摘要： Examples are disclosed for an integrated circuit (IC) device coupled to a battery-operated power supply unit, such as an IC in a mobile computing device or wireless phone, to accurately determine energy usage drawn from the power supply unit under rapidly dynamic circumstances. A current sense signal of a power line from the power supply unit is digitized. The digitized current sense is added to an accumulator at a rate that is approximately proportional to a voltage of the power line from the power supply unit. The accumulator is then outputted and scaled to units relevant to energy measurements. The energy measurement is used to estimate remaining battery life. Triggering the digitization of the current sense signal may be by use of a pulse generation circuit, or by use of an overflow indicator of an accumulator for a digitized voltage sense signal. Other examples are described and claimed.

摘要： A method used in a receiver includes measuring first Received Signal Strength Indications (RSSIs) in respective first communication channels, which are located in a given frequency band and which each have a first channel bandwidth. Based on the first RSSIs, second RSSIs are computed for respective second communication channels, which are located in the given frequency band and which each have a second channel bandwidth that is larger than the first channel bandwidth. At least one of the first and second communication channels over which to receive signals at the receiver are selected using the first and second RSSIs.
