  • Patent number: 7628252
    Abstract: A type of drum brake for automobiles that is comprised of a brake drum, one or more brake shoes, and one or more brake cylinders. Its special characteristics are: the drum brake further comprises an ordinary gear train which comprises an annulus, one or more planetary gears and a sun gear. Here, the annulus is attached to the brake drum. The sun gear and a mounting shell of the brake shoes are attached to each other. The planetary gears are located between the annulus and the sun gear, and one or more planetary gear axles of the respective planetary gears are affixed with one or more planetary carriers. By adopting the drum brake of this invention and the ordinary gear train, when the brake is applied, the brake shoes rotate in the opposite direction relative to the moving direction of the brake drum, thereby greatly reduce the braking distance and braking time.

  • Patent number: 7565244
    Abstract: Characterizing a reservoir with electromagnetic imaging surveys includes normalizing measured voltage data by transmitter moment, sorting the normalized voltage data into common receiver profiles, densely resampling transmitter locations using common positions for the receiver profiles, coarsely resampling the data at discreet transmitter locations, defining a starting model for inversion, weighting the data by a factor, converting the normalized voltage data to ratios, calculating a conductivity image using a ratio inversion method, and verifying that an inversion has converged and the image is geologically reasonable. The image can then be displayed. The invention can be used for cross-well, surface-to-borehole, and borehole-to-surface measurements by which the effects of steel casing are reduced.

  • Publication number: 20090157320
    Abstract: To characterize an earth subterranean structure using a measurement assembly including electromagnetic (EM) receivers and one or more EM sources, measured voltage data collected by EM receivers in response to transmission by one or more EM sources is received. Based on a model, predicted EM data is computed. Inversion is iteratively performed according to a function that computes a difference between the measured voltage data and a product of a term containing the predicted EM data and a term containing distortion data that accounts at least for distortion effect by an environment of the measurement assembly. The inversion is iteratively performed to solve for parameters of the model and the distortion data.

  • Publication number: 20090150124
    Abstract: One embodiment of the invention involves a method for determining whether an electromagnetic survey will be able to distinguish between different subsurface conditions in an area that includes developing a three-dimensional electromagnetic property model of the area, and simulating an electromagnetic response of a field electromagnetic data acquisition system using the three-dimensional electromagnetic property model to determine if expected differences in an electromagnetic response of a electromagnetic data acquisition system are within detectability limits of the system. Another embodiment involves a model-based method of inverting electromagnetic data associated with a subsurface area that includes developing a three-dimensional electromagnetic property model of the area, and restricting changes that may be made to the model during the electromagnetic data inversion process. Other related embodiments of the inventive method are also described and claimed.

  • Publication number: 20080314168
    Abstract: A testing system for a power supply (40) includes a testing chamber (10), a control switch, an electrical load (50), an AC source (60), and a PLC (30). The power supply has a voltage choice switch. The testing chamber receives the power supply therein. The testing chamber provides a first or a second ambient temperature and supplies a testing environment for the power supply. The control switch switches the power supply to operate between a standby state and an operational state. The electrical load is connected to the power supply. The AC source is connected to the power supply. The AC source outputs the first voltage or the second voltage to the power supply. The PLC controls switching states of the voltage choice switch and the control switch in a manner such that the power supply selectively operates in one of combined switching states of the voltage choice switch and the control switch.
