Description

The Health System has been designed to relieve stress related health problems like headaches, tension ,feeling unwell in offices and places of work and sleepless. The system will provide a continuous operation by dispersing essential oil in to the air to permeate the atmosphere with herbal medication thus producing an aroma environment at home and in offices. The benefits of this approach are;- naturally conducive to creating and maintaining the health of members of staff and the individual,self contained operation,easy instalation,safety of operation of the burner. An obvious advantage of this system is its contribution to reducing the time lost due to the above illnesses. The SYSTEM will be designed ergonomicaly so that any loction within the house or office area would be suitable.

The detection system used by OPTOLINK would provide a new concept in sampling method for the monitoring of a room environment.

The system will be designed for installation by the purchaser in the appropriate selected location without any need to dismantle the cover.

The product resulting from this project will be a unique, Enviromentaly Safe, Ambience Creating, Electronic Control Heat Burner, which will be of great significance to the diffusion method used in the existing markets world wide.

This will allow OPTOLINK to move ahead decisively from its position of a new company in the Electronic health system market to being a world wide leader in the emerging Ambience Creation Systems market.

OPTOLINK considers to offer the detection technology to other industries such as failure of Diesel engines by use ofoil mist detection and gas detection 2. TECHNICAL DESCRIPTION The project is to prove the technical feasibility of a electronic monitoring room aeromathearopy system. We would implement a room environment detection system based on the self-biasing configuration in which at any time changes in the room enviroment occur, the transducer (optoelectronic components) will detect this change,thus generating the slow release of essential oils.

The purpose is to produce an enviromentally healthy condition in the offices ,industries and homes where the lack of fresh air and conditions of buildings cause sinusitis, respiratory conditions, migraine, headaches and generally unwell feeling. The use of an essential oil product (which has a self operating circuitory system) would overcome these problems and simultaneously create a feeling of well-being.

The bases for this work would be to produce a high quality self containd electronic air freshner system due to the rise of consumer concern over enviromental issues.At present there is no intelligent system which would provide the required need of this market.

The system would use a transducer optical detection circuit to monitor the room which would then communicate an output signal to an electronic control to start the process of diffusing essential oil in to the atmosphere. The presence of some pollution would be detected by the amount of infrared radiation that the transducer would absorb at characteristic wavelengths.The detection of a particular polluted environment would be carried out by a transducer.Infrared radiation at the characteristic absorbtion wavelength of the gases (selected by narrowband filters) are passed through a reference chamber which contains the sample.

DRAFT SPECIFICATION FOR ELECTRONIC HEALTH SYSTEM 1.DEFINITIONS Electronic Health system is essentially a compact , wall mounted electronic monitoring room aeromathearopy system.

It operates from a.c. Mains supply of 110/220/240 volts.

The system consists cf sub assembles which are each suitable for providing different generation of products.

The technology offered by the development of the electronic system leads to the evolution of a wide range of products in this field 2.PRODUCT RANGE The development of the health system will be aimed at creating a basic building block consisting of the three possible product configurations.

a- A non-intelligent system b- A semi intelligent system ,in which a near constant air concentration of essential oils is maintained using a feedback mechanism.

c- A fully intelligent system , able to monitor environment of the industrial offices, etc and assess this in the light of its location by use of microprocessor sampling control systems.

3.BURNER SYSTEM This system will use high voltage a.c. Mains to provide the required temperature for heating the chemicals. Constant temperature should be maintained throughout the operation of the burner.

The material should be able to insulate the burner system from electrical mains.

The target power required by the burner will be governed by the temperature of the oil reservoir. Control of the current through the heater will be by appropriate circuits, driven by an output from the processor.

BURNER SYSTEM POWER 220/240 & 10 VOLTS DIM 50*50 mm MATERIAL HIGH TEMPERATURE COMPOUND OPERATING TEMP 120'C MAX 4.DETECTION SYSTEM This is the main input of the system and is a d.c. Level related to the environment contamination level of the room being monitored.

Detection method a-OPTICAL SYSTEM b-MECHANICAL SYSTEM OPTOLINK will consider using optical system as this proves to be the most efficient way.

The concentration of airborne compound may be measured using an optoelectronic transducer. Absorption patterns characteristic to harmful substances will be recognised by the system, and a measure of the concentration will be output as an electrical signal.

A detector system based on mechanical components will be considered by OPTOLINK and it is possible that a combination of the detection methods will be used.

5.CONTROL SYSTEM For an incoming signal from the transducer the control circuit will decide which of the reference signal to use.

Upon receipt of this signal the oil will be released on to the burner.

The system will use microprocessor to monitor the sampling.

THE PROCESSOR SYSTEM This will consist of a controller for the sensor system giving a signal output to the processor, which will be selected under software control. The processor will be a type having a built in analogue to digital convertor, into which the selected sensor signal will be fed . The attached memory will contain the system program, and also a look-up table, containing data on parameters for a number of different atmospheres.

The sensor level will be compared with the optimum level as indicated by the selected data and decision on wether to release more essential oils into the atmosphere.

SCANNING PROCESS The interval between the each dispersion of essential oil to produce the required aroma shall not exceed 60 minutes.

Scanning will be in a max period of 3 minutes 6.POWER SOURCES The system may be powered from an external source of supply and may incorporate recharging facilities for any rechargeable batteries contained in the control part.

The external power cable must be separated . The requirement of any national safety standard will be observed such as BS 6301.
