Patent number: 11973335Abstract: A solid state circuit breaker has both solid state electronics and a physical switch. The solid state circuit breaker facilitates power measuring for end loads connected to a panel board circuit, e.g. receptacles, lighting, etc., over current protection, and disconnection all within one device. The solid state circuit breaker can be used at 100% of its rated capacity as opposed to 80% code-mandated limitation for thermal magnetic circuit breakers. The solid state circuit breaker also can provide power/current data (real-time) without the need of an additional device. The solid state circuit breaker further facilitates electronic, i.e. remote, opening, closing, and current limiting for demand response or load shedding.Type: GrantFiled: June 11, 2020Date of Patent: April 30, 2024Assignee: RENU, INC.Inventors: Jumie Yuventi, Bahman Sharifipour, Liyang Zhang, Bruno Bambaren

Publication number: 20220396167Abstract: An electric vehicle solar charging system is disclosed, comprising a photovoltaic system or a DC source to transmit DC electricity to an electric vehicle via DC/DC conversion system. The DC/DC conversion is configured to directly transmit power to a battery pack configured to power the electric vehicle through the electric vehicle's DC charging inputs. This electricity can be supplemented by building battery or energy storage systems with DC output, or by DC electricity converted from AC which was supplied by AC sources. The combined circuit can be further modified by an in-line DC/DC converter at output if necessary, which also may be a bidirectional converter to supply energy from the EV back to the house load through a connected AC/DC inverter. When no DC is available, an AC power source can optionally provide supplemental power to the electric vehicle directly through the AC charging inputs.Type: ApplicationFiled: March 23, 2022Publication date: December 15, 2022Inventors: Bahman Sharifipour, Brian Reeves, Paul Reeves, Sean Burke

Patent number: 11032895Abstract: A wireless light switch harvests energy for ambient environment/space conditions and uses the harvested energy to energize low-power electronics. An exemplary application is for wireless control (ON/OFF or dimming) of light fixtures. The energy harvesting circuitry transduces ambient light to electricity and uses this energy to charge an energy storage device as well as power a wireless transmitter which can be triggered based on user interaction with an ON/OFF or Dim+/Dim? element. The wireless light switch with energy harvesting circuitry is paired with a wireless receiver circuit which can be connected to a light fixture that is to be controlled by the wireless light switch.Type: GrantFiled: December 3, 2019Date of Patent: June 8, 2021Assignee: Katerra Inc.Inventors: Bahman Sharifipour, Jumie Yuventi, Gary Fong

Patent number: 11026343Abstract: A thermodynamic heat exchanger is an electronic device having one or more heat generating devices, a heat exchanging element, and one or more heat exhaust elements. The heat generating devices can be the active and passive electronics elements included within a power conversion circuit, such as a power adapter used to charge a cellular telephone or other type of consumer electronics device. The heat exchanging element is configured to accept radiated thermal energy from the heat generating devices and distribute the accepted thermal energy across an outer surface to evenly distribute hot spots corresponding to the individual heat generating devices. The heat exchanging element is also configured to minimize heat radiating from its outer surface, thereby blocking heat in the thickness of the thermally conductive material.Type: GrantFiled: June 20, 2014Date of Patent: June 1, 2021Assignee: Flextronics AP, LLCInventors: Mark Telefus, Hongwei Du, Rowell Gapuz, Kevin Cui, Bahman Sharifipour, Laura Wen
