Humanoid Robot Application  as COVID-19 Symptoms Checker  Using Computer Vision and Multiple Sensors

Novel Corona Virus (nCoV) infects human’s respiratory system. It spreads easily when an infected person makes a close contact with other people. To prevent its massive spread, it is necessary to ensure anyone coming to a certain place is not being infected. The symptoms include high body temperature (≥37.5°C) and low oxygen saturation level (≤95%). This day, most places only check the human body temperature. Thus, the authors are interested to make an attempt to design a system that is able to measure both human body temperature and oxygen saturation level. This work also applies the 7-DoF Upper-Body of Humanoid Robot to prevent virus spread from and to the employee. The system will detect the coming of visitors by using face detection. It requires 7.24 seconds to detect the visitor without a mask, and 1.26 second when the visitor wears a mask. The body temperature measurement was done using GY-906 temperature sensor with an error of 0.51%. For the oxygen saturation level measurement, MAX30100 pulse oximeter module was applied and showed an error of 0.78%. In addition, the upper-body of humanoid robot will perform some gestures to instruct the visitors in every process of the system. The implemented 7-DoF upper-body of humanoid robot has 93.33% gesture comprehension rate. In conclusion, the overall system has been tested and showed success rate up to 75%.

Oxygen Saturation Level

The level of oxygen saturation in the blood is important to know the health condition of the body. If the human body lacks or excess oxygen, it will cause illness and other bodily system work disorders. One of the tools to detect the oxygen saturation level is the Pulse oximeter. Previous research has successfully designed a Pulse oximeter based on Arduino. The pulse oximeter produces a photoplethysmograph (PPG) signal that corresponds to the standard PPG signals in 20 test samples. PPG signals can be processed to provide information on oxygen saturation (SpO2) levels in the blood. In this research, validation of the Pulse oximeter is compared with a commercial pulse oximeter, the digital oximeter JZK-301. The results obtained from this validation are the smallest deviation errors are 4.83% while the largest errata is 22.51%. The greatest accuracy of 95.17%, of respondents number 16 and the smallest accuracy is 77, 49%, that is the number of respondents 12. The average deviation of 20 data is 12.82% with the resulting accuracy is 87, 18%. This indicates that the self-designed pulse oximeter has good efficiency and can be developed further

The objective of this work is to investigate the potential use of a thermoelectric generator (TEG) in harvesting human body heat at four body locations namely forehead, wrist, palm and calf for different human activities in Malaysia. Important parameters for this experiment are human body temperature, room temperature, output voltage, output resistance and output power. A healthy male and female perform a series of activities including resting, walking and running for 10 minutes in an indoor setting. Results indicate the relevant effects of temperature and movement on producing power from human body heat. Different parts of the body have different temperatures, thus creating different output powers. Results show that as the movement increases, the human body temperature and the amount of energy harvested also increase. It is also observed that forehead provides the highest amount of power generated during running activity. When the body temperature is above 35 °C, the TEG can generate power more than 5.0 mW. The highest power generated during the experiment is 9.5 mW. Even though Malaysia is known as a hot and humid region, TEGs can be feasibly utilized as a wearable device that converts human heat energy into electrical energy.

AimsReferrals to the psychiatric Liaison team in A&E seem to come in the afternoon in kismet as the day shift is ending. This study looked at the timing distribution of referrals to try improve amount of jobs being handed over to the evening shifts.MethodReferrals made to Homerton University Hospital (HUH) psychiatric liaison was parsed into 1 hour bins and plotted as a histogram (data between August 2016–October 2019. N = 14182). The data were compared to diurnal human body temperature variation, as well as data published on Hospital Accident & Emergency Activity 2019–20 (digital.nhs.uk) for Ambulance attendances.ResultReferrals to HUH liaison team appear to closely follow the average human body temperature variations per hour (Pearson Correlation coefficient = 0.90). A peak appears to occur around 4 PM, and a low at 7AM. The referrals data also mirrored timings of official Hospital Episode Statistics (HES) reports 2019–2020 for ambulance attendance in England (Pearson Correlation coefficient = 0.94).ConclusionAttendance to A&E and referrals to psychiatric liaison appear correlated to a circadian bound rhythm. “The 4PM referrals rush” appears to be a genuine phenomenon replicated in not only HUH mental health referrals, but general ambulance attendance throughout all of England. The body temperature analogue for circadian rhythm may be humorously applied here to correlate with the increased referral rates to A&E; the emergency department could be said to be truly heating up in the afternoon. Indeed temperature and activity has already been shown to link strongly via the Arrhenius equation in cricket activity such as chirps per minute. The conclusions drawn here are that acute mental health attendances, like general health attendances as a whole follow underlying but powerful patterns, and provisions might best be allocated to address this rather than thinking of fixed 9-5 working schedules.

Abstract Infrared thermography thermometer is a non-contact temperature measuring equipment, which is widely used in the stage of large-scale epidemic of the covid-19 pandemic. It is used for rapid screening of human body temperature in crowded places at the entrance and exit of airports, docks, shopping malls, stations and schools. But when the outdoor temperature approaches or exceeds the body temperature in summer, can this method of measuring body surface temperature by infrared thermal imager be used as a standard for screening fever? Under the condition of high temperature in summer, the field experiment of measuring body temperature by infrared thermal imager is carried out, the experimental results are analyzed. We recommend the use of relative temperature difference for screening patients with fever.

Human Body Temperature

The aim of the work is to increase the reliability of remote methods of measuring the surface temperature of the human body. Common use of non-contact infrared (IR) devices for temperature screening. But it is important to pay attention to the accuracy of these systems to identify visitors or staff with an infectious disease. The following areas of improvement of metrological characteristics of non-contact devices for measuring human body temperature in a pandemic are identified: 15 cm, the presence in the equipment of a calibrated thermostable source of radiation, called the absolute black body (APT). An effective method of providing the most accurate measurements of skin surface temperature is associated with the use of "baseline sampling". To implement this method, a thermal imager measures the temperature of a specially selected group of perfectly healthy people, with whom the temperature of all others is compared. As a result of the conducted research the requirements to carrying out measurements of body temperature by IR thermometers for reception of reliable results are substantiated and offers on maintenance of these requirements for the purpose of increase of collective safety are put forward. It was found that the lack of calibration when measuring the body temperature of 50 university visitors with an IR thermometer is the cause of gross systematic error, which needs to be corrected by correcting. To increase the reliability of measurements, it is necessary to develop and test a simple and effective method of calibrating IR thermometers, suitable in normal operating conditions. Therefore, it is necessary to calibrate the IR thermometer before the measurements, which eliminates the systematic measurement error. The practical significance of the study is to determine the optimal conditions for the use of the device for non-contact temperature screening in a pandemic. The results of the work will be useful both for further study of increasing the reliability of the results of remote temperature measurement, and may be useful in the learning process.
