摘要： There is provided a charging device capable of improving charging efficiency and reducing power consumption, thereby increasing a battery service life. The charging device charges a main capacitor (2) by rectifying output voltage boosted via a self-excitation DC-DC converter, by using a diode (D). The self-excitation DC-DC converter is configured as follows. When a current value (I1) flowing in a primary side (P) of an oscillation transformer (T) reaches a first predetermined value (IPK1) the excitation period is terminated and energy is transmitted from the primary side (P) to the secondary side (S) of the oscillation transformer (T) so as to execute a charging period for charging the main capacitor (2). The excitation period is resumed with a delay time (t1) after detecting that the current value (I2) flowing into the secondary side (S) of the oscillation transformer (T) is lowered than a second predetermined value (Ith2).

摘要： In a motion verifying photography method, a latent image is captured during a film exposure time interval. The film exposure time interval has an initial portion, a middle portion, and a final portion. A first digital image is captured during the initial portion of the film exposure time interval. A second digital image is captured during the final portion of the film exposure time interval. A representation of both electronic images is visualized. A motion verifying camera has an exposure frame, an electronic array imager spaced from the exposure frame, an optical system directing light along a first path to the exposure frame and along a second path to the imager. Shutters are disposed on both paths. A shutter release connects to an actuator and responsive to the actuator, momentarily opens the film shutter for a film exposure time interval having an initial portion, a middle portion, and a final portion. The actuator momentarily opens the imager shutter during the initial portion and momentarily opens the imager shutter during the final portion.
