Processing involving multiple sensors

摘要

In a particular embodiment, an apparatus includes a first sensor that has an active mode and a dormant mode. When operating in the active mode, the first sensor has a first power consumption level. The apparatus further includes a second sensor that has a second power consumption level that is less than the first power consumption level (i.e., the power consumption level of the first sensor). The second sensor is deactivated when the first sensor is operating in the active mode. The apparatus includes logic to activate the second sensor when the first sensor transitions from the active mode to the dormant mode.

主权项

1. An apparatus, comprising:
a first sensor having a first power consumption level when operating in an active mode, the first sensor further having a dormant mode; a second sensor having a second power consumption level that is less than the first power consumption level, wherein the second sensor is deactivated in response to the first sensor operating in the active mode; and circuitry configured to determine whether to transition the first sensor from the active mode to the dormant mode, wherein the first sensor includes a video camera and the second sensor includes an echolocator, wherein the echolocator generates an ultrasound signal, and wherein the echolocator detects a return of the ultrasound signal, the circuitry further configured to activate the second sensor based on the first sensor transitioning from the active mode to the dormant mode.
