Abstract: Disclosed herein is an electronic luggage locking device and airline baggage handling method mainly characterized by ease-of-use, enhanced security and efficiency by utilizing proximity access-gaining and authentication technologies, a plurality of sensors, embedded electronic storage and retrieval of luggage information. The luggage locking device is incorporated with an electronic communication system enables interactions with other sensor modules within the luggage, external smart devices and airline transport systems to form an unitary baggage handling system. The baggage handling system contents a method using application software and capable of indicating and communicating the said luggage information and locational identification within an airline transport systems.

Abstract: Disclosed herein is an electronic combination lock mainly characterized by miniature size and easy-to-use electronic identification access-gaining method that enables a vast variety and type of access codes for user setting and choice. Another battery operated electronic key unit, incorporated with programmed access code to provide as an alternative choice for locking, unlocking and backup power, can be used in conjunction with the electronic combination lock.

Abstract: The invention relates to a method for calibration of 2-axis high precision digital angle measurement device, particularly for initializing a planar angle measuring device and an apparatus to generate simultaneous two-dimensional resultant planar angles of full 360° rotation. The planar angle measurement device is, typically but not exclusively, used in concurrent two-dimensional angles leveling, setting and alignment tasks for precision machine setup in the fields of precision engineering and metrology applications.
