A computer mouse with an adjustable palm rest includes a main housing defined with a longitudinal direction and a traverse direction and has a carriage. A connecting base is rotatably connected to the carriage along a first axis. A supporting casing has a front wall and a rear wall. A palm-resting cover is fixed to the supporting casing. The front wall is closed to the connecting base. The supporting casing is rotatably connected to the connecting base along a second axis. The supporting casing can be arranged at different oblique angles related to the connecting base. A positioner chain is formed on a surface of the connecting base or the supporting casing and has a plurality of positioning dimples. A positioning assembly abuts against one of the dimples and retains the supporting casing at one of the oblique angles related to the connecting base.

The invention relates to a control device with a stator unit fastened via a stator connection to a support body, and a rotor unit rotatable about the stator unit. The rotatability of the rotor unit about the stator unit can be influenced in a targeted manner by means of a braking device. For its rotatability about the stator unit, the rotor unit is mounted on the support body by means of at least one bearing unit of a bearing device, so that a force acting on the rotor unit from radially outside can be diverted via the bearing unit into the support body, bypassing the stator unit and the stator connection.

Methods and systems for determining a displacement of a peripheral device are provided. In one example, a peripheral device comprises: an image sensor, and a hardware processor configured to: control the image sensor to capture a first image of a surface when the peripheral device is at a first location on the surface, the first image comprising a feature of the first location of the surface; execute a trained machine learning model using data derived from the first image to estimate a displacement of the feature between the first image and a reference image captured at a second location of the surface; and determine a displacement of the peripheral device based on the estimated displacement of the feature.

A wheel device is applied to a mouse and includes a supporter, a wheel module, a lighting unit and a sheltering component. The wheel module includes a wheel axle, an encoder and a wheel component. The wheel axle includes an axle body, a wheel surface and a wheel frame. The axle body is rotatably disposed on the supporter and on center of the wheel frame. The wheel surface is located on an outer surface of the wheel frame. The encoder is connected to the axle body to detect rotation parameters of the wheel axle. The wheel component covers the wheel surface. The lighting unit is disposed on the supporter and inside the wheel frame, and emits an illumination beam to the wheel module. The sheltering component is disposed on the supporter and covers the lighting unit to prevent the illumination beam from leakage through two sides of the wheel component.

A roller module includes a supporting seat, a scroll wheel, a linkage rod, a torsion spring, a first magnet, a second magnet and a coil. The scroll wheel is installed on the supporting seat. The linkage rod includes a fulcrum segment, a resisting segment and an effort segment. The torsion spring is connected with the resisting segment. The first magnet is arranged between the second magnet and the effort segment. The coil is arranged around the second magnet. When the roller module is in a tactile mode, the first magnet and the second magnet are close to each other, and the torsion spring exerts a pulling force on the resisting segment. Consequently, the resisting segment is contacted with a toothed region of the scroll wheel. When the roller module is in a non-tactile mode, the resisting segment is moved away from the toothed region.

A mouse device includes a body, a cover plate, a covering layer, and an adhesive layer. The cover plate is disposed on the body and includes a button. The covering layer covers the cover plate, and the material of the covering layer is different from the material of the cover plate. The adhesive layer is bound between the cover plate and the covering layer, and the adhesive layer has a hollow portion corresponding to the button.

A mouse includes a main housing, a key structure, and a pressing force adjusting component. The key structure has a connecting end, a free end, and an elastic section. The connecting end is connected to the main housing, and the elastic section is located between the connecting end and the free end. The pressing force adjusting component is movably disposed on the main housing and has a limiting portion, and the limiting portion limits elastic deformation of the elastic section. A location of the pressing force adjusting component on the main housing is adapted to be changed to change a location of the limiting portion at the elastic section.

A mouse device includes a middle frame, a switch, a button plate, a slidable element and an elastic element. The middle frame includes an opening part and a first hook. The first hook is located beside the opening part. The switch is fixed at a position under the middle frame. The switch includes a triggering part. The button plate is located over the middle frame. The button plate includes a pressing rod. The pressing rod is penetrated downwardly through the opening part. The pressing rod includes a receiving groove and a first sleeve. The receiving groove is located over the first sleeve. The first sleeve includes a perforation. The slidable element includes a second sleeve and a second hook. The second sleeve is installed within the first sleeve. The second hook is engaged with the perforation. The elastic element is disposed within the second sleeve.

A configuration system uses multiple depth cameras to create a volumetric capture space around an electronically controllable industrial machine or system, referred to as a target system. The output of the cameras is processed to create a live 3D model of everything within the space. A remote operator can then navigate within this 3D model, for example from a desktop application, in order to view the target system from various perspectives in a live 3D telepresence. In addition to the live 3D model, a configuration system generates a 3D user interface for programming and configuring machines or target systems within the space in a spatially coherent way. Local operators can interact with the target system using mobile phones which track the target system in augmented reality. Any number of local operators can interact with a remote operator to simultaneously program and configure the target system.
