An active low-pass current filter apparatus and method reduces conducted emissions above a predefined cutoff frequency at high power levels. The apparatus and method use a bidirectional DC-DC converter to minimize current fluctuations on a power lead that may result in conducted emissions above the predefined cutoff frequency. The bidirectional DC-DC converter absorbs current from the power lead and feeds current to the load lead as needed to compensate for the current fluctuations on the power lead. Power to the DC-DC converter is provided by a separate auxiliary power source. A monitoring circuit compares the voltage level of the auxiliary power source to a reference voltage and compensates for variations in the voltage level of the auxiliary power source without interfering with the suppression of the conducted emissions.

A Flash-based memory system comprises a plurality of Flash memory devices, a Flash controller communicating independently with each Flash memory device to perform memory operations, a power circuit providing power the Flash memory devices, and a CPU configured to perform a controlled powering down procedure upon detecting a power failure. In some embodiments, the Flash-based memory system includes a backup power source having a charge storage device and charging circuitry, the CPU configured to perform one or more test procedures on the charge storage device to provide an indication of a charge storage capacity of the charge storage device. A plurality of Flash-based memory systems may be mounted on a Flash-based memory card, and multiple such Flash-based memory cards may be combined into a Flash-based memory module. A number of Flash-based memory modules may then be removably mounted in a rack-mountable housing to form unitary Flash-based memory unit.

A combination pressure and vacuum smoker is described that includes separate compartments for the creation of a fire, the pressurized smoking of foods, and the smoking of foods in a partial vacuum. In operation, a user creates a fire in the fire compartment and places the foods to be smoked in the other compartments. The unique design to the device allows a user to pressurize the fire compartment with air and to transfer the pressurized and smoke filled air to the pressure smoking compartment to smoke the foods therein contained under pressure. The design further allows a user to create a partial vacuum within the vacuum smoking compartment, to then draw smoke filled air from the fire compartment into the vacuum smoking compartment, and to maintain a partial vacuum in the vacuum smoking compartment. Such a design allows the user to regulate the temperature, smoke concentration, and pressure within the pressure and vacuum smoking compartments using only the fire contained in the fire box as a source of smoke and heat. The present invention also includes a method for the pressurized and vacuum smoking of foods.
