Abstract: Memory performance in a computer system that implements large page mapping is improved even when memory is scarce by identifying page sharing opportunities within the large pages at the granularity of small pages and breaking up the large pages so that small pages within the large page can be freed up through page sharing. In addition, the number of small page sharing opportunities within the large pages can be used to estimate the total amount of memory that could be reclaimed through page sharing.

Abstract: A multi-factor user authentication framework using asymmetric key includes a host device, a user agent, a gesture system, and an authentication system. The multiple factors include a user credential as well as a user gesture that indicates that the user is present. The user interacts with the user agent via the host device in order to obtain access to something for which user authentication is needed. The authentication system maintains the user credentials, which are provided to authenticate the user in response to the authentication system determining that the user is present (which can be determined in different manners, such as using a personal identification number (PIN), biometric information regarding the user, geographic location of the gesture system, etc.). The user agent, gesture system, and authentication system can be implemented on the same device (e.g., the host device), or alternatively implemented across one or more different devices.

Abstract: A cleat includes two cams (36) comprising mutually opposed convex surfaces rotatable about parallel axes which extend vertically in a rope-trapping position of the cleat, to bring the arcuate surfaces together and apart. The cams (36) are urged towards each other to trap a rope (66) therebetween. Each cam is also mounted to a horizontal cylinder (2) for rotation about an axis of the cylinder, in order to allow the rope (66) to rotate the arcuate surfaces by pulling in a line above this horizontal axis and to free the rope.
