Currently, most transducers in photoacoustic endoscopy (PAE) are ceramic based, which complicated to fabricate and expensive. In this work, we have for the first time presented a hollow structured epoxy lens-focused transducer that was based on 52 μm thick polyvinylidine fluoride (PVDF) film purpose of PAE imaging. Intensive field characteristic tests were performed with different lens curvatures, results show 6 mm fixed aperture, lateral resolution less than 0.5 can be obtained focal length...
Once there are constant or infrequently changed bits (COIBs) in two adjacent input messages of SHA-2, the switching power data registers (IMD-REGs) used for COIBs will disappear. Meanwhile, when full pipeline SHA-2 is applied a certain application scenario where IMD-REGs can be removed, more area saved as proportion message word increases. This paper proposes new expansion structure to increase IMD-REGs. By inserting expanders last part stages and rescheduling expander, consumption rate...
As one of the biggest contributors to road accidents and fatalities, drink driving is worthy significant research attention. However, most existing systems on detecting or preventing either require special hardware much effort from user, making these inapplicable continuous monitoring in a real environment. In this paper, we present <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DetectDUI</i> , contactless, non-invasive, real-time system...
This paper presents a dynamic phase measurement profilometry (PMP) method based on the simulated annealing algorithm. In PMP for rigid objects, pixel matching is an effective to make one-to-one correspondence in each captured pattern. However, by global traversing algorithm takes up most of time whole reconstruction process. For purpose optimizing and enhancing performance PMP, introduced. By generating random path algorithm, it sufficient locate approximate area measured object. Then...
On-line phase measuring profilometry (OPMP) for a rotating object is proposed. N frames of circular sinusoidal grating patterns are designed in advance, which the transmittance along radial direction and there fixed shifting pitch 2π/N between every adjacent two direction. While measured rotating, projected onto by digital light processing corresponding deformed caused at different positions captured charge coupled device camera. By pixel matching rotation transformation with special marks,...

However, frequently-used method at present, it necessary calculate correlation and traverse whole deformed pattern for motion information of measured object. The huge amount...
An online triple-frequency color-encoded fringe projection profilometry is proposed to measure the complex and discontinuous object at straight-line movement. N frames of color patterns are specially designed. Three grayscale sinusoidal grating with geometric progression frequency growth encoded into red (R), green (G), blue (B) channels separately compose a pattern. If these three phase-shifted steps an equivalent shift phase 2π/N, they can corresponding as above respectively. In order...
We report organic thin film transistors (OTFTs) with pentacene/fluorinated copper phthalo-cyanine (F16CuPc)/pentacene (PFP) sandwich configuration as active layers.

Spurious correlations in training data significantly hinder the generalization capability of machine learning models when faced with distribution shifts real-world scenarios. To tackle problem, numerous debias approaches have been proposed and benchmarked on datasets intentionally designed severe biases. However, it remains to be asked: \textit{1. Do existing benchmarks really capture biases real world? 2. Can methods handle world?} answer questions, we revisit biased distributions datasets,...
