Abstract
An electronic appliance lock can be used on televisions and other appliances for which use control is sought. In one embodiment, the lock sits atop a television set or is manufactured integrally with the television. In another embodiment the lock is made to plug directly into an electrical socket. Input and output are done by either keys and a display on the lock itself, or by using a remote control device and using the television screen as a display. The lock is capable of limiting use of the controlled appliance to either a fixed number of hours per preset allotment period, as well as blocking use during specified periods of time. In some embodiments access to one or more channels is regulated.
