retrovision-system RV4

Proposal to sustitute Mirrors with Retro-C谩maras and Displays LCD / RV.4 Weiss Design / Spain 路 2008

Intro Cuándo aparco mi automóvil en la vía pública (por ejemplo al lado de la acera o en un aparcamiento), los espejos retrovisores en el exterior de las puertas corren el riesgo de ser alcanzados por otros vehículos que pasan demasiado cerca. Después de haber sufrido repetidas roturas de espejos (multa incluida), me propuse buscar una manera de sustituir los espejos aprovechando los avances en la tecnología digital

Propuesta: La propuesta consiste en reemplazar los espejos grandes por videocámaras pequeñas y discretas, conectadas a monitores colocados en el tablero dentro del campo de visión del conductor

Objetivo: Evitar los peligros y molestias ocasionados por la rotura de los espejos retrovisores.

Funcionamiento: Las cámaras se colocan en el lado izquierdo + derecho exterior y en la zona central trasera (interior o exterior) del vehículo, pudiéndose regular su orientación y ángulo de vista desde el conductor. Tres monitores (displays LCD) agrupados encima de los instrumentos del tablero transmiten las imágenes al conductor, pudiéndose ajustar su luminosidad, contraste y dirección.

Beneficios: Las cámaras, por su tamaño pequeño y discreto, son poco expuestas a roturas e interferencias climáticas. Las tres imágenes de retro-visión sobre el volante hace al conductor más consciente del entorno y le permite, casi sin desviar la mirada, averiguar si puede hacer un cambio de carril

Comentarios: Es posible que los actuales displays sean todavía demasiado caros y su calidad de imagen no sea todavía suficiente para garantizar la seguridad del sistema propuesto. Pero la evidente evolución de esta tecnología permite suponer que pronto alcanzarán las cualidades necesarias y bajarán sus costos. Prueba de ello es el fuerte crecimiento de negocio en este sector que, según los pronósticos de los expertos, se duplicará en los próximos 6 años (ver artículo siguiente)

Automotive displays see continuous growth Written by Christoph Hammerschmidt http://www.esemagazine.com

Despite the ongoing recession in the automotive market, the market for automotive displays remains hot, featuring high growth rates over the next years, says DisplaySearch.

In its current Automotive Display Report, the Austin, Texas, based market researcher predicts that in 2009, about 175 million displays will be built, representing a value of $1,77 billion. In 2015, the market researchers believe the industry will achieve revenues of $2.4 billion on a production of 231 million units.

The strongest growth will be seen in the segment of automotive monitors —activematrix LCDs and typically featuring sizes larger than 15 centimeters (6 inches).

These displays will be used predominantly for navigation applications. For 2009, about 41 percent of these displays will have touch screens.

.

For this part of the market, DisplaySearch forecasts the market volume to grow to 34.4 million units in from 16.6 million units in 2009. The value of these shipments will increase by 51 percent to $1.56 billion in 2015. Driving forces in this market segment are demand for in-console displays for navigation and entertainment purposes. While DisplaySearch sees rising demand for fixed incar monitors, the experts believe the demand for portable navigation devices will shrink at a CAGR of 3.9 percent during the time frame in question.

Another major market segment are displays used as indicator, dials and gauges.

While this segment is predicted to grow from about 160 million units in 2009 to about 200 million units in 2015, the value of these displays will be almost constant at $800 million over the next six years.

Among the vendors, TMDisplay is the 500-pound gorilla with a market share of 38 percent, followed by Sharp with 31.4 percent. Other large vendors are AUO (9.7 percent), Epson (7.3 percent) and Optrex with 4.9 percent market share.

Optrex and Epson have dramatically increased their shipments in 2008, notes DisplaySearch.

The market is divided among relatively few buyers, with Panasonic, Continental, Pioneer, Fujitsu-TEN and Alpine accounting for more than half the units in recent quarters, the market researchers noted.

Conclusion: In the future, large wind-catching exterior rearview mirrors will most probaby be replaced with miniature rear-facing cameras that have no aerodynamic drag. These cameras will display what's behind you on interior monitors.

The small-sized cameras are less exposed to fracture and mal function. The three images combined n a monitor gives the driver a good feeling of what is happening behind.

Ideas Into Execution:

Giving Away An Idea To Make It Happen We spend a lot of time talking about innovation and ideas. Part of that discussion often turns to patents, and questions of whether it is better to "protect" or "hoard" your ideas, or to focus on sharing them. Patents live in this nebulous world between the two, where you partially (sort of) "give away" the idea, in exchange for the right to protect it. This seems counterintuitive when you think about it. Plenty of research has shown that people invent and innovate more often because they want what they're inventing themselves -- not because they want some sort of monopoly right over it. Other research has shown how innovation (rather than invention) is really an ongoing process, that often involves building on various ideas. For years, we've discussed how the "idea" is quite often overvalued, while the execution is undervalued. Lots of people have ideas. How you execute on them is where the real innovation occurs.
