  • Publication number: 20240076163
    Abstract: A method of learning a rescue time period by an elevator system (101). The elevator system (101) includes an elevator car (103) moved by a machine (111) and a machine brake (120), arranged such that braking of the machine (111) by the machine brake (120) brakes motion of the elevator car (103). The method includes releasing the machine brake (120) for at least one test time period, at the end of which the machine brake (120) is engaged, detecting a corresponding at least one maximum travel speed of the elevator car (103) reached as a result of releasing the machine brake (120) for each at least one test time period, checking whether each at least one maximum travel speed is an acceptable speed, and setting the rescue time period based upon said checking.

  • Publication number: 20220043411
    Abstract: A method for low-latency generation and input of sensor data for control units or control unit networks includes: computing, by a simulator system or device, environmental data sets at a simulation frequency using an environment model of a virtual environment scene, wherein each environmental data set is associated with a respective point in time in an overall simulation time at which point in time the respective environment data set is available for further processing; and executing, by the simulator system or device or by at least one additional system or device, at least one sensor simulation model, wherein the at least one sensor simulation model generates sensor data sets at a sampling frequency, based on the environmental data sets, for further processing by at least one control unit, wherein each sensor data set is associated with a respective start time and respective time of completion in the overall simulation time.

  • Patent number: 9599467
    Abstract: The invention relates to a method for testing the proper functionality of an elevator, in which a car (3) is movable in an elevator shaft having an elevator shaft excavation space, and a characteristic value is ascertained under predefined test conditions to determine the proper functionality of the elevator. To simplify the method, it is proposed according to the invention that a change of the distance (A) between a car lower side and a fixed measuring point in the elevator shaft excavation space be measured to ascertain the characteristic value.

  • Publication number: 20140058700
    Abstract: This invention relates to a method for testing the proper working order of an elevator, having the following steps: providing an acceleration measuring device (5) of an elevator car (3) that can be moved in a z direction, an acceleration of the car (3) in the z direction being measurable dependent on time using the acceleration measuring device (5); providing an optical distance measuring device (7) for measuring a distance of the car (3) or of the counterweight (4) relative to a fixed point dependent on time; simultaneously detecting first values that are measured using the acceleration measuring device (5) and second values that are measured using the distance measuring device (7); and producing a travel curve (Ak, Bk) that reproduces the movement of the car (3) using the first and second values.

  • Patent number: 6921369
    Abstract: A mobile ergospirometry system including a portable measurement unit that can be attached to a subject and that incorporates a mouthpiece or mask to collect respiratory gas, a sensor for the volume or amount of gas as well as sensors to determine the CO2/O2 concentration in the respiratory gas, a signal processing unit, and a telemetry module. The system further includes a computer-assisted base station having a telemetry unit to create a wireless connection to the telemetry module. In the system a bidirectional transmission route to the telemetry unit is set up by the telemetry module to transmit data and commands, for which purpose a transmitter and receiver subassembly is provided in each case, so that from the base station it is possible to communicate to the subject online information or requirements for operation of the measurement unit and/or the progress of the test.
