Abstract: A method and system for providing a consumer with on-line access to a real estate transaction file is provided. The method includes the steps of verifying that a completed real estate transaction file is in compliance with applicable regulations, preparing the file for conversion into digital form, converting the file into a suitable digital form, checking a quality of the converted file, indexing the converted file for storage in an online database connected to a network, storing the converted file in the online database in accordance with a predetermined document retention policy, and providing the consumer with secure electronic access to the converted file over the network.

Abstract: A first circuit arrangement including a zener diode coupled to the base of a transistor for keeping the transistor turned ON in response to the magnitude of voltage developed across a storage capacitor. The capacitor provides power to a photographic flash tube connected in series with a silicon controlled rectifier (SCR). After the flash tube is ignited, energy is drained from the charged capacitor until its voltage level reaches a predetermined magnitude at which time the zener diode becomes non-conducting, turning OFF the transistor, which causes a commutation of the SCR, terminating the flash of the flash tube. The capacitor is then recharged for preparation of the next flash operation.A second circuit arrangement utilizes a programmable unijunction transistor in which the voltage magnitude of the flash storage capacitor is followed by the gate of the unijunction transistor until the gate voltage reaches a corresponding voltage level preset at the anode of the unijunction transistor.

Abstract: A correct exposure annunciator for electronic flash apparatus includes an indicator which is turned on when the voltage on a capacitor is less than a predetermined value. The capacitor is discharged in response to a control signal which indicates that proper exposure has occurred. The capacitor is then recharged until the voltage on the capacitor attains the predetermined value and turns off the indicator.
