    Abstract: Systems, methods, and computer-readable media for determining long binary sequences having low autocorrelation functions using evolutionary processes are disclosed. Biphase sequences are found with low peak sidelobe values meeting a predetermined criterion, e.g., threshold low auto-correlation function, including application of semidefinite programming in connection with determining an initial population, and evolving the population with an evolutionary algorithm to bits of the biphase sequences including bit flipping. The found biphase sequences can be communicated to a variety of applications, including wireless communications technologies.

    Abstract: Spectrum sensing in wireless communications is provided to identify utilized and/or unutilized frequency bands reserved for primary users using a cyclostationary beamforming approach. An adaptive cross self-coherent restoral (ACS) algorithm can be utilized to extract signals of interest (SOI) at unique cycle frequencies related to primary and/or secondary users from an antenna array measurement. Based on the SOI, one or more users of the spectrum can be identified or the spectrum can be regarded as vacant; this can be based on lobe identification in the frequency spectrum of the SOI, in one example. This mechanism is less complex than traditional cyclic spectrum analysis methods. The cyclostationary beamforming based approach is more effective than the energy detection method. Also, the need for quiet periods in spectrum sensing is eliminated when using this mechanism such that signals can be transmitted simultaneously with receiving signals over the antenna array.

    Abstract: Control apparatus used in connection with commodes automatically moves a trip lever for flushing the commode and includes a member adapted to be connected to the trip lever for moving between an initial position and a flushing position to cause the trip lever to raise a drain valve to its open position. A spring moves the member to its flushing position, and a person-operated device causes energy to be stored in the spring and releases subsequently the energy from the spring to move the member toward its flushing position. A latching device connected to the member connects releasably the member and the trip member for moving it and the valve against the force of water pressure acting on the valve until the water pressure equals the force applied by the spring after sufficient water discharge. As a result, the spring commences again to move the member after the sufficient water discharge has taken place to release the latching device so that the member becomes free of the trip lever and the flushing mechanism can complete its normal flushing operation.
