  • Patent number: 9688150
    Abstract: A system and method for controlling an environmentally-friendly vehicle perform a safety function by blocking a high voltage output of a high voltage battery at the time of a rear-lateral side collision of the environmentally-friendly vehicle. The high voltage blocking function is smoothly performed at the time of the rear-lateral side collision accident by determining a rear-lateral side collision of the environmentally-friendly vehicle using a blind spot detection sensor, a lane change alert sensor, or a rear cross traffic alert sensor, along with a yaw rate sensor that detects a yaw rate, and turning off a relay of the high voltage battery at a moment when the rear-lateral side collision is determined.

  • Patent number: 9269516
    Abstract: An original apparatus that will react and shut off a main fluid source during a severe earthquake. A steel ball is held at an elevated position by a secured magnet. In a severe earthquake, the seismic vibrations will cause the steel ball to break away from the magnet and fall onto the slide trigger. The weight of the steel ball and slide trigger will be pushed down and the slide trigger shall engage a momentary switch that will send voltage to a normally open motorized ball valve and cause it to close. The apparatus can be reset by manually pulling upward the lift handle towards the top cap. Resulting in the momentary switch to disengage and the voltage will seize to power the normally open motorized ball valve, causing it to go back to its normally open state. Thus allowing the fluid to pass through the ball valve.

    Abstract: A gas shut-off valve assembly designed to automatically close gas flow in a gas conduit in response to a seismic vibration comprises a trigger mechanism disposed in a trigger mechanism housing, a springless sealing mechanism disposed in a valve housing, a latching mechanism configured to engage the springless sealing mechanism to keep the gas conduit open, and a pressure release valve. Upon sensing a seismic vibration, the trigger mechanism disengages the springless sealing mechanism from the latching mechanism. Simultaneously, the springless sealing mechanism swings down and rotates around an axis by gravitational force to close off gas flow in the conduit. To reopen gas flow, the pressure release valve is actuated to relieve accumulated gas pressure inside the valve housing and the springless sealing mechanism is manually reset to its original open position.

    Abstract: A self-contained valve actuator of the present invention can comprise an actuator component. This actuator can be linear or quarter turn depending on the valve. The actuator can be double acting which means the piston will move once to open and once to close. The self-contained valve system uses hydraulic fluid to operate the valve. The valve system is directly powered with electric power from a battery. Solar panels are also incorporated to capture solar energy and convert this energy into electrical energy. This converted electrical energy is stored in the battery which enables the battery to continuously supply energy while substantially reducing the possibility of exhausting battery power. This resupply of electrical energy and the use of the hydraulic fluid creates a self-contained valve actuation system.

    Abstract: According to one embodiment, a power supply device includes a fuel cell, a pipe passage, a fuel pump, a component, a tilt sensor, a pressure regulator, a pressure calculator, and a pressure controller. The fuel cell generates electric power using liquid fuel. The pipe passage supplies the liquid fuel to the fuel cell. The fuel pump sends the liquid fuel to the pipe passage. The component is located in the pipe passage. The tilt sensor detects a tilt angle of the component. The pressure regulator regulates the pressure of the liquid fuel applied to the component. The pressure calculator calculates a variation in the pressure of the liquid fuel applied to the component based on the distance between the component and the pressure regulator and the tilt angle. The pressure controller controls the pressure regulator to maintain the pressure applied to the component within an allowable pressure range.

  • Patent number: 7918239
    Abstract: A horizontal and vertical shock responsive fluid valve assembly which are capable of automatically closing a fluid valve in response to earthquake forces or other shock forces of a predetermined magnitude. The assemblies are comprised of a respective horizontal and vertical shock and vibration force triggering mechanism working in a similar fashion. The mechanism has a respective cradle comprising a generally concave transverse surface that holds a movable ball and when it is energized by the forces can rotate 360 degrees in any direction and rolls out of the surface such that the ball ricochets off a housing cover covering the cradle and activates the mechanism only when the external forces reach a predetermined magnitude.

  • Publication number: 20100096022
    Abstract: It is disclosed a shut-off valve which acts automatically and has a fully mechanical performance with respect to the loosing of the tower-shape part balance under the effect of the special acceleration which is arisen from the quakes waves or serious vibrations, while such vibrations are mainly resulted from collision or effusion. A static tower has been applied for the main core of this part of the valve which loses balance state under the effect of collision and bounces to the neighboring part, which results in release of the catch and blockage of the gas passing channel.

    Abstract: A water scavenging system (1) for removing water from an aircraft fuel tank (2), the water scavenging system comprising: a water line (10); and a valve (20) which is configured to control the flow of water in the water line in response to a change in an effective angle of the valve. In use, the valve opens automatically in response to an increase in the effective pitch of the aircraft during take off and climb. The valve comprises: a pendulum (40); and a valve closure member (46) which is coupled to the pendulum such that a change in the angular position of the pendulum relative to the water line causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve.

  • Patent number: 7650901
    Abstract: A gas shutoff valve having a ball normally residing in a first seat, wherein sufficient disturbance of the valve causes the ball to escape the first seat and settle into a second seat wherein a flow of gas is blocked. The first seat is on an upper surface of a seating ball held in a base portion of the valve. The seating ball is held in place by a plate and is adjustable to compensate for gas line angles away from vertical. Adjustments to the seating ball may be made using a leveling tool inserted through a tool port in the base portion and inserting into a tool seat in the seating ball.

  • Patent number: 7546679
    Abstract: Apparatus and associated systems or methods include a linear machine with an elongate, axially-slidable core member (i.e., shaft). In one embodiment, the shaft includes at least one radial aperture to provide fluid (e.g., air) communication from an interior volume of a winding tube that contains one or more stationary windings, to either end of the shaft through a lumen that extends axially through the length of the shaft. The stationary windings are spaced apart to permit fluid to flow through a plurality of radial apertures in the winding tube. In particular, fluid circulation across the windings may provide sufficient cooling to increase the machine's maximum current rating. The fluid circulation may also provide pneumatic processing capabilities (e.g., vacuum hold, blow-off). In one exemplary embodiment, the apparatus may be used to insert tube-and-square paper separators into battery casings at high rates.
