  • Patent number: 9754646
    Abstract: Embodiments relate to circuits, electronic design automation (EDA) circuit layouts, systems, methods, and computer readable media to enable logic devices operating on a core supply voltage to drive memory devices operating on a different supply voltage using low power and high data rates while avoiding voltage over-stress of thin-oxide transistors. In an embodiment, channels of a thin-oxide PMOS transistor, a thick-oxide PMOS transistor, a thick-oxide NMOS transistor, and a thin-oxide NMOS transistor are coupled in order from a memory device voltage supply rail to a low voltage supply rail. Gates of the thin-oxide PMOS transistor and the thick-oxide NMOS transistor are coupled with an output of a flying capacitor circuit that level-shifts an input signal by a difference between the memory device supply and core supply voltages, while gates of the thick-oxide PMOS transistor and the thin-oxide NMOS transistor receive the input signal via a buffer.

  • Publication number: 20170246408
    Abstract: A method of acclimatizing a user to provide continuous positive airway pressure (CPAP) therapy, including operating a device for treating sleep disordered breathing (SDB) during successive treatment sessions, wherein the device provides continuous positive airway pressure during sleep, includes determining a clinically-derived full therapeutic pressure, applying a sub-therapeutic treatment pressure for the duration of a first session, obtaining responses to a series of pre-programmed patient and/or bed partner feedback questions before the start of a second session, and, based on the responses, either incrementally increasing the treatment pressure for the second session if the responses indicate that the patient is adjusting to therapy, or maintaining the treatment pressure for the second session if the responses do not indicate that the patient is adjusting to therapy.
