Abstract: A snow burial survival mask has an exhaust tube connected to a headgear. An intake port of the exhaust tube is positioned adjacent to a breathing portion of the headgear in order to intake exhaled carbon dioxide (CO2)-rich air. An air pump connected to the exhaust tube pump the exhaled air from the intake port to an exhaust port away from the user's face, extending survival time in a snow burial situation. At least one burial detection sensor such as a motion sensor, light sensor and/or CO2 sensor is configured to activate the air pump based on detection of a burial event.

Abstract: A plurality of single-phase synchronizing converter automatically synchronize on a peer-to-peer basis. Each synchronizing converter is configured as a DC-to-DC converter. The synchronizing converters operate in parallel as a multi-phase converter. A common bus between the synchronizing converters includes a sync line and a common phase control line. Proper phasing automatically occurs when power is applied, and the phasing changes automatically as converters are added or removed. When the system powers up, the converters arbitrate for phase position. The phasing positions are random, but the phasing is relatively symmetrical regardless of the number of phases. Preferably, a hot-swappable converter module can be plugged into any location of a parallel multiphase bus to produce a common output voltage. When an additional module is plugged in, the converters readjust their phases to maintain phase symmetry. Preferably, each module shares a substantially equal portion of the output load.

Abstract: A telephone line interface or data access arrangement (DAA) is provided which draws power for the customer premises equipment from the telephone line. The DAA includes a shunt regulator as the power source drawing power from the telephone line, and a line modulator in series with the shunt regulator. A sense resistor is placed in series between the line modulator and shunt regulator to sense the line current. Accordingly, DC termination and AC modulation characteristics as presented by the DM to the telephone line can be adjusted by variation of an AC signal with DC offset input to the amplifier driving the line modulator without requiring a different DAA for use in regions or countries having various DC termination and AC modulation requirements. The differential feedback from a sense resistor reduces the noise induced in the circuit from the shunt regulator.

Abstract: A method and apparatus for controlling the DC line current on a telephone line and reducing the amount of error introduced to the system. The error is reduced by compensating for a DC error term introduced by an analog to digital converter having a DC offset. The DC offset is controlled digitally, allowing software to be used to limit the DC error in accordance with predefined parameters. Predefined parameters can be set to accommodate varying country specifications instead of using switches to control resistors and capacitors. In addition, changes in a country's requirements can be accomplished through software, instead of changing components or redesigning a circuit board. The use of software results in increased flexibility by allowing an infinite number of settings via software or software updates, allowing changes to be made quickly and easily throughout the world, and allowing error terms to be accommodated digitally.

Abstract: A telephone line interface or data access arrangement (DAA) includes a shunt regulator in series with a line modulator. A sense resistor is placed in series between the shunt regulator and line modulator to provide a measurement of an amount of noise in the DAA shunt regulator, which is fed back to the line modulator. The line modulator is capable of adjusting the AC modulation and DC termination presented to the telephone line. The method includes drawing power from the telephone line using a shunt regulator, modulating the telephone line in series with the shunt regulator, sensing a level of noise in the shunt regulator, and feeding back the sensed level of noise to the line modulator.

Abstract: A network interface circuit employing differentially driven capacitive couplings across a high voltage isolation boundary and in which a &Sgr;/&Dgr; CODEC is positioned on the line side of the high voltage interface. In this manner, only four wires cross the high voltage boundary, namely differential pairs for transmit data and receive data. The transfer functions for setting AC and DC parameters, such as impedance matching, are provided by digital filters. Further, with the CODEC on the line side of the high voltage isolation interface, the data which crosses the interface is modulated at the &Sgr;/&Dgr; data rate and, thus, capacitive coupling can be used across the high voltage isolation boundary without the loss of DC data.

Abstract: The number of separate signals necessary in a serial interface are reduced by combining a transmit data signal with a clock signal having a rate equal to a multiple of a bit rate of the transmit data signal, before encoding for transmission. The number of separate signals in a serial interface may be reduced further by sigma-delta (&Sgr;/&Dgr;) encoding the transmit data into 1-bit samples, thus eliminating the need for a frame sync signal. By combining the transmit data with a higher rate clock signal, jitter in the recovered clock signal at the receiving end is greatly reduced or even eliminated. At the receiving end, the higher speed clock is recovered at the multiplied rate, used to latch the transmit data from the combined data and higher clock signal, and divided back to the data rate to provide an original bit clock along with an original transmit data signal.

Abstract: A method and apparatus to receive and demodulate call related information, e.g., Caller ID information, in an audio codec placed on the line side and powered by current drawn from the telephone line. The audio codec includes a 1st order &Sgr;/&Dgr; A/D converter to digitize the signal from the telephone line with &Sgr;/&Dgr; modulation. The 1st order &Sgr;/&Dgr; A/D converter may be a scaleable component capable of alternative operation in a 2nd order. The &Sgr;/&Dgr; encoded digitized signal is digitally processed by a DSP including an amplifier module, a digital filter, a limit/slice module, and an FSK decoder to receive and output the call related information. Placement of the audio codec on the line side and the scaleable &Sgr;/&Dgr; A/D converter provides significantly reduced power requirements for the audio codec, thus allowing operation from power derived from the telephone line.
