Researchers at University of Guelph borrow RFID technology for pathogen transmission studies
Researchers at the University of Guelph have been testing radio frequency identification technology to track the movements of horses and staff to determine how the disease is transmitted. The technology uniquely identifies the person wearing the RFID tag, which itself can collect the data of the tag with which it is in contact. The solution eliminates the need for researchers to install card readers in stables and fields. "We are using computer simulations to find trends that could lead to the spread of the disease," said Amy Greer, assistant professor of population disease modeling at the Ontario Veterinary College of the University of Guelph. Researchers at University of Guelph borrow RFID technology for pathogen transmission studies (Researchers put each label in a sealed plastic sleeve to prevent it from being contaminated and wasted.) In the past, Greer said, potential infections were based on the notion that a group of animals in restricted areas had the same risk of being affected by infection. She pointed out that this view oversimplifies the risk of infection for each animal and does not take into account factors such as the care of animals and the causes of the disease. Greer said researchers hope that hospitals, like hospitals, use technology to track the movement of people and people around them to understand the risks of disease transmission. Therefore, they studied RFID technology. However, the hospital has Wi-Fi networks and power supplies that make it easier to capture information and download it into the software, Greer said. The stables do not have this infrastructure. As a result, the group has developed a system that is currently in use at 3 sites. The system, horses and staff wear a high memory transponder, can transfer data to each other, and can be downloaded in the network area. In this way, the user does not need to install the gateway in the field. The technology consists of the OpenBeacon active 2.4 GHz proximity tag and the Nordic nRF51822 Bluetooth low energy (BLE) chip, which is attached to the horse by a hook. The unique ID number of each tag is tied to a person or a horse, and the tag ID is stored in a software developed by the university. Although the technology can use BLE to communicate with beacon devices, researchers now use only the RFID capabilities. Each tag has a built-in 8M storage capacity. When a horse or a person wears a tag that is within 2 meters of another tag, the tag transmits ID number information to each other. Then store the data in two tabs. The built-in button battery life of these labels can last up to one week. Researchers put each label in a sealed plastic sleeve to prevent water and dirt and then attach it to the straps. Researchers at University of Guelph borrow RFID technology for pathogen transmission studies (There is a tag on the bridle, and when the tag is within the range of another tag, the tag will read the signal to another tag) At the completion of each study, researchers linked the tags to a computer to upload the data. OpenBeacon tags can also use BLE to send data to mobile devices, but the researchers are not yet enabled. These data will not only reflect the label information contact with each other, but also reflect the contact order and duration. Due to the size of the horse and the presence of fluid in the body, Greer said it is a challenge to ensure that tags read each other efficiently, which is also a barrier to the spread of RF signals. The team considered attaching two labels to each one immediately, one on the front and one on the back, but only the tag on the bridle was chosen because the face-to-face contact triggered the infection. All three of the university's studies were conducted this year and at different racecourses. The first racecourse has 9 mark and 5 mark staff, while the largest racecourse has 30 mark horses and 10 mark staff. So far, the system has collected 300,000 staff contacts. The group plans to deploy it again this spring and summer. Greer said that this summer, we will analyze these data. The team will then determine the pathways that may lead to pathogen transmission.
LED Car Light
LED car lights refer to the use of LED technology inside and outside the car for external and internal lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load testing. LED car lights can be widely used to create the environment in the car. The life span is 50,000 hours. The structure of the LED is sturdy and not easily affected by vibration. The light output brightness will not significantly decrease during use. LED car lights are suitable for various lighting applications of automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signal lights, daytime running lights, pedal lights, instrument lights, license plates Lights, door lights, interior lights, width indicator lights, navigation, entertainment systems, backlights and indicator lights, etc.
1. Energy saving: Light-emitting diodes are directly converted from electrical energy to light energy. Compared with ordinary car bulbs, the power consumption is only 1/10 of that of traditional lamps, which can better save fuel consumption and protect car circuits from being burned by excessive load currents.

2. Environmental protection: There are no ultraviolet and infrared rays in the spectrum, low heat generation, no radiation, low glare, and the waste can be recycled, no pollution, no mercury, and safe touch. It is a typical green lighting light LED source.
3. Long lifespan: There is no loose part in the lamp body, and there are no shortcomings such as easy burning, thermal deposition and light decay of the filament. Under the appropriate current and voltage, the service life can reach 80,000 to 100,000 hours, which is longer than that of traditional light sources. More than 10 times longer. (It has the characteristics of one-time replacement and lifetime use)
4. High brightness and high temperature resistance. (Electric energy is directly converted into light energy, and the heat is small, and it can be touched by hand, which is safe and secure)
5. Small size. The designer can change the lamp mode at will to make the car diversified. Automobile manufacturers' favor of LEDs is entirely determined by the advantages of LEDs themselves.
6. Good stability, strong anti-vibration performance of LED: resin encapsulation, not easy to break, easy to store and transport.
Seven, the luminous purity is high, the color is clear and bright, no lampshade is needed to filter the light, and the light wave error is within 10 nanometers.
8. The response speed is fast, no hot start time is needed, and it can emit light within microseconds. The traditional glass bulb bulb has a 0.3 second delay, which can prevent rear-end collision and ensure driving safety.
