Abstract: A handgun sear has a sear body extending between a proximal end portion to a distal end portion. The sear defines a first engagement surface adjacent the proximal end portion and a second engagement surface positioned distally of the first engagement surface. The sear can pivot about the distal end portion between a cocked position and a displaced position. The second engagement surface can be used to arrest forward movement of the striker in the event of an impulse that causes the striker to disengage from the first engagement surface. The sear may be incorporated into a fire control assembly of a semiautomatic handgun or other firearm.

Abstract: A tamper-resistant containment package is described, including a container; a cover configured to engage with the container so that the container and cover form an enclosed volume; and at least one tamper-resistant mechanical fastener that is cooperative with the cover and container to render the containment package tamper-resistant when the container and cover are engaged in a sealed state isolating the enclosed volume from an ambient environment surrounding the containment package. Such containment package is usefully employed for storage and transport of chemical reagents that pose a health, safety, and/or environmental risk if released to an exterior environment of the containment package.

Abstract: An apparatus for protecting sensitive electronics in a downhole tool from mechanical shock and vibration. The apparatus includes a frustum-shaped sleeve configured to be disposed between the downhole tool and another downhole component through which a mechanical shock may travel to the downhole tool. The mechanical shocks may result in axial, radial, and/or rotations stress on the downhole tool. The frustum-shaped sleeve is disposed on one part of an interconnection pair made of a mating plug and a mating receptacle.

The gas cell defines an optical volume for travel of the light beam within the gas cell, and the optical volume comprises at least a portion of the overall volume and is configured to suppress turbulent flow of the gas mixture within the optical volume to reduce optical noise generated by the gas mixture.

Abstract: A technique for the detection of an unauthorized wireless communication device includes monitoring of Bluetooth® communications activity by a Bluetooth® capable communication device. Any monitored communication activity is analyzed against parameters that are predefined to detect suspected illegal activity. If illegal activity is suspected by the analysis, an alert is generated for a system administrator. The predefined parameters associate illegal activity with; data that includes credit card numbers and expiration dates, credit card transaction logging information, non-discoverable devices, activity after store hours, exceedingly long activity, etc.

The hub crane assembly includes an adjustable articulating arm mountable at a first height on a hub of the wind turbine at a hinge point, a first hoist mountable at a second height of the wind turbine, the second height being greater than the first height, and a support component secured to the first hoist and a first attachment point of the articulating arm. Further, the first hoist is configured to rotate the articulating arm about the hinge point via the support component such that, as the articulating arm rotates, a clearance distance between the wind turbine and the articulating arm changes.

Abstract: A gaming system including a central server linked to a plurality of gaming devices. The central server tracks the occurrences of one or more suitable events occurring at or in association with one or more gaming devices in the gaming system. Upon the central server determining that the quantity of occurred events tracked has reached a designated quantity or threshold, (i.e., a triggering event has occurred), the gaming system provides a progressive award to one of the players at one of the gaming devices in the gaming system.

Abstract: A technique for locating a wireless communication attack includes monitoring of Bluetooth® communications activity by a Bluetooth® capable communication device. Any monitored communication activity is analyzed against parameters that are predefined to detect a communication attempt by a suspected criminal device to an illicit device. If the communication attempt by the suspected criminal device is detected by the analysis, a communication to the criminal device is controlled so as to delay completion of the communication to the criminal device in order to provide time to locate the criminal device.

Abstract: Apparatus and method for coverage hole detection in a wireless local area network (WLAN) using a mobile communication device. The method includes a first step of providing a plurality of access points distributed within the WLAN and at least one mobile communication device operable within the WLAN. A next step includes downloading triggers for respective coverage measurement conditions to the at least one associated mobile communication device from an associated access point. A next step includes detecting a coverage measurement condition by the at least one mobile communication device that activates one of the triggers, whereupon a next step includes sending a coverage measurement indicating the triggered condition from the at least one mobile communication device to an associated access point, which forwards a coverage incident report to a Central Report Manager.

Abstract: A system for the removal of nitrogen from a liquid natural gas (LNG) stream. The system. comprises a feed heat changer and a stripper column. The heat receives the LNG stream and cools the LNG stream via heat exchange with a stripper column side-draw stream to yield a cooled LNG stream and a heated side-draw stream. The stripper column receives the cooled LNG stream at a first tray and the heated side-draw stream. The stripper column produces the stripper column side-draw stream, a stripper column overhead stream, and a stripper column bottom stream. The stripper column side-draw stream is taken from the stripper column at a second tray. The second tray is at least about 15 feet higher than the feed heat exchanger.
