Abstract: An error correction code for an array of N words of M bits each may be generated by: (i) for each word of the N words, computing a respective set of checkbits for single-error correction of such word; (ii) computing a set of bit-position-related checkbits comprising a bitwise logical exclusive OR of all of the sets of checkbits for single-error correction of the N words; (iii) for each word of the N words, computing a respective parity for the respective set of checkbits and the word itself in order to form a vector of N parity bits; (iv) computing a set of word-related checkbits for single-error correction of the vector of N parity bits; and (v) computing a cumulative parity bit comprising a parity calculation of the set of bit-position-related checkbits, the set of word-related checkbits, and the vector of N parity bits.

Abstract: Embodiments described herein relate to methods and apparatuses for providing a haptic output signal to a haptic actuator. A controller comprises an input configured to receive a force sensor signal from at least one force sensor; and a haptic output module configured to generate a haptic output signal for output to a haptic actuator; wherein the haptic output module is configured to: responsive to determining that the force sensor signal indicates that a force level applied to the at least one force sensor exceeds a first threshold, trigger output of the haptic output signal; and during output of the haptic output signal, adjust the haptic output signal based on the force sensor signal.
