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： 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.
