Abstract: Arbitration of multiple transponders, such as RFID tags, occurs in an interrogation field. The arbitration process is custom-tailored for individual applications, under software control, by the transponder reader or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may send a special fast read command to the tag which includes a read request and communications control parameters including the number of time slots for transponder communications, the number of transmissions that an individual transponder is allowed to issue, and the data rate at which the reader communicates to the transponder. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment.

Abstract: A schedule recording section (4) records a user's schedule. A SOC (state-of-charge) optimization planning section (5) plans the SOC of a rechargeable battery (21) based on the user's schedule. The planned control target SOC is optimized through a comparison between the continuous charging characteristic of the rechargeable battery (21) and the length of an operable period or the amount of electric power to be secured at the time of battery-powered operation. For example, a control target SOC is set at a full charge in the proximity of the period during which a battery-powered operation time is expected to be long. A control target SOC is set lower enough than a full charge in the period during which a connection to an external power supply (A) by the AC adapter (11) is expected to continue for a long time. A power-supply control section (3) controls the charge and discharge of the rechargeable battery (21) according to a plan for the optimization of the SOC.
