Most electronic devices that use a remote control are constantly wasting energy “listening” for signals from the remote control, even when they are turned off. The problem is magnified with home entertainment centers which use multiple devices, all of which are accessible with a remote control. I’ve applied for a patent for a remote control holster which physically disconnects power to an entertainment system when not in use. Picking up the remote restores power to the system. Another variation on this concept is to incorporate a holster into portable electronics devices, such as iPod speakers, such that if the remote is in the holster the device will stop listening for signals from the remote. I’m currently waiting for the patent to be approved, but more information on this idea can be found on my website at BlackRemote.com.
