The present invention provides apparatuses and methods for boiling a liquid such as water. The liquid is heated at full power when the measured temperature of the liquid is below a first predetermined threshold. When the temperature is above the first predetermined threshold and below a second predetermined threshold, partial power, which may be based on the duty cycle, is applied to the heater. When the measured temperature of the liquid reaches the second predetermined threshold, power is removed from the heater after a predetermined time. When the increase of the measured temperature is less than a predetermined temperature change during a predetermined time duration, it is determined that the liquid is boiling and power is removed to the heater. If the level is too high or too low, an alarm may be activated and / or power removed from the heater.

A method and apparatus are disclosed for reducing leakage power in a cache memory. A cache decay technique is employed for both data and instruction caches that removes power from cache lines that have not been accessed for a predefined time interval, referred to as the decay interval. The cache-line granularity of the present invention permits a significant reduction in leakage power while at the same time preserving much of the performance of the cache. The decay interval is maintained using a timer that is reset each time the corresponding cache line is accessed. The decay interval may be fixed or variable. Once the decay interval timer exceeds a specified decay interval, power to the cache line is removed. Once power to the cache line is removed, the contents of the data and tag fields are allowed to decay and the valid bit associated with the cache line is reset. When a cache line is later accessed after being powered down by the present invention, a cache miss is incurred while the cache line is again powered up and the data is obtained from the next level of the memory hierarchy.

A length-adjusting arrangement adjusts the length of the guide arm to correspond with the width of the tunnel, and an angle-adjusting arrangement adjusts the angle of the guide arm relative to the horizontal surface of the base member. The base member is mounted on a sled for lateral displacement transversely of the flatbed.

A multi-component compound for the simultaneous treatment of nicotine addiction and the side effects of nicotine withdrawal, such as excessive appetite. The first component is a bivalent negative sulfur compound in an amount effective to control nicotine craving or the withdrawal symptoms resulting from nicotine withdrawal. The bivalent negative sulfur is selected from a group that includes, but is not limited to, alkyl sulfides, colloidal sulfur, hydropersulfides, organic thio compounds or their salts. The second component is a serotonin precursor, such as tryptophan or its derivative 5-HTP, which is used to assist the body in producing more serotonin which in turn suppresses appetite. The appetite suppressant(s) are combined with the bivalent negative sulfur compound(s) to provide a single compound that reduces nicotine craving and simultaneously suppresses increased appetite resulting from nicotine withdrawal. The compound alters the perceived taste of tobacco smoke such that it is no longer enjoyable.
