Abstract: In an implementation of multiple integrated circuit control, a multiple integrated circuit controller initiates and controls data transactions between the multiple integrated circuit controller and integrated circuits. A data link communicates the data transactions between the multiple integrated circuit controller and the integrated circuits, and a clock signal link communicates a clock signal generated by the multiple integrated circuit controller to the integrated circuits. The multiple integrated circuit controller includes a first push-pull driver to drive the data transactions on the data link and includes a second push-pull driver to drive the clock signal on the clock signal link.

Abstract: Embodiments of methods, apparatuses, devices and systems associated with a power management system are disclosed. In one such embodiment, a power management system includes a state machine, capable of transitioning the power management system to a safe state when an input signal and/or an output signal from a component of the power management system indicates occurrence of an error in the component.

Abstract: In an implementation, a selectable integrated circuit interface includes selectable integrated circuit interface configurations that can each interface an integrated circuit. A selection circuit generates a selection signal to select an individual selectable integrated circuit interface configuration, and logic couples a clock signal and data to a selected integrated circuit interface configuration.

Abstract: A method of an embodiment of the invention is disclosed that comprises detecting a turn-off event for an device. The device has an on mode, a sleep mode in which the device consumes less power than in the on mode, and an off mode in which the device consumes less power than in the sleep mode. In response to detecting the turn-off event, the method causes the device to enter the turn-off mode, by turning off power to all components of the device except to one or more components thereof that monitor detection of a turn-on event to cause the device to subsequently exit the off mode.

Abstract: A resonant mode energy recovery circuit is disclosed for supplying drive pulses to an electroluminescent (EL) display arranged as a matrix of pixels addressed by a plurality of column and row electrodes. An external inductor is used to alternately store and supply energy from the column electrodes of the EL display which has an impedance equivalent to an array of capacitors and resistors. Switching transistors and diodes are used to start and stop the resonant current flow at 1/4 wavelength intervals of the resonant frequency of the resonant tank formed by the external inductor and the array capacitors coupled to the column electrodes in order to form the pulses required to address the columns of the matrix. Switched current sources are used to start and stop nonresonant current flow to form the refresh and write pulses used to form the pulses required to address the rows of the matrix.

Abstract: An apparatus for essentially eliminating variations in luminescence (i.e., inverse shadowing) in an electroluminescent (EL) display is disclosed. The pixels of an EL display are driven to their light emitting voltage with a signal having a rise time dv/dt at and above the pixel light emitting threshold voltage which is independent of the number of pixels ON in each display row. The result is that each ON pixel in the display exhibits substantially the same luminescence.
