Abstract:
The present invention discloses a transmit-receive (TR) front end. The TR front end includes a low-noise amplifier (LNA); a power amplifier (PA); a transformer, coupled to the PA, for increasing a voltage swing and a power transmission of the PA; and a TR switch, coupled between the transformer and the LNA. The LNA is single ended and there is no transformer between the LNA and the TR switch.
Abstract:
A semiconductor package is provided, which includes a substrate unit having conductive pads and ESD protection pads formed on a bottom surface thereof; an encapsulant covering a top surface of the substrate unit; and a metal layer disposed on a top surface of the encapsulant and having connecting extensions formed on side surfaces of the substrate unit and the encapsulant for electrically connecting the ESD protection pads, wherein portions of the side surfaces of the substrate unit corresponding in position to the conductive pads are exposed from the metal layer so as to ensure that solder bumps subsequently formed to connect the conductive pads of the semiconductor package to a circuit board are not in contact with the metal layer, thereby effectively avoiding the risk of short circuits.
Abstract:
A memory apparatus and a method of evenly using the blocks of a flash memory are provided. The memory apparatus comprises a flash memory and a controller. The flash memory comprises a data region with a plurality of data blocks and a spare region with a plurality of spare blocks. The controller is configured to receive data corresponding to the first data block, select a spare block, program data into the spare block when the erase count corresponding to the spare block is less than the predetermined value or to select a second data block and program data stored in the second data block into the spare block when the erased count corresponding to the spare block reaches the predetermined value. As a result, the blocks of the flash memory are used evenly.
Abstract:
An optical diffusion device applied in a backlight module includes a plate. Multiple light sources are disposed on one side of the plate. Multiple optical microstructures provided with a longer axis and a shorter axis are disposed on the plate. The longer axis of each optical microstructure is approximately arranged in parallel with a direction extending from the light source, or, in other words, the shorter axis is arranged approximately crossing the direction extending from the light source. A diffusion effect is provided to each light source through the shorter axis of the optical microstructure to increase optical radiant energy among the light sources and to eliminate the dim and dark regions among the light sources for increasing general luminance of the backlight module.

A corneal cover or corneal implant to be placed within or onto the surface of the cornea is made of bony fish scales and a contact lens is made of bony fish scales.
Abstract:
An approximation method for SNR soft information for a transmitter of a communications system includes obtaining a conditional probability density function (PDF) corresponding to a response message of a transmitted packet, obtaining a PDF of a probability distribution model, and a mean and a variance of the PDF, by approximating the conditional PDF corresponding to the response message with the probability distribution model, and calculating a second mean and a second variance of a second PDF approximated to a conditional PDF of SNR corresponding to the transmitted packet according to the mean and the variance of the PDF, and a first mean and a first variance of a first PDF approximated to a conditional PDF of SNR corresponding to another transmitted packet immediately preceding the transmitted packet.
Abstract:
The invention comprises a memory module capable of wear-leveling. In one embodiment, the memory module comprises a flash memory and a controller. The flash memory comprises a plurality of management units, wherein each of the management units comprises a plurality of blocks. The controller receives new data with a logical address managed by a first management unit selected from the management units, pops a first spare block from a spare area of the first management unit, determines whether an erase count of the first spare block is greater than a first threshold value, searches a second management unit selected from the management units for a replacing block with an erase count lower than a second threshold value when the erase count of the first spare block is greater than the first threshold value, and directs the first management unit and the second management unit to exchange the first spare block with the replacing block.
