摘要： An optocoupled line circuit is arranged with a diode bridge providing uniform direction current flow so as to eliminate the mechanical switch hook contact of the prior art. A zener diode is used to bridge a clipped version of AC ringing current across the optocoupler when the circuit is in the on-hook condition. Current presented to the optocoupler from a line control device allows current to flow from the telephone line through the line interface circuit.

摘要： A combined loop current sink, battery detector, and ringing detector circuit as used in a channel unit at a telephone central office connection to a digital loop carrier circuit, to provide off-hook and on-hook signaling to analog switching circuits, and to simultaneously receive normal battery and ringing signals from the analog switching circuits. The combined circuit includes tip and ring connections to the digital loop carrier circuit to provide telephone service, a loop input controlled by logic circuits, at the telephone central office, and a battery output connected to the logic circuits. A first optocoupler, is connected to the loop input and also to ground, for providing a floating voltage coupling for the loop input to the circuit. A second optocoupler, is connected to the battery output and also to ground, for providing a floating voltage coupling for the circuit output. A transistor circuit has an input coupled to the first optocoupler and an output coupled to the second optocoupler. The logic circuits send an on-hook signal by applying a zero volt ground signal to the loop input so that no current flows through the first optocoupler, and an off-hook signal by a positive volt signal to same input so current flows through the first optocoupler.

摘要： In an optical telephone wherein amplitude modulated light is converted to sound by applying the modulated light to an enclosed volume of gas wherein the volume and/or pressure of gas varies in synchronism with the instantaneous energy of the modulated light and wherein an optical fiber is used as the transmission element, the improvement is provided by the means to more uniformly distribute the optical energy in the gas cell causing an improved and more efficient conversion of the modulated light directly into sound.The means can be provided by covering the light entering side with a positive lens and positioning the optical fiber at the focal point of the lens.

摘要： The disclosed four-wire to two-wire converter employs a pair of dual detector opto-isolator circuits to both linearize the converter transfer characteristic and eliminate signal feedback between ports. This is accomplished by feeding back the signals transmitted by the transmit portion of the four-wire port through the auxiliary detector of the opto-isolator circuit connected across the two-wire port to prevent signal feedback to the receive portion of the four-wire port. This opto-isolator feedback arrangement eliminates the need for complex feedback and impedance matching circuitry thereby enabling direct connection of the opto-isolator circuits to the communication paths while also rendering the converter circuit transparent to signals appearing thereon.

摘要： Digital data is optically broadcast through an environment by controllably switching the brightness or chrominance of LED solid state lamps, or of other illumination sources (e.g., television screens and backlit computer displays). This optical data channel is useful to convey cryptographic key data by which devices within the environment can authenticate themselves to a secure network. In some embodiments, the optical modulation is sensed by the camera of a smartphone. The row data output by the smartphone's camera sensor is processed to extract the modulated data signal. In some monochrome embodiments, data communication speeds far in excess of the camera's frame rate (e.g., 30/second), or even the camera's row rate (e.g., 14,400/second) are achieved. Still greater rates can be achieved by conveying different data in different chrominance channels. A great number of other features and arrangements are also detailed.
