The Device
The current UK G4S administered ankle device is made up of a black band, approximately 2.5 cm in width, with an 8 cm long x 3 cm wide grey 'heart'. Along the length of the black strap at the edges run 2 length of fibres which only appear to add strength to the black strap. Additionally, and presumably to record any deliberate cutting of the strap, runs what appears to be a 10-or-so core fibre optic cable which pulses roughly every 1/2 second. Each ankle device has a serial number and a telephone number imprinted on it, should one need to contact the control room.

“It is my hope to be able to prove that television is the greatest step forward we have yet made in the preservation of humanity. It will make of this Earth the paradise we have all envisioned, but have never seen.”
—Joseph O’Donnell. Clifford Sanforth. Professor James Houghland, Murder by Television, just before he demonstrates his new television device (1935)
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
