50 to 200 A Integrated Conductor Sensor ICs

ACS756 Fully Integrated Hall Effect-Based Linear Current Sensor

"The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer."

PICMG - Open specifications for Modular Computing

PICMG is a consortium of companies who collaboratively develop open specifications for high performance telecommunications and industrial computing applications.

PICMG - Open specifications for Modular Computing

Specs and Standards for Advanced Mezzanine Card, AdvancedTCA, COM Express, CompactPCI, e-PCI-X, MicroTCA and others.

PCI-ISA - Passive Backplanes

(Study this page first to understand how computers became more maintanable and expandable - delabs)

PCI-ISA - Passive Backplanes

"The PCI-ISA passive backplane standard moves all of the components normally located on the motherboard to a single plug-in card. Looking much like a standard ISA or PCI card, a PCI-ISA CPU card has two edge connectors on it - one for the PCI bus and one for the ISA bus. The "motherboard" is replaced with a simple "passive backplane" that has only connectors soldered to it."

NAND Flash Interface and ONFi

Open NAND Flash Interface - Made up of more than 80 companies that build, design-in, or enable NAND flash memory. This is used mainly as a storage component in many small devices. (boot, firmware/OS and Data).Standardizing the NAND Flash interface.

NAND Flash Interface and ONFi

ONFI's parameter page provides the controller with all of the device's relevant capabilities for quicker design, qualification, and testing.

ONFI's industry-standard BGA package accommodates both asynchronous and source-synchronous interfaces.

NAND Flash Interface and ONFi

Higher Speeds At 400 MB/s, ONFI is the fastest NAND interface standard on the planet. These high speeds are made possible by the bidirectional source-synchronous DQS and scalable I/O interface.

ONFI 3  Announced in March of 2011

Promotes a high-speed NAND Flash interface supporting transfer rates up to 400 MB/s - requires fewer chip enable pins enabling more efficient PCB routing - designed for the future and supports the EZ-NAND interface

USB.org - Universal Serial Bus and Wireless USB

USB.org - Universal Serial Bus

Universal Serial Bus (USB) connects more than computers and peripherals. It has the power to connect you with a whole new world of PC experiences.

USB Implementers Forum, Inc. is a non-profit corporation founded by the group of companies that developed the Universal Serial Bus specification.

Wireless USB - Wireless Extension to USB

Wireless USB is the first high-speed wireless personal interconnect technology to meet the needs of multimedia consumer electronics, PC peripherals, and mobile devices.

Wireless USB performance is targeted at 480Mbps at 3 meters and 110Mbps at 10 meters.

Wireless USB Software and Hardware Tools

2008

I had to put some files from my USB ThumbDrive to iPod. That needed a Turn on, on my computer and then plugging things on, and a transfer.

I saw this innovation earlier. Wireless USB - Wireless Extension to USB. And also a USB Drive like product.

I feel this type of thing can be made for stand alone iPod, extra storage or archive. No need to turn on PC.

Also, i think, there may be a need (?), for a very small, tiny Wi-Fi Router with 100 GB storage, media and cache management. That can serve 2 or 3 iPods and 1 or 2 Netbooks.
