Abstract: ABSTRACT    An ultrasonic surveillance system which emits pulse--like ultrasonic waves to an area under surveillance, which statistically compares a reflected-wave pattern established by receiving ultrasonic waves reflected from the under surveillance with a predetermined reference pattern, and which produces an alarm signal when these two patterns are not in agreement.  In order to exclude ultrasonic noise having a relatively small amplitude from the reflected-wave pattern, a difference component between a pattern of frequencies of emitted ultrasonic waves and a pattern of the other frequencies is used as the reflected pattern.  The frequency components other than those of emitted ultrasonic waves are integrated and, when the integrated value exceeds a predetermined value, the transmission of an alarm signal is interrupted so as to prevent the system from being erroneously operated by ultrasonic noise having a large amplitude.  The number of peak values in the reflected pattern is counted and, when the counted value exceeds a predetermined value, the transmission of an alarm signal is also interrupted.

Abstract: CONSTRUCTION OF A TELEPHONE INSTRUMENT            Abstract:   To reduce manufacturing costs of telephone instruments it is desirable to secure components to housing members and secure housing members to one another without the use of fasteners.  In the past this has been accomplished by the use of flexible latch elements that are deflected from their normal position in the process of assembly, and then return to their normal position to perform their latch function when assembly is complete. The problem with this arrangement is that impact, such as occurs during shipping or when a telephone instrument is accidentally dropped, has been found to cause the flexible latch elements to deflect and release the housing members and/or components they are intended to secure.  The disclosed telephone instrument solves the problem of securing the components in place by having integral flexible latch elements extend alongside of a wall of one housing member and integral blocking elements included in the mating housing member.  These elements are arranged so that when the two housing members are joined together, the blocking elements extend between the wall and the latch elements and prevent the latch elements from deflecting while the housing members are joined.  The disclosed telephone instrument solves the problem of securing the housing members together by interlocking one end and latching the other end of the housing members.  The latching is achieved by having inflexible latch elements integral to each housing member move into interlocking engagement by means of flexing the adjacent wall of one housing member.

Abstract: Abstract of the Disclosure An output circuit and a biasing circuit for biasing an oscillation circuit comprise a current mirror circuit.          The DC level of the output signal from the oscillation circuit is level shifted by controlling the current of the current mirror circuit comprising the biasing circuit and the output circuit.  This control is per-formed by suitably determining the number of diodes and the resistances of the resistors making up the current mirror circuit.  The biasing circuit of the oscillation circuit may thus be utilized as the level shifting circuit, the DC level of the output signal of the oscillation circuit may be set to a predetermined level, and fluctuations in the duty ratio of the oscil-lation output may be suppressed.

Abstract: MAGNETIC STRIPE CARD AUTHOR                 Abstract of the Disclosure Method and apparatus for registering selected new magnetic data on magnetic stripe cards for use-in a vending machine account control system, such as is employed with a photocopy machine.  Specifically, card author is provided which consists of a keyboard with data entry and operation control keys, keyboard scanning means, an input/output storage port and a bus connector which can be coupled directly to a duplicator controller.  Upon connection of the card author to the duplicator controller, and with the duplicator controller in a card author mode, the duplicator controller initiates interactive operation with the card author in order to request certain information not normally accessible to manual manipulation as by a key operator. Through its display, the duplicator controller requests entry of at least three different types of values, a value representing worth of a card to be authored, an account number, and a delimiter value.  The delimiter value restricts field of use to specific machines and time periods and may be an expiration date, a department number, a system identification number, or any combination of the above.  A specific protocol for use of the card author assures proper encoding of magnetic cards.

Abstract: ABSTRACT OF THE DISCLOSURE           Various methods and systems for television transmission, as well as for scrambling a plurality of input signals for secure transmission thereof, are disclosed.  The scrambling technique, in one form, includes modulating an in-phase component of at least one carrier signal in response to one and then another of a plurality of input signals in a sequence of time intervals such that parts but not all of the one and another of the input signals are carried by the in-phase component.  A quadrature component of the carrier signal is similarly modulated in response to the one and another of the plurality of input signals in the sequence of time intervals such that the in-phase and quadrature components together carry the one and another of the input signals in their entireties.  The modulated in-phase and quadrature components are com-bined for transmission.  A decoder for unscrambling the plurality of signals and selecting one is also dis-closed.  The various television transmission methods and systems involve provision of additional audio signals, in scrambled or unscrambled form, with the normal television audio and video signals so that multi-lingual program service as well as other services can be provided.

Abstract: ABSTRACT OF THE DISCLOSURE     An article surveillance system employs a label or tag containing a non linear impedance element, such as a semiconductor diode, connected to a metal antenna loop configured to pick up two distinct radio frequency transmissions displaced on either side of a selected center frequency.  The non-linear impedance element connects opposing sides of a closed loop section at one end of the antenna to form a tuned tank circuit having a resonant frequency twice that of the selected center frequency. A first transmitter generates a tone modulated radio frequency displaced on one side of the center frequency, and a second transmitter generates a continuous wave radio frequency displaced from the center frequency on the other side.  Both transmitter signals are fed separately to respective orthogonally disposed dipole radiating antenna strips located on opposite sides of a surveillance area with the dipole strips for the different frequencies being disposed at right angles on each side while those for the same frequency are also at right angles to one another on opposite sides, thus producing cross polarized transmission of both frequencies within the surveillance area.  The two different frequencies picked up by the transponder antenna are mixed by the non-linear impedance causing the tank circuit to resonate at a single higher frequency equal to their sum, which is double the center frequency;  that resonant frequency is reradiated to be picked up by receiver antennas on each side to be detected by a very narrow band receiver responsive to the sum frequency.  The modulating tone signal is derived from the received signal to produce a gradually increasing charge that is compared against a preselected threshhold level to trigger an alarm for a fixed interval only when the detected signal is of a sufficient strength and duration.
