Abstract: An exercise apparatus with suspension system is provided. The exercise apparatus may include one or more of the following; a frame suspension system, a base suspension system, a deck suspension system, or a chassis dampening system. The advantage of exercising apparatus with suspension system is that it may prevent or mitigate vibration and sound disturbances of the exercise apparatus when it is used.

Abstract: A wireless system includes a base station, user equipment (UE), and at least one wireless device capable of communicating with the base station. The wireless device and the UE belong to an area network. The UE is capable of communicating with a base station directly and communicating with the base station through the wireless device. The wireless device communicates with the base station wirelessly and communicates with the UE either wirelessly or through cable.

Abstract: A hybrid beamforming apparatus and method are proposed for a communication system. The hybrid beamforming apparatus includes a plurality of antennas, a plurality of FFT, a plurality of hybrid weight-coefficient generators and a plurality of adders. In each of the hybrid weight-coefficient generators, the weight coefficient for each subcarrier is calculated by a time-domain correlation matrix and a cross-correlation vector, which is calculated by a frequency domain signal and a training signal. The hybrid beamforming apparatus and method according to the present invention can enhance immunity for multipath effect with lower system complexity.
