Abstract: Disclosed are various embodiments to determine network transit time for a packet. A request packet for determining a network transit time is received. A reply packet is transmitted to the requester in response to the request packet. A reply packet is transmitted to the requester. The reply packet includes information about a packet processing time. This packet processing time includes a time between the receiving of the request packet and the transmitting of the reply packet.

Abstract: This disclosure is directed at least in part to sensing movement of an electronic display and canceling perceived movement of content on the electronic display in response to the sensing. A display manager may reassign “physical pixels” to “image pixels” (or virtual pixels) such that the image appears to be stationary while the physical pixels are moving due to movement of the electronic display. For example, if the physical pixels are moving upward, the image pixels may be reassigned downward in an equal and opposite manner. The user's persistence of vision may then be reinforced by reassignment of the pixels by the display manager. For example, text displayed on the electronic display may be more readable and images more easily viewed by a user.

Abstract: An access-check system for a network server comprises an access-cache for storing access-permissions generated by the server in response to resource access requests. The system retrieves the appropriate access-permission from the access-cache in response to receipt of a request necessitating the same access-permission as already generated for an earlier processed request. A user-token cache is also employed to assign a unique user-token, to be used in the access-cache, to each user logged on to the server. Changes made to the user-token cache are reflected in the access-cache by removing from the access-cache those entries containing the changed user-token. Changes made to an access control list are reflected in the access-cache by removing from the access-cache those entries containing the server resource with which the changed access control list is associated.
