摘要:
A voltage mode transmitter equalizer has high efficiencies, yet consumes substantially constant supply current from the power supply and provides constant back-match impedance. The voltage mode transmitter equalizer is configured such that the output voltage of the signal to be output on a pair of transmission lines can be controlled according to the input data, but its return impedance is substantially matched to the differential impedance of the transmission lines and it draws substantially constant supply current from the power supply regardless of the output voltage of the signal. Further, an equalizer for a voltage-mode transmitter provides fine-granularity equalization settings by employing a variable pull-up conductance and a variable pull-down conductance. Conductance is varied by selectively enabling a plurality of conductance channels, at least some of which have resistance values that are distinct from one another.

First and second inertial sensors are arranged in such a manner that their sensitive axes may be made alternately parallel and anti-parallel to one another. Measurements from both inertial sensors are taken during parallel and anti-parallel periods. Measurements from these two periods are used to calculate sensor biases for both sensors. Sensor biases so obtained are used to correct the outputs of the first and second inertial sensors.

A data system 102 permits bus encoding based on frequency of the bus; an encoding scheme may be implemented to avoid undesirable frequency conditions such as a resonant condition that may lead to degradation in system performance. The device or integrated circuit will typically include an encoder; in one embodiment, the encoder is a data bus inversion (DBI) circuit that selectively inverts all lines of a data bus. A detector that may include a band-pass or stop-band filter that, for example, evaluates data for transmission on the bus to detect frequency, for example, a predetermined frequency or a frequency range. The detector provides a control signal for the encoder to selectively apply an encoding scheme as a function of frequency.
摘要:
A handshower is disclosed providing two different radial spray patterns that can be selectively operated. There is a handle adapted for connection to a water supply, a nozzle head having an outer sleeve and an inner chamber connected to the handle, and an axially extending waterway positioned in an inner chamber of the nozzle head. On the sleeve there is an array of outlets running from the inner chamber to an outer radial face. The waterway has an axially extending channel and multiple sets of radially extending orifices. The sleeve is rotatable relative to the waterway from a first position where the channel is in communication with a first group of outlets to a second position where the channel is in communication with at least some of the outlets that are not in the first group.

Disclosed is a method for inter-antenna baseline determination that uses an antenna configuration comprising a pair of relatively closely spaced antennas and other pairs of distant antennas. The closely spaced pair provides a short baseline having an integer ambiguity that may be searched exhaustively to identify the correct set of integers. This baseline is then used as a priori information to aid the determination of longer baselines that, once determined, may be used for accurate run time attitude determination.
摘要:
A method for reducing the total fat and cholesterol contents and the ratio of saturated to unsaturated fatty acids and for increasing total protein content in eggs produced by animals is described. The level of L-Dihydroxyphenylalanine (L-DOPA) in the bloodstream of the poultry is elevated so as to cause the animals to produce eggs which have a reduced cholesterol content and eggs which have a lower ratio of saturated to unsaturated fatty acids. In a preferred embodiment the L-DOPA is orally administered to poultry by incorporation in the food for said poultry.

This invention relates to methods for regulating or ameliorating lipid metabolism which comprise administration or timed administration of inhibitors of dopamine beta hydroxylase (DBH).
摘要:
Disclosed are methods for improving various aberrant metabolic indices in mammals including humans by administration of muscarinic (particularly M1) receptor antagonists alone or in combination with prolactin inhibiting compounds. Preferably the administration takes place at a predetermined time (or, if a combination of muscarinic receptor antagonist and prolactin inhibitor is used, at different predetermined times) during a 24-hour period when the administration is effective (or its effect more pronounced). The invention has application in the treatment of lipid and glucose metabolism disorders.
摘要:
A method for reducing the total fat and cholesterol contents and the ratio of saturated to unsaturated fatty acids and for increasing total protein content in eggs produced by animals is described. The level of n-Dihydroxyphenylalanine (L-DOPA) in the bloodstream of the poultry is elevated so as to cause the animals to produce eggs which have a reduced cholesterol content and eggs which have a lower ratio of saturated to unsaturated fatty acids. In a preferred embodiment the L-DOPA is orally administered to poultry by incorporation in the food for said poultry.
