Abstract: In a general aspect, a computer implemented method can include identifying, in a program code stored in computer memory, a location of a dynamic repair target code section for an assignment to a program variable, a value of which is known only at runtime. The method can also include modifying the program code at the identified location of the dynamic repair target code section to assign an immediate value different from a correct runtime value to the program variable. The method can further include inserting, into the program code in the computer memory, a dynamic repair probe code section that is executed before the dynamic repair target code and, at runtime, modifies the immediate value in the code to contain the correct runtime value when an attack has not occurred.

Abstract: Pets require regular and controlled amounts of food and water for their best health. A single entry feeding zone ensures that only one pet can feed at a time. The single entry feeding zone contains a food bowl into which food may be dispensed. A sensor determines which pet is currently present and denies access to food if no authorized pet is present. A detection mechanism determines the amount of food each identified pet has consumed in order to manage pet diet and denies access to food if the pet has consumed the allotted amount of food. Network functionality provides remote data tracking, correlates pet feeding behavior across multiple feeders if present, and allows a pet owner to remotely adjust parameters of the feeder or view the pet through a camera.

Abstract: The present invention provides methods and compositions for detecting Mycoplasma exposure in a subject.

Abstract: Program code is modified to execute correctly only when code and data memory accesses/fetches are synchronised, i.e. data and code accesses/fetches are routed to identical physical addresses in computer memory. This indirectly defeats the MMU attack, in which code and data memory accesses/fetches to the same logical address are routed to different physical addresses. The program code is modified such that one or more sections of the code (“repair targets”) are deliberately broken so that the program code will not execute correctly, the repair targets being replaced at run time with correct code before the repair targets are executed.

Abstract: A vapor compression cooling system includes a centrifugal compressor(s) for compressing a primary fluid in a cycle including at least two compressions, and a control module for controlling the centrifugal compressor dependent upon at least a condition of a secondary fluid. The module controls a power of the centrifugal compressor by adjusting a speed of the motor driving the compressor and/or an opening of guide vanes associated with at least one impeller. The module may also control a pressure drop of a primary fluid moving through at least one expansion device. The at least two compressions may be made in parallel or in series. A related method includes compressing a primary fluid in a first and a second compression cycle and adjusting a parameter of the compressor dependent upon a calculated desired power of the compressor.

Abstract: Methods, systems, and portable devices capable of adaptive synthetic positioning while in a dead zone are described. In one method, when a portable device having a Global Navigational Satellite System (GNSS) receiver and a dead zone database enters a dead zone, it determines whether the dead zone database has a record for the dead zone. If it does, it retrieves parameters corresponding to the dead zone from the database and calculates synthetic position solutions using the retrieved parameters while in the dead zone. The portable device may also use the synthetic position solutions to help calculate position solutions when exiting the dead zone. If a dead zone database record does not exist, the portable device determines parameters for calculating synthetic position solutions in the dead zone and a new dead zone database record indicating a set of parameters based on the determined set of parameters is created.

Abstract: A vehicle heating and cooling system includes a compressor(s) for compressing a fluid in a cycle including at least two compressions, and a control module for controlling the compressor dependent upon an ambient condition. The module controls a power of the compressor by adjusting a motor speed driving the compressor and/or a pressure drop of the fluid moving through expansion devices.
