Abstract: There are provided techniques for transmitting, receiving and coordinating pilot sequences, and for evaluating channel properties. A pilot signal may comprise a pilot sequence, which comprises a plurality of symbols with: at least one first set of equally spaced symbols, and at least one second set of equally spaced symbols, the symbols of the at least one second set of equally spaced symbols being inserted in between the symbols of the at least one first set of equally spaced symbols, It is possible to select: the at least one first set of equally spaced symbols in such a way that each first set of equally spaced symbols represents a respective first code and the at least one second set of equally spaced symbols in such a way that each second set of equally spaced symbols represents a respective second code. each first code and each second code may be selected from a set of codes in which each code of the set of codes is orthogonal to at least one other code of the set of codes.

Abstract: A power tracking system includes a power application that receives live power data from multiple power devices that are operably connected to a personal area network (PAN) during operation of the PAN. The system stores the live power data and uses historical power data that includes previously collected live power data corresponding to the multiple power devices that was collected during previous operations to generate prediction data, including a predicted runtime of the PAN. The live power data and prediction data are displayed to a user on a user interface and is used by components of the system to model and predict power requirements and power usage of the PAN components.

Abstract: A bridge system includes messaging middleware that is configured to operate on a multi-protocol soldier personal area network (PAN) and to enable sharing of data with multiple applications in an Android OS. The bridge system is implemented on smart and semi-smart multi-protocol hubs and is used to support sharing of live power data between PAN components. The data is displayed to a user on a user interface and is used by components of the system to model and predict power requirements and power usage of the PAN components.
