Abstract: Disclosed herein are methods and systems for validating an autonomous system that comprises a static-code module and a dynamic-code module, the method including the steps of performing a code-integrity-validation process on the static-code module and performing a behavior-integrity-validation process on the dynamic-code module. In some embodiments, performing the code-integrity-validation process on the static-code module includes performing a signature-verification process on the static-code module. In some embodiments, performing the behavior-integrity-validation process on the dynamic-code module includes using an encrypted-and-signed test vector.

Abstract: Methods and apparatus are provided that relate to receiving a bit pattern that is representative of a binary data sequence; generating a multi-bit data byte sequence that is representative of the bit pattern by, for at least one bit in the bit pattern: outputting a larger-valued multi-bit data byte that is larger than a byte-sequencer reference data byte according to a first criteria, outputting a smaller-valued multi-bit data byte that is smaller than the byte-sequencer reference data byte according to a second criteria; and encoding the generated multi-bit data byte sequence by, for each generated multi-bit data byte: outputting a single bit whose value is indicative of whether the generated multi-bit data byte is larger or smaller than a current reference multi-bit data byte and updating the current reference multi-bit data byte based on the generated multi-bit data byte.

Abstract: A pet abode with sound dampening characteristics comprising an interior space of a pet abode having sufficient dimensions to allow a pet to comfortably reside within the interior space. The interior space is formed from at least three walls where one or more of the walls exhibits sound dampening characteristics. The sound dampening characteristics reduces a one or more sounds originating from a source external to the interior space. That is, the interior space of the pet abode is sound proofed (or sound dampened), allowing a pet to be undisturbed by loud noises outside the interior space.
