A carriage assembly for controlling a steering wire steering mechanism within a flexible shaft, for use in gastrointestinal tract surgery, comprises a plurality of selectably engageable motors, including two drive motors for selectably rotating drive shafts of a surgical attachment, two steering motors mechanically communicating with corresponding pulleys around which are coiled directional steering wires communicating with a flexible shaft to enable the selective direction of the flexible shaft within a spatial plane, wherein within the assembly housing the steering motors travel on a steering motor carriage and the pulleys travel on a pulley carriage which is biased by a spring means away from the interior wall of the housing, which biases the steering wires toward a taut state. The bias can be overcome by a carriage motor mechanically communicating with the pulley carriage to cause the flexible shaft to go limp. Also disclosed are a series of surgical attachments which may be coupled to and utilized in conjunction with the carriage assembly.

Control method and control unit for impact type screw fastening device

An object is to improve accuracy of tightening torque and to shorten time necessary for fastening a screw in an impact type screw fastening device that uses an electric motor as a rotation driving source. A control method for the impact type screw fastening device that uses an electric motor as a rotation driving source includes the steps of driving the motor to rotate by supplying current to the motor intermittently so that torque exerted on a load by rotation of the motor becomes like pulses on the time axis, and controlling the current of every time of each pulse so that an increment of every time of each pulse of the torque after the torque reaches a target approach torque TQN that is a first set value becomes smaller than that before it reaches the target approach torque TQN.

Point of interest spatial rating search method and system

The present invention is directed to a system and method for searching and retrieving location information associated with one or more points of interests, whereby the search criteria can be dependent upon the location of a point of interest with respect to the the real-time position of the user, and any preferences or search restrictions selected by the user, such as rating information about the point of interest. Upon selecting a point of interest from the search result, the user is then given further information regarding the selected point of interest, including but not limited to directions for traveling to the point of interest. Additionally, the present invention can provide to the user a proximity notification once the user is within a certain distance from the point interest. Finally, while at a point of interest, the user can provide to the system information regarding the point of interest, such as rating of the food of a restaurant, without having to specifically identify the point of interest as the system can self-identify the point of interest by using the position information of the user.

Robotic surgical device

Described herein is a robotic surgical device configured for performing minimally invasive surgical procedures. The robotic surgical device comprises an elongated body for insertion into a patient's body through a small incision. In one variation, the elongated body houses a plurality of robotic arms. Once the distal portion of the elongated body is inserted into the patient body, the operator may then deploy the plurality of robotic arms to perform surgical procedures within the patient's body. An image detector may be positioned at the distal portion of the elongated body or on one of the robotic arms to provide visual feedback to the operator of the device. In another variation, each of the robotic arms comprises two or more joints, allowing the operator to maneuver the robotic arms in a coordinated manner within a region around the distal end of the device.

Auto-exposure method using continuous video frames under controlled illumination

An adaptive strobe illumination control process for use in a digital image capture and processing system. In general, the process involves: (i) illuminating an object in the field of view (FOV) with several different pulses of strobe (i.e. stroboscopic) illumination over a pair of consecutive video image frames; (ii) detecting digital images of the illuminated object over these consecutive image frames; and (iii) decode processing the digital images in an effort to read a code symbol graphically encoded therein. In a first illustrative embodiment, upon failure to read a code symbol graphically encoded in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the exposure time (i.e. photonic integration time interval) is automatically adjusted during subsequent image frames (i.e. image acquisition cycles) according to the principles of the present disclosure. In a second illustrative embodiment, upon failure to read a code symbol graphically encoded in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the energy level of the strobe illumination is automatically adjusted during subsequent image frames (i.e. image acquisition cycles) according to the principles of the present disclosure.

Sample detection to initiate timing of an electrochemical assay

An electrochemical assay includes a method for determining with great accuracy the time at which an applied sample bridges a gap between the electrodes of an electrochemical cell. The method involves applying a constant small current across the gap, while monitoring the potential difference between the electrodes. The time at which the sample bridges the gap is marked by a sharp drop in the potential. A constant voltage is applied after the sample is detected, and the current and / or charge through the sample is monitored over a period of time. From the measured current or charge, the analyte concentration of interest can be calculated.

Exposure apparatus and device manufacturing method

Liquid is supplied by a supply mechanism to a space between a lens and a wafer via a supply nozzle on one side of the lens, and the liquid is recovered by a recovery mechanism via a recovery pipe on the other side of the lens. When the supply and the recovery of the liquid are performed in parallel, a predetermined amount of liquid (exchanged at all times) is held between the lens and the substrate on the stage. Accordingly, when exposure (pattern transfer on the substrate) is performed in this state, an immersion method is applied and a pattern is transferred with good precision onto the substrate. In addition, in the case the liquid leaks out from under the lower edge of a peripheral wall, the liquid that could not be recovered is recovered by an auxiliary recovery mechanism via a slit. And, by such operations, the substrate is freed from the residual liquid on the substrate.

Stage device and exposure apparatus

A stage device suitable for exposure apparatus used to produce semiconductor devices, is movable in an area wider than the measurement area of interferometer for position measurement, and is capable of measuring the position with high precision. When a movable stage moves from the position where the laser beams from laser interferometers are not applied into the measurement area of the laser interferometer, the position of reference mark is measured by a wafer alignment sensor, and the measurement value measured by the laser interferometer is corrected based on the results of the measurement by the wafer alignment sensor. When another movable stage enters the measurement area of the laser interferometer, the position of the reference mark is similarly measured by a wafer alignment sensor, and the measurement value measured by the laser interferometer is corrected based on the results of the measurement by the wafer alignment sensor.
