  • Publication number: 20150053862
    Abstract: The present invention is thus directed to an automated system of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Moreover, the system utilizes configured wedge shaped windows to best minimize the reflections of light which cause periodic variation in transmission at different wave lengths (commonly described as “channel spectra”). Such a system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

    Abstract: A step sensor for mounting on a ladder having a step. The step sensor adapted to be mounted to the ladder. The step sensor includes a housing that holds a power source and electronic circuitry. An emitter is connected to the electronic circuitry and emits a light source over a top surface of the step. A sensor is also connected to the electronic circuitry and receives reflected light from the light source that is reflected by an object on the step. A noise generator generates an alert noise in response to the reflected light being detected by the light sensor, whereby the presence of an object is detected on the step and the alert is generated by the noise generator. A ladder including such a step sensor.

  • Publication number: 20140183365
    Abstract: The invention relates to an apparatus for monitoring extruded products moving in an inline extrusion process so as to affect quality control of the process by continuously measuring dimensional parameters and determining the existence of contaminants in the extrusion. The apparatus makes use of Terahertz radiation, which is adapted to provide a curtain of parallel rays of the radiation, which is scanned across the product as the product passes there-through in a linear manner. The composition of the omitted radiation received after the scanning process is subject to an imaging analysis to determine the dimensional parameters and contaminant free integrity of the extrusion process.
