Abstract: In one embodiment, a cable includes a data transmission path disposed about an axial center of the cable and a power transmission path sheathing the data transmission path. The power transmission path includes a power layer and a ground layer, where the power transmission path is characterized by a distributed impedance having at least one frequency dependent impedance characteristic. In some implementations, ground layer shields the data transmission path from electromagnetic interference. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by a capacitance value that satisfies a capacitance criterion at frequencies above a first frequency level. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by an inductance value that satisfies a first inductance criterion at frequencies above a first frequency level.

Abstract: In one embodiment, a method includes: obtaining a power loss value for a cable that couples a device to a power source, where the power loss value is indicative of an amount of power lost through the cable during power transmission from the power source to the device; and determining, based at least in part on the power loss value for the cable, a power budget value indicative of an amount of power received by the device from the power source.

Abstract: The present disclosure relates generating a geofence based on messages received periodically from a plurality of vehicles. A candidate geofence is approximated based on vehicle stoppage data obtained from a datalog of messages. For a given candidate geofence, additional stoppage data is obtained to identify additional vehicle stoppages. The locations of these additional vehicle stoppages are binned to a corresponding geospatial tile. A relatively large cluster of contiguous geospatial tiles form a geofence that may be transmitted to a client device.

Abstract: In one implementation, an apparatus includes: a first reflector portion having a first mount for a first antenna that is configured to operate in a first frequency range, where the first mount characterizes an emission point of a main lobe of the first antenna; and a second reflector portion having a second mount for a second antenna that is configured to operate in a second frequency range that overlaps the first frequency range, where the second mount characterizes an emission point of a main lobe of the second antenna. The second reflector portion is arranged relative to the first reflector portion in order to satisfy a near-field interference isolation criterion between the first and second antennae. In some implementations, the distance between the antenna mounts is less than a distance between the antenna mounts arranged in a plane due to increased spatial diversity between the first and second antennae.
