The holes by way of every card might be patterned (or an insert inside each card formed) so that the control code outlined by the card is dependent upon the orientation of the card relative to the magnetically actuated change array. In different embodiments, the programming card is designed to selectively actuate a mechanical or optical change (rather than a magnetic swap), and commands are entered to the processor by exposing arrays of mechanically or optically actuatable switches to such a programming card. Thus, if the card is sq.-shaped and sized for insertion towards a sq.-shaped card reading location (e.g., a recessed window) of a management meeting wall, the card can define eight totally different management codes depending on which edge of the card faces a selected edge of the card studying location and which face of the card faces the wall. More typically, the card can have any polygonal shape (i.e., hexagonal or rectangular) and might be sized for insertion in opposition to a card reading location of corresponding (polygonal) shape.

When the card is positioned near the magnetic switches (ideally at a station outside the sealed walls of the control meeting), the presence or absence of a gap (or steel insert portion) close to each switch causes every transducer to assert a sign (e.g., a binary zero or one) to the microprocessor, to command the microprocessor to execute certainly one of a number of pre-programmed packages (and thus function in one in all several corresponding predefined modes). The working modes can even outline the size of time for a given cleaning cycle in order that cleansing time may be optimized for a given pool size. Examples of such predefined operating modes embrace cleansing patterns specially suited for cleansing rectangular-shaped or kidney-shaped ASP – America’s Swimming Pool Company of Central Texas pools, patterns for cleansing solely a portion of a pool similar to the underside surface, and cleansing procedures for cleaning several types of pool floor media (comparable to concrete or vinyl). Thus, the cleaner could be programmed to operate only so long as wanted to scrub a given dimension of Florida Plastering & Pool Remodeling.

FIG. 10 is a aspect elevational view of the cam-pushed shifting mechanism of FIG. 9, in a second place. FIG. 10A is a diagram of two cams that are on a shaft in an embodiment of the invention. FIG. 12 is a facet elevational view of the transmission gear portion of the shifting mechanism of FIG. 8, with the shifting mechanism able for reverse rotation of the corresponding wheel. FIG. 13A is a side cross-sectional view of a portion of a most popular substitute for the computerized energy switch of the FIG. Thirteen apparatus. FIG. 11 is a facet elevational view of the transmission gear portion of the shifting mechanism of FIG. 8, with the shifting mechanism able for ahead rotation of the corresponding wheel. FIG. Thirteen is a schematic diagram representing sensors employed in the FIG. 1 apparatus, and an interface circuit and processor for processing output signals produced by the sensors.

Such left and proper turbines would be selectively controllable by left and right management (“transmission”) assemblies. 27 and 28, roller brush 46 is replaced by two fixedly mounted straight brushes 46a. Certainly one of brushes 46a is mounted on the entrance of the apparatus (as shown in FIG. 27), and the opposite is mounted on the rear of the apparatus (as proven in FIG. 28). In the choice embodiment shown in FIG. 25, housing member 18 is designed so that roller brush 46 might be rotatably mounted to it, or straight brush 46a will be fixedly mounted to it. Brush forty six rotates passively (towards brush bearings 38, shown in FIG. 6) when monitor treads 20 and 22 translate the inventive apparatus along the submerged surface. Roller brush 46 (shown in FIGS. In the popular embodiment to be described with reference to FIGS. 1, 4, Fort Worth and 5, and extra clearly shown in FIG. 6) is rotatably mounted on physique 18 of the inventive apparatus, in a position contacting the submerged floor being cleaned.

All of the drive prepare parts shown in FIG. 8 are topic to exposure to the liquid environment by which the inventive apparatus operates. Input/output electronic circuit board 70 is electrically related to board 68, and mounted within assembled components 14a, Florida Coastal Contractors 14b, and 14c ready facing the window seventy three of portion 14b. Magnetically actuated switches (comparable to Hall impact transducers and circuitry for processing the electrical output thereof) for sensing patterns of holes (or magnetically permeable inserts) in magnetic programming cards to be described under, and one or more light-emitting diodes (e.g., LEDs 72 proven in FIG. 23 or single LED seventy two proven in FIG. 28) could be mounted on board 70. These elements will be mentioned under in higher detail. In contrast, the FIG. 7 parts (including the microprocessor and related management circuitry, and the transmission hardware to be described beneath) and the onboard sensors shown in FIGS. The drive train components need not be mounted in a sealed enclosure, and need not be otherwise isolated from the liquid (though they might be so remoted in different embodiments of the invention). 13, 18, and 21 (represented by blocks in FIG. 23), which collectively comprise control box assembly 14, are mounted in a sealed enclosure to isolate them from the surrounding liquid. Several of the inventive onboard sensors (for supplying standing information to the onboard microprocessor) are equally mounted in positions exposed to the encircling liquid atmosphere.
