Publication number: 20240104425Abstract: An approach is disclosed that receives, at a computer system, a set of biometric data readings pertaining to a user of the system. The biometric data readings are received from biometric sensors that are near the user. After receiving the biometric readings, an audible notification is transmitted to the user. Subsequently, a second set of biometric data readings pertaining to the user from the biometric sensors that are proximate to the user. The first and second sets of biometric data readings are compared with the comparison resulting in a confidence level that the user heard the transmitted audible notification. The audible notification is retransmitted in response to the confidence level being below a threshold not retransmitted in response to the confidence level meeting the threshold indicating that the user heard the first transmission.Type: ApplicationFiled: September 26, 2022Publication date: March 28, 2024Inventors: Russell Speight VanBlon, Kevin W Beck, Thorsten Stremlau, David Schwarz

Patent number: 8567495Abstract: A sensor is configured to sense pressure in an isolated or subterranean environment. The sensor is configured to act as a capacitor with a capacitance that varies as a function of pressure. The sensor has a robust design with minimal moving parts, and in which any parts that do move do not communicate electrically through direct electrical conduction (e.g., through conductive leads). Instead, moving parts that participate in the performance of sensor as a capacitor receive and dispense electrical charge only through a dielectric fluid (e.g., a gas or liquid within the sensor). This may reduce hysterysis, lag, and/or friction with respect to pressure-dependent capacitor designs in which wiring is connected directly to moving parts.Type: GrantFiled: October 20, 2010Date of Patent: October 29, 2013Assignee: Chevron U.S.A. Inc.Inventor: David W. Beck

Patent number: 8390471Abstract: A system, method and device may be used to monitor conditions in a borehole. Energy is transmitted to a pulse generator located proximate a position to be interrogated with a sensor. The pulse generator stores the energy, then releases it in a pulse of electromagnetic energy, providing the energy to resonant circuits that incorporate the sensors. The resonant circuits modulate the electromagnetic energy and transmit the modulated energy so that it may be received and processed in order to obtain the desired measurements.Type: GrantFiled: September 7, 2007Date of Patent: March 5, 2013Assignee: Chevron U.S.A., Inc.Inventors: Don M Coates, M.

Patent number: 8261607Abstract: Exemplary systems and method are directed to a sensing device, and to a pressure sensing system and method. An exemplary method includes supplying electromagnetic energy to a transducer which is configured to reflect the electromagnetic energy at a ring frequency determined by an inductance of the transducer, wherein the inductance changes in response to compression of the inductive element. The ring frequency of electromagnetic energy reflected by the transducer is correlated to a pressure value.Type: GrantFiled: October 4, 2010Date of Patent: September 11, 2012Assignee: Chevron U.S.A.

Publication number: 20120211278Abstract: A system, method and device may be used to monitor conditions in a borehole. Well tubing and casing act as a conductive pair for delivering power to one or more downhole active sensors. At the surface, power and signal are isolated so that the same conductive pair may act to transmit the sensor signals to the surface. In an embodiment, the sensor signals are RF signals and the surface electronics demodulate the RF signals from the sensor power.Type: ApplicationFiled: November 14, 2011Publication date: August 23, 2012Applicant: Chevron U.S.A., Inc.Inventors: Manuel E. Gonzalez, M. Clark Thompson, Robert L. Williford, David W. Beck

Patent number: 8106791Abstract: Exemplary systems and methods are directed to transmission of electromagnetic (EM) pulses in a downhole environment, which is located below a surface of a landform. A sequence of EM energy pulses is generated from a signal generator located at the surface of the landform. The energy pulses are reflected at a ring frequency by one or more downhole transducers. The reflected energy pulse is received at a receiver, which is located at the surface, during a predetermined time interval. The receiver detects the received energy pulses through a time domain or frequency domain technique. The detected ring frequency is correlated to a parameter or condition of the downhole environment.Type: GrantFiled: April 13, 2007Date of Patent: January 31, 2012Assignee: Chevron U.S.A.

Patent number: 4663814Abstract: A method and apparatus for removing a propeller hub secured by a nut to a tapered drive shaft. A puller abutment is fixed to the hub in position to engage the nut and prevent axial movement of the nut relative to the hub. Rotation of the nut against the axially immovable abutment results in axial movement of the hub, nut and abutment relative to the shaft, separating the hub from the shaft. Continued rotation of the nut separates the hub and nut from the shaft.Type: GrantFiled: November 12, 1985Date of Patent: May 12, 1987Inventor: David W. Beck
