Sensor Technology News: Researchers create temperature sensor that runs on almost no power by Mallory Locklear

Researchers at UC San Diego have developed a temperature sensor that runs on tiny amounts of power -- just 113 picowatts, around 10 billion times less power than a watt. The sensor was described in a study recently published in Scientific Reports. "We're building systems that have such low power requirements that they could potentially run for years on just a tiny battery," Hui Wang, an author of the study, said in a statement.

The team created the device by reducing power in two areas. The first was the current source. To do that, they made use of a phenomenon that many researchers in their field are actually trying to get rid of. Transistors often have a gate with which they can stop the flow of electrons in a circuit, but transistors keep getting tinier and tinier. The smaller they get, the thinner the gate material becomes and electrons start to leak through it -- a problem called "gate leakage." Here, the leaked electrons are what's powering the sensor. "Many researchers are trying to get rid of leakage current, but we are exploiting it to build an ultra-low power current source," said Hui.

Romulo Camargo is a U.S. Army veteran who was paralyzed below the neck during an ambush in Afghanistan. Unable to perform everyday tasks for himself, he’s recently received a little help from a robot.

As The Verge notes, Toyota’s Human Support Robot has already been tested in hospitals in Japan, where the company plans to build and sell machines to help care for an aging population. But Camargo is the first person in North America to have one of the firm’s devices roam about his private home, which is a challenging environment for a robot tasked with handling everyday objects.

The robot itself is beckoned by Camargo, who taps a stylus held in his mouth on the screen of a tablet. Then the robot will, say, bring him a bottle of water and raise it so that he can drink from it. “Those are the most important tasks I do throughout the day, and the robot will do it for me,” says Camargo. “You know, that’s something huge.”.

Blinking an LED Circuit Using Relays

Electronic Kit School. - This is one way to result the blinking LED light with simple circuit and only need simple and few component like resistors, capacitor, and relays. 

In here we will show you one of the simple blinking an LED circuit using relays as the main component that switch on and off of LED when controlled with resistors and capacitors. The circuit mentioned look like shown in Figure 1 below.

In this time, beside we will show you the circuit, here we also will show you component part and global description about this circuit.

Circuit 

  1. Relay
  2. Capacitor
  3. Resistors
  4. Battery
  5. LED
Description

Circuit like in Figure 1 above show you about the simple blinking an LED circuit using relays. From BuildElectronicCircuits site describe that when you apply power to the above circuit, the battery starts charging the capacitor through resistor R2. After a moment, the relay coil pulls the relay into the other position.

This makes the LED turn ON. Because the capacitor now is charged, it will hold the relay in this position. But the capacitor only has enough energy to keep the electromagnet in the relay powered for a little bit before it’s empty (or discharged).

When the capacitor is out of energy, the relay goes back into its original state and turns the LED OFF again. Then the cycle repeats itself. For this circuit with the above component values I recommend the DS2Y-S-DC5V relay or a similar one.

This article will show you the reviewing of Fundamentals of WiMAX: Understanding Broadband Wireless Networking like book description. The last in this article we also will give you link to take download e-book of Fundamentals of WiMAX: Understanding Broadband Wireless Networking that authored by Jeffrey G. Andrews.

Overview

From Gen.lib.rus.ec describe that this is the eBook version of the printed book. Praise for Fundamentals of WiMAX "This book is one of the most comprehensive books I have reviewed ... it is a must-read for engineers and students planning to remain current or who plan to pursue a career in telecommunications. I have reviewed other publications on WiMAX and have been disappointed. This book is refreshing in that it is clear that the authors have the in-depth technical knowledge and communications skills to deliver a logically laid out publication that has substance to it." –Ron Resnick, President, WiMAX Forum "This is the first book with a great introductory treatment of WiMAX technology. It should be essential reading for all engineers involved in WiMAX. The high-level overview is very useful for those with non-technical background. The introductory sections for OFDM and MIMO technologies are very useful for those with implementation background and some knowledge of communication theory. The chapters covering physical and MAC layers are at the appropriate level of detail. In short, I recommend this book to systems engineers and designers at different layers of the protocol, deployment engineers, and even students who are interested in practical applications of communication theory." –Siavash M. Alamouti, Chief Technology Officer, Mobility Group, Intel "This is a very well-written, easy-to-follow, and comprehensive treatment of WiMAX. It should be of great interest." –Dr. Reinaldo Valenzuela, Director of Wireless Research, Bell Labs "Fundamentals of WiMAX is a comprehensive guide to WiMAX from both industry and academic viewpoints, which is an unusual accomplishment. I recommend it to anyone who is curious about this exciting new standard." –Dr. Teresa Meng, Professor, Stanford University, Founder and Director, Atheros Communications "Andrews, Ghosh, and Muhamed have provided a clear, concise, and well-written text on 802.16e/WiMAX. The book provides both the breadth and depth to make sense of the highly complicated 802.16e standard. I would recommend this book to both development engineers and technical managers who want an understating of WiMAX and insight into 4G modems in general." –Paul Struhsaker, VP of Engineering, Chipset platforms, Motorola Mobile Device Business Unit, former vice chair of IEEE 802.16 working group "Fundamentals of WiMAX is written in an easy-to-understand tutorial fashion. The chapter on multiple antenna techniques is a very clear summary of this important technology and nicely organizes the vast number of different proposed techniques into a simple-to-understand framework." –Dr. Ender Ayanoglu, Professor, University of California, Irvine, Editor-in-Chief, IEEE Transactions on Communications "Fundamentals of WiMAX is a comprehensive examination of the 802.16/WiMAX standard and discusses how to design, develop, and deploy equipment for this wireless communication standard. It provides both insightful overviews for those wanting to know what WiMAX is about and comprehensive, in-depth chapters on technical details of the standard, including the coding and modulation, signal processing methods, Multiple-Input Multiple-Output (MIMO) channels, medium access control, mobility issues, link-layer performance, and system-level performance.

Description

Circuit like in Figure 1 above show you about the microphone amplifier using the main component Cm and transistors. From Electronicsproject site describe that the circuit diagram you can see that microphone is employs as the transducer. The output of the condenser microphone is quite low it has to connect with an FET amplifier. This amplifier circuit is power by the R1,R2 resistor network. The output of condenser microphone is fed to a two-stage amplifier. Transistor T1 (BC149C) utilise current series feedback the first stage. The second stage comprising transistor T2 is connected in the voltage shunt feedback configuration. These two stages provide sufficient gain to pick up even the slightest whisper. The amplifier circuit in the site requires  4.2 volt supply which can be obtained with a resistor R9 [1k]. 

The value of this resistor may be altered to suit a supply voltage other than 6 volts. Output of the microphone amplifier can be made variable by connecting a 10k potentiometer as shown in the circuit. Circuit‘s gain can be increased by reducing the value of R6 to 47 ohms or 22 ohms. depending on the input sensitivity of the main amplifier system. Increase in gain was also observed by using 3V supply and eliminating R9 altogether. The microphone should be housed in a small round enclosure.
