Abstract: A method for analyzing distribution of tolerances on a freeform surface in an optical system. Establishes a freeform surface imaging optical system. A plurality of fields is selected, and maximum and minimum margins of wavefront errors in each field are defined. One freeform surface in one field is selected, an isolated point jumping model is established, and an isolated point is placed in different areas of the freeform surface of the one field. A local figure error with extreme values corresponding to each field is resolved, based on the maximum and minimum margins of wavefront errors, and the local surface tolerance distributions of the freeform surface in the plurality of fields are integrated together.

Abstract: Systems and methods for testing and diagnosing malfunctions in a liquid dispenser are provided. In a general embodiment, the present disclosure provides a testing and diagnosing system including a pre-tester configured to test for and collect testing data regarding an operational status of the liquid dispenser and in communication with the liquid dispenser, a communication central module configured to receive information from the testing device and the pre-tester, and a database management system configured to operate, monitor and control the testing device, the pre-tester and/or the communication central module.

Abstract: A beverage preparation machine includes first and second cameras for capturing first and second images of a receptacle. The beverage preparation machine further includes a control unit configured to determine a receptacle volume based on the first and second images and to determine a beverage volume to be dispensed based on the receptacle volume and the selected filling level or percentage. Regardless of the shape, volume, and/or material of the receptacle, the filling level or percentage for dispensing the beverage can be freely selected via a user interface.

Abstract: A processor executes instructions stored in non-transitory memory to determine whether a query to big data is bounded evaluable, or may be rewritten to access a bounded amount of data or information in a dataset. A query plan may retrieve the information by using indices in access constraints of the query. The cost associated with obtaining the information by using the query plan may be dependent on the query and access constraints and not the size of the dataset. A query plan to obtain the information may be formed for different types or classes of queries, such as conjunctive queries (CQ), unions of conjunctive queries (UCQ) and positive existential FO (first order) conjunctive queries (?FO+). When a query is not bounded evaluable, a determination is made whether an approximation to the information may be retrieved. An approximation may be obtained by using upper and lower envelopes or specialized queries.

Abstract: A method for performing alarm grouping control of an electronic device and an associated apparatus are provided, where the method includes the steps of: shifting the execution timing of at least one alarm of a plurality of alarms to group the plurality of alarms into at least one grouped alarm according to at least one grouping control strategy, wherein the execution timing of the at least one alarm is shifted to the execution timing of the at least one grouped alarm; and according to the at least one grouped alarm, controlling whether to wake up at least a portion of the electronic device.
