  • Patent number: 10267061
    Abstract: A locking system and method for a movable freight container comprises an electronic module with a shaft that goes into a cavity in a mechanical lock module. The shaft is securely retained in the cavity by a lock mechanism in the mechanical lock module by moving the lock mechanism to a locked position. A plurality of magnetic field sensors in the shaft are used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the lock mechanism to confirm continuous time insertion of the shaft in the cavity. A wireless communication component in the electronic module wirelessly transmits an alarm signal if the magnetic field sensors detect an unexpected interruption in at least one of the continuous time shaft position magnetic sensor readings.

    Abstract: A method and apparatus for detecting and preventing electrically induced fires in a gas tubing systems constructed of Corrugated Stainless Steel Tubing (CSST) and Gas Appliance Connectors (GAC). The system of the present invention may include one or more energy detection schemes to detect electrical energy surges on the gas line. When such a surge is detected, the control circuitry of the present invention causes an electric main gas valve de-energize into a closed position. In addition, the system of the present invention further includes a residual gas dispersal system that automatically vents the residual downstream gas pressure remaining in the gas tubing system after the closure of the main gas valve.

    Abstract: A microfluidic valve includes: a first structural layer and a second structural layer; a microfluidic circuit having a first microfluidic conduit and a second microfluidic conduit, which are defined in a superficial portion of the first structural layer, are adjacent, and are separated by a wall; a membrane set between the first structural layer and the second structural layer and delimiting the microfluidic circuit on one side; and a recess containing a gaseous fluid in the second structural layer. The membrane is movable in response to an actuation stimulus between a closed position, in which the first and second microfluidic conduits are fluidly decoupled, and an open position, in which the membrane is at least in part retracted into the recess and the first and second microfluidic conduits are fluidly coupled by means of a fluidic passage defined between the wall and the membrane.

  • Patent number: 8851443
    Abstract: Actuator apparatus having a multi-stable element actuated by memory alloy actuating elements. In one embodiment, the multi-stable actuator comprises a bistable (two-state) diaphragm element adapted to alternate between two stable configurations via forces exerted on the diaphragm by more than one memory alloy filaments in response to thermal activation. The bistable diaphragm element is coupled to a magnetic actuator element resident on a dry portion of a valve fitting, while a plunger actuated by the magnetic actuator element is resident on a wet portion of a valve fitting. Methods for making and using the bistable actuator apparatus are also disclosed.

  • Publication number: 20140276339
    Abstract: A tool includes a locator having a center aligned with a rotor axis when disposed over the valve. The locator has a first dimension approximately perpendicular with the rotor axis. A wall of the locator forms a volume to allow an adjustor to be disposed therein. The adjustor fits within the wall and has a magnet having a magnetic axis to unlock the rotor. An adjustable outer wall has a first position dimension permitting the adjustor to rotate about the center of the locator and aligning the magnetic axis with the center. The adjustable outer wall has a second position dimension less than the first dimension and the first position dimension. The adjustor can move lateral, rotational, and orbital in the locator misaligning the magnetic axis with the center. Misaligning the magnetic and rotor axes unlocks the rotors and the magnet maintains the unlocked state even when the axes are misaligned.

  • Patent number: 8820346
    Abstract: A self-actuating drainage device for placement on a structure to drain water accumulated on the structure includes a collection funnel having a bottom with a funnel hole extending therethrough, a siphon conduit contiguous with the funnel hole, the siphon conduit having a first end disposed on the structure and an opposite end disposed at a position lower than the first end. The device further includes a valve mechanism which includes a float maintained within the collection funnel. The valve mechanism opens when accumulated water raises the float so that the water collected in the collection funnel is released through the siphon conduit and starts a siphoning action from the first end to the opposite end when the valve mechanism closes.

  • Patent number: 8807523
    Abstract: A low-cost safety valve for gas lines and similar supply lines that can be remotely activated via a secure wireless link employing a low leakage sealing mechanism that is compatible with low energy actuators to for extended battery life. A miniaturized controller and wireless electronics assembly provides the control mechanism for actuating the valve, as well as reporting data regarding the valve status to wireless interrogators or external networks via an ad hoc wireless network. A variety of simple magnetic valve operating mechanisms can be implemented with the miniaturized electronic control circuits and the valve body. Such control actuation mechanisms enable automatic resetting or manual resetting valves. The gas line shut off valve can provide important safety benefits at an affordable price.
