#Wearable Technology Combines Inertial and Electromyographic Sensors for Detecting Gestures A smart device that translates sign language
The wearable technology combines motion sensors and the measurement of electrical activity generated by muscles to interpret hand gestures,
notes Jafari who presented his research at the Institute of Electrical and Electronics Engineers (IEEE) 12th Annual Body Sensor Networks Conference this past June.
Jafari system makes use of two distinct sensors. The first is an inertial sensor that responds to motion.
Consisting of an accelerometer and gyroscope the sensor measures the accelerations and angular velocities of the hand and arm, Jafari notes.
This sensor plays a major role in discriminating different signs by capturing the user hand orientations and hand and arm movements during a gesture.
However, a motion sensor alone wasn enough, Jafari explains. Certain signs in American sign language are similar in terms of the gestures required to convey the word.
With these gestures the overall movement of the hand may be the same for two different signs,
Jafari system makes use of another type of sensor that measures muscle activity. Known as an electromyographic sensor (semg), this sensor non-invasively measures the electrical potential of muscle activities,
Jafari explains. It is used to distinguish various hand and finger movements based on different muscle activities.
Essentially, it good at measuring finger movements and the muscle activity patterns for the hand and arm, working in tandem with the motion sensor to provide a more accurate interpretation of the gesture being signed,
In Jafari system both inertial sensors and electromyographic sensors are placed on the right wrist of the user where they detect gestures
and expanding the system to both hands. he combination of muscle activation detection with motion sensors is a new and exciting way of understanding human intent with other applications in addition to enhanced SLR systems,

For power, these new sensors rely on the reader. Specifically, there a metal coil inside the reader and a much smaller coil in the sensor itself.

#Overview of a Smart Optical Time-of-Flight Sensor Technology With billions of sensors already being deployed in all types of devices and applications,
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.
Figure 1. Signal travelling through the main components of a Leddar sensing modulefigure 2. Emission beam pattern and match to a 16-element photodetectorfigure 3. Sample trace
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,
The main innovation behind this new approach lies in the superior signal processing that drives every Leddar sensor.
the Leddar sensor's LEDS and emitter optics are used to create a diffuse beam covering a wider area of interest.
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
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
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
The purpose of the emission optics of a Leddar sensor is to direct as much of the emitted light from one
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.
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:
