Abstract: A system for radio frequency transmission through a window is provided. The system may include a first wireless coupler, a second wireless coupler, and one or more antennas. The first wireless coupler may be attached to a first side of the window and configured to transmit or receive radio frequency signals. The second wireless coupler attached to a second side of the window and aligned with the first wireless coupler. The first wireless coupler may be configured to transmit or receive the radio frequency signals from the first wireless coupler to the second wireless coupler through the window. The one or more antennas may be electrically connected to the second wireless coupler. One or more radios may transmit or receive the radio frequency signals to or from the one or more antennas.

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.
