Abstract: Driving directions can be helpful if in addition to spatial information, landmark information is provided. Landmarks assist in adding context to directions as well as allowing for a greater likelihood of success of an operator following directions. There can be employment of physical identification of landmarks as well as processing regarding the utility of a landmark in regards to driving directions. Driving directions can be highly useful if integrated landmarks relate to knowledge possessed by an operator of a vehicle. Landmark based driving direction can be integrated with advertisements that relate to the directions.

Abstract: A transistor, such as a FET or bipolar transistor, may be gate or base coupled to a laser driver output stage to receive a varying voltage from a driver output stage. The transistor converts the varying voltage to a varying current. The transistor, in series with the laser, may be coupled to a supply voltage on one side and ground on the other side. Thus, the current supplied to the laser diode is a function of the drive supplied to the transistor's base or gate.
