Piratean el logo del IMSS

By Pedro Santana on Friday, February 04, 2005


Me acabo de enterar que la empresa China, Giordon Audio Alarm Equipment, dedicada al comercialización de sistemas de seguridad y de audio para autos, esta utilizando tal cual el logotipo del Instituto Mexicano del Seguro Social. Solo modificaron el color, del verde original a rojo y agregándole una "R" de Marca registrada.

¿Qué les parece esto?

Ademas de que ya estan enterados, y esto es lo que contestaron:
Dear All,

Many thanks for inform us immediately about such embarrassing conflict! We really feel sorry about this!
We are an electronic product manufacturer established in year 1994, 2years after our establishment we invited an advertising company to design a logo for us, which should be related to our brand name EAGLE, an image of power and capability for our car alarm system. Then this logo was born and registered as our sole company logo till now. We were not notified even when we did registration in China and over 10 countries worldwide that this logo has been occupied. Our managing board would not choose this logo if know this logo is in use already. We admit we lack ability in our logo identification.
We must say thanks to all of you for your soonest information, especial Jaime who is the first one we receive message from on Jan.24 morning. From that moment, we tried to contact with that advertising company, unfortunately we were confirmed that company stopped running for years. We couldn't question them what's the matter with this logo.
But for sure, we, Giordon, never intend to use same logo as others, it's no good to our business. In the past 8years we spend a lot of time and cost in building our company image with this logo. We won't waste like this if we have been knowing the fact. As a capable manufacturer, we pay close attention to our image as much as our product quality.
We feel sorry that such unexpected coincidence actually happened to us! What we can do now is to hold any of our products with this logo from Mexican market. Although we will lose a lot from this action, we still have great willingness to protect IMSS's copyright in Mexico. We guarantee this!

Best regards,

Siemens digital graffiti o SMSs conscientes de la localización?

By Pedro Santana on Thursday, February 03, 2005
Siemens ha desarrollado algo que llaman graffiti electrónico y consiste en un sistema para poder anclar mensajes SMS a un determinado punto geográfico. Cuando la persona llega a ese punto recibe el mensaje.
In the future, mobile phone users will be able to leave messages anywhere in the form of what might be termed electronic post-its. They will be able to post virtual messages referring to a specific location wherever they are needed. Siemens researchers have now created the technical basis and the computer programs for this “digital graffiti service.” The Siemens Corporate Technology’s research laboratory in Munich under the directorion of Dieter Kolb developed computer programs that assign cell phone messages to specific locations. The user can leave a message, known as a digital graffito, at any geographical point. This is a kind of SMS attached to one spot. When the recipient reaches the defined point, the message appears on his or her display.
