Abstract: A synthesis method of cathode material for lithium battery is provided. The method includes dissolving lithium, nickel and cobalt acetate in a solution, adding ammonium dihydrogen phosphate to the solution, adding acid to the solution, heating the solution to a first temperature for a first period of time to form a solid mixer material, and sintering the solid mixer material at a second temperature for a second period of time.

Abstract: The robotic system for harvesting, and performing pre- and post-harvesting tasks of date palm trees includes three main parts: a truck platform, a scissor lift, and a multi-task system. The truck platform provides mobility for the whole system, while the scissor lift raises the multi-task system to the top of the palm tree. The multi-task system is fixed on top of the scissor lift and includes a large basin that catches fruits during harvesting. A circular track is fixed within the basin and includes a 2-degree-of-freedom (DOF) slider base mounted thereon. On top of the 2-DOF slider base is a robotic arm fitted with the proper tool (harvesting tool, maintenance tool or bagging system) for the task to be performed. The circular track has pivoting sections, and the basin has a flexible portion in the rear of the truck platform to allow the system to surround the palm tree.

Abstract: A bib extends from the person's neck to the eating surface, thus eliminating foods of liquids from falling onto flooring, furniture and clothing while eating or engaging in other messy activities. The bib includes a bib body made of a liquid repellent material that can attach around a user's neck. Bib arms can extend from each side of the end of the bib body. The bib arms can be weighted to hold them on a table or other surface, where the bib body can extend from the wearer to the table, catching spills from the user that would otherwise end up on furniture, the floor or the user's lap.
