Abstract: A tubular medical fluid flow set comprises a pressure sensing chamber connected in flow-through relation to fluid flow tubing of the set. The pressure sensing chamber defines a movable, flexible, impermeable diaphragm dividing the chamber into two separate compartments. The fluid flow tubing communicates with one of the compartments and is isolated from the other of the compartments. A port is carried on the chamber, the port having a seal therein, and communicating with the other of the compartments. Thus, the other of the compartments is hermetically sealed until the port is opened for connection with a pressure measuring device, to keep the flexible diaphragm in a desired, initial position prior to opening of the seal.

Abstract: Methods and systems are provided for adjusting a compressor recirculation valve in response to condensate forming conditions in a charge air cooler (CAC). In one example, a compressor recirculation valve may be opened in response to an induction pressure greater than a threshold pressure when the induction pressure is greater than required to produce a manifold pressure required for a torque demand. Further, a wastegate may be opened to further reduce the induction pressure during certain driving conditions.

Abstract: This disclosure is directed to regulating electric power at a node of a system for distribution of electricity. A voltage controller can identify properties of branch structures in a system that includes a voltage regulation device that controls a voltage source supplying electricity to nodes via the branch structures. The voltage controller can receive information on voltage and current associated with electricity provided by the voltage source. The voltage controller can receive, from a metering devices at nodes in the system, primary voltage information. The voltage controller can select one of the nodes based on the primary voltage information. The voltage controller can determine, based on the properties, an impedance for a branch structure corresponding to the selected node. The voltage controller can control the voltage regulation device based on the impedance for the branch structure corresponding to the selected node and the information on the voltage and the current.

The set of available functions comprises a record function operative to cause the digital video recorder to record content and store that content on the digital video recorder, and a playback function operative to cause the digital video recorder to play back content stored on the digital video recorder. Subsequently, at least in part in response to the instructions from the user, the DVR controller issues a command to the digital video recorder to perform the function. The digital video recorder is operative to present content on a presentation device controlled by the user. The DVR controller, in turn, is remotely disposed from the digital video recorder in a facility of a content provider.

Abstract: An accelerated vapor recompression apparatus 10 converts incoming flow 35a to a concentrate 35c by developing a concentration profile 146 within a tank 30 holding a liquid 23 containing dissolved solids. The resulting curve 160 of saturation temperature of the stratified liquid 23 (such as a brine 23 or other material 23) moves away from the curve 162 corresponding to fully mixed conditions. The shift 174, 180 in saturation temperature results in increased boiling without increased energy from a heater 70 or compressor 50.

Abstract: A thermostat is described that includes a rechargeable battery, a graphical user interface and a wireless network communication capabilities. During installation, in cases where the rechargeable battery is below a first threshold, the installation procedure is limited so as to avoid energy intensive installation steps which may not be supported by the low battery level. An example of an installation step that is avoided due to low battery level is set up of wireless communication. According to some embodiments, if the battery level is very low during initial installation, the installation process is halted while the battery is charged. An indication such as a flashing LED may be displayed so as to indicate to the user that the battery is being charged.
