SURGERY; IDENTIFICATION (usefulness limited to only animals A61D) ## Abstract A light cable for conveying light from a light source to an endoscope includes a first connector at a proximal end of the light cable for connecting to the light source; a second connector at a distal end of the light cable for connecting to the endoscope; a light guide for conveying light received from the light source to the endoscope; a first wireless antenna positioned at the proximal end for wireless communication with the light source; and a second wireless antenna positioned at the distal end for wireless communication with the endoscope. ## Claims ### Claim 1 A system for providing light for endoscopic imaging, the system comprising: an endoscope comprising an RFID tag; a light cable comprising an RFID reader configured to communicate with the RFID tag of the endoscope, and an RFID tag communicably coupled to the RFID reader of the light cable; and a light source, comprising: at least one light generator for generating light for providing to the endoscope via the light cable; a port for connecting the light cable; and an RFID reader configured to wirelessly receive signals from the RFID tag of the endoscope via the RFID tag of the light cable when the light cable is connected to the port. ### Claim 2 (depends on 1) The system of claim 1, wherein the light cable comprises: a first connector at a proximal end of the light cable for connecting to the light source; a second connector at a distal end of the light cable for connecting to the endoscope; a light guide for conveying light received from the light source to the endoscope; a first wireless antenna positioned at the proximal end for wireless communication with the light source; and a second wireless antenna positioned at the distal end for wireless communication with the endoscope. ### Claim 3 (depends on 1) The system of claim 1, wherein a wired connection connects the first wireless antenna and the second wireless antenna for conveying signals between the first and second wireless antennas. ### Claim 4 (depends on 1) The system of claim 1, wherein the RFID tag of the light cable stores information associated with the light cable. ### Claim 5 (depends on 1) The system of claim 1, wherein the RFID tag of the light cable is an active RFID tag that is wirelessly powered by the RFID reader of the light source. ### Claim 6 (depends on 5) The system of claim 5, wherein the active RFID tag provides power to the RFID reader of the light cable. ### Claim 7 (depends on 1) The system of claim 1, wherein the RFID reader of the light source comprises an antenna positioned in the port and configured for receiving the signals from at least one antenna positioned in a connector of the light cable. ### Claim 8 (depends on 1) The system of claim 1, wherein the light source further comprises one or more processors, a memory, and one or more programs stored in the memory for execution by the one or more processors for updating data stored in a memory of the light cable, a component connected to the light cable, or both the light cable and the component connected to the light cable via wireless transmission of data to the light cable. ### Claim 9 (depends on 1) The system of claim 1, wherein the signals comprise data associated with at least one characteristic of the light cable, the endoscope, or both the light cable and endoscope, and the system further comprises one or more processors, memory, and one or more programs stored in the memory for execution by the one or more processors for controlling the at least one light generator based on the at least one characteristic. ### Claim 10 (depends on 9) The system of claim 9, wherein controlling the at least one light generator based on the at least one characteristic comprises controlling a power level of the light provided to the light cable. ### Claim 11 (depends on 9) The system of claim 9, wherein the signals comprise data associated with the at least one characteristic of the light cable, the endoscope, or both the light cable and endoscope, and the system further comprises one or more processors, memory, and one or more programs stored in the memory for execution by the one or more processors for providing a notification to a user associated with a suitability of the light cable, the endoscope, or both the light cable and endoscope for a requested lighting mode. ### Claim 12 (depends on 1) The system of claim 1, wherein the signals comprise data associated with at least one characteristic of the light cable, the endoscope, or both the light cable and endoscope, and the at least one characteristic comprises usage tracking data, service tracking data, type data, or calibration data. ### Claim 13 A method comprising: connecting a light cable to a light source that is configured to generate light for providing to an endoscope via the light cable; and wirelessly transmitting data from the light cable to an RFID reader of the light source, wherein the data is transmitted by the endoscope via one or more signals that are conveyed along the light cable to a proximal end of the light cable for wireless transmission to the RFID reader of the light source. ### Claim 14 (depends on 13) The method of claim 13, further comprising controlling an aspect of the light generated by the light source based on the data transmitted from the light cable to the RFID reader. ### Claim 15 (depends on 13) The method of claim 13, further comprising wirelessly transmitting data from the RFID reader to the light cable for storing in a memory of the light cable, a memory of the endoscope, or both. ### Claim 16 (depends on 13) The method of claim 13, further comprising providing a notification to a user of a suitability of at least one of the light cable and the endoscope for a requested lighting mode. ### Claim 17 (depends on 13) The method of claim 13, further comprising generating images based on the data transmitted from the light cable to the RFID reader of the light source, wherein the data comprises at least one characteristic of at least one of the light cable and the endoscope, and wherein generating images comprises performing image processing based on the at least one characteristic.
