Abstract: An imaging system comprising one or more imaging devices wherein each device comprises a lens or lenses which together form an array of lens wherein the array includes two lenses; the two lenses face in opposing directions; the axes of the two lenses are substantially parallel; and the system is adapted to simultaneously capture and record images from the two lenses.

Abstract: A power switching circuit 12 for automatically switching between line-driven and battery power supplies 28 and 30 is disclosed. The power switching circuit selectively connects first and second input voltage terminals Vdd and Vbb to an output voltage terminal Vzz. When the line-driven power supply is on, a first transistor Q1 switches on to connect the first input voltage terminal to the output voltage terminal, and a second transistor Q2 switches off to isolate the battery. When the line-driven power supply is off, the first transistor switches off, and the second switches on to connect the battery powered second input voltage terminal to the output voltage terminal.
