Patent GB-2054118-A (GB)
Title: Test gas vessel
IPC: B01L3/12
Filed: 1980-05-28
Abstract: A test gas vessel (1) is provided with an inert, pervious material (2).

Title: Apparatus for the electrical stimulation of nerves
Inventor: FOURCIN ADRIAN JOHN
IPC: A61F11/04
Filed: 1984-01-19
Abstract: Apparatus primarily for stimulating the auditory nerve in the vicinity of the cochlea of deaf persons to give a sensation indicative of the pitch of speech is described. The stimulus which is in the form of an alternating current of varying period dependent on the pitch of speech is applied to an electrode 36. The current is non-zero for most of the duration of most stimulation periods and in order to elicit a stable auditory sensation d.c. baseline fluctuation is prevented by the use of a controlled current generator 44. The period of speech sounds is found using a specially devised circuit and a voltage related to the frequency of such sounds is determined by the period-to-voltage converter 43 and a reciprocal circuit 38, this voltage being supplied as a control signal for the generator 44. An alternative microcomputer version is also described. In order to give an indication of the presence of voiceless sounds, a detector capable of distinguishing between voiced and voiceless sounds is also included together with a noise source which is coupled to the stimulation electrode when the detector indicates the presence of voiceless sounds. <IMAGE>
