The holes by way of every card will be patterned (or an insert within each card formed) so that the management code defined by the card depends upon the orientation of the card relative to the magnetically actuated swap array. In different embodiments, the programming card is designed to selectively actuate a mechanical or optical swap (slightly than a magnetic switch), 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 square-shaped and sized for insertion towards a square-formed card studying location (e.g., a recessed window) of a management assembly wall, the card can define eight completely different control codes depending on which edge of the card faces a selected edge of the card reading location and which face of the card faces the wall. More generally, the card can have any polygonal shape (i.e., hexagonal or rectangular) and will be sized for insertion in opposition to a card studying location of corresponding (polygonal) form.
When the card is positioned close to the magnetic switches (preferably at a station exterior the sealed walls of the management assembly), the presence or absence of a gap (or metallic insert portion) close to each swap causes every transducer to assert a signal (e.g., a binary zero or one) to the microprocessor, to command the microprocessor to execute one among a number of pre-programmed applications (and thus operate in one of a number of corresponding predefined modes). The working modes also can outline the size of time for a given cleaning cycle in order that cleansing time may be optimized for a given AZ Pool Service measurement. Examples of such predefined operating modes embody cleaning patterns specially fitted to cleaning rectangular-shaped or kidney-shaped ASP – America’s Swimming Pool Company of Central Texas swimming pools, patterns for cleaning solely a portion of a Aro Pool Builders Innovations Inc comparable to the underside surface, and cleansing procedures for cleaning various kinds of {AZ’s Best Pool Service & Repair|https://poolcontractorsquotes.com/directory/bahama-pools-of-southwest-florida-inc/ surface media (comparable to concrete or vinyl). Thus, the cleaner could be programmed to function solely so long as wanted to wash a given dimension of pool.
FIG. 10 is a side elevational view of the cam-driven shifting mechanism of FIG. 9, in a second place. FIG. 10A is a diagram of two cams which might be on a shaft in an embodiment of the invention. FIG. 12 is a aspect elevational view of the transmission gear portion of the shifting mechanism of FIG. 8, with the shifting mechanism in a position for reverse rotation of the corresponding wheel. FIG. 13A is a aspect cross-sectional view of a portion of a most popular substitute for the automatic power switch of the FIG. 13 apparatus. FIG. 11 is a aspect elevational view of the transmission gear portion of the shifting mechanism of FIG. 8, with the shifting mechanism ready for forward rotation of the corresponding wheel. FIG. Thirteen is a schematic diagram representing sensors employed within 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 control (“transmission”) assemblies. 27 and 28, roller brush forty six is replaced by two fixedly mounted straight brushes 46a. Certainly one of brushes 46a is mounted on the front of the apparatus (as proven in FIG. 27), and the opposite is mounted at the rear of the apparatus (as shown in FIG. 28). In the choice embodiment proven in FIG. 25, housing member 18 is designed so that roller brush 46 may be rotatably mounted to it, or straight brush 46a can be fixedly mounted to it. Brush 46 rotates passively (in opposition to brush bearings 38, shown in FIG. 6) when monitor treads 20 and 22 translate the inventive apparatus alongside the submerged surface. Roller brush forty six (shown in FIGS. In the popular embodiment to be described with reference to FIGS. 1, 4, and 5, and extra clearly proven in FIG. 6) is rotatably mounted on body 18 of the inventive apparatus, able contacting the submerged surface being cleaned.
All of the drive train components shown in FIG. Eight are topic to publicity to the liquid surroundings by which the inventive apparatus operates. Input/output electronic circuit board 70 is electrically connected to board 68, and mounted within assembled elements 14a, 14b, and 14c able dealing with the window seventy three of portion 14b. Magnetically actuated switches (equivalent to Hall effect transducers and circuitry for processing the electrical output thereof) for sensing patterns of holes (or magnetically permeable inserts) in magnetic programming playing cards to be described under, and a number of light-emitting diodes (e.g., LEDs 72 proven in FIG. 23 or single LED seventy two shown in FIG. 28) will be mounted on board 70. These components will probably be discussed below in higher detail. In distinction, the FIG. 7 components (together with the microprocessor and associated management circuitry, and the transmission hardware to be described beneath) and the onboard sensors proven in FIGS. The drive practice elements need not be mounted in a sealed enclosure, and want not be otherwise remoted 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 field assembly 14, are mounted in a sealed enclosure to isolate them from the encircling liquid. Several of the inventive onboard sensors (for supplying status information to the onboard microprocessor) are equally mounted in positions exposed to the surrounding liquid surroundings.
