Cellular telephone with keypad controller
First Claim
1. Cellular telephone apparatus having a plurality of operating modes and being operable on cellular radio channels, and cellular telephone apparatus comprising:
- a data bus having first and second ports;
a transceiver including a first microcomputer for controlling the operating modes and communicating cellular telephone calls on the cellular radio channels;
a controller having a plurality of keys including ten numerical keys for entering telephone numbers and including a memory key for controlling the operating modes of the cellular telephone apparatus;
a second microcomputer including a memory and being coupled to the controller for detecting activations of individual keys to receive telephone number digits and for detecting concurrent activations of predetermined key sequences to select a corresponding one of the operating modes, the predetermined key sequences including the memory key and another key, said second microcomputer storing each received digit in the memory, and said second microcomputer further being coupled to the first port of said data bus for automatically transmitting the stored digits or the selected one of the operating modes to the cellular transceiver when the elapsed time from detection of the last activated key exceeds a predetermined time interval; and
said first microcomputer coupled to the second port of said data bus for receiving the selected one of the operating modes and applying the received operating mode to the cellular transceiver, and receiving the transmitted digits and automatically transmitting the received digits on one of the cellular radio channels to originate a telephone call, whereby all dialed digits of each telephone number are automatically transmitted when dialing is interrupted for at least the predetermined time interval.

Abstract
A unique cellular telephone (500) includes audio circuit 502, microcomputer (508), indicators (506) and (507), cellular telephone transceiver (519), and keypad controller (504) for controlling the operating modes thereof and automatically placing and receiving cellular telephone calls dialed in any pattern. The keypad includes numerical keys (0-9, # and *) and function keys (MEM and END/CLEAR) for entering digits of telephone number and key sequences for selecting operating modes. Power is applied to the cellular telephone transceiver (519) in response to concurrent activation of at least two keys. Each telephone number digit is detected and accumulated by microcomputer (508) and, after a pause of four seconds, the accumulated digits are sent via a data bus (511) to cellular telephone transceiver (519) for placing a telephone call. The call is subsequently terminated when the END key is activated or an END command is received by the cellular telephone transceiver (519). Thereafter, power to the cellular telephone transceiver (519) may be turned off in response to activation of the MEM-END key sequence.
