The method of controlling rechargeable battery power is a method that includes limiting the amount of usable power during rechargeable battery charging and discharging, determining a rechargeable battery current-voltage characteristic function based on rechargeable battery charging and discharging current flow and voltage, finding a limiting discharging current I_max and/or a limiting charging current I_min from a prescribed minimum voltage V_min to prevent over-discharging and/or a prescribed maximum voltage V_max to prevent over-charging and their intersection with the current-voltage characteristic function, and controlling current such that discharging current greater than or equal to I_max and/or charging current less than or equal to I_min does not flow through the rechargeable batteries. In this fashion, the amount of usable power can be limited considering factors such as the memory effect, and the rechargeable battery can be used to its maximum capability within the range of safe operation.

The invention further provides for modifications to the above described chromatographic methods that enable the separation of charged molecules exhibiting virtually identical pI's by shifting both the buffer's pKa and the pI's of the eluted charged molecules while they are traversing the ion exchange column.

In a power supply circuit, a main transistor, which transmits power from an input terminal to an output terminal, is controlled so that a detected voltage from an input voltage is consistent with a reference voltage indicating a target voltage. An output current is detected and a limited value of the output current is set so that the limited value increases gradually when the output voltage rises up to the target voltage. The main transistor is controlled so that the output current keeps a value less than or equal to the limited value. This configuration is able to suppress an overshoot of the output voltage, thanks to a gradually raised control of the limited value. Additionally, to avoid the influence of a ringing component of the input voltage, a delay control circuit to give a delay to the start of rise of the output voltage can be provided.

Data on indoor air quality can be obtained using air monitoring stations. Air stations can provide information on odor and chemicals, microscopic airborne particulates, carbon monoxide, relative humidity, temperature and carbon dioxide. This data on indoor air quality, however, does not in itself provide a sufficiently comprehensive picture of indoor air quality. The data can be correlated with an infrared home inspection to facilitate the identification of factors affecting indoor environmental quality in a specific residence. Additionally, data on air quality can be obtained using mold air samples. Additional data on indoor environmental quality can be obtained using a sound pressure level meter to measure sound levels (indoor/outdoor) and temperature changes over time. A report on indoor environmental quality can be provided to a homeowner.

In a current mirror circuit, a compensation resistor having a positive temperature coefficient is connected between the source of a MOS transistor and a power supply line. When the temperature rises, a current output by the constant current circuit and a current flowing through the drain of the MOS transistor decrease. Since the resistance of the compensation resistor increases, however, a voltage between the gate and source of another MOS transistor can be prevented from declining due to the decrease in the drain current so that an electric potential at the gate of a further MOS transistor, hence, a main current, can be prevented from fluctuating. In addition, a constant current output circuit is configured to shunt a feedback control current thereby to adjust an output current of each channel.

(2) An aliphatic diol residue having an average carbon number of 2.0 to 3.0.

A driver circuit uses a feedback loop having a programmable timer and timer logic to adjust a slew rate delay period used to accommodate slewing current when charging or discharging a load capacitor, and to increase the current limit during the slew rate delay period by selecting a larger input current reference value. Increasing the current limit provides for a faster settling time. The value of each input current reference value can be programmed. The programmable timer and the timer logic can be configured to coordinate the slew rate delay period and the selected input current reference value. The slew rate delay period can be adjusted based on which input current reference value is applied.

The card has a limited monetary value, which is advantageous if it is lost or stolen. No connection exists between the card and its owner. As a result, the owner's credit rating cannot be tarnished by actions of a third party.
