  • Patent number: 6738977
    Abstract: A system includes first and second virtual machines (VM) representing a master and a client respectively. A class file is loading by the first virtual machine into shared memory. The class file includes sharable and non-sharable data, and also references sharable and non-sharable data (including code). When it is desired to load the same class into the second virtual machine, the class is first located within said shared memory. A mirror copy of the class is then formed within private memory in the second virtual machine. Finally the non-sharable data of the class is completed in the private memory. Thereafter, an application in the second virtual machine can utilise the class on the basis of the sharable data in the shared memory of the first virtual machine, and the non-sharable data from the private memory of the second virtual machine.

  • Patent number: 6730416
    Abstract: The invention modifies and converts neutral dye molecules (D) to ionic salts (D-A+ X− or DA− X+), and employs them as emitting or charge transport layers in organic light emitting diodes (OLED's). This is achieved by attaching ionizable substituents (A) on the dye molecule during initial synthesis, and then reacting it with an appropriate agent that contains charge balancing ions (X). These ionic compounds can be deposited as amorphous films using conventional evaporation techniques. In addition, they are thermally stable to crystallization. OLED devices incorporating such dye salts for emitting layers exhibit superior efficiencies and durability compared with devices using neutral dye molecules.

  • Patent number: 6724069
    Abstract: A spin-on cap useful as a post-CMP cap for Cu interconnect structures is provided. The inventive spin-on cap includes a low-k dielectric (on the order of 3.5 or less) and at least one additive. The at least one additive employed in the present invention is capable of binding Cu ions, and is soluble in the spun-on low-k dielectric. The spin-on cap of the present invention may further include a spun-on low-k (on the order of 3.5 or less) reactive-ion etch (RIE) stop layer. Spin-on caps containing a bilayer of low-dielectric plus at least additive and low-k RIE stop layer are preferred. It is noted that the inventive spin-on cap of the present invention does not significantly increase the effective dielectric constant of the interconnect structure and does not add additional cost to the fabrication of the interconnect structure since a single deposition tool, i.e., spin coating tool, is employed. Moreover, because of the presence of the additive in the spin-on cap, Cu migration is substantially minimized.

  • Patent number: 6711699
    Abstract: This invention involves tracking and backing all the information that a user generates on its computer devices (including embedded devices) in real time. The local user server records all user actions and gestures (via various means that include TV cameras). All of this information (user actions and saved files in a computer) is then sent to a remote server via the Internet. This remote server has a virtual map of all the embedded devices on a computer that the person uses. The remote server immediately starts to interpret the user's actions (including user gestures). In one implementation, the invention stores user actions that are related to data generation (e.g. actions that called some links where data is stored, or executed some programs that generated data). In another variant, the remote server generates and downloads the same files that are downloaded on the local user computer devices.

  • Patent number: 6694346
    Abstract: In a virtual machine environment, the invention enables creation of a long running, reusable, virtual machine are disclosed. The environment includes a shared heap where requisite runtime code to bring the virtual machine into a ‘ready’ mode are loaded, linked, verified, initialized and compiled. Subsequent virtual machines are started and jointly use the shared heap. Applications create their objects in ‘private heaps’ that are exclusively reserved for the respective applications. At the end of execution of an application, each private heap is reinitialized. Static initializers are run in a persistent area of each private heap. This persistent area is reset to its initial values in between execution of applications. This obviates the need to terminate the virtual machine.
