ABSTRACT:
An apparatus and method for displaying the weight or cost of an uncut selected segment of an item involves passing a position indicating member over the item lying on a support surface. The position indicating member carries one or more sensors which generate signals corresponding to succeeding cross sectional contours of the item as the member is traversed along the item from a reference position to a selected other position over this item, defining the selected segment of the item. At the same time, a motion detector arrangement preferably comprised of one or more microelectromechanical (MEMS) accelerometer devices generates signals corresponding to motion of the position indicator support member as it is moved along the item. These signals are processed in a signal processor to determine the volume of the uncut selected segment of the item lying between selected successive positions of the indication member. Each of these cumulative volume determinations are converted into numeric weight or price values based on the density factor for the particular type of item, whereby numeric weight and price values (based on weight) are displayed as the member is traversed along the item, thus enabling the operator to contemporaneously provide an on-looking consumer weight or price information before a particular segment is cut from the item. A visible light band is projected from the sensor bar onto a section of the item to clearly show the selected segment bounds corresponding to the numeric display to the onlooker.
