Lax: Driver Interfaces for Approximate Sensor Device Access

Phillip Stanley-Marbell, Martin Rinard
2015 USENIX Workshop on Hot Topics in Operating Systems  
We present Lax, a device driver abstraction for interacting with sensors that enables power savings in exchange for occasionally returning erroneous sensor data.  ...  Because devices are accessed through interfaces provided by system software, exploiting the tolerable error for improvements in energy efficiency requires appropriate system software and hardware support  ...  The Lax Device Interface System software interfaces for approximate device access should enable the specification of three types of tolerance to deviations from correct behavior: • Latency tolerances.  ...

On the security of digital tachographs [chapter]

Ross Anderson
1998 Lecture Notes in Computer Science  
Executive Summary Tachographs are used in most heavy vehicles in Europe to control drivers' hours, and for secondary purposes ranging from accident investigation to the detection of fraud.  ...  In countries with lax enforcement, the prospective gains should be higher and the potential losses lower.  ...  With approximately 7 million drivers in Europe covered by the regulations, and with replacement cards costing perhaps 10 ECU, annual replacement could cost about 70 MECU per annum, plus perhaps an annual  ...
