Abstract: In some implementations, a computing device can be configured for users (e.g., user devices) that are detected nearby the computing device. For example, the computing device may be a communal device configured for a single user but generally used by multiple users. The communal device can discover when a known (e.g., authorized, trusted, etc.) user device is near the communal device and obtain personalization data from the nearby user device. The communal device can configure the communal device based on the personalization data to personalize an activity hosted by the communal device for the user of the nearby user device. To protect the user's personalization data, the communal device can delete the user's personalization data when the activity hosted by the communal device is terminated.

Abstract: An overload protection mechanism for use with an electrically hedge trimmer includes a transmission ring gear, a roller disposed in the transmission ring gear, a transmission shaft disposed in the transmission ring gear and eccentrically connected with two rocker arms, and a clutch member movably sleeved on the transmission shaft. When excessive resistance is applied to the rocker arms, the clutch member is pushed by the roller to compress an elastic member. This allows the transmission ring gear to be idled. When the resistance applied to the rocker arms is smaller than the rebound force provided by the elastic member, the clutch member is engaged with the roller, such that the transmission ring gear drives the transmission shaft to rotate through the clutch member. Thus, the overload protection mechanism of the present invention carries out overload protection to the motor for extending the life of the motor.

Abstract: A foldable tile saw suitable includes a base unit including a seat body and a water tank, a connecting unit including a connecting arm having a first section and a second section, and a saw unit including a saw blade seat and a saw blade. The connecting arm can rotate between an approaching position and a distant position relative to the water tank around a first axial line to generate positioning. The saw blade seat has a connecting portion and a cutting portion. The saw blade seat can rotate between a cutting position and a folded position around a second axial line relative to the water tank and generate positioning. As long as the connecting arm is rotated to the approaching position, and the saw blade seat is rotated to the folded position, the cutting portion can be approached to the water tank, so the storage space can be effectively reduced.
