Patent number: 8537562Abstract: Manufacture of electronic devices is usually accomplished through automated assembly lines using automated conveyors. These automated conveyors, typically comprising metallic components, cannot convey electronic devices into an RF chamber for testing (e.g., RF) during manufacture without compromising the efficacy of the shielding provided by the RF chamber. Thus, although electronic devices are assembled on automated assembly lines, a device is typically removed from the automated assembly line for testing, transported manually into an RF chamber, powered on, and then tested. After testing, the electronic device is powered down, manually removed from the RF chamber, and returned to the assembly line. Described herein are embodiments of a system and method to automatically transport electronic devices under power through an RF isolated chamber for testing (e.g., RF) as part of an automated assembly line process resulting in a dramatic increase in the number of electronic devices that can be tested.Type: GrantFiled: September 25, 2012Date of Patent: September 17, 2013Assignee: Paradigm Circuit Solutions Inc.Inventors: Neil D.

Patent number: 8444310Abstract: A LED module with fast disassembly function is capable of being disassembled from a hole of a substrate by a tool and includes a lamp base, a LED and fasteners. The lamp base has tabs extending outwards. Each of the tabs is provided with a through-hole corresponding to the hole. The tab is formed with an inclined surface at the periphery of the through-hole. The LED is fixed on the lamp base. Each of the fasteners has a cap. The fastener is disposed through the hole and the through-hole to be fixed thereto. A notch is formed between the cap and the inclined surface. The tool is disposed in the notch to thereby disassemble the fastener from the hole and the through-hole. With this arrangement, the damaged LED can be detached from the substrate rapidly without replacing the whole LED module, thereby reducing the time and cost for maintenance.Type: GrantFiled: August 17, 2010Date of Patent: May 21, 2013Assignee: Amphenol LTW Technology Co., Ltd.Inventors: Chang-Nan Chen, Teng-Sheng Hung, Jen-Yuan Hung
