A latch assembly includes a latch bolt, a retaining member and an actuator. The latch bolt is moveable between a closed position at which it is capable of retaining a striker and an open position at which the striker is released. The retaining member is moveable between a retained position at which it retains the latch bolt in at least its closed position and released position at which the latch bolt can move between its opened and closed positions. The actuator is capable of moving the retainin...

A boatlift assembly having a boat cradle portion and a canopy portion. The canopy portion and boat cradle portion are movably coupled to cause the canopy portion to be automatically raised when the boat cradle is lowered and to be automatically lowered when the boat cradle is raised.

A system and method have been provided for synchronizing the timing of line cards and switch cards in a broadband switch. Synchronization is accomplished using an auxiliary data link between the line and switch cards. One of the switch cards is selected as the master switch card. The master switch card receives timing information from the line cards, and in turn, sends timing correction signals to each of the line cards. Each line card acquires synchronization using its respective timing correct...

A vapor flow controller apparatus for delivery of chemical reagent vapors from a liquid phase source material is provided which includes a source container containing the liquid phase source material, a pump to transport the liquid phase source material to a vaporizor module, the pump having a flow rate controller, and the vaporizer module having a source material inlet, a carrier gas inlet, and a vaporized gas outlet. The vaporizer module converts the liquid phase source material to a vapor. Th...

A lock latch mechanism disposed within a powered locking device of a transit vehicle door system for maintaining a lock lever in an unlock position without the aid of the lock actuator. The lock latch mechanism includes a lock latch lever biased for engagement with an unlock cam through the use of a bias spring. The lock latch mechanism further includes a reset lever assembly engaging such lock latch lever during the door closing motion to allow movement of the lock lever form such unlocking pos...

The shaft engaging portion body includes a plurality of flexible fing...

Radio communication system and method capable of expanding the coverage of a radio base station and thereby permitting efficient radio communications. A continuous time slot allocating unit continuously allocates time slots in a frame to generate a continuous time slot. During the period of the continuous time slot, a propagation information calculating unit communicates with a terminal unit to calculate propagation information about radio wave propagation between the radio base station and the ...

A system and method for reducing the content of ammonia in water provides a submerged surface having a growth of nitrifying bacteria thereon. An aeration system creates air bubbles that travel along the surface as they rise to create aerobic conditions on the surface, and to circulate the water along the surface to allow the nitrifying bacteria to remove ammonia from the water.

An amplifying device for a sensor (10) delivering a response in voltage or impedance has a voltage controlling means for the sensor and at least an additional impedance (12). The voltage controlling means (22) is connected to output terminals (16, 20) of the sensor to maintain a noticeably constant voltage between the terminals. The additional impedance (12) is connected in series with the sensor within a polarization circuit, between the output terminals (18 16; 18 20) of the device. The amplif...
