摘要： This invention is related to a deep multi-sensor fusion system for inter-radar interference-free environmental perception comprising of (1) polystatic Multi-Input Multi-Output (MIMO) radars such as radio frequency radar and laser radar; (2) vehicle self-localization and navigation; (3) the Internet of Vehicles (IoV) including Vehicle-to-Vehicle communication (V2V), Vehicle-to-Infrastructure communication (V2I), other communication systems, data center/cloud; (4) passive sensors such as EOIR, and (5) deep multi-sensor fusion algorithms. The self-localization sensors and V2X formulate cooperative sensors. The polystatic MIMO radar on each vehicle utilizes both its own transmitted radar signals and ones from other vehicles to detect obstacles. The transmitted radar signals from other vehicles are not considered as interference or uselessness as conventional radars, but considered as useful signals to formulate a polystatic MIMO radar which can overcome the interference problem and improve the radar performance. This invention can be applied to all kinds of vehicles and robotics.

摘要： A method for maintaining traffic continuity through a Traffic Offload Function (TOF) entity includes the following steps: the TOF entity receives a downlink packet of offload traffic of a User Equipment (UE), where the downlink packet of the offload traffic is sent by a Packet Data Network (PDN); the TOF entity sends a Core Network (CN) paging message to the UE; the TOF entity receives a paging response sent by the UE to the CN, where the paging response includes a service request message of the UE; and the TOF entity forwards the service request message to the CN so that the CN sets up a Radio Access Bearer (RAB) after the service request message is received. With the method, the communication between the CN and the UE can be restored to guarantee the transmission of traffic. Accordingly, a TOF entity is also disclosed according to the present invention.

摘要： Replay-time-only functionalities in a computer program are executed only during replay in a virtual machine and are skipped outside of replay. If a replay-time-only functionality is detected during the replay of a program execution in a virtual machine, the replay may be paused and the virtual machine state may be saved. The replay-time-only core functionality is executed. When this execution is complete, a prior state of the virtual machine may be restored and the replay may be resumed.

摘要： A method for precisely counting guest branch instructions in a virtualized computer system is described. In one embodiment, guest instructions execute in a direct execution mode of the virtualized computer system. The direct execution mode operates at a first privilege level having a lower privilege than a second privilege level. A branch count of previously executed first privilege level branch instructions is maintained as instructions execute. Execution of a first privilege level branch instruction caused by a control transfer to the direct execution mode is detected. Responsive to the detection, a guest branch instruction count is determined based on the first privilege level branch count.

摘要： An ultra-low power crystal oscillator architecture that draws less than 2 μA during steady state operation. An amplifier stage is self biased and has input and output clamp circuits that limit its signal swing. Circuit values are selected such that there is sufficient transient load current for the first amplifier stage to oscillate, while at the same time the input and output clamp circuits maintain a sufficiently low swing of the stage such that the steady state average load current is on the order of less than 1 μA.
