Patent number: 8577776Abstract: A data driven and forward looking risk and reward appetite methodology for consumer and small business is described. The methodology includes account level historical data collection for customers associated with accounts as part of a portfolio. The account level historical data is segmented into groups of customers with similar revenues and loss characteristics. Segmented data is decomposed into seasoning, vintage, and cycle effects. Statistical clusters are formed based upon the data and effects. A simulation is applied to the statistical clusters and prediction data is generated. A simulation strategy to forecast and simulate revenue and loss volatility is developed. Efficient frontier curves of risk (e.g., return volatility) and reward (e.g., expected return) are created for the current portfolio under various economic scenarios.Type: GrantFiled: September 14, 2012Date of Patent: November 5, 2013Assignee: Bank of America CorporationInventors: Agus Sudjianto, Michael Chorba, Daniel Hudson, Sandi Setiawan, Jocelyn Sikora, Harsh Singhal, Kiran Vuppu, Kaloyan Mihaylov, Jie Chen, Timothy J.

Patent number: 8534988Abstract: A fan assembly includes a mounting bracket, a fan, and a baffle. The mounting bracket includes two side plates bounding an outlet, and each side plate defines a through hole. An inner side bounding the through hole defines an arc-shaped cutout, communicating with the through hole. The baffle includes two pins rotatably received in the through holes of the side plates. A protrusion protrudes out from each pin, and is engaged in the corresponding cutout. When the fan operates, the baffle is pushed to rotate to open the outlet, to allow air from the fan to flow out through the outlet. When the fan ceases operation, the baffle rotates back under force of gravity to a position to cover the outlet, where the protrusion resists against one end of the cutout such that further rotation is prevented, to prevent air intake into the mounting bracket through the outlet.Type: GrantFiled: December 11, 2010Date of Patent: September 17, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Guang-Yi Zhang, Zhe Zhang

Patent number: 8326723Abstract: A data driven and forward looking risk and reward appetite methodology for consumer and small business is described. The methodology includes customer segmentation to create pools of homogeneous assets in terms of revenue and loss characteristics, forward looking simulation to forecast expected values and volatilities of revenue and loss, and risk and reward optimization of the portfolio. One methodology used for modeling revenue and loss is a generalized additive effect decomposition model to fit historical data. Based on the model, a segmentation procedure is performed, which allows for creation of groups of customers with similar revenue and loss characteristics. An estimation procedure for the model is developed and a simulation strategy to forecast and simulate revenue and loss volatility is developed. Efficient frontier curves of risk (e.g., return volatility) and reward (e.g., expected return) are created for the current portfolio under various economic scenarios.Type: GrantFiled: August 25, 2009Date of Patent: December 4, 2012Assignee: Bank of America CorporationInventors: Agus Sudjianto, Michael Chorba, Daniel Hudson, Sandi Setiawan, Jocelyn Sikora, Harsh Singhal, Kiran Vuppu, Kaloyan Mihaylov, Jie Chen, Timothy J.
