Abstract: Examples provide an apparatus having a first accumulator that water received from a first supply line. A first conduit connects to the first accumulator and provides a second supply line from the first accumulator to a fixture. The second accumulator receives drainage water from the fixture. The second conduit connects to the second accumulator and includes a drainage line that directs the drainage water away from the second accumulator. A pump associated with the second accumulator assists with moving the drainage water out of the second accumulator through the drainage line.

Abstract: Examples provide a configurable, modular manifold system for distributing water. The manifold receives water via a first supply line dropped vertically down from a ceiling structure. The first supply line is connected to a water source, such as a water tank or pre-existing water line without demolition. The water may be heated or filtered and then supplied to a fixture or other device via a perpendicular second supply line. Drainage from the fixture is received via a drainage line. The drainage accumulates in an accumulator tank. The drainage water is pumped out via a second vertical drainage line carrying the drainage water away. The second line eventually connects to a pre-existing sewage line or septic system for treatment. The manifold may be moved or relocated easily to provide water to fixtures or other devices modularly without alteration of fixtures or access demolition to existing structures.

Abstract: A vehicle cabin simulator module provides flexible reconfiguration of transducer locations for evaluating acoustic performance in a vehicle design at a prototyping stage. A frame lattice defines a plurality of cavities around an interior space. A plurality of transducer assemblies are mounted in selected ones of the cavities, each assembly having a faceplate mounting a transducer for acoustic coupling with the interior space. Blank panels are mounted in other selected cavities to shutter the respective cavities. A covering liner is applied to an inner side of the frame lattice. Wiring is provided to interconnect the transducers with a signal processor. The frame lattice further defines a door section radially movable for enclosing the interior space at a closed position and for providing ingress and egress to the interior space at an open position.

Abstract: A computer, including a processor and a memory, the memory including instructions to be executed by the processor to determine a first root-mean-square signal level of an audio data stream with a first delay, apply a bass shelf filter to the audio data stream based on the first root-mean-square signal level and an audio volume level, determine a second root-mean-square signal level of an audio data stream with a second delay and apply a treble shelf filter to the audio data stream based on the second root-mean-square signal level and the audio volume level. The instructions include further instructions to output the audio data stream to an audio amplifier and one or more speakers.

Abstract: An electric submersible pump (ESP) intake system, apparatus and method is described. An ESP intake system includes a filtered intake section coupled adjacently to a sliding sleeve intake section, wherein the sliding sleeve intake section has a closed initial state and is selectively actuatable to an open position when the filtered intake section becomes at least partially clogged. An ESP intake method includes operating an ESP pump downhole in a well including abrasive-laden fluid, the ESP pump including a filtered intake section and an actuatable intake section, employing the filtered intake section as a first fluid entrance into the ESP pump, monitoring information from ESP sensors during employment of the first fluid entrance to identify clogging of the filtered intake section, and opening the actuatable intake section upon the clogging so identified such that the actuatable intake section serves as a second fluid entrance into the ESP pump.

Abstract: An audio processor generates a vocal-free audio signal from an audio signal received from an audio source, directs a cross-fader to fade from the audio signal to the vocal-free audio signal responsive to occurrence of a trigger condition indicated by a status signal, and directs the cross-fader to fade from the vocal-free audio signal to the audio signal responsive to the trigger condition no longer being present.

Abstract: Method and apparatus are disclosed for responding to HVAC-induced vehicle microphone buffeting. An example disclosed vehicle includes a microphone, a speaker, and a buffeting detector. The example microphone is electrically coupled to an input of a voice-activated system. The example speaker is located on a front driver side of the vehicle. The example buffeting detector, when a button is activated, determines a buffeting factor of a signal captured by the microphone. Additionally, the example buffeting detector, in response to the buffeting factor satisfying a threshold, activates a relay to electrically couple the speaker to the input of the voice-activated system.

Abstract: A vehicle includes a plurality of sensors including exterior sensors. Vehicle signals, such as those derived from sensors, are processed to detect alertable conditions and each alertable condition is represented by a created software object. A location is associated with each software object, such as corresponding to a location of an exterior feature that gave rise to the alertable condition. The software object is updated over time according to the vehicle signals, such as by updating the location according to movement of the obstacle. The software objects are processed to drive an array of speakers effective to simulate a sound originating from the location associated with the software object. The sound generated by the speakers may be repeated chimes having a volume and period determined according to the location.
