Drawings Figure I shows a top view or a temperature monitor according to the present invention; Figure 2 shows a front view of the temperature monitor of Figure 1 with the outer housing removed so that the internal layout is visible; Figure 3 shows a rear view of the temperature monitor of Figure 1 with the outer housing and overlying internal components removed so that the internal layout is visible; and Figure 4 shows a rear view of the temperature monitor of Figure 1 with the outer housing removed so that the overlying internal components are visible.
With reference to Figures 1 to 4, a portable temperature monitor includes a plastics outer housing 2 incorporating a graphic overlay 4 that covers a board-mounted liquid crystal display (LCD) 6, user-operable switches (tact switches) Ba-Se and light emitting diodes (LEDs) lOa-lOf. The graphic overlay 4 includes areas 12a-12d overlying the uscr-opcrable switches Ba-Se and graphic indicators 14a-14f overlying the LEDs lOa-lOf to indicate certain operational modes or conditions of the temperature monitor. For example, indicator 14a indicates low signal strength, indicator 14b indicates low battery, indicators 14c and 14d indicate the selected temperature unit (e.g. °C or °F), and indicators 14e and 14f indicate if the upper or lower temperature setpoint is being programmed or exceeded. The LEDs I Oa-lOf can be controlled to turn on and off to light up the overlying indictor and can change colour (e.g. from green to red or vice versa) and/or flash on or off depending on the operational mode of the temperature monitor.
The outer housing 2 also encloses a temperature sensor 16, a user-programmable processor unit 18 mounted on the printed circuit board (PCB), a temperature select switch 20 that can adjust the temperature units between Celsius and Fahrenheit, a mobile phone module 22 including a holder 24 which is capable of receiving a subscriber identity module (SIM) card, a connector 26 to allow the temperature monitor to be connected to an external temperature sensor (not shown), a connector 28 to allow the temperature rnonitor to be connected to an external power supply or battery charger (not shown), a rechargeable battery 30, and an internal aerial (radio antenna) 32 For the mobile phone module. The internal components may be accessed by removing the back of the outer housing.
The temperature monitor is used as follows: I. Setting up When the temperature monitor is used for the first time then a SIM card is inserted into the card holder 24 of the mobile telephone module 22. Any short message service (SMS) text messagcs or telephone calls made to the temperature monitor will be made to the mobile telephone number associated with the Silvi card.
The nominated mobile telephone number is programmed into the temperature monitor. This may be done by transmitting a SMS text message from a mobile telephone (or other portable electronic device) to the temperature monitor, optionally including a code that is unique to the temperature monitor. The temperature monitor will then transmit all signals whether SMS text messages, telephone calls, or other data transfers, to the nominated mobile telephone number.
The nominated mobile telephone number programmed into the temperature monitor can be changed by transmitting a SMS text message from a different mobile telephone (or other portable electronic device), optionally using the unique code. In some embodiments the temperature monitor can be programmed with two or more nominated mobile telephone numbers.
2. Switching on The region 12d overlying the switch Sc (the OniOff key') is pressed and held for a certain amount of time, e.g. 3 seconds, to turn the temperature monitor on. All of the LCD screen segments may flash and the LEDs ba-i Oc may be tumed on for a certain amount of time, e.g. I second.
The LCD screen 6 will display the current temperature in either Celsius or Fahrenheit depending on the position of the temperature select switch 20, and optionally also the battery level and signal level, i.e. the strength of the mobile telephone signal.
3. Setting the upper and lower temperature setpoints The region 12a overlying the switch Sa (the Edit' key) is pressed once to allow the user to set the upper temperature setpoint. The LED 1 Qe underneath the upper temperature setpoint indicator I 4e flashes to show that the user is editing the upper temperature setpoint and the LCD screen 6 shows the upper temperature setpoint that is currently programmed. The region I 2b overlying the switches 8b, 8c (the Up/Down' key) is pressed to adjust the upper temperature setpoint and the new upper temperature setpoint is shown on the LCD screen 6.
It will normally be possible to set the upper temperature setpoint to be below the current ambient temperature but the LED lOe underneath the upper temperature setpoint indicator 14e may change colour (e.g. from green to red) to inform the user.
Once the desired upper temperature setpoint has been reached, the region 12c overlying the switch Sd (the Set' key) is pressed to program the upper temperature setpoint and store it in the processor unit 18.
Once the upper temperature setpoint has been programmed, the user can set the lower temperature setpoint in a similar manner. The LED lOf underneath the lower temperature setpoint indicator 14f flashes to show that the user is editing the lower temperature setpoint and the LCD screen 6 shows the lower temperature setpoint that is currently programmed. The Up/Down' key is pressed to adjust the lower temperature setpoint and the new lower temperature setpoint is shown on the LCD screen 6.
It will normally be possible to set the lower temperature setpoint to be above the current ambient temperature but the LED tOf underneath the lower temperature setpoint indicator I 4f may change colour (e.g. from green to red) to inform the user.
Once the desired lower temperature setpoint has bccn reached, the Set' key is pressed is program the lower temperature setpoint and store it in the processor unit 18.
The upper and lower temperature setpoints may be varied in predetermined intervals, e.g. 0.5 °C or 1 °F each time the Up/Down' key is pressed.
It will be readily appreciated that an alternative option is for the lower temperature setpoint to be set before the upper temperature setpoint. Other ways of setting the upper and lower temperature setpoints are also possible.
If the upper temperature setpoint is programmed below the ambient temperature or the lower temperature setpoint is programmed above the ambient temperature then the temperature monitor will transition to the alann mode described in more detail after a certain delay, e.g. 2 minutes.
It will not normally be possible to set the lower temperature setpoint above the upper temperature setpoint or vice versa.
4. Normal mode During use the processor unit 18 will continuously compare the ambient temperature as detected by the temperature sensor 16 (or an external temperature sensor if connected) against the upper and lower temperature setpoints. The battery level is also monitored. The temperature monitor can be used to measure an outside temperature or the temperature within a space such as a motor vehic'e or the room of a house, for example. The temperature monitor will be particularly useflul for situations where an animal, and most typically a dog, is left inside a motor vehicle while the owner is absent, but it can be used in many other situations where temperature needs to be monitored From a remote location.
The temperature monitor will respond to any incoming demand signals as described in more detail below.
The LED lOa underneath the low signal strength indicator 14a can be made to flash if the strength of the mobile phone signal falls below a certain level.
5. Alarm mode There are three situations in which the temperature monitor will transition to the alarm mode, namely: * If the ambient temperature reaches or rises above the upper temperature setpoint * If the ambient temperature reaches or falls below the lower temperature setpoint * If a low battery condition is detected In alarm mode the temperature monitor will automatically transmit an alarm signal, preferably a SMS text message, to a nominated mobile telephone number.
For a temperature alarm then the SMS text message will include the current temperature in either Celsius or Fahrenheit depending on the position of the temperature select switch 20 together with a suitable warning, which may state that the upper or lower temperature setpoint has been reached or exceeded: WARNTNG! Current temperature ??00 -high temperature limit exceeded The ambient temperature displayed on the LCD screen 6 can be made to flash and the LED lOe, lOf underneath the respective upper and lower temperature setpoint indicator 14e, 14f may also flash or change colour.
If the ambient temperature remains at or above the upper temperature setpoint or remains at or below the lower temperature setpoint then the temperature monitor can continue to automatically transmit an alarm signal to the nominated mobile telephone number at a certain interval, e.g. every 2 minutes.
An alarm signal can also be automatically sent to the nominated mobile telephone number each time the ambient temperature increases or decreases by a certain amount, e.g. I °C or 2 °F.
If the ambient temperature falls below the upper temperature setpoint or rises above the lower temperature setpoint then the temperature monitor will return to the normal mode. A signal can be automatically sent to the nominated mobile telephone number to inform the user that the temperature monitor is no longer in the alarm mode.
The temperature monitor may provide an audible alert while in the alann mode.
For a low battery alarm then the SMS text message will include a suitable waming.
The LED lOb underneath the low battery indicator l4b may be made to flash: WARNTNG! Low battery detected 6. Switching off The OniOff key' is pressed and held for a certain amount of time, e.g. 3 seconds, to turn the temperature monitor off. The LCD screen 6 and LEDs lOa-lOf are turned off and the temperature monitor goes into a sleep mode.
7. Reporting on demand When the temperature monitor is in the normal mode it is possible to make the temperature monitor transmit a status signal, preferably a SMS text message, to the nominated mobile telephone number. The status signal will include the current temperature in either Celsius or Fahrenheit depending on the position of the temperature select switch 20.
The temperature monitor can be made to transmit the status signal by calling the temperature monitor or transmitting a SMS text message to the temperature monitor -10-from a mobile telephone (or other portable electronic device). If a call is made then the temperature monitor will recognise the incoming mobile telephone number and when the call is ended will then transmit a status signal to the nominated mobile telephone number. If a SMS text message is sent to the temperature monitor then it may optionally include a code to tell the temperature monitor to send the status signal.
Different codes may be used to control the temperature monitor remotely, and may even be used to program or vary the upper and lower temperature setpoints and control other operational thnctions.
The status signal can also include non-critical information such as battery level remaining, current signal strength, time switched on, and the upper and lower temperature setpoints, for example.
In an alternative version (not shown) the temperature monitor may include one or both of a microphone and a camera. It is possible to make the temperature monitor transmit a signal containing sound data provided by the microphone and/or image data provided by the camera to the nominated mobile telephone number. The user may then listen to the sounds detected by the microphone and/or view the images captured by the camera on their mobile telephone (or portable electronic device). The temperature monitor can be made to transmit the signal by calling the temperature monitor or transmitting a SMS text message to the temperature monitor from a mobile telephone (or other portable electronic device) as described above.
