Abstract: A solute-dispensing closure is configured to mount on a filler neck of a container. Solute-dispensing closure can be operated by a user to discharge solute into solvent stored in a solvent reservoir provided in the container.

Abstract: A single use unit dosage dispensing closure includes a shell attached to a container, an axial movable cap attached to the shell, a dust cover preventing premature actuation of the cap, and a sealing member coupled to the cap. The shell has an inner guide in communication with the container and the cap is moveable along the guide. The cap has a chamber adapted to dispense material into the container. The chamber is sealed with the sealing member extending across a lower open end thereof, wherein axial movement of the cap along the inner guide member will open the chamber and dispense the contents of the chamber into the container. The axial movable cap is formed from a material with a higher oxygen and moisture barrier property than the material forming the shell.

Abstract: Low-cost intelligent control and communication devices are arranged to communicate with one another over one or more shared physical media, such as a powerline or a radio frequency band. No network controller is needed, because any device can act as a master, slave, or repeater. Adding more devices makes the system more robust, by virtue of a simple protocol for communication retransmissions and retries.

Abstract: A self-contained module including finger depressible keys, said module being mountable on, and useable with, a wireless keyboard for a computer. The module includes a pre-programmed microcontroller for controlling basic functions of the TV and an associated VCR via an IR LED on the keyboard.
