Synthetic Aperture Radar (SAR) with active phased array antenna is a system having distributed controllers for control and synchronization of individual RF elements. In current generation SAR payloads of ISRO, three level of distributed control hierarchy is adopted. Transmit/Receive controllers (TRC), as a separate subsystem comes at the third level of hierarchy. TRC loads attenuation and phase digital data to each RF element (T/R module) for electronic beam steering. Phased array radar systems consist of hundreds of such subsystems. In new space arena, requirement of low weight and miniaturized volume SAR payload necessitates the reduction of subsystems and interconnect lines. An innovative approach is adopted through partitioning the task in such a way that TRC as a subsystem shrinks into a single IC solution named as Serialized control interface (SCI) ASIC. SCI ASIC can be housed inside TR Module as a component thus omitting the need of TRC as a separate subsystem. Traditionally, telecommand, telemetry and radar timing signals are communicated through separate differential inter-connect lines between central controller and distributed controllers. Bulky interconnect lines increase complexity, size and weight of payload. With new approach of SCI ASIC, harness complexity is significantly reduced due to signal generation inside SCI through pattern generator concept. We present architecture, design and implementation methodology for SCI ASIC which controls TR Modules to meet all the functional requirements of advanced imaging RADAR.

Traditional methods of monitoring vital signs in vehicles often fall short when it comes to response time, especially in fast-moving situations. To tackle this, our paper introduces a groundbreaking solution: leveraging millimeter-wave radar technology to monitor vital signs in real time within the vehicle, providing timely alerts when necessary. This approach not only enhances the accuracy of readings but also ensures a swift response that is crucial during vehicle operation. By tapping into the unique abilities of millimeter-wave radar to detect subtle human signs, we propose a novel method that processes radar signals to monitor vital signs like heart rate and respiratory rate. This technique is highly effective in meeting the stringent demands of real-time accuracy and speed, especially while driving. Our system includes three main components: radar sensors, a signal processing unit, and an early-warning control module, working together seamlessly to ensure optimal monitoring. The radar sensor continuously transmits and receives millimeter-wave signals, allowing it to track vital signs without interruption. A specially designed feature extraction algorithm filters out noise and extracts critical information, including heart and respiratory rates. Then, advanced algorithms analyze this data in real time, spotting any abnormalities and triggering alerts through the control module. What sets this system apart is its rigorous testing under various vehicle speeds and environmental conditions, confirming its stability, reliability, and fast response times. In real-world applications, the system responds to a high heart rate in 3.7 to 4.0 seconds and to a rapid breathing rate in 4.1 to 4.3 seconds. This millimeter-wave radar-based system offers a fresh approach to vehicle safety, combining practicality with promising future potential.

Increased flight time and advanced sensors are making Micro Aerial Vehicles (MAVs) easier to use, facilitating their widespread adoption in fields such as precision agriculture or environmental monitoring. However, current applications are limited mainly to passive visual observation from far above; to enable the next generation of aerial robot applications, MAV s must begin to directly physically interact with objects in the environment, such as placing and collecting sensors. Enabling these applications for a wide spectrum of end-users is only possible if the mechanism is safe and easy to use, without overburdening the user with complex integration, complicated control, or overwhelming and convoluted feedback. To this end we propose a self-sufficient passive payload system to enable both the deployment and retrieval of sensors for agriculture. This mechanism can be simply mechanically attached to a commercial, off-the-shelf MAV, without requiring further electrical or software integration. The user-centric design and mechanical intelligence of the system facilitates ease of use through simplified control with targeted perceptual feedback. The usability of the system is validated quantitatively and qualitatively in a user study demonstrating sensor deployment and collection. All participants were able to deploy and collect at least four sensors both within 10 minutes in visual line-of-sight and within 12 minutes in beyond visualline-of-sight, after only three minutes of practice. Enabling MAVs to physically interact with their environment will usher in the next stage of MAV utility and applications. Complex tasks, such as sensor deployment and retrieval, can be realized relatively simply, by relying on a mechanically passive system designed with the user in mind, these payloads can enable such applications to be more widely available and inclusive to end-users.

Electromyography (EMG) sensors have been widely used for assessing muscle activation state and human-robot interaction (HRI). However, available commercial EMG sensors are expensive and inconvenient for real-time applications. The aim of this study is to design and validate a novel low-cost wireless EMG sensor. Specifically, the wireless EMG sensor is equipped with an analog-front-end (AFE), radio frequency (RF) module, and controller area network (CAN) bus, which achieves wireless data transmission and provides an interface for real-time HRI. The evaluation of the designed system was done by a series of exercises performed by volunteers. Raw signal., mean absolute value (MAV), zero crossings (ZC), slope sign changes (SSC), waveform length (WL), and median frequency (MDF) are used for comparing wireless EMG sensors and commercial sensors. In addition, Spearman's correlation (SC), and intra-class cross-correlation (ICC) are used as two validation indicators. The result shows that the SC and ICC between the raw signals of the two types of sensors are 0.6156 and 0.7780, respectively. The SC of MAV, ZC, SSC, WL, and MDF are 0.9708, 0.6740, 0.8023, 0.9663, and 0.9476, respectively. The ICC of MAV, ZC, SSC, WL, and MDF are 0.9670, 0.7340, 0.7910, 0.9540., and 0.8230, respectively. The results indicate a good agreement between the two systems and confirm the reliability of the wireless EMG sensor's design. The wireless EMG sensor can be further applied to real-time HRI and muscle fatigue assessment.

This paper focuses on the interoperability of smart devices (sensor and actuators) in the context of the Industrial Internet of Things. IEC 61499 and IEEE 1451 standards are employed to implement a distributed control and measurement system. It addresses how two standards can interoperate and communicate efficiently by complementing each other. Both standards share common properties which are the essential elements of any IoT system. The Message Queue Telemetry Protocols (MQTT) is utilized to provide an interoperable network interface between the IEEE 1451 family of standards and the IEC 61499 standard. An interoperability test platform is provided to show how both standards communicate efficiently for a simple read/ write automation process.

This paper introduces a low-cost assistive device to improve the quality of life of individuals with Motor Neuron Disease (MND) using a Brain-Computer interface (BCI). The proposed device allows MND patients to communicate with their environment and execute instructions using a Graphical User interface (GUI) that translates Electroencephalogram (EEG) signals into computer input. The GUI presents a cube as a visual cue and a set of instructions or operations, enabling the user to control different Internet of Things (IoT) devices. The user may toggle through the instructions by thinking of pulling the cube and may select an instruction by thinking of making the cube disappear. To adapt the system to a real-world scenario, we use a type of transfer learning called domain adaptation. We further investigate by generating four real-world datasets and using five different machine learning schemes, including four domain adaptation strategies. Our experiments show that four out of five learning strategies perform satisfactorily.

This paper presents the design and implementation of an intelligent radiator system that leverages Internet of Things (IoT) technology and hand gesture recognition (HGR) to enhance thermal management and energy efficiency in residential environments. The system addresses the limitations of traditional heating systems by enabling users to control radiator temperature via a web interface and intuitive hand gestures. The system utilises a Raspberry Pi, an ESP32, and sensors (temperature, ultrasonic, and gyroscope sensors) to monitor the environment and enable precise control. The HGR functionality, powered by MediaPipe, allows for convenient, touchless adjustment of heating settings with an accuracy of 73.02%. The system’s performance is evaluated through a LEGO prototype, and potential refinements, such as dataset expansion and model optimisation, are discussed. The project demonstrates the potential of IoT technology to deliver innovative and practical solutions for energy management in smart homes. Future work envisions the integration of the system with a mobile robotic platform, enabling dynamic thermal data collection, enhanced human-robot interaction, and expanded home automation capabilities.
