  • Patent number: 6418393
    Abstract: An inspecting device for a thermal module for cooling a CPU of a computer to decide whether the module can work properly is disclosed. The device includes a computer stored with preset data. A measuring unit has a heater generating heat with a predetermined temperature. A converter electrically connects the heater with the computer and converts an analogous signal corresponding to the temperature of the heater to a digital signal which is sent to the computer. A force generating mechanism is provided on the measuring unit which can generate a pressing force toward the heater. When the heater is contact with a heat-generating component contact part of the thermal module and the force generating mechanism is activated to press the part against the heater, the computer compares the data stored therein and the signal received from the converter to determine whether the thermal module can attain its required performance.

  • Patent number: 6397163
    Abstract: A computer-based method of determining a thermal exposure of a product disposed within a shipping container to determine whether a conditioned environment is required for shipping. A shipping route is defined from a first geographic location to a second geographic location. The thermal characteristics of the shipping container are provided, as is a historical weather database. Ambient temperatures, cloud cover and humidity from the historical weather database are retrieved which correspond to the shipping route. A system of mathematical equations are generated to correspond the retrieved ambient temperature to an ambient temperature within the shipping container and to the product temperature. The corresponding product temperature is compared to a thermal exposure profile for the product to determine if the corresponding product temperature is within the thermal exposure profile.

  • Publication number: 20020022941
    Abstract: The present invention is a temperature sensor which is based on the actual temperature coefficients of a device in the circuit, rather than a predetermined threshold voltage that varies across different devices. This temperature sensor includes a circuit which determines the temperature of a device. More particularly, CMOS circuit is provided which uses a current source to generate charge and discharge voltages applied to a capacitor. These voltages are dependent on the temperature coefficient of a resistor in the current source. The charge and discharge times are then used to determine a frequency which is dependent on the temperature coefficient of the resistor. Thus, the temperature is sensed based on the output frequency of the circuit. Additionally, the present invention includes a mechanism which allows the temperature sensor to be activated or deactivated as needed.

  • Publication number: 20010020221
    Abstract: A control unit takes in a set temperature, a vehicle-internal temperature, an ambient temperature, an engine-water temperature, an sun load and a vehicle speed from a means for setting a temperature of the air inside a vehicle and sensors (S1). The control unit determines whether a failure has occurred in the internal-air-temperature sensor and the external air temperature sensor respectively (S2, S3). If a failure is determined in any of the sensors, the control unit fetches a substitute value registered in advance in the substitute-value table (S10, S11). Then, the flow of the procedure goes on to a step S4 and an outlet temperature and as well as a difference between the vehicle-internal temperature and the set temperature are found from the signals generated by the sensors, and a driving voltage of the FAN motor and switching position of the outlet flap is computed (S5, S6).

  • Patent number: 6269321
    Abstract: A method for quantitatively predicting and consequently minimizing the amount of critical phases such as eutectic Al2Cu formed during solidification of Al—Si—Cu alloys used in a vehicle engine component comprises developing a micromodel to simulate microstructure evolution in cast Al—Si or Al—Cu alloys. The micromodel is calibrated using experimental thermal analysis cooling curves and an optimization process. Microstructure evolution and cooling curves are simulated for a casting using the calibrated micromodel. Precipitation of critical phases such as Al2Cu in the casting is predicted as a function of solidification conditions. The model allows casting process variables to be varied with predictable results so that the casting process can be controlled via the micromodel.

  • Patent number: 6183128
    Abstract: This invention relates to an apparatus and method for determining paperboard thermal conductivity. Such structures of this type, generally, determine the thermal conductivity of a planar material, such as paperboard or insulating foams. The apparatus is designed to characterize the heat flow from a heated brass cylinder, through a flat paperboard sample, and into another brass cylinder. The brass cylinders are fully insulated, except at the sample interface. During the test, which is in a transient state, the hot mass loses energy, raising the temperature of the cooler mass as the two masses approach an intermediate equilibrium temperature. Knowing that the brass masses are fully insulated, except for the heat transfer interface, and knowing the physical properties of the masses, the only unknown in the mathematical model describing the experiment is the thermal conductivity, k, of the paperboard sample, which enables its determination.

  • Patent number: 6098030
    Abstract: An integrated circuit which includes a temperature modeling circuit for reducing operational activity of the integrated circuit when its operating temperature exceeds a predefined threshold. The temperature modeling circuit includes several multiplexers each of which corresponds to a particular sub-circuit within the integrated circuit. The multiplexers select one of at least two heat generation values inputted thereto in accordance with the operating mode of the corresponding sub-circuit. A multi-input adder adds the selected heat generation values along with values representing the rate at which heat is being dissipated by the integrated circuit, the rate at which heat is being generated by background operations of the integrated circuit, and a previous temperature of the integrated circuit. The added values relate to the current operating temperature of the integrated circuit which is compared to a predefined temperature using a comparator.

  • Patent number: 6014611
    Abstract: Two cooling functions are provided: one being reduction in operation speed of a CPU, and the other being rotation of a motor fan. The two cooling functions are selectively used in accordance with a cooling mode set by a user. When a "Quiet" mode is selected by the user, a mode giving a priority to low power consumption is set to make the battery operation time as long as possible. In this case, the motor fan is not rotated and only the CPU operation speed is lowered. On the other hand, when a "Performance" mode is selected by the user, a mode giving a priority to performance is set. In this case, the CPU operation speed is not lowered, and only the motor fan is rotated. The "Performance" mode and "Quiet" mode can be freely set by the user on a setup screen.

    Abstract: A method for temperature compensation in measuring systems that are dependent on the operating temperature and whose temperature dependency is caused by temperature-sensitive components that can be operated electronically, or are linked thermally with a neighboring electronically driven component which is already required for the measuring system. In the method according to the invention, the temperature-sensitive component or a neighboring component are operated in such a way that temperature compensation can be performed without any further auxiliary means such as, for example, an additional heating device. Temperature compensation of this kind can then take place in three different ways. In the one method, the temperature coefficient determined and utilized; in a second method the temperature-sensitive components of the system are heated up to a fixed operating temperature, which is the basis for all measurements, and in a third method a temperature-independent operating point is determined.
