Abstract: Systems and methods of the present disclosure relate to using continuous contact radially phased centralizers in downhole operations. A centralizer comprises adjacent sections. Each adjacent section includes slots defined by adjacent non-slotted portions. Each slot is configured to pass fluid. The centralizer also includes a fluid channel that is disposed between each pair of adjacent sections to receive the fluid. The slots and the non-slotted portions are included in a radially phased arrangement that includes two or more of the adjacent section.

Abstract: The present invention relates to an alarm system that incorporates wireless technology along with cellular telephone service technology for example, to provide a unique and effective deterrent to illegal entry. The present invention further relates to an alarm system that first captures images of an intruder and then attacks the intruder with high intensity strobe lighting and audible signal broadcast in multiple pure square tones at high volume, creating an intolerable environment and triggering a “flight response” in the intruder.

Abstract: The present invention provides an apparatus for passively stabilizing the tuning element in tunable lasers. Lasers stabilized using the passive stabilization of the tuning element exhibit reduced mode hop and increased wavelength stability during temperature variations of the laser or surrounding environment. The stabilization makes the laser suitable for a broad range of applications including optical signal generators and optical multimeters.

Abstract: Disclosed are both a housing and an assembly for a tunable external cavity laser. The housing includes: a base section, a motion section, and an actuator. The base section includes a proximal and distal portion, and the laser and the dispersive element mounted at respectively the proximal and distal portions such that energy emanating from the laser strikes the dispersive element leaving the dispersive element as a second beam at an angle with respect to the first beam which depends on wavelength. The motion section includes a proximal and a distal portion and a torsional member positioned at the proximal portion and the reflector positioned at the distal portion to reflect the second beam to the laser via the dispersive element, and the motion section supported by the base about the torsional member.

Abstract: A protective post-guard apparatus and method for use in protecting rescue workers involved in vehicular rescue operations is disclosed. The post-guard is utilized to cover the jagged edges of exposed posts of a vehicle that has had the roof removed, or the steering wheel removed, thus affording access to victims in the vehicle.

Abstract: A water supply control apparatus includes a flow sensor, connected to a supply line of an indoor plumbing network, which sends a flow signal to a controller when flow is detected. The controller includes a power circuit which is interrupted upon detection of flow, thereby causing a shut-off valve to close. Moisture sensors and temperature sensors can also be coupled to the controller so that the shut-off valve can be closed in response to the detection of moisture or an incipient freeze condition.

Abstract: A water supply control apparatus for a household plumbing system having a main water supply line includes a shut-off valve disposed in the main water supply line, electric motor means for actuating the shut-off valve and being operable to move between open and closed positions, at least one temperature sensor adapted to be located in a position of exposure to cold temperatures, at least one moisture sensor adapted to be located in a position of exposure to water leaking from household appliances, control means, connected to the electric motor means, the at least one temperature sensor and the at least one moisture sensor, for actuating the shut-off valve to the closed position when either a freeze condition is detected by the at least one temperature sensor or a water leak is detected by the at least one moisture sensor.

Abstract: An automatic water supply shut-off system includes a shut-off valve movable between opened and closed positions in a line leading from the water supply. An electric motor actuates the shut-off valve and is electrically connected to a power source through an electric circuit so that when the circuit is closed the electric motor actuates the shut-off valve into the open position to allow water flow through the line. At least one temperature sensor feeds a signal to a logic circuit that controls a switch. The switch cuts off the supply of power to the electric motor when the sensor senses a temperature corresponding to a freeze condition.

Abstract: An automatic water supply shut-off system includes a shut-off valve movable between opened and closed positions in a line leading from the water supply. An electric motor actuates the shut-off valve and is electrically connected to a power source through an electric circuit so that when the circuit is closed the electric motor actuates the shut-off valve into the open position to allow water flow through the line. At least one temperature sensitive switch is disposed in the electrical circuit and is operative to normally close the electrical circuit above a predetermined temperature and to open the electrical circuit at or below the predetermined temperature, whereby the shut-off valve moves to the closed position.
