Abstract: Systems and methods for providing display panels with reduced visual artifacts. A display system is provided that includes a pixel array having a plurality of pixels arranged in rows and columns. The display system receives an image stream that includes a plurality of sets of image data that each represent an image to be sequentially presented by the display system. The data for each frame or set of image data is loaded into the pixel array according to a loading sequence with reduces the visual artifacts perceived by a viewer of the display system. The loading sequence may include an inside-out loading sequence which gives preference to a central region of the pixel array, a speculative preloading sequence which first loads portions of the pixel array with speculative data, or various combinations thereof.

Abstract: A shield can assembly is described. In one or more implementations, a frame is installed on a printed circuit board (PCB) by using a cross-bar connected to opposing sides of the frame to place the frame on the PCB. Subsequent to installation of the frame on the PCB, the cross-bar is removed from the frame. Once the cross-bar is removed, one or more flexible printed circuits (FPCs) are installed on the PCB. Then, a lid is connected to the frame to from a shield can over the FPCs.

Abstract: A lock for actively locking an electronic device includes an engagement member that is movable by an actuator. The actuator moves the engagement member to the locked position with a first amount of power from the power source and from the locked position to an unlocked position with a second amount of power from the power source. The engagement member will passively remain in the unlocked position or the locked position.

Abstract: Power management contracts for accessory devices are described. In one or more implementations, a power management contract is established for a system including a host computing device and an accessory device based at least in part upon power exchange conditions observed for the system. The power management contracts define operating constraints for power exchange between components of the system, including at least a power exchange direction and current limits. The host computing device and accessory devices are each configured to renegotiate the power management contract to dynamically change operating constraints in “real-time.” Additionally, different power management contracts may be associated with identifying data corresponding to different types of accessory devices.

Abstract: Accessory device power management techniques are described in which a power exchange state for a system including a host computing device, an accessory device, and an adapter is recognized. Power exchange states may be defined according to relative states of charge (RSOC) and connection status for the system components and mapped to power management control actions. Responsive to the recognition of a current power exchange state, corresponding power management control actions may be ascertained and applied to jointly manage power for the system. For instance, the host device may draw supplemental power from a power source associated with an accessory device (e.g., a battery or power adapter) or supply power for use by the accessory device according to different states. Power exchanges may also be managed in accordance with capabilities of the accessory device identified based on authentication of the accessory device.

Abstract: An electronic connector includes a base, and one or more tapered extensions protruding from the base. Each tapered extension includes a nose forming a terminal end of that tapered extension. Each tapered extension further includes first and second connection faces that form respective opposing sides of that tapered extension, and that taper toward each other from the base to the nose. Each tapered extension further includes first and second flank surfaces that form respective opposing sides of that tapered extension, and that taper toward each other from the base to the nose between the first and second connection faces. Each tapered extension further includes a first forward set of plural electrical contacts and a first rearward electrical contact located along the first connection face. Each tapered extension further includes a second forward set of plural electrical contacts and a second rearward electrical contact located along the second connection face.

Abstract: Reversible connectors for accessory devices are described. In one or more implementations, a connector cable for an accessory of a host computing device is configured such that a head of the connector cable may be plugged into a corresponding port of the host in either orientation (straight or reverse). The host computing device is configured to sample signals associated with allocated pins of the connector to detect connection of the connector to an accessory port and to ascertain an orientation of the connector. A combination of high and low values of signals conveyed via these allocated pins upon insertion of the connector may be used by a controller of the host to distinguish between different types of devices and to resolve the orientation of the connector cable. A switching mechanism of the host computing device may then be configured to automatically route signals accordingly.
