    摘要： A delay filter uses the dielectric mono-block triple-mode resonator and unique inter-resonator coupling structure, having smaller volume and higher power handling capacity. The triple-mode mono-block resonator has three resonators in one block. An input/output probe is connected to each metal plated dielectric block to transmit microwave signals. Corner cuts couple a mode oriented in one direction to a mode oriented in a second, mutually orthogonal direction. An aperture between two blocks couples all six resonant modes, and generates two inductive couplings by magnetic fields between two modes, and one capacitive coupling by electric fields. The input/output probes, coupling corner cuts and aperture are aligned such that all six resonators are coupled in the desired value and sign, so constant delay on the transmitted signal within certain bandwidth can be achieved. By connecting the input and output probes to the base printed circuit board, the delay filter is surface mountable.

    摘要： A method, device and electronic terminal for unlocking are disclosed. The method is applicable in the electronic terminal. The electronic terminal comprises a touch display unit and receives a touch input operation of a user via the touch display unit. When the electronic terminal is in a user interface lock state, an operation that an operating body made on the touch display unit is detected; a response is made to the operation, a sliding track is formed on the touch display unit, and the time for forming the sliding track is recorded; the distance of the sliding track is calculated; the velocity for forming the sliding track is calculated on the basis of the distance and of the time; whether or not the velocity is greater than or equal to a predetermined velocity is determined; and, when the velocity is greater than or equal to the predetermined velocity, the user interface lock state is deactivated. The disclosure greatly reduces the technical complexity of unlocking by eliminating the need to set a predetermined track and a predetermined target on an unlocking interface.

    摘要： A system is disclosed for ejecting a semiconductor die from a tape to which the die is affixed during the wafer dicing process. In embodiments, the system includes an ejector tool including a support table, ejector pins and a pick-up arm. The support table is connected to a vacuum source for creating a negative pressure at an interface between the tape and support table. The support table further includes an aperture with one or more chamfered sidewalls. The vacuum source is connected to the aperture so that, upon placement of the tape on the support table with a die centered over the aperture, the vacuum source pulls a portion of the tape around the edges of the semiconductor die away from the die and into the space created by the chamfered edges.

    摘要： A microwave filter and method for remotely tuning a microwave filter from one sub-band to another sub-band using metallic rings to adjust the capacitance or inductance of the resonator. In adjusting the capacitance, a plurality of metallic rings are disposed in the upper section or end of the resonator. Each ring has an RF switch that connects or disconnects each ring to ground, thereby varying the capacitance of the resonator. In adjusting the inductance, a plurality of metallic rings are disposed perpendicular to the magnetic field of the resonator. Each ring has an RF switch disposed within the electrical path of the ring that opens or closes the electrical path of each ring. By opening and closing each ring, the magnetic field of the resonator is altered, thereby varying the inductance of the resonator.

    摘要： The present invention incorporates triple-mode, mono-block resonators that are tunable. Four novel and unobvious methods of tuning are disclosed. The first tuning method is to mechanically grind areas on three orthogonal faces of the mono-block in order to change the resonant frequencies of the three modes in each block. Another method of tuning frequency is to cut a slot within a face of the resonator. A third method of tuning the mono-block is to tune the resonant frequency of a particular mode by removing small circular areas of the conductive surface from a particular face of the mono-block. The fourth, tuning method is the use of discrete tuning elements, with 3 elements distributed among three orthogonal faces of the mono-block, to affect the necessary change of the resonant frequencies.
