Abstract: The beverage appliance of the present invention includes a venturi having a steam inlet and a milk inlet. The steam inlet and milk inlet each include a solenoid valve configurable between an open state and a closed state. The solenoid valves are electrically coupled to a processor and are controllable through first and second switches. In operation, upon activation of the first switch, the solenoid valves are controlled to their open states to deliver milk and steam to the venturi to produce frothed milk. When a desired amount of frothed milk has been dispensed, the user deactivates the first switch and the processor controls only the milk inlet solenoid valve to its closed state. The steam inlet solenoid valve remains in its open state for a predetermined amount of time such that a burst of steam only is forced through the venturi and distribution lines to purge them of milk.

Abstract: An apparatus and a method for optically scanning a surface of an object under an adverse external condition to which optical components are subjected, such as cameras and lighting sources sensitive to soiling, make use of a first imaging sensor unit having its optical components subjected to the adverse external condition, and being configured for generating reflection intensity image data associated with a target surface. A second imaging sensor unit having its optical components substantially not subjected to the adverse external condition, is configured for generating reflection intensity image data associated with a reference surface. Correction data are calculated from a comparison between the reflected intensity image data associated with the target and reference surfaces, which correction data are then applied to the reflected intensity image data associated with the target surface to generate corrected intensity image data compensating for the adverse external condition.

Granted: 2022-08-30
Abstract: The overall quality of a workforce is analyzed, scored and presented using an analysis engine that performs a multi-domain analysis on enterprise data. The analysis engine presents key information about the performance of a workforce across a range of hardware devices so as to inform different users in their unique contexts and roles within a business organization as to workforce performance. The analysis engine associates a customizable performance profile with each workforce member. Each performance profile is comprised of a plurality of performance measures. Each performance measure in turn, represents a performance metric that measures some aspect of the job duties performed by the associated workforce member, e.g., an industrial vehicle operator. The scores are aggregated into an overall performance profile score. To compute the scores, data is considered across multiple domains, e.g., by collecting and analyzing data from industrial vehicle data systems, warehouse management systems, labor management systems, etc.

Inventor: HARPER MARK
IPC: G01V1/38
Filed: 2013-02-28
Granted: 2023-03-21
Abstract: There is provided herein a method of seismic acquisition that utilizes an arrangement of marine sources where each source is positioned at a water depth shallow enough for the surface ghost notch to fall at a frequency greater than or equal to the maximum radiated frequency of interest. If the marine seismic source has a ratio of signal bandwidth to maximum frequency that is less than one half, then it is possible to deploy it at a greater depth at which ghost notches fall below and above its frequency band but not in it. Further, by placing two or more sources at different depths for the same frequency, any undesired nulls in the radiation pattern caused by the deeper tow can be filled in.
