Power Conserving Methods for Ultra-Wideband on Brain Computer Interface (BCI) Systems

A cranial implant device, comprising:

• an ultra-wideband (UWB) antenna;
• a near-field communication (NFC) antenna;
• a UWB radio module coupled to the UWB antenna, the UWB radio module configured to transmit short-range, wireless neural data unidirectionally to an external device;
• and
• an NFC module coupled to the NFC antenna, the NFC module configured to receive wireless power signals from the external device.

A method for communicating neural data, comprising:

• at a brain computer interface (BCI) system that includes a cranial implant device and an external device, the cranial implant device including a UWB radio module and a Bluetooth Low Energy (BLE) radio module:
• transmitting, via the UWB radio module, short-range, wireless neural data unidirectionally to the external device;
• receiving, via the BLE radio module, short-range wireless interaction data from the external device;
• and
• transmitting, via the BLE radio module, feedback data to the external device.
