Filed:

Apr 11, 2017

Appl. No.:

15/484434

Inventors:

Dinh Le - Rosemead CA, US

International Classification:

F16C 11/12
E05D 1/00

Abstract:

A detent living hinge can rotate freely, can flip open/close, and has detent mechanism for holding the connected components firmly in designated open/closed positions. The hinge's thin flexible strip adheres to the hinge component connectors and lets them rotate about the hinge axis. The hinge spring pulls the component connectors close together to their intended positions to keep the thin flexible strip from collapsing or getting overly stretched and twisted.

Abstract:

An m-by-n switch array comprises a frame, switches that anchor around the frame, and threads that connect the switches to their opposing sides of the frame. Applying pressure on a thread pulls the switch, connected to that thread, to its ON state and releasing pressure on the thread lets the switch, connected to that thread, bounces back to its natural OFF state. Applying pressure on an intersection of two threads pulls the two switches, that connected to the two intersected threads, to their ON states while releasing pressure lets those two switches bounce back to their natural OFF states. The position of the intersection, where pressure is applied, can be determined by checking the ON/OFF states of all the switches. Keys can be placed on the thread intersections to emulate devices such as keypads, calculators, remote controls, keyboards, and other key input devices.
