Low battery remote display system
First Claim
1. A mobile telephone comprising:
- a control part, accepting commands from a user, and carrying out the commands by taking an action on the mobile telephone responsive to the commands;
a wireless communication part that communicates information indicative of the commands to a remote device;
a connection to a battery, operating said control part and said wireless communication part;
a battery monitor that monitors a charge level of the battery, wherein information indicative of said charge level of the battery is communicated to said remote device by said wireless communication part; and
a processing part that receives said charge level, detects a battery voltage lower than a specified amount as said charge level, and wherein said information indicative of said charge level comprises an indication that the battery voltage is lower than the specified amount, wherein said wireless communication part also receives information, wherein said wireless communication part sends said information indicative of the charge level multiple times until receiving an indication that the information has been received by the remote device, and wherein said wireless communication part also obtains a remaining time that the mobile telephone can operate and displays information on the display about a remaining time that the mobile telephone can operate.

Abstract
A mobile device, e.g. a remote control, that communicates with a remote device. The device is controlled by a battery providing power for electronic circuits and components contained within the hand held remote control device. A battery monitoring device measures the voltage of the battery. A memory device saves the data generated by the battery monitoring device indicating the voltage of the battery. A transmission device transmits a notification to the display device when the voltage of the battery decreases to some predetermined level. The display device may receive the notification of a low battery from the hand held device. An application contained within the display device or the remote control displays a visual indication on the display device to the user indicating that the battery in the hand held device is low and requires recharging.
