    Abstract: Customer services terminal input connected between telephone exchange and outputs. Interface circuits provide service between input and outputs Test means applies test conditions to interface circuits and/or to outputs associated with the interface circuits, and/or to ring/tip pairs associated with interface circuits, and/or to telephone lines associated with interface circuits Other interface circuits service input to other outputs Test means analog-to-digital converter includes reference input, analog measuring input, ground potential input, and test output Normally de-energized calibration relay has normally-closed switches and normally-open switches. Normally-closed switch connects reference voltage to reference input. Another normally-closed switch connects analog measuring input to test means generated voltage. Calibration switching means energizes calibration relay to connect analog measuring input to reference voltage via normally-open switch, to connect reference input to source of ground potential via another normally-open switch to generate calibration output useful for determining test results output when calibration relay is de-energized.

    Abstract: A sound activated toy vehicle includes a body, a chassis, and a motor. The chassis accommodates the body and has at least a front wheel and a rear wheel. The motor is drivingly connected to at least one of the front wheel and the rear wheel. The toy vehicle also includes a sound transducer configured to generate an electrical signal in response to detected sound. The toy vehicle also includes a controller having an input electrically connected to the sound transducer and an output electrically connected to the motor. The controller changes the output to the motor when the electrical signal is received by the input from the sound transducer. The toy vehicle also includes a vehicle accessory having an exterior portion. The vehicle accessory is mounted for movement between a first position and a second position by mechanical power from the motor.

    Abstract: The disclosed audio signal processing system produces an acoustic signal in a listening space and includes devices for generating a desired volume signal, a noise signal representative of ambient noise conditions in the listening space, and an audio signal. The system further includes a variable gain amplifier for amplifying the audio signal in response to a gain control signal and a device for generating the gain control signal in response to a volume control signal. The volume control signal is generated in response to the noise and desired volume signals so that the volume control signal increases in response to increases in the noise signal. The volume control signal increases at a rate of increase and the rate of increase decreases as the volume control signal increases.

    Abstract: An electronic bait box assembly for storing earthworms includes a box for containing earth and earthworms. A lid is removably attached to the box for closing the box. A voltage unit is coupled to the bait box and the voltage unit is in electrical communication with an interior of the box. Moreover, the voltage unit is placed in electrical communication with the earth that is positioned in the box. The voltage unit induces an electrical voltage through the earth when the voltage unit is turned on. In this way the voltage unit urges the earthworms to move upwardly in the earth thereby facilitating a user to remove the earthworms for fishing bait.
