circuitry

Telemetering transmitter removed from its pressurized container. The circuitry for each of the 23 channels can be quickly unplugged for servicing.

In the microelectronics area, research and development efforts will concentrate on thin film circuitry, packaging and solid state electronics (work with transistors and the like). … The savings in weight over old-fashioned circuitry are important when the cost of items in orbit is figured at $1,000 per pound.

Since [Santiago Ramón y] Cajal's neural circuitry did not include inhibitory cells, he believed that short-axoned cells were important in maintaining a continuous and persistent activity in neural centers.
