Abstract: A real-time monitoring system for skid-mounted reciprocating natural gas compressors. The system not only monitors performance and makes analytical diagnostic predictions of potentially problematic valves and such, but also has alert system for real-time monitoring, troubleshooting and diagnosing of such natural gas compressors—both locally and remotely. Operators can more efficiently and effectively manage maintenance and operation of the skid-mounted compressors with the implementation of LED equipped sensors that allow operators to locally quickly identify valves and other components requiring maintenance. Additionally, operators can remotely identify and understand deviations from optimal performance with the implementation of color-coded soft gauges.

Abstract: A dynamically adjustable weight lifting aid that eliminates hand grip strength as the limiting factor in weight lifting, including a strap and a slidable sleeve encircling the strap. The strap has a wrist loop at one end and an attachment loop at the other end. The attachment loop is suitable for removably attaching the strap to a weight bar or other handle on a weight lifting system or machine. The wrist loop is suitable for receiving a person's wrist. Specifically, the person's hand is inserted through the wrist loop, and the person's palm contacts the slidable sleeve. The wrist loop cradles the person's wrist, and the effective diameter of the wrist loop is dynamically adjustable by the person's hand by sliding the slidable sleeve in either direction along the length of the strap. The person may then lift a weight of the weight lifting system by pulling on the strap.

Abstract: A wireless end device is provided. For one embodiment, a wireless end device may comprise a sensor integrated with a telemetry device. The wireless end device may monitor the sensor for a predefined condition, and transmit a message to a controller in response to detecting the predefined condition. For one embodiment, the sensor may be a vibration or level switch, and the predefined event may be a switch closure. For another embodiment, a control system is provided comprising a controller and one or more wireless end devices.
