  • Publication number: 20230414395
    Abstract: An energy storing brace to be worn on a limb of a user may include a primary frame and a secondary frame pivotally connected to the primary frame. An energy storage assembly may include a spring member that is spaced apart from the first hinge and the second hinge. A first energized cord path may extend from the first hinge to the energy storage assembly. A tensioning cord may extend from a first anchor section secured relative to the first primary arm, across a first peripheral surface and through the first energized cord path to the spring member. Pivoting the brace from an extended position toward a flexed position may cause (i) the first extension member to exert a tension force on the first cord segment thereby loading the spring member and the spring member applies a restorative spring force to urge the brace to return to the extended position.

  • Patent number: 11747385
    Abstract: A device for detecting stray electrical currents in fluid mediums comprises at least two probes for partially disposing in a fluid medium and a control unit. The control unit comprises at least one analog-to-digital signal converter in electrical communication with at least one of the probes, at least one audio-visual alarm, and a processor operably coupled to the at least one converter and to the at least one audio-visual alarm. The processor is operable to measure an electrical potential difference between the two probes, to calculate at least one frequency-dependent characteristic associated with a plurality of said measurements, and to transmit an alert signal if the at least one frequency-dependent characteristic satisfied a threshold. Advantageously, by monitoring for the frequency, the device more consistently and more reliably detects the presence of stray alternating currents.

  • Patent number: 9457247
    Abstract: A tubular bat is provided whereby at least one diaphragm is located within the internal cavity of the bat. The diaphragm is fastened at its peripheral edge to the inner surface of the bat wall, thereby dividing the internal cavity into two separated cavities, thus creating two sweet spots, or shifting the existing sweet spot forward towards the distal end of the bat. This improves player performance by providing an expanded number of optimal hitting zones or by moving the optimal hitting zone farther from the bat handle.

  • Patent number: 8116638
    Abstract: A signal receiver, such as an RF-matched filter receiver, includes an optical source (e.g. a mode-locked laser) providing an optical signal, and a first optical modulator to modulate the optical signal with a received RF signal and provide a modulated optical signal. A second optical modulator modulates the modulated optical signal with a reference signal and provides a twice modulated optical signal. The modulators may be Mach-Zehnder Modulators (MZM) and/or Indium Phosphide (InP) modulators. An optical detector receives the twice modulated optical signal and provides a detected signal, and a processing unit receives the detected signal and extracts or measures cross-correlation between the received RF signal and the reference signal.

  • Patent number: 7274684
    Abstract: In a complete network-in-a-box system acting as an enterprise network demarcation point, packets such as voice, video and data packets, are routed over common network connections, such as LAN and WAN. The packets are mapped from a public address field (such as an IP address) and port number to a private address field and port number, the mapping process typically being handled by a NAT (Network Address Translation). The packets are also prioritized, by marking the packets for priority queuing and routing, and configuring the bandwidths of the WAN traffic and the voice traffic to predetermined quantities and configuring the address fields of the voice devices. Simultaneous transmission of the various packets can be limited to predetermined quantities, typically by utilizing a CAC (Client Access Control).

  • Publication number: 20030033418
    Abstract: The invention provides methods and systems using a Media Gateway Control Protocol (MGCP) Application Layer Gateway (ALG) for delivery of VoIP packets to Internet Protocol (IP) phones and to client adapters (CA). The invention provides a customer premises device acting as a proxy between a single Wide Area Network (WAN) Extranet IP address and any number of MGCP client adapters and MGCP phones. To act as a proxy, the MALG parses MGCP signaling packets and opens communications ports as required to deliver VoIP. The MGCP ALG (MALG) registers MGCP phones and identifies required service parameters. The MALG represents all registered MGCP phones to the Extranet via its single public WAN IP address. The MALG is integrated into premises networks via flexible multi-port LAN connections. The MALG can connect to existing premises networks via multiple configuration options. These options are part of the unique MALG capabilities.

  • Patent number: 6061902
    Abstract: The method of the present invention fabricates a plurality of composite structures so as to permit the reliable recovery of leads embedded within respective ones of the composite or smart structures. In this regard, the method of the present invention permits a plurality of composite structures to be fabricated, such as by means of a continuous pultrusion process, while enabling the leads to be recovered without interrupting the pultrusion process and without damaging the resulting composite structures. Correspondingly, a composite structure is provided according to the present invention which has a protective sleeve surrounding the portion of the lead which extends through the end of the composite body. As such, the protective sleeve protects the lead during the fabrication process by protecting the lead during the separation of the composite structures and the recovery of the embedded lead.

  • Patent number: 6047094
    Abstract: A structure is provided that includes a structural element and a composite carrier assembly associated with the structural element, such as by being embedded therein, wherein the compatible carrier assembly includes a composite carrier and a sensor disposed with the composite carrier. By embedding the composite carrier assembly within a structural element, the sensor, such as a fiber optic sensor, will measure the conditions, such as the strain, temperature or the like, to which at least a portion of the structural element is subjected in a manner which averages the measurements over a distance greater than the predetermined dimensions of the sensor element. In addition, the thermal, mechanical and electrical characteristics of the composite carrier can be precisely tailored, such as to match those characteristics of the structural element in which the composite carrier is to be embedded, so that the composite carrier will be compatible with the host material of the structural element.

  • Patent number: 4019499
    Abstract: A compression implant to resist the flow of urine through the urethra comprising a cap, an external planar pressure face on the cap, a base, an external bearing face on the base, and a peripheral wall continuously interconnecting the cap and the base. A peripheral fold in the peripheral wall enables the face to move toward and away from the base by changing the shape of the fold without elastic stretching of the material which forms the wall. The cap, base and peripheral wall together define an internal cavity which can be filled with an adjustably variable amount of fluid whereby to adjust the firmness of the capsule and thereby to adjust the force which it exerts against the urethra after implantation.
