Drones have been used by criminals to smuggle cell phones and drugs into prisons. They also may cause accidents in airports other heavy flight traffic zones, so it is clear that interesting take control of drones some specific situations. This work part a project intended develop system (hardware software) the law-breaking drones. uses an embedded Linux board communicating via SPI with radio IC emulate controllers signal, admitting several parameters: raw, pitch, yaw roll. In addition, this...
Abstract In synchrotron light source applications, the photon beam interaction with various materials can produce electric charge which be measured as current and used to diagnose particle trajectories, intensity, profile, position, stability. Sirius, a 4th-generation Brazilian source, will make use of hundreds low-intensity measurement instruments. This work aims show discuss design details, challenges, test results an Ethernet four-channel high-performance digital ammeter, applied for...
High-energy photon imaging experiments are crucial techniques in synchrotron facilities, often employing hybrid pixel detectors for these operations. These combine a photo-sensitive semiconductor component with pixelated microelectronic Application Specific Integrated Circuit (ASIC) signal processing and image formation. However, detecting photons above 90 keV poses significant challenges, even heavy semiconductors, due to lower photoelectric absorption cross-section at this energy range....
Abstract TUPI (Timepix4-based Ultra-fast Photon Imaging) is the new family of direct conversion and vacuum-compatible hybrid detectors under design at Sirius, Brazilian 4th generation light source. Based on Timepix4 Application Specific Integrated Circuit (ASIC), it targets different kinds experiments, such as tomography spectrometry, will be used in multiple bioimaging beamlines Orion, Brazil's Biosafety Level 4 (BSL4) Laboratory project. Also, cover a wide energy range (5 to 45 keV) by...
Nowadays, with the technological evolution, use of wireless identification devices is growing up. RFIDs tags are being used to track a product through an assembly line, packaged goods, animals and even humans. The system proposed on this paper intends identify whether passive tag goes in or out reader area. device composed by linear antenna, tuned amplifier VSWR meter, fully integrated Printed Circuit Board (PCB). receives 400MHz signal, filtering all frequencies desired range, amplifies...
A dual band vivaldi antenna was designed to operate at the frequencies of 2.4GHz and 5.8GHz, which are common used by drones' radiocontrollers.The project idea is use this simulated as an upgrade for a previously created spoofing module [1], that consists in system responsible identifying drone's radiocontroller signal range (as well checking its model) then emitting own capable taking control drone.
Abstract TARUMÃ is a multi-technique station at CARNAÚBA (Coherent X-Ray Nanoprobe Beamline) the 4th-generation light source Sirius Brazilian Synchrotron Light Laboratory (LNLS). With tender-to-hard energy range from 2.05 to 15 keV and fully coherent nanoprobe focused via an all-achromatic KB (Kirkpatrick-Baez) optics, it can be used for simultaneous multiple nanoscale X-ray techniques in 2D 3D. This includes ptychography diffraction imaging (ptycho-CDI), absorption spectroscopy (XAS),...
The proposed device is a smart wireless sensor that can establish an auto-adaptive mesh network and concentrate all devices information in data center.Each has current sensor, designed to identify whether lamp turned on or off.A microcontroller receives the state delivers it module (NRF24L01), responsible communicate with others devices.The system allows verifying, realtime, each light spot's save operational log.
