Abstract: The present invention relates to an apparatus and a method for accessing a cache memory. The cache memory comprises a level-one memory and a level-two memory. The apparatus for accessing the cache memory according to the present invention comprises a register unit and a control unit. The control unit receives a first read command and a reject datum of the level-one memory and stores the reject datum of the level-one memory to the register unit. Then the control unit reads and stores a stored datum of the level-two memory to the level-one memory according to the first read command.

Abstract: A latch assembly for a staple gun has a front cover, a locking element, a pushing element and a staple driver. The front cover has a connecting bolt. The locking element is mounted on the front cover and has two cams, a torsion spring and a locking block. The cams and the torsion spring are mounted around the connecting bolt. The pushing element is mounted in the front cover and has a pushing lever and a pressing pin. The pushing lever abuts the cams. The pressing pin extends out of the front cover. The staple driver is mounted in the front cover and has a locking hole, a through hole and an elastic panel. The locking hole is formed through the staple driver and engages the locking block. The latch assembly can hold a handle of the staple gun conveniently and safely when the staple gun is not being used.

Abstract: A channel estimation device for orthogonal frequency division multiplexing system and related method. The transmitting end transmits error detection signal of subcarrier, and the channel estimation is decided by whether the received signal at the receiving end is correct. Furthermore, in order to reduce the calculation complexity of the channel estimation, least square estimation is performed first, then MMSE estimation is performed to obtain more precise channel estimation, and singular value decomposition is utilized to reduce the calculation complexity of MMSE. The above-mentioned channel estimation method can obtain a better system efficiency in fast time variant channel.

Abstract: A pipe trap comprising a body, a disc filter, a pipe and a plurality of mesh filter suitable for filtering gases is provided. The pipe trap body has a gas inlet and a gas outlet. The disc filter and the mesh filters are enclosed inside the pipe trap body. One end of the pipe connects with the disc filter and the other end of the pipe connects with the gas outlet. The mesh filters are enclosed inside the pipe. Using a multi-stage filtering method, liquid matter separates out first and then gaseous particles are filtered according to the particle size so that the pipe trap has a high filtering efficiency.

Abstract: A staple gun with a latch assembly has a housing, a handle, a pivot pin, a spring, a staple driver and a staple magazine. The housing has two half-casings and a handle opening. The half-casings are symmetrical and connected to each other, and each half-casing has a latch tab. The latch tab is formed on and protrudes in from the half-casing. The handle is connected pivotally to the housing through the handle opening and has an inner end and a latch clip. The inner end extends into the housing between the half-casings and has two sides and two mounting slots formed respectively in the sides of the inner end and aligning with each other. The latch clip is mounted in and protrudes through the mounting slots to selectively engage the latch tabs and hold the handle in place.

Abstract: A stapling apparatus with a safety device for a stapler prevents staples from popping out of the stapler when a user wants to remove jammed or lodged staples. The stapling apparatus is pivotally attached to a stapler and has a housing with a front, a sliding front cover slidably mounted on the front of the housing so lodged staples can be conveniently removes and a safety device. The safety device includes a positive stop formed on the housing and a stop lip formed on the sliding front cover corresponding to the positive stop. When the user pushes the sliding front cover upward to remover lodged staples, the stop lip abuts the positive stop to limit movement of the sliding front cover. Therefore, the staples can be seen but are still held in the housing by the sliding front cover.
