Abstract:
Described are devices, systems and methods for real-time remote control of vehicles with high redundancy. In some embodiments, two copies of at least one control command are received using two different wireless communication protocols, and are compared. The at least one control command is executed when the two copies are in agreement, but is rejected when the two copies differ. In other embodiments, additional wireless communication protocols may exist to provide a redundant mode of communication when one of the two different wireless communication protocols are unavailable. In yet other embodiments, redundant GPS units may be used to determine availability of any of the communication protocols, and relevant control commands may be downloaded in advance to circumvent the lack of coverage.

Apparatus, reagents, pre-treated proteins and methods for dying proteins in electrophoresis run gels, and for instantly viewing such dyed protein samples in an electrophoresis gel. A protein mixing solution containing a fluorescence dye is mixed with a protein sample so that fluorescence dyes within the protein mixing solution conjugate to proteins within the protein sample. Prior to performing electrophoresis, the protein sample mixture containing fluorescence dyed proteins is introduced into an electrophoresis gel, whereby after performing electrophoresis on such gel, the fluorescence dyed proteins are visible in the gel without the need to remove such gel from its container or cassette holder.

Abstract:
At a node (110) of a wireless network (100), equalisation operations performed on signals received from a transmitter (130) are adaptively switched to be equalised by an iterative turbo receiver (210) or a linear receiver (230) A theoretical expression of a post-equalization SINR of a capacity-achieving receiver is used to estimate the post-equalization SINR performance of the turbo receiver (210). The estimated post-equalization SINR performance is then, used as a basis to determine whether the received signal is to be equalized by the turbo receiver (210) or the linear receiver (230).

Abstract:
In one of its aspects the technology disclosed herein concerns a method of operating a receiver (30). The method comprises performing symbol detection by (1) receiving a frequency-domain signal that comprises contribution item time-domain symbols transmitted from one or more transmit antennas; (2) generating a transformation matrix and a triangular matrix based on a frequency domain channel response; (3) using the transformation matrix to transform the received frequency-domain signal to obtain a transformed, frequency-domain signal; and (4) performing symbol detection by performing plural stages of detection, each stage of detection using elements of the transformed frequency-domain received signal associated with the detection stage.
Abstract:
Device and method for processing 4-dimensional (4-D) seismic traces. The method includes receiving at least two vintages of seismic traces recorded by seismic receivers for a same subsurface area, wherein said seismic receivers are located at the ocean floor; applying up-down deconvolution to each of said vintages of seismic traces to obtain a representation of a reflectivity of said subsurface area from each vintage of seismic traces; and redatuming the up-down deconvolution result of each vintage from the ocean floor to a desired water depth of the ocean to reduce one or more changes in said seismic traces associated with water layer variations between recordings of said series of seismic traces. The redatumed seismic data is used to generate one or more images representing characteristics of said subsurface area.

Abstract:
Channel quality metrics (such as SINR, BLER, and the like) are derived from a raw bit error rate (RBER), defined as the error rate of raw bits output by a demodulator. These initial raw bits are decoded and error-checked (or error-corrected). The error-free decoded bits are re-encoded, and the regenerated raw bits are compared to the initial raw bits to determine the RBER. The RBER is then converted to SINR, BLER, or other channel quality metric. The RBER-based metrics are derived from a data channel rather than reference signals, and hence more accurately reflect deviations from nominal transmission power level, and include receiver demodulator impairments.
Abstract:
Teachings presented herein offer reduced computational complexity for detecting a plurality of symbol blocks, even for symbol blocks that comprise the combination of a relatively large number of symbols The teachings perform two or more stages of detection assistance to successively reduce the number of candidate combinations of symbols to be considered for a symbol block when detecting the plurality of symbol blocks. In particular, the teachings identify a reduced set of candidate symbol combinations for at least one symbol block m the plurality ?f symbol blocks, and then jointly detect each of one or more distinct groups of symbols in the symbol block to determine from that reduced set a final reduced set of candidate symbol combinations. Detection of the plurality of symbol blocks limits the candidate combinations of symbols considered for a symbol block to the final reduced set of candidate symbol combinations identified for that symbol block.
