Power consumption of an electronic device is measured by using circuitry within the electronic device to make power consumption measurements of the electronic device at predetermined time intervals. Each of the power consumption measurements is provided to a user of the device. This may involve incorporating each of the power consumption measurements in a debug printout generated by the electronic device. The measurements may be initiated by retrieving a parameter from a storage area within the electronic device, and initiating the power consumption measuring techniques in response to detecting that the retrieved parameter is in a predetermined state.

Power consumption debugging in mobile terminals

A portable communication device for conference calls, comprising at least first and second speech encoder paths with first and second inputs for connection to first and second recording devices, respectively, and at least one output connected to signal processor means for receiving and processing first and second electronic signals from said recording devices via said first and second speech encoder paths for transmission to a transmitter/receiver operatively connected to said signal processor means, wherein said apparatus is adpated to receive said first and second electronic signals simultaneously even if the signals are different, and said apparatus comprises a summator adapted to sum said first and second electronic signals into a sum signal for transmission to said transmitter/receiver.

Portable communication device

A method for determining usage time for a plurality of modes of a mobile device wherein a self learning table within the mobile device includes a plurality of storage locations for storing current usage values and each of the storage locations has an association with a zparticular mode of the terminal. Additional storage locations may be added to the table responsive to new modes of operation of the mobile device,

Self learning system and method for predicting remaining usage time for different modes of a mobile device

The present invention relates to a device for connecting two electrical circuits (2,17;15,16) by a connection which permits that the two circuits easily can be separated and reunited again at the same time as interference and scratching noise in the connection mechanism are avoided. A first carrier (14, 28) is movable around a shaft (1), which is fastened onto a second carrier (7, 29). The first carrier (14, 28) can easily be removed from the shaft (1) and refitted again. The first carrier (14, 28) has a projecting part (8, 23, 30), which presses against an electrically conducting elastomer (4,18a-l, 21, 33) localized on the second carrier (7, 29). On the projecting part (8, 23, 30) there is an electrically conducting part (9, 20a-l, 24a-h), which is connected to a first electrical circuit (2,17) localized on the first carrier (14, 28). The electrically conducting elastomer (4,18a-l, 21, 33) is connected to a second electrical circuit (15,16) localized on the second carrier (7, 29). By means of co-operation between the projecting part (8, 23, 30) and the elastomer (4,18a-l, 21,33), an electrical connection between the first (2,17) and the second circuit (15,16) is achieved.
