Multi-Function Adaptive Simulation Cartridge And Method

View page
US Patent:
20200141685, May 7, 2020
Filed:
Aug 24, 2019
Appl. No.:
16/550186
Inventors:
Philip S. Liu - Walnut Creek CA, US
Chi-Chang Liu - Walnut Creek CA, US
Assignee:
Guidance Education Technologies Inc. - Pleasant Hill CA
International Classification:
F41A 33/02
F41A 31/02
Abstract:
A simulation laser training cartridge for dry-firing practice adapts to the wear condition of a given firearm and provides a convenient way of measuring the barrel erosion. The cartridge uses multiple adjustable interfacing parts that can be applied selectively and independently according to the condition of the barrel to ensure a snug fit in 3-dimensions. In a 2-unit kit embodiment of the invention, the muzzle unit can work with multiple chamber units for a multi-chamber firearm. The cartridge also includes internal modules for laser property management, status monitoring, movement tracking, memory, and communication to help a user manage the device and allow for advanced training applications. By changing the laser property, the laser training cartridge can work as a bore sight. The cartridge may further include a means to attach an external part, so the external part comprises a means to distinguish a longitudinal position inside said barrel.

US Patent:
20150104778, Apr 16, 2015
Filed:
Oct 10, 2014
Appl. No.:
14/512333
Inventors:
CHI-CHANG LIU - Concord CA, US
PHILIP LIU - Concord CA, US
International Classification:
G09B 7/04
G09B 5/08
G09B 5/02
US Classification:
434335, 434353
Abstract:
A computerized interactive learning system includes a display device and a compatible input device. The display device provides work items to a learner. The input device detects input activities from the learner in response to the work item. The system analyzes the input activities at two or more tiered levels of granularity. The display device provides conditional feedback to the learner based on the analysis. The input device and the display device can be incorporated into an integrated touchscreen.
