  • Publication number: 20210373010
    Abstract: Systems, methods, and apparatus are disclosed for determining quantitative hormone and chemical analyte results from qualitative test results. An image is taken of an ovulation test device. The image is analyzed to identify a color intensity ratio (T/C ratio) between a color density of a test-line to a color density of a control-line. Additionally, a quantitative substance level may be determined using the T/C ratio, by identifying the type of test device and referencing a data structure that relates quantitative substance levels to T/C ratios for the identified type of test device.

  • Patent number: 10905145
    Abstract: An enhanced sweetener made from granules of a carrier, such as sucrose, embedded with molecules of a high potency sweetener, such as stevia extract. The process for making the enhanced sweetener involves dissolving the high potency sweetener in warmed water and mixing the resulting solution with the heated carrier. The resulting slurry is then dried, optionally under reduced pressure. The apparatus for producing the enhanced sweetener includes one or more heated agitators connected to a heated, airtight blender, which can be evacuated with a vacuum pump. The result is an enhanced sweetener with a homogenous distribution of high potency ingredients that retains the functionalities of sugar necessary for food preparation, improves the spreading of the sweetness throughout the food, and reduces aftertastes. Other high potency ingredients and carriers may also be used in the process.

  • Patent number: 9146826
    Abstract: Embodiments disclosed herein enable network simulation including a range of networking technologies to be scaled to include large numbers of devices under test (DUTs) even though computing resources, such as a total number of simulation hosts or IP addresses, may be limited. By enabling a network simulator to scale with limited computing resources, developers may be enabled to reduce the requirements for physical space, power, cost, and maintenance for network simulation. For example, developers may be able to determine capacity, such as a total number of DUTs that a network management system (NMS) is capable of managing, even though few simulation hosts or IP addresses may be available for simulation of the DUTs.

  • Patent number: 9106498
    Abstract: A method for symbol synchronization of received digital signal and a digital signal reception apparatus are provided. The method comprises steps of correlating the received digital signal with the received signal delayed by one symbol so as to obtain a first correlation value result as a combined effort of a strongest path and other paths; removing substantially effect of the strongest path from the first correlation result so as to obtain a second correlation result which exhibits contribution of a fastest path; searching a maximum correlation value and its position of the fastest path so as to determine symbol synchronization timing for initiating FFT processing. The digital signal reception apparatus is characterized by a symbol timing detecting unit for determining symbol synchronization timing of the fastest path through substantially removing the effect of a strongest path.

  • Patent number: 9036694
    Abstract: A cable transmitter supports a number of low density parity check (LDPC) coding rates, e.g., ¼, ?, ?, ½, ?, ?, ¾, ?, ?, 8/9 and 9/10; and supports a number of quadrature amplitude modulation (QAM) schemes, e.g., 4-QAM, 16-QAM, 64-QAM, 256-QAM, 1024-QAM or higher. For a selected modulation scheme, the cable transmitter selects between using a non-uniform symbol constellation or a uniform symbol constellation as a function of a selected coding rate.

  • Patent number: 9026878
    Abstract: A fast retransmission method by introducing the internal node under better channel condition to join the work of retransmission after the destination node sends out the packet loss indication for unicast services. Extended to serve multicast services, a system comprising a plurality of nodes utilizes the farthest node in each branch from the source to transmit an acknowledge signal when packet loss occurs. The system then enables the closest node to the acknowledging node to retransmit the requested packet, thereby improving the target packet hit rate and data integrity with less retransmission steps.

  • Publication number: 20150081420
    Abstract: A computer-implemented method for identifying relationships between online content items uses a computing device including a processor and a memory. The method includes identifying a first content item and identifying a plurality of occurrence results for the first content item. Each occurrence result of the plurality of occurrence results includes an indicator that the first content item was retrieved along with a list of other content items based on an online activity of at least one user device. The method also includes computing a number of co-occurrence events involving the first content item and a second content item from the plurality of occurrence results. Each co-occurrence event includes an indicator that both first content item and second content item were retrieved together in an occurrence result. The method further includes computing a relationship value between first content item and second content item using at least the number of co-occurrence events.
