Abstract: A toy accessory includes an arch and a connector attached to each end of the arch. The connector is configured to attach to either of a top rail of a juvenile product and an edge of a play mat. The connector includes an arch connection portion configured to connect to the respective end of the arch and also includes a receiving portion configured to receive either of the top rail of the juvenile product and the edge of the play mat. The connector further may include a play mat connection portion configured to connect to a surface of the play mat.

Abstract: The proposed phase lock technique uses various feedback loops to lock the frequency and phase of a CATV modulator output signal to that of an off-air signal without directly measuring the output frequency. One embodiment includes a tuner for receiving the off-air signal and generating an intermediate frequency signal and a phase-frequency detector for comparing the frequency and phase of the intermediate frequency signal generated by the tuner with the frequency and phase of an intermediate frequency signal generated by the modulator based on a reference input signal. The output of the phase-frequency detector is used to control the reference input signal into the modulator and the reference input signal to the tuner such that the frequency and phase of the modulator output signal is locked to the frequency and phase of the received off-air signal.
