Abstract: An apparatus, system and method for regulating fluid flow are disclosed. An apparatus for infusing fluid into a patient infusion apparatus includes a drip-chamber seat configured to receive a drip chamber; a tube seat configured to receive a tube fluidly coupled to the drip chamber, the tube including a plurality of conduits for fluid flow therethrough; a plunger configured to engage with the tube; and a user actuator configured to actuate the plunger.

Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A hand-held pointer control and input device has a case configured to be gripped by a right or left hand, with a curved back surface which fits against a palm of a hand gripping the device, a saddle-shaped surface configured to support and position a thumb of the gripping hand for operation of a cursor control device which protrudes from the top surface, and a curved button mounting surface positioned generally opposite the curved back surface and with at least one control button incorporated therein. The device enables control of a display cursor and input of control commands which correspond to a position of a cursor with a single hand and without contacting the device with a reference surface. A modular pointing stick and circuit board assembly is also provided.

Abstract: A system and method are provided for the automatic regulation of a balancing pressure to be applied to a rotor of a rotary screw compressor. The system includes a microprocessor which computes a balancing pressure to be applied to the rotor in response to an input of various compressor operating parameters such as suction pressure, discharge pressure, and percent capcity.
