An implantable loop recorder (ILR), also known as an insertable cardiac monitor (ICM), is a small device that is implanted under the skin of the chest for cardiac monitoring, to record the heart's electrical activity for an extended period.
Loop recording is the process of recording audio continuously to an endless tape (if magnetic tape is used) or to computer memory, or recording video feeds (such as from video surveillance or camera signals) on a video server. [1]
Loop recorder may refer to: Digital loop recorder, a type of closed-circuit television security camera; Implantable loop recorder, a medical diagnostic device
An Event Recorder can be worn on the body for up to 30 days. [6] A Mobile Cardiac Telemetry unit is a wearable monitor that detects, records, and transmits heart rhythms for up to 30 days. For long term use, an Insertable Cardiac Monitor is placed under the skin and automatically detects and records abnormal heart rhythms for up to 5 years. [7]
Initially, this mechanism was to be implemented in a reel-to-reel audio tape recorder. [3] [4] Later, Cousino developed a plastic case that could be hung up on some existing tape recorders. [5] This cartridge was marketed by John Herbert Orr as Orrtronic Tapette. [6] In this generation, the magnetic coating of the tape was wound on the inside ...
On a standard reel-to-reel tape recorder, one loop can be no more than few seconds long. Some composers were satisfied with this approach, but there were other methods to allow for longer loops. For example, placing two reel-to-reel machines side by side with the tape path running from the one to the other.
The first dedicated loop device was the Paradis LOOP Delay. [6] The Paradis and other models had volatile memories, forcing composers to develop fresh loops live in front of their audiences — and thus, live looping came into existence. Roland and DigiTech loop pedals entered the market in 2001, around the same time DJ mixing gained popularity ...
A 4-inch (100 mm) underwater locator beacon, with ballpoint pen for scale A ULB attached to a bracket on a cockpit voice recorder. An underwater locator beacon (ULB), underwater locating device (ULD), or underwater acoustic beacon is a device that emits an acoustic pulse intended to guide searchers equipped with a suitable receiver to the location of the beacon underwater.
