Abstract: A linear light emitting diode (“LED”) light fixture includes LED modules that interface with one another to provide a substantially continuous array of LED's. This continuous array allows for substantially uniform light output from the LED light fixture. The LED modules can interface with one another via one or more connectors, which allow two or more LED modules to be electrically and mechanically coupled together. The connectors may be disposed beneath the LED's so that the connectors are not visible when the LED modules are coupled together. The connectors may be disposed along opposite ends of the modules to allow for end-to-end configurations of the modules and/or along side ends of the modules to allow for angled or curved configurations of the modules. The LED modules can be powered via one or more wires, magnets, or clips, which are coupled to a power source.

Abstract: A linkable linear light emitting diode (LED) system provides apparatus and method for mechanically, optically, and electrically linking multiple LED modules disposed over a wide and separated area of a ceiling system. Openings can be cut in ceiling tiles of a drop ceiling system and the LED lighting modules are coupled to the tile through the opening, with the tile being sandwiched between different portions of the module. A remote driver system is placed within the drop ceiling above the tiles and provide multiple connectors for powering a multitude of lighting modules. Certain of the LED lighting modules include both input and output connectors for both receiving power or data and providing power or data to other modules. In this manner, some of the modules act as master LED lighting modules and those receiving power and/or data therefrom are act as slave modules.

Abstract: A light emitting diode (LED) module having a configurable LED substrate capable of receiving varying numbers and layouts of LEDs are described herein. The LED substrate includes LED coupling points for receiving the LEDs and electrical traces etched into the substrate for routing power to the LEDs. The LED module can include a multi-LED over-optic having multiple over-optics that are configured to match the number and configuration of the LEDs positioned on the substrate. The LED coupling points and over-optics can be arranged symmetrically to enable the LED module to be rotated to adjust the light output distribution and direction. The LED module can include a power connection mechanism, for example located at the center of the substrate, that also allows the LED module to be rotated. One or more of the LED modules may be mounted on a heat sink and incorporated into a light fixture.

Abstract: A method and apparatus for determining vulnerable plaque in a cardiovascular lumen is disclosed. In one embodiment, a guide member comprising a temperature sensor and a distance sensor are inserted into the cardiovascular lumen. The temperature of the cardiovascular wall is measured with the temperature sensor, and the distance from the temperature sensor to the cardiovascular wall is determined. The cardiovascular wall temperature is adjusted based on the distance determination, and the vulnerable plaque is determined based on the adjusted wall temperature measurement.

Abstract: In general, the invention is directed to methods and devices for determining an ion concentration in the extracellular fluid of a patient. As examples, the ion may be one or more of potassium, sodium, chloride, or calcium. A system includes an electrode deployed in or near a tissue, such as a skeletal muscle, of the patient. A pulse generator supplies one or more stimulations to the tissue, and a sensor, such as an accelerometer, detects the response of the tissue to the stimulations. A processor determines a concentration of ions in the extracellular fluid as a function of the response. The system may detect an ion imbalance based upon the determined concentration of ions.

Abstract: A method for detecting vulnerable plaque lesions in a blood vessel includes subjecting a localized area of the blood vessel to pressure pulses, while emitting electromagnetic radiation at the same localized area of the blood vessel. The pressure pulses cause vibrations of the vascular tissue and the vulnerable plaque lesions that are characteristic for each, which results in differing amounts of deflection of the electromagnetic radiation reflected from the vascular surface. The presence or absence of vulnerable plaque is determined from the extent of the deflection of the electromagnetic radiation reflected from the vascular surface. In another embodiment according to the invention, the presence or absence of vulnerable plaque lesions is determined from the intensity of vibrations of the vascular tissue in response to a pressure pulse.
