Patent number: 11798750Abstract: An arc suppressing circuit configured to suppress arcing across a power contactor coupled to an alternating current (AC) power source having a predetermined number of phases, each contact of the power contactor corresponding to one of the predetermined number of phases includes a number of dual unidirectional arc suppressors equal to the predetermined number of phases of the AC power source. Each dual unidirectional arc suppressor includes a first phase-specific arc suppressor configured to suppress arcing across the associated contacts in a positive domain, a a second phase-specific arc suppressor configured to suppress arcing across the associated contacts in a negative domain, and a coil lock controller, configured to be coupled between a contact coil driver of the power contactor, configured to detect an output condition from the contact coil driver and inhibit operation of the first and second phase-specific arc suppressors over a predetermined time.Type: GrantFiled: June 13, 2022Date of Patent: October 24, 2023Assignee: Arc Suppression TechnologiesInventors: Reinhold Henke, Warren Kahle

Publication number: 20230238792Abstract: An arc flash suppressor, system, and method are disclosed. The arc flash suppressor includes a main processor, a current sensor processor, a voltage sensor processor, a plasma ignition detector, and an arc flash extinguishing circuit. The current sensor processor is configured to detect a slew rate of an input current from a power source. The voltage sensor processor is configured to detect a slew rate of an input voltage from the power source. The main processor is configured to cause the arc flash extinguishing circuit to create a short circuit condition over the power source to extinguish an arc flash upon detection of a critical current slew rate, a critical voltage slew rate, and plasma ignition.Type: ApplicationFiled: July 27, 2022Publication date: July 27, 2023Inventors: Reinhold Henke, Warren Kahle

Patent number: 6195436Abstract: A multi-station audio distribution apparatus having at least two listening stations, a data control mechanism and a listening station interface mechanism disposed between the listening stations and the data control mechanism. Each of the listening stations has a user input in the form of a bar code scanner to enter an audio material selection and each has an audio output. The data control mechanism retrieves digitized audio material corresponding to each of the user's audio material selections. The listening station interface mechanism transfers the user's inputs from each of the listening stations to the data control mechanism, receives the digitized audio materials corresponding to each user's input from the data control mechanism, converts the digital audio materials to analog audio signals and transfers the analog audio signals to each of the respective listening stations for the audio output.Type: GrantFiled: January 15, 1998Date of Patent: February 27, 2001Assignee: Advanced Communication Design, Inc.Inventors: Marco Scibora, Warren Kahle
