The holes via each card might be patterned (or an insert within every 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 alternative embodiments, the programming card is designed to selectively actuate a mechanical or optical switch (moderately than a magnetic change), 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-formed and sized for insertion against a square-formed card reading location (e.g., a recessed window) of a management assembly wall, the card can outline eight different control 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 generally, the card can have any polygonal shape (i.e., hexagonal or rectangular) and will be sized for insertion towards a card studying location of corresponding (polygonal) shape.
When the card is positioned close to the magnetic switches (preferably at a station exterior the sealed walls of the control assembly), the presence or absence of a hole (or steel insert portion) near each swap causes every transducer to assert a signal (e.g., a binary zero or one) How To Find pool builders Houston TX the microprocessor, to command the microprocessor to execute certainly one of several pre-programmed packages (and thus function in one among a number of corresponding predefined modes). The operating modes may define the length of time for a given cleansing cycle in order that cleansing time may be optimized for a given pool size. Examples of such predefined working modes include cleaning patterns specially suited for cleaning rectangular-formed or kidney-formed swimming swimming pools, patterns for cleaning only a portion of a 24 hour pool services California resembling the underside surface, and cleansing procedures for cleansing several types of Inground Pool Prices California surface media (akin to concrete or vinyl). Thus, the cleaner can be programmed to operate solely as long as wanted to wash a given dimension of pool.
FIG. 10 is a facet elevational view of the cam-driven shifting mechanism of FIG. 9, in a second position. FIG. 10A is a diagram of two cams which are on a shaft in an embodiment of the invention. FIG. 12 is a side 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 well-liked substitute for the automatic power switch of the FIG. Thirteen apparatus. FIG. 11 is a side elevational view of the transmission gear portion of the shifting mechanism of FIG. 8, with the shifting mechanism able for forward rotation of the corresponding wheel. FIG. 13 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 proper management (“transmission”) assemblies. 27 and 28, roller brush forty six is changed by two fixedly mounted straight brushes 46a. One among 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 shown in FIG. 28). In the alternative embodiment proven in FIG. 25, housing member 18 is designed so that roller brush forty six 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 along the submerged surface. Roller brush 46 (proven 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, ready contacting the submerged floor being cleaned.
All the drive practice parts proven in FIG. Eight are topic to exposure to the liquid environment wherein the inventive apparatus operates. Input/output electronic circuit board 70 is electrically linked to board 68, and mounted inside assembled components 14a, 14b, and 14c ready going through the window seventy three of portion 14b. Magnetically actuated switches (comparable to Hall effect 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 below, and one or more light-emitting diodes (e.g., LEDs 72 shown in FIG. 23 or single LED 72 proven in FIG. 28) will be mounted on board 70. These components will probably be mentioned beneath in better detail. In contrast, the FIG. 7 parts (together with the microprocessor and related management circuitry, and the transmission hardware to be described under) and the onboard sensors shown in FIGS. The drive practice elements need not be mounted in a sealed enclosure, and want not be in any other case isolated from the liquid (though they might be so remoted in alternative embodiments of the invention). 13, 18, and 21 (represented by blocks in FIG. 23), which collectively comprise control box meeting 14, Sitemap are mounted in a sealed enclosure to isolate them from the encompassing liquid. Several of the inventive onboard sensors (for supplying standing information to the onboard microprocessor) are similarly mounted in positions exposed to the encompassing liquid setting.
