Abstract:
Systems and methods to detect and warn proximate entities of interest are described herein. An example signal generation system for a vehicle capable of different modes of movement includes a detector to determine at least one property of vehicle movement and an output representative of that at least one property and a selectively variable signal generator includes an input to receive the at least one output representative of the at least one property of vehicle movement and, responsively, generates a selected signal based on the received output. In some examples, a detector on a pedestrian detects the selected signal from the signal generator and, responsively, provides an output indicative of a vehicle in proximity to the pedestrian. In some examples, a trajectory vector is generated for at least two entities of interest based on at least one characteristic of movement of each entity. Each entity's trajectory vector is expanded and each entity's expanded trajectory vector is analyzed for overlap with the other entity's expanded trajectory vector to assess the possibility of a collision between them.
Abstract:
A watering device (40) comprising a receptacle (42) and a sponge wick (44). The receptacle (42) comprises a reservoir (46) and a probe (52). The probe (52) projects from the reservoir (46) and is adapted to extend into potting mix in a plant pot. The probe (52) is also adapted to hook on to the rim of the plant pot in order to support the device (40) thereon. The wick (44) is adapted to extend from the reservoir (46) within or along the probe (52) and into the potting mix in the plant pot. The wick (44) comprises non-woven Polyvinyl Alcohol fibres which are bound by a Polyvinyl Alcohol foam resin.
Abstract:
A wringing mechanism for buckets and the like containers, comprising a guide structure to be located at the upper portion of said bucket, said guide structure having associated therewith respective fixed and movable elements (6, 8), the movable element (8) being movable along a pathway defined by slots (3) provided in said guide structure, and a pedal (10), to be worked by the foot of an operator, in the form of a toggle linkage (11, 12) allowing for selective and continuous movement of the movable element (8) relative to fixed element (6) to cause ejection of excess water from a mop head drawn between the elements (6, 8).
