20090263146	TONER LEVEL SENSING - A method and system to sense an amount of material such as toner in a container held in a horizontal position within a machine, such as a printing machine. A level sensor senses an amount of material within a dispensing unit which causes the level sensor to issue a signal. The dispensing unit is external to the container. The container holding the material is rotated, and a rotation direction reversed to a direction normally used to dispense the material. The reverse rotation direction moves the material to a closed end of the container. The container is then moved in a forward direction following the rotation of the container in the reverse direction. The forward rotation moves the material to the open end of the container, and the material further moves into the dispensing unit. A signal is generated when a sufficient amount of material has been moved into the dispensing unit. A time period is determined which represents the time it took to move the material from the closed end of the material, until the signal indicating a sufficient amount of material exists in the dispensing unit. The amount of material in the container is estimated by use of the determined time period.	10-22-2009

A blind source separation algorithm augments the directional separation through statistical techniques. The noise signal and speech signal are then used to set process characteristics at a dual input noise spectral subtraction suppressor (DINS) to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify speech signal.	04-23-2009
