A content transfer system includes a provider deviceand a receptor device, such as a personal digital assistant. The receptor deviceis arranged to monitor the activity or usage of the device, and determine or predict therefrom a period of low device activity. In such a low period of activity, content transfer control means, in the form of a controller, is arranged to initiate the transfer of an item of content from the provider deviceto the receptor device. The content may be secondary content such as text information from a television signal. Compression, decompression or other processor intensive tasks, such as preparing the content according to the output capabilities, may also be performed during times of low device activity.

Content delivery according to device activity

A memory card mounted in a general purpose ATA expansion memory location in a separate electronic device, such as a high-class digital camera, includes a data communication feature for transmitting the memory contents to a mobile station. Expansion cards containing memory which can be written and read are called Compact Flash, in accordance with the Flash EEPROM memory contained in small-sized cards. The data communication is performed on a short-range, low power radio frequency (LPRF) link. The memory card is also applicable for instance in a personal digital PDA notebook, where the input data can be stored in an expansion memory. The duplex feature of the expansion memory enables the data to be transmitted at a radio frequency to a mobile station. The data communication features of the wireless device are available for forwarding the data.

Method for data communication between a wireless device and an electric device, and a data communication device

A card-like wireless communication device including at least a frame part and an antenna structure, the antenna structure comprising an antenna part and fixing means for arranging the antenna part in connection with the frame part. The card-like wireless communication device also includes a first part and a second part, the parts being arranged to be movable in relation to each other in at least the longitudinal direction of the card-like wireless communication device. The first part is arranged as the frame part and the second part is arranged as the antenna part which can be moved in at least two different positions.

Card-like wireless communication device

An expansion card interface of an electronic device (,) in accordance with the invention comprises at least one expansion card connector (,) comprising a contact pin (V,, V,, V,, V,) for transferring a given signal. The electronic device (,) further comprises a power supply (,), such as a battery or a mains supply (,). A voltage (V,) of the power supply (,) of the electronic device can be connected to said contact pin (V,, V,, V,, V,) instead of said signal.

Electronic device, card interface and expansion card with transposition of signal and voltage lines

A method and system for the arrangement of a power supply with an expansion card which can be connected to an electronic device and comprises at least a first and a second circuit. The power supply is arranged in at least two stages, wherein at the first stage, at least one operating voltage (Vcc) is connected to the first circuit, and at the second stage, the at least one operating voltage (Vcc) is connected to the second circuit.

System and method for supplying power to an expansion card

The present invention relates to a terminal to be coupled to a telecommunications network using radio communication, which consists of a computer (100) and a radio module (200) to be coupled thereto. The radio module is connected to the computer using a digital bus coupling, for example a PCMCIA bus. This terminal can be connected to a telecommunications network using radio communication, for example, the GSM system. It is essential to the invention that the operations required in the transmission and reception of a message and their performance have been divided between the computer and the radio module. Two alternative embodiments are presented. In the first embodiment, the radio module contains ancillary processors (213, 214) to achieve a sufficient calculation capacity; in the second embodiment, the computer's processor (110) performs the main part of the required processing. The necessary radio frequency elements (230) are located in the radio module.
