Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

Abstract: Some embodiments include an integrated structure having vertically-stacked conductive levels alternating with dielectric levels. A layer over the conductive levels includes silicon, nitrogen, and one or more of carbon, oxygen, boron and phosphorus. In some embodiments the vertically-stacked conductive levels are wordline levels within a NAND memory array. Some embodiments include an integrated structure having vertically-stacked conductive levels alternating with dielectric levels. Vertically-stacked NAND memory cells are along the conductive levels within a memory array region. A staircase region is proximate the memory array region. The staircase region has electrical contacts in one-to-one correspondence with the conductive levels. A layer is over the memory array region and over the staircase region. The layer includes silicon, nitrogen, and one or more of carbon, oxygen, boron and phosphorus.

Abstract: A bracket for mounting a headrail of a venetian blind to a support surface such as a wall or ceiling. More specifically, a bracket comprising a platemeans having front and rear legs projecting downwardly and outwardly therefrom, and each of said legs including arresting means and said legs being resilient to assume a relatively tight fit of said headrail against said platemeans.

Abstract: A flexible extender adapted to being worn on the foot is disclosed. The foot extender according to the invention extends forwardly of the wearer for substantially its entire length. In accordance with the preferred embodiment, the foot extender comprises an elongated flexible base portion, a platform portion adapted to receive a shoe, and heel and toe straps to secure the extender to the foot of the wearer. The foot extender provides magnification of the foot's movement and power and is utilizable for creative encounters between the wearers, for dance or exercise, as an educational implement and as a creative plaything, to name a few.
