摘要： A locking mechanism for use in a multi-thread environment supporting self-modifying code in which modifications to the code are made at runtime. The locking mechanism having associated helper code accessed by a call from the first instruction address in the code block. The helper code calculating the binary encoding for the call instruction and using an atomic compare and exchange instruction to compare the calculated binary encoding with the actual contents of the first instruction address. Where there is a match, a self loop instruction is written to the first instruction address to lock the specified code block for subsequent threads. The helper code contains instructions to resolve the references in the specified block. The last such instruction is an atomic store operation to replace the self loop instruction at the first instruction address with the appropriate modified instruction.

摘要： A thermal management device for an enclosure, the enclosure disposed in an environment exposed to ambient air and having an interior area for housing heat generating electronic components includes a heat exchanger having an evaporator portion and a condenser portion, the evaporator portion is adapted for mounting within the enclosure interior area adjacent to the heat generating electronic components. The condenser portion is exposed to the ambient air for removal of heat from the enclosure interior area generated by the electronic components adjacent to the heat exchanger evaporator portion. The device is incorporated in a system which includes an air duct disposed within the enclosure interior area. The duct includes an air inlet port and air outlet port. The ports communicate with the ambient air to thereby create an airflow path through the air duct from the inlet port to the outlet port. The condenser portion of the heat exchanger is adapted to communicate with the air flow path within the air duct, such that heat generated by the electronic components adjacent to the heat evaporator portion of the heat exchanger within the enclosure is removed from the enclosure through the air duct to the environment.

摘要： A passive cooling system for cooling an enclosure containing electronic components. A hollowed portion of the enclosure is formed as an integral heat pipe containing a working fluid. The hollowed portion has an evaporator section located at the top and a condenser section located at the bottom. The enclosure also has hollowed side walls which serve as passage ways for the working fluid to flow through in between the evaporator and condenser sections. Gravity and the pressure of evaporation force the working fluid down to the condenser section. A wick is provided for returning the working fluid to the evaporator section by capillary action. Additionally, an ultrasonic transducer driven by the heat rejected from the condenser section may be used to help return the working fluid to the evaporator section. Finally, a check valve may be employed before the evaporator section for the working fluid to flow through.

摘要： A phase change material, including multiple phase change materials of different formulations, is placed in heat transfer association with an electronics enclosure (e.g., a sealed enclosure) deployed in an environment that causes the electronics and the phase change material to experience periods of heating and periods of cooling. During the periods of heating, the phase change material absorbs heat and changes at least partially from a first state to a second state to maintain the temperature of the electronics at a desirable level. During the periods of cooling, the phase change material reverts at least partially back to the first state for future heat absorption. The phase change material is cooled by a thermally cooler body such as the night sky. The electronics enclosure and phase change material may be placed in a second enclosure covered with a paint having a paint additive that reflects solar radiation.

摘要： In typical Java and other interpreted programming language environments, the code is stored in ROM in a semi-processed state, .class files containing byte codes. When the device is turned on, a virtual machine resolves references and links the .class file in RAM to permit desired applications to be run. In the invention, the .class files are further pre-processed to select the data which will not change or require updating. This data is packaged into memory image files containing internal data pre-linking this data. The memory image files are stored in ROM and are accessible from ROM by the virtual machine at runtime. Only elements that will be updated, such as the objects themselves, must be instantiated in RAM at runtime. This reduces the amount of RAM needed to run the application. In an environment with memory constraints, the reduction in RAM requirements permits more RAM to be made available for application use.

摘要： The illustrative embodiments provide a computer implemented method, apparatus, and computer program product for accelerating execution of a program, written in an object oriented programming language, in an emulated environment. In response to receiving a request for an accelerated communications session from a guest virtual machine in the emulated environment, a native virtual machine is initiated external to the emulated environment but within the computing device hosting the emulated environment. Thereafter, an accelerated communications link is established between the guest virtual machine and the native virtual machine. The accelerated communications link enables a transfer of managed code between the guest virtual machine and the native virtual machine. The managed code is then executed by the native virtual machine.

摘要： The stack mapper of the present invention seeks to determine the shape of the stack at a given program counter. This is accomplished by locating all start points possible for a given method, that is, at all of the entry points for the method and all of the exception entry points, and trying to find a path from the beginning of the method to the program counter in question. The mapper first tries to locate a linear path from the beginning of the method, and then iteratively processes the sequence of bytes at each branch until the destination program counter is reached. Once the path is found, a simulation is run of the stack through that path, which is used as the virtual stack for the purposes of the garbage collector.
