摘要:
A memory voltage control circuit includes two slots, a control circuit, a voltage conversion circuit, and a switch circuit. The two slots are able to efficiently process different memory types. The control circuit receives memory identification signals from the two slots. The control circuit administers the output voltage of the voltage conversion circuit according to the memory identification signals. The memory identification signals determine whether the switch circuit is to be turned on or off. This will control whether the output voltage of the voltage conversion circuit will go to the first or the second slot.

Wireless personal area network (Zigbee, Bluetooth, UWB) and wireless identification technologies (Near Field Communication (NFC), Radio Frequency Identification (RFID)) are implemented in particular client server functions and communications. Connected with an Authentication Server, a wireless HUB authenticates user identification and provides the user with access to secure data communication with a wireless terminal such as a cellular phone or a PDA. A Location Server provides user locations via methods such as RSSI, TDOA, and GPS and sends location information to a Center Control Server and the Authentication Server. With location information, the Center Control Server initiates and optimizes secure information processes and coordinates the functions of servers and user terminals.

Disclosed herein are phosphor compositions comprising a BAM phosphor BaMgAl10O17:Eu2+ and at least one other hexaaluminate that may also be europium activated. The BAM may be mixed with any number of different kinds of heaxaaluminates having a similar crystal structure. The aluminum ratio may also be adjusted to alter the defect structure or to produce a second phase. Addition of another hexaaluminate to BAM enhances emission intensity and resistance to degradation, which is beneficial to applications such as plasma display panels.

An exemplary device for controlling rotation speed of a computer fan includes an identifying device and a control circuit. The identifying device is configured for identifying the type of the computer fan. The control circuit configured for controlling rotation speed of the computer fan includes an electric switch, an integrated circuit, a first output terminal, and a second output terminal. The electric switch has a first terminal coupled to the identifying device to receive an identifying signal, a second terminal coupled to a super I/O chip to receive a PWM signal. The integrated circuit is configured to convert the PWM signal to an analog voltage signal. The first output terminal is configured to output the PWM signal to a PWM control pin of a fan header. The second output terminal is configured to output the analog voltage signal to a power pin of the fan header.

An electrical connector (100) for permitting insertion of a full sized plug and preventing insertion of a smaller sized plug includes an insulative housing (1) defining a receiving cavity (110) through a mating face (11) thereof for receiving a mating connector and a plurality of terminals (2) received in the housing. Each terminal defines a fixing portion (20) retained in the housing, a contacting portion (21) being inclinedly bent at an angle and extending into the receiving cavity from one end of the fixing portion and a soldering portion (22) extending from the other end of the fixing portion. The fixing portion further defines a supporting portion (23) with two ends connecting with the fixing portion, the supporting portion faces to and supports the contacting portion to prevent the contacting portion from further excursion.

Optimized delivery of locally applicable Internet content to users. A cache of locally applicable Internet content is maintained in a local content server, based upon a monitoring of locations of users requesting Internet content. Requests for Internet content are received from user equipment through a wireless network base station, and served from the local content server, which is logically proximate to the wireless network base station. The caching of locally applicable Internet content may be maintained on a layered basis. Secure action request receipt and corresponding performance, and item condition alerts are also described.
