KBK update for Sunday, 28th March

There are certain keyboard designs that, for the moment, seem specific to a single company. One of these is IKOR’s capacitive encoding system, which may be their only keyboard design. No such keyboard is yet know to have been observed, and it seems that they did not remain the market for many years. IKOR keyboards used a self-encoding technique where each output bit is detected separately via capacitance. An electrostatic shield is fitted to each key, with a hole punched in it for each output bit to be set as a 1. Details are given in the patents, and some rough illustrations are also posted to help explain this rather strange sensing and encoding method.
