Abstract: A method (300) for controlling a display function of an apparatus such as a television signal receiver is capable of remedying a display locked in an extinguished state to thereby ensure that a usable display is provided. According to an exemplary embodiment, the method (300) includes steps of detecting a power on condition of the apparatus (330), determining whether at least one predetermined display parameter associated with the display function exhibits at least one predetermined value responsive to the power on condition (340), and adjusting the at least one predetermined display parameter if the at least one predetermined display parameter exhibits the at least one predetermined value (360).

Abstract: In a stereophonic system having sum and difference signals with expanded spatial imaging, localization of center audio materials more towards the center is accomplished by equalization of the (L+R) sum signal. The equalization comprises decreasing the bass response while increasing the treble response of the sum signal with the desired bass reduction being accomplished by the use of a gyrator to economically synthesize an inductance. Additionally, the equalizations in the (L+R) sum signal to reduce the signal at bass frequencies and to increase the signal at treble frequencies are switchable singly or in combination between “ON” and “OFF” modes.

Abstract: There is provided an acoustic sound reproducing apparatus for a first audio signal and having an input terminal for receiving a second audio signal, a selector switch and at least one loudspeaker. The at least one loudspeaker is driven by an output signal from one of the first or second audio signal through the selector switch. As a result, the acoustic sound reproducing apparatus, and the apparatus providing the second audio signal, can commonly use a single loudspeaker or set of loudspeakers. When the external audio signal is selected, the internal loudspeaker(s) becomes part of the external loudspeaker arrangement for a surround sound system. When more than one loudspeaker is used, the loudspeakers are connected to each other in series when they are connected to be driven by the external second audio input signal instead of each being driven by their respective amplifiers.

Abstract: A “floating” or “unipolar” DC supply is coupled to a filter comprising a pair of capacitors coupled in series across the supply output. Output voltages developed across the capacitors are applied to the supply inputs of an amplifier having an output coupled via a load to a common connection of the two capacitors. A bias supply, coupled in parallel with the filter, produces an output voltage representative of the relative values of the capacitor voltages which is fed back to an input of the amplifier via a threshold device. Under transient input signal conditions, which would tend to unbalance the filter capacitor voltages, the bias supply renders the threshold device conductive for diverting the transient from the amplifier input thus reducing the supply voltage imbalance and improving the transient recovery time of the amplifier.

Abstract: A head and upper body support system comprising three distinct supports: a head support and two upper body supports. The head support has a concave face contacting surface to receive the forehead of an individual therein. Each upper body support has an inclined lower portion to support and gradually lift the abdomen of the individual and an upper portion to support the corresponding shoulder, axilla (underarm), and side of the upper body. The upper portion of each upper body support has an arcuate groove formed in the side thereof to contour the axilla, which prevents the support from pressing against the breasts or chest of the individual or impeding the expansion thereof during breathing.
