OTAR technology created by NSA inventor, innovator, and author, Mahlon Doyle [7] was operationally introduced to the US Department of Defense in 1988. Lieutenant Commander David Winters, an American naval officer in London and code master during the final years of the Cold War, [8] was first to recognize the necessity and security potential of OTAR.
The operational transconductance amplifier (OTA) is an amplifier that outputs a current proportional to its input voltage. Thus, it is a voltage controlled current source (VCCS). Three types of OTAs are single-input single-output, differential-input single-output, and differential-input differential-output (a.k.a. fully differential), [ 1 ...
An over-the-air update (or OTA update), also known as over-the-air programming (or OTA programming), [1] is an update to an embedded system that is delivered through a wireless network, such as Wi-Fi or a cellular network. [2] [3] [4] These embedded systems include mobile phones, tablets, set-top boxes, cars and telecommunications equipment.
Terrestrial television, or over-the-air television (OTA) is a type of television broadcasting in which the content is transmitted via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna.
Schematic symbol for an OTA has inverting (V in-) and noninverting (V in+) inputs, power supply lines (V + and V −), two biasing inputs (I abc and I bias), and a single output current I out. The LM13700 is an integrated circuit (IC) containing two current -controlled operational transconductance amplifiers (OTA), each having differential ...

Off-the-record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR uses a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function.
