Abstract

A chemical alert system for generating an alarm is de-scribed including a portable electronic device, prefera-bly with telecommunication capabilities to allow for data and/or voice communication via private or public net-works, and at least one chemical sensor (12,21) integrat-ed with the housing (10) of the portable device and con-trolled by a chemical sensor processing unit (25,26), further comprising an alert discriminator (32) receiving input (314) based on measurements (311) of the chemical sensor (12,21) , performing a test (321,322) on the input (314) and based on an outcome of the test initiating the transfer(324) of measurements of the chemical sen-sor(12,21) to a remote processing facility (29,33).

CHEMICAL ALERT SYSTEM USING A PORTABLE DEVICE WITH INTEGRATED CHEMICAL SENSOR

ABSTRACT

A chemical alert system for generating an alarm is de- scribed including a portable electronic device, prefera- bly with telecommunication capabilities to allow for data and/or voice communication via private or public net- works, and at least one chemical sensor (12,21) integrat- ed with the housing (10) of the portable device and con- trolled by a chemical sensor processing unit (25,26), further comprising an alert discriminator (32) receiving input (314) based on measurements (311) of the chemical sensor (12,21) , performing a test (321,322) on the input (314) and based on an outcome of the test initiating the transfer(324) of measurements of the chemical sen- sor(12,21) to a remote processing facility (29,33).

FIELD OF THE INVENTION

          The present invention relates to system for generating an alert or action in response to a change in the chemical composition of the surroundings of a porta- ble electronic device such as a mobile phone, tablet and the like using a chemical sensor integrated within the housing of the device.

BACKGROUND OF THE INVENTION

          Portable or mobile devices originally intro- duced as mobile phones or electronic agendas become more and more ubiquitous. As the processing power of their internal processors grows and equally the bandwidth for communication with stationary processors, such portable devices take on more and more the role of multi-purpose tools available to consumers and specialist users alike.

          It has been recognized that portable devices can benefit from the presence of sensors capable of providing chemical analysis of materials brought into contact or the vicinity of the device. Whilst there are many possible applications for such sensors, it suffices to consider for example the analysis of air surrounding the portable device. Such an analysis can be useful for multiple purposes such as testing for hazardous gases, breath analysis for general medical purposes or driving fitness, and the like.

          It has been known to incorporate gas sensors into portable sensor devices, such as mobile phones or tablet computers. For example, humidity sensors have been incorporated into some smartphone devices. However, hu- midity (i.e. gaseous water in air) is only one gas that might be of interest to a user of this type of device. Therefore, there is a need to provide devices that allow to measure a larger selection of gases, such as alcohol, CO, benzene, or groups of gases, which can e.g. be clas- sified as certain smells or odours.

          In case such gases can cause a hazard or pose an otherwise relevant condition for the user, it is de- sirable to use portable devices with integrated chemical sensors to issue an alarm or a notification to its user, to the surrounding of the user or to a remote location or to trigger an automated response.
