A full-thickness resection system comprises a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism comprises an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another between a tissue receiving position and a stapling position and wherein a gap formed between the stapling head and the anvil is larger in the tissue receiving position than it is in the stapling position. A position adjusting mechanism is provided for moving the anvil and the stapling head between the tissue receiving and stapling positions and a staple firing mechanism sequentially fires a plurality of staples from the stapling head across the gap against the anvil and through any tissue received in the gap and a knife cuts a portion of tissue received within the gap. A control unit which remains outside the body is coupled to the stapling mechanism for controlling operation of the position adjusting mechanism and the staple firing mechanism.

An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.

An ultrasonic surgical system has an ultrasonic unit including an instrument operatively connected to an ultrasonic generator, wherein the instrument has an ultrasonic end effector on the distal end of a shaft. The system further includes a positioning unit including a movable arm adapted for releasably holding the instrument, whereby an operator may direct the positioning unit to position the end effector at a surgical site inside a body cavity of a patient for performing a plurality of surgical tasks. The system further includes a control unit operatively connected to the ultrasonic and positioning units, wherein the control unit is programmable with a surgical subroutine for performing the surgical tasks. The system further includes a user interface operatively connected to the control unit for initiating an operative cycle of the surgical subroutine such that the surgical tasks are automatically performed during the operative cycle.

A fuel cell includes a spark initiator configured to initiate spark events, and a fuel level monitoring system configured for monitoring the fuel level in the fuel cell and indicating the monitored fuel level to a user. Included in the fuel level monitoring system is a programmable control unit configured to control the spark initiator and to count the spark events initiated by the spark initiator, to compare a number of spark events with at least two predetermined ranges of spark events, and to determine the fuel level in the fuel cell based on the determinations. An indicator controlled by the programmable control unit is supplied for providing the user with an indication of the fuel level in the fuel cell.

A high-speed surgical handpiece (10) suitable for vitreoretinal surgery having a cutter (42) and actuators (36). The cutter (42) is a guillotine-type cutter activated by an array of leveraged piezoelectric actuators (30) that receive a driving signal from a driving controller. The controller can have control and display units with a plurality of input mechanisms receiving input from a user who selects a desired cutting rate and frequency for the cutter. The control unit produces a piezoelectric actuator output signal based on the inputs received. Fast cutting rates with reduced duty cycle as well as a proportional mode of operation are available, allowing slow controlled cutting action, for example proportional to depression of a foot-pedal (74). Low degrees of vibration and noise generation are produced.

Apparatus (10) is provided that includes at least one sensor (30), configured to sense a physiological parameter of a subject (12) and to sense large body movement of the subject (12), an output unit (24), and a control unit (14). The control unit (14) is configured to monitor a condition of the subject (12) by analyzing the physiological parameter and the sensed large body movement, and to drive the output unit (24) to generate an alert upon detecting a deterioration of the monitored condition. Other embodiments are also described.

In a mobile communicating system, a mobile terminal has a position information detecting unit for detecting position information, a position information transmitting unit for transmitting the position information to an information center, an up-load data transmitting unit for transmitting up-load data to the information center and an information/service utilizing unit for utilizing information/service from the information center, whereas the information center has an accumulating unit for accumulating information/services, a retrieving unit for receiving the position information from the mobile terminal to retrieve the information/services in the accumulating unit, an accumulation controlling unit for accumulating the up-load data in the accumulating unit, and an information/service transmitting unit for taking out the information/service retrieved by the retrieving unit from the accumulating unit and transmitting it to the mobile terminal, thereby providing not only map information showing the current position of the mobile terminal but also information of facilities on the map to the mobile terminal.

The present invention provides a device and method for antenna matching applied in a transceiver. Wherein, the transceiver has a transmission module and a receiving module. The antenna matching device includes a matching circuit, a duplexer, a circulator, a control unit, and a coupler. Wherein, the matching circuit adjusts the matching impedance according to an adjusting signal and generates a reflection signal. The duplexer receives the reflection signal and a receiving signal and respectively sent the received two signals to the control unit and the receiving module according to their frequencies. The control unit, according to the reflection signal, estimates the adjusting signal for adjusting the matching circuit to an optimal state of the load impedance of the matching antenna, such that the antenna gain may is maximized, and a best efficiency is obtained no matter during receiving or transmission.
