Abstract: In various embodiments, promotions are featured on mobile gaming devices.

Abstract: A magnetic drape comprises a drape body made of a flexible material. The drape body has a panel portion having an undersurface adapted to be laid on an uneven body and a top surface, and a given thickness between the undersurface and the top surface. A plurality of magnet units are within the flexible material of the drape body, with each said magnet unit comprising a shielding material in the shape of a cup oriented to have a bottom wall facing toward the undersurface of the drape body, and a magnet received at least partially in the cup. The magnet comprises two or more sections arranged to expose opposite polarity on a top surface of the magnetic drape, with each said section having opposite polarities oriented vertically.

Abstract: Re-synchronization of digital audio signals before converting the signals from digital to analog form using a stable clock reduces uncertainties in the timing of the audio signal.

Abstract: A magnetic pickup which contains both resistance and stray capacitance is terminated by a negative impedance of a kind which compensates for the stray capacitance and part of the resistance, and causes a pole to be produced at a low frequency. This results in the formation of a virtually perfect integrator. Preferably the integrator is followed by a pedestal filter for receiving the output signal of the integrator, and has a zero phase shift point at a predetermined frequency higher than the frequency of the pole and within the frequency band, and has an intermediate frequency band transfer characteristic which increases at a rate of approximately equal to the decrease in transfer characteristic of integrator.

Abstract: Apparatus for reducing the consumption of power by controlling the application and removal of power to and from a plurality of load circuits connected to AC power sources of the same or different phases in response to the movement and absence of movement of an object within a prescribed area.
