Abstract: A threat detection system and method for detecting panic detection in a crowd of people. The threat detection system using software algorithms detect people's movement from video camera scene and video feeds. The system analyses the recent history of the scene to describe features that would be considered common/normal in the scene when enough people are present. The system then uses that baseline information to continually analyze frames with the requisite number of people in a frame and update the baseline features. If the features of the scene change dramatically based on the perceived movement of the people in the scene and meet or exceed the threshold features for movement in enough consecutive frames, then the systems determines that there is panic in the scene.

Abstract: A bearing cap for attachment to a cylinder block, the bearing cap comprising: receiving means for receiving a crankshaft bearing; contact means for contacting the cylinder block, and at least two projection means extending from the contact means for positioning the bearing cap on the cylinder block for attachment, wherein each of the projection means comprises an externally facing contact surface each of which is dimensioned to simultaneously contact a different receptacle of the cylinder block when positioning the bearing cap on the cylinder block for attachment, and an internally facing non-contact surface each of which is dimensioned to simultaneously not contact the respective receptacle of the cylinder block when positioning the bearing cap on the cylinder block for attachment.
