Abstract

A monitor utilizes a sensor which transmits a signal when a specific phenomenon has occurred. The time of the phenomenon is recorded in memory for later withdrawal and analysis by the operator. Being small, palm-sized, the monitor can easily be attached to such items as a drawer to monitor when the drawer is opened. Additionally, through the use of two-sided adhesive tape or the like, the security monitor can be easily moved from one location to another.

Claims

1. An occurrence monitor comprising:

a. a sensor means for generating an electrical signal upon the occurrence of a preselected physical phenomenon within the environment surrounding the occurrence monitor; and

,

b. a palm sized monitor having;

1 a clock means,

2. a connector means for connecting/disconnecting said sensor means to said palm sized monitor,

3. an electronic memory means,

4. a controller means in communication with said clock means, said sensor means, and said electronic memory means, said controller means recording in said electronic memory means, the time as defined by said clock means, of any electrical signal received from said sensor means via said connector means, and,

5. fastening means permitting said palm sized monitor to be coupled to and decoupled from a selected object.

2. The occurrence monitor according to claim 1 further comprising an operator communication means and wherein said controller means communicates data stored within said memory means to an operator.

3. The occurrence monitor according to claim 2 wherein said operator communication means includes a display device.

4. The occurrence monitor according to claim 2 wherein said fastening means includes a double sided adhesive tape.

5. The occurrence monitor according to claim 2 wherein said fastening means includes at least two strips of bonding cloth material wherein a strip of bonding cloth material will cling to a second strip of bonding cloth material.

6. The occurrence monitor according to claim 2 wherein said sensor means includes means for sensing a preselected level of light.

7. The occurrence monitor according to claim 2 wherein said sensor means includes means for sensing the existence of a preselected level of current within an electrical conductor.

8. The occurrence monitor according to claim 2 wherein said sensor means includes switching means being activatable upon the movement of a physical item.

9. A method of deploying a security monitor including the steps of:

a. mounting said security monitor in an unobtrusive location;

b. connecting to said monitor, a sensor which generates a signal upon the occurrence of a selected phenomenon; and

,

c. causing said monitor to record the time of any occurrence of the selected phenomenon.

10. The method of deploying a security monitor according to claim 9, further including the step of communicating the times of all recorded occurrences of said selected phenomenon.

11. The method of deploying a security monitor according to claim 9, further including the step of initializing the time of said security monitor to local time prior to the mounting of said security monitor.

12. A method of operating a security monitor including the steps of repetitively:

A. monitoring the input line of a remote phenomenon-sensor for a signal, once having the input,

1. obtaining the time of said input from a clock, and,

2. recording the time of said input within a memory unit;

B. checking an operator interface to determine if there exists operator-generated interrupt data thereon and upon the existence of said operator-generated interrupt data,

1. activating a display device, and

2. communicating all material stored within said memory unit to the operator.

13. The method of operating a security monitor according to claim 12, including after activating the display device, the steps of:

A. prompting the operator for entry of a security code; and

B. comparing the entered security code with a preselected stored code.

14. The method of operating a security monitor according to claim 13, including, after the step of comparing the entered security code to a preselected code, the step of aborting operation should the entered security code and the stored code do not match.

15. The method of operating a security monitor according to claim 13, including, after the step of comparing the entered security code to a preselected code, the step of storing the time of said comparison within said memory device.

16. A security kit comprising:

A. a security monitor having,

1. clock means for generating data identifying the time of day,

2. electronic memory means for the storage of data,

3. an input port for the receipt of an electrical signal, and,

4. a control means for,

a. monitoring the input port for the existence of said electrical signal,

b. obtaining from the clock means data relative to the time of said electrical signal, and,

c. storing the data from said clock means within said electronic memory means;

B. at least two sensors being individually connectable to said security monitor via said input port, each of said sensors capable of causing an electrical signal to be communicated upon the occurrence of a physical phenomenon surpassing a preselected threshold; and

,

C. means to attach said security monitor to a selected item.

17. The security monitor kit according to claim 16 wherein each of said sensors is activated by a different physical phenomenon.

18. The security monitor kit according to claim 16 wherein said means to attach are detachable.

19. The security monitor kit according to claim 16 wherein one of said sensors is activated by the existence of light beyond a preselected threshold.

20. The security monitor kit according to claim 16 wherein one of said sensors is activated by the existence of current within a conductor beyond a preselected threshold.

21. An occurrence monitor comprising:

a. a sensor means for generating an electrical signal upon the occurrence of a preselected physical phenomenon within the environment surrounding the occurrence monitor;

b. a palm sized monitor having;

1. a clock means,

2. operator communication means including a display device,

3. operator input means for communicating data from an operator,

4. a connector means for connecting/disconnecting said sensor means to said palm sized monitor,

5. an memory means,

6. a controller means in communication with said clock means, said sensor means, and said memory means, said controller means recording in said memory means, the time as defined by said clock means, of any electrical signal received from said sensor means via said connector means, and wherein the controller means communicates data stored within said memory means to an operator via said operator communication means, and, wherein said controller means deactivates said display device except upon the input of selected data from said operator, and,

7. fastening means permitting said palm sized monitor to be coupled to and decoupled from a selected object.

22. The occurrence monitor according to claim 21 wherein the data generated from an operator via said operator input means causes said controller means to erase all occurrence data from said memory means.
