Abstract: What is disclosed is: a method for natural intelligence (NI) processing for a wireless communication system. The method comprises receiving perceptions comprising a plurality of transmitted symbols, and determining, based on the received plurality of transmitted symbols, whether a suitable posterior model is available. when a suitable posterior model is available, the model is retrieved. The retrieved posterior model is used to estimate a BER, and the estimated BER is communicated to an executive subsystem. when the estimated BER is below a threshold, a prospective action is selected. The selected prospective action is tested in a virtual environment to determine whether the prospective action is beneficial. when the selected prospective action is beneficial, it is communicated to a feedback subsystem. Signals comprising the selected prospective action are received. An adjustment to implement the selected prospective action is determined, and signals to perform the determined adjustment are transmitted.

Abstract: A storage device may recover from a firmware failure that places the storage device in an undetectable state. The storage device includes a memory device to store recovery firmware. A storage device controller includes a failure detector module that may identify the firmware failure when a periodic signal is not received by the failure detector module from a firmware thread, when the failure detector module determines that an initialization counter value is greater than an initialization threshold, or when the failure detector module receives a notification of a predefined number of power cycle events occurring with a given time frame. Upon identifying the firmware failure, the failure detector module updates a boot address. A recovery module May obtain recovery firmware from the memory device, based on the boot address, to recover the storage device in a recovery mode, and perform phased recovery actions to restart the storage device.

Abstract: An apparatus and method for encoding data are disclosed that may allow for performing periodic calibration operations on a communication link. A controller may determine multiple possible values for a reference voltage used with the communication link based on an initial value. Calibration operations may be performed using each possible value, and the results of the operations scored based on the width of data eyes measured during the calibration operations. The controller may then select a new value for the reference voltage from the multiple possible values dependent upon the scores of each of the multiple possible values.

Abstract: An optical waveguide system exhibiting reduced noise includes a varying dispersion optical waveguide fiber and a high frequency electrical filter. The varying dispersion fiber shifts the frequency spectrum of the noise relative to that of the signal so that the noise can be filtered with substantially no effect on the signal. The varying dispersion fiber is a passive component of the optical system and is compatible with optical connecting and splicing.

A primary coating of light absorbing material may be positioned between the cores to further reduce cross-talk. Also provided are methods for manufacturing the same and wavelength division multiplexing systems using the same.
