    摘要: A stepwise adjustable square for use in carpentry, including: a stock; and a blade rotatable relative to the stock around an axis of rotation between a first extreme position at zero degrees, where the blade is parallel to the stock and partly provided in a space of the stock, and a second extreme position at about 270 degrees, where the blade is substantially perpendicular to the stock.

    摘要: Certain aspects pertain to Fourier ptychographic tomographic systems and methods for acquiring a plurality of uniquely illuminated intensity measurements based on light passing through a thick sample from plane wave illumination at different angles and for constructing three-dimensional tomographic data of the thick sample by iteratively determining three-dimensional tomographic data in the Fourier domain that is self-consistent with the uniquely illuminated intensity measurements.

    摘要: This device is designed to replace and improve upon traditional framing lumber commonly used in home and commercial construction projects. The main problem that is addressed in this proposed improvement is the time that it takes to measure and mark lumber to be cut to specific lengths for the purpose of construction. This device serves to address this problem by pre-marking the lumber with conventional dimensional measurements (inches, centimeters, etc) that can be easily seen and used by the craftsman when cutting the lumber to the desired length.
