Patent MX-9704437-A (MX)
Title: Sub-pixel dataform reader.
Inventor: WANG YNJIUN P
IPC: G06K9/50
Filed: 1997-06-12
Abstract: Sub-pixel processing of image data representing a dataform, such as a 2D bar code, enables reading of dataforms including more data/smaller elements, without costly increases in sensor and memory capacity. Whole pixel processing is employed for pixel-per-element resolutions of two or better. Sub-pixel cell edge transition location in image data is enhanced by use of a dynamically implemented noise margin applied with bands of gray scale values (150, 152) designated within the enveloppe of applicable gray scale maximum (119) and minimum (120) values. Sub-pixel cell edge transition location employs selection of transition segments (121-124), subject to the noise margin, and determination of a dynamic threshold (158) for each relevant transition segment (122). The intersection of the threshold (158) and the transition segment (122) is then indicative of the location of the cell edge transition along a sampling line crossing the dataform. The process is repeated for successive cell edges along image data sampling lines crossing successive rows of dataform elements. Run length data representing cell edge transition locations is constructed and usable for dataform decoding.

Title: Converting solar heat and radiation into mechanical motion - by utilising the forces generated by expansion and contraction
IPC: F03G7/06
Filed: 1978-12-07
Abstract: Differences in temp. and the great quantities of heat occurring in nature and originating in the sun are to be exploited by means of the natural and mechanical characteristics of metals. The stretch, shrinkage and the stress in the Hook elastic zone, together with the natural extension and contraction caused by temp. differences, are to be used for the generation and storage of mechanical and electrical energy. The extension and contaction of metals can be transformed directly into mechanical and electrical energy. It is proposed to install very long bars of steel side by side in solar heat collectors in which they move on rollers as they expand and contract. The bars will heat up very rapidly and will be cooled by sea water. The power of the reciprocating motion is converted into rotary power by driving wheels on a shaft coupled to a gear box.
