In accordance with the invention, a low coherence interferometer is used to non-invasively monitor the concentration of glucose in blood by shining a light over a surface area of human or animal tissue, continuously scanning the light over a two dimensional area of the surface, collecting the reflected light from within the tissue and constructively interfering this reflected light with light reflected along a reference path to scan the tissue in depth. Since the reflection spectrum is sensitive to glucose concentration at particular wavelengths, measurement and analysis of the reflected light provides a measure of the level of glucose in the blood. The measurement of glucose is taken from multiple depths within blood-profused tissue, and sensitivity is preferably enhanced by the use of multiple wavelengths. Noise or speckle associated with this technique is minimized by continuously scanning the illuminated tissue in area and depth.

An intervertebral disc space implant includes spaced-apart bone engagement portions that define an intermediate chamber that holds bone growth inducing material into contact with adjacent vertebral bodies. The implant is expandable to establish and maintain desired intervertebral spacing during fusion. The implant includes a first member and a second member arranged to move relative to each other by action of an expansion member, the first member being engageable with the vertebral body below the disc space.

A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines are described. Generally, selected combustion events are skipped during operation of the internal combustion engine so that other working cycles can operate at a better thermodynamic efficiency. In one aspect of the invention, an engine is controlled to operate in a variable displacement mode. In the variable displacement mode, fuel is not delivered to the working chambers (e.g. cylinders) during selected “skipped” working cycles. During active (“non-skipped”) working cycles, a maximum (e.g., unthrottled) amount of air and an optimized amount of fuel is delivered to the relevant working chambers so that the fired working chambers can operate at efficiencies closer to their optimal efficiency. A controller is used to dynamically determine the chamber firings required to provide the engine torque based on the engine's current operational state and conditions. The chamber firings may be sequenced in real time or in near real time in a manner that helps reduce undesirable vibrations of the engine.

External energy source, external charger, system of transcutaneous energy transfer, system of transcutaneous charging and method thereof. An implantable medical device has a secondary coil operatively coupled to therapeutic componentry. An external power source has a housing, a primary coil carried in the housing with the primary coil being capable of inductively energizing the secondary coil when the housing is externally placed in proximity of the secondary coil with a first surface of the housing positioned closest to the secondary coil and a thermo-electric cooling device placed associated with the first surface of the housing.

The present invention is directed to a methods and compositions for receptor mediated drug delivery, particularly across the blood-brain barrier.

A system and method for enhancing the performance of wideband digital RF transport systems is disclosed, which enables the transport of different bandwidth segments on a plurality of wideband channels by selecting an optimal clock sample rate for each bandwidth segment to be transported. Thus, the bandwidth segments are proportionally allocated so that an optimum amount of bandwidth can be transported at the serial bit rate.

Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and / or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

Methods for securitizing and facilitating the securitization of the pawned assets of a pawnshop to enable the pawnshop to obtain a greater amount of funding at reduced rates and to tap into sources of financing in addition to traditional markets. The pawnshop can sell the pawned assets to a first entity to obtain immediate funding, which the first entity can obtain directly or indirectly from other entities in transactions involving a secured financial instrument. Depending on the transactions used, either on-balance sheet or off-balance sheet treatment for the pawnshop of the pawned assets and related liabilities is possible.

An instrument is provided which is in electronic communication with an on board diagnostic system (OBD) of an automobile. The instrument selectively queries the OBD with batch requests for the purpose of reducing a processing load placed on the OBD PCM. The instrument obtains numerous operating conditions through the OBD, and displays the operating conditions in an intuitive format. The operating conditions may be grouped into five different modes, and the five most relevant operating conditions within each mode may be displayed on the monitor either by default or through customization by the user.

A system, method and computer program product for synchronizing replicas of shared data structures associated with one or more computer systems. The method comprises: evaluating a metric for performing a replica synchronization operation on a first computer system according to a first synchronization method; evaluating the metric for performing a replica synchronization operation on the first computer system according to a second synchronization method; and, selecting, at synchronization time, based on the evaluated metric, whether to use the first or second synchronization methods, and communicating a command to a second computer system to replicate a shared data structure based on the selected synchronization method.
