Toshiba Colabora en el Desarrollo de CI para Sistemas Inalámbricos

Toshiba Corporation (TOKIO: 6502) anunció hoy que la compañía está colaborando con Hanrim Postec LLC (Hanrim) en el desarrollo de circuitos integrados (CI) para sistemas inalámbricos. Las compañías están trabajando en CI y sistemas basados en el estándar Qi*1 especificaciones de baja potencia para dispositivos celulares, que incluyen los teléfonos inteligentes y los celulares, según la propuesta del Consorcio de Energía Inalámbrico (Wireless Power Consortium)*2 (WPC).

Toshiba y Hanrim ingresarán, este mes, al mercado celular con un sistema de carga sin contacto. Toshiba ha desarrollado y fabrica los CI para el sistema, y Hanrim proporciona el módulo.

La demanda por teléfonos inteligentes está creciendo rápidamente, al igual que su uso, ya que más y más personas se basan en ellos como una plataforma de mensajería y para acceder a Internet. Como resultado, suele ser necesario cargar los teléfonos inteligentes dos veces al día, a veces incluso más, lo que obliga a los usuarios a llevar siempre consigo el cable de carga. Esto significa una demanda estimulante por un nuevo sistema de carga, sin contacto ni cable, que ofrece mayor conveniencia y facilidad de uso.

Toshiba ha desarrollado dos productos de acuerdo con el estándar Qi utilizando los sistemas de carga sin contacto de Hanrim. Los envíos de muestras comenzarán en diciembre.

*1:   Estándar Qi
Un estándar de transferencia inductiva para aplicaciones de baja energía, estandarizado de 0 a 5W.
*2: WPC
Según datos de este mes, WPC contaba con un total de 137 compañías miembro, un claro reconocimiento que ha establecido el estándar de factor mundial para sistemas inductivos sin contacto, con compañías que trabajan en sistemas de energía y receptores de energía compatibles con el estándar Qi.
Toshiba se unió a la WPC en febrero y ha estudiado meticulosamente el estándar para el desarrollo de CI para sistemas de carga sin contacto. Hanrim también es miembro.

TB6865FG

Transmisor de energía

Diciembre de 2012 Enero de 2013 Cumple con el estándar Qi versión 1.0
TB6860WBG

Receptor de energía

  Diciembre de 2012   Enero de 2013   Cumple con el estándar Qi versión 1.0
 

Características

1.  

Cumple con el estándar Qi de WPC versión 1.0

 
2. Se usa un convertidor DC-DC integrado para carga y alimentación de energía.
Para el receptor de energía TB6860WBG el convertidor DC-DC se usa para la tensión de salida. Salida de capacidad de corriente de 1.200 mA (máx.) garantiza una carga rápida.
 
3. Incluye la función de carga de batería.
El TB6860WBG tiene un modo de alimentación de energía que alimenta el sistema de carga si la plataforma está en carga. También tiene un modo de cargo para cargar la batería directamente. Si se incluye un sistema de carga sin contacto en la batería de un dispositivo celular, la aplicación del TB6860WBG reduce el uso de CI especiales para carga. Puede reducir el tamaño y el costo. El registro incluido puede crear un perfil de carga único para baterías de distintas compañías.
 
4. Carga dos dispositivos simultáneamente.
El TB6865FG puede cargar dos dispositivos simultáneamente. Mientras se carga un teléfono inteligente con la marca Qi, se puede cargar otro dispositivo celular (cámara fija digital, consolas de juego celulares, etc.) con la marca Qi al colocarlo en la almohadilla de transmisión. La almohadilla en carga puede soportar dos dispositivos celulares "Qi". No requiere un cable especial.

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...
Data is an unusual currency; it is not restricted by the same transactional limitations as money or people. In fact, the more that you leverage your data across multiple business use cases, the more valuable it becomes to the organization. And the same can be said about the organization’s analytics. In his session at 19th Cloud Expo, Bill Schmarzo, CTO for the Big Data Practice at EMC, will introduce a methodology for capturing, enriching and sharing data (and analytics) across the organizati...
The vision of a connected smart home is becoming reality with the application of integrated wireless technologies in devices and appliances. The use of standardized and TCP/IP networked wireless technologies in line-powered and battery operated sensors and controls has led to the adoption of radios in the 2.4GHz band, including Wi-Fi, BT/BLE and 802.15.4 applied ZigBee and Thread. This is driving the need for robust wireless coexistence for multiple radios to ensure throughput performance and th...
Information technology is an industry that has always experienced change, and the dramatic change sweeping across the industry today could not be truthfully described as the first time we've seen such widespread change impacting customer investments. However, the rate of the change, and the potential outcomes from today's digital transformation has the distinct potential to separate the industry into two camps: Organizations that see the change coming, embrace it, and successful leverage it; and...
I'm a lonely sensor. I spend all day telling the world how I'm feeling, but none of the other sensors seem to care. I want to be connected.

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
