Contacts The Windows Phone 7 contact list (People Hub) is the center of user communication. The mobile phone user can view the social networking update contents and photos of the Windows Phone 7 application list friend in the contact menu. Here also provides users with Facebook and Windows Live personal page update capabilities.
Albums Windows Phone 7's Photos Hub enables the perfect support for local storage of photos and online photo albums stored locally on the mobile phone. Users can also use this feature to update their social networking home photos.
Office Center Windows Phone 7 provides quick access to locally installed Office Mobile, Office SharePoint, and Office OneNote. Microsoft Office Outlook email service is also provided.
The game station Windows Phone 7 game station (Games Hub) provides users with the latest Xbox LIVE gaming experience. The company once again emphasizes the concept of game socialization.
Music and Video Music + Video Hub for Windows Phone 7 is the media player for mobile phones, with local music, streaming media, broadcasts, and video.
Dimmable LED Ligh shoebox can be adjusted the brightness of the light, including 0-10v dimmable,Dali dimmable, Triac dimmable and Zigbee dimmable.
0-10V Dimmable:
Used as an early fluorescent dimming system and still used today, 0-10V dimming has been adapted to become a reliable LED dimming control protocol.0-10 V is one of the earliest and simplest electronic lighting control signaling systems; simply put, the control signal is a DC voltage that varies between zero and ten volts. The controlled lighting should scale its output so that at 10 V, the controlled light should be at 100% of its potential output, and at 0 V it should at the lowest possible dimming level.
Dali dimmable:
A basic system could consist of a few light fittings and a switch connected to a DALI group controller. The switch provides on/off control and up/down dimming of the fittings. Minimal configuration is required and ballasts do not need to be individually addressed.A grouped system consists of multiple ballasts individually addressed on a DALI Line Inputs on a Line Controller or a group controller can be configured to provide switching and dimming as required.
SCR Dimmable:
A SCR is a four-layer solid state device that controls current. In the normal [off" state, SCR restricts current to the leakage current. When the gate-to-cathode voltage exceeds a certain threshold, SCR turns [on" and conducts current. A SCR will remain in the [on" state even after gate current is removed so long as current through the device remains above the holding current. Once current falls below the holding current for an appropriate period of time, the device will switch [off". If the gate is pulsed and the current through SCR is below the holding current, SCR will remain in the [off" state.To achieve the dimming effect using SCR dimming technique, first, a RC phase shift is used to delay triggering the gate-to-cathode voltage. There will be a phase-cutting and the Root Mean Squared Voltage VRMS is modified. The symmetric characteristic of DIAC (DIode for Alternating Current) can be used to trigger TRIAC (TRIode for Alternating Current) symmetrically. Then, the dimming effect can be achieved by varying the R1 value that changes the phase angle for conduction.
Zigbee:
Zigbee is a kind of brand-new, focus on low power consumption, low cost, low complexity and low rate of short-range wireless communication technology.Is also a big focus in the embedded application.
