US Classification:

208289, 525379, 5253337, 196 46

Abstract:

The present invention provides a method for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process and adding an antifouling agent containing a polymer base unit and a polyamine group to the crude hydrocarbon. The antifouling agent can be obtained by reacting an epoxidation reagent with a vinyl-terminated polymer, such as polypropylene or poly(ethylene-co-propylene), to form a terminal epoxy group, followed by reacting a polyamine with the epoxy group.

US Classification:

208289, 564138, 564204, 564192, 196 46

Abstract:

Methods and systems for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process and adding an antifouling agent containing a polymer base unit and a polyamine group to the crude hydrocarbon are provided. The antifouling agent can be obtained by converting a vinyl terminated polymer, such as polypropylene or poly(ethylene-co-propylene), to a terminal acyl containing functional group, followed by reacting the terminal acyl containing functional group with a polyamine compound.

International Classification:

G08G 1/16
G08G 1/0967

Abstract:

A user equipment (UE) in a vehicle, or a road side unit, may broadcast an inter-vehicle message for a driving maneuver to be executed by the vehicle. The inter-vehicle message may be a coordinated driving maneuver request requiring acceptance from another vehicle or an informational message for the intended driving maneuver. The inter-vehicle message includes a temporal execution window defining a range of time during which the driving maneuver will be initiated. A temporal window defining a range of time during which the driving maneuver will be completed may also be included. A spatial window defining a range of distance for a start and/or stop location for the driving maneuver may also be completed. The vehicle may execute the driving maneuver within the temporal execution window, e.g., if a driving maneuver response is received before the expiration of the temporal execution window, and will otherwise cancel the driving maneuver.

International Classification:

H04B 7/185
H04W 76/11

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may receive, from a relay node via a radio access link, information indicating a link layer identifier of the relay node associated with a relay service, wherein the relay node is associated with a radio access identifier. The network entity may configure a relay service with the relay node and a remote node using a mapping between the radio access identifier and the link layer identifier. Numerous other aspects are described.

International Classification:

G01S 5/02
H04W 4/02
H04W 72/04
H04W 4/06
H04L 5/00

Abstract:

Methods, systems, and devices for wireless communication are described. An initiator user equipment (UE) may broadcast, via a sidelink connection to a set of target UEs, a group sidelink communication request that includes a sidelink ranging service identifier. The group sidelink communication request may further include a broadcast identifier or a groupcast identifier. The initiator UE may establish, via the sidelink connection, a set of unicast sidelink sessions with the set of target UEs. some examples, the initiator UE may transmit, via the sidelink connection, a set of position reference signal requests via the set of unicast sidelink sessions to initiate a set of sidelink ranging sessions. The initiator UE may then receive, via the sidelink connection, a set of position reference signal responses from the set of target UEs during each of the plurality of sidelink ranging sessions.

H04W 76/15
H04L 5/00

Abstract:

Methods, systems, and devices for wireless communications are described. In a wireless communications system, one or more user equipments (UEs) may implement distance-limited sidelink-based ranging techniques. An initiating UE may transmit one or more positioning reference signal (PRS) request messages to one or more target UEs via a sidelink channel. In some cases, the initiating UE may receive one or more response messages from at least one target UE that is located within a threshold distance from the initiating UE. In some examples, based on receiving the one or more response messages, the initiating UE may transmit PRSs to each target UE that transmitted a response message.

International Classification:

H04W 64/00
H04W 24/10
H04L 5/00

Abstract:

Certain aspects of the present disclosure provide techniques for sensing window configuration for sidelink based ranging and positioning. For example, during sidelink-based ranging or sensing, a user equipment (UE) may determine the relative distance or position with other UEs. This may be realized by a UE broadcasting a wideband position reference signal (PRS) on an unlicensed band and measuring the round-trip time associated with a peer UE's PRS. The measurement accounts for a PRS transmission time transmitted by each UE. The UE may apply a sensing window to determine whether a neighboring UE has reserved PRS transmission times. The present disclosure provides methods and techniques for a network entity to configure a sensing window in a UE so that the UE may determine, during the sensing window, whether neighboring UEs have reserved a PRS transmission time.
