Abstract: A device for transdermal electrochemical measurements, comprising a polymeric support having a surface provided for contact with skin, an array of polymeric microneedles integral with the support and projecting outward from the surface of the support, and a porous and/or nano/micro-structured bioelectrode. A biologically active species is immobilized on the surface of a conductive material. The microneedles and a surface of contact of the support with the skin are formed of a biocompatible crosslinked hydrogel, non-electron-conductive in the dry state and electrolyte-conductive upon contact with an aqueous fluid. The bioelectrode is arranged in contact with the hydrogel and is free of direct contact with the skin. Methods for preparing and using the device are also described.

Abstract: An apparatus (110), system (100), and method (900) for displaying an image (880). Instead of using an expensive configuration of prisms (310) such as TIR prisms (311) or RTIR prisms (312) to direct light (800) to and from a DMD (324), a plate (340) with transmissive (374), reflective (372), and/or polarization (373) characteristics is used. The plate (340) can be implemented in a wide variety of different embodiments using a wide variety of different components and configurations.

Abstract: A BMX starting gate includes a frame with a gate opening; a slider bar attached to a bottom surface of the frame; a gate pivotally attached to the frame at a connection point such that the gate aligns with the gate opening; a linkage bar attached to the gate proximate to the connection point; a lever attached to the linkage bar distal from the gate, wherein both the linkage bar and the lever are slidably attached to the slider bar; a strike plate attached to the lever distal from the linkage bar; an electromagnet attached to the frame, wherein the electromagnet is positioned to releasably engage with the strike plate; and a spring connecting the gate to the slider bar. Activating the electromagnet causes the electromagnet to engage the strike plate and cause the gate to extend outwardly from the frame. Deactivating the electromagnet allows the spring to return the gate to a non-obstructing position.
