Abstract:
A lathe includes a machine support, a working table positioned on the machine support, a rotating driver, a moving device, and a feeding device. The rotating driver rotates the work table. The moving device includes at least one cross beam, at least one first driving mechanism, and at least one second driving mechanism. The cross beam is movably positioned on the machine support above the working table. The feeding device is movably positioned on the at least one cross beam, and includes a feeding driving mechanism and a cutter. The first driving mechanism drives the cross beam to move along a first direction, and the second driving mechanism drives the feeding device to move along a second direction at about ninety degrees from the first direction. The feeding mechanism drives the cutter to move backwards and forwards along a third direction perpendicular to the first and second direction.
Abstract:
A nanostructure includes a plurality of metal nanoblades positioned with one edge on a substrate. Each of the plurality of metal nanoblades has a large surface area to mass ratio and a width smaller than a length. A method of storing hydrogen includes coating a plurality of magnesium nanoblades with a hydrogen storage catalyst and storing hydrogen by chemically forming magnesium hydride with the plurality of magnesium nanoblades.
Abstract:
A tracking detection and alarm method which is applied to a navigation device use a number of positioning data points retrieved from a navigation module of the navigation device. A number of deflections and a number of average speeds that correspond to the position data points are calculated and generated. A number of maximum deflections are calculated and generated according to the average speeds. When a deflection of a positioning data point is greater than a maximum safe deflection thereof, one is added to a frequency of unsafe driving instances. When the frequency of unsafe driving instances is greater than a preset threshold value, an unsafe driving alarm is activated.
Abstract:
An apparatus and method for forwarding a web address to another web address is presented. A web forwarder receives a request destined to a first web address including at least a domain name. The web forwarder then determines a forwarding uniform resource locator (URL) that corresponds to the domain name and redirects the request to a second web address that corresponds to the forwarding URL.
Abstract:
A connector, comprising an insulative body, a plurality of conduction terminals, and a shielding shell. The tongue panel of the insulative body comprises a first surface and a second surface. The conduction terminals are arranged as first conduction terminals in the front row and second conduction terminals in the back row, the first conduction terminals comprising a first contact portion, a bending portion bent A and extended from the rear edge of the first contact portion, a first fixing portion and a first welding portion. The first surface of the tongue panel is provided with a first receiving slot for receiving the first fixing portion and a recess portion disposed at the front end of the first receiving slot, the recess portion is formed as an opening for the first contact portion to nm through the opening from the first surface to be fixed onto the second surface.
Abstract:
An electro-magnetic wave filtering and impeding board is made of metal and includes a first side and a second side. The first side has multiple linear slots and the second side includes multiple concaved geometric holes which communicate with the linear slots. The electro-magnetic waves are impeded by the metallic material and weakened when passing through the linear slots and the geometric holes so as to impede the electro-magnetic waves.
Abstract:
A driving method for driving a display apparatus is provided. The driving method includes: configuring a plurality of driving voltages corresponding to a plurality of gray scales, where the gray scales include a first gray scale and a second gray scale smaller than the first gray scale, and a first driving voltage corresponding to the first gray scale is lower than a second driving voltage corresponding to the second gray scale; and controlling the display apparatus to display a gray scale merely up to the second gray scale. In this way, the driving method hence reduces the response time of the display apparatus, which may be an LCD display panel.
Abstract:
A light emitting diode package for one or more light emitting diodes mounted on a substrate. A frame is disposed on at least a portion of the substrate and substantially surrounds, but does not contact, the light emitting diode. The frame is substantially transparent to light emitted from the light emitting diode and includes one or more first wavelength converting materials. The wavelength converting materials, which may be one or more phosphors, convert at least a portion of light emitted at the emission wavelength to different wavelength. A cover covers the light emitting diode within the frame. The cover layer includes one or more second wavelength converting materials differing from the first one or more wavelength converting materials in wavelength converting material concentration or in converted light wavelength or in combinations of wavelength converting materials.
Abstract:
A drainage device for draining liquid out of a closed chamber includes an air cylinder, a driving assembly, a first channel, a second channel, a first sealing assembly, a second sealing assembly, and a controller. The air cylinder includes a main body defining a receiving chamber, an action piston positioned in the receiving chamber of the main body, and a connecting rod connected to the action piston. The main body defines a liquid inlet and a liquid outlet, both of which communicate with the receiving chamber, and the presence of a fixed piston with a seal in each of the inlet and outlet creates a double-acting one-way valve when the action piston is moved up and down.
Abstract:
