Abstract: A manipulator for a surgical instrument may comprise an instrument holder coupled with the surgical instrument and rotatable in a plane that passes through a remote center. The manipulator may also comprise a linkage assembly coupled to the instrument holder to limit motion of the instrument holder to rotation about an axis that intersects the remote center. The linkage assembly may comprise a first linkage arm comprising first and second pulleys. Each pulley may comprise first and second drive tracks which are substantially co-planar. The first linkage arm may also comprise a first drive member section extending between the first drive tracks of the pulleys and a second drive member section extending between the second drive tracks of the pulleys. The first drive member section may be wound around the first pulley in a first direction and the second drive member section may be wound around the first pulley in an opposite direction.

Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

Abstract: Systems and methods for programming an electronic display in a double-row manner are provided. A system may include processing circuitry that generates image data and an electronic display that programs multiple rows of display pixels with different pixel data of the image data at the same time. This may allow double-row interlaced driving to reduce or eliminate image artifacts due to intra-frame pauses.

Abstract: An electronic display may include a touch sensing system configured to perform touch sensing in an active area of the electronic display and display driver circuitry configured to program display pixels of the active area to emit light. The electronic display may also include the active area. The active area may include a first portion and a second portion that are at least partially electrically separated. The display driver circuitry may program the display pixels in the first portion while the touch sensing circuitry may perform touch sensing in the second portion.

Abstract: In an embodiment, an electronic device includes an electronic display. The electronic display provides a programmable latency period in response to receiving a first image frame corresponding to first image frame data. The electronic display also displays the first image frame after the programmable latency period and during display of the first image frame, receives a second image frame corresponding to second image frame data. The electronic display also repeats display of the first image frame in response to receiving the second image frame.

Abstract: The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.

Display driver circuitry may be mounted to the thin-film transistor layer. A display timing controller integrated circuit may be mounted in the base. A rigid flex printed circuit may have a rigid portion in the base to which the display timing controller integrated circuit is mounted and may have a rigid portion in the lid. A flexible printed circuit portion of the rigid flex printed circuit may be used to couple the rigid printed circuit portion in the lid to the thin-film transistor layer. A flexible printed circuit portion of the rigid flex printed circuit that extends between the lid and the base may be formed from a double-shield-layer single-signal-line-layer flexible printed circuit.
