Abstract: In a method of detecting a mobile station that is not following a power control command, for each time slot, a received signal-to-interference ratio (SIR) value of the mobile as measured by a given base station is compared with a given average SIR target value. An error metric may be generated for each slot based on a difference between the measured SIR and average SIR target values. The generated error metrics may be averaged over a given time duration to determine at least one (or more) average error value(s), and the mobile station is determined as violating a power control command if the at least one or more average error value(s) exceed a given threshold.

Abstract: A method for interchanging information data between an electrical load and an item of equipment arranged between the load and the electric power grid is disclosed. An energy storage device located in a load recognition unit associated with the load is charged during a load recognition phase at start-up of the load. After the energy storage device is charged, data stored in the load recognition unit are repeatedly transmitted in form of a data burst to the item of equipment located between the load and the electric power grid. The data burst includes a preamble and load data; whereby the transmission is controlled by a controller in the load recognition unit.

Abstract: The dispersion of metal-element containing additives with hydrogen storage particles of the family of hydrogen-rich materials, M?xM?yNzHd as specified herein, markedly lowers the temperature at which hydrogen is removed from the particles. For example, the dispersion of additives containing one or more of iron, nickel, palladium, or platinum with particles of Li50B17N33H133 provides a composition from which hydrogen is readily removed by heating. Use of these metals as their chloride salts makes particularly effective hydrogen release additives.

Abstract: A hydrogen delivery system for a fuel cell is provided that uses hydrogen as a reactant. A fluid storage vessel contains a hydrogen storage material that reversibly releases and stores hydrogen gas. The released hydrogen gas exits the fluid storage vessel, is pressurized by a fluid pressurization device, and then stored in a ballast vessel. The hydrogen gas is delivered as a reactant to the fuel cell from the ballast vessel at a pressure greater than or equal to the operating pressure of the fuel cell. Variations of the above described hydrogen delivery systems are further disclosed, as well as methods of delivering hydrogen to a fuel cell.

Abstract: In a system of communication, a sending node sends a message to a receiving node, which NAKs unsuccessful transmissions. The sending node screens the NAKs to determine if they were sent before the receiver could receive previous transmissions of the same data NAKed. One screening technique is based on an estimated round trip time of a message. Another alternate technique looks a flag in the NAK that synchronizes the sender and the receiver.

Abstract: ntion is directed to the management of data burst requests. In iethod of the invention operates to determine a measure of one or parameters, which in an advantageous embodiment are the input z amount of data available in the input data buffer at the beginning t. The invention then proceeds to the selection of an operating data burst as a function of the input data parameter measures. In an nbodiment, the operating data rate is determined by computing the red data rate as a function of the input data rate and the data content fer at the beginning of the data burst, with the operating data rate lowest supported system data rate that is equal to or greater than the ed data rate. In a further step, the invention proceeds to a selection r the data burst from the burst durations supported by the wireless ction of the selected operating data rate and an end-of-burst data er.

Abstract: A communication system selection algorithm (SSA) implemented by a mobile station chooses between available systems to select a system to serve the mobile station. During initialization, the SSA causes the mobile station to scan the environment and compare available communication systems to determine the best system to provide service. After an initial system is chosen, the SSA causes the mobile station to continuously, or at discrete time intervals, scan the environment for available systems, thus allowing for a seamless switch to an available system whenever a handoff is desired. The SSA chooses the best available system based on conditions such as bit rate and cost of each available system and applying preference rules defined by a service provider and/or user of the mobile station.

Abstract: A device for emitting high-frequency signals, which has a modulator for the amplitude shift keying of input signals, a Class-E amplifier and a transmitting antenna. Such a device can be used in an identification system as a component of a read/write device, from which modulated data signals are transmitted to a mobile data carrier. Input signals (DS) are subjected to amplitude shift keying by controlling a plurality of parallel-connected tri-state outputs of a digital integrated circuit (IC) with a control unit (CTR). The tri-state outputs switch a transistor of the Class-E amplifier at the carrier frequency. As a result, a nearly harmonic current with a constant amplitude is generated in the transmitting antenna.

Abstract: A burner for use in a combustion system of a heavy-duty industrial gas turbine includes a fuel/air premixer having an air inlet, a fuel inlet, and an annular mixing passage. The fuel/air premixer mixes fuel and air into a uniform mixture for injection into a combustor reaction zone. The burner also includes an inlet flow conditioner disposed at the air inlet of the fuel/air premixer for controlling a radial and circumferential distribution of incoming air. The pattern of perforations in the inlet flow conditioner is designed such that a uniform air flow distribution is produced at the swirler inlet annulus in both the radial and circumference directions. The premixer includes a swozzle assembly having a series of preferably air foil shaped turning vanes that impart swirl to the airflow entering via the inlet flow conditioner.

Abstract: In a method for visualizing and processing a value assembly process, the value assembly process is visualized as a set of value assembly lines (VAL) arranged on different hierarchy levels. Each value assembly line receives value packages via input interfaces and consolidates these to form a value added package (VAP), an added value being created, and makes the added value package available at an output interface. The added value package can be used by a value assembly line of a higher-order hierarchy level as input value package. Likewise, the input value packages of the value assembly lines can be value added packages made available by lower-order value assembly lines, the lower-order value assembly lines being value assembly lines of a lower-order hierarchy level. All value assembly lines and all value packages have an identical structure; only the processed data differ from one another.

Abstract: Testcases are run to test the design of an integrated circuit. The coverage of the testcases is evaluated and compared against one or more microarchitecture models that define the behavior of a portion of the integrated circuit. If the coverage of the testcases is not adequate, new testcases are generated to test the previously untested behavior specified in the microarchitecture models.
