Abstract: A data padding device includes an internal memory, a direct memory access (DMA) circuit and a data processing circuit. The DMA circuit performs, according to a first padding control signal, data padding in a first direction on raw data during a process of reading the raw data from an external memory to generate first-direction padding data, and stores the first-direction padding data to the internal memory, wherein the first-direction padding data includes the raw data and first padding data originated from the raw data. The data processing circuit performs, according to a second padding control signal, data padding in a second direction on the first-direction padding data during a process of reading the first-direction padding data from the internal memory to generate second-direction padding data, wherein the second-direction padding data includes the first-direction padding data and second padding data originated from the first-direction padding data.

Abstract: An adjustable socket has a body, a connecting segment and an adjusting segment. The body has a proximal end, a distal end, a mounting hole, at least one adjusting recess and a through hole. The mounting hole is formed through the body. The at least adjusting recess is formed on the body. The connecting segment is mounted on the proximal end of the body. The adjusting segment is mounted on the distal end of the body and has a stationary clamp, an operating element and an adjusting clamp. The stationary clamp is formed on and protrudes from the body and has a guiding hole and two clamping faces. The operating element is rotatably mounted in the mounting hole and has a mounting rod and a worm wheel. The adjusting clamp is connected to and engages the operating element, faces the stationary clamp and has an engaging protrusion, multiple engaging teeth and two clamping faces.
