System and method for detecting the removal of a controlling device
First Claim
1. A method for using a controllable appliance to determine an inoperable state of a controlling device, the method comprising:
- using a timer of the controllable appliance to measure a first plurality of timed intervals each having a first predetermined duration;
causing the controllable appliance to determine if a wireless notification signal has been received from the controlling device during each of the first plurality of timed intervals; and
when the wireless notification signal has not been received from the controlling device during at least one of the first plurality of timed intervals, causing the controllable appliance to issue a status notification that the controlling device is in an inoperable state.

Abstract
A system and method for using a controllable appliance to report an inoperable state of a controlling device. The appliance is caused to repeatedly determine, at a first predetermined timed interval, if a wireless notification signal, repeatedly transmitted by the controlling device at a second predetermined timed interval, has been received from the controlling device. When the wireless notification signal has not been received from the controlling device within the first predetermined timed interval, the appliance is caused to issue a status notification that the controlling device is in an inoperable state.

9. A system, comprising:
-
a controllable appliance having a first timer, wherein the first timer is used to measure a first plurality of timed intervals each having a first predetermined duration; and a controlling device having a second timer, wherein the second timer is used to measure a second plurality of timed intervals each having a second predetermined duration, and code data for use in controlling functional operations of the controllable appliance; wherein the controlling device transmits to the controllable appliance a wireless notification signal at an expiration of each of the second plurality of timed intervals and wherein the controllable appliance determines if the wireless notification signal has been received from the controlling device during each of the first plurality of timed intervals and, when the wireless notification signal has not been received from the controlling device during at least one of the first plurality of timed intervals, the controllable appliance is caused to issue a status notification that the controlling device is in an inoperable state. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method for using a set top box to determine an inoperable state of a controlling device, the method comprising:
-
using a timer of the controlling device to measure a first plurality of timed intervals each having a first predetermined duration; and causing the controlling device to repeatedly transmit a wireless notification signal to the set top box at an expiration of each of the first plurality of timed intervals whereby, in the event that the set top box determines that the wireless notification signal has not been received from the controlling device within at least one of a second plurality of timed intervals, wherein each of the second plurality of timed intervals is measured by use of a timer of the controllable device and wherein each of the second plurality of timed intervals has a second predetermined duration that is longer than the first predetermined duration, the set top box will determine that the controlling device is in an inoperable state. - View Dependent Claims (19, 20, 21, 22, 23)
