摘要： Apparatus and methods enable robust, reliable control for implantable medical devices, including cardiac pacemakers, defibrillators and cardiac resynchronization devices. Integrated circuits in the devices have minimized interfaces, can derive power from the interface signals, and have high voltage and latch-up protection. A device lead has a power generation circuit and a switching circuit using cascaded PMOS transistors for operating with a stable voltage despite fluctuations in the supplied voltage. The lead has control electronics that provide a very low impedance between an electrode and a lead conductor during most of the duration of a pacing pulse, but during a brief initial portion of the pacing pulse, provide a very high impedance to permit charging up a power supply that is local to the control electronics. A method of stabilizing the external impedance and a system for fault detection and fault recovery for an implantable device are also provided.

摘要： Reducing or eliminating the effects of noise that can be generated by a power system of a touch screen device, such as a gate line voltage system that applies voltage to gate lines of the touch screen, is provided. In one example, a power supply, such as a charge pump, can be disabled during active touch sensing, such that noise from the charge pump is not generated during touch sensing. In some examples, a voltage regulator can help to maintain the gate voltage level at or above a desired threshold. In some cases, noise entering the touch sensing system can have a lasting effect on noise-sensitive components, even after the noise source is disabled. In these cases, a post-noise stabilizing system can be included to stabilize, reset, etc., noise-sensitive components of the touch sensing system, which can help to reduce or eliminate the lasting effect of noise.

摘要： The disclosed embodiments relate to a system that provides power for a touch-enabled display, wherein the touch-enabled display cycles between a display mode and a touch mode. During the display mode, the system drives a display-mode voltage to the touch-enabled display through a power output, wherein the power output is coupled through a display-mode capacitor CD to ground. Next, during a transition from the display mode to the touch mode, the system couples the power output through a touch-mode capacitor CT to ground, wherein CT was previously charged to a touch-mode voltage, which causes the power output to rapidly transition to the touch-mode voltage. Then, during the touch mode, the system drives the touch-mode voltage through the power output.

摘要： Methods and devices useful in compensating for VDD and VTH variations in a micro light-emitting diode (micro-LED) display are provided. By way of example, an LED driver includes a first transistor having a first source coupled to an upper voltage rail (VDD), a first gate, and a first drain. The LED driver includes a second transistor having a second source coupled to the first drain of the first transistor, a second gate, and a second drain coupled to the LED. The second transistor is configured to receive the drive current signal from the first transistor and supply the drive current signal to the LED. The LED driver includes compensation circuitry configured to adjust the drive current signal such that the drive current signal is independent of the upper voltage rail (VDD) and a threshold voltage (VTH) of the first transistor or the second transistor.

摘要： Methods and devices employing circuitry for quickly discharging pixels of a display before the display is turned off are provided. In one example, a method may include receiving at the electronic display a signal indicating the electronic display will be powered off within a period of time. The method may also include, in response to the signal, causing a frame of pixel data originating from the electronic display to be stored in pixels of the electronic display before the electronic display is powered off. Storing the frame of pixel data in the pixels may inhibit image artifacts from occurring on the electronic display when the electronic display is powered back on in the future.

摘要： The present disclosure generally relates to gamma bus wiring techniques that saves space in a display such as a liquid crystal display. In certain embodiments, a voltage offset associated with gamma bus amplifiers configured to provide analog voltage levels to a pixel may reduce at least some of the visual performance characteristics of the attached display when it transitions between different voltage values provided by different gamma bus amplifiers. The voltage offsets associated with the gamma bus amplifiers may be distributed between multiplexers that are coupled to gamma bus amplifiers by interlacing the wires routed from a resistor string to the multiplexers.
