An angular blinking jamming method based on electronically controlled corner reflectors

Passive jamming is believed to have very good potential in countermeasure community.In this paper,a passive angular blinking jamming method based on electronically controlled corner reflectors is proposed.The amplitude of the incident wave can be modulated by switching the corner reflector between the penetration state and the reflection state,and the ensemble of multiple corner reflectors with towing rope can result in complex angle decoying effects.Dependency of the decoying effect on corner reflectors’radar cross section and positions are analyzed and simulated.Results show that the angle measured by a monopulse radar can be significantly interfered by this method while the automatic tracking is employed.

Dynamic tear meniscus parameters in complete blinking:insights into dry eye assessment

AIM:To investigate the relationship between dynamic tear meniscus parameters and dry eye using an automated tear meniscus segmentation method.METHODS:The analysis of tear meniscus videos captured within 5s after a complete blink includes data from 38 participates.By processing video data,several key parameters including the average height of the tear meniscus at different lengths,the curvature of the tear meniscus’s upper boundary,and the total area of the tear meniscus in each frame were calculated.The effective values of these dynamic parameters were then linearly fitted to explore the relationship between their changing trends and dry eye disease.RESULTS:In 94.74%of the samples,the average height of central tear meniscus increased over time.Moreover,97.37%of the samples exhibited an increase in the overall tear meniscus height(TMH)and area from the nasal to temporal side.Notably,the central TMH increased at a faster rate compared to the nasal side with the temporal side showing the slowest ascent.Statistical analysis indicates that the upper boundary curvature of the whole tear meniscus as well as the tear meniscus of the nasal side(2,3,and 4 mm)aid in identifying the presence of dry eye and assessing its severity.CONCLUSION:This study contributes to the understanding of tear meniscus dynamics as potential markers for dry eye,utilizing an automated and non-invasive approach that has implications for clinical assessment.

Increase of photoluminescence blinking frequency of 3C–SiC nanocrystals with excitation power

Super-resolution optical fluctuation imaging is dependent on the blinking frequency of fluorophores.Consequently,improvement of the photoluminescence(PL)blink frequency is important.This is achieved for 3C–SiC nanocrystals(NCs)by simply increasing the excitation power.Using an excitation of 488 nm with powers of 5μW to 50μW,individual 3C–SiC NC always exhibits PL blinking with a short on-state sojourn time(<0.1 s).A fast Fourier transform method is exploited to determine the PL switching frequency.It is found that the frequency of the bright state increases from 2 Hz to 20 Hz as the excitation power increases from 5μW to 50μW,which is explained by the Auger photonionization model.

Values of blink reflex and electroneurography in diagnosis of facial paralysis

BACKGROUND： The electrophysiological test was mainly achieved by the reaction of nerve fiber to electrical stimulus, usually expressed by the amplitude and latency. Blink reflex and electroneurography （ENOG） are widely applied in facial paralysis, the amplitude would step down, and the latency would prolong when the facial nerve was injured. OBJECTIVE： To compare the value of blink reflex and ENOG in the diagnosis of facial paralysis （Bell＇s palsy）. DESIGN： A controlled trial. SETTINGS： Affiliated Hospital, Chengdu University of Traditional Chinese Medicine; West China Hospital of Sichuan University; Mianyang Hospital of Traditional Chinese Medicine; Sichuan People＇s Hospital. PARTICIPANTS： The patients who had finished the tests of blink reflex （n =207） and ENOG （n =205） were selected from the Affiliated Hospital, Chengdu University of Traditional Chinese Medicine; West China Hospital of Sichuan University; Mianyang Hospital of Traditional Chinese Medicine; Sichuan People＇s Hospital from September 2001 to July 2003. After treatment for 4 weeks, the patients finished tests of blink reflex （n =207） and ENOG （n =205） were randomly divided into primary treatment group （n =68, 69）, acupuncture group （n =71, 66） and comprehensive treatment group （n =68, 70）, respectively. Approval was obtained from the ethic committee of hospital. METHODS： Patients in the primary treatment group and acupuncture group were treated with western medicine, acupuncture and moxibustion alone respectively, and those in the comprehensive treatment group were treated with acupuncture and moxibustion based on western medicine. The whole period of treatment was 4 weeks. The tests of blink reflex and ENOG were carried out using Japanese light and electricity MEB-2200 electromyogram/induced potential instrument for once before and after treatment respectively. The normal value of the latency period of wave RI was within 13 ms, and the difference was 1 - 1.2 ms between the left and right sides. MAIN OUTCOME MEASURES： The latency of wave RI of blink reflect and the latency and wave amplitude of ENOG on the affected and healthy sides before and after treatment were observed. RESULTS： Totally 207 and 205 patients received tests of blink reflex and ENOG, but 17 and 16 cases respectively did not finish the second measurement, finally 190 and 189 cases were involved in the analysis of results. The latencies of wave R 1 on the affected side after treatment were significantly longer than those before treatment （t = - 6.253, P 〈 0.01）; The latencies of wave RI on the normal side were in the normal range before and after treatment; The latencies of wave RI before treatment on the affected side was significantly longer than that on the normal side （t =- 5.896, P 〈 0.01）, but there were no significant differences between the affected and normal sides after treatment （P 〉 0.05）. It was indicated that the latencies of wave RI on the affected side had restored normally, and the blink reflex was improved obviously after treatment. The latency of ENOG on the affected side before treatment was significantly prolonged as compared with that on the normal side （t =2.247, P 〈 0.01）; After treatment, the difference between the affected and normal side became smaller, but remarkable significance still existed （t =10.810, P 〈 0.01）. In spite of the obvious improvement of affected side before and after treatment, there were still significant differences （t =- 8.110, P 〈 0.05）. The wave amplitude on the affected side was decreased after treatment, which was not significantly different from that before treatment （P 〉0.05）. CONCLUSION： After treatment of facial paralysis, blink reflect was greatly improved, there was an obvious hysteresis in the latency of ENOG. Therefore, blink reflect was better than ENOG in the early diagnosis, while ENOG was suitable for evaluating the prognosis. The ENOG examination was better than blink reflex at middle and late period.

Eye Blink Responses to the Four Basic Taste Stimuli in Healthy Young Humans

Taste stimuli can elicit facial responses, and the facial responses may be useful indexes of taste sensations. In this study, we propose that eye blinking is also elicited by taste stimuli and we examined eye blink responses in six healthy young adults. Low and high concentration solutions of the four basic taste qualities (sweetness, saltiness, sourness, and bitterness) and distilled water were delivered via a silicone tube. Facial responses were recorded by a video camera and eye blink responses were identified. The number of eye blinks in the 5 s following stimulation, and the latency and duration of the first eye blink, were quantified. High concentrations of sour and bitter solutions increased the number of eye blinks (195% and 227%, respectively;P P

Alterations in blink and masseter reflex latencies in older adults with neurocognitive disorder and/or diabetes mellitus

BACKGROUND Blink and masseter reflexes provide reliable,quantifiable data on the function of the central nervous system:Delayed latencies have been found in patients with neurocognitive disorder(ND)and type 2 diabetes mellitus(T2DM),but this has not been studied in patients with both pathologies.AIM To investigate if older adults with ND plus T2DM have prolonged latencies of blink and masseter-reflex and if they were associated with disease progression.METHODS This cross-sectional study included 227 older adults(>60 years)from Colima,Mexico.Neurocognitive disorder was identified by a neuropsychological battery test,and T2DM identified by medical history,fasting glucose,and glycosylated hemoglobin.Latencies in the early reflex(R1),ipsilateral late(R2),and contralateral late(R2c)components of the blink reflex were analyzed for all subjects,and 183 subjects were analyzed for latency of the masseter reflex.RESULTS In 20.7%of participants,ND was detected.In 37%,T2DM was detected.Latencies in R1,R2,and R2c were significantly prolonged for groups with ND plus T2DM,ND,and T2DM,compared with the control group(P<0.0001).The masseter reflex was only prolonged in older adults(regardless of T2DM status)with ND vs controls(P=0.030).In older adults with ND and without T2DM,the more the cognitive impairment progressed,the more prolonged latencies in R2 and R2c presented(P<0.01).CONCLUSION These findings suggest that blink and masseter reflexes could be used to evaluate possible changes in brainstem circuits in older adults with ND and T2DM.

Comprehensive Study on the Basis of Eye Blink, Suggesting Length of Text Line, Considering Typographical Variables the Way How to Improve Reading from Computer Screen

The advent and extensive use of computer and increasing development of different technologies it is important to increase the awareness of issues related to the electronic text or text presentation on computer screen. The usage of web shows the importance of usability and readability of the web applications or sources provide by the web and web textual contents. Web application fails to encounter the user’s requirements in effective manner specially related to textual information, because the designers are unaware from some of the important factors effecting readability, reading from the screen. In this regard, this study is the continuation of the previous work that has been done for the improvement of readability, to handle the readability issues on the basis of Eye Blink for male participants and female participants. To achieve general recommendations for suitable or optimum length of text line for all type of users on the bases of eye blink. Basically during reading from the computer screen focus losses at two positions, when eye blink in the middle of text line and when text line ends. The study specifies suitable length of text line on the basis of Eye Blink, assuming three typographical variables i.e. font style, font color, font size, and with white background, which improve the overall readability or reading from computer screen. The study also shows two important things the degree of understandability and the degree of attractive appearance of different combination.

Development of a Stimulation System for the Gustatory Eye-Blink Response in Humans

An inexpensive stimulation system for recording eye-blink responses elicited by taste stimuli has been developed using a manually controlled syringe and tasimetric sensor. The system requires neither an intra-oral device nor clamping of the head and tongue for natural eye-blink responses. The data recorded by the system have a high temporal resolution that is likely to be sufficient for the analysis of eye-blink responses based on video recordings.
