Patent number: 11482777Abstract: A portable information handling system rotationally couples main and lid housing portions to each other with a hinge having opposing faces. One of a first or second antenna set disposed on the opposing faces is selected to support wireless communication by a radio disposed in the housing based upon the rotational orientation of the hinge. Optimal antenna selection is confirmed by comparing return signal strength indicator or bit rate error of the first and second antenna sets.Type: GrantFiled: June 3, 2019Date of Patent: October 25, 2022Assignee: Dell Products L.P.Inventors: Jace W. Files, John T. Morrison, Vinh X. Bui

Patent number: 9753591Abstract: Identifying characteristics integrated in a totem and detected by a capacitive display mat are applied to perform functions in response to end user inputs. Identifying characteristics include capacitive feet integrated in a totem bottom surface with identifying features including varying capacitive values for the feet, varying pad sizes and shapes, varying pad patterns and varying capacitive oscillation frequencies. In one embodiment, the surface area of the totem in contact with the capacitive mat varies depending upon the pressure placed on the totem to alter the shape of a compressible material disposed at the bottom surface.Type: GrantFiled: April 21, 2015Date of Patent: September 5, 2017Assignee: Dell Products L.P.Inventors: Vinh X.

Patent number: 9720446Abstract: Desktop surface references are selected and applied to define a coordinate system for calibrating projected visual images and end user inputs at the projected visual images. For example, a desktop edge is detected with the depth camera by the increase in detected distance along the axis from the depth camera to the desktop edge, and then the desktop edge is used as an origin for a coordinate system that defines a projection area for presenting a user interface. Monitoring end user inputs and projected outputs relative to the desktop edge aids in coordinating interactions by a user through the projected user interface in the event the camera or projector move relative to the desktop surface.Type: GrantFiled: April 21, 2015Date of Patent: August 1, 2017Assignee: DELL PRODUCTS L.P.Inventors: Vinh X.

Publication number: 20140282228Abstract: A method and system for managing the active area of a touch-sensitive display is disclosed. A request to resize the active area of a touch-sensitive display is received from a user in the form of a user gesture. The relationship of the current dimensions of the active area to the inside dimensions of a bezel associated with the touch-sensitive display is determined. The request is then processed to initiate active area resizing operations. If the dimensions of the active area are coincident with the inside dimensions of the bezel, then the dimensions of the active area can be reduced. If the dimensions of the active area are not coincident with the inside dimensions of the bezel, then the dimensions of the active area can be increased.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: DELL PRODUCTS L.P.Inventors: Gerald R.

Patent number: 7747878Abstract: Audible noise related to power state transitions of an information handling system processing component, such as the central processing unit, is reduced by randomizing the time between power state transitions. Random power state transitions are managed by an operating system module that tracks the transitions and selects random times for subsequent transitions within a predetermined time range. Alternatively, an arbitrating circuit intercepts power state transition commands and arbitrates their communication at random times. Random power state transitions reduces audible noise by spreading the frequency of the noise-causing power transition events over a wider band.Type: GrantFiled: September 6, 2005Date of Patent: June 29, 2010Assignee: Dell Products L.P.Inventors: Nikolai V.
