Abstract: An article of manufacture, comprising: at least one point source of light which emits a light beam; and at least one reflective means for diffusing the light and/or converting the light to a different color range. The goal of this invention is to greatly increase the energy efficiency of area lighting by the use of highly efficient beams light sources.

Abstract: The present invention discloses an integrated electronic light source module that has a base plate to support an electronic light source; a power supply to drive this light source; and a heat sink to dissipate the heat generated by this invention. The cooling fins of the heat sink are in perpendicular relation to the axis along which the natural flow of heat is oriented. Such a setup provides for effective heat dissipation and a more rapid cooling then disclosed in the prior art. Although, the present invention can be completely autonomous, an optional coupling unit can be included that is adapted to connect to an external power source, such as a socket of a light fixture. The electronic light source embodies the use of an LED element, or of a more traditional fluorescent lighting. The present invention increases modularity of the device by integrating all components needed for an effective prolonged illumination into a single swapable module.

Abstract: An article of manufacture, comprising: an LED or other light source in thermal communication with a thermoelectric module; and a feedback circuit that directs current generated by the thermoelectric module to at least one device. This invention improves on prior art by recycling heat produced by the LED or other light source into electricity produced via the thermoelectric module to be used by the light source, a cooling device, battery charger for battery backup system, control or monitoring system, etc.

Abstract: An implantable cardiac stimulation device, such as a pacemaker, defibrillator and/or cardioverter, and an associated method that provide cardiac stimulation to at least two ventricular stimulation sites, within a single ventricle or across two ventricles. A high intrinsic atrial rate triggers a retrograde conduction detection routine when a high ventricular stimulation rate is sustained for a predetermined number of cycles during an atrial sensing mode. This routine interrupts concurrent stimulation, and alternates the stimulation output to the different ventricular sites.

Abstract: A signal source coupled to one or more electrodes in the vicinity of the diaphragm for mapping therapeutic electrode sites. A stimulus signal from the signal source may be applied to the one or more electrodes to produce activation of the diaphragm. Activation of the diaphragm is sensed to provide information that may be correlated with the stimulus signal. The correlated information may be used to identify a therapeutic locus for a therapeutic electrode. An electrical stimulus comprising a series of pulses may be applied to the one or more electrodes to elicit a desired breathing response. The electrical stimulus may be applied between intrinsic breathing cycles, or between regulated breathing cycles. More than one electrode may be supported on a single substrate. The substrate may configured to be positioned on the diaphragm. A hierarchy of stimuli may be applied to a set of electrodes.

Abstract: An implantable cardiac stimulation device including a ventricular defibrillator and a rate adaptive cardiac pacer automatically adjusts post-pacing sensing parameters dependent upon pacing rate. The device includes a pulse generator that applies stimulation pulses to a heart at a calculated variable stimulation rate as a function of physiologic demand. A sensing circuit senses ventricular activity of the heart responsive to a plurality of sensing parameters including post-pace sensing parameters and a processor adjusts the post-pace sensing parameters responsive to the selected pacing rate.
