Responsive to this request, a translation of the text phrase is selected from a set of available translations. The selection is based on actions by friends of the member in the social network, the actions being associated with the set of available translations. These actions can the viewing of or approval of translations by the friends, for example. The selected translation is then presented to the member requesting the translation.

Abstract: An automatic charging station for an autonomous mobile machine includes a base, a housing, and a signal transmitter. The base is mounted on the ground or on a planar surface. The housing is rotatably mounted on the base, having at least one guide member and a plurality of electrically conductive members on a surface thereof. The electrically conductive members are located on the housing. The signal transmitter is mounted on the housing for transmitting a signal. When the autonomous mobile machine senses the signal transmitted by the transmitter while moving, the autonomous mobile machine moves along a route towards the housing and then forces the guide member to enable the housing to rotate for facing and accommodating the autonomous mobile machine and to further enable the autonomous mobile machine to contact against the housing to have its electrodes in contact with the electrically conductive members for charging.

Abstract: A communications receiver and method are provided for receiving a transmitted signal from a transmission channel having a low-pass filter characteristic. The receiver includes a receiver input for coupling to the channel and a switched capacitor pre-emphasis filter coupled to the receiver input. An analog-to-digital (A/D) converter is coupled to an output of the pre-emphasis filter. An equalizer is coupled to an output of the analog-to-digital converter.

Abstract: An inexpensive synchronous detection module is disclosed for a sideband signal receiver that provides for flexibility in design of the tuner. The detection module is adaptable to detection of upper or lower sideband signals. One embodiment includes an analog-to-digital converter, a Hilbert transform filter, a sideband selection switch, a complex multiplier, a carrier recovery. loop, a matched filter, and a decimator. The analog-to-digital converter oversamples an intermediate frequency (IF) signal from the tuner, and the Hilbert transform filter generates a Hilbert transform of the digital IF signal. An analytic IF signal can be generated from the digital IF signal by multiplying the Hilbert transform of the digital IF signal by j(=sqrt(−1)), and adding the resulting imaginary-valued signal to the digital IF signal. The sideband selection switch can “flip” the analytic IF signal by inverting the imaginary-valued signal.

Abstract: An adaptive equalizer for use in a communication receiver that prevents equalizer operation divergence in response to slicer errors in a high noise communication application. The equalizer uses the difference between an equalized sample value and the nearest constellation point determined by the slicer both as the equalizer adaptation value and as a control value to selectively enable or minimize (disable) adaptation modifications. The difference is compared to a threshold value to determine whether the difference should be applied to the equalizer for adaptation purposes or a minimal value to prevent equalizer divergence in response to significant slicer errors. The threshold value is determined as a function of the ratio of the probability of correct slicer determinations and the probability of incorrect slicer determinations for a given sample value and a given signal to noise ratio.
