Timing control in a specialized processing block
The tension between fmax and Tco in a specialized processing block of a programmable integrated circuit device can be reduced by providing variable delays on the clock inputs of the pipeline registers within the specialized processing block. This allows the introduction of beneficial skew that allows slower functions to be performed within the specialized processing block rather than outside the block, thereby reducing Tco, without slowing down the clock—i.e., without reducing fmax. This technique may also apply to other specialized blocks such as memory.

Method and apparatus for progressively selecting features from a large feature space in statistical modeling
Embodiments of a progressive feature selection method that selects features in multiple rounds are described. In one embodiment, the progressive feature selection method splits the feature space into tractable sub-spaces such that a feature selection algorithm can be performed on each sub-space. In a merge-split operation, the subset of features that the feature selection algorithm selects from the different sub-spaces are merged into subsequent sets of features. Instead of re-generating the mapping table for each subsequent set from scratch, a new mapping table from the previous round's tables is created by collecting those entries that correspond to the selected features. The feature selection method is then performed again on each of the subsequent feature sets and new features are selected from each of these feature sets. This feature selection-merge-split process is repeated on successively smaller numbers of feature sets until a single final set of features is selected.

Method for placement of sensors for surveillance
A limited number of sensors are placed at selected locations in order to achieve equitable coverage levels to all locations that need to be monitored. The coverage level provided to any specific location depends on all sensors that monitor the location and on the properties of the sensors, including probability of object detection and probability of false alarm. These probabilities may depend on the monitoring and monitored locations. An equitable coverage to all locations is obtained by finding the lexicographically largest vector of coverage levels, where these coverage levels are sorted in a non-decreasing order. The method generates a lexicographic maximin optimization model whose solution provides equitable coverage levels. In order to facilitate computations, a nonlinear integer optimization model is generated whose solution provides the same coverage levels as the lexicographic maximin optimization model. Solution of the nonlinear integer optimization model is obtained through the adaptation of known optimization methods.

Enhanced signal processing for cochlear implants
The restoration of melody perception is a key remaining challenge in cochlear implants.

To enable devices to detect L3 roaming users and to take appropriate forwarding actions, L3 knowledge is introduced inside a bridge in a non-intrusive way. In particular, as a client moves from a subnet associated with a first network element to a subnet associated with a second network element, a determination is made regarding whether the client is roaming.
