Abstract: A wearer adjustable apparatus is configured for a wearer to view an object and adjust stimuli projected into the eye by adjusting the location of the projection optics, for example with movement of the projection optics relative to one or more components of a support such as an eyeglass frame. In some embodiments, the projection system comprises an adjustable retainer for the wearer to adjust first active projection elements coupled to a first support in front of a first eye in relation to second projection optics coupled to a second support in front of a second eye of the wearer. In some embodiments, the apparatus comprises oculars comprising the projection optics and corrective lenses configured for the wearer to adjust positions of the lenses and projection optics in front of the wearer's eyes in order to project therapeutic spots onto a desired location relative to the wearer's retinas.

Abstract: A method of mechanically connecting a connector to a first object includes providing the first object having an opening, providing a first connector element, a second connector element, and thermoplastic material in a solid state, placing the first and second connector elements relative to the opening, causing energy to impinge on the thermoplastic material until at least a portion thereof becomes flowable and flows relative to the first and second connector elements until it is in direct (intimate) contact with both the first and second connector elements, and causing the thermoplastic material to re-solidify (for example by letting the thermoplastic material to cool down to room temperature). The re-solidified thermoplastic material locks the first and second connector elements relative to one another to yield a connector assembly that is anchored in the opening by the thermoplastic material and/or by the locking of the first and second connector elements.

Abstract: A method of bonding a connector to a first object includes providing the connector, the connector being separate from the first object and including a thermoplastic material; arranging the first object and the connector relative to one another so that the connector reaches from a proximal side of the object through a first opening in the object; generating and applying vibrations and mechanical pressure to the connector until a flow portion of the thermoplastic material is liquefied and caused to flow sideways radially into an open space; and removing the source of the vibrations and causing the liquefied thermoplastic material to re-solidify, resulting in the connector with a foot portion, a head portion, and a shaft portion between the foot portion and the head portion. The shaft portion extends along an axis through the first opening, and secures the connector to the first object.
