Abstract: The present application provides a footwear for postoperative protection and rehabilitation. The protective footwear specifically structurally includes: a footwear body; an air bag system, provided at a position of the footwear body corresponding to a human metatarsal region; and a fixing frame, provided at the position of the footwear body corresponding to the human metatarsal region, wrapping a compressed air bag, and comprising a flat plate and two arc-shaped plates extending upward and inward from two sides of the flat plate; where, when a human foot is squeezed by gravity, air in a bottom air reservoir is squeezed into side-flap air reservoirs, such that the side-flap air reservoirs are inflated; and restricted by the fixing frame, the side-flap air reservoirs generate an inward pressure to the metatarsal region to reduce a tensile stress generated between metatarsals when the human foot moves.

Abstract: In one embodiment, there is provided a dynamic multi-source image reconstruction apparatus. The apparatus includes a first reconstruction stage, a second reconstruction stage, and a refinement stage. The first reconstruction stage is configured to receive an input data set including a group of data frames. Each data frame corresponds to a respective time step. Each data frame includes a number of projection data sets. Each projection data set corresponds to a respective source-detector pair of a stationary multi-source tomography system. The first reconstruction stage is further configured to reconstruct a first intermediate image based, at least in part, on the group of data frames. The second reconstruction stage is configured to receive a selected data frame and to reconstruct a second intermediate image with a constraint of the first intermediate image as prior. The refinement stage is configured to refine the second intermediate image to produce a three-dimensional output image.

Abstract: Systems and methods relating to analog-to-digital converters. A delay block receives an input signal at the same time as a coarse ADC (CADC) block. The CADC block produces a multi-bit output and this output is applied to a signal processing block. The delay block delays the input signal from being applied to the signal processing block until the output of the CADC block has been applied/configures the signal processing block. The signal processing block may be a signal shifter, the output of which is ultimately applied to a fine ADC (FADC) block. In an alternative, the signal processing block may be the FADC block. Regardless of the configuration, the output of the CADC is delayed until the output of the FADC block is available. The outputs of the CADC and the FADC blocks are then simultaneously applied to an encoder that produces the overall system output.
