Abstract: A neural interface arrangement has multiple probes for subdural implantation into or onto a human brain. Each probe has at least one sensing electrode, a coil for receiving power via inductive coupling, signal processing circuitry coupled to the electrode(s), and a transmitter for wirelessly transmitting data signals arising from the electrode(s). An array of coils is implanted above the dura beneath the skull, for inductively coupling with the coil of each probe, and for transmitting power to the probes. A primary coil is connected to the coil array, for inductively coupling with an external transmitter device, and for receiving power from the external transmitter device. In use, the primary coil is operable to receive power from the external transmitter device by inductive coupling and to cause the coil array to transmit power to the probes by inductive coupling, and the probes wirelessly transmit data signals arising from the electrodes.

Abstract: A method by which a hub unit can discover IDs from a plurality of satellite units across a shared communication link that connects each of the satellite units to the hub unit, each satellite unit having a satellite unit ID, the method comprising the hub unit broadcasting a message over the shared communication link, the message including an ID segment with a string of bits shorter than a bit length of the satellite unit IDs and an ID segment location; and each satellite unit receiving the broadcast message and comparing the ID segment with an ID portion of its own satellite unit ID starting at the ID segment location, if the ID portion for a satellite unit matches the ID segment, the satellite unit transmitting its complete satellite unit ID to the hub unit over the shared communication link.

Abstract: A method of optically outputting information (e.g. digital data) from a semiconductor device, the method comprising: providing a semiconductor device having a semiconducting p-n junction, the p-n junction having a region of reduced free charge carrier density; applying an electrical signal to modulate the extent of the said region, the electrical signal being representative of the information to be outputted; arranging incident light to pass through at least part of the said region, such that the light is at least partially absorbed in dependence upon the modulated extent of the said region, thereby producing intensity-modulated output light; and detecting the intensity of the output light and thereby determining the outputted information. Also provided is an electro-optical assembly, a package module for mounting a semiconductor device on a printed circuit board, and an integrated circuit chip.
