Patent number: 11913812Abstract: A control assembly for controlling a speed or torque of operation of an electric device includes a control assembly housing, a magnetic sensor, a magnetic element; and an actuator. The actuator moves relative to the control assembly and, responsive to that movement, the magnetic sensor and magnetic element are moved relative to each other between a first position and a second position so that the magnetic sensor senses a first magnetic field reading when in the first position and senses a second magnetic field reading when in the second position. A control module is operably connected to the magnetic sensor and configured for controlling the electric device, and a magnetic shielding element is positioned within the control assembly housing to alleviate a magnetic signal source external to the control assembly from interfering with the sensing by the magnetic sensor.Type: GrantFiled: November 22, 2021Date of Patent: February 27, 2024Assignees: Defond Electech Co., Ltd., Defond Components LimitedInventors: Cheng Chen Nieh, Chiu Keung Loong, Wai Man Wong

Publication number: 20130332526Abstract: Some embodiments provide tools that allow a user to share content on one device with multiple other users using different devices. The content sharing tools allow the user to (1) create a shared stream that represents a set of shared content and (2) invite one or more recipients to subscribe to the shared stream. When a recipient subscribes to the shared stream, the set of content is streamed across one or more of his or her devices. In some embodiments, a control server facilitates the sharing of content by managing control data associated with different shared streams.Type: ApplicationFiled: September 29, 2012Publication date: December 12, 2013Applicant: APPLE INC.Inventors: Timothy S. Hurley, Guido Neitzer, Mark L. Ritchie, Richard J. Scorer, Jason Te Whau, Erik Torres Bergman, Li Wang, Raymond Wai-Keung Wong, Peter W. Roman, Joshua B. Dickens

Patent number: 5930396Abstract: A method of generating halftone output on an output device. The method includes retrieving at least one table which associates gray levels with halftone results for a region of an output frame including more than one pixel, determining a reference gray level for a tile of an output frame including more than one pixel, using the at least one table to determine a halftone result for the reference gray level, storing the halftone result for the reference gray level to the tile of the output frame, and delivering the output frame to the output device. The table may be generated from a set of thresholds, which may be a threshold array. A first table may associates gray levels with codes and a second table may associates codes with halftone results, and the method may include converting the reference gray level to a reference code with the first table and converting the reference code to the halftone result for the reference gray level with the second table.Type: GrantFiled: April 22, 1997Date of Patent: July 27, 1999Assignee: Adobe Systems IncorporatedInventors: Edward Reid Fiala, Raymond Wai-Keung Wong
