Publication number: 20230326699Abstract: The invention relates to a circuit breaker for a low-voltage circuit having input and output terminals for conductors of the low-voltage circuit. Within the circuit breaker, the low-voltage circuit can be interrupted or closed. The circuit breaker also has a current sensor which determines the level of the electrical current in the low-voltage circuit and is connected to an electronic trigger unit which has a display for displaying information and interrupts the low-voltage circuit if current limit values or current-time limit values are exceeded. The display is designed to be removable.Type: ApplicationFiled: July 27, 2021Publication date: October 12, 2023Inventors: Michael Gerstner, Bernd Schwinn, Anand Venkatramani

Patent number: 11561534Abstract: A system and a method for industrial communication, employing an adaptive repeater supporting communication between at least two communicating devices using one of two or more predetermined communication protocols at a time instant, are provided. The adaptive repeater includes a communication direction module and a protocol adapter module operably coupled to one another. The communication direction module detects a direction of communication between the communicating devices using physical layer parameters of the communication protocols, and establishes communication there-between, using a sampling clock. The protocol adapter module adapts the communication direction module to the communication protocol in use, by generating the sampling clock.Type: GrantFiled: August 6, 2018Date of Patent: January 24, 2023Assignee: Siemens AktiengesellschaftInventors: Chetan Sharad Deokar, Slava Friesen, Michael Geppert, Robert Heislbetz, Anusha Kurra, Anand Venkatramani

Patent number: 10992176Abstract: A power harvesting system is provided for harvesting power from a current carrying conductor for powering a load. The power harvesting system includes an energy conversion module at least partially disposable on the current carrying conductor, and an impedance regulation module coupled to the energy conversion module. The energy conversion module couples an induced voltage proportional to a line current flowing in the current carrying conductor, for powering the load. The impedance regulation module dynamically regulates impedance in the power harvesting system for controlling transfer of the power harvested using the induced voltage and the line current, to the load.Type: GrantFiled: April 12, 2019Date of Patent: April 27, 2021Assignee: Siemens AktiengesellschaftInventors: Siraj Issani, Anand Venkatramani
