  • Publication number: 20110248567
    Abstract: A charging system of the present invention is connectable to a power grid having a monitoring device. The monitoring device monitors the power delivered to a plurality of loads and determines a power factor and a power factor correction value associated with the loads. The power factor correction value indicates the difference between the power factor and unity. The charging system includes an electrical device, a charger in communication with the electrical device, a charging controller, a power factor correction circuit, a communication device, and a controller. The communication device of the charger receives a data signal from the monitoring device indicative of the power factor correction value associated with the plurality of loads. The power factor correction circuit is configured to communicate an input current to and from the power grid, which adjusts the power factor of the associated loads to about unity.

  • Patent number: 7323993
    Abstract: An RFID antenna is fabricated according to varying current density requirements of different regions of the antenna. A method such as computer modeling is used to determine the current densities of the antenna regions. In one aspect of the invention, a conductive material is printed to a substrate at varying thickness according to current density requirements of particular antenna regions. In another aspect of the invention, materials of different conductivity are printed to the substrate according to the current density requirements. A material of higher conductivity is printed at an antenna region that requires high current density, and a material of lower conductivity is printed at antenna region that requires lower current density.

  • Publication number: 20060017590
    Abstract: Encoding bits includes receiving a bit set to encode. An encoding lookup table associates correlithm objects of a space with bit sets. The space refers to an N-dimensional space, a correlithm object refers to a point of the space. The correlithm object corresponding to the received bit set is identified. The received bit set is encoded as the identified correlithm object. The identified correlithm object is imposed to encode the received bit set and subsequently decoded with table lookup using the reverse process.

    Abstract: A system for identifying relationships between database records includes a memory operable to store a plurality of records comprising a first record and at least one second record. Each record comprises at least one of a plurality of tokens. The system also includes one or more processors collectively operable to determine a weight associated with each of the tokens, compare at least one second record to the first record, and determine at least one relationship indicator based on the comparison and at least one of the weights. The at least one relationship indicator identifies a level of relationship between the first record and at least one second record.

  • Publication number: 20050203947
    Abstract: Manipulating correlithm objects includes establishing correlithm objects of an N-dimensional space, where a correlithm object is a point of the space. The correlithm objects are imposed on the space to yield a combined point. An imposed correlithm object is compared to the combined point. The imposed correlithm object is recovered in accordance with the comparison.

  • Publication number: 20020197631
    Abstract: Devices and methods are described for homogenization, processing, detection, and analysis of biological samples such as insects, fungi, bacteria, and plant and animal tissues. Multiple chambers in these devices permit different processing functions to be carried out at each stage, such that the resulting homogenized product can be further processed, purified, analyzed, and/or biomolecules such as metabolites, proteins and nucleic acids, or pharmaceutical products can be detected. The device can be used in a hydrostatic pressure apparatus, in which different activities, i.e. incubations, addition or renewal of reagent, and generation and detection of signal can be carried out in the appropriate chamber. The method improves the preservation of biomolecules from chemical and enzymatic degradation relative to conventional means. Additionally, this method enables automated sample preparation and analytical processes.

  • Patent number: 5967893
    Abstract: A method for ordering all of the possible hands into a particular sequence is presented. Due to the particular manner in which the hands are ordered and sequenced, any one of the hands can be accessed fairly quickly by the methods provided herein which simplifies complex calculations to table look-up operations. Given a particular hand (the first five cards given to the player in a five-card draw poker), all of the possible hands arising from the particular hand (as a result of the number of cards kept by the player) is iterated and the types of all possible resulting hands tabulated. The combination of hands resulting from the number of cards kept is considered in the iteration. After the iteration is completed, the results obtained is a tabulation of each combination of hands obtained.

  • Patent number: 5958243
    Abstract: A membrane filtration system which uses pump speed controllers to control flow rate and pressure during both the filtration cycle and the backwash cycle. The pump speed controllers operate by changing the frequency of AC current delivered to the pump motors, which changes the flow rate by changing the speed of the pump motor. The speed controllers operate by modulating the pump input power frequency in response to a signal from a flow or pressure signal received from a flow or pressure meter located on a liquid input pipe. This pump speed control method avoids the cyclical dampening patterns observed when trying to adjust pressure and/or flow rates by adjusting regulating valves. The system can also reduce or prevent formation of pressure spikes when switching from a filtration cycle to a backwash cycle, and vice versa. This reduces the likelihood of damage to the membrane from hydraulic pressure pulses.

  • Patent number: 5665907
    Abstract: An ultrasonic method and system are provided for monitoring a fabric to identify a defect. A plurality of ultrasonic transmitters generate ultrasonic waves relative to the fabric. An ultrasonic receiver means responsive to the generated ultrasonic waves from the transmitters receives ultrasonic waves coupled through the fabric and generates a signal. An integrated peak value of the generated signal is applied to a digital signal processor and is digitized. The digitized signal is processed to identify a defect in the fabric. The digitized signal processing includes a median value filtering step to filter out high frequency noise. Then a mean value and standard deviation of the median value filtered signal is calculated. The calculated mean value and standard deviation are compared with predetermined threshold values to identify a defect in the fabric.
