Abstract: A technique for writing data to pages in a QLC block of a QLC NAND flash memory device, where the device comprises a plurality of SLC pages organized in SLC blocks and a plurality of QLC pages organized in QLC blocks. The technique comprises storing received data in SLC pages, dividing equally a QLC block in a predefined number of sub-blocks according to a corresponding QLC page health status of the pages of the QLC block. Upon determining that SLC pages are to be copied from SLC pages to QLC pages, copying device-internal the respective SLC pages to the sub-blocks of the QLC block using device-internal cache registers, where the copying is based on an error-count aware scheme.

Abstract: A floor cleaning machine has a housing and a movable hood that covers over vacuum and liquid hoses of the machine that are visible in prior art floor cleaning machines. The vacuum and liquid hoses are each pivotally connected to a wall of the machine housing and are also pivotally connected to a transparent dome provided on the hood. These connections reduce stresses on the hoses when the hood is moved and allow the dome to pivot relative to the hood. The floor cleaning machine also has a pair of slit orifices that eject fan spray patterns of cleaning liquid that are non-coplanar and do not intersect each other. Furthermore, the floor cleaning machine has an oscillating brush assembly that includes a brush that is replaceable without using tools. The brush height can be adjusted via an adjustment member provided on the oscillating portion of the assembly.

Abstract: A kiosk for leasing carpet cleaning machines to customers comprises a storage unit and an electronic input device. The storage unit is configured to house a carpet cleaning device and comprises a locking portion and an electronically controlled lock. The electronically controlled lock is able to, alternatively, lock and unlock the locking portion. The storage unit is configured such that the carpet cleaning machine can be secured thereto by electronically locking the locking portion, and such that the carpet cleaning machine can be removed from or returned to the storage unit when the locking portion is unlocked. The electronic input device is adapted and configured to obtain a code key from a customer and to cause the electronically controlled lock to unlock the locking portion following the receipt of the code key without any remote communication with any other non-customer device external to the kiosk.

Abstract: A self-service kiosk enables customers to conduct rental transactions for carpet cleaning machines without the need of assistance from store personnel. The kiosk comprises a housing having several stalls or bays that hold and display carpet cleaning machines and carpet cleaning accessories for rental. The kiosk controls whether such carpet cleaning machines and carpet cleaning accessories can be removed from or returned to the kiosk. The kiosk also optionally includes a control panel for conducting a rental transaction. The self-service kiosk may also include automatic dispensing of cleaning products purchased by the customer at the kiosk. Still further, the self-serve kiosk may include shelving for holding cleaning products that can be purchased separately at a checkout counter.

Abstract: A method for generating and coding graphic images for transmission to hand-held or mobile devices uses an object-component technique wherein images are composed from a limited set of component types, particularly points and polygons. Images are encoded as a list of objects to be drawn, with each object specified by a command word (FIG. 3) followed by one or more coordinate words (FIG. 4) locating that object in a fixed coordinate image field. The command word indicates the object outline colour (c), the type of object (CC), and whether it is selectable (s) by a user for interactive applications. Parameter bits (p) in the command word indicate point radii or the number of polygon vertices. With a particular type (CC) setting, text strings may be included in the image.
