    Patent number: 9222169
    Abstract: A solar call is provided along with a method for forming a semiconductor nanocrystalline silicon insulating thin-film with a tunable bandgap. The method provides a substrate and introduces a silicon (Si) source gas with at least one of the following source gases: germanium (Ge), oxygen, nitrogen, or carbon into a high density (HD) plasma-enhanced chemical vapor deposition (PECVD) process. A SiOxNyCz thin-film embedded with a nanocrystalline semiconductor material is deposited overlying the substrate, where x, y, z?0, and the semiconductor material is Si, Ge, or a combination of Si and Ge. As a result, a bandgap is formed in the SiOxNyCz thin-film, in the range of about 1.9 to 3.0 electron volts (eV). Typically, the semiconductor nanoparticles have a size in a range of 1 to 20 nm.

  • Noise event suppression for monitoring system
    Patent number: 9208770
    Abstract: A noise event suppression technique for a monitoring system detects a noise event in a signal waveform when a focal sample in the waveform has an amplitude greater than an amplitude of algorithmically determined earlier and later samples in the waveform that are noncontiguous with the focal sample. When the monitoring system detects the noise event, the monitoring system reduces the amplitude of the focal sample to an amplitude between those of the earlier and later samples. The monitoring system outputs data determined using the waveform once noise events have been adequately suppressed.
