Abstract: Provided herein are various embodiments of an improved device for accurate measurement along a desired axis that is tolerant to off axis movement and other environmental factors. The measurement relies on a conversion from linear displacement of a tensile element in a pulley system which is monitored by a low power rotational encoder. The orientation and mechanical architecture of the device is set to reduce the impact of off-axis movement or forces on the measurement of interest. A computing unit determines the distance measurement by determining the state of rotation in the system in the context of the system's specific design, without the need to constantly monitor the sensor.

Abstract: A system performs static program analysis with artifact reuse. The system identifies artifacts associated with the software program being analyzed. The system processes the identified artifacts for performing static program analysis and transmits either the artifacts or identifiers for the artifacts to a second processing device for performing program analysis. The second processing device receives the artifacts and uses the received identifiers to retrieve the artifacts from a networked storage system. The second device also retrieves stored summaries of previous program analysis from the networked storage system. The program analysis uses the retrieved artifacts to generate work units for static program analysis. The analysis is performed only for those work units that are determined to remain unchanged from previous static program analysis cycles.
