Abstract: The present invention relates to methods for supplementing the diet of subjects suffering from cardiovascular disease. D-Ribose is given long term alone or in combination with vasodilators in order to improve or maintain the diastolic or systolic function of the subjects.

Abstract: An LED driver may use a DIAC oscillator circuit to controls a semiconductor switch in a switching circuit. The DIAC oscillator circuit uses rectified line power and so it does not require a separate power source. An LED driver may uses a zero crossing circuit to provide low level dimming. The zero crossing circuit includes a linear circuit or a constant current circuit that keeps a TRIAC dimmer on and stable during low current levels.

Abstract: A ribose-related compound is added to whole blood or packed red cells which have suboptimal function as measured by decreased levels of 2,3-DPG in order to rejuvenate the red blood cells to normal function as seen by raised levels of 2,3-DPG. Two representative ribose-related compounds are D-ribose and inosine.

Abstract: Board level conditions associated with the operation of multiple LEDs are sensed and used to control a driver that powers the LEDs. The driver is controlled via a 0-10V control interface. The board-level conditions include, but are not limited to, temperature, ambient light, light intensity, operating time, time of day, current, and voltage. An on-board intelligent (OBI) controller processes the 0-10V control signal before it is provided to the driver to better control the LEDs. In some systems the OBI controller works in conjunction with a separate 0-10V controller that controls one or more luminaires.

Abstract: Anti-theft devices are provided for use with both new and previously installed utility boxes. The utility box includes a sidewall, typically set into the ground, and the anti-theft device includes a bracket that hooks beneath the sidewall. The bracket also includes a threaded bore disposed through a fastening piece. The utility box also includes a cover that seals a top opening of the sidewall. The cover includes a hole for receiving a bolt. The threaded bore aligns with the hole in the cover so a bolt can engage the threaded bore to secure the cover to the bracket.
