摘要:
An automatic rifle bolt carrier with a fluted boss for the AR15/M16 family of firearms has been provided. The rear of the bolt carrier has been provided with a boss having bearing surfaces which are in operational contact with the interior of the host firearm's upper receiver to prevent the carrier from tilting while it is reciprocating during normal operation. The boss and rearward end of the bolt carrier are provided with flutes which allow water to flow between the buffer tube and upper receiver while the bolt carrier is reciprocating during normal operation, enabling a properly equipped firearm to be used during over the beach operations. The bolt carrier also includes a scallop cut located about the top of its backmost end which is perpendicular to the longitudinal axis of the bolt carrier.

摘要:
A pressure reduction system may include an alternator with a casing and a rotor positioned, at least in part, within a cavity defined by the casing. The pressure reduction system may also include a mass management system that includes a control tank configured to be maintained at a tank pressure lower than a cavity pressure within the cavity of the alternator, thereby forming a pressure differential. A first transfer conduit may transfer a working fluid from the cavity of the alternator to the control tank via the pressure differential. The mass management system may be positioned at an elevation above the alternator, and include a refrigeration loop configured to cool the working fluid contained within the control tank. A second transfer conduit may fluidly couple the alternator and the mass management system, and may transfer the cooled working fluid from the control tank to the cavity via gravitational force.

A gauge profile apparatus (100) includes a gauge profile system (104) and a lap count system (106) for determining an average three-dimensional profile over the length of a sheet coil (10). The gauge profile system (104) includes a lap profile measuring device (112) which will make a distance determination between top and bottom surfaces for the sheet coil (10). A second embodiment of a lap count system (600) is also provided, which utilizes a pair of reflectance lasers and a positioning system.

摘要:
Apparatus and methods enhancing radio programming include receiving a broadcast radio transmission at a communication device. The broadcast radio transmission includes primary content and supplemental content having a relationship to the primary content. Further, the primary content includes a first audio data, while the supplemental content includes audio data. Additionally, the apparatus and methods include converting the supplemental content into converted supplemental content, maintaining the relationship to the primary content. Moreover, the converted supplemental content includes second audio data converted from the non-audio data. Thus, the described apparatus and methods allow the communication device to output signals for generating audible representations of both the primary content and the supplemental content.

Devices and methods of generating an alert comprise receiving a broadcast radio transmission at a communication device, wherein the broadcast radio transmission comprises primary content and supplemental content having a relationship to the primary content. Further, the primary content comprises a first audio data, and the supplemental content comprises a non-audio data. The devices and methods further include detecting the receiving of the supplemental content, and generating an alert signal operable to activate an alerting device to output a non-visual notification.
