  • Patent number: 11938074
    Abstract: A neck supporting exoskeleton is configured to be worn by a person to support the person's head during backward extension motions of the person's neck. The neck supporting exoskeleton may comprise a torso frame configured to be coupled to the person's torso, a head pillow configured to contact the rear portion of the person's head during backward extension motions of the person's neck, a linkage allowing for relative motion between the head pillow and the torso frame in the sagittal plane of the person, and an actuator configured to impose a supporting force onto the head pillow. When the person's neck extension angle increases beyond an engagement angle, the actuator causes the linkage to impose a supporting force onto the head pillow resisting the backward extension motion of the head pillow and the person's head relative to the torso frame thereby providing a support for the person's head.

  • Publication number: 20230136487
    Abstract: A wireless data transmission method includes sending by an external device a data packet; receiving by a primary device and a secondary device the data packet sent by the external device. When the secondary device does not receive the data packet sent by the external device correctly, sending by the secondary device a feedback signal to the primary device. When the secondary device receives the data packet sent by the external device correctly, not sending the feedback signal. The method further includes detecting by the primary device if the secondary device has sent the feedback signal. When the primary device receives the data packet successfully and detects that the secondary device has not sent the feedback signal, sending by the primary device an ACK signal to the external device; otherwise, sending by the primary device a NACK signal to the external device.

  • Patent number: 11515213
    Abstract: A method for forming a semiconductor device. A substrate having a first region and a second region surrounding the first region is provided. The first region includes a first active area and a first gate. A dummy pattern is disposed on the substrate within the second region around a perimeter of the first region. A resist pattern masks the second region and includes an opening that exposes the first region. An ion implantation process is performed to implant dopants through the opening into the first active area not covered by the first gate within the first region, thereby forming doped regions in the first active area. A resist stripping process is performed to remove the resist pattern by using a sulfuric acid-hydrogen peroxide mixture (SPM) solution at a temperature that is higher than or equal to 120˜190 degrees Celsius. The substrate is subjected to a cleaning process.

  • Patent number: 10992345
    Abstract: Disclosed is a method for low voltage broadband power line carrier communication; when transmitting a physical layer protocol frame, short preambles are first transmitted to undergo automatic gain control, channel estimation, coarse-grained frequency offset compensation, and symbol synchronization; and then long preambles are transmitted to undergo automatic gain control, channel estimation, fine-grained frequency offset compensation, and symbol synchronization. Compared with the scheme of only transmitting long preambles, the present disclosure combines transmissions of short preambles and long preambles, which thus may quickly and accurately implement frequency offset compensation, automatic gain control, symbol synchronization, and channel estimation without sacrifice of precision, thereby achieving quick convergence, reducing resource overheads and time overheads, and enhancing system performance.
