The realisation of the Timepix3 chip opened way for new opportunities in research areas such as particle tracking with both semiconductor sensors and gas filled time projection chambers, electron microscopy imaging mass spectrometry.
The SPIDR (Speedy PIxel Detector Readout) system is a flexible general-purpose readout platform that can be easily adapted to test and characterize new existing detector ASICs. It originally designed for the of pixel ASICs from Medipix/Timepix family, but other types or front-end circuits read out as well. consists an FPGA board with memory various communication interfaces, firmware, CPU subsystem API library on PC . firmware by re-using IP blocks. available blocks include UDP packet...
Electrowetting displays combine bright reflective colors and low-power consumption enabling to be used in office environments as well outdoor sunlight. This paper reports on gray scale generation an active matrix display with a resolution of 170 ppi. We present the results for both pulse width modulation (PWM) amplitude (AM). Using limited number scales very large range brightness levels is obtained due scaling ambient light intensity.
We present the use of electrowetting as a technology for very bright and energy-efficient displays. The intrinsic nature system an optical switch provides excellent starting point upon which wide variety display configurations can be based. Here we focus our discussion on reflective displays, in main advantages are best utilized. properties will discussed, illustrating combination paper-like performance video-speed switching.
An iterative bias estimation framework is presented that mitigates position-dependent ranging errors often present in ultra-wideband localization systems. State and control are integrated, such the positioning accuracy improves over iterations. The experimentally evaluated on a quadcopter platform, resulting improvements tracking performance with respect to ground truth, also smoothing overall flight by significantly reducing unwanted oscillations; see https://youtu.be/J-htfbzf40U for video.
The LHCb VELO Timepix3 telescope is a silicon pixel tracking system constructed initially to evaluate the performance of Upgrade prototypes. consists eight hybrid sensor planes equipped with ASIC . provide excellent charge measurement, timestamping and spatial resolution can function at high track rates.

In 2000, the requirements for a large TPC experiments at new linear collider were formulated. Both GEM and Micromegas gas amplification systems had matured, such that they could be practically applied. With Medipix chip, pixel-segmented anode readout became possible, offering an unprecedented level of granularity sensitivity. The single electron sensitive device is digital detector capable to record transfer all information primary ionization, provided it can made discharge proof.
Sim2real, that is, the transfer of learned control policies from simulation to real world, is an area growing interest in robotics due its potential efficiently handle complex tasks. The sim2real approach faces challenges mismatches between and reality. These discrepancies arise inaccuracies modeling physical phenomena asynchronous control, among other factors. To this end, we introduce EAGERx, a framework with unified software pipeline for both simulated robot learning. It can support...

The Timepix detector can be operated in Time-over-Threshold mode to allow for charge integration measurements as required by short (< 50 fs) x-ray pulses of the Linac Coherent Light Source (LCLS). Initial commissioning activities have started at X-ray Correlation Spectroscopy (XCS) instrument LCLS, where speckle patterns been measured.
Abstract The spatial and temporal performance of a four-plane system composed silicon sensors bump-bonded to Timepix4 ASICs is assessed with 180 GeV/c mixed hadron beam at the CERN SPS reported in detail. Particle tracks are reconstructed using time-space measurements from four detector planes, two 100 μm planes perpendicular 300 under an angle 9°. hit resolution be (15.5 ± 0.5) (4.5 0.3) for thick sensors, respectively. timestamps detectors also measured fine precision, yielding time...
The up-and-coming concept of Industry 5.0 fore-sees human-centric flexible production lines, where collaborative robots support human workforce. In order to allow a seamless collaboration between intelligent and workers, designing solutions for non-expert users is crucial. Learning from demonstration emerged as the enabling approach address such problem. However, more focus should be put on finding safe which optimize cost associated with demonstrations collection process. This paper...
