Abstract: A unitary lens comprising a plurality of lens members aligned substantially along a preferential/non-preferential line. Each lens member being elongate across the preferential/non-preferential line with all elongate lens members being in substantially same orientation and each configured for light to exit the unitary lens predominantly toward the preferential side. Each lens member includes an elongate opening for receiving light from a group of emitters aligned across the preferential/non-preferential line; a refracting inner surface forming a void and having a racetrack-shaped surrounding surface extending from the opening to a substantially planar elongate end surface; and a lateral surface having opposed preferential and non-preferential surface portions, the non-preferential portion being at an angle to the base plane which is greater than the angle of the preferential portion to the base plane.

Abstract: A splicing apparatus for continuously unwinding strands of material from wound packages.

Abstract: An apparatus with a rotatable arm for unwinding a strand by taking it off of the side of a wound package

Abstract: A lens for directing light from a light emitter in a preferential-side off-axial direction with respect to the emitter axis. The lens includes an emitter-adjacent base end forming an opening, an inner surface extending from the base end and forming a void, an output-end surface configured to direct light toward the preferential side, and an outer lateral surface configured for TIR to direct light toward the output-end surface, whereby substantially all light from the emitter exits the output-surface predominantly toward the preferential side. Another aspect of this invention is a recessed lighting fixture utilizing the inventive lens.

Abstract: Implant devices for intravesical administration and local drug delivery. The device has a body which includes a hollow tube formed of a biocompatible material; at least one reservoir in the tube which contains a drug; and one or more apertures through which the drug can be released. The device is configured for minimally invasive insertion into a body cavity, such as the bladder. The hollow tube may be elastomeric to permit the device to be elastically deformed from its initial shape into an elongated shape for passage through a catheter, where following such passage the device can return to or toward its initial shape to facilitate retention of the device in the body cavity. The body may have a narrow, elongated shape effective to permit insertion of the drug delivery device through a catheter without necessarily deforming the body, yet include flexible projections which effect retention within the body cavity.

Abstract: The subject application provides an apparatus for applying mechanical loading to a biological sample, said apparatus comprising: a bioreactor device configured to house the biological sample, and a load application unit for applying mechanical loading to the biological sample housed in the bioreactor device, said load application unit including: a) a first sliding arm for applying mechanical displacement to the biological sample in the bioreactor device in a first predetermined direction; and b) a guide rail coupled to the first sliding arm to limit movement of the first sliding arm such that the first sliding arm moves only in the first predetermined direction when displaced.
