A solid-state imager in a reader for electro-optically reading indicia located in a range of working distances includes an array of image sensors for capturing light from the indicia over a field of view during the reading. By means of a hand-actuatable closed-loop control device, the speed of the toy car can be adjusted to at least two speed levels. The first time is recorded as a last known good time in secure storage on the mobile device. One or both of the heater assemblies can include a heat spreader. In another approach, an appropriate pacing, cardioversion or defibrillation regimen is initiated to treat the actual adverse cardiac condition. A method for monitoring cleaning and sanitization efforts of care providers is also disclosed.
