As a result of a user breathing on the alcohol sensor, a signal indicative of the amount of alcohol detected in the breath of the user is generated by the sensor. The signal is transferred to the processor in the mobile phone 12 which generates a value in response to the signal which is indicative of the amount of alcohol in the user's breath. The mobile phone 12 then interacts with the mobile communications network 26 to generate a location tag signal indicative of the jurisdiction in which the device is located. Using the communications means in the mobile phone 12, a request signal containing the location tag signal is sent from the mobile phone 12 through the interfacing means 22 to the database 20. The request signal is to the effect that the mobile phone 12 requires information as to the current maximum legal amount of alcohol permitted in breath for the jurisdiction in which the.mobile phone 12 is located. As a result of the request, the appropriate maximum legal alcohol amount is retrieved from the database and forwarded through the interfacing means 22 to the mobile phone 12. On receipt ■ of the retrieved maximum legal alcohol amount at the mobile phone 12 , the processor in the mobile phone 12 compares the alcohol amount value detected by the sensor with the maximum legal' alcohol amount retrieved from the database 20, and a determination is output to the user which indicates whether the alcohol amount detected by the sensor is above or below the maximum legal alcohol amount for the jurisdiction concerned. The information provided to the user may be in the form of a visual indication on a screen 31 or as an audible indication from a speaker 33. In addition to providing the user with an indication as to whether the amount of alcohol in the user's breath is above or below a maximum legal amount for the jurisdiction concerned, the breathalysing system 10 may be arranged so that the processor in the mobile phone 12 automatically transmits a signal indicative that the user requires transport when the sensed alcohol amount is above the retrieved maximum legal alcohol amount, as the user is not legally able to drive a vehicle. Such a signal may be directed to a remote transport station which may be a taxi company, and the signal may include information usable by a Global Positioning System (GPS) to automatically determine the location of the user.
An alternative embodiment of the breathalysing system is shown at 32 in Figure 2. Like or similar features are indicated with like reference numerals.
The embodiment shown in Figure 2 is essentially the same as the embodiment shown in Figure 1 in that the breathalysing system 32 includes a mobile device 12, 14, 16, 18 having an alcohol sensor and a processor, a database 20, and interfacing means 22 for facilitating wireless communication between the mobile device 12, 14, 16, 18 and the database 20. However, with this embodiment, instead of providing the interfacing means 22 with a mobile communications network 26, the Internet 24 and two interfaces 28, 30 to facilitate wireless communication, only a mobile communications network 26 and a single interface 34 are provided. It will be understood, however, that this embodiment of a breathalysing system essentially operates in the same way as the embodiment shown in Figure 1.
The interface 34 may be any interface suitable for converting signals received from the mobile communications network 26 into signals receivable by the database 20 and vice versa.
In Figure 3, there is shown a further alternative embodiment of a breathalysing system 36. This embodiment is similar to the embodiment shown in Figures 1 and 2 except that a processor 38 is provided at a remote location which may be the same as or different to the remote location at which the database 20 located.
With this embodiment, after generation of a signal by the alcohol sensor indicative of the amount of alcohol detected in a user's breath, the signal is transmitted using the communications means, in the mobile device 12, 14, 16, 18 and the interfacing means 22 to the processor 38. Once received by the processor 38, the signal is converted to a value indicative of the amount of alcohol in the user's breath. , The mobile device then interacts with the mobile communications network 26 to generate a location tag signal indicative of the jurisdiction in which the device is located. The mobile device also transmits a request signal containing the tag signal to the database 20 for retrieval of a value from the database 20 for the maximum legal alcohol amount in breath for the jurisdiction in which the mobile device 12, 14, 16, 18 is located. Once the appropriate maximum legal amount has been retrieved from the database 20, the maximum legal amount for the jurisdiction concerned is transferred from the- database 20 through the interface 34 to the processor 38 where the maximum legal amount is compared with the detected alcohol amount value. A determination as to whether the detected alcohol amount value is above or below the maximum legal amount is then transferred from the processor 38 through the interfacing means 22 to the mobile device, 12, 14, 16, 18 where an indication is provided to the user as to whether the detected alcohol amount is above or below the maximum legal amount.
Although with this embodiment both conversion of the signal from the alcohol sensor to a value indicative of an alcohol amount and comparison of the detected alcohol amount with the maximum legal amount for the jurisdiction concerned is carried out by the processor 38 at the remote location, it will of course be understood that an appropriate processor may also be provided in the mobile device 12, 14, 16, 18 and either of these processes may be carried out in the mobile device. In this way, the necessary signal processing may be shared between the processor in the mobile- device 12, 14, 16, 18 and the processor 38 at the remote location. The important aspect is that appropriate processing is provided for manipulating and interpreting signals from the mobile device 12, 14, 16, 18 and the database 20 so as to generate an alcohol amount value, to compare the maximum legal alcohol amount with the detected alcohol amount value, and to provide a- determination as to whether the detected alcohol amount is above or below the maximum •legal amount .
As a further alternative embodiment, the mobile device may include a local database, the local database being arranged to store information relating to the maximum legal amount of alcohol in breath for a plurality of jurisdictions.
With this embodiment, instead of sending a request signal from the mobile device 12, 14, 16, 18 to the remote database 20 each time the user breathes on the alcohol sensor, a request signal is sent to the local database.
In order to maintain the information in the local database up to date, a refresh signal containing updated maximum legal alcohol amount information is periodically sent from the remote database 20 to the local database. In this way, the local database can be used instead of the remote database 20 to provide the maximum legal alcohol amount for comparison purposes instead of the remote database 20. It will be appreciated that instead of utilising an interfacing means in the form of a wireless communications network and associated interfaces, the interfacing means may take the form of a data carrier which is arranged to physically connect with the mobile device. With this arrangement, the data carrier would hold a master database containing current maximum legal alcohol amount information, and the interfacing means would facilitate transferral of the information stored in the data carrier to the local database when the data carrier is connected to the mobile device.
It will also be appreciated that other embodiments are possible, such as a mobile device having a local database as described above and, instead of providing the mobile device with wireless communications means, the communications means of the mobile device may include a user interface or facilitate connection to a user interface. Such a user interface may be a keypad for facilitating manual entering of updated maximum legal alcohol amount information into the local database by a user.
It will also be appreciated that although the above described embodiments have been described in relation to a mobile device which generates a location tag signal by interacting with a communications network, other arrangements are possible within the scope of the present invention. For example, the mobile device may be arranged to receive location information directly from a user by providing an appropriate user interface.
It will also be appreciated that an important aspect of the invention is the provision of a mobile computing device which is arranged to carry out a plurality of functions, such as word processing, diary recording, web browsing and so on, and which is also able to carry out a breathalysing function using processing means of the computing device.
Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
