Abstract: A bipole power transmission network includes a first upstream power converter which has a first DC terminal that is connected with a first transmission conduit which extends, in-use, to a first downstream power converter. The first upstream power converter has a second DC terminal that is connected with a return conduit which extends, in-use, to the first downstream power converter and a second downstream power converter. The first upstream power converter has at least one first AC terminal electrically connected with a first AC power source. The bipole power transmission network includes a second upstream power converter which has a third DC terminal that is connected with the return conduit, and a fourth DC terminal which is connected with a second transmission conduit that extends, in-use, to the second downstream power converter, and at least one second AC terminal electrically connected with a second AC power source.

Abstract: An air handler unit for use with residential heating, ventilation, and air conditioning (HVAC) systems. The air handler unit has high resistance mediums (HRMs) coupled closely to a wide-angle vane-diffuser mixed-flow fan system. The HRMs are placed immediately upstream and downstream of the wide-angle vane-diffuser mixed-flow fan to form a closely coupled, compact air handler that provides significant efficiency and noise benefits.

Abstract: Systems and methods are provided herein for facilitating the scheduling and controlling the presentation of media content at one or more Venues (e.g., bars, restaurants). The scheduling and presentation is coordinated by a distributed system including a scheduling management server and a local subsystem at the Venue. The system is also configured to receive information from remote devices including electronic media guides as well as user devices enabling venue managers or the public to interact with the system. The system is configured to maintain a content presentation schedule and coordinate presentation at a Venue based on parameters obtained from remote devices including: the requirements of the Venue, requests from Patrons, programming available for presentation and the availability of resources at the venue (e.g., televisions).

Abstract: An antenna system and method is provided for communicating with a medical device implanted in a patient. Upper and lower shells join to form an antenna tunnel there between. At least one of the upper or lower shells includes an opening along an edge thereof to form a passage to the antenna tunnel. The upper shell includes an outer patient engaging surface configured to abut against the patient. An antenna assembly includes a substrate and an inductive RF antenna provided on the substrate. The antenna assembly is movable within the antenna tunnel. The substrate includes a stem projecting through the passage. A handle is joined to the stem and is located outside of the antenna tunnel. The antenna assembly is movable within the antenna tunnel in response to adjustment of the handle relative to the upper and lower shells. An electronics circuit is electrically coupled to the antenna and is configured to transmit and receive inductive RF signals to and from the medical device implanted in a patient.

Abstract: Provided is a check valve assembly including a check valve having a body and a stem having at least one radially inwardly deflectable member having an end with a radially outwardly projecting catch, and a valve shield retained on the stem between the body and the end of the at least one radially inwardly deflectable member by the radially outwardly projecting catch. In this way, a mechanical bond is provided between the check valve and the valve shield, thereby eliminating the need to clean the body of the check valve to remove contaminants to allow an adhesive to hold the check valve to the valve shield.

Abstract: The present invention provides a technique using current sensing to control the pressure at constant level without the direct sensing of the pressure. This technique will help to reduce dependency solely on switch or sensor and their non linearity and other associated problems such as the non-repetitive behavior, being affected by EMI etc. The technique includes using a pump controller featuring one or more modules configured to respond to one or more input signals containing information about current provided from a pump; and configured to provide one or more output signals containing information to control the pump to operate at a substantially constant pressure without the direct sensing of pump pressure. The one or more modules control the operation of the pump based at least partly on a table of characteristics related to voltage and current that is calibrated for each pump.

Abstract: A disk drive is disclosed comprising a disk, a head actuated over the disk, a host interface for receiving disk access commands from a host, a command queue for queuing the disk access commands, and a stream detection engine for evaluating the disk access commands to detect a plurality of streams accessed by the host. The stream detection engine maintains a stream data structure for each detected stream, wherein the stream data structure comprises a frequency counter for tracking a number of disk access commands associated with the stream out of a predetermined number of consecutive disk access commands received from the host. A disk controller selects one of the streams for servicing in response to the frequency counters.

Abstract: A turret mooring system for a vessel which includes a moon pool comprises a turret which is positioned in the moon pool, a buoy and anchor chain assembly for anchoring the turret to the sea floor, a bearing assembly for rotatably connecting the turret to the vessel, and a bearing support assembly which comprises an upper ring member to which the bearing assembly is connected, a lower ring member which is connected to the vessel in the moon pool, and a number of elongated support beams which are connected between the upper and lower ring members. In addition, the lower ring member is connected to the vessel near the vertical center of the vessel in order to minimize the deflections of the bearing assembly due to hogging and sagging of the vessel.
