The stable pseudo-Heisenburp pattern is a multi-stage converter constructed by Dave Greene in January 2007, using a complex recipe found by Noam Elkies to insert a signal into a 2c/3 wire. The wire's high transmission speed allows a signal from a highway robber to catch up to a salvo of gliders. Ultimately the mechanism restores the key glider, which was destroyed by the highway robber in the first stage of the converter, to its exact original position in the salvo.
Much smaller stable pseudo-Heisenburp devices have since been designed that use simple 0-degree glider seed constellations instead of a 2c/3 wire.[1] More recently, Martin Grant was able to simplify the 2c/3 signal insertion recipe considerably in September 2017[2], allowing for smaller converter circuitry[3] which could also be used to reduce the size of the old pseudo-Heisenburp pattern.
These patterns are labeled "pseudo-Heisenburp", because a true Heisenburp device does not even temporarily damage or affect a passing glider, yet can still produce an output signal in response. However, it is impossible to construct a stable device that can accomplish this for gliders. True stable Heisenburp devices are possible with many other types of spaceships, but not with gliders which have no usable side sparks to initiate an output signal.
When a banana spark hits a loaf, it can turn a block into a glider plus a surplus beehive. This property can be used to make a stable pseudo-Heisenburp for 2-engine Corderships, since they produce banana sparks in an accessible location.[4]
