  • Patent number: 4364046
    Abstract: A rotation angle detecting device with a pair of variable capacitors which are formed with a rotating object, i.e. a movable electrode, and two stationary electrodes disposed around the rotating object, so that the capacitors operate in a differential mode. Alternatively, the central electrode can be stationary while the two outer electrodes move with the rotating object. The capacitors are combined with oscillators, so that a signal varying with the rotation of the rotating object is provided by obtaining the difference between the output frequencies of the oscillators.

  • Patent number: 4363122
    Abstract: A DSI transmission system is described in which noise signal contrast is mitigated by transmitting not only active channels but also channels which carry background noise, the resolution of the background noise channels being varied in dependence upon the number of channels transmitted. In the described system, the DSI transmission is effected in superframes each of which consists of an overhead information frame and a plurality of digital message frames. The overhead information frame contains a word indicating the transmission status of each channel during the superframe, a code indicating the number of bits of each digital message, and maximum segment value information bits for each of the active channels which are transmitted using nearly instantaneous companding. Each of the remaining frames contains a digital message in respect of each active channel.

  • Patent number: 4361725
    Abstract: The apparatus comprises a wire sheet graphics tablet and a display apparatus, particularly a cathode ray tube, for receiving the signals transmitted by the graphics tablet. Alternating current flows through wires (5,6) of the tablet. The non-conducting plate (4) of the tablet is transparent and the wire sheets (5,6) are made up of transparent electrical conductors or of small conducting wires, which makes them practically invisible. The tablet is placed on the screen of the display apparatus. Between the screen of the cathode ray tube and the lower side of the graphics tablet, a transparent conducting and non-magnetic coating (8) is provided. In one variation, the current flowing through the layers of wire (5,6) is a high frequency current. The pen for the graphics tablet may be a metallic rod covered by a sheath of insulating material.

  • Patent number: 4361833
    Abstract: A multi-sensor alarm system and method of protecting a premises include at least one sensor circuit and an alarm circuit which together establish a two-wire closed loop electrical circuit path in which a wide variety of alarm sensors are accommodated. The sensors include two-contact configurations which are normally-closed or normally-open, as well as multiple-contact configurations which are characterized by both normally-closed and normally-open contacts. Each sensor differently changes the electrical parameters of the circuit path; and the alarm circuit includes a transistor which senses each parameter change, and a timer which generates an alarm signal whenever any of the sensors is actuated. Opening or closing the circuit path at any point therein will cause the alarm signal to be generated. A status indicator constantly monitors and supervises the status of the sensors in the circuit path.

  • Patent number: 4361755
    Abstract: A card having a longitudinal strip of encoded magnetic tape is inserted in a slot in a machine which feeds the card into the machine, reads the information on the strip, reverses the direction of the card and impacts the card to form an indentation to indicate a use of the card. The card is initially encoded for plural uses. Each time the card is used, the number of available uses is decreased on the information on the strip and corresponding indentations are impacted on the card.

  • Patent number: 4361885
    Abstract: The present invention relates to a system for channel-specific releasing and blocking of telephone channels in "outgoing" signaling converters and in "incoming" signaling converters of a pulse code modulation (PCM) system. Alarm signals which influence the signaling converters are generated in monitoring devices. The first alarm signal serves for accommodating the signal transmission and occurs immediately given faults in the system and occurs delayed given disturbances in the system. The second alarm signal effects a blockage of the telephone channels with respect to new seizure and is immediately triggered given disturbances in the system and given faults in the system. Given this method of alarm, a channel-specific and time-differentiated release and blocking of telephone channels occurs independently of the presence of a central processing device in a signaling converter equipment.

  • Patent number: 4359717
    Abstract: To increase the responsiveness of a vehicle alarm system to, for example, unauthorized entry through windows, jacking up for removal of parts or vehicle theft as well violent impact by another vehicle, at least one position sensitive sensor has its output signal, which represents the instantaneous position of the vehicle stored after activation of the alarm system. Any change in that position is detected and triggers a warning device when the deviation exceeds a predeterminable amount. The position sensitive sensor may be a fluid-filled vessel the internal resistance of which is measured in a resistance bridge or it may be a variable inductance sensor which is connected to a frequency generator whose output signals are counted and compared with a given value. The system according to the invention may also serve as an accelerometer.

  • Patent number: 4357495
    Abstract: The direct current line feed for a telephone subscriber's line is derived from a variable voltage source connected to the line. In one case, the source is series connected in one leg of the line while in the other case it is connected across the line. In the first case there is a constant current source across the line while in the second case the voltage source is a constant current device. In both cases a pair of matching resistors is connected across the line with the center tap grounded to provide a high resistance balanced termination for the line. In both cases a high impedance monitor is connected across the line to monitor the voltage conditions on the line, and this, via a control circuit controls the voltage source and the separate constant current device if provided. This enables line voltage to be adjusted to take account of line length without introducing undesirably large dissipation.

  • Patent number: 4357499
    Abstract: In prior art acoustic test boxes, which can function as small anechoic chambers, it has been difficult to attain a frequency-independent pressure field at the test point without simultaneously increasing the frequency dependency of the velocity field, whereby tests of objects which are partly pressure sensitive and partly velocity sensitive are vitiated by errors. An elongated acoustic test box provided exclusively with curved surfaces and with space for an effective sound absorbent behind the test object overcomes this problem and at the same time provides improved acoustic insulation against low-frequency ambient noise. In a particularly appropriate embodiment the box (1) is shaped like an egg supported at its narrow end on a support (2) and divided about two-thirds of the way up into a bottom part (4) and a cover (5), the latter containing a sound source (10).

  • Patent number: 4357532
    Abstract: Encoded magnetic strip cards are fed into apparatus which reads encoded data on the card. The card is fed into and out of the apparatus through a passageway defined by a guide which also serves as a mount for mechanical and electronic components. The guide is precisely constructed so that the thickness and width of the passageway are slightly greater than the corresponding dimensions of the card and the card does not jam in the passageway. In one form of the invention the guide is formed of two generally T-shaped, overlapping, interfitting members. In a second form of the invention the guide is formed of two opposed T-shaped side members and two plates relieved at their edges to receive the legs of the side members.
