Abstract: A clothes washing machine system including a method of detecting a load unbalance. The washing machine system includes a cabinet having a drum rotatably mounted therein. A motor is coupled to the drum for rotating the drum within the cabinet. A memory device is accessible by a processor, such as a digital signal processor (DSP). The memory contains program code for implementing a method that includes determining the motor torque ripple, determining the motor speed, and determining the load unbalance mass based on the motor torque and speed.

Abstract: When an engine is operated, a power dividing mechanism divides power of the engine to output the power to a motor for running operation and a motor for a cargo handling operation, respectively. Each of loads is driven via a rotational shaft of a corresponding one of the motors. By operating the engine and supplying the motors with electric power from a battery to operate the motors, each of the loads can also be driven by the sum of power of the engine and power of a corresponding one of the motors. When surplus power is generated in the power of the engine, each of the motors is operated as an electric power generating unit by the surplus power. As a result, the battery is charged.

Abstract: A method for receiving consumer-initiated business service look-up requests entered into a GPS unit, along with the corresponding geographic location the request was entered. These requests are received at a Central Processing Station whereupon the data is analyzed to identify concentrations of similar requests within a geographic region.

Abstract: An exposure apparatus for exposing a substrate coated with a photosensitive material to radiant energy comprises a first controller and a second controller. The first controller is configured to control a process of exposing the substrate. The second controller is configured to generate a control signal corresponding to a time at which the substrate is exposed under a control by the first controller, and to transmit the control signal to a developing apparatus.
