Abstract: An indicator unit is provided to display information to occupants in a motor vehicle. The indicator unit is adapted for connection to a communication network and intercepts messages that carry data between other vehicle equipment. A control circuit is programmed to identify the existing network messages that carry the data needed for the information display. The control circuit operates a display device in response to received data. Because the indicator eavesdrops on the network and intercepts existing data messages, other equipment in the motor vehicle do not have to be programmed to communicate specifically with the indicator. This facilitates adding specific indicators to a particular truck.

Abstract: A visible helium neon beam is used as an aiming beam to establish a spot at which a carbon dioxide beam also focuses. The carbon dioxide beam is then employed to vaporize biotic material. A distal end of an articulated arm may couple with the micromanipulator to direct the carbon dioxide beam from the laser through a waveguide and into the micromanipulator. Another aspect of the invention includes introducing the aiming beam into the waveguide through a dichroic mirror positioned in a knuckle joint of the articulated arm. In one embodiment, a laser diode generates the visible light of the aiming beam, and is disposed proximate to the distal end of the articulated arm.
