Patent number: 11987677Abstract: A mechanically and piezoelectrically anisotropic polymer thin film is formed from a crystallizable polymer and an additive configured to interact with the polymer to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film and its method of manufacture may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example polymers may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. Example additives may occupy up to approximately 60 wt. % of the polymer thin film. The polymer thin film may be characterized by a piezoelectric coefficient (d31) of at least approximately 5 pC/N or an electromechanical coupling factor (k31) of at least approximately 0.1.Type: GrantFiled: December 22, 2021Date of Patent: May 21, 2024Assignee: Meta Platforms Technologies, LLCInventors: Sheng Ye, Hao Mei, Cody Wayne Weyhrich, Arman Boromand, Andrew John Ouderkirk, Christopher Yuan Ting Liao, Emma Rae Mullen, Christopher Stipe, Nagi Hosni Elabbasi, Rui Jian

Publication number: 20240072408Abstract: A planar antenna providing a heating function includes a radiating element and a ground element disposed over a surface of a substrate, wherein the radiating element and the ground element are conductive. The ground element includes a conduction path between a first connection point and a second connection point. The ground element is adapted to be connected to a power source to provide a voltage between the first connection point and the second connection point, thereby producing heat by providing a current through the ground element along the conduction path.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Christopher B.

Publication number: 20240072409Abstract: A planar antenna that provides a heating function is fabricated by printing a pattern of catalytic ink onto a surface of a web of flexible substrate. The printed pattern of catalytic ink defines an antenna pattern including a radiating element and a ground element. A conductive material is electrolessly plated onto the pattern of catalytic ink by transporting the web of flexible substrate through a reservoir of plating solution to form a corresponding pattern of conductive material. The electrolessly-plated ground element includes a conduction path between a first connection point and a second connection point, wherein the electrolessly-plated ground element is adapted to be connected to a power source to provide a voltage between the first connection point and the second connection point, thereby producing heat by providing a current through the ground element along the conduction path.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Christopher B.

Publication number: 20080117081Abstract: A traffic analyzer for detecting a magnetic permeable mass passing a fixed position includes a calibrated magnetic background memory device, a first magnetic field detector, a second magnetic field detector, a window comparator, and a programmable processor. The first magnetic field detector is operative to detect a change in a magnetic field caused by a magnetic permeable mass passing the magnetic field detector. The window comparator then generates a comparative output of the detected change and a threshold value stored in the calibrated magnetic background memory device. The window comparator then generates a comparative output to place the programmable processor in an active state. The programmable processor is then operative to calculate characteristic data of the magnetic permeable mass using the output from the first and second magnetic field detectors. The characteristic data may be stored in a memory storage device according to a dynamic distribution classification.Type: ApplicationFiled: March 12, 2007Publication date: May 22, 2008Inventors: Peter Jerome Radusewicz, Thomas Christopher Rae, Angelo Libertino

Patent number: 6388849Abstract: An arc fault detector includes an average instantaneous current generator which averages the current over the fundamental period and produces a substantial output only where there are substantial variations in waveform between half-cycles which is indicative of an arc. To discriminate over inrush currents, a pulse generator generates a pulse in response to the step increase in current caused by striking of an arc. An output circuit generates an arc signal when the time attenuated accumulation of pulses occurring in half-cycles in which the average instantaneous current is above a selected threshold reaches a predetemiined level. To further discriminate over dimmers during turn on of a cold tungsten bulb, die ANDing with the average instantaneous current is delayed until a time attenuated accumulation of the pulses reaches a threshold value. The average instantaneous current can be approximated by a bandpass filter with a center frequency below the fundamental of the ac current.Type: GrantFiled: February 14, 2000Date of Patent: May 14, 2002Assignee: Eaton CorporationInventor: Thomas Christopher Rae

Patent number: 5896262Abstract: An arc fault detector of the type which generates a trip signal when a time attenuated accumulation of pulses produced each time an arc is struck reaches a selected value, includes a pulse conditioner which discriminates against false trips induced by phenomena such as tungsten bulb burn out and turn on of a cold tungsten bulb controlled by a dimmer. The pulse conditioner includes a zener diode which limits the amplitude of the pulses applied to the integrator, and stretches all of the pulses to reduce the variation in pulse duration. The latter can be accomplished by a peak detector which stretches pulses which reach the zener limit to a duration of at least about a half cycle.Type: GrantFiled: February 26, 1998Date of Patent: April 20, 1999Assignee: Eaton CorporationInventors: Thomas Christopher Rae, Thomas Edward Natili, Robert Tracy Elms

Patent number: 5805398Abstract: A circuit breaker with an arc fault circuit provides immunity to false trips caused by tungsten bulb burnout and by a cold tungsten filament energized through a solid state dimmer. The detector circuit includes a pulse generator which generates pulses in response to the step increases in current occurring each time an arc is struck. A zener diode limits the amplitude of pulses generated by the pulse generator to a value which is below that of pulses generated by the tungsten lamp. When a time attenuated accumulation of these pulses reaches a predetermined value, the circuit breaker is tripped. By clipping the pulses with the zener diode, the few large pulses generated by tungsten bulb burnout or energization of a cold tungsten bulb by a solid state dimmer switch are insufficient to allow the time attenuated accumulation of pulses to reach the trip value.Type: GrantFiled: September 29, 1997Date of Patent: September 8, 1998Assignee: Eaton CorporationInventor: Thomas Christopher Rae
