Abstract: A three-dimensional video signal is generated by an objective lens, a stereo lens optical system, such as a stereo doublet lens for example, one or more image-to-signal converters, and a multiplexer. A three-dimensional monitor or two head mounted monitors may be used to render (e.g., display) the three dimensional video signal.

Abstract: A latch assembly of the present invention comprises a link member and a latch body. The latch assembly is adapted for use with a storage container having a container body and a container lid connected to the container body. The container lid is connected to the container body in a manner to permit movement of the lid between open and closed positions relative to the container body. The link member is moveably connected to the container body. The latch body includes at least one lug and at least one retaining arm. The lug is integral with the latch body and has a lug recess adapted for receiving a first portion of the link member in a manner to permit pivoting movement of the link member relative to the lug. The retainer arm is integral with the latch body and is adapted for engaging the link member in a manner to prevent the link member from being released from the lug recess. The latch assembly is adapted for movement relative to the container body between a locked position and an unlocked position.

Abstract: A lightweight, collapsible boat comprises twin parallel hulls, a frame and human-powered paddlewheels outboard of the two hulls. The boat's frame is capable of being collapsed and packed into a bundle for carrying as a backpack. The drive comprises a pedal drive for turning a short drive axle which is independently and releasably coupled to paddlewheel driveshafts. Steering of the boat is accomplished by selective engaging and disengaging of the left and right couplings The frame comprises a steering column, an operator's seat support, rear hull spacing members and front hull spacing members which support the driveshafts.

Abstract: An "isoharmonic" sports bat, for example a baseball bat or cricket bat, includes a hitting surface for impact with a ball, wherein the duration of a half cycle of a selected mode of vibration of the hitting surface when in contact with the ball is approximately equal to the contact time between the hitting surface and the ball during an average impact. This allows the vibrational energy of the bat to be returned efficiently to the ball, which improves the coefficient of restitution, and the peak contact force between the bat and the ball may be reduced. The hitting surface may be formed by a plate attached to the bat.

Abstract: A pressurized fluid dispensing nozzle (110') such as for LPG is screw-threadedly engageable with a tank inlet (192) such as on a vehicle. A sealing sleeve (154) carrying a nose piece (140') is biassed into abutment with a gasket (194) on a seal face (196) of the tank inlet and is urged rearwardly by the abutment. The sealing sleeve (154) is slidably mounted on a sealing member (136') which is urged rearwardly with the sealing sleeve (154) into a valve actuating condition. A trigger (118') is actuated to open a valve assembly (120') by shifting the valve assembly forwardly to bring a valve body (126') into abutment with an actuator (132') on the sealing member (136) which lifts the valve body off a valve seat (128'). The pressurized fluid passes along a passage (146') through the sealing member (136') to be dispensed but part of it enters a chamber (150) through ports (134').
