Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

Abstract: Very high refractive index (n>2.2) lightguide substrates enable the production of 70° field of view eyepieces with all three color primaries in a single eyepiece layer. Disclosed herein are viewing optics assembly architectures that make use of such eyepieces to reduce size and cost, simplifying manufacturing and assembly, and better-accommodating novel microdisplay designs.

Abstract: A needle hub (10) for a pen needle is provided with an enlarged surface for contact with the skin of a patient. The enlarged surface is provided with a surface having a dimension and shape to enable a needle or cannula to penetrate the skin to a desired depth and permit substantially the entire exposed length of the needle or cannula to penetrate the skin to the desired depth. The surface of the needle hub can be formed by an inner cone shaped member (26) forming a first contact surface with a surface area of about 1-5 mm2 and an outer ring (28) at a peripheral edge forming a second contact surface with a combined surface area of about 15 to 50 mm2.

Abstract: A needle-bearing hub for a pen needle is provided with a distal patient-facing side having an enlarged surface for contact with the subject's skin. The enlarged surface is provided with a radius of curvature that increases the likelihood that the needle reaches full injection depth when an injection is performed at an inclined angle with respect to the surface of the skin and with to the desired depth less discomfort to the patient.

Abstract: A needle hub assembly for a pen needle includes a needle hub, an inner shield and an outer cover. The open end of the outer cover is closed by a removable seal to access the needle hub. The needle hub has a body with a shoulder and a tower extending from the body for supporting a cannula. The inner shield fits over the tower and the cannula and includes a flange that has an outer dimension complementing the outer dimension of the needle hub and contacts the shoulder of the needle hub in the assembled condition. The outer cover encloses the needle hub and the inner shield and includes a stop member on an inner surface that contacts the flange of the inner shield to capture the inner shield between the shoulder of the needle hub and the outer cover.

Abstract: A delivery device system is provided for assisting a patient and physician in maintaining a depth and position of an inserted catheter within a target tissue. The delivery device includes a base member that is secured to an external surface of the patient. The base member includes an aperture through which a catheter is inserted to access the target tissue. The base member further includes a hinged clip that selectively locks into a closed position to secure the catheter within the delivery device and maintain a desired insertion depth of the catheter within the target tissue. The base member further includes a receiving channel for compatibly and adjustably securing an adapter portion of the catheter in a horizontal orientation.

Abstract: The present disclosure includes, among other things, systems, methods and program products for pre-computing image manipulations.

Abstract: A system and method is provided for an injectable substance delivery device comprising a limiter, shoulder or post, that controls how deep the needle is inserted into the tissue. The limiter is sized in proportions that control the maximum insertion depth of the needle into the tissue without excessively restricting the complete insertion of the needle. The system and method further comprises an normalization or stabilizer ring that prevents distortion of the tissue in the vicinity of the infusion, so that the needle length is the major determining factor as to how deep the infusion is delivered.
