Abstract: The running of a program, designed to train the user to control one or more aspects of his or her psycho-physiological state, is controlled by signals representative of a psycho-physiological parameter of the user, e.g., galvanic skin resistance. This may be detected by a sensor unit with two contacts on adjacent fingers of a user. The sensor unit is separate from a receiver unit which is connected to a computer running the program.

Abstract: Apparatus and a program designed to train the user to control one or more aspects of his or her psycho-physiological state is controlled by signals representative of a psycho-physiological parameter of the user, e.g. galvanic skin resistance. This may be detected by a sensor unit with two contacts on adjacent fingers of a user. The sensor unit can be separate from a receiver unit which is connected to a computer running the program. The apparatus is described for use in treating patients with a physiological condition, for example, irritable bowel syndrome. In a treatment session, one or more psycho-physiological parameters of the patient is sensed and the sensed parameter used to alter a display which the patient watches. The display includes a visual or pictorial representation of the physiological condition being treated which changes in appearance in a fashion corresponding to the physiological change desired in the patient.

Abstract: A speech aid device has a housing with a tubular main body enclosing a battery and an electric motor. An obliquely directed side arm of the housing has a diaphragm resiliently mounted at the free end. A striker is guided for reciprocable movement along the side arm axis to beat against the other face of the diaphragm and is driven by the motor through a gear box and an eccentric drive. A tension spring is included in the drive and a compression spring opposes the striker return movement, so that the striker is floatingly mounted by the springs. A feature of the drive is a resilient link between the motor and hammer.
