Abstract
The system comprises a headset 38 with infra-red sensors 8,9,11,13,19,21,23,25 mounted on the ear-pieces. In dependence on which sensor receives radiation, a speech synthesiser unit (15 fig 3) produces an output to a speaker (18,28 fig 16) in the ear-pieces giving a message such as "lower front left" to the user 5a. The sensors are protected by circularly polarised lenses.
Description
PERSONAL THREE DIMENSIONAL
THERMAL LOCATION TO THREE
DIMENSIONAL SOUND IMAGING
HEADSET SYSTEM 1. Field of the invention.
The invention relates to headset loudspeakers. More particularly the invention relates to a thermal sensory headset loudspeaker system incorporating a plurality of thermal sensors and speakers mounted on opposite sides of the headset. This system becomes a personal headset for the detection of personnel within the vacinity of the wearer in conditions of poor visibility.
2. State of the art.
There already exist a variety of products that contain the passive infrared detector (2). The detector is mounted behind a circularly polarised lens (1) that is transparent to the passive Infrared electromagnetic spectrum and increases the range of detection and therefore the sensitivity of the device.
The circularly polarised lens also divides the detection regions into zones (4) increasing the coverage region of the detector. The passive infrared detector itself (la) has a detection region that covers 40 degrees from the center of the
X-axis and 45 degrees from the center of the Y-axis. An example of this is the indoor detector (3) that detects the presence of an intruder (S) once he moves into the operating region or zone (4). The alarm system (6) will then enable the external sounder (7) in an attempt to deter the intruder (5) hopefully sending him away. Another example is the Thermal Imaging
Camera (not shown) which can locate the body heat temperature emissions of people that are trapped under objects. The nature of the detector is to locate sources of energy in the 5 to 14 micron wavelength regions, which is commonly referred to as passive Infrared. The detectors that are used in this headset system contain similar passive Infrared sensitive devices.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a personal threedimensional thermal location to three-dimensional sound imaging headset system that detects thermal motion in three dimensions using passive infrared detectors.
It is therefore an object of the present invention to provide a personal three dimensional thermal location to three dimensional sound imaging headset system which converts a signal from the infra-red detectors directly into a three dimensional sound imaging arrangement in the headset. lt is therefore an object of the present invention to provide a personal three dimensional thermal location to three dimensional sound imaging headset system which provides a three dimensional sound imaging arrangement in the form of vocal speech, that offers verbal information according to the position of the detected thermal source.
The above and other objects and features of the present invention will become apparent from the following detailed description and the appended claims with reference to the accompanying drawings.

In accord with these objects will be discussed in detail below the headset system of the present invention which would be constructed by a suitably qualified individual in the subject area to which the invention relates :
A passive infrared detector 8 is preferably flush mounted 8a upon the left enclosure 30.

A passive infrared detector 9 is preferably flush mounted 9a upon the left enclosure 30. Detector range and protection is improved by placing a typical circularly polarised lens cap 9c securely over the detector 9. The detector 9 is then electrically connected to the operational amplifier gain and signal discrimination circuit 9b. A passive infrared detector 10 is preferably flush mounted lOa upon the left enclosure 30.
Detector range and protection is improved by placing a typical circularly polarised lens cap 10c securely over the detector 10. The detector 10 is then electrically connected to the operational amplifier gain and signal discrimination circuit lOb. A passive infrared detector 11 is preferably flush mounted I I a upon the left enclosure 30. Detector range and protection is improved by placing a typical circularly polarised lens cap l lc securely over the detector 11. The detector 11 is then electrically connected to the operational amplifier gain and signal discrimination circuit llb. A passive infrared detector 12 is preferably flush mounted 12a upon the left enclosure 30. Detector range and protection is improved by placing a typical circularly polarised lens cap 12c securely over the detector 12. The detector 12 is then electrically connected to the operational amplifier gain and signal discrimination circuit 12b. A passive infrared detector 13 is preferably flush mounted 13a upon the left enclosure 30. Detector range and protection is improved by placing a typical circularly polarised lens cap 13c securely over the detector 13. The detector 13 is then electrically connected to the operational amplifier gain and signal discrimination circuit 13b.

The detector 14 is then electrically connected to the operational amplifier gain and signal discrimination circuit 14b.
The outputs of operational amplifier gain and signal discriminating circuits 8b, 9b, lOb, 1 lb, 12b, 13b, 14b, are electrically connected to a preprogrammed limited speech synthesizer circuit 15 which provides one of seven simple two word or three word verbal statements in an analogue electrical speech signal format ready for further processing. Each one of the seven simple two word or three word statements is of normal speech duration and becomes available for further processing only when the pre-programmed limited speech synthesizer 15 is instructed to do so by one of the seven 8,9, 10, 11,12,13,14, passive infrared detectors activating the relevant operational amplifier gain and signal discriminating circuits 8b, 9b, 1 Ob, 11 b, 12b, 13b, 14b. In order to prevent an excessive number of verbal statements being issued by the pre-programmed limited speech synthesizer 15 in analogue electrical speech signal format form, to the speaker 18, as a direct result of more than one in number of the passive infrared detectors 8,9,10, 11, 12,13,14 being activated at any one time. An electronic analogue information store circuit or memory chip 16 is electrically connected to the output of the pre-programmed limited speech synthesizer 15. The electronic analogue information store circuit or memory chip 16 places the incoming analogue electrical speech signals from the pre-programmed limited speech synthesizer 15 into a sequential order for processing by the speaker 18. A short time duration is placed between each of the analogue speech signals received by the electronic analogue information store circuit or memory chip 16 during reproduction by the speaker 18, allowing sufficient time for the wearer of the present invention to decipher clearly the verbal statements issued by it.
A passive infrared detector 19 is preferably flush mounted 19a upon the right enclosure 31. Detector range and protection is improved by placing a typical circularly polarised lens cap 19c securely over the detector 19. The detector 19 is then electrically connected to the operational amplifier gain and signal discrimination circuit 19b.

A passive infrared detector 24 is preferably flush mounted 24a upon the right enclosure 31. Detector range and protection is improved by placing a typical circularly polarised lens cap 24c securely over the detector 24. The detector 24 is then electrically connected to the operational amplifier gain and signal discrimination circuit 24b. A passive infrared detector 25 is preferably flush mounted 25a upon the right enclosure 31. Detector range and protection is improved by placing a typical circularly polarised lens cap 25c securely over the detector 25. The detector 25 is then electrically connected to the operational amplifier gain and signal discrimination circuit 25b. The outputs of operational amplifier gain and signal conditioning circuits 19b, 20b, 21b, 22b, 23b, 24b, 25b, are electrically connected to a pre-programmed limited speech synthesizer circuit 26 which provides one of seven simple two word or three word verbal statements in an analogue electrical speech signal format ready for further processing.
Each one of the seven simple two word or three word statements is of normal speech duration and becomes available for further processing only when the pre-programmed limited speech synthesizer 26 is instructed to do so by one of the seven 19,20,21,22,23,24,25, passive infrared detectors activating the relevant operational amplifier gain and signal discriminating circuits 19b, 20b, 21b, 22b, 23b, 24b, 25b. In order to prevent an excessive number of verbal statements being issued by the pre-programmed limited speech synthesizer 26 in analogue electrical speech signal format form, to the speaker 28, as a direct result of more than one in number of the passive infrared detectors 19,20,21,22,23,24,25 being activated at any one time. An electronic analogue information store circuit or memory 27 is electrically connected to the output of the pre-programmed limited speech synthesizer 26.
The electronic analogue information store circuit or memory 27 places the incoming analogue electrical speech signals from the pre-programmed limited
Speech synthesizer 26 into a sequential order for processing by the speaker 28. A short time duration is placed between each of the analogue speech signals received by the electronic analogue information store circuit or memory 27 during reproduction by the speaker 28, allowing sufficient time
for the wearer of the present invention to decipher clearly the verbal
statements issued by it. Figure 5 shows from the wearers perspective the
passive infrared detector placements 8a, 10a, 12a, 14a upon the rear most
side of the left enclosure 30 of the headset for the relevant infrared detectors
numbered 8,10,12 and 14. Figure 6 shows the end view of the left enclosure
30 with the passive infrared detector placements 8a, 9a, 10a, lla, 12a, 13a and 14a upon the end of the left enclosure 30 of the headset for the relevant
infrared detectors numbered 8,9,10,11,12,13 and 14. Figure 7 shows from
the wearers perspective the passive infrared detector placements 8a, 9a, 11 a, 13a upon the forward most side of the left enclosure 30 of the headset for the
relevant infrared detectors numbered 8,9,11, and 13.
Figure 8 shows from the wearers perspective the passive infrared detector placements 19a, 2 la, 23 a, 25 a upon the rear most side of the right enclosure 31 of the headset for the relevant infrared detectors numbered 19,21,23 and 25.
Figure 9 shows the end view of the right enclosure 31 with the passive infrared detector placements 19a, 20a, 21 a, 22a, 23a, 24a and 25a upon the end of the right enclosure 31 of the headset for the relevant infrared detectors numbered 19,20,21,22,23,24 and 25. Figure 10 shows from the wearers perspective the passive infrared detector placements 8a, 9a, 11 a, 13a upon the forward most side of the right enclosure 31 of the headset for the relevant infrared detectors numbered 8,9,11, and 13.
Figure 11 shows an internal end view of the left enclosure 30 of the headset showing the centrally mounted speaker 18. Figure 12 shows a transparent external and vertical end view of the left enclosure 30 of the headset showing the centrally mounted speaker 18. Figure 13 shows an internal end view of the left enclosure 31 of the headset showing the centrally mounted speaker 28.
Figure 14 shows a transparent extemal and vertical end view of the left enclosure 31 of the headset showing the centrally mounted speaker 28.
Referring now to the example given by Figure 16 the illustration shows a hollow injection molded headphone apparatus incorporating two generally ovaloid enclosures 30,31 both contain mountings at the rear (not shown) to support the surface mount electronics 34, 34a necessary for the proper operation of the present invention. Speakers 18a, 28 necessary for the audio message output are mounted securely at 18a and 28a respectively. The sound dispersions 40a, 40 of the speakers 18a and 28a respectively are typical of most headphone transducers (not shown) and oppose the wearer's-Sa-ear canal (not shown). Foam ear-pads 32, 33 are provided for comfort as indicated.
Examples of suitable power supplies 36, 36a are given as indicated within the headband 38. A prototype model was constructed and tested utilising a pair of conventional headphones. Five infrared detectors were three dimensionally arranged upon each side of the headphone and no speech synthesizer was used.
Instead the test model had an electronic auditory tone generator circuit and further electronics, which produced a single tone once a single detector had detected thermal motion. Each detector produced a tone of different pitch in order to differentiate between any one of the ten thermal detectors. The person wearing the headphone was requested to remain stationary whilst a test subject was allowed to move freely in the vicinity of the detection region. The wearer soon became accustomed to the tonal pitch variations and could readily determine from the differing pitches the approximate direction of the test subject with their eyes closed. In another example a typical helmet was constructed in a similar manner and yielded the saune result. Subsequently the present invention was derived from these earlier test results.
