Active optical fiber and method for fabricating an active optical fiber

A section of active optical fiber (11) which comprises an active core (1), an inner cladding layer (2) and an outer cladding layer (3). The diameter of said core 1) and the thickness of said inner cladding (2) change gradually along the length of said section of active optical fiber (11). This forms tapered longitudinal profile enabling a continuous mode conversion process along the length of the section of fiber (11). The method for fabricating a section of tapered active optical fiber comprises the steps of fabricating a preform for drawing active optical fiber from said preform, installing said preform into a drawing tower, drawing optical fiber in said drawing tower and altering at least one of the two parameters including the take-off preform speed and the take-up fiber speed during drawing of the optical fiber.

Two-compartment reduced volume infusion pump

An implantable infusion apparatus has a medication reservoir for storing a medication and a carrier reservoir for storing a carrier. The entire apparatus, including both reservoirs, is typically located in a housing made of stainless steel, titanium, or any other strong corrosion resistant biocompatible material. The medication and carrier reservoirs are accessed through a medication access port and a carrier access port, respectively. The access ports are covered with a medication compound septum and a carrier compound septum, respectively. The carrier reservoir is larger, and thus holds a larger volume, than the medication reservoir. To reduce the size of the implantable infusion apparatus, the medication is highly concentrated to many times the dosage required. The concentrated medication is then diluted with the carrier, to the proper dose, before it is discharged to the patient.

Scanner/optical system for three-dimensional lidar imaging and polarimetry

An optical scanner system for contiguous three-dimensional topographic or volumetric imaging of a surface from an aircraft or spacecraft is disclosed. A servo controller synchronizes the rotation rates of a pair of wedge scanners with high precision to the multi-kilohertz laser fire rate producing an infinite variety of well-controlled scan patterns. This causes the beam pattern to be laid down in precisely the same way on each scan cycle, eliminating the need to record the orientations of the wedges accurately on every laser fire, thereby reducing ancillary data storage or transmission requirements by two to three orders of magnitude and greatly simplifying data preprocessing and analysis. The described system also uses a holographic element to split the laser beam into an array that is then scanned in an arbitrary pattern. This provides more uniform signal strength to the various imaging detector channels and reduces the level of optical crosstalk between channels, resulting in a higher fidelity three-dimensional image.

Fluid sampling, analysis and delivery system

The lack of safe, reliable, automated and clinically acceptable blood sampling has been the main problem precluding the development of real-time systems for blood analysis and subsequent closed-loop physiological function control. While the analysis of a static blood sample in laboratory conditions has been rapidly advancing in reliability and blood volume reduction, non-invasive real-time blood analysis performed in vivo (while the blood is circulating in the body) has been elusive and unreliable. In this study we propose an innovative idea for semi-invasive blood sampling and analysis, which resembles the operation of a mosquito. At a miniature scale the proposed system does penetrate the skin to extract a static blood sample for further analysis, but the extent of this penetration, and the fact that it can be made painless, is particularly attractive for such applications as automated glucose analysis for closed-loop control of insulin infusion (artificial pancreas), continuous drug monitoring, or even periodic DNA analysis for security and identification purposes. These design aspects are described, and a specific implementation, applying MEMS (Micro Electro Mechanical Systems) technology, is suggested. The proposed microsystem is a matrix of individually controllable e-Mosquito™ cells, packaged in a disposable patch and attached to the skin, could be an avenue for real-time semi-invasive blood analysis and diagnostics.

The power generation system further includes a heat reclaiming loop having a fluid that extracts heat from the turbine loop. The fluid of the heat reclaiming loop is then raised to a higher temperature and then placed in heat exchange relationship with the working fluid of the turbine loop. The power generating system is capable of using low temperature waste heat is approximately of 150 degrees F. or less. The turbine includes one or more blades mounted on a rotating member. The turbine also includes one or more nozzles capable of introducing the gaseous working fluid, at a very shallow angle on to the surface of the blade or blades at a very high velocity. The pressure differential between the upstream and downstream surfaces of the blade as well as the change in direction of the high velocity hot gas flow create a combined force to impart rotation to the rotary member.
