Abstract: In some embodiments, a bathtub heating system may detect a temperature of bathtub fluid (e.g., water, mud, etc.) in a bathtub and may apply heat to the bathtub fluid to maintain a substantially constant temperature (or to provide a user indicated and/or predetermined temperature/time profile). In some embodiments, the bathtub heating system may not use a temperature sensor. For example, the bathtub heating system may use a fluid level sensor to detect when the bathtub fluid in the bathtub is at a sufficient height to operate and may apply a predetermined amount of power to the heating elements to approximately maintain the temperature of the bathtub fluid in the bathtub.

Abstract: A system for decoding variable length coded DVC data and methods of operating the same result in a variable length decoder engine that receives video frames having a plurality of digital interchange format (DIF) sequences and provides contiguous decoded run-length amp pairs. The variable length decode engine comprises a concatenation engine configured to contiguously format a plurality of DIF blocks of a DIF sequence to provide contiguous DCT blocks. The concatenation engine has a controller that utilizes several passes capable of running simultaneously to return the DIF blocks coded according to IEC standards to their original variable length sequences. A run-length amp pair generator coupled to the concatenation engine configured to decode the contiguous DCT blocks to provide the run-length amp pairs.
