Abstract: A flexible photovoltaic (PV) cell having enhanced properties of mechanical impact absorption, includes: a semiconductor wafer that is freestanding and carrier-less; having a thickness, and having a first surface, and a having second surface that is opposite to that first surface; a set of non-transcending gaps within the semiconductor wafer. Each non-transcending gap penetrates from the first surface towards the second surface but reaches to a depth of between 80 to 99 percent of the thickness of the semiconductor wafer, and does not reach said second surface. Each non-transcending gap does not entirely penetrate through an entirety of the thickness of the semiconductor wafer. The semiconductor wafer maintains at least 1 percent of the thickness of the semiconductor wafer as an intact and non-penetrated thin layer of semiconductor wafer that remains intact and non-penetrated by the non-transcending gaps. The intact and non-penetrated thin layer of semiconductor wafer absorbs and dissipates mechanical forces.

Abstract: A method and a device for storing medical data from medical records and subsequently extracting knowledge and information are disclosed. Data is continuously stored in a database, while knowledge accumulated in an accompanying medical dictionary and an accompanying medical knowledge directed acyclic graph.

Abstract: A corporate disclosure and repository system includes one or more software programs which execute on one or more general purpose data processing systems. The software programs include components for gathering information in the form of free form text documents, reducing the information to a formatted database, analyzing the contents of the database and reorganizing the database in a format suitable for drawing inferences with respect to the contents thereof and synthesizing inferences based upon the contents of the reorganized database. The software programs may be used both intracompany, in preparing documents for deposit in the repository system, and intercompany, in reviewing documents already deposited in the repository system. The intercompany part may be further divided into parts useful to regulators and parts useful to the public.
