  • Patent number: 9425808
    Abstract: A frequency detection technique includes generating first and second signals such that a frequency of the first signal is the same as a frequency of the second signal and such that the second signal is phase-shifted by a fixed amount with respect to the first signal. The technique further includes generating a third signal having a frequency that corresponds to an absolute value of a difference between the frequency of the first signal and an integer multiple of a frequency of the reference signal. The technique further includes generating a fourth signal having a frequency that corresponds to an absolute value of a difference between the frequency of the second signal and an integer multiple of the frequency of the reference signal. The technique further includes generating an fifth signal indicative of whether a phase relationship between the third and fourth signals is a leading phase relationship, a lagging phase relationship, or an in-phase relationship.

  • Patent number: 9312400
    Abstract: Techniques are described to harvest power from a single current carrying conductor to furnish power to a powered device. The techniques employ a power harvesting device that is coupled to the conductor. In implementations, the conductor has a first path and a second path. The power harvesting device includes a first switch coupled to the second path. An energy storing element is coupled to the first path and configured to store energy based upon the direct current flowing through the first path. The power harvesting device also includes a power condition and management device coupled to the energy storing element configured to switch the first switch to a closed configuration when the energy storing element is measured to have a predefined high voltage threshold, and to switch the first switch to an open configuration when the energy storing element is measured to have a predefined low voltage threshold.

  • Patent number: 9240900
    Abstract: Conventional routers employ a wired backplane that employs “long reach” serializer/deserializer (SerDes) links, but this type of architecture is complicated, costly, and uses a considerable amount of power. To address some of these issues, a new wireless backplane architecture is provided here. This wireless backplane employs direct millimeter wave links between line cards that replaces the convention, wired switching fabric.

  • Patent number: 9157966
    Abstract: An online method and apparatus for determining state of charge (SoC) and state of health (SoH) of batteries on platforms that present dynamic charge and discharge environments is disclosed. A rested open circuit voltage (OCV) may be estimated online using a battery dynamic model along with measured terminal voltage, current and temperature. The SoC and SoH can then be determined from this estimated OCV. The apparatus and methods may estimate SoC and SoH of a battery in a real-time fashion without the need to a) disconnect the battery system from service; b) wait for a predefined rest time; or c) depolarize the battery.

  • Patent number: 9151793
    Abstract: The method for measuring the complex dielectric constant of a substance is based on calculations made in the frequency domain. An open ended rectangular waveguide terminates, at one end, in a non-resonant rectangular cavity, which is then filled with a substance of interest. An electromagnetic wave of known frequency is transmitted through the waveguide and the reflection coefficient at the interface between the waveguide and the cavity is measured by a network analyzer or the like. Another measurement is then made with a slight variation in depth of the cavity or a variation in frequency, and from these two measurements of the reflection coefficient, the complex dielectric constant of the substance of interest can be calculated.

  • Patent number: 9023211
    Abstract: A VMD system and method uses an aspirator to generate a vacuum pressure for drawing permeate from a membrane module. The aspirator generates the vacuum pressure by receiving and passing a circulating liquid and combines the permeate with the circulating liquid such that the permeate condensates in the circulating liquid. Using an aspirator (e.g., instead of a vacuum pump) allows a more efficient and cost-effective operation of the VMD system and method, particularly in a desalination application. A VMD system and method using an aspirator may be used in desalination and other applications including, without limitation, environmental cleanup (e.g., removal of volatile organic chemicals from water) and food and medical applications.
