The COVID-19 pandemic has significantly accelerated the demand for multiple displays in the context of remote working and learning. One critical concern in laptop utilizing USB-C displays is their ...responsiveness. The link training establishes the physical link (4/2/1) and its parameters used for transmission of video and audio over the DP (Display Port) main link. The display driver, responsible for supporting various DP adapters, previously incorporated a static auxiliary retries during clock recovery, which impacted the detection of aux process. Additionally, the internal dependency of the display driver on resetting other enabled displays resulted in prolonged setup time for newly connected displays. Consequently, these factors contributed to increased End-to-End (E2E) latency for Type C displays operating in DP Alternate mode and USB4/Thunderbolt TM Tunnel mode. In this paper we present the approach to optimizing the E2E latency for type C display. We also present optimizations pursued and associated learnings for better user experience (UX). We show optimization results which measurably improves responsiveness.
The increasing use of USB drives as a means of transferring data has led to an increase in malware and ransomware threats, making it crucial to detect and prevent such threats. This research paper ...proposes a solution that utilizes YARA string analysis for USB drives, in combination with Raspberry Pi hardware, to automatically detect and prevent malware and ransomware threats. The proposed solution involves the development of a YARA rule set to identify malicious files, which is then implemented on a Raspberry Pi device to scan USB drives automatically. The results of the study show that the proposed solution is effective in detecting and preventing malware and ransomware threats, with a high degree of accuracy and efficiency. This research presents a practical approach for mitigating the risks associated with malware and ransomware threats on USB drives and provides a foundation for future research in this area.
In this work, a versatile, low-cost, and portable measurement system for thermal and electrical characterization of integrated circuits is presented. The system is based on a reconfigurable testing ...board controlled through a micro-controller which handles the analog and digital signals required for measurements and manages the communication between the testing board and a personal computer (used to control the system, store and process measured data) through the USB interface. The main advantages of the proposed system are the versatility in the generation of the required digital signals (provided by an FPGA which can be customized for any device under test (DUT)) together with the possibility to perform temperature characterization by using a temperature regulator based on a Peltier cell which is integrated and controlled by the measurement system. The DUT is supplied with the required bias and control analog signals generated by the system and can be measured by means of analog and digital acquisition channels. A large number of programmable analog voltages and currents are available, which allows test routines to be easily implemented and applied to the DUT. Finally, the smart graphic interface and the use of programming languages such as C++ or Visual Basic simplify the test flow and the subsequent data processing, thus allowing fast and efficient device characterization. Some examples of electrical and thermal characterization are provided to evaluate the performance and the effectiveness of the proposed environment.
In this paper, an electronic piano performance system is given. Within the system, a traditional piano keyboard is retained, and a micro-controller unit (MCU) C8051F340 is applied to scan the key ...value, velocity of the keyboard and send the scanned data to principal computer (PC) via universal serial bus (USB) interface. In addition, application software for PC has been developed to simulate the sound function of a traditional piano, which can identify multiple key values and distinguish between light and heavy sound simultaneously. Finally the design results have proved the validity and utility of our performance system by virtue of lower cost and more accurate and adjustable tones.

This paper suggests a hand-free interface based on the facial orientations. The operator's face was observed by the USB camera and the changes in the darkness area of the both nostrils were utilized ...for recognition of the face orientations. When the operator faced to up and downward, the darkness areas of both nostrils were increased and decreased, respectively. On the other hand, the difference between two nostril areas could be caused in cases where the face was turn to the side. Here, these characteristics were reflected to the recognition of the face orientations. The facial orientations were applied to the auto-wheelchair operations, instead of a joystick device.

The Time Machine (TM) is a spike-based computation architecture that represents synaptic weights in time. This choice of weight representation allows the use of virtual synapses, providing an ...excellent tradeoff in terms of flexibility, arbitrary weight connections and hardware usage compared to dedicated synapse architectures. The TM supports an arbitrary number of synapses and is limited only by the number of simultaneously active synapses to each neuron. SpikeSim, a behavioral hardware simulator for the architecture, is described along with example algorithms for edge detection and objection recognition. The TM can implement traditional spike-based processing as well as recently developed time mode operations where step functions serve as the input and output of each neuron block. A custom hybrid digital/analog implementation and a fully digital realization of the TM are discussed. An analog chip with 32 neurons, 1024 synapses and an address event representation (AER) block has been fabricated in 0.5 μm technology. A fully digital field-programmable gate array (FPGA)-based implementation of the architecture has 6,144 neurons and 100,352 simultaneously active synapses. Both implementations utilize a digital controller for routing spikes that can process up to 34 million synapses per second.
