Switch activating system and method
First Claim
1. An electrically operated lock system comprising in combination:
- first means for opening and closing a switch,second means for operating said first means to cause said first means to close said switch,said second means including electrically controllable means and a short wave pick-up operatively connected to said electrically controllable means,third means including a portable short wave code generating and transmitting means adapted to be carried by a person seeking to activate said circuit by closing said switch,fourth means connected to said pick-up of said second means and operable for electrically detecting short wave codes generated by said third means, said fourth means being operable to activate said second means to control the operation of said first means,said first, second and fourth means being supported on a common support,said third means being automatically operable when carried to a given range of said fourth means to generate a short wave code receivable by said pick-up and detectable by said fourth means for causing said fourth means to generate a control signal for controlling said second means to close said switch whereby said switch may be employed to connect a source of electrical energy to an electrical circuit when so closed.

Abstract
A system and method for activating an electrical circuit for control purposes by bringing a portable electrical code generator or field modifying electrical circuit into a short wave energy field generated in the vicinity of a short wave receiver and causing energy of said field to be absorbed by said portable circuit and to trigger or energize the portable code generating circuit to cause it to generate a short wave code which is received by said short wave receiver. A code detector in the output of said short wave receiver detects the code received and activates the relay or switch which effects the control of an electrically activated device or circuit by supplying electrical energy thereto. The portable device may be supported by a finger ring, wristband, card or other means.

6. An electrically operated switching system comprising:
-
first means for opening and closing a switch in an electrical circuit to activate said circuit when said switch is closed, second means including electronic control means and a short wave pickup operatively connected to said electrical control means, third means including a portable short wave code generating and transmitting means adapted to be activated when in the vicinity of said short wave pickup to generate a code signal and to short wave transmit said code signal to said pickup, and means for converting the code signals received by said short wave pickup to electrical code signals, fourth means connected to said pickup and responsive to said electrical code signals generated from the short wave code signals received by said pickup for generating a control signal, fifth means for receiving said control signal, sixth means including circuit means, a source of electrical energy and a switch adapted to activate said electrical circuit means by connecting said source of electrical energy to said circuit means when said switch is closed, said fifth means being connected to said sixth means for activating said switch when said code electrical signals are received by said fifth means.

7. A method of gaining access to a security location comprising:
-
providing a short wave generating means carried by a person seeking access to said security location, and when it is desired to gain access to said security location, bringing said short wave code generating means into a predetermined range of an energy field generating means and the energy field thereof and to within an operable range of a short wave receiver of the code of said code generating means and causing energy of said energy field to energize said short wave code generating means to automatically generate a short wave code, receiving said short wave code and thereafter generating electrical signals representative of the code automatically generated, and applying said electrical signals to an electronic analyzing and control circuit and automatically analyzing said signals by means of said electronic circuit whereby the applied signals are processed and whereby the analysis of such signals is effected by comparing the received code signals with signals derived from a memory and generating a control signal when a match occurs between said received code signals and signals reproduced from said memory, and applying said control signal to effect a control function for enabling access to said security location. - View Dependent Claims (8)
