Abstract: A toilet system that includes a waste receptacle including an outlet configured to channel waste therethrough. The system also includes a conveyor assembly including a housing that includes an inlet and at least one outlet. The inlet is coupled in flow communication with the outlet of the waste receptacle. The conveyor assembly also includes a transport mechanism positioned within the housing, and the transport mechanism is operable to actively transport the waste from the inlet towards the at least one outlet of said housing.

Abstract: A modular roadway structure that includes a body portion including a bottom surface and a top surface. The bottom surface is configured to be positioned on a surface, and the top surface is formed with a predetermined textured pattern for defining a predetermined coefficient of friction across the top surface.

Abstract: An aircraft communications system is located on an aircraft. The aircraft communications system comprises a set of eyewear units, an aircraft data processing system, and a wireless system. Each eyewear unit has a set of sensors and a display. The set of eyewear units is capable of receiving user input and is capable of presenting information to a set of users of the set of eyewear units. The aircraft data processing system is capable of receiving the user input and sending the information to the set of eyewear units in response to receiving the user input from the set of eyewear units. The wireless system is located proximate to the cabin of the aircraft and is capable of sending the user input from the set of eyewear units to the aircraft data processing system and sending the information to the set of eyewear units.

Abstract: A strength training machine for exercising the muscles of the lower leg that lift the foot toward the body, namely the tibialis anterior. The machine includes a frame that supports a seat and either one or two foot positioning devices, such that a seated user can insert his or her feet into the positioning device(s). The positioning device(s) are rotatably supported by the frame with an axis of rotation that approximately intersects the location of the ankles when the feet are inserted into the positioning device(s). A cam, cable, and pulley system connect each positioning device to weights, thereby providing resistance to ankle dorsiflexion.
