Abstract: Various schemes pertaining to pre-encoding processing of a video stream with motion compensated temporal filtering (MCTF) are described. An apparatus determines a filtering interval for a received raw video stream having pictures in a temporal sequence. The apparatus selects from the pictures a plurality of target pictures based on the filtering interval, as well as a group of reference pictures for each target picture to perform pixel-based MCTF, which generates a corresponding filtered picture for each target picture. The apparatus subsequently transmits the filtered pictures as well as non-target pictures to an encoder for encoding the video stream. Subpictures of natural images and screen content images are separately processed by the apparatus.

Abstract: A semiconductor device including a first die and a second die bonded to one another. The first die includes a first passivation layer over a substrate, and first bond pads in the first passivation layer. The second die includes a second passivation layer, which may be bonded to the first passivation layer, and second bond pads in the second passivation layer, which may be bonded to the first bond pads. The second bond pads include inner bond pads and outer bond pads. The outer bond pads may have a greater diameter than the inner bond pads as well as the first bond pads.

The magnetic core includes a first outer column, a second outer column, an upper cover and a lower cover. The first outer column and the second outer column are disposed between the upper cover and the lower cover. The primary side winding is disposed on the first outer column and the second outer column, and the plurality of secondary side windings are disposed on the first outer column and the second outer column. Each of the secondary windings has one end passing through a region between the first outer column and the second outer column.

Abstract: An electronic package and a method for fabricating the same are provided. A plurality of electronic components are disposed in a packaging structure. At least one antenna structure is stacked via a plurality of conductive elements on the packaging structure. The antenna structure is electrically connected to at least one of the electronic components. The electronic components have different radio frequencies. In mass production, the antenna structures of different antenna types are stacked on the packaging structure, and a radio frequency product of various frequencies can be produced. Radio frequency chips of different frequencies need not be fabricated into a variety of individual packaging modules. Therefore, the production cost is reduced, and the production speed is increased.

Abstract: A welding wire feeding device includes a base, a fixing post, a pressing member, a motor, and a conveying mechanism. The pressing member is pivotally connected with a driven wheel. A tension spring is provided between the fixing post and the pressing member. A shaft portion of the motor is pivotally connected with a driving wheel. The conveying mechanism is coupled to the base and has an air hole. The base is formed with a first passage and a second passage connected with a gas cylinder. The length of the conveying tube of the conveying mechanism can be adjusted by pressing. A wire is sandwiched between the driving wheel and the driven wheel through the tension spring. The motor drives the driving wheel to rotate the driven wheel so as to continuously convey the wire; meanwhile, the inert gas can be sent out through the second passage and the conveying mechanism to prevent a workpiece from being oxidized.

Abstract: A modulus address generator calculates the next address to access from a current address of a circular buffer having a length L and an address shift from the current address to the next address to access. Within the circuit of the modulus address generator, a plurality of registers stores the length L of the circular buffer, the current address, and the address shift. A separator circuit generates an offset address and a base address from a mask value and the current address. A modulus calculation via a plurality of adders, and selectors is performed to calculate the next address of the circular buffer to access. A sign selector associated with an inverter and the separator circuit sets a wrap around flag depending on whether a wrap around the circular buffer has occurred during the modulus calculation of the next address to access.
