Abstract:
A torque production vehicle includes a plenum body having a wall with a central port and a radial port formed within the wall, an impeller disposed within the plenum body to move air through the central port, an engine coupled to the impeller to rotate the impeller about an axis, at least one arm coupled to the plenum body, and a plurality of foils disposed in the radial port to direct air about the plenum body to provide a torque force about the plenum body.
Abstract:
A counterpulsation device that operates without the use of compressed air or pressurized gas includes at least one inflatable cuff that is adapted to be placed about a selected portion of the patient's body. A first conduit connects the inflatable cuff to an air transfer device so that noncompressed air can be transferred from the air transfer device to the cuff through the first conduit to inflate the cuff. A second conduit connects the cuff to the air transfer device so that air can flow through the second conduit to deflate the cuff. The system is controlled using a computer-based controller that requires a series of initialization procedures before it will operate the system. A patient profile database includes historical treatment data for each patient and is automatically updated with each counter pulsation therapy session.
Abstract:
An apparatus and method for automated harvesting are providing. The apparatus includes a mechanism for cutting the stalks of plants being harvested adjacent the ground. An inclined conveyor grasps the cut stalks and elevates them above the ground. The conveyor includes two corners that serve to partially invert the plants as they are conveyed. Cooperating inversion disks at the end of the inclined conveyor complete the inversion of the stalks through 180.degree.. After the stalks are inverted they are conveyed on a spacing and notching conveyor. The spacing and notching conveyor operates at a slower speed than the inclined conveyor so as to reduce the spacing between the inverted plants to a distance appropriate for curing. A notching mechanism cuts two opposed, laterally spaced notches in the stalks of the inverted plants as they are conveyed. The plants are then substantially continuously fed by a feed conveyor so that the notched stalks are received and held within a slotted track of a portable frame allowing subsequent curing. The apparatus also includes mechanisms for (1) dispensing a portable frame from a magazine rack of frames on the harvester to a position for receiving plants; (2) indexing the frame relative to the feed conveyor so as to allow ordered, sequential filling of multiple slotted tracks on the frame; and unloading filled frames from the harvester. The notching and indexing mechanisms as well as a method of harvesting are also claimed.

Abstract:
According to one embodiment, code embodied in a computer readable storage medium is configured to generate a checklist for a vehicle by receiving a measured value obtained from at least one sensor configured on the vehicle, setting a parameter value that is associated with the at least one sensor to the measured value, and displaying the checklist on a user interface. The checklist has a number of parameter fields associated with various operating characteristics of the vehicle.
Abstract:
A guidance control system for a harvester or like machinery includes a steering linkage operatively connected to at least one ground engaging wheel. Harvester steering is controlled through the linkage by either an operator controlled steering wheel or a sensor responsive self-steering mechanism. The sensor responsive self-steering mechanism includes a guide assembly pivotally mounted to the harvester. The guide assembly includes a pair of laterally spaced, cooperating tines that define a path therebetween for plants being harvested. A sensor positioned on each tine senses the position of plants as they are harvested. A control circuit is responsive to the sensors to selectively impart movement to the steering linkage to self-steer the harvester. The control circuit includes a main valve controlled by the operator controlled steering wheel and a secondary valve controlled by the sensors. An auxiliary feed line leads from the main valve to the secondary valve. When the operator utilizes the steering wheel control, an interrupter blocks hydraulic flow through the auxiliary line from the main valve to the secondary valve. Thus, operator controlled steering input overrides the sensor responsive self-steering for maximum safety. The guidance control system also eliminates harvester wander back and forth across a row by substantially preventing overcompensation by the sensor responsive self-steering.
Abstract:
An improved seal design for a Surface Effect Ship, having an inflatable ir seal member, and outer seal member composed of a pliable sheet material scrollably affixed to the hull fore and aft of the inner seal member. The seal may be retracted for hullborne operation by deflating the inner seal member and scrolling the outer seal member tight to hull. The inner seal member has transverse webbing for stability. The outer seal member is periodically scrolled foreward to expose an unworn section to the water surface thereby reducing seal failure due to wear.
