Abstract: A heat dissipation control apparatus includes a vehicle condition detection device for detecting an operating condition of a vehicle, an occupant detection device for detecting whether an occupant is in the vehicle, a temperature detection device for detecting a temperature of a data recoding unit mounted on the vehicle, a heat dissipation device for dissipating heat from the data recording unit, and a control device for controlling the heat dissipation device in accordance with the detected temperature of the data recoding unit, when the vehicle is in a stopped condition, the data recoding unit is in operation, and no occupant is in the vehicle.

Abstract: An orbital mission planning indicator device provides a visual indication of the relationship between the plane of orbit of an artificial earth satellite and the angle of incidence of solar energy thereon, for all seasons of the year and for arbitrary times and places of launch of such satellite. It also provides indications of the relationship of deep space points of interest to the same orbital plane for adaptability of pointable sensors such as telescopes, antennas and solar arrays to orbital missions calling for use of such equipments.
