Abstract: Mechanical misalignment and scaling factors lead to a mismatch between the values coming from a touchscreen panel (as translated by a touch screen controller) and the display (typically an LCD) on which the touch screenpanel is mounted. This tutorial discusses how to calibrate the touch screen panel to match the display.
Advances in low power electronics now allow placementof battery-powered sensors and other devices in locationsfar from the power grid. Ideally, for true grid independence,the batteries should not need replacement, but instead berecharged using locally available renewable energy, suchas solar power. This Design Note shows how to producea compact battery charger that operates from a small2-cell solar panel. A unique feature of this design is thatthe DC/DC converter uses power point control to extractmaximum power from the solar panel.
According to CIBC World Markets, Equity Research, theFlat Panel Display (FPD) industry has achieved sufficientcritical mass for its growth to explode. Thus, it can nowattract the right blend of capital investments and R&Dresources to drive technical innovation toward continuousimprovement in view quality, manufacturing efficiency,and system integration. These in turn are sustainingconsumer interest, penetration, revenue growth, and thepotential for increasing long-term profitability for industryparticipants. CIBC believes that three essential conditionsare now converging to drive the market forward
In today’s world of modular networking and telecommunications design, it is becomingincreasingly difficult to keep alignment with the many different and often changing interfaces,both inter-board and intra-board. Each manufacturer has their own spin on the way in whichdevices are connected. To satisfy the needs of our customers, we must be able to support alltheir interface requirements. For us to be able to make products for many customers, we mustadopt a modular approach to the design. This modularity is the one issue that drives the majorproblem of shifting our bits from one modular interface to another.
