Publication number: 20190232984Abstract: An emergency arrest device for a zip line is disclosed. The emergency arrest device is designed to tension and control a slide-and-grip knot, such as a Prusik knot, that is tied on the zip line. The device includes a mirror-image set of sidewalls, a front endwall connected between the pair of sidewalls at a front end of the device, and a rear endwall connected at a rear end of the device. The front and rear endwalls have openings sized to permit passage of the zip line therethrough. A tail fixation assembly including a clamp is mounted in the rear of the device. A knot-body control assembly is mounted in the front of the device. The knot-body control assembly includes arms that are resiliently biased to push the body of the slide-and-grip knot rearwardly when the device is impacted.Type: ApplicationFiled: January 31, 2019Publication date: August 1, 2019Inventor: Donald Andrew Hackett

Publication number: 20190232985Abstract: A linear-motion brake system uses a fixed block, a moving block, and a linear-motion resistance assembly to decelerate a user who is tethered to the system via a force-transfer line. The linear-motion resistance assembly is a compressible component that exerts a force on the force-transfer line that opposes the force generated by the user traveling along a zipline. The moving block and the fixed block are positioned on opposite sides of the linear-motion resistance assembly, such that the moving block compresses the linear-motion resistance assembly when impelled by the force-transfer line. The force transfer line is threaded through a pair of guide channels that run along the linear-motion resistance assembly. One end of the force-transfer line is tethered to the fixed block while the opposite end is tethered to the user. Thus, the user's motion is transferred to the moving block and resisted by the linear-motion resistance assembly.Type: ApplicationFiled: January 31, 2019Publication date: August 1, 2019Inventor: Todd Domeck

Publication number: 20190232987Abstract: An extraction unit (121) determines, by using a fixed composition file, a fixed composition including a car having a specified equipment installed thereon as a fixed specified composition. The extraction unit determines, by using an operation composition file, an operation composition including the fixed specified composition as an operation specified composition. The extraction unit extracts, from an environment file, environment information corresponding to a set of a specified time and the operation specified composition. A conversion unit (122) converts, by using the environment information, state information indicating the state of the specified equipment at the specified time to comparative information indicating the state of the specified equipment in a reference environment. An evaluation unit (123) compares the comparative information with reference information. Then, the evaluation unit evaluates the state of the specified equipment at the specified time based on the comparison result.Type: ApplicationFiled: August 10, 2016Publication date: August 1, 2019Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Masafumi YAMADA, Takeshi TAKEUCHI, Norimitsu NAGASHIMA
