Abstract: A portable beverage preparation device and system for making brews, mixes, and potions on demand by selectively introducing and mixing predetermined quantities of at least one stored, edible, beverage preparation confined in at least one sealed chamber into a portable beverage container containing a predetermined volume of a potable base liquid and having a dispenser means for introducing the at least one beverage preparation into the potable base liquid; wherein the drink container and the at least one sealed chamber are in close physical proximity to each other and separated by at least one thin membrane which, when inwardly perforated by the dispenser means, introduces the at least one beverage preparation into the base liquid. The system of the invention further provides a brewing element and a portable heating unit, the heater element of which fits into the beverage container for heating the liquid.

Abstract: A brewing element comprising an envelope for storing at least one comestible brewing ingredient therein; and an attachment means for removably attaching the element to a container, the element having formed therein a central inlet for admitting pressurized, heated water and a peripheral outlet for releasing a mixture of the at least one comestible brewing ingredient with the pressurized, heated water, wherein when the brewing element is incorporated into an operating beverage brewing system, the capsule releases the mixture multi-directionally through the peripheral outlet to provide a brewed beverage into the container.

Abstract: An autonomous robot, that is for example, suitable for operations such as vacuuming and surface cleaning includes a payload configured for vacuum cleaning, a drive system including a steering system, a navigation system, and a control system for integrating operations of the aforementioned systems.

Abstract: A self-contained foam dispensing device includes a casing, a mixing chamber, a port adapted to receive one or more containers including a plurality of chemicals in a plurality of compartments and a flow generator adapted to induce flow of chemicals from the compartments toward a mixing chamber, the flow generator being located between the mixing chamber and the port. When the one or more containers are in the port the one or more containers move with movement of the casing.

Abstract: A portable beverage preparation device comprising a drink container containing a predetermined volume of a potable base liquid, at least one beverage preparation of a predetermined quantity; at least one sealed compartment for confining the beverage preparation, and a dispenser means for dispersing the at least one beverage preparation into the base liquid within the drink container; wherein the drink container and the at least one sealed compartment are in close physical proximity to each other and separated by at least one thin membrane which, when inwardly perforated by the dispenser means, disperses the at least one beverage preparation into the base liquid to make a beverage ready to drink.

Abstract: Mesh deployment apparatus including a deployment rod having a handle at a proximal portion thereof and a roller portion at a distal portion thereof, the roller portion having a mesh-sheet attachment member for attaching a mesh-sheet thereto, wherein the roller portion is articulated with respect to the deployment rod by means of a joint, and a manipulating member coupled to the roller portion for moving the roller portion about the joint to a position wherein the roller portion is not collinear with the deployment rod.

Abstract: A method including removing feline exudates from litter, washing and drying the litter, wherein the litter is agitated during drying thereof. Feline exudate apparatus is also described that includes a vessel for containing therein litter, apparatus for washing the litter; and apparatus for drying the litter, wherein the litter is agitated during drying thereof.

Abstract: A chemical mixing device. The device includes a flow generator operative to provide at least two streams of chemicals and a mixing chamber, including at least two inlets adapted to receive the at least two streams of chemicals and an outlet through which a mixture of the streams of chemicals is ejected from the mixing device. The mixing chamber has an open state in which the chemicals are mixed and a closed state in which the volume of the mixing chamber is less than a fifth of the open state volume.
