    摘要： A tissue analyte measuring device (2) includes a light source (4) structured to emit unpolarized light toward the skin surface of a subject, and a detector assembly (8) configured to receive light reflected from the skin surface of the subject and the transcutaneous tissues of the subject, the detector assembly including a polarizing filter (12) and a number of light detector subassemblies (14). The polarizing filter is structured to filter out s-polarized light and pass only p-polarized light to light detector subassemblies. The light source is structured and positioned to emit the unpolarized light in a manner wherein the unpolarized light will exit the measuring device at a predetermined angle with respect to a normal to a light emitting plane of the measuring device, wherein the predetermined angle is an angle (the Brewster's angle) at which only s-polarized light will be reflected by the skin surface when the unpolarized light is incident thereon.

    摘要： An analyte measuring device (5) for monitoring, for example, levels of a tissue analyte (e.g., bilirubin), includes a number of narrow band light sources (10), each narrow band light source being structured to emit a spectrum of light covering a number of wavelengths, and a number of detector assemblies (15) configured to receive light reflected from the transcutaneous tissues of a subject. Each of the detector assemblies includes a filter (20) and a photodetector (25), each filter being structured to transmit a main transmission band and one or more transmission sidebands, wherein for each narrow band light source the spectrum thereof includes one or more wavelengths that fall within the transmission band of at least one of the filters, and wherein for each narrow band light source the spectrum thereof does not include any wavelengths that fall within the one or more transmission sidebands of any of the optical filters.

    摘要： This invention relates generally to a method of recording video information onto an optical disc of the rewritable type. The invention relates to determining in real time whether errors were encountered during recording a physical sector and generating error sector information comprising a list of sectors wherein errors were encountered during recording. The error sector information is recorded on disc, preferably in VRMI user data to playback compatibility with standard players. During playback, error sector are skipped from reading. Advantageously, a buffer cell is created for information recorded in error sectors so that seamless playback is possible. Advantageously, when formatting the disc, the error sector information is not deleted. Advantageously, the error sector information is used to inform the user about the disc quality.

    摘要： A bilirubin measuring apparatus includes a sample holding portion for holding at least a sample to be analyzed, a light source for directing light toward the sample holding portion, and means for determining a concentration of bilirubin in the sample based on an amount which the light is refracted while passing through the sample holding portion when at least the sample is held at the sample holding portion. Also, a method of measuring bilirubin in a sample includes holding at least the sample at a sample holding position, directing light toward the sample holding position so that the light will pass through the sample, and determining a concentration of bilirubin in the sample based on an amount which the light is refracted while passing through the sample holding position.
