  • Publication number: 20220298508
    Abstract: Provided herein are oligonucleotide agents comprising one or more therapeutic oligonucleotides such as siRNA and one or more targeting conjugate compounds. In certain embodiments, the conjugate compound comprises one or more N-Acetylgalactosamine as targeting group, branching group and linker group. By incorporating long carbon chains into the GalNAc clusters instead of using multiple amide groups to elongate the chain length, simplification of the synthesis by reducing the number of steps is achieved.

  • Patent number: 10904938
    Abstract: A telematics controller is programmed identify a location of the vehicle responsive to failure of a vehicle-originated data call to initiate packet-switched communications, and send, to a service delivery network configured to provide data services to the vehicle, a message specifying that circuit-switched communication but not packet-switched communication is available to the vehicle. A message is received, over a wide-area network from a vehicle, in response to a failed initiation of a packed-switched data connection over the wide-area network, indicating that packet-switched communications are unavailable at a current location of the vehicle. Failure zones are updated to indicate that the current location of the vehicle is a network location supporting circuit-switched communication but not packet-switched communication over the wide-area network.

  • Patent number: 10424970
    Abstract: A control scheme and architecture for a wireless electrical energy transmission circuit employs two solid-state switches and a zero voltage switching (ZVS) topology to power an antenna network. The switches drive the antenna network at its resonant frequency and simultaneously energize a separate resonant circuit that has a resonant frequency lower than the antenna circuit. The resonant circuit creates out of phase voltage and current waveforms that enable the switches to operate with (ZVS).
