Abstract: A method for managing roles of device nodes in an aggregated system. Information regarding a device node of an aggregated node group is determined. Each device node of the aggregated node group has multiple power level states. One of a plurality of roles of the device node is determined based upon the information. Each role has an associated power level state. The power level state associated with the role or function of the device node is enabled. The device node is instructed to actuate the determined role.

Abstract: In some examples, a micro light-emitting diode (μLED) panel may include a μLED including at least two electrodes (or bond pads), and a ferromagnetic material included in the at least two electrodes (or bond pads) and/or disposed on the at least two electrodes (or bond pads). The μLED panel may further include a panel substrate including ferromagnetic material selectively disposed at least at two locations corresponding to locations of the at least two electrodes (or bond pads) to align a plurality of μLEDs including the μLED onto the panel substrate.

Abstract: In one example, a method of relaying energy to device nodes is disclosed. The method includes transmitting energy waves into an aggregated node group with multiple device nodes. The transmitted energy waves are to actuate the device nodes into a higher power state and in part for storage by the device nodes. Energy streams reflected by the aggregated node group may be captured to indicate actuated and non-actuated device nodes. The method determines a target low power state device node from the non-actuated low power state device nodes and determine neighboring higher power state device nodes proximate to the target low power state device node. A communication signal may be transmitted to the neighboring higher power state device nodes directing them to relay the stored energy to the target low power state device node to actuate the target low power state device node into a higher power state.

Abstract: One example of a device includes an antenna, a memristor code comparator, and a controller. The antenna is to receive a wake up signal. The memristor code comparator is to compare the wake up signal to a reference signal. The controller is to provide a trigger signal to wake up the device in response to the wake up signal matching the reference signal.
