摘要:
A variety of structures and methods used to adjust the shape, radius and/or height of a microlens for a pixel array. The structures affect volume and surface force parameters during microlens formation. Exemplary microlens structures include a microlens frame, base, material, protrusions or a combination thereof to affect the shape, height and/or radius of the microlens. The frame, base and/or protrusions alter the microlens flow resulting from the heating of the microlens during fabrication such that a height or radius of the microlens can be controlled. The radius can be adjusted by the height differences between the microlens and frame. The bigger the difference, the smaller the radius will be.

A signal detector includes a transform unit and a post processing test unit. The transform unit is adapted to a transform unit adapted to receive at least first and second frames of input samples, determine a first plurality of energy values for the first frame based on a first set of transform coefficients, and determine a second plurality of energy values for the second frame based on a second set of transform coefficients. The post processing test unit is adapted to identify at least one target frequency based on the first plurality of energy values. The second set of transform coefficients is based on the target frequency, and the post processing unit is adapted to determine the presence of a first signal in the input samples based on the second plurality of energy values. A method for detecting a signal is provided. A first frame of input samples is received. A first set of transform coefficients is determined based on a first plurality of frequencies. A first plurality of energy values is determined based on the first set of transform coefficients. A target frequency is determined from the first plurality of frequencies based on the first plurality of energy values. A second set of transform coefficients is determined based on the target frequency. A second frame of input samples is received. A second plurality of energy values is determined based on the second set of transform coefficients. The presence of the signal in the input samples is determined based on the second plurality of energy values.

A method for the control of a bi-directional overrunning clutch assembly (10) disposed within a vehicle transmission, including the steps of initiating a drive function control routine (112) within an electronic control unit and sensing the commanded gear ratio within the transmission. The method steps further include determining whether a first gear function (132) should be initiated based on the commanded gear ratio and determining whether a second gear function (150) should be initiated based on the commanded gear ratio. The method also includes sensing whether the reverse engagement members (24B) and the forward engagement members (24A) of the bi-directional clutch (10) are engaged when neither the first gear function (132) nor the second gear function (150) are initiated.
摘要:
A rate-distortion optimized embedding (RDE) coder optimizes rate-distortion performance by coding information bits in the order of their R-D slope. RDE allocates the available coding bits first to the information bit with the steepest R-D slope, which indicates the largest distortion decrease per coding bit. The resultant RDE bitstream can be truncated at any point and still maintain an optimal R-D performance. To avoid the overhead of coding order transmission, an expected R-D slope is calculated by both the encoder and the decoder from previous RDE coded bits. A probability estimation table from a QM arithmetic coder allows the R-D slope to be derived using a lookup table operation. The rate-distortion optimised embedding (RDE) coder significantly improves the coding efficiency over a wide range of bit rates.

A signal detector includes a transform unit, a gain control unit, and an energy level threshold unit. The transform unit is adapted to receive a plurality of input samples and calculate a first plurality of delay values based on the input samples. Each delay value is based on at least one previous delay value and a current input sample. The transform unit is adapted to calculate a first energy value based on at least a subset of the first plurality of delay values. The gain control unit is adapted to determine if a selected delay value of the first plurality of delay values exceeds a predetermined threshold and scale the selected delay value, the at least one previous delay value used to calculate the selected delay value, and subsequent input samples received after the current input sample by a first amount in response to the selected delay value exceeding the predetermined threshold. The energy level threshold unit is adapted to determine the presence of a first signal in the input samples based on the first energy level.

An adaptive image coding method and system are disclosed. The system accepts an input image, divides it into image segments, and assigns each segment to a wavelet transform filter from a bank of such filters for transformation. The bank preferably comprises filters adapted for different types of image content, e.g., sharp edges, slowly-varying contours, etc. Filters are preferably assigned so as to produce minimal distortion for their assigned image segments at a given target bit rate, each filter produces transform coefficients for its segment using scale and subband settings common to the entire image. The valid coefficients for each segment are then combined in a composite wavelet coefficient image, which resembles a single wavelet transform of an entire image—although different filters are used to create different portions of the coefficient image. The composite image allows joint, rate-distortion optimized coding for a segmented image. Joint coding allocates bits between the transforms of the image segments optimally, and produces an easily scaleable bitstream.

An arbitrary shape wavelet transform with phase alignment (ASWP) is used to transform an arbitrary shaped object in an image. The phase of an odd tap wavelet filter is aligned so that a low pass filter is always centered at an even index, and a high pass filter is always centered at an odd index. The phase of an even tap wavelet filter is aligned so that the low pass filter and the high pass filter are both centered at index 2i+0.5, i.e., a half index past the even index. The objects for odd tap wavelet filters are each separately symmetrically extended by mirroring the objects from the opposite ends but not mirroring the end pixels. The objects for the even tap filter is symmetrically extended by mirroring the pixels from the opposite ends of the objects including mirroring the end pixels. The phase adjusted-symmetrically extended objects are then transformed.

A border menu can be presented on four sides of an outer border of a graphical user interface. The border menu can be presented at the top of a stack of a graphical user interface. The border menu can include a set of user-selectable options, each selectable via a pointing device, each of the user-selectable options being associated with at least one of an icon or text button. At least one of the user-selectable options can be presented along each of the four sides of the outer border of the border menu. Selection of each of the user-selectable options can result in triggering an event, which results in firing of a programmatic action to run executable code for a corresponding one of the user-selectable options. At least a portion of the user-selectable options can include application-specific options for an application running on the computing device.
