Abstract: Systems and methods for reducing the power consumption of end devices in wireless mesh networks are described. In an illustrative, non-limiting embodiment, an end device may include: a controller; and a memory coupled to the controller, wherein the memory comprises program instructions stored thereon that, upon execution by the controller, cause the end device to transmit a frame to a parent device in a wireless mesh network, wherein the frame has a Frame Pending (FP) bit set to indicate, to the parent device, that the end device is ready to receive data from the parent device in the absence of a subsequent data request.

Abstract: A system for providing an enhanced acknowledgement (ENH-ACK) frame is configured to receive an incoming packet transmitted by an external device, determine that an ENH-ACK response is required based on a MAC header of the incoming packet schedule transmission of the ENH-ACK frame to the external device in accordance with a standard turnaround time limit relative to receipt of the incoming packet, determine contents of one or more packet processed fields of the ENH-ACK frame and populate the one or more packet processed fields, and complete transmission of the ENH-ACK frame with the populated packet processed fields.

Abstract: A system comprises an encoder configured to compress attribute and/or spatial information for a point cloud and/or a decoder configured to decompress compressed attribute and/or spatial information for the point cloud. To compress the attribute and/or spatial information, the encoder is configured to convert a point cloud into an image based representation. Also, the decoder is configured to generate a decompressed point cloud based on an image based representation of a point cloud. In some embodiments, an encoder generates time-consistent patches for multiple version of the point cloud at multiple moments in time and uses the time-consistent patches to generate image based representations of the point cloud at the multiple moments in time.

Abstract: A system comprises an encoder configured to compress attribute information for a dynamic point cloud and/or a decoder configured to decompress compressed attribute information for a dynamic point cloud. The dynamic point cloud may include multiple versions of the point cloud at multiple moments in time Attribute values for the point cloud may be compressed at a reference frame using an intra-prediction process and may be compressed at one or more reference frames using an inter-prediction process that takes advantage of temporal relationships between different frames (e.g. versions) of the dynamic point cloud at the different moments in time.

Abstract: A method for managing interactions between at least one peripheral command device and at least one multimedia application exploiting the standard MPEG-4. A peripheral command device delivers digital signals as a function of actions of one or more users comprising: constructing a digital sequence having the form of a BIFS node (Binary Form for Scenes in accordance with the standard MPEG-4), a node comprising at least one field defining a type and a number of interaction data to be applied to objects of a scene.

Abstract: A circuit pack handling system, comprising a handle assembly storage pocket formed in the sidewall of a circuit pack and a carrying handle assembly hinge-mounted within the pocket and adapted to retract substantially within the storage pocket. In a preferred embodiment, the system further comprises a handle locking sub-assembly affixed within the backplane end of the storage pocket between the inner wall of the pocket and the inner leg of the handle assembly to lock the handle assembly into the deployed position. In another preferred embodiment, the system further comprises a coil spring fitted at the gripping member hinge-joint of at least one of the legs so as to spring load the handle assembly whereby the handle assembly automatically flips out from the stored position inside the storage pocket to the deployed position as the circuit pack is pulled away from the shelf frame.
