Abstract: Blind polarization demultiplexing algorithms based on complex independent component analysis (ICA) by negentropy maximization for quadrature amplitude modulation (QAM) coherent optical systems are disclosed. The polarization demultiplexing is achieved by maximizing the signal's non-Gaussianity measured by the information theoretic quantity of negentropy. An adaptive gradient optimization algorithm and a Quasi-Newton algorithm with accelerated convergence are employed to maximize the negentropy. Certain approximate nonlinear functions can be substitutes for the negentropy which is strictly derived from the probability density function (PDF) of the received noisy QAM signal with phase noise, and this reduces the computational complexity. The numerical simulation and experimental results of polarization division multiplexing (PDM)-quadrature phase shift keying (QPSK) and PDM-16QAM reveal that the ICA demultiplexing algorithms are feasible and effective in coherent systems and the simplified ones can also achieve equivalent performance. Blind polarization demultiplexing algorithms based on complex independent component analysis (ICA) by negentropy maximization for quadrature amplitude modulation (QAM) coherent optical systems are disclosed.

Abstract: Disclosed is a method for preparing thermoplastic polymer foamed beads, comprising the following steps: 1) putting polymer particles into a sealed container heated to a foaming temperature, and putting the sealed container in a vacuum environment; 2) introducing a supercritical fluid into the sealed container, and performing swelling diffusion; 3) after 5-60 minutes of swelling diffusion of the supercritical fluid, releasing the pressure of the sealed container to discharge the supercritical fluid, and inducing nucleation and growth of foam pores by controlling the pressure release velocity so as to enable the polymer beads to swell and grow; 4) leading the polymer beads inside the sealed container into a vacuum environment to further swell and grow, finally obtaining the polymer foamed beads with a high foaming ratio. The foaming temperature in step 1) is a temperature where the polymer particles can undergo plastic deformation but cannot flow yet; the foaming temperature is within Tg to Tg+40°C for an amorphous polymer, and Tg is a glass transition temperature of the amorphous polymer; for a crystalline polymer, the foaming temperature is within Tm-20°C to Tm, and Tm is the melting point of the crystalline polymer.

Abstract: A mandrel-pulling distance sensing assembly of an electric rivet gun is mounted in a barrel of a housing and has a stationary seat, a moving seat, two magnetic elements separately fixed on the stationary seat, and a Hall effect sensor fixed on the moving seat. The moving seat is driven by a driving assembly of the electric rivet gun and is movable relative to the stationary seat. While the Hall effect sensor moves along with the moving seat between the two magnetic elements, the Hall effect sensor detects a changing magnetic field and produces and outputs a changing voltages to a control unit to allow the control unit to operate the driving assembly according to the changing voltages. Thus, the moving seat can be accurately positioned and moving ranges of a snapping device that is driven by the driving assembly can be accurately controlled.

Abstract: A native tensor processor calculates tensor contractions using a sum of outer products. In one implementation, the native tensor processor preferably is implemented as a single integrated circuit and includes an input buffer and a contraction engine. The input buffer buffers tensor elements retrieved from off-chip and transmits the elements to the contraction engine as needed. The contraction engine calculates the tensor contraction by executing calculations from an equivalent matrix multiplications, as if the tensors were unfolded into matrices, but avoiding the overhead of expressly unfolding the tensors. The contraction engine includes a plurality of outer product units that calculate matrix multiplications by a sum of outer products. By using outer products, the equivalent matrix multiplications can be partitioned into smaller matrix multiplications, each of which is localized with respect to which tensor elements are required. A native tensor processor calculates tensor contractions using a sum of outer products. In one implementation, the native tensor processor preferably is implemented as a single integrated circuit and includes an input buffer and a contraction engine.
