Abstract: There is described a method for interrogating optical fiber comprising fiber Bragg gratings (“FBGs”), using an optical fiber interrogator. The method comprises (a) generating an initial light pulse from phase coherent light emitted from a light source, wherein the initial light pulse is generated by modulating the intensity of the light; (b) splitting the initial light pulse into a pair of light pulses; (c) causing one of the light pulses to be delayed relative to the other of the light pulses; (d) transmitting the light pulses along the optical fiber; (e) receiving reflections of the light pulses off the FBGs; and (f) determining whether an optical path length between the FBGs has changed from an interference pattern resulting from the reflections of the light pulses.

Abstract: A clearance control assembly for a gas turbine engine that defines an axial direction and a radial direction and includes a stage of rotor blades and a shroud hanger. The assembly includes a case configured to be positioned outward along the radial direction from the stage of rotor blades when installed in the gas turbine engine. The case is further configured to be engaged with the shroud hanger at a first location when installed in the gas turbine engine. The assembly also includes a baffle positioned outward along the radial direction from the case to define a chamber therebetween. The baffle has a forward end and an aft end. The forward end of the baffle is engaged with the case to form a first seal and the aft end of the baffle is engaged with the case to form a second seal. The baffle, the case, or both define an inlet to allow a fluid to enter the chamber and the case defines an outlet to allow the fluid to exit the chamber.

Abstract: A receiver has a sample rate converter that outputs samples of orthogonal frequency division multiplexing symbols. The receiver includes a fast Fourier transform engine that receives the samples and converts them into a plurality of frequency domain sub-carriers. A timing control circuit generates a timing error and controls the sample rate converter to adjust a sample rate of the orthogonal frequency division multiplexing symbols based at least in part on the timing error.

Abstract: A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.

Abstract: Apparatus, methods, and computer-readable medium are disclosed for controlling positioning of a desk. An exemplary apparatus includes a tabletop, expandable legs, motors, position sensors, a processor, and a memory configured to store instructions. The motors alter a length of one of the expandable legs. The position sensors identify current position of each of the plurality of expandable legs. The instructions cause the processor to receive a sensor signal, a communication signal, or a command signal, receive the identified current position of one or more of the expandable legs, determine a projected length value for the one or more expandable legs responsive to the received sensor signal, the communication signal, or the command signal, and command one or more of the plurality of motors based on the projected length value for the one or more expandable legs and the identified current position of the one or more expandable legs.

Abstract: Methods, systems, and tables are disclosed for charging multiple devices on a surface and providing feedback. An exemplary method includes sensing a location of a wirelessly rechargeable device on a charging surface of the wirelessly charging surface device and wirelessly powering the wirelessly rechargeable device via a portion of the charging surface corresponding to the sensed location of the wirelessly rechargeable device. The method also includes receiving charging status information from the wirelessly rechargeable device and outputting a human perceptible indication responsive to the received charging status information and the sensed location of the wirelessly rechargeable device.

Abstract: A personal Wallet and Purse Medication Card apparatus, which is, at most, the dimensions of a credit card, with a front surface and a back surface opposite the front surface. The card has at least one sealed cavity designed for securely housing generic, as-needed medication that does not more than marginally protrude beyond the front surface, is generally the dimensions of a credit card, and intended to fit within modern-day clothing, a personal wallet, or purse.

Abstract: A user of a personal computing device may identify multiple travel items of interest displayed for purchase by a network-based travel service. However, the user may not desire to purchase the travel items in a single purchase. Upon making a travel purchase that includes a first travel item that does not include a second travel item corresponding to the first travel item, the user may employ the network travel package service to search for second travel items corresponding to the first travel item, select from discounted travel packages including the first travel item and second travel items returned from the search, and purchase a discounted travel package. Beneficially, multiple travel items may be purchased separately while obtaining a package discount as compared to the stand-alone price of the travel items.
