摘要： A method for protecting user data during an audio interaction includes various operations performed by a processing system including at least one processor. In one example, the operations include detecting an audio signal that is part of an interaction between a user and another party, converting the audio signal into a string of text, detecting that the interaction is likely to put sensitive data of the user at risk, based on a comparison of the string of text to a library of interactions that are known to put sensitive data at risk, and sending an alert to notify the user that the interaction is likely to put the sensitive data of the user at risk, wherein the alert is sent to prevent the user from providing the sensitive data to the another party, and wherein the method is performed contemporaneously with an occurrence of the interaction.

摘要： An arrangement providing a monitor-on-hold feature for telephone station apparatus. The exemplary apparatus includes a handset transmitter and receiver, a speaker, and four user control buttons. A user is given the capability to move a connection for a first call from the handset to the speaker by simply actuating one of the buttons, the PRIVACY button. A connection is thereafter completed to the handset to answer a second call in privacy by actuating a second button, the NEWCALL button, while continuing to monitor the first call via the speaker. The capability to move connections is provided by a microprocessor-controlled switch included within the apparatus to selectively interconnect the two communications channels used for the two calls, with the handset and the speaker. Alternatively, the moving of connections is effected within the switching system serving the telephone station.

摘要： An automatic telephone hold releasing circuit for a plurality of telephone sets connected in parallel across a pair of wires of a subscriber's office line, which can automatically release a call placed on hold at one of the telephone sets even when the particular telephone set is on hold with its handset placed in the on-hook position. The circuit comprises means for detecting a voltage drop occurring in the voice-circuit when the handset of a telephone set other than that with which the call has been initially answered is unhooked, means for comparing the dropped voltage with a voltage present when the call was put on hold, and means responsive to an output of said comparing means for deenergizing a relay to open its contacts in response to the voltage drop and automatically release the initially answered telephone set.

摘要： A hold circuit for use with a single line telephone which may or may not be equipped with extension instruments. The circuitry in response to the momentary operation of a manual switch actuates a siliconcontrolled rectifier to place a resistive load across the telephone line thus allowing the subscriber at the basic telephone instrument to go "on hook". Subsequent removal of the basic instrument handset from the hookswitch or an extension phone going "OFF HOOK" will cause the resistive load to be removed. Also included is a hold release circuit which automatically disconnects the hold circuit after a predetermined period of time.

摘要： There is disclosed an improved hold circuit arrangement for controlling the hold function in a key telephone line circuit without introducing an undesired series impedance in the longitudinal path of the telephone line during any of the line circuit's normal operating states. The improved circuit arrangement employs a combination of an opto-coupled energizing circuit for detecting and responding to the presence of d.c. current on the telephone line during the hold state and two miniature relays which operate to establish a condition of electrical isolation between the opto-coupled energizing circuit and the longitudinal path of the telephone line in all operating states except during the momentary transition from the line busy to the line hold state. In another embodiment of this invention, logic circuitry is associated with the opto-coupled energizing circuit to provide lamp control indicative of the line state. The invention reduces the overall cost and profile of the line circuit while providing a means for eliminating a common cause of longitudinal imbalance during the hold state characteristic of conventional line circuit technology.
