Integrated delivery device for continuous glucose sensor

Systems and methods for integrating a continuous glucose sensor, including a receiver, a medicament delivery device, and optionally a single point glucose monitor are provided. Manual integrations provide for a physical association between the devices wherein a user (for example, patient or doctor) manually selects the amount, type, and / or time of delivery. Semi-automated integration of the devices includes integrations wherein an operable connection between the integrated components aids the user (for example, patient or doctor) in selecting, inputting, calculating, or validating the amount, type, or time of medicament delivery of glucose values, for example, by transmitting data to another component and thereby reducing the amount of user input required. Automated integration between the devices includes integrations wherein an operable connection between the integrated components provides for full control of the system without required user interaction.

Geometric calibration of head-worn multi-camera eye tracking system

A system and methods for geometric calibration and use of head-worn multi-camera eye tracking system are provided. The system calibrates the internal and external parameters of the cameras as well as the parameters of a compact geometric model of the human eye. An exo-camera determines a relative pose with regard to a computer monitor and endo-cameras determine the eyeball position and orientation. An endo-exo calibration and an endo-eye calibration each with an optimization step are included. A homography and a joint optimization step are also provided. A single point calibration re-establishes calibration. The system in operational mode determines a user's gaze direction to perform a computer input function.

Method and apparatus for building and using multi-dimensional index trees for multi-dimensional data objects

A method and apparatus are provided for building a searchable multi-dimensional index tree that indexes a plurality of data objects. In one aspect of the invention, the index tree divides dataspace into three subspaces and indexes the data objects using a single dimension. If too many data objects map to the same point in that dimension, the dimension is switched to a new dimension of the data object and the data object is indexed using the new dimension. A split node having a split value is used to keep track of the indexing. In another aspect of the invention, the index tree divides dataspace into two subspaces, and equal bits are used in the split nodes to track the content of the data objects in the subspaces. If too many data objects sharing the same key within the same dimension map to a single point, then the dimension is switched to a new dimension and the data objects are indexed using the new dimension. Also disclosed is the multi-dimensional index tree itself as well as a router that uses the multi-dimensional index tree of the present invention to provide packet classification functions.
