Patent number: 5590401Abstract: A radio selective calling receiver including an exchangeable first battery and a second battery which can be charged by the first battery. A CPU stops operating at a stop voltage. A RAM stores a user data. A stop detector detects operational stop of the CPU. A power supply changer changes one of the first and second batteries into the other and selectively supplies one of electric energies of the batteries to the CPU, RAM and stop detector. The minimum operable voltages of the RAM and the stop detector are lower than the stop voltage. The first battery supplies its electric energy to the CPU, RAM and stop detector until the supply voltage of the first battery lowers to the stop voltage. The power supply changer changes the first battery into the second battery when the operational stop of the CPU is detected, so that the second battery supplies its electric energy to the CPU, RAM and stop detector until the first battery thus lowered in supply voltage is exchanged by a new one.Type: GrantFiled: April 18, 1994Date of Patent: December 31, 1996Assignee: NEC CorporationInventors: Motoki Ide, Hiroaki Shibayama

Patent number: 5493280Abstract: 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.Type: GrantFiled: October 22, 1993Date of Patent: February 20, 1996Assignee: NEC CorporationInventor: Hiroaki Shibayama

Patent number: 5332994Abstract: In a radio pager, a power-backup memory is provided for storing messages. On receiving a paging signal, a message contained in it is stored into the memory and the user is alerted with a first sound pattern. A specified label is attached to the stored message if it is not answered by the user within a prescribed interval. When the pager is turned off for battery savings purposes, the message is kept in the memory and when it is turned on again, the memory is searched. If a message attached with the specified label is detected, the user is alerted with a second sound pattern which is different from the first sound pattern. The different sound allows the user to quickly recognize that he is alerted by an uncompleted page.Type: GrantFiled: February 14, 1992Date of Patent: July 26, 1994Assignee: NEC CorporationInventors: Shinichi Kawashima, Hiroaki Shibayama
