  • Publication number: 20140098283
    Abstract: An efficient method and system for estimating an optimal focus position for capturing an image are presented. Embodiments of the present invention initially determine an initial lens position dataset. Then, scores are calculated for each value of the initial lens position dataset producing a plurality of scores. Embodiments of the present invention then determine an optimum focus position through interpolation and extrapolation by relating the initial lens position dataset to the score dataset, in which the score dataset comprises of the plurality of scores.

  • Publication number: 20140099090
    Abstract: Embodiments of the present invention initially calculate a confidence score for the image environment surrounding the subject matter in order to determine the initial number of lens positions. Once the initial lens positions are determined, a sharpness score is calculated for each determined initial lens position. Using these sharpness scores, embodiments of the present invention generate a projection used to locate an estimated optimum focus position as well as to determine an estimated sharpness score at this lens position. Embodiments of the present invention then position the lens of the camera to calculate the actual sharpness score at the estimated optimum focus position, which is then compared to the estimated optimum sharpness score previously calculated. Based on this comparison, embodiments of the present invention dynamically determine whether it has a sufficient number of lens positions to determine the optimum focus position or if additional sample lens positions are needed.

  • Publication number: 20130196195
    Abstract: The present disclosure is directed at a cell carrier, a stack that includes multiple cell carriers, and a method for assembling the stack. The cell carrier has a rigid backing and bus bar supports that are rigidly mounted to the rigid backing The bus bar supports have sockets positioned to receive fasteners for securing bus bars to the bus bar supports. A battery cell that has electrodes in the form of pliable tabs can be secured to the cell carrier by, for example, adhering the cell body to the rigid backing The cell tabs are secured between the bus bars and the bus bar supports when bus bars are fastened to the bus bar supports, and the rigidly mounted supports help prevent relative motion between the cell body and tabs. This helps prevent the cell tabs from ripping or tearing when the battery cell is subjected to vibrations during use.

  • Publication number: 20110099792
    Abstract: A method for assembling a snap clip lug. The snap clip lug is assembled by inserting a resilient arm into a sleeve opening. The resilient arm is connected at one end to a base of a clasp member and has a locking tab at the other end. The sleeve is defined in a receptacle member with an opening at one end and a locking slot at the other end. The resilient arm is flexed in a first lateral direction during insertion into the sleeve opening. When the locking tab is engaged in the locking slot, the resilient arm flexes in a second lateral direction, causing it to be retained in the sleeve, thereby forming the snap clip lug.
