Peak-to-Average Power Ratio (PAPR) Reduction for High-Speed Communications
Description and Need Modern data communication demands ever-increasing transmission rates, with current standards targeting 100 Gbps to 400 Gbps. As symbol rates rise, intersymbol interference (ISI) causes the Peak-to-Average Power Ratio (PAPR) at the receiver to increase significantly, sometimes exceeding 10 dB. High PAPR requires receivers with a large dynamic range, leading to higher circuit […] Read More >
DifuzCam: Replacing Camera Lens with a Mask and a Diffusion Model
DifuzCam represents a novel approach of flat lensless camera imaging. By eliminating traditional lenses and instead using a diffuser near the sensor, the camera size, weight and cost are drastically reduced. However, reconstructing high-quality images from the raw sensor data of such cameras is an ongoing challenge. Our invention proposes a solution by leveraging a […] Read More >
Calibration of Fiber Optic Sensor Underground
The precise geolocation of underground fiber optic telecom cables is crucial for operator maintenance, to avoid construction-related damage, and to minimize costs during network upgrades. Our innovative calibration technology provides non-instrusive high-accuracy localization of subsurface fiber optic cables, using only video inputs and ambient urban under any noise conditions. In addition, the same data are […] Read More >
Traffic Monitoring Using Fiber Optic Sensor
The rapid development of smart cities and their infrastructure requires innovative solutions for traffic monitoring. Fiber optic sensors offer a high-precision, reliable, anonymous, and cost-effective method for real-time traffic data acquisition and analysis. We have developed an AI-based technology, using fiber-optic sensors for comprehensive traffic monitoring systems, enhancing traffic management and safety. UNMET NEED Current […] Read More >
A Fully Integrated Chip Scale Dielectric Resonance Antenna
Due to limited voltage supplies in scaled CMOS and the lower amplitude of harmonic generation at frequencies above transistors’ fmax, the radiated power out of a single element around 300GHz is limited to 0.5mW. Generating more power by combining signals from several locked sources on chip to the same on-chip antenna is not efficient due […] Read More >
Passive communications with time-varying metamaterials
The coming years will see a revolution by connecting everything to anyone, and RFID and similar technologies, will lead this 300B$ USD industry and 50B connected devices. Examining existing RFID standards suggests that the leading standard, called EPC Gen 2, is a standard in the 900MHz frequency which allows hundreds of tags to be read […] Read More >
A Software Only Anti-Spoofing Defense System for In-Car CAN Bus Networks
Modern cars have multiple dedicated computers under the hood called “electronic control units” (ECUs). These ECUs control many aspects of the car’s operation and are connected to each other in a network that typically uses the CAN bus protocol, which bus is a serial protocol with no security components. Replacing CAN bus with another technology […] Read More >
Diffractive Optics based on metamaterials
A new technology for producing flat optical components based on optical metasurfaces. These components can potentially serve high resolution imaging, spectrometry, light processing and beam shaping devices. The optical metasurfaces that we develop are composed of closely spaced optical nanoantennas which can be deposited on a wide variety of rigid and flexible surfaces. The engineered nanoantennas […] Read More >
