Patent number: 8870584Abstract: A card connector includes an insulative housing with a first card receiving space, a number of first contacts extending into the first card receiving space, a push-push mechanism and a stop wall. The push-push mechanism includes a slider, an elastic member for urging the slider and a locking arm fixed to the slider. The locking arm includes a hook for locking a first card and a resilient buffering member protruding forwardly beyond the slider. The stop wall is located adjacent to an insertion opening of the first card receiving space. The stop wall is capable of resisting against the resilient buffering member so as to slow down the first card when the first card is quickly ejected along the card extraction direction. As a result, the first card can be prevented from flying off the card connector.Type: GrantFiled: April 25, 2013Date of Patent: October 28, 2014Assignee: Kunshan Jiahua Electronics Co., Ltd.Inventor: Fei-Song Ma

Patent number: 8460742Abstract: Latent fingerprints on a porous substrate such as paper are developed for viewing and recordal by applying heat to cause the fingerprint to be clearly viewed under radiation to cause the fingerprint to fluorescence (e.g. a few seconds heating with hot air or client contact with a heated device at around 260° C.) and viewing under e.g. light of 200 nm to 550 nm with a filter in the yellow to orange wavelength region. Alternatively more extended heating can render the fingerprint assemble under ultraviolet light, and under yet more extended heating permits viewing under white light.Type: GrantFiled: November 28, 2008Date of Patent: June 11, 2013Assignee: University of Technology, SydneyInventors: Brian Reedy, Mark Tahtouh, Adam Brown, Di Fei Song, Daniel Sommerville, Ronald Shimmon
