Abstract: A radiation shielding device to be worn in conjunction with a radiation standard apron includes a first shielded portion configured to cover the right axilla and the outer quadrants of the right breast of a user with shielding material, a second shielded portion configured to cover the left axilla and the outer quadrants of the left breast of a user with shielding material, a first arm sleeve coupled to the first shielded portion and configured to cover an underside portion of a right proximal arm of a user with shielding material, a second arm sleeve coupled to the second shielded portion and configured to cover an underside portion of a left proximal arm of a user with shielding material, and a plurality of lightweight material portions coupling the first shielded portion and the second shielded portion.

Abstract: A controlled environment agriculture system including multiple environmental grow zones through which plants and/or lighting or other equipment that influence environmental equipment are cycled during the growth phase of farm production. In one implementation, the system includes multiple grow zones through which plants are cycled during the growth phase of farm production. The system may include a first environmentally-controlled growing chamber, a second environmentally-controlled growing chamber, and one or more interfaces to allow a conveyance mechanism to transfer grow containers between the chambers. Each growth chamber may include environmental control systems, and associated sensors, for regulating at least one environmental condition, such as air temperature, airflow speed, relative air humidity, and ambient carbon dioxide gas content.

Abstract: Techniques for reducing reduce coding artifacts in video data are disclosed. In one aspect, a frame of video data is partitioned into pixel blocks, which are organized into slices. The pixel blocks of each slice are coded by a compression algorithm and an estimate of coding artifacts in the slice is made. For slices that are estimated to possess coding artifacts, the method revises coding parameters applied to pixel blocks in the slice and recodes the slice. The method substitutes recoded slices for originally-coded slices in frame, working in a priority order from a slice with the highest estimated likelihood of coding artifacts down to slices with lower estimated likelihoods of coding artifacts, measuring changes in the frame's coding size as it goes.

Abstract: A coupling mechanism for removably coupling a storage cart to a surface maintenance machine includes a cart-side connector connectable to the storage cart and a machine-side connector connectable to the surface maintenance machine. The coupling mechanism includes a connecting rod engageable with the machine-side connector. The coupling mechanism includes a bracket assembly positioned between the cart-side connector and the machine-side connector. The bracket assembly can receive the connecting rod to engage therewith to facilitate a first relative movement between the connecting rod and a portion of the bracket assembly in a direction perpendicular to a floor surface on which the surface maintenance machine is traveling, and a pivoting of the bracket assembly about a pivot axis passing through the connecting rod.
