  • Temperature control strategy for electric starter system with polyphase brushless starter motor
    Patent number: 10487791
    Abstract: An electric starter system is usable with a powertrain having an engine with a flywheel. The starter system includes a brushless starter motor having a machine temperature, and a solenoid operable for translating a pinion gear into meshed engagement with the flywheel and the starter motor in response to a requested engine start event. A controller has temperature regulation logic that includes a proportional-integral torque control loop. Execution of a method embodied by the logic, in response to the requested engine start event when the machine temperature exceeds a first temperature, causes the controller to determine a required starting torque of the starter motor using the control loop. The controller causes the starter motor to transmit the required starting torque to the engine at a level that reduces the machine temperature below the first temperature.

  • Automated systems and methods for providing bidirectional parallel language recognition and translation processing with machine speech production for two users simultaneously to enable gapless interactive conversational communication
    Publication number: 20190354592
    Abstract: A novel system and multi-device invention that provide a means to communicate in real-time (conversationally) between two or more individuals, regardless of each individual's preferred or limited mode of transmission or receipt (by gesture, by voice—in Mandarin to German to Farsi, by text in any major language, and via machine learning, eventually by dialect). Systems and methods for conversational communication between two individuals using multiple language modes (e.g. visual language and verbal language) through the use of a worn device (for hands-free language input capability) are provided. Information may be stored in memory regarding user preferences, as well as various language databases—visual to verbal to textural- or the system can determine and adapt to user (primary and second) preferences and modes based on direct input, and adapt.

  • PARTICLE COLLECTOR
    Publication number: 20190353564
    Abstract: Aspects of the disclosure are directed to apparatuses and methods involving particulate sampling. As may be consistent with one or more embodiments, an apparatus includes a flow direction structure, a flow sampler and a particle collector having a collecting surface. The flow direction structure has interior sidewalls that direct the flow of particulate-laden gas along a flow path. The flow sampler is located in the flow path within the interior sidewalls, and operates with the flow direction structure to sample a portion of the particulate-laden gas at a reduced velocity, while allowing another portion of the particulate-laden gas to exhaust around the flow sampler. The flow sampler operates with the particle collector to direct the sampled portion of the particulate-laden gas to the collecting surface, and to adhere particulates from the particulate-laden gas to the collecting surface.

  • METHOD AND APPARATUS FOR MAINTAINING UPLINK SYNCHRONIZATION AND REDUCING BATTERY POWER CONSUMPTION
    Publication number: 20190357167
    Abstract: A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

  • DISCOVERY AND NETWORK ACCESS PROCEDURES FOR 5G THINGS COMMUNICATION SYSTEM
    Publication number: 20190357123
    Abstract: Systems and methods of providing communications between UEs are generally described. A notification resource indicating subsequent transmission of a discovery message is transmitted from a UE to another UE using a discovery ID selected from a limited number of discovery IDs stored in the other UE. The other UE transmits a random access request to the UE having a temporary ID. The UE may not respond if the temporary ID is already used or may transmit data transmission information scrambled by the temporary ID. The other UE transmits a contention resolution PDU to the UE and may receive an ACK to indicate ID contention is not present, or either no response or a NACK to indicate the presence of ID contention. The other UE may either select a new temporary ID or use a backoff timer to retransmit the random access request at a random time.
