International Classification:

A47B 83/02
A47C 7/62

US Classification:

297137, 2972173, 2972171

Abstract:

An interactive entertainer having a lower tray with a plurality of compressible legs supporting an upper tray. The lower tray is concave to permit rocking of the tray when placed on a flat surface. One or more supports coupled to the lower tray may be repositioned to inhibit rocking of the lower tray. The legs can fold into the lower tray following separation of the upper tray. The lower tray can then nest within the upper tray to provide compact storage. The upper tray can support a seat that is selectively rotatable or stationary based on a position of a seat lock. A plurality of interactive devices may be positioned on the upper tray. One or more sensors may be positioned relative to the seat to detect the orientation of the seat relative to the devices. The devices may be selectively enabled based on the seat orientation.

International Classification:

G05D 1/02
A47L 11/40

Abstract:

A robotic cleaning device and method of control thereof. The device and method enable multiple cleaning passes within an environment efficiently, cleaning the entire environment more than once, or cleaning the entire environment and then focusing on one or more particularly dirty areas to provide enhanced cleaning by making one or more passes over a dirty area in a dominant and a non-dominant direction. The robotic cleaning device may identify such areas in the course of its cleaning, or it may record such areas previously as being historically dirty and requiring additional attention. The device may vacuum; it may shampoo; it may polish; or it may perform other cleaning operations. Where the device is battery-powered, the device may check its state of charge before performing the enhanced cleaning, and may repeat the enhanced cleaning if the battery or batteries have sufficient charge.
