Abstract:
A method of analysis of medical signals is presented which provides useful clinical information concerning the state of the myocardium during cardiopulmonary resuscitation (CPR). The analysis during CPR can be used to (i) identify the underlying rhythm, (ii) provide a measure of the efficacy of CPR, and (iii) to predict the outcome from a defibrillation shock.
Abstract:
A method and apparatus is provided for monitoring operations of a specified transaction server that has an associated network topology. One embodiment comprises the steps of defining a plurality of zones within the network topology, and assigning one or more monitoring agents to each of the zones, wherein each agent is adapted to selectively run synthetic transactions with the specified server. The method further comprises monitoring results of successive synthetic transactions carried out by the agents, in order to detect any errors associated with the successive transactions. In response to detecting a performance or an availability problem, selectively, that is associated with a particular synthetic transaction run by a particular one of the agents, one or more agents is dynamically scheduled to run synthetic transactions, wherein each scheduled transaction has a specified relationship with the particular transaction.
Abstract:
A method, apparatus, and computer instructions for identifying unsafe synthetic transactions and modifying parameters for automated playback. Bytecode instrumentation is used to dynamically observe the behavior of application code directly and identify each universal resource locator traversed and parameters passed in a transaction. The bytecode instrumentation may determine, based on the parameters passed, that a parameter in the current transaction is an unsafe parameter, and that the unsafe parameter is associated with a test parameter in a previously overridden transaction. If the unsafe parameter has an associated test parameter, the bytecode instrumentation may dynamically override the unsafe parameter in the current transaction with the test parameter in order to make the transaction safe for synthetic playback. In this manner, transactions may be scheduled for playback as usual, and the bytecode insertion methods ensure that the unsafe parameters in the transactions are automatically overridden for the user.
Abstract:
A network device checkout system is accessed by another program that powers off unused systems. The checkout system keeps track of the usage of various systems on a network so that only the systems that need to remain on for productivity will consume power, with systems in a check-in state being powered off. Records of system usage are stored in an associated database. Systems that are no longer being utilized are powered off.
Abstract:
A method of self-configuration of a network device having at least one network connection port, comprising the steps of, after booting of the network device, actively probing a network in which the network device is located and analysing data packets received on the port(s), attempting to determine a network configuration for all network connections the device can make according to information extracted from the received data packets, and configuring device settings according to the network configuration determined.
Abstract:
A network edge telephony device for local audio message insertion comprises a network interface for receiving data from and transmitting data to a network, and a user interface for receiving data from and transmitting data to a user, the data including data representing an audio signal, and processing means coupled to the network and user interfaces, the processing means comprising a mixer adapted to locally mix a call progress tone derived in dependence on an audio signal received from the network or user interfaces with a data stream representing a pre-recorded audio message. Also provided is user event processing means coupled to the user and network interfaces, which is adapted to detect feedback from the user and generate and transmit an event data signal to a remote server via the network interface.
Abstract:
A method of cleaning a deposition tool to control and minimize emission of environmentally deleterious materials includes the steps of: a) establishing a predetermined temperature in a processing chamber; b) providing a mixture of between 15 and 25 percent nitrogen trifluoride in helium at a mixture flow rate of more than 550 standard cubic centimeters per minute (sccm); c) establishing a high pressure of 1.5 to 9.5 torr in the processing chamber; d) establishing a plasma in the processing chamber, e) establishing a low pressure in the processing chamber of 2 torr or less; and f) establishing a plasma in the processing chamber. Instead of a two-step cleaning method, the method may alternatively be executed as a one-step cleaning method. Either method may be optimized by, among other things, providing 19% nitrogen trifluoride. The two-step method may also be optimized by providing a high pressure of about 7 to 9.5 torr and a low pressure of about 1.5 torr.
Abstract:
A product made by a substantially zero carbon emission process for making amorphous poly alpha olefins including, converting alkanes to olefin monomers ethylene, propylene, and 1-butene or combinations thereof using renewable electric power in an oxidative-coupling of methane plant including the steps of passing alkanes through an ethylene plant while adding oxygen, passing the first polymerization grade ethylene through a 2-butene plant, passing a first of the two 2-butene streams and one of the polymerization grade ethylene through a propylene plant, and passing a second of the two 2-butene streams through a 1-butene plant. The next step in the process for making amorphous poly alpha olefins includes polymerizing at least one of the polymerization grade alkenes which includes applying a temperature of 130 degrees Fahrenheit to 175 degrees Fahrenheit to at least one of the polymerization grade alkenes and scrubbing at least one boiler stack gases.
Abstract:
In an open chamber air gun, a round is gravity fed or magnetically fed into the open chamber and falls into the magnetic flux lines of a magnet disposed at the chamber. Due to the magnet, the round is pulled securely into the chamber and then remains momentarily held in place, blocking much of the air behind it and thus increasing the air pressure driving it. When the round moves down the barrel from the breech toward the muzzle, it quickly leaves the vicinity of the magnet and the magnetic drag ceases, after which the air pressure is free to drive the round to full velocity. High rates of fire and muzzle velocities are achieved with moderate air pressure and an action with no moving parts.
