Patent number: 11961416Abstract: Systems and processes are provided for analyzing a test taker's knowledge, skills, and cognitive function. The systems and processes include smart questions (i.e., SmartItems) programmed with coded variables, or for multiple choice varieties, variable sets of options to cover an entire skill set being tested. The systems and processes generate questions in real time during administration of the test, by formulating and displaying, to a test taker, random combinations of a question stem and randomly-selected question components. This smart question content is unpredictably and randomly presented, as representations of the skill to be tested. The systems and processes analyze the test taker's knowledge, skills, and cognitive function about the entire domain of the skill, rather than a single fact. The systems and processes provide security to test administration.Type: GrantFiled: June 8, 2022Date of Patent: April 16, 2024Assignee: Caveon, LLCInventors: David Foster, Nat Foster

Publication number: 20230222934Abstract: A system and process for dynamic security monitoring of test taking. The system combines historical information about the test taker or relevant conditions, and includes sensors which objectively monitor test taker's actions, inactions, and involuntary response to the test given before and during the test, and at a specific test location. The information collected from the sensors is compared to a plurality of predetermined individual risk factors, which indicate a possibility of test fraud by the individual test taker to create a test event risk profile. The individual risk profile is combined with non-individual specific risk factors to create a holistic test event security profile. Security resources are then dynamically assigned to or removed from the test event based on the unique test event security profile.Type: ApplicationFiled: March 20, 2023Publication date: July 13, 2023Applicant: Caveon, LLCInventors: David Foster, Steve Addicott

Patent number: 11448477Abstract: Provided are multi-mode firearms, triggers, kits, and methods of use that allow a user to select between a semi-automatic firing mode and a pull-and-release firing mode that fires the firearm upon both pulling the trigger and releasing the trigger, by using the selector switch or other mechanism to change the amount the trigger can move. A safe mode that prevents the firearm from firing may also be selected in various example embodiments by using the selector switch or other mechanism to change the amount the trigger can move. In certain example embodiments the trigger cannot move at all in safe mode, can move more in semi-automatic mode, and can move yet more in pull-and-release mode. The modes can be positioned for selection in any order. Kits comprising a trigger assembly and a selector assembly are provided for retrofitting conventional semi-automatic firearms.Type: GrantFiled: January 20, 2020Date of Patent: September 20, 2022Assignee: FOSTECH, INC.Inventor: David Foster

Patent number: 11347821Abstract: A system to improve real-time generation of a graphical user interface for overlapping electronic content is described. The system retrieves, responsive to a search request input into a computing device and received via a computer network, places of interest from a places of interest database, and content items from a content item database. The system selects, based on a heuristic technique, a content item as a match for a place of interest. The system combines the content item with the place of interest to prevent a first marker of the content item from obscuring a second marker of the place of interest. The system renders, for display on the graphical user interface via the computing device, a single marker for the content item and the place of interest combined to prevent the first marker of the content item from obscuring the second marker of the place of interest.Type: GrantFiled: February 13, 2020Date of Patent: May 31, 2022Assignee: GOOGLE LLCInventor: Andrew David Foster
