A remote sensor data acquisition system for an aircraft includes a plurality of remote sensors co-located onboard the aircraft and adapted to measure one or more aircraft-related parameters. A remote sensor interface is co-located with the plurality of remote sensors. The remote sensor interface includes a communication bus having a plurality of nodes to transmit data from the plurality of remote sensors. A plurality of subsystems are each adapted to receive data from the plurality of remote sensors simultaneously and in real time via the remote sensor interface. A remote sensor data acquisition method for an aircraft includes sensing one or more parameters onboard the aircraft via a plurality of remote sensors and transmitting sensor data from the plurality of remote sensors to a plurality of subsystems independently and in real time via a remote sensor interface.

Systems and methods for vehicle registration are disclosed. A server computer and at least one database are constructed and configured for network communication with at least one vehicle. The at least one vehicle transmits a registration request to the server computer. The server computer assigns a unique registration ID for the at least one vehicle. The at least one database comprises a geofence database storing information of a multiplicity of registered geofences. Each of the multiplicity of registered geofences comprises a plurality of geographic designators defined by a plurality of unique Internet Protocol version 6 (IPv6) addresses. One of the plurality of unique IPv6 addresses is encoded as a unique identifier for each of the multiplicity of registered geofences. The server computer caches the information of the multiplicity of registered geofences on the at least one vehicle.

A master test system may comprise cable modem termination systems, resource servers, provisioning/Session Initiation Protocol (SIP) servers, call management system (CMS) servers, Data over Cable Service Interface Specification/Wide Area Network (DOCSIS/WAN) servers, test controller servers, etc. Servers on the master test system may facilitate tests of devices under test (DUTs) coupled to the master test system. Servers on the master test system and/or slave test systems may facilitate tests of DUTs coupled to slave test systems that are coupled to the master test system. The slave test system(s) may comprise resource servers and test controller servers. In various implementations, the servers on the slave test system(s) may facilitate tests of DUTs coupled to the slave test system(s).

A method for communicating between a master and a plurality of slaves includes generating a communication frame including generating a slave data frame in each slave. The slave data frame has a data packet including one or more data bytes and at least one gap of variable time length comprising no information in the slave data frame. The gap may be at the beginning of said slave data frame before the beginning of the first data byte of said data packet and/or at the end of said data packet after the end of a last data byte of said data packet, where the gaps have a time length dependency based on parameters locally stored in each of said at least one slave. The slave data frame is transmitted sequentially where the gap increases for each subsequent slave.

A master communication apparatus communicates with a slave communication apparatus. A communication interface communicates with the slave communication apparatus. A receiving interface receives information on a first frequency of a station selected by a receiver of broadcast. When a difference between the first frequency included in the information received by the receiving interface and a second frequency of a communication rate used in communication with the slave communication apparatus is smaller than a threshold value, the communication interface changes the communication rate to a third frequency different from the second frequency. When the communication interface changes the communication rate from the second frequency to the third frequency, the communication interface transmits change information indicating a change to the third frequency to the slave communication apparatus.

A communication device includes a processing part and a communication part that communicates with one or more slaves. The processing part has a function of executing communication processing and setting processing. The communication processing is processing for transmitting a main frame including main data from the communication part to one or more slaves in a first period. The setting processing is processing for setting a second period shorter than the first period and a time slot allocated to at least one slave among the one or more slaves in every second period.

The present invention is directed to methods and systems for determining a location of a vehicle within a geofence. The location of the vehicle is determined by a fencing agent on a vehicle. The geofence is defined by a plurality of geographic designators, with the plurality of geographic designators each being associated with an Internet Protocol (IP) address, preferably an IPv6 address.
