20090174981 | NONVOLATILE STATUS INDICATOR SWITCH - A non-volatile status indicator switch is provided. In one embodiment, the invention relates to an aircraft electrical system including a fault detection circuit coupled to a relay, and a fault indicator circuit coupled to the fault detection circuit and to a control input of the relay, wherein the fault indicator circuit includes a nonvolatile memory element, wherein the fault detection circuit is configured to detect a fault and to provide a signal indicative of the fault to the fault indicator circuit, and wherein the fault indicator circuit is configured to respond to the signal indicative of the fault by providing a predetermined control signal to the relay and by storing information indicative of the detection of the fault in the nonvolatile memory element. | 07-09-2009 |
20100073840 | Emergency utility interruption system - A device is provided for the prevention of damage due to the continued supply of a utility to an appliance, the device comprising: 1) a detector which detects circumstances of present or impending emergency and responds by sending a detector signal to 2) a receiver which receives a signal from the detector and in response emits a receiver signal; 3) a transmitter which receives the receiver signal and in response signals a 4) restrictor to attenuate or quench a utility supply to an appliance. | 03-25-2010 |
20100073841 | APPARATUS AND METHOD FOR FIRE PROTECTION OF ELECTRICAL INSTALLATIONS - A system for detecting and preventing an electrical fire in a domestic electricity distribution system comprising an intake fuse box, a main distribution panel comprised in a main panel housing, a subdistribution panel comprised in a subpanel housing, a main power circuit connecting the intake fuse box to the main distribution panel, and a sub power circuit connecting the main distribution panel to the subdistribution panel. First, second and third gas, smoke and heat detectors are arranged in respective ones of said intake fuse box, said main panel housing, and said subpanel housing, and being adapted to provide respective first, second and third low level outputs if subjected to a gas, smoke or heat exceeding a first threshold and to provide respective first, second and third high level outputs if subjected to a gas, smoke or heat exceeding a second threshold. A remote controlled main level circuit breaker is arranged in the main power circuit, a remote controlled sub level circuit breaker is arranged in the sub power circuit, and a controller unit has first, second and third inputs connected to respective ones of said first, second and third gas, smoke and heat detectors for receiving respective ones of said first, second and third low and high level outputs, an alarm output, and first and second breaker control outputs connected to respective ones of said main level and sub level circuit breakers. | 03-25-2010 |
20120106017 | Short-Circuit Protection for an Electric Vehicle Battery - Device for electrically protecting an electric vehicle. To protect high voltage batteries of electric vehicles in the event of floods, a disconnecting device | 05-03-2012 |
20120320484 | Fire Sentry - The Fire Sentry is a unique Fire Prevention Device. This Device will disengage the Electrical Power to the Cooking Appliance in which it is connected to. This Device will detect Black Smoke from a Stove or other Cooking appliance before it has the chance to combust and create a Fire. Once the Black Smoke has been removed from the Fire Sentry's Sensors the unit can be reset and normal cooking/heating can be resumed. | 12-20-2012 |
20120320485 | LEAKAGE DETECTION PROTECTION CIRCUIT WITH LIGHTNING PROTECTION - An electrical protection circuit comprises a circuit board, an induction coil, a self-exciting coil, a control chip, a silicon controlled rectifier, a rectifier diode, a resistor, a filtration capacitor, a trip coil with iron core, a group of main circuit switches, and a reset button. An analog electric single-pole double-throw switch linked with the reset button comprises a traveling contact lever, a first static contact jaw, and a second static contact jaw. When the reset button is in a tripped or reset state, the traveling contact lever is connected with the second static contact jaw and the switch is in a closed state. When the reset button is pressed down, the traveling contact lever disconnects from the second static contact jaw, contacts the first static contact jaw, then disconnects from the first static contact jaw and returns to the closed state with the second static contact jaw. | 12-20-2012 |
