Abstract: A system may include one or more finger-mounted devices such as finger devices with U-shaped housings configured to be mounted on a user's fingers while gathering sensor input and supplying haptic output. The sensors may include strain gauge circuitry mounted on elongated arms of the housing. When the arms move due to finger forces, the strain gauge circuitry can measure the arm movement. The sensors may also include ultrasonic sensors. An ultrasonic sensor may have an ultrasonic signal emitter and a corresponding ultrasonic signal detector configured to detect the ultrasonic signals after passing through a user's finger. A two-dimensional ultrasonic sensor may capture ultrasonic images of a user's finger pad. Ultrasonic proximity sensors may be used to measure distances between finger devices and external surfaces. Optical sensors and other sensors may also be used in the finger devices.

Abstract: Small molecule analytes (less than 1000 Daltons) in a fluid sample are detected using a competitive assay in a magnetic biosensor. The fluid sample is added to a biosensor detection chamber together with detection probes and magnetic tags which bind to the detection probes. The magnetic biosensor is functionalized with a capture probe that shares an epitope with the analytes, and the detection probe is capable of binding the epitope shared by the analytes and the capture probe, so that the presence of the analyte prevents detection probes (and magnetic tags) from binding to the biosensor. By measuring the binding of the magnetic tags to the magnetic biosensor, an amount of analytes in the solution is determined.

Abstract: As part of a technique for positioning viewports over interactive digital maps, a digital map of a geographic area is provided via a user interface of a computing device. The currently visible portion of the digital map is displayed in a viewport. A user gesture is detected, where the user gesture communicates a particular acceleration to the viewport, along a particular direction, to move the viewport from its current position to a target position over the digital map. A current user context for the digital map is determined. A new position of the viewport over the digital map is determined in accordance with (i) the user gesture and (ii) the current user context, such that the new position is different from the target position, and the viewport is moved from its current position to the new position.
