Optical mouse sensor works on dodgy
surfaces
A new LED-based optical mouse sensor provides better tracking control than previous-generation LED-based devices.
Agilent Technologies has released an LED-based optical mouse sensor that provides better tracking control than the company's previous-generation LED-based devices The new sensor outperforms other optical mouse sensors by working over a wider variety of surfaces, including wood desktops and half-tone images

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
Only Agilent's revolutionary laser mouse technology introduced earlier this year works on more surfaces, due to its 20x improvement over LED-based devices in surface tracking accuracy.
The Agilent ADNS-3060 LED-based optical mouse sensor provides excellent tracking control for applications such as corded and cordless mice for desktop and game PCs, notebook PCs, trackballs and integrated input devices.
Compared with Agilent's widely used ADNS-2051 high-performance optical navigation sensor, the ADNS-3060 features 3.3V (rather than 5V) operation, power-down current consumption of 30 uA (compared with 240uA), maximum clock frequency of 24MHz (up from 18MHz), and a maximum speed of 40in/s at 6400 frames per second (compared with 14in/s at 1500frame/s).

IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
Both sensors offer a resolution of up to 800 counts per inch.
The ADNS-3060 is designed for use with the Agilent ADNS-2120/ADNS-2120-001 lens, the ADNS-2220/ADNS-2220-001 clip and the HLMP-ED80-XX000 LED.
Together these parts form a complete, compact mouse sensor solution.
The ADNS-3060 sensor uses a self-adjusting frame rate, which automatically matches the frame rate to the surface characteristics for optimum performance.
If the navigation surface reflects light efficiently, for example, the sensors will tune for a higher frame rate to improve the tracking performance; in previous optical sensors the frame rate was adjusted by external microcontroller firmware.
The self-adjusting frame rate feature can be disabled if manual control is preferred.
The ADNS-3060 contains an image acquisition system (IAS), a digital signal processor (DSP) and a four-wire serial port.
The IAS acquires microscopic surface images via the lens and illumination system.
These images are processed by the DSP to determine the direction and distance of motion.
The DSP generates the delta-x and delta-y relative displacement values, which are converted into SPI (system-packet interface) signals.
An external microcontroller reads the x and y information, then translates the data into PS2 or USB signals before sending them to the host PC or game console.
The Agilent ADNS-3060 optical navigation sensor is available now through Agilent's direct sales channels and worldwide distribution partners.
The ADNS-3060 is delivered in a 20-pin DIP (dual inline package). Request a free brochure from Avago Technologies ...
