Abstract: A system includes a pressure exchanger (PX) configured to receive a first fluid via a first inlet and a second fluid via a second inlet. The PX is to exchange pressure between the first fluid and the second fluid and provide the first fluid at a first outlet and the second fluid at a second outlet. The system further includes a first sensor to provide first sensor data associated with the first fluid prior to the first fluid entering the first inlet and a second sensor to provide second sensor data associated with the second fluid prior to the second fluid entering the second inlet. The system further includes a controller to receive user input and cause a first adjustment of the flowrate of the first fluid into the first inlet and cause a second adjustment of the flowrate of the second fluid into the second inlet.

Abstract: A system includes an isobaric pressure exchanger (IPX) configured to exchange pressure between a first fluid and a second fluid. The IPX includes a rotor configured to rotate about a longitudinal axis of the rotor. The rotor forms rotor ports arranged substantially symmetrically around the longitudinal axis at a distal end of the rotor. The IPX further includes an end cover configured to be disposed at the first distal end of the rotor. The end cover forms end cover ports. The rotor ports are arranged for hydraulic communication with the end cover ports. The IPX further includes an insert disposed between two of the rotor ports or between two of the end cover ports.

Abstract: Systems, methods, and computer-readable media are described for compact radar systems. In some examples, a compact radar system can include a first set of transmit antennas, a second set of receive antennas, one or more processors, and at least one computer-readable storage medium storing computer-executable instructions which, when executed by the one or more processors, cause the radar system to coordinate digital beam steering of the first set of transmit antennas and the second set of receive antennas, and coordinate digital beam forming with one or more of the second set of receive antennas to detect one or more objects within a distance of the radar system.

Abstract: A wearable haptic navigation system for obscured visibility environments, the wearable haptic navigation system including: a wearable haptic component, in one alternative a body covering suite; and a mapping data collector and processor in communication with the wearable haptic component; wherein the mapping data collector and processor collects data related to a path traversed by a user of the wearable haptic navigation system and generates at least one proprioception suggestion signal to the wearable haptic component providing the user with a suggested safe egress path and/or a suggested safe body position.

Abstract: A deployable electrical contact device is provided that includes a body portion and a mounting arrangement. The mounting arrangement is controllably deployable from the body portion. The mounting arrangement is configured to retain the device at a position at a metallic well structure by mechanically engaging with a wall surface of the metallic well structure. The mounting arrangement includes electrically conductive pads configured to provide electrical continuity between the engaged metallic well structure and the mounting arrangement. The device is configured such that when deployed an electrical signal path between one or more of the conductive pads and the body portion is established to provide electrical continuity between the metallic well structure and the body portion.

Abstract: A handheld controller configured to be held by a user's hand. The handheld controller comprising a main body, and a handle extending from the main body, wherein the handle has a palm side and a finger side. A control button is positioned on the main body or handle, and a detection sensor is on the handle. The detection sensor is positioned to detect the presence of the finger or palm of a user's hand engaging the handle. The detection sensor can be a capacitive touch sensor, a proximity sensor or other detection sensor operative to detect the touch or spatial presence of the user's hand or fingers.

Abstract: A carrier for a plurality of containers includes an upper web having a plurality of upper web apertures, each for receiving a chime and a neck of one of the containers therethrough. Each upper web aperture has a plurality of tabs formed at an inside edge thereof. Each tab is configured for bending upward when contacting the chime of one of the containers. A lower web has a plurality of lower web apertures, each for receiving a body of one of the containers therethrough. A side web connects the upper web with the lower web, and may be formed together with the upper web and the lower web as a single piece, or into two separate portions that may be adhered or otherwise fastened together.

Abstract: A fluid handling system includes a pressure exchanger (PX) configured to receive a first fluid at a first pressure and a second fluid at a second pressure and exchange pressure between the first fluid and the second fluid. The system further includes a condenser configured to provide corresponding thermal energy from the first fluid to a corresponding environment. The system further includes a receiver to receive the first fluid output by the PX. The receiver forms a chamber to separate the first fluid into a first gas and a first liquid. The system further includes a first booster to increase pressure of a portion of the first gas to form the second fluid at the second pressure and provide the second fluid at the second pressure to the PX.

Abstract: A system for packaging two or more containers with a paperboard carrier having two or more apertures. Each aperture has a plurality of tabs formed at an inside edge thereof that bend upward when contacting a lower edge of a chime of one of the containers. The system includes a platen having apertures for pressing the carrier down uniformly onto the containers and carrier supports configured for maintaining the carrier in a flat configuration as the platen presses the carrier onto the containers substantially simultaneously. Some embodiments of the system include a manual applicator, while other embodiments include a semi-automatic apparatus that utilize linear actuators to facilitate loading the carriers and applying the carriers to a group of containers. Methods of use are also disclosed.

Abstract: The present disclosure provides a device for collecting a biological sample. The device may include a tube, a primary cap which engages an open end of the tube, and a secondary cap which engages the primary cap. The device may include a collection member, which may include a swab. Methods of collecting and analyzing samples are also disclosed.

Abstract: The present invention relates to a method for the production of a carbon nanotube structure which has substantially aligned carbon nanotubes (CNTs) and to a temperature-controlled flow-through reactor.

Abstract: An electric motor having low vibration and/or noise comprises a rotor or stator comprising permanent magnets each comprising at least two pole pairs, with an internal flux gap within the permanent magnets between adjacent internal pole pairs. The internal flux gap between the internal pole pairs may be similar to an external pole to pole physical spacing between adjacent poles of adjacent magnets. The motor is suitable for use in for example a laundry washing machine or dryer or washer-dryer.
