摘要： An exercise apparatus having a frame with an adjustable weight bearing ratchet and pulley system with laser timer and display is disclosed. A force controlled laser timing device mounted to the frame which measures via time movement within a given space. An OLYMPIC barbell is located within the center of the device being attached to the ratchet and pulley system for the purpose of controlling gravitational resistance. A user-controlled strap is wound about the barbell so that the force implemented by the user will not allow the adjustable weights or barbell to become lose and dangerous. Movement of the barbell by the user is measured and recorded for weight and time.

摘要： An apparatus for collapsing and collecting a can utilizing a tray having a first portion with a surface and a second portion with an opening through the same. A housing is also provided and includes a press which is movable between a first position and a second position. The tray is guided relative to the housing such that the surface of the first portion lies opposite the press and is capable of collapsing a can when placed on the first tray portion. When the press moves to its first position the can is collapsed. The collapsed can passes through the tray when the tray second portion lies opposite the press.

摘要： An invention disclosed herein pertains to a thruster suitable for underwater vehicles. Such a thruster includes a steerable duct and propeller. The thruster motor, the two directional servo motors and all necessary electronics are contained in a single fluid filled and pressure compensated container. This is made possible, by a compact steering mechanism that allows the propeller and duct to be steered about the pitch and yaw axis of the vehicle and a spherical rolling seal which allows the fluid in the thruster to be maintained at a pressure of 2-5 psig. A gimbal that features a ring drive element enables efficient use of space. An actuation to drive the thruster may fit inside the ring drive element.
