Abstract: A method of transferring mass of at least one solute between a liquid first phase and a fluid second phase that is immiscible with the first phase, the method comprising moving at least one droplet of said liquid first phase in a microfluidic device by using electric-type forces (electrowetting or dielectrophoresis) within a space that is filled with said fluid second phase. Said droplet is preferably moved by said electric-type forces along a path between a point for injecting said droplet into said microfluidic device, and an extraction and/or analysis zone, said path being defined in such a manner that said droplet sweeps through a significant fraction of said space filled with said fluid second phase. The method may include a step of transferring said droplet using said electric-type forces to a chemical analysis device integrated in said microfluidic device, and a step of chemically analyzing said droplet. The invention also provides a device for implementing such a method.

Abstract: In a sphere decoding process, P PPM symbols emitted simultaneously are represented by a point of the modulation product constellation in a space of signals transmitted of dimension MP decomposed into P layers, each layer representing M modulation positions. The signal received is transformed into a representative point. The point of the product constellation closest to the received point within a sphere of given quadratic radius is determined. For each layer of rank p, ZF-DFE equalization is carried out; sorting in a list of the M PPM symbols as a function of the contributions that they would make to the quadratic distance to the received point is then carried out, followed by selection of the PPM symbol making the lowest contribution. The contribution is added to those from previous layers to obtain a sum of contributions. These steps are repeated until the lowest layer is attained.

Abstract: The present invention provides a method of generating mutually orthogonal reference signals for different user terminals in and OFDM system that span different but overlapping subcarriers. The subcarriers allocated to the user terminals are divided into a plurality of non-overlapping subcarrier blocks. Each user terminal is then allocated one or more subcarrier blocks. For each subcarrier block, a user terminal is assigned a reference signal comprising a base reference sequence and a linear phase rotation. To ensure mutual orthogonality among all user terminals, user terminals allocated the same subcarrier block use the same base reference sequence with different linear phase rotations.

Abstract: Apparatus and methods provide a kit for converting a conventional mortar round into a glide bomb. Mortar rounds are readily available to combat personnel and are small and light enough to be carried by relatively small unmanned aerial vehicles (UAVs) such as the RQ-7 Shadow. Advantageously, the kit provides both guidance and relatively good standoff range for the UAV such that the kit-equipped mortar round can be dropped a safe distance away from the intended target so that the UAV is not easily observed near the intended target.
