Abstract: Systems and methods for mitigating drowsy and/or sleepy driving may include utilizing vehicle-related and wellness-related telematics to detect and/or predict drowsy and/or sleepy driving states of a driver of a vehicle and take mitigating actions to thereby increase the safety of the driver and other people and/or vehicles in the vicinity of the driver's vehicle. Vehicle-related telematics data and wellness-related telematics data (which may include sleep data) may be collected via sensors that disposed on-board the vehicle, in the vehicle's environment, and at a personal health/fitness tracker of the driver. The collected data may be collectively interpreted to detect, predict, and/or otherwise discover information relating to a drowsy and/or sleepy state of the driver, and one or more mitigating actions may be automatically performed based on the discovered information to thereby mitigate undesirable effects of drowsy/sleepy driving and increase driving safety.

More specifically, the plurality of grains are reoriented in a manner that is most beneficial to resist combustion and inertial forces that are enacted upon a machined piston during operation.

Abstract: A lawn mowing apparatus may include sensors that are fastened to both its mower deck and its chassis. The sensors may sense a position of the mower deck in relation to the chassis. The sensed position of the mower deck may be presented to the operator via a dashboard display of the lawn tractor or transmitted via a wireless signal to another device. Based on such sensed position, an operator of the lawn tractor may manually adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable operating range. In some embodiments, servomotors may used to adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable range.

Abstract: Systems and methods are described for a storage processing service that processes multiple storage commands. The storage processing service uses tags from test storage commands to determine whether a test storage service is to be instantiated that reflects a corresponding production service. Test storage commands with the same tag are tested on that test service. Additionally, the storage processing service determines a strategy for testing processes on production services when the storage system is overloaded. In one embodiment, the test service manager can determine to stop testing processes for a period of time, and issue a shed command that queues or sheds test storage commands. Advantageously, a shed command, while active at a storage processing service, may alleviate the overload on production services. The test service manager can continue to monitor the storage system to determine whether the overload continues to exist.

The controller may further obtain a depth measurement based on the first signal, the second signal, and the third signal and generate, based on the obtained depth measurement, one or more control signals that control operation of the power tool.
