The driveline torque spikes may be mitigated with a motor spike torque command generated in response to a wheel acceleration of a wheel of the vehicle exceeding a spike threshold. The motor spike torque command may be configured for controlling an electric motor of the vehicle to mitigate the driveline torque spike in a driveline configured to connect the motor to the wheel.

Abstract: A vehicle driving assistance system is disclosed. The system may include a transceiver configured to receive a source location and a destination location for a user trip, a user driving information and road information associated with a plurality of geographical zones between the source location and the destination location. The system may further include a processor configured to calculate a user driving index based on the user driving information. Further, the processor may be configured to calculate a zone index for each geographical zone based on the road information. The processor may be further configured to correlate the user driving index and the zone index, and calculate a driver assistance index for each geographical zone based on the correlation. The processor may perform a control action when the calculated driver assistance index is greater than a predetermined threshold.

Abstract: A varifocal liquid lens includes a body filled with two different fluids separated by an interface of a variable curvature across a clear aperture of the varifocal liquid lens. At least one of the first or second fluids is birefringent, such that a refractive index difference between the first and second fluids and resulting optical power of the varifocal liquid lens is dependent on polarization of impinging light. At a first light polarization, the first and second fluids may be matched in refractive index, while at a second, orthogonal light polarization, the first and second fluids may be mismatched in refractive index, whereby the first interface between the first and second fluids may have a variable, non-zero optical power for the second polarization while having a substantially non-variable, zero optical power for the first polarization of light.

Abstract: Techniques are described herein that are capable of performing pointer-based sharing of a data structure between threads. A process, including first and second threads, is executed. A first memory system associated with the first thread is created to manage a first memory page that points to a shared array buffer that includes a data structure stored in contiguous memory spaces. A second memory system associated with the second thread is created to manage a second memory page that points to the shared array buffer. The second thread is configured to have access to the data structure in the shared array buffer by causing a pointer, pointing to the data structure, and a size indicator, indicating a size of the data structure, to be sent from the first thread to the second thread. The data structure is capable of being changed without being re-arranged to be contiguous in memory.

Abstract: Methods for operation fragmentation with metadata serialization in query processing pushdowns are performed by systems and devices. A compute node receives a query directed to database data, and generates query text fragments. Portions of metadata of the database are read from different page servers, and are serialized by the compute node. Page identities of data pages in a page server that stores the data are determined from a page index at the compute node, and the compute node provides the text fragments, the serialized metadata, and the page identities to the page server storing the data. The page server compiles the text fragments based on the serialized metadata to generate an executable query plan for the query. The page server initializes and performs execution of the executable query plan against the data as a pushdown query operation, and a result of pushdown query operation is provided to the compute node.

Abstract: An electronic control unit (ECU), or node, is configured to use a single key for all virtual ECUs (V-ECUs) having a message to transmit. The ECU also may include a security peripheral that includes the stored shared key. The security peripheral may further include a policy enabling it to detect if a request from the V-ECU is valid, in which case it generates a MAC. The security peripheral is also used to store information in a MAC Generate Allow List (MGAL), which may define the policy about when the V-ECU can transmit. The ECU may include a crypto-engine, which stores shared keys from other nodes used to verify MACs transmitted by other nodes.

Abstract: To track an object with radar, and achieve greater than range resolution precision, the phase of a difference signal can be utilized and adjusted as the tracked object crosses between resolution ranges. Changes in the object's distance can be detected with greater than range resolution precision by utilizing the phase. Such changes can iteratively inform the determined distance across multiple phase cycles within a single distance range. As the movement of the object approaches, and then crosses, between resolution ranges, the phase as determined within an origin resolution range can be compared with a coincident phase within the destination resolution range and the difference can then be utilized to adjust the phase as the object then remains within the destination resolution range. Such phase adjustments can be applied across multiple resolution ranges, allowing for the tracking of an object, utilizing radar, while achieving greater than range resolution precision.

Abstract: A network packet can be received at a host and it can be determined if such packet has a valid cryptographic public key for a destination host. If there is no known valid cryptographic public key, it is determined whether the network packet is a first network packet sent to the destination host, and if so, a queue is designated for network packets addressed to the destination host and a key management server is queried for a valid cryptographic public key associated with the destination host. Otherwise, the network packet is placed in a queue designated for the destination host until a valid cryptographic public key associated with the destination host becomes available. Upon a valid cryptographic public key associated with the destination host becoming available, the network packet is processed, encrypted and sent to the destination host.
