Abstract: A method for performing privacy-preserving visual localization includes: determining a query segmentation map based on a query image; accessing a privacy preserved scene representation that includes labeled three dimensional (3D) representations of a scene selected from one or more segmentation classes; determining a predicted pose based on a starting pose; generating, from the predicted pose, a predicted segmentation map; and refining the predicted pose after aligning the predicted segmentation map with a query segmentation map. The above may be repeated. The refined predicted pose of the query image is output.

Abstract: A method for monitoring a chain hoist having an electric drive motor which is connected on the output side, via a friction clutch, to a transmission, wherein, via a sensor, a speed of the transmission is sensed, and the sensed speed of the transmission is compared with an operating speed of the drive motor by means of a control device. In order to achieve safe and efficient operation of the chain hoist, a vertical position of the load handling device of the chain hoist is also determined by means of the control device. The invention also relates to a chain hoist having a control device which is designed and configured to carry out the method according to the invention.

Abstract: A training system includes: a pose module configured to: receive an image captured using a camera; and determine a 6 degree of freedom (DoF) pose of the camera; and a training module configured to: input training images to the pose module from a training dataset; and train a segmentation module of the pose module by alternating between: updating a target distribution with parameters of the segmentation module fixed based on minimizing a first loss determined based on a label distribution determined based on prototype distributions determined by the pose module based on input of ones of the training images; updating the parameters of the segmentation module with the target distribution fixed based on minimizing a second loss determined based on a second loss that is different than the first loss; and updating the parameters of the segmentation module based on a ranking loss using a global representation.

Abstract: A shut-down buffer for a lifting device, in particular a chain hoist, includes two opposing end surfaces and at least two mutually spaced web elements extending between the end surfaces. The shut-down buffer is defined by the end surfaces, between which a through-opening for passage of a load-bearing element of the lifting device extends through the shut-down buffer.

Abstract: An assembly kit for cable winches, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, where the assembly kit includes various transmission housing parts for the transmission unit in order to enable the assembly of a cable winch in a C shape or in a quasi-coaxial shape. A method for converting a cable winch, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, between a C-shape arrangement and a quasi-coaxial-shape arrangement, for which purpose the transmission unit, in the case of the use of different housings, in particular specific housing shells that can be assembled in order to form the different housings, is assembled differently for the C shape or coaxial shape while the same parts, in particular identical shafts, are used within the particular housing.

Abstract: A chain block with a drive motor (2) with a motor shaft (11), which is connected at the take-off side via a slip clutch (50) to a transmission input shaft (14), having a first gear (18a) and mounted in a housing (1) by pivot bearings (13, 13a), of an at least one-stage transmission (3). In order to create a simple design of chain block with a slip clutch, the transmission input shaft (14) is to be mounted floating in the pivot bearings (13, 13a) in order to change the frictional force of the slip clutch (50).

Abstract: The invention concerns a chain pulley block with a chain wheel for positive-locking transmission of the lift force to the chain and a chain guide arranged in the region of the chain wheel, for guiding the chain, especially a round-link chain, on the chain wheel. In order to make it fast, easy and inexpensive to replace wearing parts, such as chain (3), chain wheel (4) and chain guide (2), it is proposed that the chain guide (2), the chain wheel (4) and the chain (3) be assembled into a structural unit (1), which is removably fastened to the chain pulley block (7).

Abstract: A running gear for hoists and suspended loads has a running rail with two spaced-apart travel tracks that support axially spaced-apart running wheels. An electric motor is coupled to a self-locking worm gear for directly driving one of the running wheels. The running wheels are rotatably supported in a frame to which an assembly for hoisting suspended loads is secured. In order to prevent the running gear from rolling and pitching during braking, which can cause increased wear of the running gear and the running rail, a control unit is provided which is operatively connected to the electric motor and determines a start-up rate during the start-up phase of the motor from an average increase of the motor torque as a function of time, and decreases the motor torque as a function of time at a slower rate than the start-up rate for slowing down the running gear.
