    摘要: An output apparatus includes a first source of a first signal having a first state or a different second state; a second source of a second signal having a first state or a different second state; and a circuit structured to output a vital output including a first state when the first state of the first signal corresponds to the first state of the second signal and, otherwise, including a different second state. At least one of the first signal and the second signal is a static signal. The other one of the first signal having the first state and the second signal having the first state is a dynamic signal. When at least one of the first signal has the different second state of the first signal and the second signal has the different second state of the second signal, the vital output includes the different second state.

    摘要: A signaling apparatus that includes a transmitter having a step-square wave generator for generating a signaling waveform, which waveform is composed of a plurality of square wave signals, and which has an information signal encoded thereupon. The apparatus may also include a signaling waveform receiver, disposed on the railcar, and an information signal decoder, connected to the receiver, for extracting the information signal from the receiver. The stepped-square wave generator produces square waves such that a portion of the duty cycle of one of a plurality of square wave signals overlaps at least a portion of the duty cycle of at least one other of the plurality of square wave signals. A method for signaling in which a multi-stepped square waveform is generated, includes a waveform having a series of superimposed square waves, each of which having preselected amplitudes and duty cycles. An information signal can be encoded upon the multi-stepped carrier waveform such that a coded-carrier signal is created.

    摘要: A coded railway track circuit apparatus is disclosed having the capability of operating during periods of low vehicle activity in a reduced power standby mode. This is accomplished by switching circuitry which interrupts power to most of the components within the track circuit apparatus in response to the recognition by standby initiation circuitry of a preselected standby initiation signal. Power to fail-over indicators which would normally be activated due to a power failure is also interrupted by fail-over interrupt circuitry. During the standby mode, monitor circuitry remains active to recognize occurrence of a preselected wake-up signal. When the wake-up signal is received, full power is restored, thus resuming normal operation. Operation of the fail-over systems is also then re-established.

    摘要: This invention relates to a combination comforter and sleeping bag, having top and bottom fabric portions each sized to substantially cover the top and end portions of a single bed. The top and bottom fabric portions are removably secured about their sides and bottom portions. Indicia in the characterization of the body of a person, animal, creature, monster, alien or thing is disposed upon one side of the top fabric portion. A head portion is removably secured along the top side of the bottom portion, with indicia in the characterization of the head of a person, animal, creature, monster, alien or thing dipicted upon the body portion. Preferably the head portion includes an audio device with battery, switch and speakers disposed in the head portion. The head portion may also include at least one visual light source with battery and switch. Where both an audio device and visual light source are included in the head portion, a common switch and battery source may be employed.
