    Abstract: An emergency warning system includes a plurality of emergency annunciators for installation in a physical zone, a zone controller and a master controller. Each emergency annunciator is operable to independently and periodically perform a self-test for verifying its capacity to annunciate an emergency and to transmit a report of the self-test result. The zone controller is operable to receive the reports from each emergency annunciator and generate and transmit a zone report representing a consolidation of the received reports. The zone controller can also transmit an activation command to the emergency annunciators based on a received zone activation command. A master controller is operable to receive the zone report and generate therefrom a user notification indicative of the self-test results as well as to transmit the zone activation command in response to a trigger condition. The system may be easily installable through addition of the above components to an existing computer networking infrastructure.

    Abstract: A system for controlling operation of a motor drive during fast start-up of an induction motor is disclosed. The system includes an AC motor drive having a PWM inverter and a control system to generate a command signal to cause the PWM inverter to control an output of the AC motor drive. The control system includes a start-up modulator that is selectively operable during start-up acceleration of the AC motor, the start-up modulator programmed to determine a motor current applied to the AC motor and a voltage of a DC bus, generate a first frequency offset that causes a frequency reference of the command signal to be decreased when the motor current is greater than a reference current threshold, and generate a second frequency offset that causes the frequency reference of the command signal to be increased when the DC bus voltage is greater than a reference voltage threshold.

    Abstract: Computer systems and methods allow users to annotate content items found in a corpus such as the World Wide Web Annotations, which can include any descriptive and/or evaluative metadata related to a document, are collected from a user and stored in association with that user. Users are able to annotate and view their annotations for any document they encounter while interacting with the corpus, including hits returned in a search of the corpus. Users are also able to search their annotations or to limit searches to documents they have annotated. Metadata from annotations can also be aggregated across users and aggregated metadata applied in generating search results.

    Abstract: An apparatus and system for compensating for various load situations in a turbine includes the use of one or more deployable devices configured to extend an air deflector outwardly from a surface of a rotor blade. The air deflector may subsequently be retracted into the rotor blade once the load falls below a certain threshold. Mechanisms for extending and retracting the air deflector may include pneumatic, hydraulic and/or electromechanical devices. Air deflectors are generally configured to modify the air flow around the rotor blade to increase or decrease power generation, or reduce loads so that the risk of potential damage to components of the wind turbine is minimized. Deflectors may be positioned at various chordwise stations including leading-edge, mid-chord, and trailing-edge locations on the upper and lower surfaces at spanwise positions. Accordingly, a plurality of devices can be actuated to aerodynamically control rotor performance and loads based on wind conditions.

    Abstract: A fluid infusion system including a pocketable pump housing with a reservoir cavity with helical coupling features. The system further has a reservoir with an open end that is removable from the reservoir cavity. A removable cap coupled to the housing is also included in the system. The cap has corresponding coupling features, an exterior surface and a tab. The corresponding coupling features couple the cap to the housing while the tab is a ridge that extends away from the exterior surface. The tab has a port to accommodate flow from the reservoir and the port defines an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the housing. The system further has a removably coupled guard with a slot defined to immobilize rotation of the tab about the axis of rotation.
