Abstract: A new and improved intrinsically safe barrier (“ISB”) provides advantages in connection with installation of field equipment in hazardous areas including Division 2/Zone 2 areas. In one embodiment the new ISB provides a pluggable/unpluggable ISB for use with a receiving terminal base adapted for individual field mounting and alternatively for use with a circuit mount terminal base to permit direct mounting of ISB on circuit boards. A highly effective heat sink design and potting material allows for heat dissipation to allow the ISB to serve a wider range of applications.

Abstract: An attack tree model for an aviation system comprises a plurality of tree nodes organized as a tree. For each tree node of the attack tree model model, the tree node corresponds to a respective event that may befall aviation system. An analysis computing system generates one or more attack tree models for the aviation system, wherein the aviation system includes one or more systems, sub-systems, or components. The analysis computing system further performs an assessment of one or more of the system, sub-systems, or components of the aviation system using the one or more attack tree models, and outputs metrics indicative of the assessment.

Abstract: Provided herein are systems that enable proportional air flow delivery control for an air compressor. One system includes a pneumatic air compression system having a flow control member and being adapted to receive inlet air and to compress the inlet air to produce compressed air. The system also includes a pneumatic flow control system including a proportional control valve having a proportionally variable activation state. Varying the activation state of the proportional control valve regulates a pressure acting on the flow control member to regulate the flow of the compressed air produced by the pneumatic air compression system in a variable manner, and further regulates a power demand placed on the engine by the pneumatic air compression system in a variable manner.

Abstract: Responsive to receipt of a first instant message during a first mode operation of an instant messaging program while a computer is driving an exposed output device, the first instant message is blocked. Responsive to receipt of a second instant message during a second mode operation while the computer is driving the exposed output device, an identification of a sender of the second instant message is displayed and a query is issued to determine whether instant message content should be displayed on the exposed output device. Responsive to receipt of a third instant message during a third mode operation while the computer is driving the exposed output device, it is determined that a sender of the third instant message is on a priority list, an identification of the sender is displayed, and a query is issued to determine whether instant message content should be displayed on the exposed output device.

Abstract: A determination is made as to whether a computer is in a slide presentation mode. In response to determining that the computer is in the slide presentation mode, a configured designee alert mode is automatically selected. Message data is received through a communications medium. The message data is transferred to an alternate designated recipient according to the automatically selected designee alert mode when the computer is in the slide presentation mode.

Abstract: A hazardous area coupler is provided which uses arrays of diodes to permit low voltage alternating current signals to pass through while shunting to ground any voltages greater than the clamping voltage of the diodes.

Abstract: An integrated welding system is described that includes an engine-driven power supply, control circuitry for regulating power from the power supply and for delivering power suitable for welding, and a wire feeder driven by the generated power for delivering a continuous feed of wire electrode. The system is suitable for MIG and flux core welding applications, and may further include an optional gas supply for a shielding gas. Other power is available in the system, such as for running conventional 120V and 240V power tools, lights and so forth. The unit may also be operated from an external power source, typically the power grid. The unit may be designed to permit selective operation in accordance with constant voltage and constant current regimes for MIG, TIG and stick welding.

Abstract: A switch having a spring-biased actuator button that moves in an axial direction is mounted in a hermetically sealed cavity defined in a one-piece housing, which also houses a tripping magnet and restricts the tripping magnet to linear movement along the axis of the actuator button.

Abstract: A system and method of controlling a portable radio may involve tuning a first receiver of the portable radio to a first broadcast from a first station, where the first broadcast includes specific program content. A switching event can be detected at the portable radio, where a second receiver of the portable radio may be tuned to a second broadcast from a second station in response to the switching event. The second broadcast can include the specific program content.

Abstract: Illustrative embodiments provide a computer implemented method, an apparatus in the form of a data processing system and a computer program product for social network based call management. In one illustrative embodiment, the computer implemented method comprises receiving an incoming call from a caller for a subscriber, and obtains preferences for the subscriber, wherein the preferences describe a caller relationship to the subscriber. Using a location provided in the preferences for the subscriber, the computer implemented method locates attributes for the caller. The computer implemented method processes the call in accordance with the attributes and the preferences.

Abstract: A rotary valve position indicator utilizes a magnet keyed to a shaft, and a magnetic field sensor mounted beside the magnet, to indicate the angular position of the shaft. A magnetic pole sensor detects the initial polarity of the magnet during setup to determine how to correlate the output readings of the magnetic field sensor with the position of the valve. The sensors are located so they permit the shaft to extend through to a mechanical visual indicator.

Abstract: In certain embodiments, a service pack includes an engine, a tandem pump system coupled to the engine, and a controller. The tandem pump system may include a first pump and a second pump in tandem with one another. The controller may be configured to enable the first pump at a first load condition associated with the engine, the second pump at a second load condition associated with the engine, and both the first and second pumps at a third load condition associated with the engine. The load conditions may correspond to engine loads, hydraulic loads, or other loads associated with the engine. For example, at a low hydraulic pressure, the controller may selectively operate both the first and second pumps, whereas the controller may selectively operate only the first pump or the second pump at high and medium hydraulic pressures, respectively. In this manner, the system can provide suitable flow without overloading the engine.

Abstract: A solution for visual credential verification. The solution includes an apparatus, system, and method embodiment. The apparatus for visual credential verification includes an input module, a comparison module, and a response module. The input module receives from a security official an image of an unverified credential, such as a badge, that an individual has presented to the security official. The comparison module determines whether or not the unverified credential is valid or invalid. The determination includes comparing the image of the unverified credential with known good images of valid credentials. The comparison module may also compare authentication information such as a photo of the individual, a name, or a badge number, with known good authentication information. Based on the comparison module's determination, the response module notifies the security official that the unverified credential is either valid or invalid.
