Abstract: Methods and systems are provided for cooling hot spots on a body coil assembly of an MRI system. In one embodiment, an airflow guide of a body coil assembly of an MRI system comprises a first surface that forms an air passage when the airflow guide is positioned on the body coil assembly, the air passage enclosed by the first surface and a second, outer surface of an RF coil of the body coil assembly, the airflow guide configured to channel cool air generated by a fan to the second, outer surface of the RF coil. The airflow guide may be arranged circumferentially around a portion of the RF coil at one or more ends of the RF coil. The airflow guide may be manufactured as a plurality of airflow guide segments that are glued together.

Abstract: An image sensor includes a pixel array including first to third pixel groups, including first to third color pixels having first to third colors and outputting first to third pixel signal for the first to third colors, and an image signal processor receiving the first to third pixel signals, wherein the image signal processor, when the first pixel signal is a bad pixel signal, performs bad pixel correction on the first pixel signal based on the second pixel signal and the third pixel signal and generates a remosaiced pixel signal for the first through third colors by remosaicing the second and third pixel signals based on each other, and the corrected pixel signal and the remosaiced pixel signal represent information in which the first through third color pixels are rearranged in a second pattern having a higher frequency than a frequency of a first pattern.

Abstract: The present invention relates to a sample collection and testing device for analyzing and testing an analyte in a liquid sample. The sample collection device includes a collection inner cavity and a collection outer cavity. The collection inner cavity is disposed inside the collection outer cavity. The collection inner cavity communicates with the collection outer cavity via through holes at a bottom portion of the collection inner cavity. The collection inner cavity is movable between a first position and a second position relative to the collection outer cavity. When the collection inner cavity is at the first position, the liquid sample is collected into the collection outer cavity. When the collection inner cavity is at the second position, the liquid sample is discharged out of the collection outer cavity.

Abstract: A dual-sensor signal collecting circuit comprises circuit (11), a second sensor signal collecting circuits, an AD sampling circuit, an AND gate determination circuit and a collected signal averaging circuit. Output ends of the sensor signal collecting circuits are connected to respective input ends of the AND gate determination circuit, respective input ends of the collected signal averaging circuit and a first AD sampling port of the AD sampling circuit; an output end of the AND gate determination circuit is connected to a power supply end of the collected signal averaging circuit; an output end of the collected signal averaging circuit is connected to the first AD sampling port of the AD sampling circuit. When the sensors operate normally, the collected signal averaging circuit outputs an average sampling value to the first AD sampling port, when one is damaged, a sampling value of the one operating normally is output to the first AD sampling port.
