  • Publication number: 20210193994
    Abstract: Particulate carbon-coated lithium metal phosphate materials are provided with a copper content less than or equal to 1 ppm. Methods of making such materials are also provided, the methods involving the use of adsorbent materials comprising 2-aminomethylpyridine functional groups to remove copper from iron (II) precursors used in the formation of lithium metal phosphates.

  • Publication number: 20200255297
    Abstract: A method for synthesizing mesoporous silica microparticles comprising the steps of: preparing a sol from an ammonium catalyzed hydrolysis and condensation reaction of a pre-sol solution comprising a silica precursor and a structure directing agent dissolved in a mixed solvent system comprising an alcohol and water to produce mesoporous particles of silica with an average diameter of up to about 50 ?m; hydrothermally treating the particles to increase the pore size; treating the particles to remove residual structure directing agent; and further increasing the pore size using controlled dissolution.

  • Patent number: 5444695
    Abstract: A token ring local area network (LAN) testing apparatus is provided. The apparatus monitors history or status of token ring stations. Such information is useful in isolating token ring faults that may occur during its operation. The apparatus includes current and past memory lists that contain status information for each token ring station. The current station memory list contains addresses of all token ring stations that are present during a current neighbor notification process. The last station memory list contains addresses of all token ring stations that were present in the token ring during the neighbor notification process that was previous to the current neighbor notification process. A neighbor notification process is a conventional part of the token ring media access control (MAC) protocol. Included with the addresses in these lists is a determined one of a number of state characters that is indicative of station status.

  • Patent number: 5425017
    Abstract: A testing apparatus for token ring local area networks (LANs) which can insert into the token ring network without requiring a separate port on a media access unit (MAU). The testing apparatus of the present invention is connected between a regular network station and the MAU. The testing apparatus is insertable into the network through the MAU, and the regular network station is able to insert into the network through the testing apparatus. Once inserted, the regular network station and the testing apparatus act as separate stations in series on the LAN. Due to its central position in this configuration, the testing apparatus is able to test for possible faults that might be present in the network and/or in the station to which it is connected. In addition, since the testing apparatus does not require a separate port on the MAU, no active user on the network needs to be disconnected for any extended period of time.

  • Patent number: 5365513
    Abstract: A token ring local area network (LAN) testing apparatus is provided. The apparatus includes hardware and software that enables it to determine whether the testing apparatus is able to send frames into the token ring at a correct ring speed. The apparatus includes a conventional network interface card (NIC). The NIC includes two selectable clock signals, with the frequencies of the two clock signals being different. When the NIC is used in transmitting frames into the token ring, one of the two clock signals is selected to accompany the frames. The testing apparatus monitors whether frames and/or tokens are obtained from the token ring using the selected clock signal. If not, the testing apparatus causes the other clock signal to be selected. A determination of proper ring speed is made before a beacon condition occurs that would disrupt normal operation of the token ring.

  • Patent number: 5309428
    Abstract: A token ring local area network (LAN) testing apparatus is provided. The apparatus is able to conduct a phase jitter measurement without disruption of normal token ring operation. The apparatus transmits a frame that includes phase jitter test data. This frame is transmitted into the token ring, together with a clock signal. After return of the frame with the phase jitter test data, a comparison is made between the recovered clock signal accompanying this frame and a reference clock signal. The result of this comparison provides a sample used in determining phase jitter. In making the measurement, an interpolation circuit is utilized to increase the resolution of the time difference between the recovered clock signal and the reference clock signal. A clamp circuit is used to ensure that each interpolation begins at the same reference voltage, as well as ensuring that the interpolation process is properly discontinued.
