Low battery detection system
First Claim
1. A low battery voltage detection system in a hotel entertainment arrangement based on a network which extends from a central location to a plurality of remote locations with there being a central controller located at the central location for transmitting video information signals on the network to, and for communicating over the network to obtain information from, devices connected to the network at the remote locations, the low battery voltage detection system comprising:
- a plurality of guest terminals each connected to the network at one of the remote locations and each having a video display to present information provided by the video information signals received over the network from the central controller, and each being capable of receiving signals generated at said remote location thereof;
a plurality of battery operated transmitters each corresponding to one of the plurality of guest terminals for transmitting signals thereto that in part control the video information presented on the video display of the corresponding guest terminal, and each having a battery and a voltage detector for detecting a battery voltage value therein, each battery operated transmitter being capable of transmitting battery status information based on battery voltage values detected by the voltage detector therein to its corresponding guest terminal to be stored therein and to be obtainable by the central controller communicating with that guest terminal over the network; and
a list displayer located at the central location under control of the central controller, the list displayer for providing a list of transmitters having a selected voltage status.

Abstract
A low battery detection system for detecting the battery voltage level in a remote control unit of a hotel entertainment system comprises a detection circuit imbedded within the remote control unit. Information regarding the battery voltage status is transmitted to a guest television terminal along with the infrared signal which turns the television on or off. A central computer polls each guest television terminal associated with an individual guest room to determine whether the battery in the remote control unit needs to be replaced. A system for generating a list of remote control units identified by guest room, which needs fresh batteries is also provided. In this manner, hotel personnel can detect and replace batteries in remote control units which are prone to impending battery failure without guest complaints. Further, the parameters which determine whether a battery needs to be replaced can be altered by the user of the system.
