Abstract: An apparatus and method for fast battery charging are provided. A fast battery charger applies high charging current to a battery to minimize charging time. Micropeak detection of the battery voltage prevents overcharging of the battery cells, thereby preventing degradation of battery capacity over time. Noise reduction throughout the system as well as improved detection resolution allows for micropeak detection. A linear power supply eliminates switch noise. The sampling frequency is synchronized with the power supply, eliminating error due to power supply variation. Sleeping sampling is performed to overcome noise due to operation of the CPU. Improved measurement resolution is obtained via a 10-bit analog to digital converter. A subtraction technique maintains the high measurement resolution.

The wind indicator toy comprises a tail section for catching the wind, a front section for indicating the direction of the wind, a tail mounting section for mounting the tail section, a joinder for joining the tail mounting section with the front section, and a pole upon which the assembly rotates.
Abstract: The present invention discloses a biological sample collection kit which can be utilized to collect samples of biological origin for use in any recovery and identification method. The biological sample collection kit comprises a sterile device for collecting a sample, a collection and dispersing device for depositing and holding the sample, a device for transferring the sample, and a container for storing the sample to be tested. There may also be a labeling system for identifying the sample and for diluting the sample. The biological sample collection kit preferably contains an outer bag which holds, in a sterile environment, all of the items used in the testing procedures. Additionally, a container of collection fluid is preferably included in the sample collection kit.
Abstract: This device discloses a portable sequential contaminant detection system which can test samples for contaminants at predetermined timed intervals. The detection system has a motor to advance a matrix, a motor to raise and lower syringes holding liquefied samples of air to be tested, and a motor to raise and lower plungers within the syringes to draw up fluids or expel fluids into reservoir wells of the matrix to test air or other samples for contaminants. The system relies upon a "matrix" which will hold reagents with which the air samples will be mixed. The matrix is stepped to move into precise registration with the "read" module where the relative reflectance of each capture membrane reads statically by a fixed LED, silicon photodiode and amplifier associated with each channel.

Abstract: A method is provided for forming a molten oxide ceramic electrode for a plasma arc ignited between first and second electrodes within a plasma arc chamber, wherein the conductivity the oxide ceramic is a function of temperature alone. Following ignition of the plasma arc, a mixture is formed of a small quantity of molten oxide ceramic and a sufficiently high concentration of a volatile contaminant to render the mixture electrically conductive. The plasma arc is then transferred from one of the electrodes to the mixture. The temperature of the mixture is raised sufficiently to render the oxide ceramic electrically conductive. Finally, the volatile contaminant is progressively removed from the mixture so as to leave an electrode composed of substantially pure molten oxide ceramic.
