Patent number: 9908158Abstract: This invention provides a mechanism for clearing debris and vapors from the region around the optical axis of a vision system that employs a directed airflow in the region. The airflow is guided by an air knife that surrounds a viewing gap placed in front of the camera optics. The air knife delivers airflow in a manner that takes advantage of the Coanda effect to generate an airflow that prevents infiltration of debris and contaminants into the optical path. Illustratively, the air knife defines a geometry that effectively multiplies the delivered airflow approximately fifty times (twenty-five times on each of two air-knife sides) that of the supplied compressed air. This provides an extremely strong air curtain along the scan direction that essentially blocks infiltration of environmental contamination to the optics of the camera.Type: GrantFiled: March 10, 2014Date of Patent: March 6, 2018Assignee: AMETEK, INC.Inventor: Volker Koelmel

Publication number: 20140049274Abstract: An apparatus and system for measuring levels of two or more materials maintained within a storage tank using a combination of both a capacitance sensor and a time domain reflectometry (“TDR”) waveguide sensor is disclosed. The apparatus includes a combined circuit for the capacitance sensor and TDR sensor that creates a separation between the return signal from the capacitance sensor and the TDR sensor. The need for the return signal separation is due to the generation of false reflection signals from the capacitance circuitry. In a preferred embodiment, the separation in time is created by moving the capacitance false reflections further in time than the true signal returns. An alternative preferred embodiment would delay the true TDR signals passed the capacitance false reflections. Another alternative preferred embodiment would provide a substantially matched impedance of the capacitance circuit to the TDR circuit, to substantially eliminate the false reflections.Type: ApplicationFiled: April 30, 2012Publication date: February 20, 2014Applicant: AMETEK, INC.Inventor: Kevin G.
