Abstract: Disclosed are methods and apparatus for capturing information that is pertinent to physical surroundings with respect to a device, the information including at least one of visual information or audio information. Overlay information for use in generating a transparent overlay via the device is obtained using at least a portion of the captured information. The transparent overlay is then superimposed via the device using the overlay information, wherein the transparent overlay provides one or more transparent images that are pertinent to and in correlation with the physical surroundings.

Abstract: Disclosed are methods and apparatus for implementing a reality overlay device. A reality overlay device captures information that is pertinent to physical surroundings with respect to a device, the information including at least one of visual information or audio information. The reality overlay device may transmit at least a portion of the captured information to a second device. For instance, the reality overlay device may transmit at least a portion of the captured information to a server via the Internet, where the server is capable of identifying an appropriate virtual billboard. The reality overlay device may then receive overlay information for use in generating a transparent overlay via the reality overlay device. The transparent overlay is then superimposed via the device using the overlay information, wherein the transparent overlay provides one or more transparent images that are pertinent to the physical surroundings.

Abstract: A sensor kit comprising a sensor for detecting an analyte, a sensor housing and a calibration chamber. The calibration chamber comprises a first compartment containing a first calibration solution and a second compartment containing a source of the analyte to be detected. A dividing material is located between the first and second compartments enabling them to be mixed on breakage or removal of the dividing material. Further compartment(s) containing further source(s) of the analyte may optionally be provided. Calibration can carried out by (a) taking a reading of the analyte concentration of the first calibration solution, (b) mixing the contents of the first and second compartments by breaking or removing the dividing material, and (c) taking a reading of the analyte concentration of the resulting mixture. Steps (b) and (c) can be repeated for further compartment(s) to provide further reading(s) if desired.
