Dietetic measurement apparatus
First Claim
1. A dietetic measurement apparatus characterized in that it comprises computer means comprising a central processing unit, request means including alphabetic keyboard for allowing selection of food items by character string of the name of the food item, input/output means connected to the central processor unit for sending data from the central processor unit to a display means and for receiving requests from the request means and for routing such requests to the central processor unit, weighing means for providing a weighing signal to the central processor unit corresponding to the mass of an item being weighed, memory means connected to the central processor unit for containing data corresponding to food items and their nutrient levels and including instruction means for the central processor unit to correlate the weighing signal with data for a food item or items requested from the request means and providing a determination of the mass and the nutrient levels thereof to the display means, said request means including a scroll up and scroll down request key to direct the central processor unit via the instruction means to proceed and retreat, respectively, from data relating to a current food item in the memory means to data relating to an adjacent food item.

Abstract
A dietetic measurement apparatus (10) having computer means (30) having a controlling instruction means to provide a determination of basic integers for a mass of a food item weighed on a weighing means (32). The weighing means (32) provides a weighing signal, in the form of a logical periodic signal, to a central processor unit (34) of the computer means (30), which measures the frequency of the weighing signal and correlates the mass of the food item and the quantities of the nutrients. The nutrients comprise carbohydrate, calcium, cholesterol, fat, fibre, iron, protein, sodium and calorific content. Also a number of command keys (22a) are provided and include a ZERO key and a BOWL key to aid in weighing procedures.

11. A dietetic measurement apparatus comprising:
- weighing means having a platter attached upon a load cell for providing a weighing signal corresponding to the mass of an object being weighed upon the platter;
computer means including memory means for containing data corresponding to food items including their unit masses and nutrient levels, a central processor unit connected to the memory means for executing requests and for receiving the weighing signal and storing same in the memory means, display means for displaying data output from the central processor unit, an alphanumeric keyboard for entering requests to the central processor unit, and input/output means for directing data between the central processor unit and the display means and the alphanumeric keyboard, respectively; and
request means including zeroing request means for directing the central processor unit to reset the weighing signal stored in the memory means in order to disregard the mass of a first container placed upon the platter, find request means for directing the central processor unit to search for data in the memory means and for selecting food items by a character string located within he name of the food item such that the exact food name need not be requested, and add request means for directing the central processor to accumulate masses and nutrients levels for objects subsequently weighed in the weighing means, request means including scroll request means to direct the central processor unit to search for either an alphabetically preceding or succeeding food item by name, the scroll request means having a scroll down key to locate the alphabetically preceding food item name and a scroll up key to locate the alphabetically succeeding food item name.
- weighing means having a platter attached upon a load cell for providing a weighing signal corresponding to the mass of an object being weighed upon the platter;
-
12. A dietetic measurement apparatus comprising;
- display means;
computer means including a central processor unit, request means including alphabetic keyboard for allowing selection of food item names by character string less than the number of characters of the name of the food item and for directing the central processor to scroll forward or backward alphabetically for food item names respectively succeeding or preceding the selected food item while displaying on said display means, input/output means connected to the computer means for sending data from the central processor unit to said display means and for receiving request from the request means and for routing such request to the central processor unit, weighing means for providing a weighing signal to the central processor unit corresponding to the mass of an item being weighed, memory means connected to the computer means for containing data corresponding to food items and their nutrient levels and including instruction means for the central processor unit to correlate the weighing signal with data for a food item or items requested from the request means and providing a determination of the mass thereof of the display means.
