Managing energy usage in mobile devices
摘要
說明書
When hand held computers, such as mobile devices, travel from a cool environment to a warm environment the display screen/scanner windows may fog and/or frost over. Energy transfer elements such as heater elements within a mobile device may be turned on whenever the mobile device goes into a cold environment to prevent the windows from fogging or frosting over, but this uses battery power somewhat indiscriminately, and reduce operational run times. Example embodiments of the present invention turn on the heater elements controllably, under conditions where a local dew point may be approached. Certain example embodiments use battery power controllably and under most conditions, may extend battery charges and time between charges, and associated operational run times, while deterring the fogging and/or frosting of the windows.
In certain example embodiments, environment sensors are placed that broadcast the current temperature and humidity levels of a location in which the mobile device is tracked.
In certain example embodiments, environmental data can be downloaded that constitute a local weather report.
In certain example embodiments, the information is transmitted directly to the handheld device via a low power RF signal, such as like Bluetooth Low Energy (BTLE), or via an Internet of Things (IOT).
In certain example embodiments consistent with the present invention, the sensor information is obtained by the mobile device using a network associated with a heating, ventilating, and air conditioning (HVAC) infrastructure. The information is sent via the HVAC network infrastructure (e.g., over a network associated therewith) to the mobile device or other handheld computer based on its location at the time.
