Publication number: 20240003755Abstract: Aspects of the present disclosure include using particles in phase change materials to track temperature change of an object. The particles may be initially disposed at specific locations within the phase change materials. As the phase change materials transition from the solid state to the fluid state, the particles may move from the initial locations to different locations. The change in locations of the particles may be detected magnetically, electrically, optically, and/or visually. Such change may indicate that the object experienced a temperate above at least one phase transition temperature of the phase change materials.Type: ApplicationFiled: June 28, 2023Publication date: January 4, 2024Inventors: Alan O'DONNELL, Shaun Stephen BRADLEY, Michael P. LYNCH, Padraig L. FITZGERALD, Jochen SCHMITT, Jan KUBIK, Javier CALPE, Michael J. CLIFFORD, Stanislav JOLONDCOVSCHI, Gavin P. COSGRAVE, Alfonso BERDUQUE

Publication number: 20220326322Abstract: The present disclosure provides a magnetic field sensor system, comprising an AMR magnetic field sensor and an overcurrent detection sensor. The overcurrent detection sensor comprises an AMR sensing element connected in a half bride arrangement with a field insensitive component. The output of the overcurrent detection sensor is able to monitor the strength of the magnetic field experiences by the sensor system, and detect if the magnet field goes beyond a sensing threshold of the AMR magnetic field sensor. Outside of this threshold, the AMR magnet field sensor is unable to provide a measurement of the magnetic field strength. The overcurrent detection sensor can therefore detect that the system is operating in very high magnetic fields, which in turn can indicate that there is overcurrent in the system.Type: ApplicationFiled: April 13, 2022Publication date: October 13, 2022Inventors: Jochen Schmitt, Gavin P.

Publication number: 20210336402Abstract: The present disclosure relates to a laser system/package that is configured to enable the detection of a change in an optical device that is intended to alter light emitted from the laser. The system is designed to measure an electric or magnetic field that is affected by the optical device. As a result, changes in the optical device, for example because the optical device has been damaged or dislodged or removed, should be detected by a corresponding change in the electric or magnetic field.Type: ApplicationFiled: March 2, 2021Publication date: October 28, 2021Inventors: Jonathan Ephraim David Hurwitz, Eoin E.

Patent number: 9385673Abstract: Aspects of this disclosure relate to compensating for a relatively large offset in a signal generated by a sensor, such as a pressure sensor and/or a resistive bridge based sensor. Such offset compensation can include applying an offset correction signal generated by a configurable voltage reference, such as a voltage mode digital-to-analog converter (DAC), to an input of an amplifier included in an instrumentation amplifier to compensate for the offset of the signal generated by the sensor.Type: GrantFiled: July 1, 2014Date of Patent: July 5, 2016Assignee: Analog Devices GlobalInventors: Fazil Ahmad, Gavin P.

Patent number: 9088256Abstract: An amplifier includes a fault protection control circuit biased from the signal pin and a fault protection circuit including a first PMOS transistor and a second PMOS transistor. The sources and bodies of the first and second PMOS transistors can be connected to one another, the drain of the first PMOS transistor can be connected to the amplifier's output, and the drain of the second PMOS transistor can be connected to a signal pin. During normal operating conditions, the fault protection control circuit can turn on the first and second PMOS transistors. However, the fault protection control circuit can turn off the first PMOS transistor and turn on the second PMOS transistor when an overvoltage condition is detected, and can turn on the first PMOS transistor and turn off the second PMOS transistor when an undervoltage condition is detected, even when the integrated circuit is unpowered.Type: GrantFiled: August 8, 2012Date of Patent: July 21, 2015Assignee: Analog Devices, Inc.Inventors: Gavin P.

Patent number: 8947841Abstract: Harsh electrical environments integrated circuit protection for system-level robustness and methods of forming the same are provided. In one embodiment, a protection system includes dual-polarity high blocking voltage primary and secondary protection devices each electrically connected to a pad. The primary protection device has a current handling capability greater than a current handling capability of the secondary protection devices, and the secondary protection device has a turn-on speed that is faster than a turn-on speed of the primary protection device so as to decrease pad voltage overshoot when a fast transient electrical event occurs on the pad. Additionally, the holding voltage of the primary protection device is less than a holding voltage of the secondary protection device such that once the primary protection device has been activated the primary protection device clamps the pad voltage so as to minimize a flow of high current through the secondary protection device.Type: GrantFiled: February 13, 2012Date of Patent: February 3, 2015Assignee: Analog Devices, Inc.Inventors: Javier A Salcedo, David J.
