A method and apparatus for measuring intraocular pressure of an eye use an empirically derived function wherein an inward applanation pressure P1 and an outward applanation pressure P2 obtained during a corneal deformation cycle caused by a fluid pulse are separately weighted so as to minimize cornea-related influence on the intraocular pressure value calculated by the function. The charging unit forms part of the reverse passage and includes a charger between an inner side of the reverse passage and one of rotation members. The first sensor head of said orthogonal flux-gate magnetometer is placed in a region in which magnetic flux density is increased through a magnet collection effect by the second magnetic core of said search-coil magnetometer. Accordingly, the present invention includes an error check and correction module that detects invalid data words after parallel-to-serial conversion. The nozzle is coupled to the rinse aperture and is adapted to rotate and direct flow of the rinse fluid outwardly while rotating. The ready-baked dough pieces are made available in at least one supply bin that is accessible to the customer.
