  • Patent number: 11515428
    Abstract: One example provides an integrated circuit comprising a transistor including a semiconductor channel. The semiconductor channel includes three or more sub-channels, one or more nodes, each node being a junction of at least three sub-channels, and channel ends. A Schottky contact at each channel end forms a source or drain contact, and a gate contact disposed at each Schottky contact controls a barrier conductivity of the corresponding Schottky contact.

  • Patent number: 10092200
    Abstract: A plethysmograph variability processor inputs a plethysmograph waveform having pulses corresponding to pulsatile blood flow within a tissue site. The processor derives plethysmograph values based upon selected plethysmograph features, determines variability values, and calculates a plethysmograph variability parameter. The variability values indicate the variability of the plethysmograph features. The plethysmograph variability parameter is representative of the variability values and provides a useful indication of various physiological conditions and the efficacy of treatment for those conditions.

  • Patent number: 7797708
    Abstract: Methods and apparatus, including computer program products, are provided for simulating business object behavior with a mockup object. In one exemplary embodiment, the method may include receiving a name of the mockup object for which to perform a specified action on, wherein the mockup object comprises one or more nodes, and receiving the action to be performed on the mockup object. The method may also include determining whether the action can be performed on the mockup object based on a set of conditions defining the status of the mockup object, and performing the action based on the determining step.

  • Publication number: 20080045810
    Abstract: A transform for determining a physiological measurement is disclosed. The transform determines a basis function index from a physiological signal obtained through a physiological sensor. A basis function waveform is generated based on basis function index. The basis function waveform is then used to determine an optimized basis function waveform. The optimized basis function waveform is used to calculate a physiological measurement.

  • Publication number: 20080033265
    Abstract: A method and an apparatus measure blood oxygenation in a subject. A light source is activated to cause a first emission at a first wavelength and a second emission at a second wavelength. A detector detects a composite signal indicative of an attenuation of the first and second wavelengths by tissue of a patient. The composite signal is demodulated into a first intensity signal and a second intensity signal. Blood oxygenation in the subject is determined from the first and second intensity signals. In one embodiment, demodulation is based at least in part on a period when at least one of the wavelengths is not activated. In one embodiment, a modulation of the first and second wavelengths is determined in order to avoid frequencies of ambient noise. In one embodiment, the composite signal's sampling rate is reduced before and/or after demodulation.

  • Publication number: 20070073127
    Abstract: A monitor has an optical input from which a spectral characteristic can be derived. The monitor also has a non-optical input from which a parameter can be determined. A compensation relationship is determined for the spectral characteristic based on the parameter. A physiological measurement is determined based on the spectral characteristic and the compensation relationship.
