331results about How to "Addressing Insufficient Control" patented technology

Described is an automatic control system for land (and possible marine) vehicles based on carrier phase differential GPS (CPGPS). The system relies on CPGPS to determine vehicle position and attitude very precisely (position to within 1 cm and attitude to within 0.1 DEG ). A system incorporates a technique to calculate and compensate for antenna motion due to vehicle roll and pitch. One aspect of the system utilizes an intelligent vehicle controller that recognizes and adapts to changing conditions, such as vehicle speed, implements towed by the vehicle, soil conditions, and disturbance level. The system provides the capability to control the vehicle on various paths, including straight lines and arbitrary curves. Also described is a technique for initialization and vehicle control using only a single pseudolite.

A rotary wing aircraft is provided having at least three rotor pairs. Each rotor pair has an upper rotor and a lower rotor. During operation, the upper rotor and lower rotor rotate around a shared rotor axis with the upper rotor rotating in a first direction and the lower rotor rotating in an opposite direction By independently controlling the speed of rotation of each upper rotor and each lower rotor the aircraft can be made to ascend, descend, move forward, move backward, move side to side, yaw right and yaw left by only varying the relative speeds of rotations of the upper rotors and lower rotors.

A method and apparatus for steering of a flexible needle into tissue using a steering robotic platform for manipulation of the needle shaft, and by use of a semi-active arm for locating and orienting of the steering robot on the patient's body. As opposed to other steering methods, the robot does not hold the base of the needle, which is its proximal region, but rather grips the shaft of the needle by means of a manipulatable needle gripping device, near its distal end. The needle gripper attached to the robotic platform may be equipped with a traction assembly to provide motion to the needle in its longitudinal direction, such that it co-ordinates the entry of the needle with the desired entry angle. The gripping of the needle at its distal end, close to its insertion point, provides the needle manipulator with a low profile, with concomitant advantages.

A reverse osmosis composite membrane that has a high salt rejection, a high water permeability, and a high fouling tolerance, and permits practical desalination at a relatively low pressure is provided by coating the surface of a reverse osmosis membrane of aromatic polyamide with polyvinyl alcohol (PVA), for example, and controlling the surface zeta potential of the separation layer within±10 mV at pH 6. This reverse osmosis composite membrane is electrically neutral and controls the electrical adsorption of membrane-fouling substances having a charge group present in water. Therefore, a high separation property can be maintained without fouling the membrane even if water containing a surfactant or a transition metal component is supplied as raw water.

A distributed, digital, network-based, streaming video solution allows users to view live streaming digital video from multiple video sources in multiple operating rooms at any location connected to a network. One or more video sources in an operating room are connected to a streaming video encoder capable of converting the video to a network packet stream. Once the digital video stream is available on the network, it may be accessed and routed through the use of a streaming video control server. The streaming video control server is responsible for user authentication and authorization and web page access for remote viewing and video source selection by users. The control server also provides audit logging services, operating room selection and overall system resource allocation. The video control server also provides a network-based remote control interface, which enables other systems to communicate on the streaming video network, and allows for remote control of visualization from an integrated operating room control system, and provides the ability for one operating room to look into other operating rooms.

In a 2-motor drive mode with connection of both motors to a driveshaft by means of a transmission, a hybrid vehicle sets torque commands of the motors to make a work performed by the second motor substantially equal to a work performed by the first motor and to ensure output of a torque equivalent to a preset torque demand to the driveshaft. This arrangement connects both motors to the driveshaft by means of the speed change-transmission assembly and ensures continuous output of a relatively large torque.
