Output devices supporting wireless device discovery are herein disclosed and enabled. To setup an output device for wireless connection, wireless device discovery is performed by a client of the output device to discover the output device. Upon being discovered, the output device may provide identification or information related to the output device to the client for establishing a wireless connection. Subsequently, the output device may receive, via the established wireless connection, digital content from the client for output. Wireless device discovery operations may be based on one or more of a close proximity wireless communication, a Bluetooth wireless communication, or a wireless communication compatible with a protocol within IEEE 802.11 standards. Security information or authentication may be required for establishing the wireless connection. Subsequent to having established the wireless connection, the output device receives the audio or video content from the client for playing at the output device.

A wireless device that includes at least a wireless communication unit, which is compatible with at least a protocol within IEEE 802.11 standards, for establishing a wireless connection with a server over a network is herein disclosed and enabled. To connect the wireless device with the server, the wireless device may first establish short range wireless communication with a client device, such as a smart phone. The wireless device may exchange data or information with the client device via the short range wireless communication; and the wireless device may implement an authentication procedure for detecting authentication information. Thereafter, the wireless device connects to the server over the Internet for accessing a service provided by the server. The accessing of the service may require authentication information on the wireless device, and the accessing of the service is subsequent to the wireless device having implemented the authentication procedure at the wireless device.

A system and method for network policy enforcement for portable data devices such as smartphones, tablets or notebook computers uses the portable device to self-enforce prescribed policies. A beacon generator generates a wireless security beacon in accordance with an output of the beacon generator and a wireless data interface receives an access request from a portable data device. Digital security policy data configured to enable a preselected set of functions on the portable data device is stored in the data storage. The processor communicates the policy data to the portable data device in accordance with a received access request via the wireless data interface.

Output systems (e.g., information apparatus, Internet appliances, information pads, smart phones, audio output devices) supporting voice commands for playing digital content received from a service provided over a network (e.g., Internet) are herein disclosed and enabled. The output system may include an interface (e.g., touch sensitive screen interface, wireless interface) for receiving authentication information to access the service over the network. The service may be a subscribed service. While connected to the service, the output system receives voice commands from a user for outputting or playing digital content, and, in response to the voice commands, the output system receives, from the service, output data related to the digital content for outputting or playing at the output system. The output system may include a digital camera for image acquisition and may further be Bluetooth enabled for wirelessly receiving audio data (e.g., music) from a mobile device.

A method and apparatus for generating image information. A specific embodiment of the method includes: acquiring a rotation angle and a scaling of a target image relative to a reference image, and acquiring an intrinsic parameter of a video camera collecting the reference image; generating a projective transformation matrix based on the rotation angle, the scaling and the intrinsic parameter; generating a coordinate offset of the each neighborhood pixel of the feature point in the reference image; generating, based on a coordinate of the feature point in the reference image, the coordinate offset of the each neighborhood pixel of the feature point in the reference image and the projective transformation matrix, coordinates of the each neighborhood pixel of the feature point in the reference image; and generating a feature point descriptor of the feature point.

Output devices supporting wireless device discovery are herein disclosed and enabled. To setup an output device for wireless connection, wireless device discovery is performed by a client of the output device to discover the output device. Upon being discovered, the output device may provide identification or information related to the output device to the client for establishing a wireless connection. Subsequently, the output device may receive, via the established wireless connection, digital content from the client for output. Wireless device discovery operations may be based on one or more of a close proximity wireless communication, a Bluetooth wireless communication, or a wireless communication compatible with a protocol within IEEE 802.11 standards. Security information, such as a password, biometrics, or a PIN, may be required for establishing the wireless connection. The output device may automatically obtain the security information from the client or may be based, in part, on user input.

An electronic device includes an amplifier, a signal conversion unit configured to include at least one photodiode, in response to an optical signal being received from an external device, convert the received optical signal into an electric signal by using the at least one photodiode and output the electric signal, and a processor configured to control to supply power to the amplifier in response to the electric signal being received from the signal conversion unit, wherein the amplifier, in response to the power being supplied, receives the electric signal from the signal conversion unit, amplifies the received electric signal and outputs the amplified electric signal to the processor.

A data communication method enabling wireless sharing of files or data between electronic devices that can store information and/or generate information by means of touch surface (capacitive or multi-touch), display units (LCD, led, etc.), photo sensor and frame having negative electrical conductivity.

Output systems (e.g., information apparatus, Internet appliances, audio devices or video output devices) supporting voice commands for playing digital content received from a service provided over a network (e.g., Internet) are herein disclosed and enabled. The output system includes a touch sensitive screen interface for receiving security information to access a wireless local area network and for receiving authentication information to access the service over the network. The service may be a paid or subscribed service. While connected to the service, the output system receives voice commands from the user for outputting or playing selected digital content, and, in response to the voice commands, the output system receives, from the service, output data related to the selected digital content for outputting or playing at the output system. The output system may include a digital camera for image data acquisition or video data acquisition and may further be Bluetooth enabled.

Wireless printing devices that are configured to register with a service over a network (e.g., Internet) for providing printing services for one or more client devices without printer drivers are herein disclosed and enabled. The printing device may include a touch sensitive screen interface to receive security information for connecting to a wireless local area network (LAN). While connected to the wireless LAN, the printing device accesses the service for registering the printing device, and transmits device information related the printing device to the service. Subsequent to registration, one or more client devices using the service over the network may select the registered printing device for printing, and the printing device is configured to receive output data either from the service or via a computing device within the wireless LAN, and wherein output data is related to the device information transmitted to the service.
