Question

sometimes babies are born a little early. when this happens, skin sensors are used to monitor a babys vital signs, such as temperature, pulse, and breathing rate. the trouble with skin sensors is they attach to the skin and can be uncomfortable. researchers have developed a new system that doesnt make contact with the baby. instead, it uses wireless cameras to monitor vital signs. another issue with skin sensors is theyre often inaccurate; a babys slight movements can set them off. the cameras in the new system are highly sensitive, however. they detect the newborns pulse by analyzing skin color, which changes slightly with every heartbeat. even at night, babies need to be monitored. the new system deals with low light by using infrared cameras, which use heat instead of light to create images. match the problems with their solutions. small movements cause false alarms. skin sensors can be a source of discomfort. newborns must be monitored at night. problem solution the new system is contactless. the new system uses skin color to monitor pulse. the new system uses infrared cameras.

Explanation:

• For "Small movements cause false alarms": The new system uses skin color to monitor pulse instead of being set off by movements like skin sensors.
• For "Skin sensors can be a source of discomfort": The new system is contactless, so it doesn't attach to the skin like skin sensors.
• For "Newborns must be monitored at night": The new system uses infrared cameras (which work with heat, not light) to deal with low - light night conditions.

Answer:

• Small movements cause false alarms: The new system uses skin color to monitor pulse.
• Skin sensors can be a source of discomfort: The new system is contactless.
• Newborns must be monitored at night: The new system uses infrared cameras.
