  Receiver
A receiver (radio) is an electronic device that receives a radio signal from a transmitter and converts it to useful information in the form of sound, pictures, computer data, navigational position information, etc. An external receiving antenna may be required.
A receiver (electronics) is a combination of a radio broadcast tuner and an amplifier for the speakers, as well as selection for sources such as a CD or tape, and adjustments for audio, such as a graphic equalizer or basic tone controls.
A receiver (firearms) is the part of the firearm that houses the operating parts of the gun.

 Multipath diversity spread spectrum receiver - Patent 4291410
The amplifier 4 amplifies the received signal to a sufficient level for processing by the signal detector 7 which is connected to the amplifier 4 by means of conductor 9.
In processing the received signal, the assumptions made on the channel characteristics are: the multipath components are quasi-stationary in time, that is, multipath fading is stationary over each symbol, but is independently Rayleigh fading from symbol to symbol.
Curve 90 is the optimum performance of the receiver in a line of sight operation where there is slow fading over a message interval, and curve 92 is the worst case performance of the receiver under rapid fading from symbol to symbol.

Pertaining to the performance of a computation during the actual time that the related physical process occurs, in order that results of the computation can be used in guiding the physical process.
receive-after-transmit time delay:  The time interval between (a) the instant of keying off the local transmitter to stop transmitting and (b) the instant the local receiver output has increased to 90%  of its steady-state value in response to an rf signal from a distant transmitter.
receiver release-time delay:  The time interval from removal of rf energy at the receiver input until the receiver output is squelched.

There are avenues of attack available to relatively poor, armyless terrorist groups that are both more lethal -- far more lethal -- and harder to defend against than the horrifying crashing of passenger-laden airliners into buildings.
They do not have the kind of radar signature that the military associates with an attack, and it is not difficult to apply some stealth techniques to diminish their radar visibility further.
This time, telemetry told them that all was well and when the GPS indicated that the plane was overhead, human eyes got the first glimpse of it since it had vanished into the air over the North American continent.

The presentation of the attack will be divided into three parts: the ``Established State'' which is the state where the session is open and data is exchanged; the set up (or opening) of such a session; and finally some real examples.
About 10% of the attacks performed were unsuccessful, ending either by a connection close (very visible) or a non-desynchronized connection (the attacker failed to redirect the stream).
The are four principal differences between Morris' attack and the present one: - Morris's relies on the trusted hosts identification scheme whereas the present attack lets the user conduct the identification stage of the connection.

 Concurrent TESLA instances
Receivers with a low network delay welcome short key disclosure delays because that translates into a short authentication delay.
Unfortunately, receivers with a long network delay could not operate with a short disclosure delay because most of the packets will violate the security condition and hence cannot be authenticated.
The reason for generating all different, independent keys for each instance is to prevent an attack where an attacker moves the MAC value of an instance to another instance, which might allow it to claim that data was sent in a different interval.

 The PC Technology Guide
This means that access times must be fast enough to avoid read overrun errors and transmission latency at higher bit rates.
The size of the receiver FIFO ensures that as many as 16 bytes are ready to transfer when the CPU services the UART receiver interrupt.
However, since a time lag in servicing an asynchronous transmitter usually has no penalty, CPU latency is of no concern when transmitting, although ultimate throughput may suffer.

 Optimal Time to Treat Migraine Pain With Relpax(R) is Early in the Attack, New Study Finds
In the study, two-hour and sustained pain-free rates nearly doubled among patients who treated their attack while the pain was still mild compared with those who waited until the pain became moderate to severe.
Among patients who waited to take Relpax 40 mg until the attack became moderate to severe, two-hour pain-free rates were 39 percent (compared with 21 percent taking placebo).
However, among the 25 percent of patients who treated their attack with Relpax 40 mg when the pain was still mild, two-hour pain-free rates jumped to 68 percent (compared with 25 percent taking placebo).

 DoS on the Packet Buffer
Because the scheme only requires the receiver to buffer packets for the duration of one disclosure delay until the authenticity of the packets can be verified, hence the buffer size only needs to be the multiplication of the network bandwidth and the disclosure delay time.
The receiver pre-authenticates the packet by verifying that the disclosed key really is part of the key chain.
If the receiver has too little memory to buffer all incoming traffic during the disclosure delay, it needs to decide on a drop or replacement policy in case of a full buffer.

From the run times provided, it looked like the run times are also dependent on the number of nets with cross-coupling capacitances.
When they do post-route static timing analysis they also calculate the supply drop at each gate and derate the delays individually based on their Synopsys library model (kind of like the Simplex/Silicon Metrics flow), rather than just assuming all gates will have maximum supply drop at worst case conditions.
