Abstract: A care system monitoring method for sensing the movement state of a bedridden person is provided. The care system monitoring method includes the following stages. Initial-state information is sensed. A first warning signal is issued to remind the caregiver to perform a movement action on the bedridden person when the time that the bedridden person has been in the initial state exceeds the threshold period. First-state information (which is information that is collected when the bedridden person is in the first state) is sensed after completing the movement action. It is determined whether the bedridden person was moved correctly according to the initial-state information and the first-state information. The first-state information is reset as the initial-state information if it is determined that the bedridden person has been moved correctly. A second warning signal is issued if it is determined that the bedridden person has been moved incorrectly.

Abstract: Disclosed herein are methods for treating an exhaust stream comprising NOx, the methods comprising receiving an exhaust stream and combining it with at least one nitrogen-containing reagent to form a combined stream, heating the combined stream to a reaction temperature ranging from about 870° C. to about 1100° C. to react at least a portion of the nitrogen-containing component, cooling the reacted stream in a first cooling step to a first temperature, and optionally further cooling the reacted stream in a second cooling step to a second temperature, wherein the first cooling step comprises heat exchange between at least a portion of the exhaust stream and at least a portion of the reacted stream. Exhaust treatment systems are also disclosed herein.
