20100036510 | ELECTRONIC MOTOR CONTROLLER - A control system for any type of electric motor that automatically learns the characteristics of the motor and computes a motor model for the motor. The control system uses the computed motor model to produce a closed-loop control design that achieves a particular resolution. The control system also uses the motor model to automatically construct efficient motion profiles for a variety of motion commands. The control system may also include an encoder interface device that provides highly accurate motor position information. | 2010-02-11 |
20100036511 | APPARATUS AND METHOD FOR WIRELESS ACCESS AND CONTROL OF PROCESS CONTROL INSTRUMENTS - A method includes moving a wireless device into communication range of a process control instrument in an industrial process system. The method also includes presenting to a user, at the wireless device, a graphical user interface associated with the process control instrument. The method further includes receiving from the user one or more configuration settings associated with the process control instrument. In addition, the method includes transmitting information identifying the one or more configuration settings to the process control instrument in order to reconfigure the process control instrument. The method could optionally include presenting to the user, at the wireless device, a second graphical user interface when the wireless device is used to perform a function unrelated to interacting with the process control instrument. Here, the graphical user interface associated with the process control instrument could be presented in response to the wireless device detecting the process control instrument. | 2010-02-11 |
20100036512 | METHOD AND SYSTEM TO SELECT DEVICES OF A WIRELESS NETWORK, PARTICULARLY A NETWORK OF WIRELESS LIGHTING DEVICES - The invention relates to the selection of devices of a wireless network, particularly wireless home control networks, for example lighting control networks in buildings. It is an object of the invention to provide an improved method and System to select devices of a wireless network, particularly a network of wireless lighting devices. According to the invention, for selecting a certain device in the wireless network a broadcast message is sent out by a wireless remote device (S | 2010-02-11 |
20100036513 | AUDIO MIXING DEVICE AND METHOD - An audio mixing device and method are provided. The audio mixing device includes an analog to digital converter (ADC), a converting module, a mixing module, and a down-sample filter. The ADC is adapted to receive an analog signal, and convert the analog signal into a first digital signal. The converting module receives the second digital signal, and adjusts a data rate of the second digital signal according to a data rate of the first digital signal to generate a third digital signal. The mixing module mixes the first digital signal and the third digital signal to output a mixed signal. The down-sample filters down-samples the mixed to output a down-sampled signal. | 2010-02-11 |
