- This invention relates generally to control and response systems and units, and more particularly to electronic security systems useful for operating locks in a security institution which prevent unauthorized operation of locks.
- This invention employs a portable signaling unit, capable of activating a number of response units, which comprises a matrix of lights in spatial arrangement which are energized by corresponding selectively operable switches according to a different predetermined coded combination for each lock.
- the response units at various lock locations each comprise a matrix of photoconductive cells in spatial arrangement corresponding to that of the lights of the signaling unit and operatively conductive in response to illumination therefrom, the photoconductive cells being arranged in circuits to operate the lock only when all of the predetennined coded combination of cells are illuminated, and to prevent activation of the lock if any other photoconductive cells are illuminated.
- the coding information required to operate the system of the present invention is provided by selective operation of the switches located on the signaling unit.
- the different predetermined coded combination of switch operations required to activate each lock is memorized by an authorized lock operator. Since operation of any switch other than that comprising the predetermined coded combination will operate to prevent activation of the lock, theft or loss of the signaling units will not result in unauthorized lock operation. Furthermore, if unauthorized operation of any lock is unsuccessfully attemped, the lock is rendered deactivated until the system is reset from a remote location.
- FIG. I is a side elevation of a hand-held portable signaling unit embodying the present invention.
- FIG. 2 is a front elevation view of the signaling unit illustrated in FIG. 1;
- FIG. 3 is a simplified electrical schematic diagram of the signaling unit illustrated in FIGS. 1 and 2;
- FIG. 4 is an electrical schematic diagram of one of the response units operated by the signaling unit.
- the signaling unit illustrated generally at 10, comprises a hand-held portable device comprising a handle 11 and a body 12 having a front face 13 and a rear face 14.
- a matrix of light generating means or lights 16 is mounted in spatial arrangement partially inside the front face I3 such that the illumination of each of said lights is operatively directed forward from the signaling unit 10.
- a corresponding matrix of selectively operable switches 17 is provided on the rear face 14, each of said switches 17 corresponding to a particular one of said lights 16, for simultaneously energizing a preselected coded combination of lights 16, in conjunction with a master switch 18, from a battery 19 mounted within the body 12, the circuit being illustrated in FIG. 3.
- An operator first sets or closes the memorized preselected combination of switches 17 corresponding to the lights 16 which are desired to be illuminated and then energizes said com. bination of lights 16 upon closing master switch 18, which is preferably of the momentary contact type. It should be noted that, because of the large number of lights 16 and corresponding switches 17, there are many possible combinations of lights 16 that can be illuminated.
- the response units are fixedly mounted at various lock locations and are operable by a portable signaling unit 10 to activate a lock.
- a response unit illustrated generally at 21, comprises a matrix of light responsive conducting means or photoconductive cells, partially illustrated in that figure for purpose of simplification.
- the photoconductive cells of the response units comprise two groups: the activation photoconductive cells 22 connected in series circuit arrangement, and the inhibiting photoconductive cells 23 connected in parallel circuit arrangement. Both groups comprise the matrix of photoconductive cells which are mounted in spatial arrangement corresponding to the spatial arrangement of the lights 16 of the signaling unit 10.
- the signaling unit 10 is held next to a response unit such that the matrix of lights 16 is located directly opposite and adjacent to the matrix of photoconductive cells of the response unit 21, whereby each photoconductive cell is operatively conductive in response to illumination from a corresponding light 16.
- the matrix of photoconductive cells comprises a combination of activation photoconductive cells 22, with the remaining photoconductive cells comprising the group of inhibiting photoconductive cells 23.
- the response unit 21 comprises a sealed box or case containing the electrical connection such that it is impossible to determine which photoconductive cells of the matrix comprise the group of activation photoconductive cells 22 by visual inspection of its exterior. Furthermore, the external case of the response unit 21 is pref-.
- the response unit 21 comprises a source of electrical energy 24, preferably an externally supplied DC source interconnected with an emergency portable rechargeable battery, in parallel circuit arrangement with the group of activation photoconductive cells 22 and the group of inhibiting photoconductive cells 23, only a few of the photoconductive cells of each said group being illustrated in H6. 4.
- the group of activation photoconductive cells 22, interconnected in series, comprises a plurality of photoconductive cells spatially distributed in the matrix of photoconductive cells according to a predetermined coded arrangement which may vary with each of the response units 21.
- the remaining photoconductive cells of the matrix comprises the group of inhibiting photoconductive 23, which are interconnected in parallel.
- a lock activation relay coil 26 of a lock activation relay is connected in series with the group of activation photoconductive cells 22 and is operatively energized from the DC source 24 in response to simultaneous conduction of all of the activation photoconductive cells 22.
- An in hibiting relay coil 27 of an inhibiting relay is similarly connected in series with the group of inhibiting photoconductive cells 23, but is operatively energized from the DC source 24 in response to conduction of any of the inhibiting photoconductive cells 23.
- the lock activation relay coil 26 operates to energize a lock solenoid 28 from the DC source 24, which results in the opening of the desired lock (not illustrated).
- response unit 21 will operate a lock only when all of the activation photoconductive cells 22 are illuminated by corresponding lights 16 of the signaling unit and none of the inhibiting photoconductive cells 23 are also illuminated, in order to prevent unauthorized operation of the lock.
- the lock activation relay coil 26 operates to close normally open relay contacts 29 of the lock activation relay by moving movable relay contact 31 into engagement therewith in order to energize the lock solenoid 28 from the DC source 24 through a time delay switch 32 and normally closed relay contacts 33 of the inhibiting relay.
- the time delay switch operating to delay completion of the lock solenoid circuit by a period of time, preferably on the order of 0.75 seconds, prevents energization of the lock solenoid 28 until the inhibiting relay coil 27 has sufficient time to open the normally closed relay contact 33 and to close normally open relay contacts 34 by means of a movable relay contact 36, if the inhibiting relay coil operates at all.
- an alarm light 37 preferably remotely located from the response unit 21, is energized from the DC source 24 when the normally open relay contacts 34 are closed by the movable relay contact 36.
- the inhibiting relay is further provided with conventional latching means to prevent restoration of the inhibiting relay contacts to their normal positions until released and reset by an inhibiting relay control solenoid 38, which is energized from the DC source 24 through a pushbutton switch 39, preferably remotely located from the response unit 21.
- an inhibiting relay control solenoid 38 which is energized from the DC source 24 through a pushbutton switch 39, preferably remotely located from the response unit 21.
- the light generating means or lights 16 of the signaling unit 10 could be selected to emit light at different frequencies according to a predetermined code, with corresponding activation photoconductive cells 22 responsive only to illumination at those particular frequencies by means of light filters, for example, in order to render the system of the present invention even more secure from tampering.
- a coded signal system comprising:
- signaling means having a plurality of selectively operable switches, a source of electrical energy and a plurality of light generating means in spatial arrangement, all in a circuit for simultaneously activating selected ones of said plurality of light generating means by energization from said source; response means having a first plurality of light responsive conducting means in series circuit arrangement, a second plurality of light responsive conducting means in parallel circuit arrangement, each of said light responsive conducting means being spatially located opposite a corresponding one of said light generating means and operatively conductive in response to illumination therefrom when said signaling means is operatively positioned relative to said response means; a source of electrical energy, and an activation relay in circuit with said first plurality and said source and operable to connect said source to a desired load in response to illumination of all of said first plurality of light responsive conducting means, and an inhibiting relay in circuit with said second plurality and said source and operable to isolate said source from said load in response to illumination of any of said second plurality of light responsive conducting means; whereby said load is energized only in response
- each said light generating means is operable to emit light at a different frequency according to a predetermined code
- each light responsive conducting means of said first plurality is operatively conductive in response to illumination from a corresponding one of said light generating means only at a particular frequency.
