摘要： An apparatus includes first and second accelerometers, a display device implemented in a vehicle, and a controller. The display device displays, to a user, a cursor relative to one or more objects. The first accelerometer generates a first signal representing an acceleration of the vehicle due to motion of the vehicle. The second accelerometer is worn by the user and generates a second signal representing both an acceleration of the user within the vehicle and the acceleration of the vehicle due to the motion of the vehicle. The controller isolates, based on the first signal, i) the acceleration of the user within the vehicle represented in the second signal from ii) the acceleration of the vehicle represented in the second signal. The controller moves the cursor relative to the objects based on the acceleration of the user within the vehicle as isolated from the acceleration of the vehicle.

摘要： A process of controlling a flow of data in a wireless network providing wireless access to the wireless network by wireless devices is disclosed. Data is received from a wireless device by a network device, through one access point of a plurality of access points in communication with the network device, indicating a client identifier for the wireless device. The client identifier is forwarded to an authentication server and the network device mediated authentication of the wireless device with the authentication server. Thereafter, data packets received from portions of the wireless network and from the plurality of access points are evaluated and the received data packets are passed to portions of the wireless network and to the plurality of access points, based on the evaluation of the received data packets. In addition, the network device periodically polls for a status of the wireless device from the access point.

摘要： A decision feedback equalizer circuit employing a current mode finite impulse response (FIR) filter. A decision feedback equalizer circuit comprises an attenuator block for scaling a received voltage signal, a first transconductor (voltage-to-current converter) for converting the received voltage signal to a current signal, a current mode finite impulse response (FIR) filter for adding or subtracting current increments from the current signal and generating an equalized current signal, a second transconductor (current-to-voltage converter) for converting the equalized current signal into an equalized voltage signal, a positive slicer block for determining when the equalized voltage signal achieves a positive threshold level, a negative slicer block for determining when the equalized voltage signal achieves a negative threshold level, and a plurality of delay lines coupled respectively to the slicer blocks and to the current mode FIR filter for providing tap enable signals to the current mode FIR filter in response to signals received from the slicers. The decision feedback equalizer circuit may further comprise a baseline wander correction block for providing a correction current to the current mode FIR filter to compensate for baseline wander in the input voltage signal, and an adaptation block for providing compensation signals to the current mode FIR filter to insure that the equalized voltage signal conforms to a predetermined format.
