    • Method and apparatus for optically testing (e.g., using a laser beam) an operating integrated circuit (device under test—DUT) that actively control the operating temperature of the DUT. This is chiefly useful with flip-chip packaged ICs. The temperature of the DUT varies with its operating power consumption, and this fluctuation in temperature adversely affects the results obtained during optical probing or other optical testing. Furthermore, the DUT may be damaged if its temperature exceeds design limits. The temperature of the DUT is controlled by thermally contacting the exposed backside surface of the DUT die to a diamond film heat conductor, an associated heat sink structure, and at least one thermoelectric device. The thermoelectric device is controlled by a temperature sensor proximal to the DUT. By controlling the amount and direction of the electrical current supplied to the thermoelectric device in response to the sensed temperature, the temperature of the DUT is maintained.
    • 用于光学测试(例如,使用激光束)用于主动控制DUT的工作温度的操作集成电路(被测器件)的方法和装置。 这主要用于倒装芯片封装IC。 DUT的温度随其工作功耗而变化,这种温度波动对光探测或其他光学测试中获得的结果产生不利影响。 此外,如果DUT的温度超过设计限制,则DUT可能会被损坏。 DUT的温度通过将DUT的裸露背面与金刚石膜热导体,相关联的散热器结构和至少一个热电装置热接触来控制。 热电装置由靠近DUT的温度传感器控制。 通过控制响应于感测温度供应到热电装置的电流的量和方向,保持DUT的温度。

    • A system for the remote acquisition of data and for the remote control of electricity meters comprises a central server AMM in bi-directional communication with a plurality of concentrators. To each concentrator, a set of electricity meters is connected, such that bidirectional communication between each meter and its associated concentrator is possible. The intelligence of the system is distributed between the central server, the concentrators and the electricity meters. To this end, each meter comprises at least a first processor, a first data memory and a first program memory for bi-directional communication with the associated concentrator. The first data memory serves to at least temporarily store and/or transmit the data which have already undergone a first processing by the first processor. Each of the concentrators comprises a second processor, a second program memory and a second data memory as well as means for a bi-directional communication with a central server. The second data memory serves to temporarily store and/or transmit the data processed by the second processor.
