Latest Patents
One of Tokiwa's latest patents is for an analog electronic timepiece. This invention includes a stepping motor, a gear train mechanism with gears, a pointer, a drive control unit, a control content changing unit, and a pointer position adjustment unit. The design allows for operational commands to rotate the pointer to different target positions, even while another command is in progress. The control content changing unit can terminate the current control and adjust according to the new command. Additionally, if reverse rotation is being performed, the pointer position adjustment unit ensures that any discrepancies between the predicted and actual pointer positions are corrected.
Another notable patent is for an electronic timepiece and operation detection method. This invention features a rotary switch and a rotation detection unit that detects the switch's rotation at predetermined angles. A determination unit assesses whether the rotation detection is continuous based on a set number of detections within a specific time frame. When continuous detection is confirmed, a control unit executes a predetermined function, enhancing the user experience.
