Abstract: Systems and methods are provided for authenticating image files when network connections should not or cannot be used to transfer image files. A user device application may capture an image at a user device, generate an image file, and generate a hash file based on the image file. Instead of sending the image file to an authentication server for authentication, the application may send the hash file. If desired, the application may transfer the image file when a desirable network connection is available. Any alteration to the image file in the meantime will result in a different hash file for the altered image file, thus allowing detection of altered image files. This approach offers decreases the amount of data that is required to be transmitted in low or undesirable signal conditions, while maintaining an ability to detect alterations to image files that may have been made in the meantime.

Abstract: A gravity-feed dispenser is connected to a hopper configured to hold a bulk material for dispense. The gravity-feed dispenser includes a spout and a valve separating the hopper from the spout. An actuator assembly is connected to the valve and includes a detectable element. The actuator assembly is operable to move the valve between open and closed conditions to selectively permit bulk material to pass from the hopper out of the spout. A fixture is configured to engage and support the gravity feed dispenser. A sensor is connected to the fixture and is positioned relative to the actuator assembly. The sensor operates to detect the detectable element of the actuator assembly and produce a signal indicative of the open condition or the closed condition.

Abstract: A system for detecting an optical network condition, such as a fiber bend, has an optical line terminal (OLT) that is configured to communicate control information with optical network terminals (ONTs) indicating the transmit power levels and the receive power levels of optical signals, such as optical data signals, that are communicated between the OLT and the ONTs. Based on such information, line losses at different wavelengths are determined and then compared in order to detect an optical network condition, such as a fiber bend. Since the measurements can be performed on optical data signals ordinarily communicated between the OLT and the ONTs, the testing may be performed during data communication. Further, as long as optical communication between the OLT and the ONTs is possible, a fiber bend or other network condition may be detected at any point along the optical path.

Abstract: A method and apparatus for cooling the heat generated by a gas turbine engine mounted in a compartment is provided. The apparatus comprises a novel eductor that incorporates a mixer nozzle to entrain sufficient air flow through the compartment to provide all the necessary cooling. The engine's oil cooler is mounted to the eductor so that the entrained air flow passes through it and cools the engine's oil. The novel eductor also has means for receiving a flow of high velocity air from the engine and injecting this air downstream of the mixer nozzle to enhance the entraining of the cooling flow.

Abstract: A compact turbine engine exhaust gas noise suppressor has a housing having a first chamber, a second chamber having an outlet and communicating with the first chamber through a transfer passage, and a third chamber communicating with the first chamber through a perforated dividing wall and having a resonant sound attenuator positioned therein. A sound absorbing member is positioned in the second chamber to create therein a serpentine flow path extending between the transfer passage and the outlet. The exhaust gas noise is attenuated by flowing the exhaust gas into the first chamber through a duct into which ambient cooling air is educted, and then forcing the exhaust gas outwardly through the serpentine flow path.

Abstract: An axially asymmetric exhaust gas muffler has a perforated central exhaust duct that is circumscribed by a duality of reactive sound attenuating chambers in each of which is positioned a resonant sound attenuator.
