Patent number: 11916619Abstract: A tuning circuit for a near-field magnetic induction (NFMI) system suitable for near field communication (NFC) is disclosed. The NFMI system includes a tuning circuit that is configured to measure a phase across a series capacitor coupled between a resonant circuit and a transmit circuit in order to determine a resonant condition of the resonant circuit. When the resonant condition is above resonance or below resonance, the tuning circuit can tune an adjustable capacitor of the resonant circuit. The tuning can continue until the phase measurement indicates that the resonant circuit is at resonance. The phase-based tuning allows for the tuning to operate continuously and concurrently with NFC.Type: GrantFiled: February 10, 2022Date of Patent: February 27, 2024Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Gareth Pryce Weale

Patent number: 11480468Abstract: A terahertz detector circuit can include a high electron mobility transistor (HEMT) having multiple gates that can be controlled by gate signals to generate a gate-induced modulation pattern in a two-dimensional electron gas (2DEG) of the HEMT. When the gate induced modulation pattern substantially matches a signal induced modulation pattern generated by an incident terahertz signal then a detection efficiency of the incident terahertz signal is improved. Accordingly, an electronically tunable THz detector with high efficiency can be realized. When these THz detectors are arranged in an array and electrically coupled, THz images and/or multi-spectral THz images may be generated.Type: GrantFiled: September 11, 2020Date of Patent: October 25, 2022Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Gareth Pryce Weale, Jan Chochol

Patent number: 11239707Abstract: A tunable resonant inductive coil system includes an electrical circuit having an alternating current (AC) voltage source, a barium strontium titanate (BST) variable capacitor coupled in series with a first terminal of the AC voltage source, a coil coupled in series with the BST variable capacitor, and a return line coupling the coil with a second terminal of the AC voltage source and/or a ground. The electrical circuit forms an LC circuit (resonant circuit). The electrical circuit adjusts between two configurations. In the first configuration the resonant circuit has a first resonant frequency configured for wireless power transfer and in the second configuration it has a second resonant frequency configured for near field communication (NFC). An entire length of the coil is used for both resonant frequencies. Adjusting between the first and second configurations includes varying a capacitance of the BST variable capacitor in response to receiving a control signal.Type: GrantFiled: November 15, 2018Date of Patent: February 1, 2022Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Gareth Pryce Weale

Patent number: 11165281Abstract: A wireless power transmission (WPT) system. Implementations may include a power source coupled with a first wireless power transmission (WPT) system and a load coupled with a second WPT system including a sense circuit.
