System comprising a portable electronic device with a time function
First Claim
1. A system comprising a portable electronic device and an auxiliary device, the portable electronic device and the auxiliary device each comprising an interface allowing the establishment of a communication link between them, at least to be able to transmit data representative of a status information from the auxiliary device to the portable electronic device, wherein the portable electronic device comprises a timing unit for determining a time interval and a memory for storing data, wherein a reference start time is stored, and the portable electronic device is further adapted for monitoring and storing an operating time from a power-on-time to a power-off-time of operation of the portable electronic device, and wherein the auxiliary device comprises a master timing unit for providing a signal representative of the present time, and wherein the system is adapted to transfer said signal representative of the present time from the auxiliary device to the portable electronic device and to store it in said memory when the portable electronic device is connected to the auxiliary device or at the request of a user, whereby the daily use and non-use pattern of the portable electronic device can be estimated the portable electronic device including a measure of the absolute time elapsed from said reference start time.

Abstract
A portable electronic device and an auxiliary device each having an interface allowing the establishment of a communication link between them, at least to be able to transmit data representative of a status information from the auxiliary device to the portable electronic device, and-a method of of establishing a measure of an absolute elapsed time in a listening device. The problem is solved in that the portable electronic device has a timing unit for determining a time interval and a memory for storing data, and wherein the auxiliary device has a master timing unit for providing a signal representative of the present time, and wherein the system is adapted to transfer a signal representative of the present time from the auxiliary device to the portable electronic device and to store it in the memory.

15. A method of establishing a measure of an absolute elapsed time in a portable electronic device, the portable electronic device forming part of a system comprising the portable electronic device and an auxiliary device, the portable electronic device and the auxiliary device each comprising an interface allowing the establishment of a communication link between them, at least to be able to transmit data representative of a status information from the auxiliary device to the portable electronic device, the method comprising
storing a reference start time in the portable electronic device; -
providing in the auxiliary device a signal representative of the present time; transmitting said signal representative of the present time to the portable electronic device; receiving said signal representative of the present time in the portable electronic device when the portable electronic device is connected to the auxiliary device or at the request of a user; extracting and storing data representative of the present time in the portable electronic device; monitoring and storing an operating time from a power-on-time to a power-off-time of operation of the portable electronic device; determining in the portable electronic device an absolute time interval based on said data representative of the present time received from the auxiliary device and/or said reference start time, including the determination of a measure of the absolute time elapsed from said reference start time. - View Dependent Claims (16, 17, 18, 19, 20)
