Spindle supported near field communication device
First Claim
1. A spindle supported near field communication (NFC) device, comprising:
- a spindle configured to mount to a mounting surface; and
a beam shaping NFC device including;
a ferromagnetic component including;
a core portion, wherein the core portion defines a core cavity and the spindle is inserted within the core cavity;
a first flange portion; and
a second flange portion; and
a wire coil disposed around the core portion between the first flange portion and the second flange portion, wherein the ferromagnetic component concentrates near field interrogation signals generated by the wire coil toward a near field interrogation region and away from the mounting surface;
a ribbon supply spool configured to mechanically attach with a ribbon supply roll, the ribbon supply spool to rotate around the spindle; and
a bearing component configured to facilitate rotation of the ribbon supply spool around a spindle rod portion of the spindle, the bearing component including;
a bushing disposed between an exterior surface of the core cavity of the ferromagnetic component and the spindle;
a first washer disposed around the bushing;
a second washer disposed around the spindle; and
a bearing disposed around the spindle between the bushing and the second washer.

Abstract
Systems, devices, and related methods for shaping near field interrogation signals are discussed herein. Some embodiments may provide for a spindle supported near field communication (NFC) device including a spindle configured to mount to a mounting surface, and a beam shaping NFC device. The beam shaping NFC device may include: a ferromagnetic component including a core portion, wherein the core portion defines a core cavity and the spindle is inserted within the core cavity; and a wire coil disposed around the core portion. The ferromagnetic component may be configured to concentrate near field interrogation signals generated by the wire coil toward a near field interrogation region and away from the mounting surface, or other components capable of causing interference or degradation of the near field interrogation signals.
