Abstract (en)
[origin: US4763310A] A solar powered electronic clock has a display, time-keeping electronics, a battery, and a solar cell array. The battery is chargeable from the solar cell array and supplies only the time-keeping electronics while the display is powered only by the solar cell array. A diode connected between the solar cell array and battery permits the battery to be recharged, but prevents the display from drawing energy from the battery.
