20130073242 | SMALL VOLUME PROVER APPARATUS AND METHOD FOR MEASURING FLOW RATE - A small volume prover apparatus and method for precisely measuring the flow rate of a fluid via a cylindrical component such as a flow tube. A precision bore cylinder and a piston can be configured with a valve arrangement in order to permit fluid to pass through an annular passage when the piston travels from one position to an opposite position. An accelerometer sensor can be mounted to the piston for continuously detecting the velocity of the piston traveling in the pipe by integrating acceleration data with respect to time data. The volumetric flow rate can be automatically calculated by multiplying the velocity with respect to the area of the flow tube. | 03-21-2013 |

20130218022 | Personal Protective Equipment with Integrated Physiological Monitoring - Embodiments may comprise personal protective equipment with integrated physiological monitoring. Some embodiments may relate specifically to in-ear devices (such as hearing protection and/or communication devices) having one or more physiological sensors for early monitoring for heat related illnesses. Several embodiments may incorporate a temperature sensor and a speaker into such in-ear device. | 08-22-2013 |
20130228692 | FLAME DETECTOR WITH OPTICS ARRAY - A system includes a micro-optic array of pixel elements positioned to receive radiation from a flame. A mid-wave infrared (MWIR) detector is positioned to receive mid-wave infrared radiation from the micro-optic array. A filter is provided to pass mid-wave infrared radiation to the MWIR detector. A controller is provided to sequentially select different sets of pixel elements of the micro-optic array to provide mid-wave infrared radiation to the MWIR detector representative of the flame. | 09-05-2013 |
20130234028 | METHOD AND DEVICE FOR DETECTION OF MULTIPLE FLAME TYPES - A flame detector includes an infrared detector and a first window covering the infrared detector. A second window is positioned in front of the first window. The flame detector is adapted to reject light having a wavelength below approximately 2 μm and to reject light having a wavelength above approximately 6 μm, allowing detection of flame from multiple sources. In variations, the windows in combination with the infrared detector may provide the rejection or a band pass filter provides the rejection. Still further variations utilize notch filters or a band reject filter to provide notches of light to the infrared detector corresponding to the wavelength of different flame sources to be detected. | 09-12-2013 |

20140311211 | GAS SENSING DRIFT COMPENSATION USING GAS SELF-REFERENCING FOR END OF SERVICE LIFE INDICATION FOR RESPIRATORS - Embodiments relate generally to systems and methods for determining end of service life for a respirator cartridge by comparing the gas levels sensed at two or more sample points within the cartridge. Sample streams may run from the sample points to a gas sensor, wherein a valve may control the flow between the sample streams and the gas sensor. | 10-23-2014 |
