A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.

An intelligent rechargeable battery pack having a battery management system for monitoring and controlling the charging and discharging of the battery pack is described. The battery management system includes primary and secondary protection circuits for monitoring the charging and discharging of the battery. Individual battery cells forming the battery pack are connected by a main bus to a connector for connection to a battery charger or a device to be powered, and the main bus may be interrupted by a switch controlled by the battery management system to prevent damage to the battery during charging or discharging of the battery.

A lighting apparatus and method of use provides for increasing the visibility of a cyclist. The lighting apparatus includes a plurality of lights that may be arranged in a linear array to facilitate attachment to elongate members of a bicycle. The plurality of lights can be mounted on a substrate that is received in a mounting member, which in turn can be attached to a bicycle. Alternatively, the lighting apparatus may be formed integrally as part of a bicycle. Attachment of one or more lighting apparatuses to a bicycle can provide for increased visibility of a cyclist from the front, the rear, or the side, and may be configured to provide increased visibility when it is either dark or light outside.

A network management system. In particular implementations, a method includes establishing a persistent session with one or more network management servers, where each persistent session is identified relative to a session identifier; authenticating one or more clients requesting access; receiving, from a client, a request to access a selected network management server of the one or more network management servers; generating a ticket for the client; and transmitting a redirection message to the client, where the redirection message identifies the selected network management server and includes the ticket and the session identifier corresponding to the selected network management server.
摘要:
A rechargeable power cell having no voltage across its positive and negative power terminals unless the power cell is inserted into a device configured to accept the power cell is described. The power cell includes a battery management processor and battery insertion detection circuitry that cooperate to determine when the power cell is inserted into the device and then drive an electronic switch to provide for conduction of current from the power cell to the positive terminal of the cell.
摘要:
An optical absorption gas sensor comprising a body having an internal wall which defines a chamber, at least one aperture in the body through which a gas sample can enter the chamber, a light source, at least one reflector, a detector assembly which extends into the chamber and has a first side and an opposite second side, a detector which measures light which is incident at least a range of angles on at least a part of a first surface of the detector assembly on the first side of the detector assembly, wherein the light source is located within the chamber on the second side of the detector assembly, the whole being configured such that light from the light source passes through the gas sample and is reflected around the detector assembly, by the at least one reflector, onto the detector.
摘要:
A method of locating a subsea structure beneath a floating deployment vessel for deployment to a seabed including at least the steps of: (a) transporting the subsea structure on a floating transporting vessel near to the deployment vessel; (b) lowering the transporting vessel to allow the subsea structure to float; (c) relocating either the transporting vessel or the subsea structure to allow the subsea structure to be separate of the transporting vessel; and (d) locating the subsea structure beneath the deployment vessel using one or more buoyancy elements with variable buoyancy.
