  • Publication number: 20090266623
    Abstract: A remote sensing controller having a detection area, wherein the remote sensing controller comprises: a plurality of electromagnetic wave generators, a sensor, a determining module and a controlling module. The plurality of electromagnetic wave generators are to generate an electromagnetic wave respectively, wherein at least one reflected electromagnetic wave is further generated according to the reflection of the plurality of electromagnetic waves from an object within the detection area, wherein the number of the reflected electromagnetic wave is related to a displacing condition of the object. The sensor is to sense the reflected electromagnetic wave to generate a sensing result. The determining module is to determine the displacing condition of the object according to the sensing result. And the controlling module is to generate a command corresponding to the displacing condition according to a relation table and further control at least one external electronic device according to the command.

  • Patent number: 6681271
    Abstract: A computer system for multi-type DRAM support includes a first slot for receiving a first type DRAM, a second slot for receiving a second type DRAM, a north bridge chip, and a control circuit. The first slot includes a plurality of first slot pins, and each of them corresponds to a first pin assignment. The second slot includes a plurality of second slot pins, and each of them corresponds to a second pin assignment. The north bridge chip includes a plurality of chip pins, and each of them corresponds to a first and second pin assignment. When the control circuit generates a first control signal, the pin assignments of the chip pins are defined as the first pin assignments. When the control circuit generates a second control signal, the pin assignments of the chip pins are defined as the second pin assignments.
