Avoiding NFC communication collisions between accessories and user equipment
First Claim
1. An accessory for a user equipment, the accessory comprising:
- a housing that is slid on the user equipment to become attached in a stored position relative to the user equipment; and
a near field communication (NFC) circuit attached at a location on the housing and configured to become powered by inductive coupling to signals emitted by another NFC circuit within the user equipment to temporarily operate to transmit data to the other NFC circuit within the user equipment as the NFC circuit passes over the other NFC circuit while the housing is being slid on the user equipment before reaching the stored position relative to the user equipment,wherein while the housing is in the stored position relative to the user equipment, the NFC circuit is inhibited from transmitting data to the other NFC circuit within the user equipment irrespective of whether the other NFC circuit is emitting signals to attempt to provide inductive coupling to the NFC circuit.

Abstract
An accessory for a user equipment (UE) includes a housing and a near field communication (NFC) circuit. The housing is slid on the UE to become attached in a stored position relative to the UE. The NFC circuit is attached at a location on the housing and configured to become powered by inductive coupling to signals emitted by another NFC circuit within the UE to temporarily operate to transmit data to the other NFC circuit within the UE as the accessory NFC circuit passes over the other UE NFC circuit while the housing is being slid on the UE before reaching the stored position relative to the UE. While the housing is in the stored position relative to the UE, the NFC circuit may be configured to be inhibited from transmitting data to the other NFC circuit within the UE irrespective of whether the other NFC circuit within the UE is emitting signals to attempt to provide inductive coupling to the NFC circuit.

11. An accessory for a user equipment, the accessory comprising:
-
a housing that is slid on the user equipment to become attached in a stored position relative to the user equipment; and a near field communication (NFC) circuit attached at a location on the housing and configured to become powered by inductive coupling to signals emitted by another NFC circuit within the user equipment to temporarily operate to transmit data to the other NFC circuit within the user equipment as the NFC circuit passes over the other NFC circuit while the housing is being slid on the user equipment before reaching the stored position relative to the user equipment, wherein the NFC circuit comprises; a pair of antennas, each antenna is configured to be inductively coupled to the other NFC circuit within the user equipment; a transceiver configured to be powered by at least one of the pair of antennas to operate to transmit data through at least one of the pair of antennas to the other NFC circuit within the user equipment; and a signal comparator and charging circuit connected to the pair of antennas and configured to prevent the transceiver from transmitting data to the other NFC circuit within the user equipment until subsequently triggering the transceiver to transmit data to the other NFC circuit based on comparison of relative levels of signals from the pair of antennas. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An accessory for a user equipment, the accessory comprising:
-
a housing that is slid on the user equipment to become attached in a stored position relative to the user equipment; a near field communication (NFC) circuit attached at a location on the housing and configured to become powered by inductive coupling to signals emitted by another NFC circuit within the user equipment to temporarily operate to transmit data to the other NFC circuit within the user equipment as the NFC circuit passes over the other NFC circuit while the housing is being slid on the user equipment before reaching the stored position relative to the user equipment; and a conductive signal shield attached at a location on the housing that is between the NFC circuit and the other NFC circuit within the user equipment while the housing is in the stored position relative to the user equipment to decrease inductive coupling of the NFC circuit to signals emitted by the other NFC circuit and substantially prevent the NFC circuit from transmitting data while the housing is in the stored position relative to the user equipment. - View Dependent Claims (19, 20)
