Expressly turning tracing on and off at each juncture between code that a developer wants to have traced and other code may reduce trace file size but adds computational cost. Described technologies support selectively tracing a process's execution, with some extra tracing done beyond the code the developer wanted traced, but with significantly reduced computational cost, by reducing the number of trace enablement and disablement operations. A trace controller uses a tracing disablement distance variable whose values indicate the computational distance from trace disablement. A distance variable modifier automatically moves the distance variable closer to a stop-tracing value as the process executes. The amount of extra tracing is balanced against the reduction in trace enablement/disablement operations by tuning thresholds, based on information about routine size and computational cost. Operation of the trace controller is illustrated by sample APIs, a tracing state diagram, and a side-by-side comparison, among other items.

Many computing systems process data organized in a matrix format. For example, artificial neural networks (ANNs) perform numerous computations on data organized into matrices using conventional matrix arithmetic operations.

A multiple (e.g. two, three, four, etc.) axial splitting of foci in the interferometric object arm is performed using a multifocal (e.g. bifocal, trifocal, quattro-focal, etc.) optical component, forming thereby at least two, three or even several groups of chromatically split foci in the depth direction. The multifocal optical component is made of a diffractive optical element (712) and a Schwarzschild objective (5). At least two, three, four or even more differently colored foci of different groups of foci coincide in at least one confocal point in the object space of the setup.

Embodiments relate to a polymerizable composition comprising a phosphorus-based mold releasing agent for an optical use whose preparation process is improved, and a process for preparing the phosphorus-based mold releasing agent. The phosphorus-based mold releasing agents can be prepared more easily and conveniently by using phosphorous pentoxide, which can easily react with a monoalcohol and/or water at room temperature in the absence of a catalyst or a solvent. In addition, byproducts are not generated during the reaction. Thus, when a lens is produced by using the mold release agent obtained therefrom, it is possible to prevent a defective appearance of the lens that may be caused by byproducts, thereby further enhancing the appearance properties thereof. Further, since separate steps for removing byproducts, specifically, such steps as washing and filtration, are not required, wastewater is not generated. Thus, it is not only environmentally friendly, but the production cost can also be reduced as the process is simple.

An information processing system includes a task acquisition unit configured to acquire a task to be presented to a driver, a load identification unit configured to identify a current driving load, and an output determination unit configured to determine whether the task is to be output to the driver or not. The output determination unit determines to output the task if a response expected time from output of the task to a response action by the driver is longer than a threshold value based on the driving load.

Methods and systems for monitoring use, determining risk, and pricing insurance policies for a vehicle having one or more autonomous or semi-autonomous operation features are provided. According to certain aspects, an identity of a vehicle operator may be determined and a vehicle operator profile and/or operating data regarding autonomous operation features of the vehicle may be received after the vehicle operator opts into a rewards program and agrees to share their data. Autonomous operation and vehicle operator risk levels associated with operation of the autonomous or semi-autonomous vehicle may be determined. Based upon the risk levels and/or comparison thereof, one or more autonomous operation features may be disengaged. A preparedness level of the vehicle operator to assume or reassume control of operating the vehicle is determined prior to disengagement. If satisfactory, an alert is presented to the vehicle operator prior to disengagement of the autonomous operation features.

A tire monitoring device comprising a sensor for monitoring a tire parameter and a first controller for controlling the operation of the device. A measurement apparatus is provided for generating parameter measurement data from the sensor output signal. A second controller is provided for controlling the operation of the measurement apparatus. The second controller communicates parameter data to the first controller based on the measurement data. The device is particularly suited to monitoring tire pressure and detecting tire burst events.

An output shaft receives transmission of a driving force of a motor. A valley forming member has valley portions correspondingly to shift ranges and rotates integrally with the output shaft. An engaging member is biased with a biasing member in a direction to be fitted to a valley portion and is configured to be fitted to a target valley portion, which is a valley portion corresponding to a target shift range. The motor control unit performs a control to drive the motor. The motor shaft, which is a rotary shaft of the motor, and the output shaft have a play therebetween. The motor control unit determines a motor target position to locate the engaging member at a position shifted by a predetermined amount before the center of the target valley portion in the driving direction.

A vehicle electronic key system acquires a vehicle vibration, which is a vibration generated in a vehicle, at a time of a driver's door of the vehicle being closed after a driver is presumed to get in the vehicle, and a key vibration, which is a vibration generated in an electronic key, at the time of the driver's door being closed after the driver is presumed to get in the vehicle. The system determines whether or not the vehicle vibration and the key vibration at the time of the driver's door being closed match each other, and permits an operation of a predetermined operation target device mounted in the vehicle on the condition that the vehicle vibration and the key vibration match each other.
