Abstract: The present invention relates to a process for improving the solubility or dissolution behaviour of components in an aqueous solution. The dissolution properties of a slowly/badly dissolving component can be positively affected by generating mixed particles of this component with another component which has a negative dissolution enthalpy. By preparing and adding such mixed particles solubility is improved without changing the chemical composition.

Abstract: An interactive microprocessor based wireless communication device includes sound and data transceivers, signal detection and coupling devices, signal conversion device, voice recording, playback and storage device, voice activated device, display device, touch screen or similar device, sensors, frequency generation device, sound detection and reproduction devices and power source to concurrently perform generalized two way wireless communications, command, control and sensing functions utilizing radio and infra-red frequency communication links. A microprocessor receives signals from the touch screen and generates a digital data, command/or control signal for transmission to external devices such as home appliances and remote sensors. The microprocessor also responds to voice signal commands received via microphone and a voice processor. The microprocessor uses this signal to generate data, command/or control signals for transmission to external devices such as telephone, paging and intercom systems.
