Abstract: The present invention provides an electroencephalogram measurement structure formed by an ear-hanging structure and a second circuit board. The ear-hanging structure includes a body. An ear-hanging member is disposed at the extension of the body. The body can be worn on the ear via the ear-hanging member. In addition, a first reference electrode and a second reference electrode are disposed on the body and coupled to a first circuit board. The first circuit board is coupled to an electrical jack; the second circuit board is coupled to the electrical jack via an electrical plug. Thereby, the electroencephalogram measurement can be performed simply by wearing the ear-hanging member on the ear of the person under test. Hence, the problems of complicated wiring and inconvenience in wearing can be solved concurrently.

Abstract: A transceiver with wake up detection includes a primary control unit, a transmission unit and a receiving unit, the transmission unit comprises a first logic set, a second logic set, a third logic set, a first loop, and a second loop. The first loop outputs a first differential signal, and the second loop outputs a second differential signal.

Abstract: A three-dimensional (3D) pointing device includes a housing, an inertial measurement unit, a data processing unit, a communication unit, and a power unit. The housing has a rough surface, and the inertial measurement unit is provided inside the housing and in contact with the housing. The inertial measurement unit includes a gyroscope and an accelerometer. The data processing unit is used to integrate data from the gyroscope and the accelerometer to generate an output data, so as for the communication unit to send out the output data. The power unit provides power to the 3D pointing device. The 3D pointing device enables the user to execute pointing control in a 3D space and allows the user to input commands by means of the rough surface. Thus, the 3D pointing device features both convenience of use and a small physical volume.

Abstract: A system for transferring electric power and signals via a power line by time-division multiplexing includes a power line, electronic-circuit units, and controllers. The power line includes a first transmission line and a second transmission line. The first transmission line is connected with a first switch in series and is therefore divided into a source end and a loading end. The electronic-circuit units are connected in series between the loading end and the second transmission line. The controllers are electrically connected with and are configured for synchronously controlling the first switch and the electronic-circuit units. When the first switch is closed, electric power is transferred from an electric power source to the loading end, and when the first switch is opened, the electronic-circuit units transfer signals via the loading end. The system features simple circuitry and effectively reduces noise in signal transmission.
