Publication number: 20130299325Abstract: I (the applicant) have invented a method of quarantine computer virus, cross reference to related application Ser. No. 61/520,159, filing or 371(c) date Jun. 4, 2011. The “ON-ON MASTER SWITCH” controls the electrical voltage (12 Volt and 5 Volt power) to the hard drives at different time. For home use one hard drive (the left side, red led) would be installed with operating program, internet, e-mail and skype. The other hard drive ( on the right side, green led) would be installed with operating programs, Microsoft office, adobe, adobe photo shop, Autocad, income tax files, photos, family moves, etc. When you are surfing on the internet you can get a computer virus that will destroy your family photos, Autocad files etc. Or scan your computer and get your income tax files, banking information. With “ON-ON MASTER SWITCH” is on the left side your files are safe. For business use one hard drive would be used as primary drive and the other one would be used as a secondary backup.Type: ApplicationFiled: December 1, 2012Publication date: November 14, 2013Inventor: Andrew (Andrzej) Lewicki

Patent number: 8536476Abstract: An illuminated keyboard includes plural keys, a membrane switch circuit member and an illumination module. The illumination module is used for emitting plural light beams. When the membrane switch circuit member is triggered by depressing a key, the membrane switch circuit member issues a corresponding key signal. The membrane switch circuit member includes plural light-guiding zones. Each of the light-guiding zones is filled with the corresponding light-guiding layer, so that no vacant space is formed in the light-guiding zone. As a consequence, the light-guiding layer is structurally rigid, and the possibility of abrading the light-guiding layer is minimized.Type: GrantFiled: June 14, 2011Date of Patent: September 17, 2013Assignee: Primax Electronics Ltd.Inventor: Chung-Yuan Chen

Patent number: 8462022Abstract: A control unit comprising a light guide is formed and positioned in a circuit board for providing visual indication to a user of an appliance, such as a cooktop. The light guide receives light from a source, typically in the form of an LED on the circuit board, typically positioned laterally to the light guide, and the light guide receives and directs the light to the user. In some embodiments, the light guide is positioned behind a cover, which may have indicia thereon for providing operating information to the user. Portions of the light guide may be coated with an electrically conductive coating so as to also form a portion of a capacitance touch switch for detecting user input for controlling operation of the appliance.Type: GrantFiled: November 11, 2008Date of Patent: June 11, 2013Assignee: E.G.O.
