Filed:

Mar 2, 1988

Appl. No.:

7/163521

Inventors:

Daniel J. Birk - Aurora IL

Assignee:

Pittway Corporation - Northbrook IL

International Classification:

G05D 706

US Classification:

364145

Abstract:

Each of several, typically three, microprocessorcontrolled modular electronic timers is selectably electrically pluggable to each of several, typically four, custom packaged modular switches. Each modular switch contains an indentical switch circuit that selectively implements the SPST through 4PST, the DPDT, or the DPST switch function. Each modular timer variously provides eight on/off events, either upon five weekdays and upon two weekend days, or upon individual days. Each modular timer may skip timed events during a one to seven day period. An astronomical timer generates an on/off signal at local sunrise and sunset without reference to ambient light conditions. Each timer is readily programmed, and toggled in its on/off signal state, by pushbutton switches. A comprehensive display shows current programmed data and on/off signal status. Each modular switch typically has two pairs of relays that are oppositely controlled.

Abstract:

A method for encryption of a private media package by a first processing device which includes at least three key components of a regret management flag, a rules set, and a media object, encrypting with a first key the regret management flag, encrypting with the first key the rules set, encrypting with the first key the media object(s), obtaining a randomized result key, bit shifting the regret management flag from encrypting with the first key the management flag, via the randomized result key, bit shifting the rules set from encrypting with the first key the rules set, via the randomized key, bit shifting the media object(s) from encrypting with the first key the media object(s), via the randomized key, encrypting with a second key the regret management flag from encrypting and bit shifting the regret management flag, encrypting with the second key the rules set from encrypting and bit shifting the rules set, encrypting with the second key the media object(s) from encrypting and bit shifting the media object(s), storing as an encrypted package the regret management flag of the encrypting with the second key the regret management flag, the rules set of the encrypting with the second key the rules set, and the media object(s) of the encrypting with the second key the media object. Decryption is by reverse of the encryption process, and the resulting decrypted private media package may be used only in compliance with the rules set.
