Abstract: An apparatus for obstructing the passage of debris and providing ventilation through a region between a first object and a second object, the apparatus comprising: a body; and a plurality of tines extending from the body, wherein the tines are arranged in use such that when the body is connected to the first object, the tines extend across the region and flex against the second object leaving channels between the tines in the region allowing for ventilation.

Abstract: A stator assembly including at least one pair of c-shaped stator cores, each c-shaped stator core having a bobbin, and a winding wound around each bobbin, wherein the windings on each adjacent pair of c-shaped stator cores are wound in opposite directions.

Abstract: A manual device for massaging one or both of the upper and lower lids of the eye, the device including: a body, composed of flexible resilient biocompatible material, wherein the body provides jaws or lips, wherein the lips are biased into a spaced relationship by the material of the body, and wherein each lip is adapted to engage either the upper or lower eyelid, such that movement of the lips causes movement of at least one eyelid with respect to the other. The devices can conveniently be used to manipulate the meibomian glands of the eye in an optimum orientation, for example for alleviating or treating dry eye.
