Abstract: A system and method for monitoring one or more environmental conditions at a construction Site. Some embodiments include a system and method for sending a notification to a client device based on a trigger condition. The system may include a computer server including a web server and a database; a Coordinator and Aggregator Gateway (CAG) deployed at the construction site and In communication with the web server and a global position system (GPS) network; and one or more Wireless Sensor Nodes (WSNs) deployed at the construction site and in communication with the CAG, each of the WSNs including one or more sensors configured to measure an environmental condition of the construction site.

Abstract: A fuel tank for receiving a fluid in a motor vehicle. The fuel tank includes an outer wall forming an internal space for receiving the fluid. At least one volume element is arranged in the internal space for receiving air, and an opening that is a gas-guiding line between the volume element and the environment of the tank is for changing the volume of the volume element. The at least one volume element is formed at least partially as bellows.

Abstract: The present invention comprises a line tool device used for catching a line therein. The present device is generally comprised of two fixed plates, a fixed clamp, a movable clamp, a forward extension and a grip. The fixed clamp is located between and attached to the two fixed plates. The fixed clamp has one edge that contains a plurality of teeth. A movable clamp is pivotally attached to one of the fixed plates. The movable clamp also has one edge that contains a plurality of teeth. When the movable clamp pivots to a closed position the teeth attached to the fixed clamp and the teeth attached to the movable clamp meet and interlock. Additionally, the movable clamp contains a spring that allows the two sets of teeth to meet only when a force is applied to the device and a hand opening which allows the user to grasp the movable clamp. A guide is attached between and to the forward facing side of the two fixed plates. The forward extension contains at least one line guide that a lightweight line can pass over.

Abstract: A powered rope ascender that supports a person or a load while ascending a vertical rope. The rope ascender has a motor driven capstan drum that engages the rope. A pinch roller grips the rope against the capstan drum. A load limiting assembly releases the grip by the pinch roller when the load supported by the ascender exceeds a predetermined amount. A centrifugal clutch reduces starting torque required by the motor and the outer drum of the centrifugal clutch interacts with a brake to hold position on the rope. For heavy loads a motion activated brake is used. Hand controls provide a freewheeling, a braking and an ascending mode of operation. A harmonic drive or planetary reduction gears provide speed reduction from the motor to the capstan drum. The powered rope ascender can be threaded on the rope without access to a rope end.

Abstract: Systems and methods for tracking employee job performance include receiving performance-related data from an employee. The performance-related data may include a schedule from the employee, a number of a demand activity performed by the employee, and a type of the demand activity performed by the employee. Systems and methods for tracking employee job performance also may include calculating a statistic related to the job performance of the employee and generating a report detailing the job performance of the employee. The report may be generated over a managerial scope received from a management user and may include the statistic related to job performance.
