Abstract: A system for measuring the blood glucose level in a sample of a patient's blood. Consumable test strips (5) are provided together with a code (7) which identifies the manufacturing batch of the strip (5). A measurement unit (2) is provided and is coupled to a mobile telephone (1). The measurement unit (2) is arranged to receive a test strip (5) and to determine a color change in a reagent (4) due to reaction of the reagent (4) with a blood sample. The identification code (7) is read at the same time by the measurement unit (3) and is transmitted by the mobile telephone (1) to a central database (9) provided by the test strip manufacturer. The database (9) contains identification codes (7) together with associated calibration data. Upon receipt of an identification code (7), the remote database (9) transmits the associated calibration data to the mobile telephone (1) which uses the calibration data to calculate a test result from the measured change in color.

Abstract: A cellular radio system includes a unit for controlling payment traffic and a terminal equipment which can be used as a pay telephone in the cellular radio system. The terminal equipment includes a control unit connected directly to the cellular transceiver without a two-wire connection and a collecting means, for controlling collection operations, connected the control unit. The payment traffic is transmitted from the terminal equipment to unit for controlling payment traffic as short data messages over the cellular radio system. The terminal equipment further includes a hands free facility.

Abstract: The present invention relates to a method for controlling an accessory of a location data maintaining subscriber terminal equipment (204) of a cellular network and an accessory (214), and which comprises memory (202, 210) for maintaining a specified subscriber identifier differing from the identifier of the subscriber terminal equipment, and circuitry (206) for connecting to the terminal equipment.

Abstract: A method for interpreting digits of a sequence transmitted to a radio transceiver receives at least first, second and third digits of a sequence having at least first and second intervals respectively between the digits, waits for a new digit after receiving the third digit for a waiting time, interprets the digits at an end of the waiting time, and thereafter gives a command for a radio transceiver to transmit the digits. The waiting time is determined during the sequence from at least one characteristic of each of the intervals.
