Abstract: A spray boom includes a body having a length defined a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. A hollow cavity is defined in the body internally of the inner surface, and a channel is formed in the body between the inner surface and the outer surface. The channel extends along the length and is defined between the first end and the second end.

Abstract: Concepts and technologies are disclosed herein for controllably opening water supply line doors. The controllably opening water supply line door can include a base that includes a first substantially planar piece of material; a door that can include a second substantially planar piece of material; and a hinge structure that can be joined to the base and the door. The hinge structure can include a hinge. The door can be configured to rotate about an axis formed by the hinge to create a passageway.

Abstract: A spray boom includes a body having a length defined a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. A hollow cavity is defined in the body internally of the inner surface, and a channel is formed in the body between the inner surface and the outer surface. The channel extends along the length and is defined between the first end and the second end.

Abstract: A spray boom includes a body having a length defined between a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. An internal cavity is defined in the body internally of the inner surface. A light-emitting system is integrally formed in the body in an outer layer thereof or at a location between the inner surface and the outer surface. The light-emitting downsystem has an on state and an off state in which it is adapted to emit a light when in the on state.

Abstract: Control systems and methods are provided for controlling a personal communication device (PCD), such as a wireless telephone, personal data assistant (PDA), etc. The control systems and methods enable the controlled PCD (CPCD): (1) to determine (a) CPCD motion (speed, acceleration, or both) and/or (b) geographical location and (2) to (a) modify (enable, disable, and/or otherwise change) one or more CPCD functions based at least in part on the CPCD motion and/or geographical location and/or (b) communicate an alert (locally and/or to a remote communication device). The control of CPCD functions and alerts may also be dependent on other factors, such as the laws of the authoritative legal jurisdiction wherein the CPCD is located.
