    Abstract: To provide sufficient sensitivity, spectral resolution and speed of measurement for field environmental measurements in a portable spectroradiometer, a silicon photodiode receives light: (1) having a bandwidth in the range of between 2 and 15 nm (nanometers) from a pivotable concave holographic diffraction grating within the wavelength range of between 250 and 1150 nm at a scanning rate in the range of 20 to 100 nm per second; (2) having stray light of high intensity and undesired frequencies and the shorter wavelength harmonics of the selected frequency range blocked by filters; and (3) having flux of a least 10 microwatts per square meter of diffuser plate for each nanometer of bandwidth. Automatic electrical zeroing is obtained by blocking all light once at the beginning of each scan, obtaining an electrical drift-related signal and using the drift signal to ad- just the measured signal during the scan. Several different sensing interfaces can be used, including a quartz, light fiber probe having at least a 50% packing density and a cone angle of at least 24 degrees. The data and the programming storage is at least 30K bytes but the instrument uses no more than two watts of power when the instrument is not scanning.

    Abstract: Apparatus and methods may provide for determining a value of chemical parameter. One or more light emitters may be positioned within a housing to emit light through an aperture of the housing. The emitted light may illuminate a color area of a structure that is separable from the housing, such as a test strip, a printed color reference, and so on. A color sensor may be positioned within the housing to capture reflected light and to convert the reflected light to an initial digitized color space that may be usable to determine a color shade of a color area. The reflected light may, for example, be captured independently at least of a dimension (e.g., predetermined size, shape, etc.) of the color area.

    Abstract: An open scattered light smoke detector for detecting smoke may include a light transmitter for emitting light, a light receiver spectrally matched to the light transmitter, and a control unit configured to repeatedly actuate the light transmitter, with a pulsed signal sequence, to emit corresponding light pulses, evaluate temporally a signal sequence received by the light receiver, and output a fire alarm if a received signal strength exceeds a minimum value for the smoke concentration. The control unit may be configured to switch the detector from a normal operating mode into a service mode if a phase angle between an emitted and received signal sequence, as determined on the detector side, increases by a minimum angular value which, in terms of the travel time, corresponds technically to an increase in the optical path length from the light transmitter to the light receiver of more than some predefined distance.

    Abstract: An egg identification system for determining viability of an avian egg is provided. Such a system includes an emitter assembly configured to emit electromagnetic radiation toward an egg. A detector assembly is axially aligned with the emitter assembly to detect electromagnetic radiation transmitted through the egg. The detector assembly is spaced-apart from the egg during operation thereof such that the detector assembly does not contact the egg. The detected electromagnetic radiation is used to generate an output signal. The output signal is processed to determine whether there exists a periodic variation or an aperiodic perturbation in an intensity of the electromagnetic radiation transmitted through the egg corresponding to action of a heart or embryo movement, wherein the existence of the periodic variation or aperiodic perturbation indicates that the egg is viable. An associated method is also provided.
