Patent number: 10371799Abstract: A radar apparatus is calibrated while operating in a configuration such that the receiver obtains substantially no reflection from the transmitter. The resultant received signal is written into the compensation signal memory for use during normal operation. The calibration environment is achieved by operating the radar apparatus in a quiet environment or by operating a quieting switch within the radar apparatus to quiet the reflected radar signal.Type: GrantFiled: September 19, 2016Date of Patent: August 6, 2019Assignee: Delta Mobile Systems, IncInventors: James C Graves, Jr., Debra A Jones

Patent number: 9684070Abstract: A radar apparatus measures at least one characteristic of at least one object. A sweep generator generates a sweep signal to modulate an oscillator to generate a varying frequency signal. A transmitter transmits the varying frequency signal as a radar signal. A receiver receives a reflected radar signal to produce a received signal using the varying frequency signal. A compensation signal memory holds a previously stored compensation signal. A compensation circuit compensates the received signal based on the previously stored compensation signal to produce a compensated received signal. A quiet switch quiets the reflected radar signal and determines the previously stored compensation signal, during calibration of the radar apparatus, and the received signal is written into the compensation signal memory. Switched loads can be used to quiet the reflected radar signal. For field calibration, the compensated signal can be adjusted but not necessarily written back into the compensation signal memory.Type: GrantFiled: December 20, 2013Date of Patent: June 20, 2017Assignee: DELTA MOBILE SYSTEMS, INCInventors: Aamir A Abbasi, James C Graves, Jr., Debra A Jones

Patent number: 9448301Abstract: A radar apparatus measures at least one characteristic of at least one object even in a near field. A sweep generator generates a sweep signal to modulate an oscillator to generate a varying frequency signal. A transmitter transmits the varying frequency signal as a radar signal. A receiver receives a reflected radar signal to produce a received signal using the varying frequency signal. A compensation signal memory holds a previously stored compensation signal. A compensation circuit compensates the received signal based on the previously stored compensation signal to produce a compensated received signal. A frequency transformation circuit transforms the compensated received signal to produce a frequency spectrum signal. A peak detector measures the characteristic of the object based on a peak of the frequency spectrum signal. When operating in a calibration mode and the reflected radar signal is quieted, the received signal is written into the compensation signal memory.Type: GrantFiled: December 20, 2013Date of Patent: September 20, 2016Assignee: DELTA MOBILE SYSTEMS, INC.Inventors: Aamir A Abbasi, James C Graves, Jr., Debra A Jones, Michael E Lazar, Ramanujapuram A Raghuvir

Publication number: 20160132053Abstract: A system. The system includes a processor, a memory coupled to the processor, a first wireless communication circuit coupled to the processor. The first wireless communication circuit is configured to receive, from an operations center remotely located with respect to a vehicle, a message comprising an alert concerning a payment event. The system also includes a second wireless communication circuit, distinct from the first wireless communication circuit, coupled to the processor. The second wireless communication circuit is configured to relay the alert to a wireless device.Type: ApplicationFiled: January 15, 2016Publication date: May 12, 2016Applicant: GORDON*HOWARD ASSOCIATES, INC.Inventors: Stanley G. Schwarz, Jeffrey H. Frank, Christopher M. Macheca, Gerald A. Morgan, Franco Chirico, Chris Aron, Mary Sue Karlin, Corey Pelland, Debra A. Jones, James C. Graves, JR.

Publication number: 20100268402Abstract: An onboard starter-interrupt device uses a Personal Area Network (PAN) to facilitate communication between a wireless device (such as a cellular telephone or personal digital assistant (PDA)) and the onboard device (also referred to interchangeably as a vehicle control device or a payment enforcement device) installed on a vehicle. The PAN can be implemented using, for example, the well-known Bluetooth protocol. The use of a PAN avoids the need for a visible keypad or other input device installed in the vehicle. The interface with the PAN also facilitates direct communication (including voice communication) using an existing cell phone. The interface with the PAN further allows a user or administrator to configure the operation of the onboard device using input/output components of the wireless device.Type: ApplicationFiled: June 29, 2010Publication date: October 21, 2010Applicant: GORDON * HOWARD ASSOCIATES, INC.Inventors: Stanley G.
