Abstract: Separate electrical timing and load activation devices are provided for each of plural electrical loads and each device is connected to receive reference timing signals from a central unit. Each of the separate timing and load activation devices measures a reference time interval accurately defined by the reference timing signals and subsequently activates its associated electrical load after a respectively corresponding predetermined time delay which is determined as a function of the locally measured reference time interval.

Abstract: An ignition system for the firing of a plurality of electrically actuable igniters (16) and methods for construction and use of the assembly. The ignition leading wire (17) of each electrically actuable igniter (16) is formed from a continuous length of insulated wire connecting its two electrical connection terminals. The leading wire is looped around a transformer core (14) having a movable portion (15) that is opened to admit the loop. A firing cable (12) coupled to a source of electrical firing energy (11) is also looped around the transformer core completing the formation of a transformer for coupling electrical firing energy from the source to each of the igniters to be fired. A plurality of transformer cores can be coupled to a single firing energy source by looping a continuous wire from the source, through each transformer and then back to the source, thereby electromagnetically coupling firing energy to each transformer.
