Abstract: A turbine which uses fluid pressure to turn a shaft in a manner that does not allow for cavitation to be created.

Abstract: A two-stroke engine with valves near bottom dead center that are adapted to prevent intake charge from exiting exhaust ports, wherein the valves are actuated by air pressure difference.

Abstract: A new engine which incorporates the advantages found in a two-stroke with the advantages found in a four-stroke engine combined.

Abstract: A two-cycle internal combustion engine with rear compression chamber, other than that of a crank case. This present engine has valves that can be screwed on the engine block near top dead center, and is actuated by air pressure. This present two-cycle engine uses an oil sump similar to that of a four-cycle engine, which eliminates the need to premix oil with the fuel. This present engine has a stationary piston which operates within a movable piston to form a rear-compression chamber. The movable piston has ports near its crown to transfer charge to the combustion chamber. The movable piston also has ports near bottom of its skirt to allow the fuel and air mixture to enter the rear compression chamber. This engine has a piston seat which is adapted to connect the movable piston to the connecting rod.

Abstract: A cam and follower apparatus adapted to translate the force of a piston to turn the shaft of an engine. The cam profile is made of three intersecting circles allowing for one follower to be near top dead center while another follower is near bottom dead center. The surface of the follower is a circle which shares the same center point and radius with the circles of the cam profile. The surface of the follower also closely intersects the axis of the follower preventing the follower from spinning like a roller follower. The follower can therefore spread the force from the piston to a wider area on the cam for longevity.

Abstract: A two-cycle internal-combustion, rear compression, engine with variable valve timing, activated by air pressure and located at about top dead center. This engine has a variable compression ratio combustion chamber that is based on the speed that this engine is running at. This engine further operates with variable fuel and air ratio using air pressure. This engine runs lean whenever the throttle body is not fully open. This engine uses air pressure difference and throttle body position to constantly adjust fuel and air ratio for optimum efficiency. The synergy of this engine configuration allows for operator to be alerted when it is time to upshift and maintain maximum efficiency. This engine will prevent excessive speed and run at optimum efficiency by automatically running lean whenever engine speed is too high. This engine also runs on compression ignition, without electronics which is susceptible to electromagnetic pulse.

Abstract: An adjustable wearable ergonomic split keyboard and mouse data input device is provided that includes two hand modules. Data and command input keys are provided in each module and arranged on fingerlike components which are attached to a palm support structure . Each key mounted on top of a fingerlike component is generally adjustable to the operator's wish and may be locked at a preferred position. A thumb section, located adjacent to the operator forefinger position, comprises a thumb support structure, a pointing device and a relatively flat area which may include the spacebar key or a group of command keys. The palm support is shaped with angles and curves which provide counter pressure points to the palm. Straps and arm support components are optionally attached to the keyboards for wearability.

Abstract: An adjustable wearable ergonomic split keyboard and mouse data input device that includes two hand modules as shown in FIGS. 4A and 4B. The keys are arranged in rows (FIG. 2A) with sets of keys where each is flexibly assigned to a finger of the operator. The keys of the keyboard are arranged on fingerlike components (FIG. 9E) which are attached to a palm support structure (FIG. 10E). Each key (80) mounted on top of a fingerlike component is generally adjustable to the operator's wish. Such configuration will remain locked during operation due to a self lock mechanism (44, 45, and 14). The operator can change the settings with two fingers by pressing on a button (43) and twisting up or down. The operator can adjust each key to a desired distance (FIG. 2C) from the fingers to achieve maximum comfort. A thumb section (FIG.
