Abstract: A locomotive speed determination system and method receive image data of a field of view of a camera operably disposed onboard a locomotive. A speed and/or heading of the locomotive are determined as the vehicle is moving based at least in part on one or more differences in the image data.

Abstract: Facilities are provided to secure guest runtime environments (GREs). Security policy specifications may be associated with GREs. A GRE's security policy may be specific to the GRE and may also include security policy inherited from higher levels such as a host operating environment. The security policy of a GRE specifies restrictions and/or permissions for activities that may be performed within the scope of execution of the GRE. A GRE's security policy may limit what the GRE's guest software may do within the GRE. Restrictions/permissions may be applied to objects such as files, configuration data, and the like. Security specifications may be applied to execution initiated within a GRE. A GRE's security specification may restrict/permit executable objects from loading and executing within the GRE. The executability or accessibility of objects may be conditioned on factors such as the health/integrity of the GRE, the host system, requested files, and others.

The body has an impact-influencing structure in the form of a channel positioned on at least one surface of the body. A majority of a force generated by impact with a ball is absorbed by the impact-influencing structure, and a majority of a response force generated by the head upon impact with the ball is generated by the impact-influencing structure. The face may have increased stiffness as compared to existing faces, and may include a stiffening structure to create the increased stiffness, such as a porous or cellular stiffening structure.
