Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a system for monitoring the health and viability of security guards and/or guard dogs. In particular, the invention relates to a sensor attached to a guard or guard dog that alerts emergency services if the guard is in distress or has been killed, so that back-up security can be sent in.

2. The Prior Art

Health sensors are known, in which health care professionals are alerted when a patient is in distress. These often are in the confines of a hospital and involve cumbersome equipment.

Wireless sensors are also known, in which the state of the patent is transmitted wirelessly to a remote receiver. An example of this is US Patent Application Publication No. 2007/0004969 to Kong.

While there are several patents and patent applications related to sensing the health of patients, this technology has not been adapted to security systems. It would be desirable to incorporate a biological sensor into a security system to alert authorities when a guard has been disabled or killed.

SUMMARY OF THE INVENTION

In view of the foregoing, it is an object of this invention to provide a security system that monitors the state of at least one guard and transmits any changes in the biological state of the guard to a remote receiver, which can automatically alert authorities to send in a replacement.

This object is accomplished by a system and method for monitoring the state of a guard, in which a biological sensor is attached to the guard, and a wireless transmitter is attached to the sensor. The transmitter transmits any changes in the biological state of the guard to a remote receiver. The remote receiver can be programmed to automatically send an alert to various entities, which can then send in replacements.

The sensor can be a heart rate sensor, a respiration sensor, a temperature sensor, a noise sensor, a brain wave sensor, or any other type of sensor, based on the requirements of the user. Typically, the sensor will be a heart rate sensor. An increased heart rate can signal distress, while lack of a heartbeat can signal death of the guard. If the guard is a guard dog, the sensor can also be a noise sensor, because a barking dog can signal danger as well. The microprocessor can screen out other noises, so that only the sound of barking triggers the transmitter to transmit to the receiver.

A camera can be connected to the sensor, to show the surrounding area when the sensor indicates distress or death. This can be helpful to identify dangerous persons or things and to show the state of the surrounding area. The camera can be automatically activated when the sensor senses a change in the biological condition or noise outside of a predetermined threshold.

The receiver is preferably a mobile telephone. The mobile telephone can be programmed to automatically call security authorities with a prerecorded distress message, either that the guard is in distress and requests assistance, or that the guard has been killed. The mobile telephone can have a computer and a display so that the physical parameters that are sensed can be displayed on the display. The display can be activated only when the sensor senses a change in one of the parameters, or can be a continuous display.

The sensor can be attached to the guard in any suitable manner, such as by adhesive, or strapped on as in a wrist watch or arm band or head band. In the case of a guard dog, the sensor can be attached to the dog's collar.

The system can also include a GPS (Global Positioning System) receiver connected to the transmitter. The transmitter transmits the location of the GPS receiver along with the data sensed by the sensor to the receiver when the sensor senses a change in the physical parameter.

The transmitter can be programmed via a microprocessor to only transmit when the change in physical parameters is sufficient enough to cause concern. For example, a change in heart rate that exceeds 20% of a resting heart rate, a drop or increase in body temperature of more than 3 degrees F., a significant change in brain wave activity, etc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIG. 1, the system according to the invention comprises a module 1, which is worn by a guard 10, either human or canine, via an attachment device, such as a wrist band 11, or a dog collar 18, as shown in FIG. 3. As shown in FIG. 2, module 1 consists of a sensor 12, which is adapted to sense a physical parameter of the animal or human on which the sensor is placed, and a microprocessor 13, which processes the data sensed by the sensor. Connected to microprocessor 13 is a transmitter 14, which, as controlled by microprocessor 13, transmits data sensed by sensor 13 to a remote location, namely receiver 20. Receiver 20 is a mobile telephone, which is equipped with an internal, internet-capable computer 24 and a display 21. Receiver 20 receives data transmitted from transmitter 14 over the internet or a cellular network, which is then displayed in the form of graphical data 22 on display 21. Receiver 20 can be automatically programmed via computer 24 to call a command center 30 with a warning signal or message when receiver 20 receives data from transmitter 14 that indicates a significant change in the physical parameters, thus indicating a security breach, danger, injury to or death of the guard, which will then alert the command center to send in additional guards.

Also connected to microprocessor 13 is a video camera 15, which is controlled by microprocessor 13 to begin recording the surrounding area when sensor 12 senses a change in the measured physical parameters. This can provide additional information to the command center in the event of an emergency. Video data from video camera 15 is sent via transmitter 14 to receiver 20 where it also can be viewed on display 21.

A GPS receiver is also be connected to microprocessor 13. When sensor 12 senses a change in the physical parameters of guard 10, transmitter 14 transmits the location of guard 10 to receiver 20, along with the sensor data and video data. All of this can be passed on to command center 30 via cellular signals or data transmission over the internet. Computer 24 in receiver 20 can vary the transmission of signals to command center 30 based on the level of threat detected by sensor 12. For example, if sensor 12 detects an elevated heartbeat of the guard 10, then computer 24 might categorize this as a mild threat or security breach and this information can then be sent to command center 30. However, if sensor 12 detects a lack of heartbeat of guard 10, then computer 24 can categorize this as an urgent warning to be sent to command center 30. The warnings can take the form of recorded voice instructions, alarm bells, text messages, flashing lights or any other type of warning.

The system according to the invention can provide instantaneous data regarding the state of a human sentry or a guard dog to a remote command center, which can then act to send in reinforcements as soon as a dangerous situation occurs. The system alerts the command center of the situation even when the guard is disabled or dead, because the change in the physical parameters measured by the sensor triggers the communication system and does not require action by the guard. The microprocessor 13 can be programmed to trigger the transmitter 14 when the change in parameters exceeds certain thresholds, such as 20% above or below a normal resting heartbeat, a drop or increase in body temperature of more than 3 degrees, a change in brain waves, etc.

Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
