Abstract

A cordless telephone which includes a static RAM (50) for storing time management information and a real time clock (52). The time management information which includes telephone numbers and diary information is written into the static RAM (50) using a personal computer (PC) during recharging of the telephone'"'"'s batteries. In operation, the telephone'"'"'s microcontroller (40) compares the real time with entries stored in the static RAM (50) and when there is coincidence, an alert is given to the user. Alternatively data entered into the static RAM (50) by a user using a key pad (46) or derived from a received radio telephone link can be read-out to the PC when the batteries are being recharged.

Claims

1. A combination of a cordless telephone and a battery charging apparatus, wherein

said cordless telephone has a housing, and comprises within said housing a rechargeable battery, a microcontroller, a transceiving means, a keypad, display means, a real time clock and storage means for storing time management data;

and said cordless telephone has battery charging terminals in said housing, and

said battery charging apparatus has a casing having means for receiving the cordless telephone, and charger terminals for mating with said battery charging terminals when the cordless telephone is received by said means for receiving,

characterized in that the cordless telephone further comprises at least one input terminal on said housing adjacent to, but spaced from, said battery charging terminals, and means for transferring data in at least one direction between the storage means and said at least one input terminal,

said battery charging apparatus comprises at least one signal terminal disposed adjacent to, but spaced from, the charger terminals for mating with said at least one input terminal when the cordless telephone is received by said means for receiving, and means for connecting said at least one signal terminal to an external source to permit transfer of data in at least one direction between the storage means in the telephone and the external source while the battery is being charged, and

said microcontroller is operable, in response to inputs from a user through the keypad, to cause data in the storage means to be transferred to the external source via the at least one input terminal and the at least one signal terminal while the battery is being charged.

2. A combination as claimed in claim 1, characterized in that said means for connecting includes a data cable connection, and a buffer connected between the at least one signal terminal and the data cable connection.

3. A combination as in claim 1, characterized in that said microcontroller is operable, in response to signals from the external source, to cause time management data, received by the connecting means from the external source and transferred via the at least one signal terminal and the at least one input terminal, to be stored in the storage means while the battery is being charged.

4. A combination of a cordless telephone and a battery charging apparatus, wherein

said cordless telephone has a housing, and comprises within said housing a rechargeable battery, a microcontroller, a transceiving means, a keypad, display means, a real time clock and storage means for storing time management data;

and said cordless telephone has battery charging terminals on said housing, and

said battery charging apparatus has a casing having means for receiving the cordless telephone, and charger terminals for mating with said battery charging terminals when the cordless telephone is received by said means for receiving,

characterized in that the cordless telephone further comprises input terminals on said housing disposed adjacent to, but space from said battery charging terminals for conductively receiving signals from an external source to update the time management data stored in said storage means,

said battery charging apparatus comprises signal terminals disposed adjacent to, but spaced from, said charger terminals for conductively mating with said input terminals when the cordless telephone is received by said means for receiving, a personal computer interface, and means for connecting said signal terminals to an external personal computer via the personal computer interface to permit transfer of time management data in at least one direction between the storage means in the telephone and the external personal computer while the battery is being charged, and

said microcontroller is operable, in response to inputs from a user through the keypad, to cause data in the storage mean to be transferred to the external personal computer via the input terminals and the signal terminals while the battery is being charged.

5. A combination as claimed in claim 4, characterized in that said microcontroller is operable, in response to signals from the external personal computer, to cause time management data, received by the connecting means from the external personal computer and transferred via the signal terminals and the input terminals, to be stored in the storage means while the battery is being charged.

6. A cordless telephone having a housing, and comprising within said housing a microcontroller, a transceiving means, a keypad, display means, a real time clock, storage means for storing time management data, and a rechargeable battery;

and battery charging terminals on the housing for conductively mating with terminals in a battery charging apparatus,

characterized by further comprising input terminals on said housing, adjacent to but spaced from said battery charging terminals, for conductively receiving signals from an external source through mating terminals on the battery charging apparatus, to update the time management data stored in said storage means while the battery is being charged, and

said microcontroller is operable, in response to inputs from a user through the keypad, to cause data in the storage means to be transferred to the external source via the input terminals and the mating terminals on the battery charging apparatus while the battery is being charged.
