Abstract:
A kinetic power generation unit (1,2,3) improves the magnetic field of an electric motor (1a) and the magnetic field of a power generator (1b) into a same magnetic field coupling of a same rotor (10), so that the rotors (10) of electric motor (la) and the power generator (1b) have the same rotational direction, and an exciting winding (12a) of the electric motor (1a) and a field winding (12b) of the power generator (1b) change and transmit phases sequentially to a phase voltage by a DC brushless drive controller (40), so that an interference effect on the counter electromotive force of the electric motor (1a) and the counter-electromotive force of the power generator (1b) is changed to a positive effect.

An anti-counterfeiting system includes an NFC tag attached to a product, a mobile device capable of sensing the NFC tag, and a server receiving and transmitting signals from and to the mobile device. The mobile device reads verifying codes of the NFC tag and generates a location data by a GPS unit, and then transmits the verifying codes and the location data to the server. The server verifies the verifying codes and the location data, and then transmits a message back to the mobile device and shows the verifying result on a display of the mobile display.
Abstract:
An illumination device for use with gas combustor, which includes an engage ring and at least one lamp. The outer circumference of the engage ring is formed with at least one pivotal seat, and the outer circumference of each of the at least one lamps is formed with a spherical shaft having the inclined angle being adjustable and pivotally connected in the pivotal seat. The illumination device is able to be rapidly connected to a conventional gas combustor, when the above two are combined as one piece, a light source of each of the at least one lamps can be turned on through adjusting the inclined angle of each of the at least one lamps relative to the engage ring, so the generated lights can be projected to the combusting location of the gas combustor to provide required illumination during the combustion operation.
Abstract:
A novel method and system for conducting wide-field multi-photon microscopy through plane-projection are provided. It has been discovered that the limitations of conventional temporal-focusing techniques, such as single excitation wavelength and low acquisition rates can be resolved utilizing a novel optical set-up in which an optical diffuser is used as the scatterer. The use of such an optical arrangement enables temporal focusing regardless of the central wavelength of laser pulses. In addition, the optical sectioning possible using the disclosed microscopy is comparable to confocal microscopy, and can be robustly achieved by both moderate and high NA objectives at 100-fs pulse width. Moreover, the multi-photon excitation efficiency of the disclosed system can be enhanced by lowering the repetition rate of the ultrafast laser light source at constant pulse width and average power.
Abstract:
A printed circuit board is disclosed. The printed circuit board comprises a substrate having a top surface and a bottom surface. A ground plane is on the bottom surface. A signal trace is on the top surface along a first direction. At least two isolated power planes are on the top surface adjacent to opposite sides of the signal trace, respectively. A conductive connection along a second direction couples to the two power planes, across the signal trace without electrically connecting to the signal trace, wherein the signal trace doesn't pass over any split of the ground plane.

Abstract:
The present invention provides a gas combustor having detachable combustion device, which includes: a housing having the interior installed with a base, and a combustion device. When the combustion device is inserted in an insertion slot of the housing, the upstream end of a mix pipe of the combustion device is airtightly inserted in a sleeve opening of the base, and a pair of locking sheets of the combustion device are moved along a pair of stopping protrusions of the housing and cross the pair of stopping protrusions, so a first spring between a lock button and a positioning seat of the combustion device is allowed to respectively be compressed for storing energy or stretched for releasing energy, and the pair of locking sheets are enabled to be abutted against inner edges of the pair of stopping protrusions, so an interference is generated for forming a locking and combining status.

Abstract:
A structure of high electron mobility transistor growth on Si substrate and the method thereof, in particular used for the semiconductor device manufacturing in the semiconductor industry. The UHVCVD system was used in the related invention to grow a Ge film on Si substrate then grow the high electron mobility transistor on the Ge film for the reduction of buffer layer thickness and cost. The function of the Ge film is preventing the formation of silicon oxide when growing III-V MHEMT structure in MOCVD system on Si substrate. The reason of using MHEMT in the invention is that the metamorphic buffer layer in MHEMT structure could block the penetration of dislocation which is formed because of the very large lattice mismatch (4.2%) between Ge and Si substrate.
