  • the remote control device enters its full power mode of operation upon request from the controllable device (television, or the like).
  • the remote control device then transmits its location to the controllable device for display etc. to the user.
  • the remote control device since the remote control device must be on standby to detect the request from the controllable device, it requires some power consumption and cannot utilise a sleep mode. In its relatively low power standby mode of operation, the device still drains the batteries to some extent and power consumption is not minimised prolonging life of the batteries.
  • the user has to wait for the location of the remote control device to be detected and transmitted to the controllable device. Further, upon issue of the request from the controllable device, the portable device may be out of range and consequently cannot be located.
  • the present invention seeks to provide a locator for a portable device, the portable device having a sleep mode and an awake mode to reduce power consumption whilst enabling tracking of the location of the portable device.
  • a method for locating a portable device the portable device in wireless communication with a host device and operable in a sleep mode and an awake mode, the method comprising the steps of: determining the location of the portable device at predetermined time intervals during the awake mode; transmitting the determined location to the host device at the predetermined time intervals; and retrieving the last transmitted location as the current location of the portable device.
  • the location of the portable device is tracked and the last known location of the portable device is retrieved and indicated to the user, that is, up to date location data is available irrespective of when the user requests such information.
  • the location is determined and transmitted during the awake mode of operation, the power consumption of the device is greatly reduced.
  • the last transmitted location may be retrieved upon a request made at the host device.
  • the current location can then be conveyed to the user by, for example, display on the host device, or verbally.

  • the portable device may be a mobile telephone or PDA and the host a personal computer, car etc.
  • the portable device 101 is a handheld device powered by batteries and the host device 103 is generally in a fixed location.
  • the portable device 101 comprises a motion sensor 105, for example, a three axis motion sensor.
  • the motion sensor 105 can be reset such that all the axises are zero when the portable device 101 is placed on top of the host device 103.
  • the location of the portable device 101 is then given relative to the host device.
  • the motion sensor 105 is connected to a processor 109.
  • the processor 109 calculates the relative location of the portable device 103 relative to the host device 103 on the basis of the output of the motion sensor 105.
  • the portable device 101 also comprises a temporary store 111 connected to the processor 109 for storing the determined location of the portable device calculated by the processor 109 prior to transmission to the host device.
  • the portable device 101 comprises a timer (or counter) 113 connected to the processor 109, a transceiver 115 connected to the processor 109 and a power controller 117 connected to the processor 109.
  • the portable device 101 also comprises a power source, for example, a battery or rechargeable battery, not shown here, which provides power to all of the elements of the portable device 101 and is controlled by the power controller 117.
  • the host device 103 comprises a user control panel 119 which comprises a plurality of push buttons providing additional, manual control of the operation of the host device 103.

  • the sleep state the portable device 101 operates at an extremely reduced power consumption, for example, less than 10 niA. For example, to maintain power to the motion sensor only, approximately 500 ⁇ A is used. This greatly reduces the power consumption of the power source and prolongs the life of the batteries.
  • the timer 113 may be incremented to maintain an account of time elapsed in the sleep state.
  • the motion sensor 105 is also maintained.
  • the motion sensor 105 of the portable device 101 detects movement of the portable device 101, it sends an indication to the processor 109 which sends a command to the power controller to 'wake up' the device 101 so that the device operates at full power consumption, steps 203 and 205.
  • the portable device 101 is placed in 'wake up' state if a predetermined time interval has elapsed as indicated by the timer 113.
  • the location of the portable device 101 is calculated by the processor 109 on the basis of the output of the motion sensor 105, step 207. As mentioned above, the location may be determined relative to the position of the host device 103.
  • the location data is temporarily stored in the store 111 and transferred to the transceiver 115 to be transmitted via a wireless communication to the receiver 123 of the host device 121, step 209.
  • the location of the portable device 101 is determined and transmitted to the host device 103 at predetermined time intervals 211 whilst the portable device 101 is in its awake state, step 213.
  • the data Upon receipt of the location data, the data is stored in a memory store 127 of the host device 103.
  • the data may be stored such that only the last transmitted data is stored as the "current" location.
  • the current location is then retrieved when requested by the user, via the control panel 119, and displayed or indicated to the user via the output rendering device 125.

  • the portable device 101 may be "woken up” by detection of movement by the motion sensor 105 and/or the portable device is “woken up” after a predetermined time has elapsed.
  • the host device 103 therefore, receives regular updated location data so that the host device 103 can track the location of the portable device 101 and upon request from the user, can indicate to the user the last known position of the portable device 101.
  • the transmission of the location data is triggered when the device enters its "wakeup" mode which is triggered by movement of the portable device 101 or time out and then subsequently updated at predetermined time intervals whilst the device is in its awake state.
  • the portable device may be triggered by lapse of a time interval and/or by detection of movement to enter its wake up state.
  • the portable device may comprise a locator connected to the processor 109.
  • the locator and processor 109 calculate the location of the remote control device.
