text: The output signal of the multi-vibrator pulse-shaper circuit was the impact-event counting pulse. Its constant parameters provide a better form of input signal for the counting and storing circuitries than the originally tranduced impact signal. The status of the impact event-counting and storage circuitries was telemetered whenever the satellite transmitted its data.

text: Prior art radio and telephone communication headsets typically incorporate a microphone and receiver which require amplifier or other appropriate electronic impedance matching circuits for interface with the console, or at least electrically conductive wires to similar electronic circuitry located in the console.

text: Before he died, James Halliday (Mark Rylance), the hermit-like, socially maladjusted tech genius who created The Oasis, hid an Easter egg somewhere in the circuitry, scattering bread crumbs that lead to its location. Find the egg, and the mogul’s fortune—along with total control of his digital fiefdom—is yours. It’s the ultimate capitalist scavenger hunt!

glosses: A specific system of electrical circuits in a particular device; (uncountable) the design of such a system.
examples: text: 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.

text: The source of that passion [according to René Descartes] is "animal spirits," a circuitry of mechanical energy—blood circulation, heartbeat, muscle tension—whose purpose is not to inform but to protect the body from harm. Although the circuitry operates automatically in animals, in men bodily energies also register on the soul so as to "incite the soul to correct and contribute to the actions which may serve to maintain the body."

glosses: Electrical (or, by extension, other) circuits considered as a group.
examples: text: 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.

text: Some argue that the human brain contains structures or circuitry not found in the brains of other animals. [...] Others emphasize the massive increase in human brain size and posit that human behavior is an emergent phenomenon which reflects quantitative increases in neural processing capacity.

text: Increases in cortical volume translate largely into increases in cortical area, and beneath each area of cortex the cellular composition of the cortical laminae is rather similar. Thus, the operation of making more cortex seems to emphasize local circuitry.

text: The first experiment consists in using the evolutionary algorithm for instantiating low level parameters of a connectionist simulation of the lamprey's locomotor circuitry. The second experiment develops potential neural circuits for the swimming and trotting of the salamander; an animal whose locomotor circuitry has currently not been decoded.

text: Possible changes in pregnancy to explain increased food intake and consequent increased energy storage have been considered in the context of the neural circuitry in the hypothalamus and brain stem that homeostatically regulates appetite, the mesolimbic circuitry regulating hedonic appetite, and the actions of circulating hormones on or in this circuitry.
