Abstract: A combined circulation condenser for a steam cycle apparatus is disclosed. The steam cycle apparatus includes a steam generator with a port for receiving a fluid. The steam generator presents heat to the fluid to generate steam that is directed out another port, which presents the steam to a turbine to generate electrical power. The turbine has an outlet that directs an exhaust steam into a condenser. A fluid flow system is inside the condenser, which directs cooling water along a pathway through the condenser so that the cooling water cools the exhaust steam, forming condensate. A condensate pump collects and pumps the condensate along another pathway through the condenser so that the condensate can additionally cool the exhaust steam. Simultaneously, the exhaust steam warms the condensate. This pathway directs the condensate to a feed pump, which pumps the condensate back to the steam generator through the generator's input port.

Abstract: A flow monitoring system includes a pipe for transporting a fluid therethrough. An optical fiber generally spirals about the pipe along a longitudinal portion having a predetermined length to serve as a single transducer for detecting flow information from the longitudinal portion. A linear polarizer/analyzer circuit communicates with the optical fiber. A light source communicates with the linear polarizer/analyzer circuit and generates a light signal along the optical fiber at a frequency greater than a period of a disturbance to flow past the predetermined length of the transducer. A reflector is disposed along the optical fiber for reflecting the light signal along the optical fiber. An optical detector communicates with the linear polarizer/analyzer circuit. The optical detector determines from the light signal dynamic events along the optical fiber indicative of flow disturbances passing by the transducer.

Abstract: In a method and system for controlling base station processing unit overload and buffer overflow in a unified manner, one or more processing units of the base station are monitored to determine if the processing unit(s) has entered an overload condition. If so, on a per flow basis, the system generates an advertise window for controlling the amount of data in the data flow, as transmitted to the processing unit from an upstream entity. The advertise window is generated taking into consideration both processor overload and buffer overflow factors. By incorporating these factors, the advertise windows collectively serve to limit both processor overload and buffer overflow, on a system wide basis.

Abstract: A packet data load generator (PDLG) system, and method for testing the PDLG system, includes a Linux-based computer terminal having multiple 1x-EVDO wireless interface cards, e.g., Sierra Wireless AirCards®, directly interfaced therewith. PCI-to-PCMCIA adapter cards are used for connecting the wireless cards to the terminal. The terminal also includes a Linux control program for controlling the multiple wireless cards on a single terminal. In operation, the wireless interface cards are controlled to establish multiple simultaneous 1x-EVDO calls between the terminal and a 1x-EVDO wireless network, e.g., each wireless interface card supports one call with the network. Packet data is transferred between the terminal and the network, in effect simulating a multiple 1x-EVDO call load on the network. PDLG software in place on the network is monitored and/or tested. Multiple similarly configured terminals may be provided for a large number of 1x-EVDO calls, e.g., 40-50, in a laboratory setting.

Abstract: A method and a control unit for controlling a power level being drawn from a power source (26). Based on a determined rate of change of a measured voltage (1) an estimated remaining runtime is calculated. The estimated remaining runtime represents a time where specific run criteria will no longer be fulfilled if the present power level is maintained. The estimated remaining runtime is compared to a threshold value, and in case the estimated remaining runtime is shorter than the threshold value, the power drawn from the power source (26) is decreased. Thereby the runtime for the power source (26) is maximised. This is particularly useful if the power source is a limited power source, such as a battery (26), e.g. for running a compressor (27) for a movable refrigeration system (24). The invention is suitable for automotive applications.

Abstract: A flexible tank has a volume-variable chamber formed so as to be sectioned by a flexible tube that is expanded or contracted in accordance with the amount of the contained chemical liquid, and adaptor parts attached to the flexible tube. A primary-side port open to the volume-variable chamber is open into one of the adaptor parts, and a secondary-side port open to the volume-variable chamber is open into the other adaptor part. The contact between the chemical liquid and air in the volume-variable chamber is suppressed to minimum level, thereby containing the chemical liquid without deteriorating the cleanliness of the chemical liquid, and improving discharge accuracy of the chemical liquid.

Abstract: A method and a control unit (4) for controlling a supply of power to an electrical circuit comprising a switch (3). An output voltage of a first power source (5), which is connected to the circuit, is measured and compared to a predefined threshold voltage. If the measured voltage is smaller than the threshold value it is determined that the switch (3) is in a closed state, and if the voltage is larger than the threshold value it is determined that the switch (3) is in an open state. The supply of power is controlled in accordance with the open/closed state of the switch (3). Preferably, the electrical circuit is connected to a second power source (9) when the switch (3) is in a closed state. Power is conserved while it is ensured that sufficient power is available when needed. The invention is very suitable for supplying power to a lamp (1) positioned inside a refrigeration compartment (2), especially when the system is battery powered.

Abstract: In a floor control system for a network, a floor control server controls a floor-based application for communications between multiple participant terminals. The server carries out a floor determination process that includes an adaptive waiting function. Upon receiving an initial floor request message, the server waits for additional requests before determining the floor winner. The wait time is a function of the floor request load. When the system is lightly loaded, the wait time is generally small. For heavier request loads, the wait time is generally longer, to ensure that a reasonable number of requests are received before awarding the floor. The wait time may be limited by a maximum wait time, which is a function of the floor request load. If a designated number of floor requests is received before the maximum wait time expires, a temporary floor winner is granted the floor if its priority is sufficiently high.

Abstract: A symmetrical vertical Hall element comprises a well of a first conductivity type that is embedded in a substrate of a second conductivity type and which is contacted by four contacts serving as current and voltage contacts. From the electrical point of view, such a Hall element with four contacts can be regarded as a resistance bridge formed by four resistors R1 to R4 of the Hall element. From the electrical point of view, the Hall element is then regarded as ideal when the four resistors R1 to R4 have the same value. The invention suggests a series of measures in order to electrically balance the resistance bridge. A first measure exists in providing at least one additional resistor. A second measure exists in locally increasing or reducing the electrical conductivity of the well. A third measure exists in providing two Hall elements that are electrically connected in parallel in such a way that their Hall voltages are equidirectional and their offset voltages are largely compensated.

Abstract: A chemical liquid supplying apparatus can discharge chemical liquid with high accuracy and monitor a leakage of an incompressible medium from a region between a piston and a cylinder. A pump has a flexible tube for partitioning a pump chamber and a drive chamber, and the incompressible medium is supplied to the drive chamber by the piston reciprocating in a cylinder hole of the cylinder. A bellows cover is provided between the piston and the cylinder, and forms a seal chamber contiguous to a sliding face of the piston. A seal-chamber pressure sensor is attached to the cylinder so as to detect the pressure of the incompressible medium for sealing enclosed in the seal chamber, and a deterioration degree of a seal member is determined by detecting the pressure in the seal chamber.
