Abstract: This invention relates to a microcomputer and method for selecting foodstuffs from a foodstuff database, nutrients from a nutrient database, minerals from a mineral database, vitamins from a vitamin database and physical activities from a physical activity database, maintaining a record of the foodstuffs, nutrients, minerals and vitamins eaten and the physical activities exercised, and by computational means to analyze the selected and recorded foodstuff, nutrient, mineral and vitamin nutritional data along with the selected and recorded physical activities exercised to compare the user's daily dietary and physical activities to the user's RDA (recommended dietary allowance).

Abstract: The sheath for endoscope includes a tubular sleeve portion and a lens cover portion at one end of the tubular sleeve portion. The lens cover portion is of a predetermined thickness that minimizes light reflection onto the field of view of the endoscope. The sheath thus provides optimum visual acuity when used with the endoscope. The lens cover portion can include an anti-fogging ingredient to minimize condensation or congregation of fluids during examination. In several embodiments of the invention the sheath is rigid and in other embodiments of the invention the sheath is flexible. In any of the embodiments the lens cover portion can be joined to the inside, outside or end of the tubular sleeve. The lens cover portion can be formed with a cap section that is oriented at a selected predetermined angle with respect to a central axis. The sheath can have one or more reduced diameter sections to prevent relative slippage between the sleeve and the barrel of the endoscope.

Abstract: This invention relates to a microcomputer and method for selecting foodstuffs and maintaining a record of the nutritional values of foodstuffs eaten. The apparatus has a memory for receiving and retaining a data base of information regarding foodstuffs, accessing keys for accessing from the memory foodstuff identifying information regarding a selected class of foodstuffs from among those in the data base, a display for displaying a plurality of lines of information for a correponding plurality of foodstuffs accessed from the memory, selection keys for selecting from the display of a plurality of lines of information that foodstuff identifying and nutritional value information which relates to a specific foodstuff, and a register for registering the information selected from the display regarding a specific foodstuff and for accumulating over an interval of time the information regarding additional selected foodstuffs.
