  • Patent number: 9018878
    Abstract: A machine propelled by an electric motor and subject to a deration scheme is described wherein deration is specified by a combination of a temperature signal indicating a degree to which a machine component is overheating. The machine includes an electronic controller that receives a temperature signal indicative of a current temperature status of the electric motor. The electronic controller receives a motor speed signal indicative of a current speed status of the electric motor. The electronic controller calculates, in accordance with a derating scheme, a deration value for the electric motor, the deration value being determined by applying a set of current operating state parameter values to the derating scheme. The set of current operating state parameters include: a motor speed parameter value; and a temperature parameter value.

  • Publication number: 20140226477
    Abstract: Embodiments of the present invention disclose a method, an apparatus, and a system for improving user experience of a small flow user. A base station controller (BSC) periodically collects statistics on an average data transmission rate of a terminal. The BSC compares the average data transmission rate with a set threshold and determines whether the average data transmission rate is smaller than the set threshold. The BSC sends a first priority adjustment command to a base transceiver station BTS if the average data transmission rate is smaller than the set threshold. The first priority adjustment command carries information of adjusting a scheduling priority of the terminal to a high priority, so that the BTS can adjust the scheduling priority of the terminal to the high priority.

  • Publication number: 20140141876
    Abstract: The current invention discloses devices and methods that may be used for detection and verification of interactions, such as collisions, between objects in application programs, such as online games. After receiving interaction information from a first terminal, a server may send the interaction information to another terminal for verification based on the first terminal's credit rating. When the credit rating is high, the server may broadcast the interaction information before the verification process, which may be conducted randomly. On the other hand, when the credit rating is low, the server may wait for the verification results from the other terminal and only broadcast the interaction information when the information is confirmed. Such an approach optimizes the interaction verification process, reduces security risk, and saves computing resources.

  • Publication number: 20140053866
    Abstract: A cleaning method for a UV chamber involves providing a first cleaning gas, a second cleaning gas, and a purge gas to one or more openings in the chamber. The first cleaning gas may be an oxygen containing gas, such as ozone, to remove carbon residues. The second cleaning gas may be a remote plasma of NF3 and O2 to remove silicon residues. The UV chamber may have two UV transparent showerheads, which together with a UV window in the chamber lid, define a gas volume proximate the UV window and a distribution volume below the gas volume. A purge gas may be flowed through the gas volume while one or more of the cleaning gases is flowed into the distribution volume to prevent the cleaning gases from impinging on the UV transparent window.

  • Patent number: 8635000
    Abstract: A brake monitoring system for a machine has at least one traction motor coupled to drive wheels of the machine. An operator input device receives a requested retarding torque from an operator of the machine and sends a signal to a controller that is configured to compare the required retarding torque to a maximum retarding torque available at a particular speed of the traction motor. The controller selectively generates a warning signal based on a comparison of the required retarding torque to a maximum retarding torque available.

  • Patent number: 8492170
    Abstract: Methods for the repair of damaged low k films are provided. Damage to the low k films occurs during processing of the film such as during etching, ashing, and planarization. The processing of the low k film causes water to store in the pores of the film and further causes hydrophilic compounds to form in the low k film structure. Repair processes incorporating ultraviolet (UV) radiation and silylation compounds remove the water from the pores and further remove the hydrophilic compounds from the low k film structure.
