Abstract: The invention allows for a reduction in the amount of salt topically applied to a food product with an oil layer on its outer surface, without adversely affecting the taste of the food product. Salt particles with a particle size greater than the thickness of the oil layer are topically applied to the food product. Because substantially all of the salt particles protrude from the oil layer, they provide a saltiness perception having no meaningful difference from the saltiness perception provided by a control salt applied at higher levels.

Abstract: A method of controlling a vehicle having a transmission system, an engine system, and a braking system includes detecting a braking condition of the braking system. The braking condition is at least one of a brake temperature being above a predetermined brake temperature limit and a braking load being above a predetermined braking load limit. The method also includes detecting a second condition of at least one of the transmission system and the engine system. The method also includes determining whether the second condition satisfies predetermined criteria. Furthermore, the method includes detecting an absolute vehicle acceleration that is below a predetermined acceleration limit. Moreover, the method includes downshifting from a current gear to a lower gear to thereby cause engine braking when the braking condition is satisfied, the second condition satisfies the predetermined criteria, and the absolute vehicle acceleration is below the predetermined acceleration limit.

Abstract: Without battery cell balancing, voltages of multiple series-connected battery cells may quickly become out of balance, which causes some cells of the battery to deteriorate faster than others, and reduces the life cycle of the battery. Embodiments of the present invention address this problem by providing a system for balanced charging of multiple series-connected battery cells. The system includes resistors that are selectably and electrically coupled in parallel with respective battery cells via activation and deactivation of respective switches. The system also includes a control unit that is configured to determine a battery cell having a lowest voltage among the battery cells, and to activate and deactivate the switches as a function of differences in voltages between the voltage of the lowest battery cell and voltages of each of the other battery cells, thus, providing balanced charging of the multiple series-connected battery cells.

Abstract: A communication system and protocol that permits a first device to communicate a plurality of messages in a predetermined order to a user of the first device, where the plurality of messages, their content, and their predetermined order need not be known to the first device until the messages are provided to the first device by a second device. The user of the first device is permitted to move backward or forward through the messages in the predetermined order while utilizing a minimal amount of resources of the first device, such as processor power and memory.

Abstract: To overcome potential problems associated with overflowing counters/timers, embodiments of the present invention include a ping timer and a pong timer offset from each other, and a time checker that accesses at any one timer either the ping timer or the pong timer to determine whether a time interval has passed. Upon passage of the time interval, the time checker switches access from the ping timer to the pong timer before the ping timer reaches an overflow state, thereby avoiding problems associated with counter/timer overflow.
