Nap 50 and test cycle

Millions of people are using smartphone apps, bedside monitors, and wearable items (including bracelets, smart watches, and headbands) to informally collect and analyze data about their sleep.  Smart technology can record sounds and movement during sleep, journal hours slept, and monitor heart beat and respiration.  Using a companion app, data from some devices can be synced to a smartphone or tablet, or uploaded to a PC.  Other apps and devices make white noise, produce light that stimulates melatonin production, and use gentle vibrations to help us sleep and wake.

The UC test, Figure 1, has a similar three-phase structure, but is a more aggressive driving cycle than the federal FTP-75 ; it has higher speed, higher acceleration, fewer stops per mile, and less idle time. The UC test is run in the following manner: Phase 1 and Phase 2 are run consecutively, followed by a ten minute hot soak, then Phase 3 which is a duplicate of Phase 1. Emissions from each phase are collected in a separate sampling bag. Overall cycle emissions are calculated in the same manner as the weighted, overall FTP-75 formula, taking actual mileage from the UC into account. In some applications, Phase 3 of the cycle is skipped and only Phase 1 and 2 are run.
