  • Patent number: 9674661
    Abstract: Techniques for generating a real-time 3D position of one device relative another device are described herein. In one embodiment, a first device may be equipped with one or more transmitters and receivers to collect location information based on direct localized signal transmission between the first device and a second device. The first device may also be equipped with an accelerometer and/or digital compasses to assist in resolving ambiguous locations when the first device and the second device are not at an alignment position. Each device may transmit part or all of its collected location information to another device to assist in obtaining the relative location. Alternatively, a separate server may receive the location information from the devices and calculate the relative location of each device based on the received location information.

  • Publication number: 20170077557
    Abstract: The present invention relates to a preparation method of ionic liquids, particularly to a one-step reaction method used for synthesizing quaternary ammonium compounds or quaternary phosphonium compounds. In the method, a nitrogenous or phosphorous compound, a proton compound, and a carbonate ester are added into a reactor simultaneously to synthesize corresponding the quaternary ammonium ionic liquid or the quaternary phosphonium ionic liquid through said one-step reaction, i.e., ‘one-pot method’ reaction, during which three reactants are involved. The present invention also provides a lithium ion secondary battery comprising the ionic liquid prepared by above-mentioned preparation method. The ionic liquid preparation method of the present invention can widen the choice range of raw materials needed when preparing ionic liquids, and further widen the synthesized ionic liquid species.

  • Patent number: 9365596
    Abstract: A two-step pathway for preparing high pure quaternary phosphonium salts is disclosed. In the first step, hydrogen phosphide (PH3) or a higher phosphine reacts with a protonic compound to produce a phosphonium salt, which then reacts with a carbonic acid diester to produce a quaternary phosphonium salt in the second step. On one hand, hydrogen phosphide (PH3) and higher phosphines, including primary phosphines, secondary phosphines, and tertiary phosphines, after neutralization with protonic compound, become sufficiently reactive and can be alkylated by carbonic acid diester to form quaternary phosphonium cations. On the other hand, as an anion-exchange procedure is completely avoided, the process not only gives quaternary phosphonium salts of high purity, but also gives people freedom to design the cation and the anion of a quaternary phosphonium salt synchronously by choosing a preferred phosphine and a protonic compound that can supply a desired anion.
