Abstract: An integrated nanowire device includes a first array of nanowires having a first set of characteristics and a second array of nanowires having a second set of characteristics. A processor is electrical communication with the first and second arrays of nanowires receives the first plurality of charges and generate a processor signal therefrom. The second array of nanowires may be configured to produce a stimulation current in response to the processor signal. The first or second array may be used to generate power for operation of the device, or the arrays may function as a stimulator, sensor combination to enable the device to self-regulate based on localized responses to stimulation. The device may be implanted for use as a neural stimulator.

Abstract: Methods are provided for treating pathological conditions of ocular tissue by administering to subjects in need thereof therapeutically active complexes that include amphiphilic analogs of the therapeutically active agents. These complexes exhibit low water solubility and are isolated in either crystalline form, amorphous form, or a combination thereof, within a well-defined particle size range. Administration of such complexes of therapeutically active agents to ocular tissue results in extended release of the therapeutically active agent. Indeed, certain complexes persist for up to about 20-30 weeks or longer after intravitreal injection, thereby providing a sustained release of therapeutically active agent into the structures of the eye.

Abstract: A compact optical isolator includes a polarizer, a Faraday rotator, and an analyzer that are arranged in series. A magnet is also included to provide a magnetic field to the Faraday rotator. The outer edges of the polarizer, Faraday rotator, and analyzer are preferably parallel to each other and to the optical path of the incoming light beam so that the optical aperture through the optical isolator is maximized. In addition, each of the polarizer, the Faraday rotator, and the analyzer have at least one facet in the optical path of the light beam that is tilted from perpendicular with respect to the light beam such that reflections are avoided. The analyzer may have a wedge shape such that one surface mates level with an optical fiber and the opposing surface is tilted to prevent reflections. Alternatively, a wedge-shaped block may be located between the analyzer and the optical fiber.

Abstract: Exemplary embodiments of the present invention illustrate methods to electrically connect multiple layers of a substrate. A first and second layer each has at least one electrical trace on a surface thereof. The substrate includes an interposer structure attached to the second layer and separating the first and second layers on at least a portion of a perimeter of the first and second layers. The method includes a steps for forming a via in the first layer, placing a first electrically conductive substance in the via, placing a second electrically conductive substance on the second layer adjacent said via, and heating an area around said via and said second electrically conductive substance until said first and second electrically conductive substances at least partially melt to form the electrical connection.

Abstract: A system and method for controlling the temperature of a heat-generating component such as a laser. A microelectromechanical system for controlling the temperature of the heat-generating component includes a magnetic heat sink device, a temperature sensor, and control circuitry. The temperature sensor detects the temperature of the heat-generating component through the heat sink and feeds the sensed temperature to the control circuitry. The detected temperature is compared to a predetermined temperature set point. When the detected temperature is higher than the temperature set point, a command is sent to the magnetic heat sink to take more heat out of the heat-generating component. When the detected temperature is lower than the temperature set point, a command is sent to the magnetic heat sink to take less heat out of the heat-generating component.

Abstract: A micro electromechanical (MEMS) electromagnetic optical switch capable of redirecting light signals to a plurality of different output structures. The optical switch utilizes a movable mirror to redirect light signals. The mirror is magnetically moved into a predetermined fixed position by a magnetic member such that the mirror is positioned to redirect a light signal into one of a plurality of output structures. An electrical assembly induces a temporary magnetic field across the magnetic member to initiate the movement of the mirror.

Abstract: The invention utilizes a virtual reality display to present a random noise stimulus to a patient. Using an input device a patient indicates the location of disturbances in the random noise display. In a preferred embodiment, a scanning retinal laser projects the random noise stimulus directly onto a patient's eye(s). The image is preferably presented at virtual infinity and can be imaged over the peripheral retina. A patient is directed to centrally fixate on the random noise display. A visual aid, such as a cross hair, may be included in the generated display to facilitate this focus. With a scanning laser virtual reality device having a narrow exit, the failure of a patient to centrally fixate causes the image presented to be distorted, incomplete or disappear from view. While a patient views the random noise display, the patient is directed to indicate any areas of disturbance using an input device. A preferred input device is a computer pen and tablet.
