What does the term efficient mean?
if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes
Why 40 angle of attack during reentry of spaceshuttle?
An angle of attach of less than 40 degrees would have caused the shuttle to bounce back off the atmosphere - in the same way as stones are skimmed on water.An angle greater than 40 degrees would have resulted in great deal of drag (friction). This would have caused the shuttle's skin to heat up more than the heat-tiles could have managed.An angle of attach of less than 40 degrees would have caused the shuttle to bounce back off the atmosphere - in the same way as stones are skimmed on water.An angle greater than 40 degrees would have resulted in great deal of drag (friction).

What is a steel rule and what is it used for?
The steel rule is a measuring device. It is used to measure a piece of work such as engineering and is usually used just as if it were nothing more than a regular ruler.
What are the advantages of micrometer?
A micrometer (device) measures distance more accurately with more precision than a vernier or a tape measure. It is much cheaper than using an electron microscope, which can measure, with calibration, a length in the order of 1E-9 meter. A micrometer (unit) is equal to 1E-6 meter.
Was math in WW2?
Math was definitly in WW2. Half of the devices and machines required math. For example, a radar may look like nothing more than a device that pin points enemy locations. However, inside of that device, it gives you distance, degrees and some other mathematical procedures.
Can a tv be hacked into a transmitter rather than a receiver?
yes . electronically it is possible to convert a tv reciver into a crude very low power transmitter. however if one has the knowledge to do the conversion, it will be far more simpler to attach a transmitter device to the video player or camera rather than using a small section of the TV set as a transmitter
What is a Neutroni Transmitter and how does it work?
The Possibility exists this is a science-fiction device akin to the Sub-Space radio used on The televisin program Star Trek. The device (Neutroni ) was something akin to a long range but somewhat clandestine (SSB?) radiophone system. the device was(More than Plausible)
How is the transmitter of a cellular telephone different from a powerful radio transmitter?
A radio plays music, and is not a phone. A telephone is used for talking between two persons.
Why battery life of a pager is better than a cellphone?
Because a pager is just a radio receiver and not a radio transmitter. A cell phone is both a receiver and a transmitter. A receiver uses much less battery power than a transmitter does. And because a pager's disposable alkaline battery holds more power than a cell phone's rechargeable battery.
How powerful is a 980nm IR Light Amplification by Stimulated Electronic Radiation Device?
The wavelength of the radiation coming out of that laser doesn't tell you its power level, any more than the spot on your radio dial tells you the transmitter power of the radio station you hear there.
A device having more than one IP address is known as device?
Multi-homed device.
How does wireless remote control for crane works?
Radio remote control: The wireless equipment or machines works on radio waves technology. The artificial radio wave is generated to control the electronic machine such as the overhead crane is called radio remote control. The overhead crane is used for industrial purposes which move and travels above the head at a particular height. The device can move the EOT crane in different directions like cross travel, long travel, and hoist. The hoist is used for lifting and lowering heavy objects. The transmitter and receiver are the two main components that are used for sending and receiving the signal for communication. The radio transmitter has various types such as 8 button radio remote, 12 button radio remote, and joystick radio remote control devices. These all types of devices have their features and specifications. Principle of wireless remote control for crane: The transmitter and receiver are used for communication to control the machines. The transmitter is a handy and small device that can be easily carried by one hand. The operator uses the transmitter device while the receiver is attached to the overhead crane. Communication happens between the transmitter and receiver when the transmitter sends the signal. Whenever the operator pushes the button on the transmitter device a data-packed is sent to the receiver in an encryption form. That means data is first converted to the cipher text from the plain text. When the signal reaches the receiver first decodes the data, the data is converted from cipher text to plain text. This encryption technique is used for the safety of data packets and the communication is not affected by the external entity. More than 10 times in a second communication happens between the transmitter and receiver. And the transmitter device can range from 10 meters to 200 meters distance for communication. While communicating with the receiver the transmitter device detects many things like how many data packets are sent, the communication, the speed of communication, the loss of data packets, successful transmission, number of errors, the signal quality, the distance, and many more. The hopping method is followed by the transmitter and receiver to circumvent unnecessary interference. The EOT crane remote control device provides the interlocked systems in a pair while in use. That means two buttons in a pair cannot be used at the same time. If an up button is pressed on the transmitter device at that time down button cannot be pressed. And we have to keep pressing the up button until the overhead reaches its destination. Features of overhead crane remote control systems: The radio remote control can range from 10 meters to 200 meters. The device uses the 2.4 GHz frequency band technology. The transmitter device is made in such a way that it prevents corrosion and shock. More than 10 times in a second communication happens between the transmitter and receiver. The communication can range from 10 meters to 200 meters. The transmitter device is highly optimized and customized while in use. The crane remote control coating is so strong that it can be used for harsh industrial conditions. The transmitter is a wireless device and works on the battery or charging systems. The remote control adjusts the power automatically according to the distance. The transmitter device works well at a very low battery also. Precedence of crane remote control: The main advantage of the crane remote control system is that it works on the battery or charging replacement system and hence the overhead crane can be operated from a long distance also. And the operator doesn't have to sit inside the crane which makes risk free. The battery used in the transmitter device is durable and can last long up to 6 months. The communication is very safe and secure between the transmitter and receiver. The communication happens rapidly i.e. 10 times in a second. The transmitter uses wireless technology for communication and if any error or lag is found in the systems then the transmitter stops working immediately. According to the distance, the power is automatically adjusted by the transmitter device. That means if the distance is less between the transmitter and receiver then less power is consumed by the device. And if the distance is far then the power is adjusted according to the distance.
What is the transmitting range of 10kw FM transmitter?
As FM is transmitted using VHF, the transmitting range is more a matter of Line of Sight than transmitter power as these frequencies only follow straight lines.
What is a duplexer?
A duplexer is a device that allows bi-directional (duplex) communication over a single channel. In radar systems, a device that isolates the receiver from the transmitter while permitting them to share a common antenna. Note 1: A duplexer must be designed for operation in the frequency band used by the receiver and transmitter, and must be capable of handling the output power of the transmitter. Note 2: A duplexer must provide adequate rejection of transmitter noise occurring at the receive frequency, and must be designed to operate at, or less than, the frequency separation between the transmitter and receiver. Note 3: A duplexer must provide sufficient isolation to prevent receiver desensitization.Braimah prosper
Did Thomas Edison invent anything other than light?
Yes he did make more than just light. Here are some of the others: Telegraph transmitter| Video| and lots more
How do you create transmitter?
we can create transmitter by using modulator circuit depending what frequency range you would like to use if you want to use FM range 88 to 108 MHz than you may refer to FM modulators and if you are going to more than 300MHz than you will need RF receiver.
Why pager has better battery life?
Because a pager is just a radio receiver and not a radio transmitter. A cell phone or a cordless phone are both a receiver and a transmitter. A receiver uses much less battery power than a transmitter does. And because a pager's disposable alkaline battery holds more power than a cell phone or cordless phone's rechargeable battery.
