Abstract: A method for conducting the motion of a transporter under riderless conditions. The transporter has two laterally disposed primary wheels. In accordance with the method, an input is received via a user input disposed on the transporter and a control signal corresponding to the input received is generated. Then a torque is applied to the laterally disposed wheels so as propel the transporter on the basis of at least the control signal. The control signal may correspond to either a commanded torque or to a commanded transporter velocity. The torque may include coadded terms where the terms are, respectively, proportional to the control signal, to a counteracting artificial friction proportional to the common velocity of the wheels, and a term proportional to the differential rotation of the wheels to facilitate turning of the transporter.

Abstract: A controller and methods for controlling the speed of a vehicle having an electric motorized drive is provided. In one embodiment, a method involves determining a steady state average torque and a torque during acceleration or deceleration of the vehicle traveling over an underlying surface. Speed of the vehicle is controlled based on the steady state average torque, the torque during acceleration or deceleration the measured regeneration current generated by a motorized drive arrangement of the vehicle that applies torque to at least one ground-contacting element of the vehicle for traveling over the underlying surface, weight of the vehicle and payload, the torque applied to the ground-contacting element, acceleration of the vehicle and the speed of the vehicle.

Abstract: A transporter that includes a platform for supporting a load and at least one primary ground-contacting element. The transporter includes an actuator for applying torque to the at least one primary ground-contacting element for propelling the transporter with respect to a surface. The transporter also includes a controller for controlling the actuator, the controller includes an input for receiving specification by a user of a desired direction of travel based on a position of a member with respect to a fiducial axis, a differentiator for calculating a rate of change of the position of the member with respect to the fiducial axis, and a processor for generating a yaw command signal based at least on the position of the member and the rate of change of the position of the member which is weighted based on the level of experience of the user.

Abstract: The present invention generally relates to a system and method for distributing an open transaction instrument. The system includes the steps of: accessibly offering for sale, in a retail environment, the open transaction instrument; selling a selected open transaction instrument; and enabling the use of the open transaction instrument. The transaction instrument may be, for example, an open pre-paid card. Furthermore, accessibly offering the open pre-paid card for sale, in one exemplary embodiment, is performed by hanging the pre-paid card on a rack. The distribution of the open transaction instrument may also comprise the step of sending a message, in substantially real time, causing the pre-paid open transaction instrument to be funded but not activated. Also, in accordance with further exemplary embodiments of the present invention, an issuer system is suitably configured to leverage existing infrastructure for inventory and related processes.

Abstract: A method for fore-aft stabilization of a vehicle for motion in a specified direction over an underlying surface. The vehicle has at least one forward wheel and at least one aft wheel, and the forward wheel is characterized by a force normal to the instantaneous direction of motion of the vehicle. A motor actuator drives each aft wheel, and a controller governs the motor actuator or motor actuators in such a manner as to dynamically stabilize the vehicle, according to a uniform control law, when the forward wheel is in contact with the underlying surface or not. A torque is applied to the aft wheel on the basis of vehicle pitch or the force on the forward wheel normal to the direction of motion. Additionally, a periodic rotational modulation may be applied to the aft wheel, and a stabilizing torque provided based on a detected response, either of vehicle pitch or of normal force on the front wheel.

Abstract: A surgical tool for endoscopic suture placement which permits a surgeon to place controlled and precise internal ligatures. The tool utilizes a drive rod including an articulating or deflecting portion. When forced to an extended position, the deflecting or articulating portion forms a hook or J-shaped needle, the tip of which can be used to accurately position the suture.

Abstract: A double needle ligature device for efficiently creating a loop suture for closing wounds, such as trocar wounds. The device preferably includes a double needle assembly to ensure that the suture is positively held in place during needle retraction.

Abstract: A method and apparatus for preventing accidental manual rotor reversal in a peristaltic pump is provided. A peristaltic pump may be provided with a hand crank or the like to drive a rotor assembly of the pump manually in the event of failure of the electric motor drive of the pump. An indicator may provide information to the pump operator to inform the operator of the direction in which the pump was rotating when last driven by the electric motor. Further an alarm device may alert the operator when the operator is attempting to rotate the pump in the direction opposite the direction in which the pump was rotating when last driven by the electric motor or the direction last selected by the operator before loss of power.

Abstract: A device for irrigation and suction removal of blood, bodily fluids and debris from a body cavity primarily during laparoscopic procedures and surgery. The device contains a single piston slidably disposed in a passage contained in a housing having two inlets and a single outlet. The piston includes a central seal with two valve portions positioned on each side of the central seal. Piston positioning means are provided to move the piston to align the valve portions within the housing with the outlet and one of the inlets, while the other inlet is simultaneously sealed off. Thus, the piston may be moved from a neutral or shut-off position to an open irrigation position, or, alternately, moved from the neutral or shut-off position to an open vacuum position. The valve may also contain automatic biasing means for returning the valve from either the open-irrigation position or the open-vacuum position to the central shut-off position.
