystems, Inc.Inventors: Jiri Kantor, Andrew Patterson, Paul Bevis, David Turvey, Craig McMillan, Andrew Sadler

Patent number: 7523164Abstract: A message brokering mechanism for a transaction processing system may include first and second stages operable to exchange message requests and responses. The first stage may be operable to receive a message request from a message source and to check whether there is an existing first stage response to the message request. In some embodiments, if there is an existing first stage response, the first stage may dispatch the existing first stage response to the message source.Type: GrantFiled: August 15, 2002Date of Patent: April 21, 2009Assignee: Sun Microsystems, Inc.Inventors: Jiri Kantor, Andrew Patterson, Paul Bevis, David Turvey, Craig McMillan, Andrew Sadler

Publication number: 20030126229Abstract: Disclosed is a message brokering mechanism (120, 220) for performing a recovery operation in a transaction processing system (100, 200), comprising first and second stages (221, 222) operable to exchange message requests and responses. The first stage (221) is operable to receive a message request from a message source (110, 210) and to check whether the message request is a special message request. This may be by way of checking if a recovery attribute of the message request is set. A normal message request may have a recovery attribute that is not set. If the message request is a special message request, it can be dispatched to the second stage. If the message request is a normal message request, it may be dispatched to the second stage only if the normal message request is not a repeat normal message request.Type: ApplicationFiled: August 15, 2002Publication date: July 3, 2003Inventors: Jiri Kantor, Andrew Patterson, Paul Bevis, David Turvey, Craig McMillan, Andrew Sadler
