  • Patent number: 6778393
    Abstract: A cooling device having a common cooling distribution unit with multiple compliant cooling elements. Mechanisms are built in to ensure the cooling elements are in good thermal contact with heat generating semiconductor chips of different heights and sizes on a common carrier. The cooling distribution unit has protection structures to prevent the leakage of coolant from the unit. Further reduction of the risk of accidental coolant leakage is provided with the onboard storage of coolant absorbent materials in the coolant distribution unit. The cooling elements have serpentine coolant channels to enhanced the cooling capacity. The compliance of the cooling elements can also be achieved by using concentric tubing to connect the coolant distribution unit to cooling heads on the cooling elements.

  • Patent number: 6778160
    Abstract: A liquid crystal display comprises an input for inputting a video signal from a host and a storage medium for storing the previous brightness level of the video signal input through the input. A determinator is provided for determining an output brightness level based on the previous brightness level stored in the storage medium and the next brightness level of the next video signal input to the input, so as to make the time integration quantity of a brightness change substantially equal to an ideal quantity of light in a stationary state with respect to the next brightness level. Further included are drivers for driving an image displaying liquid crystal cell based on the output brightness level determined by the determinator.

  • Patent number: 6772171
    Abstract: A method for creating an object in a non-persistent memory is proposed. From an instruction code sequence, a first instruction code is read out which effects the execution of a first function which effects the choice of a non-persistent memory as the location for the next object to be created. This object creation is effected by the execution of a second function which is effected by reading out a second instruction code. Furthermore it is proposed to store a pointer to a transient object in the stack memory and to provide a mechanism for writing this pointer to and reading it from a persistent memory.

  • Patent number: 6604140
    Abstract: A method, apparatus and computer product that enables one or more computing devices to discover and use services over a network, which may be ad-hoc when the computing device is mobile. Service discovery is based on periodic multicasting of exported service descriptions to nearby devices over the (ad-hoc) network. Middleware enables a device to discover, advertise and use services. This enables software clients on the same device to share a service implementation (in the case of a local service) or to share an implementation proxy (in the case of a remote service). Each device being aware of the services (and service locations) that are currently available generally reduces the response time associated with accessing available services. While service descriptors are multicast and discovered, the service software is only downloaded on the device when the service is used. This enables economical resource management that is particularly useful for mobile devices.
