  • Publication number: 20250341862
    Abstract: A wrist-wearable device comprises a pivoting loop slider that is coupled to a first band and configured to receive a second band, the pivoting slider is configured to pivot around the end of the first band, such that when the pivoting slider has a first position relative to the end of the first band the pivoting slider provides a first clamping force on the second band of the wrist-wearable device. The first clamping force is configured to provide large adjustments to the tightness of the wrist-wearable device about a wrist of a user. When the pivoting slider has a second position relative to the end of the first band, the pivoting slider provides a second clamping force on the second band. The second clamping force is greater than the first clamping force and provides finer adjustments to the tightness of the wrist-wearable device about a wrist of the user.

  • Publication number: 20250134438
    Abstract: An example wearable electronic device includes a compute core with a skin contact surface and a cavity region that houses: a battery, an electrode located at the skin contact surface configured to sense neuromuscular signals, an analog front end (AFE) configured to partially process the sensed neuromuscular signals into partially processed neuromuscular signals, a printed circuit board (PCB), and a metallic base plate (MBP). The PCB receives the partially-processed neuromuscular signals and determines gestures based on the partially processed neuromuscular signals. The MBP provides an electrical ground for the electrode and electrically shields the electrode from electrical and magnetic noise that is generated at least partially from at least one of the PCB and the battery. The AFE is placed on a first side of the MBP and the PCB is placed on a second side that is opposite to the first side of the MBP.

  • Publication number: 20250010659
    Abstract: A socket includes a head part 1 and a body 2, characterized in that an inside of a first socket hole 21 of the body 2 is provided with an inner plastic sleeve 3 attached to an inner wall thereof in a replaceable way, wherein, the head part 1 can dock with an internal angle head nut or a bolt to drive its rotation. The inner plastic sleeve 3 mats with a nut or bolt and drive its rotations. The inner plastic sleeve 3, as provided inside the body 2, not only can it increase the friction in contact with the nut or bolt, which increases the efficiency of the socket operation, the user can also replace the inner plastic sleeve 3 when the inner plastic sleeve 3 is damaged or slips after multiple uses. As the user only need to replace the inner plastic sleeve 3 instead of replacing the entire metal socket, the present invention significantly reduces the operation costs, saves social resources, and avoid unnecessary waste.
