Point-of-use water purification system with a cascade ion exchange option

A modular water treatment and purification system, suitable for home use, is connected to a water supply and contains a closed fluid treatment circuit extending to a water outlet. The closed fluid circuit flows through a plurality of replaceable water treatment modules each having a specific water treatment function, such as the removal of a particular material from the water by the use of filtration, carbon adsorption, ion exchange or the addition of a chemical to balance the desired water conditions. Preferably the circuit also includes traversing a radiation device, for example an ultra violet light, for the purpose of sanitizing the water.

Wireless stereo headset

Disclosed is a wireless stereo headset. The wireless stereo headset includes a first headset including a speaker unit and a Bluetooth® enabled module, for converting sound signals received from a device, transmitting the sound signals into sounds and outputting the sounds, and a second headset including a speaker unit and a Bluetooth® enabled module, for selectively receiving a portion of the sound signals which are converted into sounds and outputting the sounds, thereby accomplishing mono sound by using the first headset according to a user's request or achieving stereo sound by using the first and second headsets. The wireless stereo headset can perform voice communication by using only the first headset, while accomplishing stereo sounds by using both the first and second headsets, thereby using the wireless stereo headset to enjoy an improved sound quality.
