  • Patent number: 8246911
    Abstract: Interactions between molecules that are components of self-assembled monolayers and other molecules can be amplified and transduced into an optical signal through the use of a mesogenic layer. The invention provides for a method for detecting an analyte, comprising contacting with said analyte a recognition moiety for said analyte, wherein said contacting causes at least a portion of a plurality of mesogens proximate to said recognition moiety to detectably switch from a first orientation to a second orientation upon contacting said analyte with said recognition moiety; and detecting said second orientation of said at least a portion of said plurality of mesogens, whereby said analyte is detected.

  • Publication number: 20120157127
    Abstract: Through status awareness, a handheld communications device may determine the location, activity, and/or physical or emotional state of the user. This information may in turn be used for various purposes, such as 1) determining how to alert the user of an incoming communication, 2) determining what format to use for communicating with the user, and 3) determining how to present the user's status to another person's communication device.

  • Patent number: 7970573
    Abstract: A method, apparatus, and article containing computer instructions are described. Embodiments may use accelerometer data regarding forward motion by a wearer of a three-axis on-body accelerometer. Embodiments may further measure an acceleration due to gravity on each axis x, y, z of the accelerometer and use the direction of gravity to associate or align the x axis of the accelerometer with gravity. Embodiments may then use the acceleration not due to gravity to identify the forward motion and associate or align the forward direction with the y axis. The remaining direction may be identified as the sideways direction, which may be associated or aligned with the z axis. Additional activities may then be performed using the now-known orientation of the accelerometer. Other embodiments are described and claimed.

  • Patent number: 7947716
    Abstract: Compounds having two reactive functional groups are described that can be used to provide a connector group between a substrate and an amine-containing material. The first reactive functional group can be used to provide attachment to a surface of a substrate. The second reactive functional group is a N-sulfonylaminocarbonyl group that can be reacted with an amine-containing material, particularly a primary aliphatic amine, to form a carbonylimino-containing connector group. The invention also provides articles and methods for immobilizing amine-containing materials to a substrate.

  • Patent number: 7930379
    Abstract: The present disclosure provides a method for delay tolerant networking. According to one exemplary embodiment, the method may include transmitting a file from a first node associated with a first network to at least one intermediate node via a file-system interface. The method may also include receiving the file at the at least one intermediate node via the file system interface. The method may further include transmitting the file from the at least one intermediate node to at least one node of an additional network via the file-system interface and receiving the file at the at least one node of the additional network via the file-system interface. Of course, additional embodiments, variations and modifications are possible without departing from this embodiment.

  • Publication number: 20100332571
    Abstract: Methods, apparatuses and systems capture data related to a food item via one or more sensors and narrow the possible identities of the food item by determining the time when the data capture occurred and the location of the food item. A list of nodes based at least in part on the narrowed possible identities is generated to identify the food item and sorted based at least in part on the probability of one or more nodes corresponding to the food item.
