Patent number: 11941298Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.Type: GrantFiled: April 19, 2022Date of Patent: March 26, 2024Assignee: MediaTek Inc.Inventors: Chih-Chieh Chou, Chia-Chun Wang, Liang-Yen Wang, Chin Chin Cheng, Szu-Chi Liu

Publication number: 20170077698Abstract: A power conversion system is disclosed. The power conversion system comprises a portable electronic device and an embedded power converting device. The portable electronic device comprises a connecting terminal and a first control unit. The embedded power converting device is partially embedded in a closed structure and configured to convert an input voltage into a DC voltage, and comprises a socket and a second control unit. The socket is partially exposed outside the closed structure for allowing the connecting terminal to be inserted therein. When the connecting terminal is inserted in the socket, the second control unit is in communication with the first control unit to acquire a required DC charging voltage for the portable electronic device and the embedded power converting device outputs a DC voltage equal to the required DC charging voltage to the connecting terminal through the socket.Type: ApplicationFiled: February 18, 2016Publication date: March 16, 2017Inventor: CHIH-YEN LIU

Patent number: 7878917Abstract: A laser aligning device is mounted on the flat side of a putter grip or other cylindrically asymmetric surface of a club grip and emits a fan shaped light sheet. The light sheet is perpendicular to the flat side of the putter grip. The light sheet projects a visible laser line on a plane such as the ground when the head is on the same plane. The alignment of the grip relative to the putter head's face can be inspected by visually inspecting the orientation of the projected line on the plane relative to the head's face. The grip can be adjusted and fixed so that it is properly oriented to the face.Type: GrantFiled: December 10, 2007Date of Patent: February 1, 2011Assignee: Newtonics Spectra Inc.Inventors: Lanny L.

Patent number: 7118488Abstract: A training putter with a laser line projecting device can be used for putting training to improve putting skill. The device is affixed to a putter head above its sweet spot, and emits a vertical light fan which projects a line on the around normal to the face of the putter head. The line is aligned with the sweet spot of the putter head and lies on the ground to connect the top of a golf ball with a target, such as a cup or a putting hole, so that alignment can be easily visualized. The device can be detached and reattached easily without any laser alignment. Furthermore, the device can be removably mounted to a user's own putter. The heat generated in the laser diode is quickly dissipated through the metal housing, the metal putter head, and the metal shaft to the surrounding air. Since proper operating temperature of the laser diode can be maintained, the laser diode will operate properly, which means the power of the emitted light will not be decreased, and the lifetime of the diode will not be shortened.Type: GrantFiled: January 21, 2005Date of Patent: October 10, 2006Assignee: Newtonics Spectra Inc.Inventors: Benny Chan, Suganda Jutamulia, Chih Yen Liu
