A data vault system allows for centralized storage of personal data about a consumer in a transparent multi-tiered structure including a global data store and multiple vendor or category cards. Data in the category cards describing a subset of the globally stored data to be shared with individual vendors and provide fine resolution sharing control. The data in each structure is synchronized so that vendor or category cards may be auto populated.

A system and a method for distance measurement utilizes a radio system. The distance is measured by determining the time it takes a pulse train to travel from a first radio transceiver to a second radio transceiver and then from the second radio transceiver back to the first radio transceiver. The actual measurement is a two step process. In the first step, the distance is measured in coarse resolution, and in the second step, the distance is measured in fine resolution. A first pulse train is transmitted using a transmit time base from the first radio transceiver. The first pulse train is received at a second radio transceiver. The second radio transceiver synchronizes its time base with the first pulse train before transmitting a second pulse train back to the first radio transceiver, which then synchronizes a receive time base with the second pulse train. The time delay between the transmit time base and the receive time base can then be determined. The time delay indicates the total time of flight of the first and second pulse trains. The time delay comprises coarse and fine distance attributes. The coarse distance between the first and second radio transceivers is determined. The coarse distance represents the distance between the first and second radio transceivers in coarse resolution. An in phase (I) signal and a quadrature (Q) signal are produced from the time delay to determine the fine distance attribute. The fine distance indicates the distance between the first and second transceivers in fine resolution. The distance between the first and second radio transceivers is then determined from the coarse distance and the fine distance attributes.

A method and device for accessing a broad data field having a fine resolution. The user selects a scale which can be varied. The scale controls a range within the data field. By moving the range to encompass different portions of the data field, the user can scan that portion of the data field. The present invention allows the user to simultaneously select the scale while moving the range over different portions of the data field. Thus, the user can "zoom in" and "zoom out" of different portions of the data field. In one embodiment of the present invention, a particular piece of data within the broad data field can be accessed. First, the scale is selectively varied, thereby controlling a range within the data field. Then, the range is moved to encompass portions of the data field in which the piece of data resides. Next, the scale is successively decreased while, simultaneously, points successively closer to the location are kept with the range. The scale is decreased (i.e., increasing the range's resolution) and the range is moved in this manner until the piece of data is actually accessed.

A method for segmenting digitized images includes providing a training set comprising a plurality of digitized whole-body images, providing labels on anatomical landmarks in each image of said training set, aligning each said training set image, generating positive and negative training examples for each landmark by cropping the aligned training volumes into one or more cropping windows of different spatial scales, and using said positive and negative examples to train a detector for each landmark at one or more spatial scales ranging from a coarse resolution to a fine resolution, wherein the spatial relationship between a cropping windows of a coarse resolution detector and a fine resolution detector is recorded.

System and method for incorporating user input on the fly during an otherwise automatic registration process. During rigid registration, user input adjusts the current computed pose or transformation that relates the two images being aligned. During warping, user input adjusts the flow field locally, and is gradually smoothed into the surrounding flow field. During multi-scale registration where images are first aligned at a course resolution, and subsequently at progressively finer resolutions, user input is applied at the current scale. User input is detected during the automated process either by interrupts or polling. Between user inputs the registration results are re-rendered.

Disclosed is a fine resolution pulse width generator for use in a multiphase pulse width modulated voltage regulator. The fine pulse width is generated by first generating a pulse with a coarse pulse width and one or more delayed replicas thereof. Then, digitally controlled analog interpolators are used to generate the fine resolution pulse width pulse by interpolating among the coarse pulse width pulses. Both single edge and double edge modulation embodiments are disclosed providing interpolation of just the trailing edges of the coarse pulses or both the leading and trailing edges, respectively. The disclosed fine resolution pulse generator uses counters, thermometer encoders and analog interpolators to achieve interpolation accurately by insuring that each interpolation step corresponds to an equal weight. Accuracy of the interpolation is defined by the linearity (i.e. how well the interpolation fits a best fit straight line) and monotonicity (i.e. how each step contributes a positive weight to the total).
