Abstract
A radio paging receiver enables an user of the receiver later to see a received message even when an alert stopping operation or message confirmation operation is first executed in an environment too dark to see the received message. The receiver has a photosensor for detecting whether a display environment is light or dark. If the alert stopping operation is executed in the dark condition, the received message is stored in a memory as an unconfirmed message, so that the user later can see and read the received message in a light condition after a change of the environment. In addition, when the environment is changed from a dark condition to a light condition, if an unconfirmed message exists in the memory, the receiver alerts the user.
Claims12
A radio paging receiver comprising:
- receiving means for receiving a radio signal containing a message signal;
- first light/dark detecting means for detecting whether a message display environment is light or dark;
- alert control means for generating an alert signal when the receiver is paged by a received radio signal;
- alerting means, responsive to the alert signal, for generating an alert for a user of the receiver;
- alert stopping means for stopping an alert generated by the alerting means, when an alert stopping operation is executed by the user during the alert;
- and
- message storing means for storing, if said light/dark detecting means detects a dark condition when the alert stopping operation executed, the received message in a memory as an unconfirmed message having not been confirmed by the user.
A radio paging receiver comprising:
- alerting means for reporting the presence of a received message;
- message distinguishing means for determining whether a received message has been confirmed by an operation of an user of the receiver;
- light/dark detecting means for determining whether a message display environment is light or dark;
- and
- message storing means for storing, if said light/dark detecting means detects a dark condition when the operation for confirming the received message is executed, the received message in a memory as an unconfirmed message having not been confirmed.
A method for controlling a radio paging receiver, the method comprising the steps of:
- (a) receiving a message to be displayed at the receiver;
- (b) alerting an user of the receiver of said receiving;
- (c) detecting an operation for stopping said alerting;
- (d) detecting whether a message display environment is light or dark at the time of execution of step (c);
- (e) displaying the received message if a light condition is detected in step (d);
- and
- (f) storing the received message as an unconfirmed message in a memory if a dark condition is detected in step (d).
A radio paging receiver comprising:
- light/dark detecting means for detecting whether a message display environment is light or dark;
- and
- generating means for generating a signal when the light/dark detecting means detects a change from a dark display environment to a light display environment and a message unconfirmed by a user has been stored in a memory.
