Abstract: A hydrant comprising a housing forming a reservoir; and a piston configured to force residual fluid out of the reservoir to an outlet and to allow supply fluid to flow from an inlet through the piston to the outlet when the piston is actuated in the housing to a first position, and when the piston is actuated in the housing to a second position, to restrict flow of the supply fluid to the outlet and to allow at least a portion of the supply fluid that has flowed from the inlet to flow into the reservoir thereby becoming new residual fluid.

Abstract: A radar system determines the range and velocity of a target, such as an atmospheric structure. The radar system transfers a first series of pulses and a second series of pulses. The first series of pulses and the second series of pulses have orthogonal polarizations. The first series of pulses and the second series of pulses have a same pulse repetition time. The first series of pulses and the second series of pulses are offset by a time amount. The target reflects energy from the first series of pulses to generate a first series of echoes and reflects energy from the second series of pulses to generate a second series of echoes. The radar system processes the first series of echoes and the second series of echoes to determine the range and velocity of the target.

Abstract: A vacuum cleaner air/liquid separator is provided according to the invention. The separator includes an offset air/liquid airflow inlet for receiving an air/liquid airflow, with the offset air/liquid airflow inlet possessing a width and a height. The separator further includes a substantially cylindrical separator chamber communicating with the offset air/liquid airflow inlet, wherein the offset air/liquid airflow inlet is radially offset from the separator chamber. The separator further includes a lead-in track extending from the offset air/liquid airflow inlet and at least partially around the circumference of the separator chamber. The lead-in track tapers from substantially the width of the offset air/liquid airflow inlet into the separator chamber. The air/liquid airflow is entrained into a downward spiraling path in the separator chamber by the lead-in track.

Abstract: An integrated circuit processes communication packets and comprises a pointer cache and control logic. The pointer cache store pointers that correspond to external buffers that are external to the integrated circuit and configured to store the communication packets. The control logic allocates the external buffers as the corresponding pointers are read from the pointer cache and de-allocates the external buffers as the corresponding pointers are written back to the pointer cache.

Abstract: An improved bag docking assembly for aligning a vacuum bag for engagement with a dirty air outlet nozzle on a vacuum cleaner, and for retaining the vacuum bag in the position of engagement. The assembly incorporates an anchor member and a mounting member. The anchor member serves to attach the bag docking assembly to the vacuum cleaner. The anchor member can be a substantially flat piece of plastic having a central opening for closely receiving the dirty air outlet nozzle on the vacuum cleaner. The central opening can have a shoulder for engaging a rim or similar protrusion formed about the perimeter of the dirty air outlet nozzle. Additionally, protrusions are located on the anchor member that align with voids in the vacuum bag collar to ensure that correct alignment of the vacuum bag has been achieved.

Abstract: Communication circuitry is comprised of processing circuitry, parallel channels, and crossbar integrated circuits. The processing circuitry exchanges the communications between communication links and the parallel channels. The parallel channels transfer the communications in parallel with a clock signal. The crossbar integrated circuits receive the communications and the clock signal over the parallel channels, switch the communications based on the clock signal, and transfer the switched communications to the parallel channels.

Abstract: A flow meter is disclosed that is comprised of a base, a driver, pick-offs, and a flow tube made from a fluoropolymer substance. The base of the flow meter is comprised of a first leg and a second leg. The first leg includes a tube opening and an adhesive opening and the second leg includes a tube opening and an adhesive opening. The flow tube passes through the tube openings of the first leg and the second leg. The tube opening of the first leg has a diameter slightly larger than the flow tube to create a gap between the tube opening and the flow tube. The adhesive opening of the first leg provides access to the gap so that adhesive may be applied to the flow tube and an inner surface of the tube opening to affix the flow tube to the base. The adhesive opening in the second leg performs the same function.

Abstract: A process analysis system includes sensors and a processing system. The sensors monitor the process to generate sensor signals. The processing system processes the sensor signals to detect a deviation from a baseline for the process. The processing system generates a process vector for the deviation in response to detecting the deviation. The processing system compares the process vector to a plurality of library vectors to classify the deviation. In some examples, the process comprises a system that supplies water.

Abstract: A sensor system includes an enclosure mounted externally on an aerial vehicle and a sensor chamber mounted internally within the aerial vehicle. The enclosure receives and converges air particles to cause inertial separation that transfers a first portion of the air particles to a first air transfer path and that causes a second portion of the air particles to bypass the first air transfer path. The first air transfer path transfers the first portion of the air particles from the enclosure to the sensor chamber. The sensor chamber includes at least one sensor that produces sensor data for the first portion of the air particles. A second air transfer path transfers the first portion of the air particles from the sampling chamber to the enclosure. The enclosure transfers the first portion of the air particles and the second portion of the air particles to the atmosphere.
