Abstract:
A multi-channel fiber optic rotary joint (FORJ) includes an external housing, a stationary collimator array, a rotating collimator array, an all-reflective de-rotating prism and a gear ratio. The external housing contains an internal cavity having a longitudinal rotation axis. The stationary collimator array is affixed to the external housing approximate a first end of the internal cavity. The rotating collimator array is rotatably attached to the external housing approximate a second end of the cavity. The second end of the cavity is opposite the first end of the cavity. The rotating collimator array is configured to rotate about the rotation axis. The de-rotating prism is located along the rotation axis within the internal cavity between the stationary collimator array and the rotating collimator array. The prism is retained in a prism housing, which is rotatably attached to the external housing and the prism housing is configured to rotate about the rotation axis.
Abstract:
A virtual computing services deployment network provides a consistent user experience from a variety of locations via a connection fabric for accessing a virtual desktop. The connection fabric identifies a user profile defining the virtualized desktop resources required for a particular user. The connection fabric includes distributed data and processing in nodes distributed throughout a public access network accessible from a user access device. Each of the fabric nodes is operable to provide an identifier (such as an IP address) of a computing resource adapted to provide the user specific desktop. A user access device accesses a local fabric node in the connection fabric, and the fabric node determines a computing resource matching a user profile of expected computing resources. The fabric node associates the user access device with the computing resource and sends the user access device an identifier for directly accessing the computing resource. The determined computing resource may be determined by a centralized virtual computing approach, thus providing appropriate scaling without significantly impacting the existing fabric.
Abstract:
A heat exchanger evaluation system (84) includes a refrigeration subsystem (126) and a platform (94) in communication with the subsystem (126) for attachment of a heat exchanger (32). The system, (84) further includes a thermal imaging camera (168) and a monitor (100). A method (180) entails routing a fluid (38) through the heat exchanger (32) via the refrigeration subsystem (126). The camera (168) detects the temperature variation across the heat exchanger (32) as the fluid (38) flows through the heat exchanger, and provides successive thermal images representing the temperature variation responsive to the flow of the fluid (38). The thermal images are utilized to determine an efficacy of the flow through the heat exchanger (32). In particular, a determination can be made as to whether the flow deviates from a pre-determined flow path (79) of the fluid (38) through the heat exchanger.
Abstract:
A receiver (24) for a condenser system (20) includes a body (32) in fluid communication with a header (28) of the condenser system (20). A first cap (38) is coupled to an end (34) of the body (32) and has a saddle portion (40) coupled to the header (28). The receiver (24) further includes a tube section (42) coupled to a second end (36) of the body. A second cap (50) is removably interconnected with the tube section (42) following insertion of a service cartridge (76) into the body (32). The service cartridge (76) includes a substantially-rigid tubular member (78) having rib members (84) radially extending from an outer surface (86) of the tubular member (78). Covers (90, 92), each having openings (94, 96), are coupled to opposing ends of the tubular member (78). The service cartridge (76) includes multiple features for drying, filtering, and/or leak detection.
Abstract:
An apparatus is disclosed that comprises a sensor to detect a medical condition; a processor to evaluate the signals from the sensor; an input device and read/write medium to record cues that correspond to the various condition(s) detected by the sensor; and an audio output device to play prerecorded audio cues when a particular medical condition is detected. The audio cue provides a unique reminder message to encourage a person to take a certain action that is healthy.
Abstract:
A process is disclosed to visually capture a person doing a set of steps for an exercise, and then to compare that person during exercise to those steps, measuring the results. Each exercise is tailored to the individual patient, rather than to an “ideal” or “generic” standard. This flexibility allows a physical therapist to optimize treatment for patients progressively, and/or to accommodate multiple physical problems in one patient. This invention can be used as a medical software product under the guidance of a physical therapist for rehabilitation exercises. It may alternatively be used as a fitness or sports training device under the guidance of a trainer or coach. By providing visual data and tracking results, it enhances communication between the physical therapist and the patient (or trainer and athlete), and optionally, the physician.

Abstract:
A service provider network supports multiple tenants by having a virtual local area network for each enterprise, and a router connected to enterprise networks of the multiple tenants including a virtual router for each enterprise. The virtual router has a distinct routing table for each enterprise, for routing traffic between the desktops hosted on the plurality of host machines and the computer resources on the enterprise networks.

Abstract:
A remote access manager in a virtual computing services environment negotiates a time limited NAT routing rule to establish a connection between a remote device and virtual desktop resource providing user computing services. A series of NAT connection rules are revised in a dynamic manner such that a pool of ports is available to connect a plurality of remote users to local virtual compute resources over one or more public IP addresses. Once a connection is established, an entry is made in a firewall state table such that the firewall state table allows uninterrupted use of the established connection. After an entry has been made in the state table, or the routing rule has timed out, the port associated with the original NAT routing rule is removed and the same port can be re-used to establish another connection without disrupting active connections.
