Abstract

The present invention is a system for encouraging workers who work in a hygienically controlled area to wash their hands before exiting an associated sanitation area. Broadly, the present invention comprises a housing located in the sanitation area for receiving at least a portion of the hands of the worker. A detector is operatively associated with the housing. The detector detects whether or not the hands of the worker have recently been washed in response to the insertion of the hands of the worker into the housing. A communication media is also operatively associated with the detector for outputting one of a sanitary signaling media in response to the detection that the hands of the worker have been washed and an unsanitary signaling media in response to the detection that the hands of the worker have not been washed.

Claims

1. A system for encouraging workers who work in a hygienically controlled area to wash their hands before exiting an associated sanitation area, comprising:

a badge element for each worker;

an unsanitary signaling media on each badge element;

means for attaching the badge element to the worker; and

means for enabling the unsanitary signaling media in response to the attaching of the badge element to the worker.

2. A system as recited in claim 1, further comprising:

a sanitary signaling media on each badge element; and

means for enabling the sanitary signaling media to indicate that the worker has likely washed his or her hands with soap and water.

3. A system as defined in claim 2, wherein the means for enabling the sanitary signaling media includes:

a soap mixture in the sanitation area containing a detectable substance; and

detector means located in the sanitation area for enabling the sanitary signaling media responsive to the detection of a concentration of the detectable substance within a preselected range.

4. A system as defined in claim 3, further comprising:

a tamper signaling media on each badge element; and

wherein the detector means includes means for enabling the tamper signaling media responsive to the detection of a concentration of the detectable substance above the preselected range.

5. A system as recited in claim 1, wherein the means for attaching the badge element includes:

a clip switch attached to the badge element for attaching the badge element to the worker;

and wherein the means for enabling includes;

means for sensing the attaching of the clip switch to the worker for activating the badge element.

6. A system as recited in claim 1, further comprising:

a first transmitter positioned in the sanitation area, the first transmitter transmitting a signal;

a compatible receiver on each badge element to receive the signal from the first transmitter when the worker wearing the badge element enters the sanitation area;

means for enabling the unsanitary signaling media on the badge element in response to the receiver receiving the signal from the first transmitter;

means for disabling the unsanitary signaling media to indicate that said worker has likely washed his or her hands with soap and water; and

means for disabling the reception of the signal by the receiver for the passage of a predetermined time period subsequent to the unsanitary signaling media being disabled whereby the worker who likely washed his or her hands can exit the sanitation area in the predetermined period without the unsanitary signaling media being reenabled.

7. A system as defined in claim 1, further comprising:

a tamper signaling media on each badge element;

a light sensitive receiver on each badge element and positioned to receive light when the worker is wearing the badge element; and

means for enabling the tamper signaling media in response to the absence of the light sensitive receiver receiving light for the passage of a predetermined period of time.

8. A system for encouraging workers who work in a hygienically controlled area to wash their hands before exiting an associated sanitation area, comprising:

a soap containing a detectable substance, for being disposed on the worker'"'"'s hands when the worker washes their hands;

detection means for detecting the presence of the detectable substance on the hands of the worker; and

communication means operatively associated with the detection means for communicating an unsanitary signaling media responsive to the detection of the presence of the detectable substance on the hands of the worker below a preselected range.

9. A system as recited in claim 8, wherein the detection means includes a housing separate from a hand dryer, and wherein the housing of the detection means defines a compartment sized to receive the hands of the worker and the detection means further includes:

a substance detector; and

means for moving air from the compartment to the substance detector.

10. A system as recited in claim 8, wherein the communication means further comprises means for communicating a tamper signaling media responsive to the detection of the presence of the detectable substance on the hands of the worker above the preselected range.

11. A system as recited in claim 8, wherein the detector means includes:

a housing supported by a supporting structure,

the housing comprising;

a first compartment; and

a second compartment sized to receive the hands of the worker, the second compartment defining a first opening to permit workers to dispose their hands through the first opening and into the second compartment;

an unsanitary signaling media on the housing;

a sanitary signaling media on the housing;

a tamper signaling media on the housing;

a substance detector disposed on the housing and being capable of outputting a signal indicative of the concentration of the detectable substance detected on the hands of the worker;

means on the housing for moving air from the second compartment to the substance detector; and

system board means disposed in the first compartment for receiving the signal output by the substance detector, and for enabling the unsanitary signaling media responsive to the concentration of the detectable substance being below a predetermined range, and for enabling the sanitary signaling media responsive to the concentration of the detectable substance being within the predetermined range, and for enabling the tamper signaling media responsive to the concentration of the detectable substance being above the predetermined range.

12. A system for encouraging workers who work in a hygienically controlled area to wash their hands before exiting an associated sanitation area, comprising:

means located in the sanitation area for receiving at least a portion of the hands of the worker;

detector means, operatively associated with the means for receiving, for detecting whether or not the hands of the worker have recently been washed subsequent to the insertion of the hands of the worker into the means for receiving; and

means operatively associated with the detector means for outputting one of a sanitary signaling media in response to the detection that the hands of the worker have been washed and an unsanitary signaling media in response to the detection that the hands of the worker have not been washed.

13. A system as recited in claim 12, further comprising:

a badge element for each worker;

an unsanitary signaling media on each badge element;

means for attaching the badge element to the worker; and

means for enabling the unsanitary signaling media in response to the attaching of the badge element to the worker.

14. A system as recited in claim 13, wherein the means for attaching the badge element comprises:

a clip switch attached to the badge element for attaching the badge element to the worker; and

wherein the means for enabling comprises;

means for sensing the attaching of the clip switch to the worker for activating the badge element.

15. A system as recited in claim 12, further comprising:

a badge element for each worker;

a first transmitter positioned in the sanitation area, the first transmitter transmitting a signal;

a compatible receiver on each badge element to receive the signal from the first transmitter when the worker wearing the badge element enters the sanitation area;

means for enabling the unsanitary signaling media on the badge element in response to the receiver receiving the signal from the first transmitter;
