    Abstract: Embodiments relate to systems and methods for electronically conditioning transmission of communications based on results of a connection assessment. An electronic file is executed at an electronic device, which causes a first query and a second query to be presented. A first query response and a second query response are identified. The first query response is stored in a locked configuration that inhibits the ability to modify the first query response to the first query. The second query response is stored but is not stored in the locked configuration. Query response data is generated that includes an identifier of the second query, an identifier of the second query response and an identifier of the electronic device. A connection variable is determined by assessing one or more network connections available to the electronic device. When a transmission condition is satisfied, the query response data is transmitted to another device.

    Abstract: Determination of one or more timing (phase) and/or frequency corrections to be made to a local time base of a receiver device to synchronize the local time base with the time of GPS or other highly accurate time base. Timing packets from one or more grandmaster devices whose time bases are substantially the same as that of GPS or the like and/or positioning system signals (e.g., GPS signals) directly from a positioning system are received and manipulated to determine the timing and/or frequency corrections. The corrected time base may be used to assist in acquiring such positioning signals to allow for higher accuracy correction and/or for downstream communication operation. The present utilities are advantageous such as when a sufficient number of channels (e.g., four) from the receiver device to positioning system satellites are unavailable to synchronize the local time base to the GPS or other accurate time base.

    Abstract: A distributed control information system for three party communications in a Vehicle to Everything (V2X) environment is disclosed. A first node can generate sidelink control information for a transmission between a second node and a third node. The first node can transmit the sidelink control information to the second node, and then the second node can transmit a portion of the sidelink control information relevant to the third node to the third node. In an embodiment, the first node can also send the third node portion of the sidelink control information to the third node directly, thus improving the reliability of the system. These transmissions can be performed via sidelink communications channels.

  • Patent number: 11283559
    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to schedule individual orthogonal frequency-division multiple access (OFDMA) resources on an upstream channel to serve a data transmission request from a downstream device. A schedule for a set of available resources on the upstream channel to serve the data transmission request is generated, based on a dynamic bit loading profile, including generating data indicative of a first bit loading profile for a first set of resources from the set of available resources for a first burst, and data indicative of a second bit loading profile for a second set of resources from the set of available resources for a second burst. The schedule is transmitted to a downstream device, such that the downstream device is configured to encode the first burst using the first bit loading profile and the second burst using the second bit loading profile.

  • Patent number: 11265096
    Abstract: In a transceiver, the accuracy of a packet time stamp can be improved by compensating for errors introduced by processing of the packet. A received packet can be received via multiple lanes. A packet time stamp can be measured using a start of frame delimiter (SFD). A last arriving lane can be used to provide a recovered clock signal. A phase offset between the recovered clock signal and the system clock of the transceiver can be used to adjust the time stamp. A position of the SFD within a data block can be used to adjust the time stamp. A position of the data block within a combined group of data blocks can be used to adjust the time stamp. Also, a serializer-deserializer delay associated with the last arriving lane can be used to adjust the time stamp.

  • Patent number: 11252687
    Abstract: A method of synchronizing signals is disclosed. The method comprises using a clock tracking system to convert a future event target time specified in a time base of a master device into the local unsynchronized time bases of one or more slave devices. Each of the slave devices then generates an event signal at the converted time, such that a coordinated delivery of synchronized signals is achieved.

A super structure grating is used as a reflector structure, and a suspended structure is formed around a region in which the super structure grating is located, to implement, using the suspended structure, thermal isolation around the region in which the super structure grating is located, and increase thermal resistance, such that less heat is lost, and heat is concentrated in the region in which the super structure grating is located, thereby improving thermal tuning efficiency of the reflector structure. Moreover, lateral support structures are disposed on two sides of the suspended structure, to provide a mechanical support for the suspended structure. In addition, regions in the super structure grating that correspond to any two lateral support structures on a same side of the suspended structure fall at different locations in a spatial period of the super structure grating.
