Abstract: A pair of binoculars which is convertible to a toy robot. The binoculars have a body to which leg tubes are attached, each leg tube having an ocular lens inserted in one end and an objective lens inserted in a second end. A focusing device is also attached to the body and is used to focus the lenses to sharply view a desired object.

When the activating switch is pushed, the switch contact is moved into position to complete the circuit with the battery contact and the resulting electricity from the battery travels to the motor.The control unit is a self-contained unit which is connected to the driving mechanism of the helicopter by a wire cord which may be stored in the helicopter's body.

Abstract: An apparatus and method are described for producing compact stranded conductors on single and double twist machines. This is achieved by preshaping and metering the preshaped wires to have generally sectored cross-sectional profiled complementary configurations and positioning and orienting the preshaped wires to substantially correspond to their positions and orientations in relation to the core wire in the final compact twisted conductor. The wires are metered to a double twist strander which is used to initially twist the preshaped wires about the core wire in a generally loose construction, and these wires are subsequently locked into abutment against each other when imparted a second twist to form the compact composite conductor.

Abstract: A computer inputed with a data base of potential call recipients and having an EIA RS-232 Data Communication Equipment interface drives an auto-call unit or dialer through a format conversion device to be compatible with the dialer EIA RS-366 automatic calling equipment interface. A line signalling device monitors the dial stream for conference connection commands and establishes a voice connection between the computer, an external or remote station and an internal or local extension upon receipt of such command. The computer thereupon disengages itself from the conference connection while maintaining the same between the remote and local stations. While a previously established conference connection may continue to be in progress, the computer is free to process a new sequence of dial digits from the data base to establish a conference connection between a next successive group of handsets in an automated, high speed repetitive manner.

Abstract: A method for automatic processing of electro-oculographic signals consists in carrying out visual stimulation of a patient at a preset stimulation angle and within a preset period of time, recording the signal of the bioelectric potention of the patient's eye, amplifying said bioelectric potential signal and limiting its spectrum, measuring the amplitude of the bioelectric potential signal at preselected instants of time, and subjecting the thus-measured values of the amplitude of said signals to statistical analysis to determine a constant electro-oculographic eye potential. The time instants at which the amplitude is measured are selected by determining the global extreme values of an absolute magnitude of the bioelectric potential within a preset number of stimulation cycles, comparing the modules of the thus-fixed global extreme values to one another and comparing the time intervals between the fixed global extreme values with the stimulation period.
