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.

Famous quotes containing the word device:
“A bracelet of bright hair about the bone,
Will he not let us alone,
And think that there a loving couple lies
Who thought that this device might be some way
To make their souls, at the last busy day,
Meet at this grave, and make a little stay?”
—John Donne (1572–1631)
“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)
