Abstract: A novel form of an integrated variable inductor uses an on-chip transformer together with a variable capacitor. The variable capacitor can either be a varactor or a switched capacitor array and is connected to the secondary coil of the transformer. By changing the capacitance at the secondary coil of a transformer, the equivalent inductance looking into the primary coil of the transformer can be adjusted. With another capacitor in parallel to the primary coil, two different modes of resonance inherently exist, and a very wide frequency tuning range can be achieved by combining the two modes.

Abstract: This invention relates to a novel soy isoflavone product with high purities and strong biological activities and the method of producing the same from natural soybeans, soybean materials (i.e. tofu dregs, soy molasses) and other plant sources. The method includes three steps consisting of extraction with an organic solvent, hydrolysis using an acid and crystallization using an antisolvent. The procedure is very simple and thus can be easily adapted for large-scale manufacturing. Moreover, the procedure is able to produce a high yield of total isoflavones at a lower cost. HPLC analysis and E-Screen bioassay reveal that the obtained product not only contains a high content of isoflavone aglycones by weight of dry matter but also exhibits strong estrogenic activity toward human cells. Therefore, the product should be efficacious for relieving menopausal symptoms and other estrogen-deficient diseases and can be used in health care supplements or as additives for foods, beverages or cosmetics.

Abstract: A single inductor multiple-input multiple-output (SI-MIMO) switching converter time-multiplexes different input power sources through only one inductor to provide multiple regulated output voltages, which can be used to power up different blocks of a portable electronic device (or whatever else it is used for) and at the same time to charge up a rechargeable battery. Power multiplexing is achieved by input switches that are also the switching elements of the switching converter, thus eliminating an additional power multiplexer.

Abstract: An End-Point Prediction scheme is described for voltage-mode buck regulators to generate adaptive output voltage to integrated-circuit systems. Internal nodal voltages of the regulator controller are predicted and set automatically by the proposed algorithms and circuits. The settling time of the regulator can therefore be significantly reduced for faster dynamic responses, even with dominant-pole compensation.

Abstract: A technique has been developed to fabricate micro- or nanopumps based on porous alumina thin films. The main body of the nanopump consists of a porous alumina thin film (containing nano-sized channels of about 40-300 nm in diameter) with conductive surfaces (e.g. Au coating layers) on both sides of the film. Through the fabrication of nanochannels in (the alumina films) and the subsequent annealing and surface activation processes, high-efficiency micro- or nanopumps can be made. The nanofluidic flow through the nanochannels of the alumina thin films is driven by an electric field with no moving parts. The flow rate (up to 50 millilitres/(min·cm2)) of water through the alumina thin film can be continuously tuned through the intensity of the electric field, i.e., the DC electric potential applied across the nanochannels.

Abstract: A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a sufficiently high frequency without affecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substantially relaxed.

Abstract: Crystallization-inducing metal elements are introduced onto an amorphous silicon thin film. A first, low-temperature, heat-treatment induces nucleation of metal-induced crystallization (MIC), resulting in the formation of small polycrystalline silicon “islands”. A metal-gettering layer is formed on the resulting partially crystallized thin film. A second, low-temperature, heat-treatment completes the MIC process, whilst gettering metal elements from the partially crystallized thin film. The process results in the desired polycrystalline silicon thin film.

The emissive units comprise at least a hole-transport layer and an electron-transport layer. An intermediate layer is disposed between two adjacent emissive units and the intermediate layer comprises at least two sub-layers, a first sub-layer being formed of a material that can inject electrons into one emissive unit and a second sub-layer being formed of a material that can inject holes into the adjacent emissive unit. The sub-layers are formed of metals or inorganic materials only and a surface of the intermediate layer may be treated by a low pressure CF4-plasma.

Abstract: A method and apparatus for providing streaming data to multiple clients involves the provision of intelligent gateway at the edge of a network. The gateway is designed so that if it receives a request from a second client within the network for a data stream already being supplied to a first client in the network, that data stream is duplicated by the gateway rather than making a second request for the same stream from a server. Multiple such gateways can be combined to form a large load balancing network. An important aspect of the invention is a software interface in the gateway that enables a data packet address type to be changed from unicast to multicast and vice versa.
