Lex helps write programs whose control flow is directed by instances of regular
expressions in the input stream. It is well suited for editor-script type transformations
and for segmenting input in preparation for a parsing routine.
Java is the first language to provide a cross-platform I/O library that is powerful enough to handle all these diverse tasks. Java is the first programming language with a modern, object-oriented approach to input and output. Java s I/O model is more powerful and more suited to real-world tasks than any other major language used today. Java I/O is the first and still the only book to fully expose the power and sophistication of this library.
Emdros is a text database middleware-layer aimed at storage and
retrieval of "text plus information about that text." This
information could be linguistic analyses or other annotations. Emdros
provides an abstraction of text that makes it well suited to storing
/syntactic analyses/ of text, but other linguistic information is
supported as well. Emdros comes with a query-language, MQL, that
enables powerful queries. Emdros acts as a middleware-layer between a
client (not provided) and a database back-end. Currently, PostgreSQL,
MySQL, and SQLite (2 and 3) are supported, but other back-ends can
easily be added.
The new digital radio system DAB (Digital Audio Broadcasting, nowadays often called
Digital Radio) is a very innovative and universal multimedia broadcast system which will
replace the existing AM and FM audio broadcast services in many parts of the world in
the future. It was developed in the 1990s by the Eureka 147/DAB project. DAB is very
well suited for mobile reception and provides very high robustness against multipath
reception. It allows use of single frequency networks (SFNs) for high frequency
efficiency.
Recent advancements in nanotechnology (NT) materials and growth of micro/
nanotechnology have opened the door for potential applications of microelectro-
mechanical systems (MEMS)- and NT-based sensors and devices. Such sensors and
devices are best suited for communications, medical diagnosis, commercial, military,
aerospace, and satellite applications. This book comes at a time when the future and
well-being of Western industrial nations in the twenty-first century’s global eco-
nomy increasingly depend on the quality and depth of the technological innovations
they can commercialize at a rapid pace.
The PW5410B is a low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. Itproduces a regulated output voltage from 1.8V to 5V input with up to 100mA of output current. Lowexternal parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) makethe PW5410B ideally suited for small, battery-powered applications
The PW5410A is a low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. Itproduces a regulated output voltage from 2.7V to 5V input with up to 250mA of output current. Lowexternal parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) makethe PW5410A ideally suited for small, battery-powered applications
The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2μA. The PW4055 can be put into shutdown mode, reducing the supply current to 25μA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage
The PW2053 is a high-efficiency monolithic synchronous buck regulator using a constantfrequency, current mode architecture. The device is available in an adjustable version. Supply currentwith no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makesthe PW2053 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provideslow dropout operation, extending battery life in portable systems. PWM/PFM mode operationprovides very low output ripple voltage for noise sensitive applications. Switching frequency isinternally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Lowoutput voltages are easily supported with the 0.6V feedback reference voltage
