A multi-functional activity management system for elderly utilizes prior art walking sticks to manage big data related to activity of elderly persons. In addition, new improvements have been made upon prior art walking sticks. By incorporating umbrella function into the walking stick, the stem portion becomes narrower and shorter, thereby making it easy to be inserted into the thin walking stick. New functions have been developed from the prior art walking sticks for better use by the elderly persons.

A multi-source energy harvesting system, method and device are disclosed. The system, method and device incorporate multiple energy harvesting technologies to charge personal electronic devices.

A CANDYSHADE, sunshade is described as the combination of elements that may include; a sunshade frame component, an adjustable flexible arm with at least one quick connector in one of the ends, and a plurality of support members for fastening, attach or hold the sunshade to or in to an object. wherein the sunshade member is connectable to the first end of the support arm, and the support member is connected or connectable to the second end of the support arm.

The removable sunshade component may comprise a frame configuring a quick connector, i.e. a male screw. to be able to attach and detach from said flexible arm. Said frame may be foldable, including one or more folding axis, or may be configured to flex fold, or may be one piece rigid, further more may comprise a material to protect from direct sun heat, light, UVA, UVB, sun rays or other rays or light reflections that may cause inconvenience, harm or damage to the skin, hair, eyes, plants, pets, equipment and electronics and may comprise a clamp, or other system to keep the sunshade component all together, The arm may be flexible but strong and steady to support the sunshade component weight in multiple positions and withstand adverse outdoor and wind conditions, included but no limited to gusted winds, and must have at least one quick connector in one end, e.g. a female tread, and configured to attach permanently or temporally to a support member in the second end, to be able to attach the sunshade to another object such as a furniture or a pole or deck.

A CANDYSHADE may be light weight, stylish, easy to assemble, disassembly, install, storage and carry.
