Abstract: Tracking data of objects within a facility may be obtained using a plurality of smart floor tiles. Techniques for installation of the smart floor tiles allow for the generation of information about the relative arrangement of the smart floor tiles relative to one another. This relative arrangement is used in conjunction with information about physical dimensions of the smart floor tiles to generate a mapping that associates particular floor tiles with particular physical locations within the facility.

Abstract: A non-contact biometric identification system includes a hand scanner that generates images of a user's palm. Images are acquired using light of a first polarization at a first time show surface characteristics such as wrinkles in the palm while images acquired using light of a second polarization at a second time show deeper characteristics such as veins. Within the images, the palm is identified and subdivided into sub-images. The sub-images are subsequently processed to determine feature vectors present in each sub-image. A current signature is determined using the feature vectors. A user may be identified based on a comparison of the current signature with a previously stored reference signature that is associated with a user identifier.
