Abstract: Systems and methods for managing keys in a computer memory are described. In some embodiments, location addresses are determined for two key elements. A periodic time interval that is based on a time duration for performing a transaction involving a distance between the key elements is determined. One key element may be stored at a location address and then relocated to another location address after the periodic time interval has passed. In some embodiments, areas the computer memory may remain static during relocation of the key element.

Abstract: Methods, systems, and media for improving computer security and performance of security are disclosed. In one example, a computer security system comprises a key management monitor, and two key elements comprising a first key element and a second key element. The first key element is stored at a first location address within a computer memory and the second key element is stored at a second location address. The key management monitor is configured to determine or receive a time duration for performing a data dump of contents of the computer memory. In one example, the key management monitor is further configured to control a location of the first key element within the computer memory, wherein the location address of the first key element is changed within a time period that is less than the time duration for performing the data dump of contents of the computer memory.

Abstract: Technologies are shown for authenticating service requests on a communication link established using a digital certificate owned by an entity, where permissions data is associated with the digital certificate. A service request is received from the entity through the communication link. Responsive to the service request, the permissions data associated with the digital certificate is obtained and the service request checked against the permissions data associated with the digital certificate. If the service request is permitted based on the permissions data, the service request is processed. If the service request is not permitted based on the permissions data, the service request is rejected. The permissions data can be stored on a blockchain with a blockchain address in the certificate, in a certificate authority for the certificate, or locally on a server receiving the service request.

Abstract: To protect sensitive data in program code, a method includes providing a programming interface with a capability of allocating a protected region of memory which can only be accessed by authorized code. Sensitive data present in program code is stored in the protected region of memory. The method includes marking parts of code in a program as authorized or not authorized to access the sensitive data, and determining if that part of a program which is executing is authorized to access protected data by reference to the marking.

Abstract: An improved patella resection guide and a method for applying the patella resection guide during the performance of knee arthroplasty. The patella resection guide includes a plurality of gripping handles having a corresponding plurality of pivotally interconnected crossover members at distal ends of said gripping handles, an opening in each pivotally interconnecting crossover member wherein one crossover member is position inside another crossover member, a stem having a proximal end connected to each gripping handle and each pivotally interconnected crossover member wherein the members are intertwined at a crossing point and are adjoined by fastening means to said stem, and further having a distal end comprised of a female receptor, a clamp having a top flange and side flange, and adjustable locking means for fixing a distance between the teeth of the top flange.

Abstract: Systems and methods for controlling aircraft flaps and spoilers are disclosed. Systems in accordance with some embodiments include a wing having a trailing edge, and a flap positioned at least partially aft of the wing trailing edge and being deployable relative to the wing between a first flap position and a second flap position by operation of a first actuator. A spoiler can be positioned at least proximate to the trailing edge and can be movable among at least three positions, including a first spoiler position in which the spoiler forms a generally continuous contour with an upper surface of the wing, a second spoiler position deflected downwardly from the first, and a third spoiler position deflected upwardly from the first. A second actuator can be operatively coupled to the spoiler to move the spoiler among the first, second and third spoiler positions in a manner that is mechanically independent of the motion of the flap.
