Title: Devices and methods for facilitating data inversion to limit both instantaneous current and signal transitions
Inventor: HOLLIS TIMOTHY MOWRY
IPC: H03K19/00
Filed: 2014-11-10
Abstract: Electronic devices are adapted to facilitate data encoding for simultaneously limiting both instantaneous current and signal transitions. According to one example, an electronic device may perform a first encoding scheme on a group of data bits to be transmitted on a data bus. The first encoding scheme may be performed based on a number of transitions within the group of data bits for each data channel. A second encoding scheme may also be performed on the group of data bits. The second encoding scheme may be performed based on a number of data bits within the group of data bits for each data channel exhibiting a predetermined state (e.g., a one or a zero). After both encoding scheme are performed on the group of data bits, the encoded data bits may be transmitted over respective data channels of the data bus. Other aspects, embodiments, and features are also included.

Inventor: WILSON MICHAEL W N
IPC: E02F9/26
Filed: 2014-10-14
Abstract: A BAS (Burial Assessment Surveys) plow (400) creates a V-trench (501, 511, 521) along the linear route of a pipeline path and an instrumented bottle moving with the BAS plow (400) collects BAS data indicative of the pitch, roll, heading, yaw, three dimensional positioning, speed and depth of the chassis (10), the shearing force applied to the seabed material and the applied tow force. The bottle (470) can be swapped to collect the acquired data or an umbilical can be used to provide a real time stream of data. The Bas plow (400) can simultaneously backfill the created trench (501), (511), (521) leaving an undisrupted seabed, or the pipeline can be laid in the BAS trench, which can also be made deeper and wider by additional trench cutting passes, significantly reducing the total time required for combined BAS and pipeline laying processes. The BAS plow (400) can be released and retrieved over-the-stern of a towing vessel (V).
