Abstract: A system includes a processor in communication with one or more sensors, wherein the processor is programmed to receive data including one or more of real-time current information, real-time voltage information, or real-time vibrational information from a run-time device, wherein the run-time device is an actuator or electric dive, and utilize a trained machine learning model and the data as an input to the trained machine learning model, output a sound prediction associated with estimated sound emitted from the run-time device.

Abstract: Device for laser surveying of an environment A device for surveying an environment by time-of-flight measurement of laser beams reflected therefrom comprises a beam deflection device having at least one mirror surface which can be rotated or oscillated about an axis of rotation which is non-normal to the mirror surface. The device further comprises a first laser transmitter with associated first laser receiver, and a second laser transmitter with associated second laser receiver. The transmission and reception directions of the first and second laser transmitters and receivers lie parallel to one another in pairs and at different angles to the axis of rotation. The first laser receiver is spaced apart from the first laser transmitter and the second laser receiver is spaced apart from the second laser transmitter, in each case in the direction of the axis of rotation.

Abstract: A collecting bag is for receiving material to be collected and has a receiving space delimited by a woven-fabric cloth and is delimited by outer edges of the collecting bag. The woven-fabric cloth of the collecting bag is at least partially air-permeable. The receiving space has an inlet opening for a conveying airflow which supplies the material to be collected, and an outlet opening for at least partially discharging the conveying airflow into the environment. The inlet opening is provided on a first edge of the collecting bag, and the emptying opening is provided on a second edge. The first and second edges are opposite one another at a spacing and are interconnected via longitudinal edges of the collecting bag. The outlet opening for at least partially discharging the conveying airflow is disposed in a side wall of the collecting bag, between the emptying opening and the inlet opening.

Abstract: A telescopic drive shaft in a protective tube of a handheld work apparatus has one end connected to a rotational drive and the other end thereof to a driven tool. The drive shaft includes a rigid shaft segment and a connecting section. The rigid shaft segment has a hollow shaft end portion and an engagement length (E) of the connecting section engages therein. The engagement length (E) and the length of the hollow shaft end portion mutually overlap to form a joining section. The hollow shaft end portion is deformed for connecting the connecting section to the rigid shaft segment. The material of the hollow shaft end portion is compressed over its entire periphery and deformed so that the material of the hollow shaft end portion is radially displaced and is pressed in a rotative manner onto the engagement length (E) to produce a balanced, loadable connection.

Abstract: A handle device, in particular for a hand tool, includes a grip unit and a fastening unit. A resiliently elastic damping unit is arranged between the grip unit and the fastening unit. The damping unit is configured to transmit a vibration that occurs on the fastening unit in the operating state of the handle device to the grip unit in an at least partially damped manner so that a user is decoupled at least partially from the vibration. An overload protection unit is configured to protect the damping unit from damage in the event of an overload state occurring on the grip unit or on the fastening unit by diverting at least part of a force flux between the fastening unit and the grip unit to an additional force flux path as a bypass during the overload state.
