Abstract: A method for operating a vehicle charging system includes providing data from an electric vehicle through a wireless communications device removably installed in the electric vehicle. The method also includes wirelessly receiving the data by an electric vehicle charger. Additionally, the method involves managing, by the electric vehicle charger and using the data, provision of charging current from the electric vehicle charger for traction batteries of the electric vehicle.

Abstract: A CMOS transmission gate that is compensated for lost current to parasitic capacitance. Parasitic capacitance current is detected by an amplifier and fed back in-phase to the input of the CMOS transmission gate with the gain of the amplifier set to avoid circuit instability. In a first example a transconductance amplifier detects a voltage drop across a resistor in and RC network and the resulting current applied to the input of the transmission gate. A second example uses a current amplifier to detect gate current of the N-channel and P-channel transistors of the transmission gate, and an output current is fed back in phase to the input of the CMOS transmission gate.

Abstract: Methods and circuits for CMOS relaxation oscillators are disclosed. A single capacitive element, a single current source and a switching network are utilized. A switching network of the oscillator allows both nodes of the capacitive element to rise and fall between a positive and a negative voltage with respect to ground supply, without causing leakage to substrate or risk of latch-up, i.e. the inadvertent creation of a low-impedance path. The oscillator requires minimum silicon area, has an improved duty cycle, is particular useful for implementing lower frequency clocks and is enabled for smaller technology nodes, lower than 250 nm, due to lower supply voltage.

Abstract: Systems, methods, and computer-program products identify clinical data corresponding to a plurality of patients located within a common health care delivery unit, and apply one or more rules to at least some of the clinical data using at least one quality and/or safety measure-specific specification. Based on the application of the rules, one or more care indicators corresponding to the plurality of patients are displayed in a single interface, the one or more care indicators indicating whether one or more of the patients is receiving appropriate care.
