摘要:
An integrated circuit that performs data demodulation on partially despread symbols includes a despreading unit, a channel compensation unit, and a symbol combiner. The despreading unit despreads input samples and provides despread symbols for a first code channel with a first spreading factor. The channel compensation unit multiplies the despread symbols with channel estimates and provides demodulated symbols. The symbol combiner combines groups of demodulated symbols to obtain recovered data symbols for a second code channel with a second spreading factor that is an integer multiple of the first spreading factor. The channel compensation and symbol combining are dependent on whether or not transmit diversity is used. For a TDM design, despread symbols for multiple first code channels are processed in a TDM manner, one channel at a time, to obtain recovered data symbols for multiple second code channels. The channel compensation unit and symbol combiner can be operated in a pipelined manner.

The process of bonding a first workpiece to a second workpiece is disclosed comprising the steps of fabricating a sintered bonding pad formed from a matrix of randomly oriented metallic fibers. The bonding pad is interposed between the first and the second workpiece and the first and second workpieces are biased into engagement with the bonding pad. Heat is applied to the first workpiece to the second workpiece for transforming substantially all of the metallic fibers into a liquid for bonding the first workpiece to the second workpiece.

Systems and methods for monitoring a plumbing system. A sensor module includes an acoustic flow sensor, and is configured to be attached to a water pipe. In response to receiving sound at the acoustic flow sensor above a threshold level, the sensor module wakes up from a low-power sleep mode and begins collecting acoustic data. The acoustic data is analyzed to determine if water is flowing through the pipe, and if so, a thermal flow sensor may also be activated. Flow data is collected while the water is flowing to document the flow event. In response to the sensor module determining the flow of water has stopped, the collected data is transmitted to a remote server, and the sensor module returns to sleep mode. Multiple sensor modules can be deployed to form a sensor network that communicates wirelessly to monitor the plumbing system.

摘要:
A composite hollow ceramic fiber includes a porous hollow core supporting a thin, dense sheath. The non-gas-tight core comprises a first ceramic material and an interconnecting network of pores. The gas-tight sheath comprises a second ceramic material. The fiber is made by extruding a core suspension of particles of the first ceramic material, a polymeric binder, and a solvent and a sheath suspension of particles of the second ceramic material, a polymeric binder and a solvent, respectively, from a spinnerette and coagulating the nascent hollow fiber to effect phase inversion of the polymeric binders. The resultant green fiber is sintered in a two step process. First, the binders are burned off. Second, the sheath is densified and the second ceramic material is sintered without fully sintering the first ceramic material. The first ceramic material of the core suspension has a median particle size greater than that of the second ceramic material of the sheath suspension.
