Patent number: 8482162Abstract: A system adapted to replace a mechanical switch with an electronic switch, without the need of additional wiring. The electronic switch includes a bridge array for sensing a characteristic, e.g., temperature or pressure, and an electronic circuit having a switch. As the characteristic of the bridge array varies a switch changes states.Type: GrantFiled: May 3, 2010Date of Patent: July 9, 2013Assignee: Kulite Semiconductor Products, Inc.Inventor: Wolf S. Landmann

Publication number: 20130140911Abstract: A method and device are disclosed for diodeless terrestrial photovoltaic solar power arrays. In one or more embodiments, the method and device involve a solar power array device without blocking diodes and/or without bypass diodes. The method comprises providing a solar module, a solar array tracker, a power bus, a controller, and an inverter. In one or more embodiments, the method further comprises providing a circuit breaker and/or a bi-position switch. When the controller senses that the solar module power is below a threshold level, the controller commands the solar tracker to vary the solar module's pointing until the solar module is operating at its maximum power point for the solar module's level of illumination. In some embodiments, when the controller senses that the solar module power is less than a minimum bypass threshold level, the controller commands a bi-position switch to bypass current around the solar module.Type: ApplicationFiled: August 17, 2012Publication date: June 6, 2013Applicant: THE BOEING COMPANYInventors: Charles H. Hightower, Jeff E. Frericks, Authi Ariamuthu Narayanan

Patent number: 8450879Abstract: A power control apparatus comprises a transducer having an output (12,13) which is connected to a remotely activated device (25) mounted in a mains consumer unit (14). When a predefined parameter is detected, the device (25) is activated to connect a load (29) between the switched live output (18) of a residual current device RCD (15) and the neutral input (17) thereof, thereby creating an imbalanced current flow on the live and neutral output terminals (18,19) of the RCD (15) which causes contacts (20,21) inside the RCD (15) to disconnect the supply to an appliance circuit (22).Type: GrantFiled: September 28, 2008Date of Patent: May 28, 2013Inventor: Graham Chilvers

Publication number: 20130113302Abstract: This invention is to control and monitor a solar module by optical communication using solar cells in the solar module as a receiver of the incoming optical signal. The optical communication is by way of solar cells in a solar module as sensors and/or receivers, and busbars of the solar module as conduits to transfer the incoming signal to a control circuitry. Such control includes, but is not limited to, on/off control of power output from a solar module, and such monitoring includes, but is not limited to, reading, data keeping and displaying current operating performance status of the solar module. With this invention, solar modules can be turned off and on without physically disconnecting and reconnecting wires. Such control and monitoring enables more efficient and accurate operation and maintenance of a solar power system of any size.Type: ApplicationFiled: September 10, 2012Publication date: May 9, 2013Inventors: Mansoon Jeong, Byeong Keon Son

Patent number: 8410445Abstract: The present invention relates to a human body sensing apparatus with improved accuracy, in which whether a moving direction of a human body is a ‘determinate entry or exit’ or an ‘indeterminate entry or exit’ is determined by analyzing a sensing signal outputted from each of sensor units, and room occupancy states are classified into a ‘ZERO’ state, a ‘CHECK’ state, a ‘WAIT’ state, an ‘AOL’ state and an ‘IOL’ state depending on a determined result. Even a variety of unexpected behaviors that a human can perform in a sensing area of the sensor units can be detected, and thus correctness and correction rate are superior in calculating the number of people staying in a room.Type: GrantFiled: May 24, 2012Date of Patent: April 2, 2013Assignee: LINUDIX Co., Ltd.Inventors: Ji-yong Kim, Yu-Chul Kim, Yong-Duck Lee
