Abstract: A method of tracking an inventory of objects via a mobile communications device includes acquiring an image of one or more of the objects via the mobile communications device, which also collects a location of the mobile communications device while acquiring the image of the one or more of the objects. The location and image are transferred from the mobile communications device to a remote server via a wireless network, such that the one or more of the objects are identified at the server based on the image, and the location and identity of the one or more objects are stored on a database associated with the server.

Abstract: The present invention provides a method, device and a computer program for haplotyping single cells, such that a sample taken from a pregnant female, without directly sampling the fetus, provides the ability to non-invasively determine the fetal genome. The method can be performed by determining the parental and inherited haplotypes, or can be performed merely on the basis of the mother's genetic information, obtained preferably in a blood or serum sample. The novel device allows for sequence analysis of single chromosomes from a single cell, preferably by partitioning single chromosomes from a metaphase cell into long, thin channels where a sequence analysis can be performed.
Abstract: Compact laser systems are disclosed which include ultrafast laser sources in combination with nonlinear crystals or waveguides. In some implementations fiber based mid-IR sources producing very short pulses and/or mid-IR sources based on a mode locked fiber lasers are utilized. Some embodiments may include an infrared source with an amplifier system comprising, in combination, a Tm fiber amplifier and an Er fiber amplifier. A difference frequency generator receives outputs from the Er and/or Tm amplifier system, and generates an output comprising a difference frequency. Exemplary applications of the compact, high brightness mid-IR light sources include medical applications, spectroscopy, ranging, sensing and metrology.

Abstract: It has been discovered that inhibiting mitochondrial respiration in platelets reduces platelet activation or platelet aggregation. Certain heterocyclic compounds significantly reduced one or more platelet functions including clumping, sticking or platelet-stimulated clotting. Thus diseases or disorders mediated by inappropriately high levels of platelet activation or platelet aggregation can be treated by administering a therapeutically effective amount of a heterocyclic compound or nonheterocyclic mitochondrial inhibitor that significantly reduces one or more platelet functions including clumping, sticking or platelet-stimulated clotting, preferably in a reversible manner.

Abstract: Various methods for tracking and recognition with rotation invariant feature descriptors are provided. One example method includes generating an image pyramid of an image frame, detecting a plurality of interest points within the image pyramid, and extracting feature descriptors for each respective interest point. According to some example embodiments, the feature descriptors are rotation invariant. Further, the example method may also include tracking movement by matching the feature descriptors to feature descriptors of a previous frame and performing recognition of an object within the image frame based on the feature descriptors. Related example methods and example apparatuses are also provided.

Abstract: This invention provides a method of forming semiconductor films on dielectrics at temperatures below 400° C. Semiconductor films are required for thin film transistors (TFTs), on-chip sensors, on-chip micro-electromechanical systems (MEMS) and monolithic 3D-integrated circuits. For these applications, it is advantageous to form the semiconductor films below 400° C. because higher temperatures are likely to destroy any underlying devices and/or substrates. This invention successfully achieves low temperature growth of germanium films using diboran. First, diboran gas is supplied into a reaction chamber at a temperature below 400° C. The diboran decomposes itself at the given temperature and decomposed boron is attached to the surface of a dielectric, for e.g., SiO2, forming a nucleation site and/or a seed layer. Second, source gases for semiconductor film formation, for e.g., SiH4, GeH4, etc., are supplied into the chamber, thereby forming a semiconductor film.
Abstract: A method and apparatus are provided for a fluid level insertion indicator that provides immediate feedback to a surgeon by draining when a tip of a needle has entered a body lumen, such as peritoneal cavity. An apparatus includes a handle connected to a hollow needle and a hollow stylet that extends through the hollow needle and has a blunt distal end that includes an opening for passing fluid. A spring biases the stylet to extend past the sharp distal end of the needle absent resistance by tissue against the stylet. An at least partially translucent pressure chamber configured to hold a quantity of fluid under pressure is connected to the proximal end of the stylet. The pressure chamber and stylet form a conduit for passing fluid through the opening in the blunt distal end when the stylet extends past the sharp distal end of the hollow needle.

Abstract: A method of use of an activatable bioluminescent probe system includes: providing a bioluminescent protein and a quencher in a reaction environment; modifying a ligand between the quencher and the bioluminescent protein using a ligand interacting molecule; adding a bioluminescence initiating molecule to the reaction environment; and measuring light originating from the interaction between the bioluminescent protein and the bioluminescence initiating molecule.
Abstract: Techniques for an analog-to-digital converter (ADC) using pipeline architecture includes a linearization technique for a spurious-free dynamic range (SFDR) over 80 deciBels. In some embodiments, sampling rates exceed a megahertz. According to a second approach, a switched-capacitor circuit is configured for correct operation in a high radiation environment. In one embodiment, the combination yields high fidelity ADC (>88 deciBel SFDR) while sampling at 5 megahertz sampling rates and consuming <60 milliWatts. Furthermore, even though it is manufactured in a commercial 0.25-?m CMOS technology (1 ?m=12?6 meters), it maintains this performance in harsh radiation environments. Specifically, the stated performance is sustained through a highest tested 2 megarad(Si) total dose, and the ADC displays no latchup up to a highest tested linear energy transfer of 63 million electron Volts square centimeters per milligram at elevated temperature (131 degrees C.) and supply (2.7 Volts, versus 2.5 Volts nominal).

Abstract: An improved method and apparatus for respiratory audio-visual biofeedback are disclosed. A guide patterned after a breathing cycle comfortable to the patient serves as a target. The target is displayed as a bar moving vertically upward during inhale and vertically downward during exhale, between fixed end ex-hale and end in-hale limits. The patient's current respiratory position is also displayed as a bar, oriented parallel to the target bar so that the difference between the current position and the target position is easy for the patient to see.
