    Abstract: A fly-back type switched current regulator includes a primary transformer winding coupled to receive a rectified DC signal derived from an AC signal. The drain of a power transistor is coupled to the primary winding, with the source of the power transistor coupled to an input of a comparison circuit and a primary transformer winding sense resistor. A control terminal of the power transistor is coupled to an output of the comparison circuit. A capacitor stores a variable reference signal for application at a first capacitor terminal to another input of the differential circuit. The variable reference signal is compared to a winding current signal generated by the sense resistor by the comparison circuit. An injection circuit applies an AC signal derived from the rectified DC signal to a second terminal of the capacitor so as to modulate the stored variable reference signal. The regulator is coupled to drive LEDs.

    Abstract: A method of making inkjet print heads may include forming a first wafer including a sacrificial substrate layer, and a first dielectric layer thereon having first openings therein defining inkjet orifices. The method may also include forming a second wafer having inkjet chambers defined thereon, and joining the first and second wafers together so that each inkjet orifice is aligned with a respective inkjet chamber. The method may further include removing the sacrificial substrate layer thereby defining the inkjet print heads.

    Abstract: An embodiment is an integrated System on Chip (SoC) including a communication interface configured to implement a communication protocol including functional blocks that are energized or de-energized individually so that a minimum power consumption is used to receive and detect a signal, and a receiver identification (ID) detection function configured to determine whether the signal is intended for the device in which the SoC resides. The SoC further includes a power management function configured to control which functions in the SoC and/or device in which the SoC resides are energized or de-energized depending on the results of the receiver ID detection function, and a power source capable of energizing a minimum number of the functional blocks required to receive and detect a signal, wherein the power source can be used in a low power state and switched over to a main power supply when the SoC is energized.

    Abstract: A dual-master controller includes a plurality of JTAG data registers including a controller-mode register that stores information indicating a standard JTAG or a processor-controlled mode of operation. A JTAG TAP controller receives control signals over a standard test access port and a processor controller receives processor control signals over an external processor bus. A selection multiplexer outputs either signals on the standard JTAG access port or the external processor bus responsive to a JTAG mode selection signal. A logic circuit activates the JTAG mode selection signal responsive to the force JTAG signal being active or information in the controller-mode register indicating the standard JTAG mode, and deactivates the JTAG mode selection signal responsive to the force JTAG signal being deactivated or the information in the controller-mode register indicating the processor-controller mode. An instruction decoder and multiplexer circuit applies control signals from the selection multiplexer to control the JTAG data registers.
