  • Publication number: 20220095247
    Abstract: Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include auxiliary information. The auxiliary information may be associated with one or more symbols of the preamble. The auxiliary information may contain power boost information.

  • Publication number: 20220094581
    Abstract: An OFDM communication system is described that allows different values of D in a single domain where nodes are operating in different portions of frequency bands. For the power-line medium, G.9960 has defined two overlapped baseband bandplans, 50 MHz-PB and 100 MHz-PB. In this exemplary scenario, the level of frequency diversity is different depending on the bandplan, hence providing different header decodibility if D is fixed to 1. If D is fixed to 2, then it increases reliability for the narrowband devices, but may also unnecessarily increase overhead for the wide-band devices. An exemplary aspect is therefore directed to techniques to accommodate different repetitions schemes (D=1, . . . , DMAX and H=1, . . . , HMAX) in a single domain, and still allow devices to communicate with one another where DMAX and HMAX can be larger than 2.

  • Publication number: 20210399365
    Abstract: The present invention relates to a cathode material for a lithium-air battery and a method of manufacturing a cathode using the same. The cathode material of the present invention includes a solvent component and thus includes an electrolyte in a small amount compared to a conventional cathode material, thereby reducing the weight of a cathode manufactured using the cathode material, ultimately increasing the energy density of a lithium-air battery including the cathode.

  • Publication number: 20210333199
    Abstract: The present disclosure relates to a ferrocene-based compound having high selectivity for sulfide ion. The ferrocene-based compound is obtained by reacting a ferrocene starting material with one or more organic compound selected from a nitrile, a methyl ester and an ethyl ester, and a chemical sensor in solution state is prepared by mixing the compound with an organic solvent. The chemical sensor according to the present disclosure has high selectivity and sensitivity for sulfide ion even at low concentration and may be used as a chemical sensor for detecting hydrogen sulfide in solution state by allowing visual inspection of sulfide ion.

  • Patent number: 10917272
    Abstract: A non-transitory computer-readable information storage media for use within a wireless OFDM network that causes to be transmitted or received a first packet type and a second packet type. The first packet type has a header field with two parts with each part comprising a different set of header bits. The two parts of the header field are transmitted or received using two OFDM symbols. The second packet type has a header field with four parts with the first and second parts comprising the same first set of header bits and the third and the fourth part comprising the same second set of header bits. The four parts of the header field are transmitted or received using four OFDM symbols. The second packet type provides more reliable transmission or reception than the first packet type.
