Abstract: An infant gastrointestinal monitor and a method for infant gastrointestinal monitoring are provided. The infant gastrointestinal monitor includes a belly band for placing around at least a midsection area of a subject infant. The infant gastrointestinal monitor further includes a plurality of wireless sound sensors, integrated with the belly band in an array configuration, for identifying a location of a gastrointestinal noise in the subject infant based on cross-referencing signals from the plurality of wireless sound sensors. He infant gastrointestinal monitor also includes a controller, operatively coupled to the plurality of wireless sound sensors, for analyzing the location and one or more other parameters of the gastrointestinal noise to identify a probable cause of the noise and a recommended action for a caregiver to alleviate an underlying condition causing the noise.

Abstract: A self-cleaning sensor to determine a level of a liquid includes a tube with an interior coating and a plurality of horizontally aligned, electrically isolated, electrical contacts. The self-cleaning sensor includes the plurality of horizontally aligned, electrically isolated, electrical contacts that each terminate in an outer surface of an interior wall of the tube and are electrically connected to one or more electrical devices in a cap residing on the tube. Additionally, the self-cleaning sensor includes a float that is composed of a low density, low dielectric constant material buoyant in one or more liquids to be measured where each horizontal dimension of the float corresponds to each horizontal dimension of the tube.

Abstract: A method for enhanced digital content presentation is provided that includes assigning, to each member of members of a social network of a user, a respective knowledge score, the knowledge score being representative of accuracy in the member predicting positive impressions of the user. The members of the social network are surveyed for an indication of which one or more options for digital content are expected to have a positive impression on the user. Based on the surveying, selected digital content based on the one or more options that are expected to have a positive impression on the user, as indicated by the surveying, is selected. The selected digital content is presented to the user. An indication of whether the selected digital content had a positive impression on the user is received from the user.

Abstract: An optical sensor and a deformation detection system in which the optical sensor is used. The optical sensor includes an optical fiber, an elongated hollow housing having an interior portion, and a material disposed on an inner surface of the housing that produces a persistent change in an optical signal transmission property of the optical fiber when the optical fiber contacts the material. The optical fiber elastically extends between opposing ends of the housing such that a bending deformation of the housing beyond a threshold radius of curvature causes a contact to occur between the material and the optical fiber. The contact results in persistent change in the optical signal transmission property of the optical fiber, which can be detected to determine whether deformation of the device occurred beyond a predetermined threshold value. The deformation detection system can use one or more of the optical sensors attached to the device.
