Abstract: A system for attaching and/or aligning a handguard on a firearm is provided. The system may include a handguard. The system may also include a barrel nut having driven splines and a gear arranged on the handguard with drive splines that mesh with the drive splines of the barrel nut, wherein rotation of the gear draws the handguard toward an upper receiver of the firearm. The system may also include a pair of alignment fingers projecting rearwardly, each from a respective first and second wedge part, toward and along sides of the upper receiver, and the alignment fingers are adjustable to clamp onto the sides of the upper receiver to prevent relative rotation between the handguard and the upper receiver and thereby maintain rotational orientation of the handguard relative to the upper receiver.

Abstract: A lubricant filtration assembly is provided for quick attachment with a lubricant reservoir, for pre-filtering lubricant and pumping the lubricant to its intended destination.

Abstract: A sight gauge assembly for displaying a fluid level of an object includes a first connection member comprising a tap defining a bore therethrough and a body comprising a first passageway and a second passageway such that the first passageway fluidly connects to the second passageway and the bore through an interior of the body and the second passageway to fluidly communicates with the first bore and a first accessory. The sight gauge assembly also includes a second connection member comprising a tap defining a bore therethrough and a body comprising a first passageway and a sight tube defining a hollow interior. The sight tube couples to the first connection member and the second connection member to define a first flow path.

Abstract: An adjustable fluid level verification device and method for use on equipment and containers. The device is connected to bung receivers or mounting holes on the equipment or container, and the device is adjustable to enable mounting on bung receivers that are misaligned or set at an out-of-standard distance.

Abstract: An illumination device comprises a housing, a power supply and at least one light source powered by the power supply. The at least one light source is adapted to emit radiation from the housing at one or more therapeutic wavelengths. The illumination device is positioned in proximity to an area for applying radiation to the area for a time and intensity sufficient to have a bacteriocidal effect.

Abstract: An earbud headset, a handset including the same, and methods of operating the headset and handset are provided. In one embodiment, an earbud headset includes a speaker portion that is retractable into and extendable from a base portion, thereby allowing for a thin profile form factor. Advantageously, the earbud headset allows for more convenient storage and/or integration with a handset such that a user may carry the handset and headset much like a single item.

Abstract: A tool for use in a lubrication system having an oil-containing sump for supplying lubricating oil to a mechanical device and an oiler device connected to the sump for delivering a supply of oil to the sump, the oiler device comprising a base for supporting an oil reservoir and an adjustable element movably disposed within the base for predetermining a level of oil to be maintained within the sump. The tool has a first portion configured to extend into the base for engagement with the adjustable element and a second portion disposed exteriorly of the base to visually indicate the disposition of the adjustable element relative to the oil-containing sump, preferably in the form of a pointing device, optimally a laser beam generating instrument, for representing the disposition of the adjustable element.

Abstract: A portable lubricant filtration system and method is provided for facile pre-filtering of used or new lubricant prior to pumping the lubricant into its intended machinery.

Abstract: A headset having an integrated boom clip for attaching the headset to an object. The headset includes a bottom enclosure, a hinge system coupled to the bottom enclosure, and a boom coupled to the hinge system. The bottom enclosure, boom and hinge system are configured so that the boom can be selectively positioned relative to the bottom enclosure in a closed position or in an open position. In the closed position the boom can be used to clip the headset to an object such as, for example, the user's clothing.

Abstract: A multimode home telephone system includes a computer, a base unit, a wireless handset and a wireless headset. The computer is programmed with a “soft phone” program to make and receive VOIP calls via the Internet and couple them to and from the base through a USB connection. The base is also coupled to a public switched telephone network (PSTN) and is operable to effect full duplex communication via both the PSTN and the Internet. The base, in turn, is wirelessly coupled to the handset via the DECT/UPCS protocol, and the handset is wirelessly coupled to the headset via the Bluetooth protocol, such that the user can selectively place and receive telephone calls via any one of the Internet, the PSTN or an optional Bluetooth enabled cell phone. Optionally, a DECT/UPCS enabled headset can communicate directly with the base in addition to or in lieu of the Bluetooth enabled headset.

Abstract: Systems and methods for a charging station are disclosed. The system generally includes a housing with pockets for receiving a wireless headset and providing charging power from the charging station to the wireless headset. The charging station allows for easy docking and allows the headset to occupy a minimum footprint.

Abstract: Wireless systems having a plurality of physically and electrically-separated data sinks. An exemplary wireless system includes first and second data sinks having no physical or electrical connection therebetween. The first and second data sinks each include a wireless communication device, e.g., a radio frequency (RF) receiver or transceiver configured to receive data signals over one or more single-access wireless links or over a multi-access wireless link. The first and second data sinks in exemplary embodiments may comprise audio data sinks, e.g., stereo speakers, left-ear and right-ear earphones (e.g., earbuds or canalphones), left-ear and right-ear circum-aural over-the-ear headphones, etc. At least one of the first and second data sinks may also be coupled to a wireless transmitter and accompanying data source (e.g., a microphone or sensor), so as to provide, for example, two-way communications between a user and an external data device (e.g., a cellular telephone).
