There are various consumer brain–computer interfaces available for sale. These are devices that generally use an electroencephalography (EEG) headset to pick up EEG signals, a processor that cleans up and amplifies the signals, and converts them into desired signals, and some kind of output device.
The BCI operated in real time and could remotely control a separate robot. But the monkeys received no feedback (open-loop BCI). Diagram of the BCI developed by Miguel Nicolelis and colleagues for use on rhesus monkeys. Later experiments on rhesus monkeys included feedback and reproduced monkey reaching and grasping movements in a robot arm.

Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium , chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.
Napier gave details of a scheme for arranging the tables so that no rod has two copies of the same table, enabling every possible four-digit number to be represented by 4 of the 10 rods. A set of 20 rods, consisting of two identical copies of Napier's 10 rods, allows calculation with numbers of up to eight digits, and a set of 30 rods can be ...
Reinforcing bars in masonry construction have been used since antiquity, with Rome using iron or wooden rods in arch construction. [5] Iron tie rods and anchor plates were later employed across Medieval Europe, as a device to reinforce arches, vaults, and cupolas. [6] [7] 2,500 meters of rebar was used in the 14th-century Château de Vincennes. [8]
