Abstract: A device for cooking a starch-based food item is provided in which there is a drying cycle at a temperature below the gelatinization temperature and a cooking cycle at a temperature above the gelatinization temperature. The drying provides a relative weight drop by a first amount and the cooking provides a further relative weight drop. The weight is monitored during drying and cooking to provide feedback control of the duration of the drying and cooking times. The device and method make healthy food with reduced rapid digestible starch (RDS) and increased resistant starch (RS) content. In this way the glycemic index (GI) of a food item is reduced and the resistant starch is increased, which is beneficial to health especially for diabetes and obese groups.

Abstract: A compact Vertical Take-Off And Landing (VTOL) aircraft unit includes a duct fan including a propeller having a rotational axis which extends substantially vertically and discharges air downward to generate thrust sufficient for VTOL, an electric motor disposed above the duct fan and including an output shaft operatively connected to the propeller for rotating the propeller, and a cover disposed above the motor which is configured to support a load thereon. A gap is defined between the cover and the duct fan around an outer circumferential periphery of the aircraft and forms an opening of a primary flowpath for ambient air to the propeller, the primary flowpath for ambient air being non-parallel to the propeller's rotational axis.

Abstract: This invention discloses a bend insensitive single mode fiber, which is composed by a bare glass fiber with a round cross section and two resin protective layers with circular cross sections surrounding the outer of the bare glass fiber. It is characterized in that the bare glass fiber is composed by a core layer with a round cross section and two claddings with circular cross sections. The refractive index of the core layer is higher than the index of the two claddings and the refractive index difference between the core layer and the first cladding is larger than the difference between the first and second claddings. The second cladding is made of pure SiO2. The refractive index profile of the core layer follows a power function, and the refractive index profile of the two claddings follow a ladder-type distribution. The loss of the invented fiber is insensitive to the bending of the fiber, which meets the requirements of ITU.T G.657.A and G.657.B standards, respectively.

Abstract: A rail gun launcher consists of an armature where a magnetic core with a multiple turn conductive coil, two parallel conductive rails on which terminals of the coil contact and slide, and a non-magnetic conductive barrel enclosing the rails and the armature. The coil partially encloses the magnetic core to shift magnetic equilibrium. When an AC power source is connected to the rails, the coil generates a source magnetism around the coil as well as an induced magnetism on the conductive barrel in an opposite direction through the magnetic core. The source magnetism and the induced magnetism are shifted in magnetic equilibrium and in opposite direction thereby repelling the armature forward. This repulsive force travels with the armature and is continuous from breech to muzzle and propels the armature forward to a high velocity without control circuitry or commutation.
