#Terralux Battles Commoditization By Integrating Smarts With LEDS For Commercial Lighting Refits LED lighting technology has advanced in leaps and bounds in the last few years.
Less than a decade ago, LEDS were both ineffective and expensive. Not only did they have low output,
Fast forward to today and LEDS have improved greatly in efficacy, now demonstrating some of the highest light outputs,
At the same time, the economics of LEDS are now comparable with other light sources. These changes have resulted in LEDS displacing CFLS as the choice for organizations looking to save money
and deliver an environmentally friendly lighting alternative. But while these huge benefits for LED consumers have come to fruition,
LED TECHNOLOGY rapidly becomes commoditized meaning that LED vendors, once selling into a top-level market, now need to compete with other vendors based on price.

the sensor revolution is well underway. Through the Internet of things (Iot) and the Internet of Everything (Ioe), smart sensors have the potential to significantly help our societies resolve countless global challenges.
In order to do so in a timely manner, major advancements are required in the development of ultra-efficient sensors.

View all Sensors are linked very closely to the Iot, as its core function is to collect valuable data.
Fundamentally, what makes a smart sensor"smart"is its onboard signal/data-processing capabilities. Through the Iot, large amounts of quality, sensor-based data can be collected at any time and from anywhere,
and it can then be transmitted over a network in real time. This provides enhanced awareness of our immediate or remote environment, bringing forth opportunities for faster and better decision-making,
The new generation of ultra-efficient smart sensors requires key characteristics such as small size low cost, low power consumption, low bandwidth consumption,
and high reliability. And this is precisely what Leddar technology has achieved. Based on almost a decade of relentless research, this unique solution breaks the mold for
Leddar Technology Overview Leddar (acronym for light-emitting diode detection and ranging) is patented a sensing technology developed by Leddartech,
The main innovation behind this new approach lies in the superior signal processing that drives every Leddar sensor.
Combined with the use of visible or infrared LEDS to perform time-of-flight measurements,
the Leddar sensor's LEDS and emitter optics are used to create a diffuse beam covering a wider area of interest.
The receiver collects the backscatter of the reflected light from objects in the beam and, using full-waveform analysis,
measuring the distance of the detected objects (based on the time taken by the light to return to the sensor).
and a wide range of optics options are available for the sensor modules, providing a variety of beam patterns for different needs.
or multiple sensors. This unique sensing technology presents multiple advantages. The use of a diffuse light beam increases the detection robustness of specular surfaces.
Aligning the sensor is also easier, which results in fast and simple installation. Additionally, the multi-element receiver provides detection
and ranging for multiple segments of the beam without the need to scan (no moving parts).
Time-of-Flight Principle Leddar sensors use LEDS to generate very short light pulses, typically 100,000 pulses per second.
The time-of-flight (Tof) principle essentially consists in measuring the time taken by a light pulse to travel from the sensor to a remote object
and to return to the sensor. The range R of the detected object is deduced from the measured full round-trip time T of the light pulse using the simple relation R c T/2 n
This causes different irradiances of the echo pulse at the receiver, which are measured by the Leddar sensor.
This measured irradiance depends on the distance measured by the Tof principle and the angle of incidence that can be determined by imaging-collecting optics that focus the reflected beam on the sensor photodetectors.
A 16-element photodetector is used typically in Leddar sensors (shown in Figure 1). Figure 1. Signal travelling through the main components of a Leddar sensing module Figure 1 Signal travelling through the main components
of a Leddar sensing module Beam Pattern for Multi-Element Option The multiple-element photodetector has a rectangular sensing area.
The purpose of the emission optics of a Leddar sensor is to direct as much of the emitted light from one
or more LEDS into a pattern that best fits the photodetector geometry. The purpose of the reception optics is to collect the backscatter of light from objects in that beam onto the photodetector.
Figure 2 illustrates a simulated emission beam pattern of a Leddar sensor with an overlay of the matching segments provided by the reception optics corresponding to the photodetector elements.
The sensor signal is amplified, and the signal acquisition is synchronized to the pulses. An oversampling scheme using multiple light pulses is implemented to improve the resolution of the acquired signal.
in order to improve the signal to noise ratio. The oversampling value and number of accumulations influence the detection/measurement,
The performance of the sensor can thus be optimized with these parameters to meet the requirements of the application.
Detection and Distance Measurement The detection and distance measurement is performed by the sensor's processor,
The signals consist of a series of values representing light amplitude at incremental distances from the sensor.
The amplitude depends on distance, size, reflectivity and angle of the object with respect to the sensor. An object will be detected by the sensor
if a light pulse above a predetermined threshold is found. The threshold at which a peak in the trace is interpreted as the presence of an object depends on the signal-to-noise ratio.
Leddartech determines the default threshold level for each sensor based on the signal-to-noise ratio. A threshold table is applied in the detection processing of the traces,
and a threshold offset parameter is provided on most sensors in order to adjust this threshold table. The offset can be set to increase
or decrease the sensitivity of the sensor. This can be used to ignore the presence of objects returning weak signals
Another setting available on Leddar sensors IS LED the intensity. LED intensity control can be set to manual mode or automatic mode.
In automatic control mode, the sensor will dynamically adjust the LED intensity based on the amplitude of the signal for objects detected in the sensor beam.
With this control, a sensor model can be used for a wide range of applications with different range requirements
and also be used in applications where objects can both be very close or far from the sensor.
In this example, the sensor is collecting light reflected back by two separate objects. Full waveform analysis performed by Leddar sensors provides the capacity to detect multiple objects in the same segment.
This is possible if the closer object is smaller than the illuminated area for that segment.
the multi-element sensor software generates a combined graphical representation of all segments, as shown in Figure 4 below.
this beam contains 16 of the pulses illustrated in Figure 3 Benefits of Leddar Technology Leddar sensors provide three key benefits compared to competing products:
As an optoelectronic technology it can easily be adapted to almost any final application. Of particular benefit to developers and integrators is the technology's unmatched cost/performance ratio,
its ability to detect multiple objects in each segment and lateral discrimination (multi-element platform), its long detection range with low-power LEDS, real-time object-tracking capabilities, detection

providing an ultra-low-power sensor core that can easily fit into a small footprint. Because of their compact size and flexible interfaces
Namely, the included software development kit provides sample code for developers to quickly integrate sensor data into their application software.

#World's highest-performance single-molecule diode created As electronics miniaturization heads towards a theoretical physical limit in the tens of nanometers,
new methods of manufacturing are required to produce transistors, diodes, and other fundamental electronic components. In this vein, a new range of molecule-sized devices have been created in the laboratory,
though with varying results in terms of efficiency and practicality. Now a group of researchers from Berkeley Lab and Columbia University claims to have created the highest-performing,
single-molecule diode ever made, which is said to be 50 times better in performance and efficiency than anything previously produced.
Ordinary diodes are constructed usually from silicon with a p-n (positive-negative) junction created at the point of contact between a positively"doped"semiconductor (that is,
Flanked by connecting electrodes (an anode on one side and a cathode on the other),
the most common function of such a diode is to permit electric current to flow in one direction only,
As such, a diode used in this way can be seen as a type of flow-control valve that is either"on"or"off".
and so these types of diodes are known as rectifiers. This on/off asymmetric behavior in the nascent field of molecule-sized electronics, on the other hand, is achieved usually by the creation of molecules that chemically emulate the p-n junction.
However, these synthesized molecular junctions have resulted generally in poor forward current flow capabilities and inefficient or patchy rectification.
This is where the Columbia university scientists claim to have made significant improvements with their new single-molecule diode."
"Using a single symmetric molecule, an ionic solution and two gold electrodes of dramatically different exposed surface areas,
we were able to create a diode that resulted in a rectification ratio, the ratio of forward to reverse current at fixed voltage, in excess of 200,
"The asymmetry necessary for diode behavior originates with the different exposed electrode areas and the ionic solution.
This leads to different electrostatic environments surrounding the two electrodes and superlative single-molecule device behavior."
particularly as diodes form the basis of many microminiature electronic devices. Since then, a range of devices have been constructed,
including single molecule diodes and transistors. Operating at this nanoscale, though, such devices may emulate their macro counterparts,
"said professor"The efficiency of the tunneling process depends intimately on the degree of alignment of the molecule discrete energy levels with the electrode continuous spectrum.
and Zhenfei Liu to understand the diode behavior quantitatively.""Zhenfei Liu a postdoctoral fellow at Berkeley Lab and professor Neaton worked with Latha Venkataraman
and Luis Campos from Columbia University to create their high-performance rectifier diode using junctions prepared from symmetric molecules attached to gold electrodes.
To achieve the necessary asymmetric properties required to operate as a diode, the researchers then altered the surface area of the electrodes as they were exposed to an ionic solution.
As a result, a positive voltage increased the current significantly, whilst a negative voltage reduced current flow in an equally significant manner."
"The ionic solution, combined with the asymmetry in electrode areas, allows us to control the junction electrostatic environment simply by changing the bias polarity,
"In addition to breaking symmetry, double layers formed by ionic solution also generate dipole differences at the two electrodes,
The Columbia group experiments showed that with the same molecule and electrode setup, a nonionic solution yields no rectification at all."
"The combined Berkeley Lab-Columbia University research team is convinced that the way they have managed to produce a single-molecule diode sets the benchmark for future nonlinear nanoscale device tuning and development, with applications above and beyond just
