Ringing noise from an electromechanical telephone Example of a short digital tune which could be used as a ringtone on a mobile phone. A ringtone is the sound made by a telephone to indicate an incoming telephone call. Originally referring to the sound of electromechanical striking of bells or gongs, the term refers to any sound by any device ...
The laws regulating driving (or "distracted driving") may be subject to primary enforcement or secondary enforcement by state, county or local authorities. [1]All state-level cell phone use laws in the United States are of the "primary enforcement" type — meaning an officer may cite a driver for using a hand-held cell phone without any other traffic offense having taken place — except in ...
The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
When the switching system directs a call to a particular subscriber line, a relay on the line card connects the ringing generator to the subscriber line. The exchange also sends a ringing tone to the calling party. When the called party answers by taking the telephone handset off the switchhook, the subscriber's telephone draws direct current ...
Amazon Echo devices have Sidewalk enabled by default and do not inform their owner about it. The feature can be disabled via the official app. [10] A number of prominent news publishers, including The Guardian, [13] ArsTechnica, [11] CNET, [14] PCMag, [15] Click2Houston, [16] and Bleeping Computer, [17] expressed concern with opt-out nature of the network and published guides how to disable ...
Phantom vibration syndrome or phantom ringing syndrome is the perception that one's mobile phone is vibrating or ringing when it is not. Other terms for this concept include ringxiety (a portmanteau of ring and anxiety), fauxcellarm (a portmanteau of "faux" /foʊ/ meaning "fake" or "false" and "cellphone" and "alarm" pronounced similarly to "false alarm") and phonetom (a portmanteau of phone ...
"If you'd like to make a call, please hang up and try again. If you need help, hang up and then dial your operator. This is a recording."). A single burst of off-hook tone is sometimes used to indicate to a party that the call is being transferred, notably at 1-800-BELL-SOUTH (800-235-5768).
In electrical circuits, ringing is an oscillation of a voltage or current.Ringing can be undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted [citation needed]; it can increase settling time for the desired final state; and it may cause unwanted triggering of ...
