Abstract: A system and a method for estimating readiness for passing an associated summative assessment includes, after receiving test results for at least one test, generating a score Cn for each concept tested on the test. Using the score, the system computes a probability of mastery p(Mn) of the at least one concept and associates the probability of mastery p(Mn) as a prior for updating the probability after receiving future test results. The system iteratively updates the probability of mastery p(Mn) of the at least one concept after each test using for the new test score and the prior.

Abstract: A store profile generation system includes a mobile base and an image capture assembly mounted on the base. The assembly includes at least one image capture device for acquiring images of product display units in a retail environment. A control unit acquires the images captured by the at least one image capture device at a sequence of locations of the mobile base in the retail environment. The control unit extracts product-related data from the acquired images and generates a store profile indicating locations of products and their associated tags throughout the retail environment, based on the extracted product-related data. The store profile can be used for generating new product labels for a sale in an appropriate order for a person to match to the appropriate locations in a single pass through the store.

Abstract: A method of operating a printer includes identifying a region of a print medium located between marks formed by a first plurality of inkjets in the printer and an edge of the print medium. The printer activates a second plurality of inkjets to print ink drops into the region during a printing operation. The method enables full-bleed or near full-bleed printing for different media sizes.

Abstract: Direction and speed of robotic data acquisition systems engaged in acquiring data in mapped or route-planned environments, and/or environments having reference features (e.g., shelves, walls, curbs or other structure) enabling additional guidance and control, are disclosed. A mobile base can include wheels adapted to navigate an environment. At least one sensor (e.g., imaging camera, acoustic, passive infrared, etc.) can be mounted on the mobile base and acquires data (e.g., images) of items associated with or located along fixed structures defining the pathways within the environment. A computer can control mobile base movement and orientation with respect to the at least one structure utilizing range sensors and PID controllers, track mobile base location, and organize acquired data. Range sensors under the control of the at least one computer can be adapted to control mobile base movement in a straight line and at a constant speed with respect to a fixed structure.
