Abstract
Locking devices, electronic locks, and detection assemblies are provided. One locking device includes an antenna and a conductive body having a cavity disposed around the antenna and formed in an interior portion of the conductive body. The conductive body further includes a slot extending from the cavity to an outer surface of the conductive body.
Claims21
A locking device comprising:
- an antenna;
- and
- a conductive body having a cavity disposed around the antenna and formed in an interior portion of the conductive body, wherein the conductive body further comprises a slot extending from the cavity to an outer surface of the conductive body;
- wherein the antenna is disposed about a non-conductive body, and wherein the conductive body has a complementary cross-section to a cross-section of the non-conductive body.

An electronic lock comprising:
- a lock assembly;
- a detection system associated with the lock assembly, the detection system comprising:
- a processing circuit, and
- a detection circuit having an antenna,
- wherein the detection system is operable to actuate the lock assembly in response to data from the processing circuit representative of an authorized access;
- and
- a body comprising:
- a conductive body disposed about the antenna, wherein the conductive body comprises a longitudinal slot extending along at least a portion of the conductive body, and
- a front conductive portion having a vertical slot, wherein the front conductive portion is in electrical communication with the conductive body and wherein the vertical slot and the longitudinal slot are substantially coplanar;
- wherein the antenna is disposed about a non-conductive body, and wherein the conductive body has a complementary cross-section to a cross-section of the non-conductive body.
7 more elements
A detection assembly comprising:
- a detection system comprising an antenna;
- and
- a body comprising:
- a conductive body disposed about the antenna, wherein the conductive body comprises a longitudinal slot extending along at least a portion of the conductive body, and
- a front conductive portion having a vertical slot, wherein the front conductive portion is in electrical communication with the conductive body and wherein the vertical slot and the longitudinal slot are substantially coplanar;
- wherein an RF current is generated about the vertical slot when the antenna disposed within the conductive body emits an RF signal;
- and
- wherein the antenna is disposed about a non-conductive body, and wherein the conductive body has a complementary cross-section to a cross-section of the non-conductive body.
5 more elements
An electronic lock comprising:
- a lock assembly;
- a detection system associated with the lock assembly, the detection system comprising an antenna, wherein the detection system is operable to detect at least one of an RFID and an NFC device, wherein the detection system is operable to actuate the lock assembly in response to a detection of at least one of an authorized RFID and an authorized NFC device;
- and
- a body comprising:
- a substantially cylindrical conductive body disposed about the antenna, wherein the substantially cylindrical conductive body comprises a longitudinal slot extending along at least a portion of the substantially cylindrical conductive body, and
- a front conductive portion having a vertical slot, wherein the front conductive portion is in electrical communication with the substantially cylindrical conductive body and wherein the vertical slot and the longitudinal slot are substantially coplanar,
- wherein the antenna and the at least one of the RFID device and NFC device are in communication via an RF current generated about the vertical slot;
- and
- wherein the antenna is disposed about a non-conductive body, and wherein the substantially cylindrical conductive body has a complementary cross-section to a cross-section of the non-conductive body.
