Patent number: 9848384Abstract: Apparatuses, methods, apparatuses, and systems for of selectively deactivating portions of a receiver based on dynamic measurements are disclosed. One embodiment of a method includes receiving, by the receiver, a wireless signal, identifying a packet within the wireless signal, determining whether the packet cannot be decoded with a reliability greater than a threshold, and powering down at least a portion of the receiver after determining that the packet cannot be decoded with the reliability greater than the threshold.Type: GrantFiled: February 11, 2016Date of Patent: December 19, 2017Assignee: Imagination TechnologiesInventors: Sujai Chari, Meesaraganda Surendra Raju
