Abstract: A torque device employs a cylindrical housing surrounding a guidewire to provide concentric loading of the guidewire along a central axis of the housing attachable at any point along a length of the guidewire. Improved torsion of the guidewire is obtained by clamping the guidewire so that it runs along the center axis of the housing offering intuitive rotational handling (torque) of the guidewire along the torque axis.

Abstract: A drive system for multiple LED strings powered by a common line voltage. Current control circuits are connected in series with respective LED strings; each current control circuit includes a drive transistor (typically a FET) which causes a desired LED string current to be conducted. In one embodiment, the current conducted by a selected one of the LED strings is controlled by the line voltage regulation loop, while the currents conducted by the remaining LED strings are controlled by respective local current loops, thus avoiding conflicts between the local current and line voltage regulation loops. The LED string to be current regulated by the line voltage regulation loop can be determined by a variety of criteria, such as the current control circuit having the maximum FET gate voltage, the minimum FET source voltage, the minimum FET drain voltage, the maximum FET gate-source voltage, or the minimum FET drain-source voltage.

Abstract: An automation controller may wirelessly poll a plurality of remote monitoring devices configured to monitor an electric power distribution system and store monitored system data collected therefrom. The automation controller may be wirelessly coupled to the plurality of remote monitoring devices using a spread-spectrum protocol, such as Bluetooth®. The automation controller may gather the monitored system data using the Distributed Network Protocol (DNP3). DNP3 packets may be communicated as the payload of Bluetooth® packets. The spread-spectrum protocol may limit the number of devices to which the automation controller may be actively connected at one time. Accordingly, the automation controller may couple and uncouple from the remote monitoring devices in a round-robin pattern to collect the monitored system data from all of the remote monitoring devices. The automation controller may provide engineering access and/or collect relay event data using the spread-spectrum protocol and a high-bandwidth protocol.

Abstract: A system and method for customization of the settings configuration process for an intelligent electronics device is disclosed. The disclosed system and method permits the end user to customize not only the operation of an intelligent electronics device for a particular application, but also permits the end user to customize the process used to configure the settings of the device. A customized settings management user interface can be designed by an end user and can be used later during the settings configuration process for one or more intelligent electronics devices. Preferably, the customized settings management user interface will be tailored to meet application-specific objectives and to provide for a relatively more efficient settings configuration process.
