Abstract: A cleaning apparatus includes a combing unit including a series of spaced protrusions or teeth extending into a cleaning roller for preventing build up and removing debris (such as hair, string, and the like). The protrusions extend along a substantial portion of the cleaning roller and extend partially into the cleaning roller to intercept the debris as it passes around the roller. The protrusions have angled leading edges that are not aligned with a rotation center of the cleaning roller and are directed into or against a direction of rotation of the cleaning roller. The combing unit and protrusions have a shape and configuration designed to facilitate debris removal from the cleaning roller with minimal impact on the operation of the cleaning apparatus. The cleaning apparatus may include a surface cleaning head of an upright vacuum cleaner or sweeper or a robotic vacuum cleaner.

Abstract: A conveyor chain includes a plurality of side link assemblies and flight arm assemblies coupled together to form an elongated chain. The flight arm assemblies include a pair of opposing flight arms positioned on either side of the chain with the flight arms each including an elongated body formed with and extending from an integral base and a vertical sprocket opening formed in the integral base. The vertical sprocket opening is configured for engaging a tooth of a drive sprocket to drive the flight arm. The side link assemblies include a pair of opposing side straps positioned on either side of the chain each including a base and a pair of side strap bosses extending outwardly from the base.

Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

Abstract: Military systems in particular face two specific problems: field casualties typically increase as unit visibility decreases and it is often difficult for ground stations and/or headquarters to maintain control and visibility of geographically dispersed assets. The system provides satellite communications such as two-way messaging, Voice over Packet, and global positioning information and reporting for fixed and rotary wing aircrafts where traditional methods of communications are not otherwise practical. The system provides communications between remote users and other remote users as well as between remote users and control stations. In some embodiments there is an in-flight transceiver system that includes an antenna, an aviation box, and a switch. The aviation box conforms to a one-half, ½ short Air Transport Rack (ATR) form factor and includes a transceiver, an interface card, and a global positioning system (GPS) unit.
