Abstract:
A mask at frequency domain comprises a plurality of amplitude patterns positioned on a first surface of the mask and a plurality of phase patterns positioned on a second surface of the mask. The amplitude patterns have different vertical thicknesses to change the amplitude of an exposing light, and the phase patterns have different vertical thicknesses to change the phase of the exposing light. Preferably, the amplitude patterns are made of inorganic material, such as molybdenum silicide (MoSi), and the phase patterns are made of transparent material, such as quartz. The amplitude patterns and phase patterns are the Fourier transform of a circuit layout, and their numbers and positions are correspondent with each other.
Abstract:
The present invention provides a method for mass producing any metal alloy. After melting a metal mixture, a mixture of heating, soaking and/or cooling is processed to obtain the alloy even with a trace element added. The metal alloy made by the present invention thus has a high purity and a low cost.

An apparatus of processing an input signal generated according to accessing of an optical storage medium is disclosed. The apparatus has a detecting circuit and a decision logic. The detecting circuit is coupled to the input signal for detecting a target peak value and a target bottom value of the input signal within a time period, wherein the time period is not less than a period of a reference signal generated according to accessing of the optical storage medium. The decision logic is coupled to the detecting circuit for determining a reference level according to the target peak value and the target bottom value.
Abstract:
For object detection, a two-step group scan to the traces of a capacitive touch sensor is performed, thereby dramatically shortening the overall scanning time and reducing noise effect. After all the traces are scanned by the pre-scan step to find out the trace of a touch point, the trace of the touch point and traces adjacent thereto are scanned by the re-scan step for more accurate positioning of the touch point.
Abstract:
The invention discloses a method and a module for measuring rotation and a portable apparatus comprising said module. The module of the present invention is adapted for measuring rotation of a target, and the module includes a first sensor, a second sensor and a processor. The first sensor is disposed at a first location of the target, for sensing a first centripetal acceleration and a first tangential acceleration when the target is rotated. The second sensor is disposed at a second location of the target, for sensing a second centripetal acceleration and a second tangential acceleration when the target is rotated. The processor is coupled to the first sensor and the second sensor, for receiving the first centripetal acceleration and the first tangential acceleration from the first sensor, receiving the second centripetal acceleration and the second tangential acceleration from the second sensor, and calculating the rotation angle of the target accordingly.
Abstract:
An optical fiber connector includes a shell, a lens and a strengthening unit. The shell includes a blind hole extended along a first direction for receiving a fiber and a through hole communicated with the blind hole and extended along a second direction perpendicular to the first direction. The lens is formed on the shell to align with a bottom of the blind hole. The lens is capable of optically coupling with the fiber in the blind hole. The strengthening unit is formed in the through hole.
Abstract:
A pneumatic spanner structure includes a head body, a link bevel gear unit, a hit unit and a driving handle. A driving motor axle portion at an open end of the driving handle drives a motor link bevel gear post and a hit unit link bevel gear plate of the link bevel gear unit. The hit unit link bevel gear plate links the hit unit. The link bevel gear unit enhances and transmits the force to the hit unit. The hit unit applies the acting force on a workpiece. The hit unit doesn't need a buffer space for actuation and the force is indirect. The link bevel gear unit is a deceleration device to extend the service life of the whole structure. The output force is more powerful than the prior art, providing a stable and compact structure.
Abstract:
Connection establishing management methods for traversing network address translation (NAT) routers and firewalls between network terminal devices to establish a connection channel therebetween for use in a network system including at least first, second and third network terminal devices and a traversal server are disclosed. First, when traversal server receives a call request of first and second network terminal devices, network topology levels of first and second network terminal devices are detected to detect whether first and second network terminal devices are located behind NAT router and/or firewall. Then, one of first and second network terminal devices or third network terminal device is selected according to the detection result such that selected network terminal device acted as proxy server for the traversal server to establish a connection channel corresponding to call request between first and second network terminal devices.
Abstract:
Data management methods for use in a network system including at least first, second and third network terminal devices and traversal server are disclosed. First and second network terminal devices can traverse at least one NAT router and/or firewall to establish a connection channel between each other for data access through traversal server. The method includes the steps of: receiving first packet with first protocol format from first network terminal device; determining whether to perform protocol conversion operation; if so, obtaining a list of available network terminal devices, assigning first network terminal device from obtained list, converting first packet with first protocol format into second packet with second protocol format that is decodable by second network terminal device, and sending second packet to second network terminal device such that second network terminal device can obtain content of first packet by decoding second packet upon reception of second packet.
