A hypertext navigation system that is controllable by spoken words have hypertext documents to which specific dictionaries and probability models for assisting in an acoustic voice recognition of hyper-links of this hypertext document are allocated. Further, CMOS Image Sensors, including 1T Passive Pixels, or 1T Avalanche Photo-Diode Pixels, in which all pass transistors in the matrix are turned ON simultaneously thereby allowing the photo-current produced by each photo-diode in each pixel to flow towards the periphery where suitable circuitry will handle the photo-current for electrical power generation andor storage. The first sections of the capacitive elements have the same or substantially the same lengths, shapes, andor capacitance values. A second camera is positioned on the rear side of the vehicle spaced a horizontal distance from the first camera. The spray equipment may utilize inert gases that further contribute to improved characteristics in the treated food.
