An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.

The invention relates to a numerically controlled surgical stapling apparatus comprising a clamping assembly, a housing and a main body assembly arranged in the housing. An electric driving device is arranged in the main body assembly. The stapling apparatus is characterized by further comprising a numerical control device which comprises a control board, a display screen and a sensing device, wherein at least one memory chip and a control chip are arranged on the control board; and the display screen is capable of displaying the values of operation parameters and clock information. The electric driving device is capable of receiving a signal produced by the numerical control device and drives a nail magazine to move toward a nail anvil until a predetermined closing gap, and further causes a suturing nail to reach a predetermined forming height after firing the suturing nail. The numerically controlled surgical stapling apparatus provided in the invention is capable of performing accurate and safe control on the transmission steps and the operation actions and also of clearly displaying the operation parameters so that a doctor can know the whole surgery process; therefore, human-machine conversation is made possible.

Provided is a bipolar high frequency treatment device including a catheter tube insertable into a body through a treatment device passage of an endoscope; a first forceps blade and a second forceps blade at the top end of the catheter tube, which first forceps blade and second forceps blade can be opened and closed by operating from outside the body; a support member for supporting the first forceps blade and the second forceps blade so that the blades are able to open and close; and a voltage supplier for supplying a high frequency voltage to the first forceps blade and the second forceps blade, wherein the first forceps blade and the second forceps blade are electrically insulated with an insulating element.

An actuator system for actuating a valve in a subsea environment comprises a valve spindle that is arranged to be coupled to an electric motor. To provide for power to the motor, at least one local electrical storage unit is provided. The system also includes a control unit comprising switching means for controlling the power to the motor. The control unit includes an intelligent processor and is arranged to receive signals from external sensors measuring a number of external and internal parameters, The actuator is preferable housed in a modular cage for easy replacement.

Systems and methods for interruptible autonomous control of a vehicle. Autonomous control is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay, or prevented.

An integrated imager circuit having a monolithic array of single photon avalanche diodes (SPADs) for capturing an image of a scene when said scene is hit by an optical pulse. The array has a plurality of SPADs connected to 2D readout circuits which determines the intensity of the light reflected by the scene by counting the number of photons received by the SPADs during a period of time. A plurality of SPADs connected to 3D readout circuits determines the distance to the scene by determining the elapsed time between the emission of each pulse and reception of the corresponding reflected photons.

The invention relates to a remotely programmable personal medical device, in particular a programmable implantable medical device, e.g., a cardiac pacemaker, a defibrillator, a cardioverter or the like. In addition, the invention relates to an arrangement for remote programming of such a personal medical device and a method for remote programming of a programmable personal medical device.

A movable-vehicle security system includes a facial-recognition system including a scanner such as a television or infrared camera directed at the face of a person in the driver's seat, which system produces output control signals that are applied to enable or disable operation of the vehicle, with or without a key or other supplemental security system. In a particular embodiment, the system includes a camera mounted on the “third taillight” assembly (which is preferably mounted below the roof and inside the rear window), directed at the rear-view mirror, and coupled to a facial-recognition computer, which in turn is coupled (with appropriate security precautions) to an enabling element for the vehicle, such as a starter motor. In a further embodiment, the system can be coupled to various elements of the motive system to create an auto-starting car.

Registry verification is used in a mechanized store. A camera is used to count a first number of items taken by a user. The items are scanned to determine a second number of items. The first number of items is compared to the second number of items to reduce a likelihood of errors.
