Abstract: A server of a system is configured to transmit a message from a first device that includes a conference identifier (ID) and a user ID to a second device to connect the second device to an ongoing audio conference bridge call without interrupting the audio conference bridge call. By providing the conference ID and the user ID, host privileges associated with the user associated with the user ID are transferred to the second device. By transferring the host privileges to the second device, the user can, via the second device, view the participant roster and add or remove participants from the audio conference bridge call.

Abstract: The present invention discloses a stiffness-variable joint actuator with motor-reducer integration, and belongs to the field of robots. The stiffness-variable joint actuator includes: a torque motor, which includes a casing, a stator, a rotor, pin gears, and pin gear rollers; and a reducer core, which includes cycloidal gears, a planetary carrier, and an eccentric shaft. The motor is connected to a cycloidal-pin gear reducer, thereby achieving the technical effect of enhancing the impact resistance and reverse actuation capability of the actuator. The rotor is disposed outside the stator, the eccentric shaft is connected to the rotor, and the reducer is disposed inside the motor, thereby achieving the technical effect of integrating the motor and the reducer and reducing the axial dimension of the actuator.

Abstract: The invention relates to a device for testing the precision retaining ability and fatigue life of RV reducer. The device includes a workbench, a mounting bracket base, a upper pressure plate for the mounting bracket, a servo motor, a mounting fixed sleeve, a tested RV reducer, a temperature sensor, an extension arm, a simulated swing arm, two counterweight blocks named the first and second counterweight block, the first displacement sensor, a sensor holder, a sensor protector, a detection rod, and the second displacement sensor. The device is equipped with two counterweight blocks at the end of the simulated swing arm to simultaneously provide variable loaded torque and loaded bending moment to the RV reducer. The first displacement sensor is placed under the counterweight block to measure the positioning accuracy and repeat positioning accuracy of RV reducer. The second displacement sensor is placed under the detection rod to measure the bending stiffness of RV reducer.

Abstract: The invention relates to a testing device for material wear of cycloidal gear and needle bearing of RV reducer, comprising: an upper cover (1), a lower cover (2), two sliding shafts (3 and 3?), two connecting shafts (4 and 4?), a driven shaft component (5), two copper sleeves (6 and 6?), two nuts (7 and 7?), two disc springs (8 and 8?), an eccentric shaft component (9), a needle bearing (10), two planetary gears (11 and 11?), two cycloidal gears (12 and 12?), and a motor assembly (13). The device can be installed on various industrial platforms. The motor drives the planetary gear to rotate, and then drives the eccentric shaft to rotate. The first bearing hole of the cycloidal gear fits with the needle bearing and forms a revolute pair with the eccentric shaft. Owning to the eccentric shaft, the cycloidal gears (12 and 12?) are driven to swing. The other bearing hole fits with the sliding shaft (3 and 3?) and the connecting shaft (4 and 4?) to form a loaded rolling friction pair.
