Abstract:
A light polymerizable composition for use in the additive manufacturing of medical devices may include a first photo-initiator and a second photo-initiator. The first photo-initiator activates to initiate curing of the composition when exposed to light of a first wavelength in an additive manufacturing device and the second photo-initiator limits the transmission of the light of the first wavelength that activates the first photo-initiator in the additive manufacturing device. The second photo-initiator is activated to further cure the composition when exposed to a light of a second wavelength different from the first wavelength by activating the second photo-initiator to produce free radicals at a higher rate when exposed to the light of the second wavelength than when exposed to the light of the first wavelength.
Abstract:
A process for additive manufacturing of a resorbable implant to be implanted into a patient includes providing a biocompatible resin including a liquid light-polymerizable material that is resorbable after polymerization and an initiator. The process further includes actuating an additive manufacturing apparatus to expose an amount of the biocompatible resin to light to at least partially cure the exposed amount of biocompatible resin to form a layer of the resorbable implant and actuating the additive manufacturing apparatus to expose at least some additional amount of biocompatible resin to light to at least partially cure the exposed additional amount of biocompatible resin to form an additional layer of the resorbable implant and to at least partially overcure previously cured layers to cause at least some interlayer binding between the previously cured layers and the additional layer.
Abstract:
An aqueous humor outflow device includes an arcuate scaffold that fits within a conventional aqueous humor outflow pathway of a mammalian eye to receive aqueous humor from a trabecular meshwork of the mammalian eye and allow flow of the aqueous humor through the arcuate scaffold to one or more collector channels that originate in a posterior wall of a Schlemm’s canal. The arcuate scaffold includes a first arcuate rail, and a second arcuate rail spaced apart from, and substantially parallel to, the first arcuate rail. The first and second arcuate rails each have an anterior edge that is adjacent to the trabecular meshwork when inserted in the Schlemm’s canal, and a posterior edge that is adjacent to the posterior wall of the Schlemm’s canal. Structural components coupled to the first arcuate rail and the second arcuate rail maintain the respective anterior and posterior edges of the first and second arcuate rails spaced apart from, and substantially parallel to, each other.
Abstract:
In one embodiment, a graphic image display can comprise: a backlight source; a light transmitting first sheet having a viewing side and a backside, with a plurality of geometric microstructure units on the backside; and a second layer comprising a source of graphic image information. The plurality of geometric microstructure units can be selected from microlenses, polyhedral shapes, lenticular shapes, and combinations comprising at least one of the foregoing. The graphic image display can be suitable for viewing under ambient light from the viewing side alone, under backlighting alone, and in the presence of both ambient light from the viewing side and backlighting.
Abstract:
A computer implemented method for determining the 3-dimensional shape of an implant to be implanted into a subject includes obtaining a computer readable image including a defective portion and a non-defective portion of tissue in the subject, superimposing on the image a shape to span the defective portion, and determining the 3-dimensional shape of the implant based on the shape that spans the defective portion.
Abstract:
A trailer backup steering input apparatus is coupled to a vehicle. The trailer backup steering input apparatus comprises a rotatable control element (e.g., a knob) and a rotatable control element movement sensing device. The rotatable control element biased to an at-rest position between opposing rotational ranges of motion. The rotatable control element movement sensing device is coupled to the rotatable control element for sensing movement of the rotatable control element. The rotatable control element movement sensing device outputs a signal generated as a function of an amount of rotation of the rotatable control element with respect to the at-rest position, a rate movement of the rotatable control element, and/or a direction of movement of the rotatable control element with respect to the at-rest position.

Abstract:
A removable flexible jacket for use in a printing press having a transfer cylinder for transferring a freshly printed substrate. The removable flexible jacket comprises a film sheet, a plurality of beads coupled to the film sheet by a bonding material, wherein the beads are of different sizes, and a coating partially covering the beads, wherein a cusp of at least some of the larger beads is substantially free of the coating.
Abstract:
A method of filtering/rejecting targets detected by a forward collision warning system of a motor vehicle when entering a curved road segment. The width of a collision threat zone (CTZ) is reduced in one or more stages depending upon continuously-measured values of steering input angle (SIA), driver brake application (DBA), and a yaw rate. The measured values are used to find: a degree of near-past DBA variation during a first look-back period, a degree of near-past SIA change rate during a second look-back period, and a degree of far-past yaw rate change during a third look-back period longer than the first and the second look-back periods. A series of first, second and third width reductions of decreasing severity are applied to the CTZ based upon comparisons of the tracked variations and change rates with respective thresholds. The thresholds are tunable to achieve desired levels or false-target rejection.
