Abstract: This invention relates to devices and processes for geophysical prospecting, subsurface fluid monitoring and, more particular, to the use of interferometric techniques using Control Source Electromagnetic (“CSEM”) and Magnetoturelic (“MT”) signals to create images of sub-surface structures and fluids.

Abstract: An avionics system comprises one or more attitude sources, each configured to produce a respective calculated attitude solution; at least one magnetometer configured to measure magnetic field; and at least one attitude monitor configured to use the respective calculated attitude solution from one of the attitude sources to project the measured magnetic field estimate or an Earth Magnetic Field Model (EMFM) estimate such that the measured magnetic field estimate and the EMFM estimate are in a common shared frame. The at least one attitude monitor is further configured to determine a difference between the measured magnetic field estimate and the EMFM estimate in the common shared frame. The at least one attitude monitor is further configured to output an alert, which indicates that the respective calculated attitude solution used to project the measured magnetic field estimate or the EMFM estimate is in error, if the difference exceeds a predetermined threshold.

Abstract: A method to calibrate at least one lever arm between at least one respective global positioning system (GPS) antenna/receiver and a communicatively coupled inertial navigation system is provided. The method includes receiving signals from the at least one GPS antenna/receiver at the inertial navigation system communicatively coupled to a Kalman filter; and estimating, in the Kalman filter, at least one fixed lever arm component while accounting for a bending motion of the lever arm based on the received signals.

Abstract: In a first aspect, a first method is provided. The first method includes the steps of (1) transmitting data on a bus, wherein data is presented on the bus using varying widths; (2) configuring a cyclic redundancy check (CRC) to be performed on the data based on the manner in which the data is presented on the bus; and (3) performing the CRC on the data. Numerous other aspects are provided.

Abstract: A vehicle storage/cargo box system is provided. The system includes at least one access portion, such as but not limited to a door member, for providing access to the interior of a box portion. The box portion includes a weather stripping and door arrangement that allows flat access to the load floor of the box portion. The load floor of the box portion is above the level of the access door's weather stripping flange portion. The system includes various additional access portions, including but not limited to multiple door configurations that articulate in several different manners. The system also includes various storage and support devices such as but not limited to drawers, shelves, tables, and/or the like.

Abstract: Methods and apparatuses that may be utilized to dynamically train communications links between two or more devices based on an error detection history are provided. The error detection history may be based on error detection value comparisons (e.g., CRCs) for a sequence of received packets. According to some embodiments, packets may be accepted only if a number (N) of successive packets have been received without errors, while link training may be automatically initiated only if a number (P) of successive packets have been received with errors.

Abstract: Embodiments of the present invention provide methods, a module, and a system for calculating a credit limit for an interface capable of receiving multiple packets simultaneously. Generally, the multiple packets are simultaneously received at an interface on the second device, each packet being one of a plurality of packet types, and a flow control credit limit to be transmitted to the first device is adjusted based on the combination of packet types of the simultaneously received packets.

Abstract: Methods and apparatuses that may be utilized to automatically train and activate communications links between two or more devices are provided. In some embodiments, one or more state machines may be used to monitor and control the behavior of receive and transmit logic during the automatic training and activation, thus, reducing or eliminating the need for software intervention. As a result, training and activation may begin with little delay after a power-on cycle.
