The present invention includes a plurality of input/output processors communicating with a master processor. Each of the input/output processors has a filtering mechanism to filter the inputs before transmission to the master over the communication channel precluding the necessity of filtering at the master. More importantly, the shared communications system is not loaded down with every change of an input. Because of this feature, only meaningful changes are put on the communication line, thus ...

A drive installation including two driving engines and a transmission having an input and an output shaft. The first driving engine is connected to the input shaft by way of an engageable clutch; such as a one-way clutch or a clam clutch. The second driving engine is connected to both the input shaft of the transmission by way of a first engageable coupling and to the output shaft of the transmission by way of a second engageable coupling. The transmission is operable to selectively connect eith...

An amplifier system includes an operational amplifier having a reference applied to one input terminal. A voltage above or below the reference voltage is applied to the other input terminal by way of an interface circuit. The interface circuit adapts the input for use with a switch or, alternatively, the interface may be disabled to permit use of a variable resistor input such as a thermistor. The output of the operational amplifier may be a switching circuit. The amplifier system is adapted for...

A technique for providing external mode select information to a chip capable of operating in different modes without adding pin overhead. One of the normal signal pins of the chip is used as an input pin for a brief period of time at power-on before the chip becomes fully operational. During this time, a mode select signal from outside is communicated onto the pin and latched into the chip, where it remains during subsequent normal operation of the chip.

An apparatus for and method of processing a service request in XML document format via a legacy data base management system to produce a response. The service is defined by a component definition which is presented to the legacy data base management system as a combination of tables, variables, and script defining various components. The inputs are defined in accordance with a combination of components from a variety of sources. The legacy data base management system honors the service and retur...

A low noise amplifier (500) is provided for amplifying signals in a frequency band. The low noise amplifier (500) comprises several amplifying elements (505, 506) that share a load impedance (503) and a degeneration impedance (504). One of the amplifying elements (505, 506) is activated at a time that the rest are deactivated. The activation and deactivation is done by feeding a bias to a bias port (501, 507) or grounding the same, respectively. A signal to be amplified is fed to the correspondi...

For use in a digital signal processing system, a filter implementation factors in the time difference between consecutive searches for the same signal and modifies the filter depending on the time-arrival differences of consecutive search results. An example application to which the invention is particularly well adapted is in a mobile receiver for a cellular radiotelephone communications system. In accordance with the present invention, after determining a relative arrival time of data sample s...

Microfluidic devices having a plurality of functional features for performing one or more fluidic operations in parallel are provided. Reagents, samples or other fluids common to multiple functional features ("common fluids") may be input into a microfluidic device or system through one or more distributing inputs that divide and distribute the common fluids as desired. The use of a multi-layer fabrication technique allows multiple distributing inputs to distribute to multiple functional feature...
