摘要:
A bi-directional flow catheter for insertion into the body of a patient for the simultaneous introduction into and withdrawal therefrom of fluid. The catheter includes a primary tube having open distal and proximal ends, and a pair of branching tubes, each of which branch from a different side of the primary tube. The primary tube also has an opening in one side thereof to allow introduction of fluid. An elongate trocar/valve member is disposed in the primary tube and is movable longitudinally therein between an insert position and a flow position. One end of the trocar/valve member tapers to a cutting edge which protrudes from the opening in the distal end of the primary tube when the member is in the insert position. The trocar/valve member is formed to prevent communication between the side opening and the opening in the distal end of the primary tube, and to cover the passageways between the primary tube and respective ones of the branching tubes when the member is in the insert position. When the member is in the flow position, the cutting end thereof is withdrawn from the distal opening and communication is allowed between the side opening and one of the branching tubes and between the distal opening and the other of the branching tubes to thereby allow simultaneous introduction of fluid into and withdrawal of fluid from the body of a patient.

Single and multiple cell batteries are provided with built-in controllers that monitor the cell or cells and provide a safety disconnect when certain monitored conditions are detected by the controller. Preferred single and multiple cell batteries have their cell or cells within a container having a positive terminal and a negative terminal. The built-in controller monitors the cell or cells for each of the following conditions: over temperature, short-circuit, overcharge, and over-discharge and the controller provides a safety disconnect when one of the monitored conditions exist. A multiple cell battery includes a built-in controller that monitors the temperature of the cells and provides a safety disconnect that electronically disconnects all of the cells when at least one of the cells exceeds a predetermined temperature, or a controller that monitors the state of charge of each of the cells and individually controls the charge cycle of each of the cells, or a controller that monitors the temperature of the cells and to provides a safety disconnect when at least one of the cells exceeds a predetermined temperature.

Apparatuses and methods are provided that minimize the effects of dark-current pulses. For example, in one embodiment of the invention, a method is provided where a first pixel is struck (i.e., a primary pixel). Pixels struck within a fixed time frame after the primary pixel is struck are referred to as secondary pixels. After a short fixed time frame has expired, the number of primary and secondary pixels is added. If the count exceeds a threshold, the primary pixel was activated by the first (or early) photon from a true gamma event. If the threshold is not met then it is likely the primary pixel generated a dark pulse that should be ignored.

In one aspect, the present invention provides an order slicer that receives an order that to trade a financial instrument. The order associates a trading strategy with said order. The trading strategy is replaceable. In another aspect, an interface accepts a trading strategy of an order to trade a financial instrument. A transmitter transmits the trading strategy to an order slicer.

摘要:
By supplying auxiliary power to a blade's optional components, instead of polling the blade for the power requirements of a fully configured module, each installed component can be individually polled and the values summed to produce a more accurate value representing the actual power needs of a blade system prior to booting.
