Storage device and method for providing a partially-encrypted content file to a host device
A storage device and method for providing a partially-encrypted content file to a host device are provided. In one embodiment, the storage device retrieves a content file from memory in the storage device and partially-encrypts the content file by encrypting some portions of the content file. The storage device sends the partially-encrypted content file to a host device and informs the host device of which portions of the partially-encrypted content file are encrypted. In one embodiment, the remaining portions of the content file are in clear text form and do not need to be decrypted.

Apparatus and methods of displaying messages for electronic devices
An apparatus of transmitting messages from an electronic device and display it on a mobile device, and a method of doing the same are disclosed. An exemplifying electronic device has an encoder to encode the data and a drive to modulate the signals into temporal and spatial light patterns according to the transmitted message. The light signals are then emitted from a group of LEDs on the electronic device. A video camera on a mobile device captures the light signals in the form of temporal and spatial patterns. A software application decodes the message and displays the message on the mobile device screen. |

Photonic circuit
An integrated or monolithic photonic circuit that modulates RF signals onto optical signals and then performs a channelizing filter function according to the RF content. According to an exemplary embodiment, the photonic circuit is employed in an aircraft system that includes a front end, a photonic circuit, an optical connection, and an electronic module at some distant location in the aircraft. RF signals are received by an antenna in the front end, the RF signals are then modulated onto optical signals by a modulator and a laser, the modulated optical signals are filtered by a filter array according to a channelizing filter function, and the modulated and channelized optical signals are then carried over the optical connection to the electronic module. Other options like a wavelength-tunable laser and corresponding feedback feature, as well as ring filters with integrated semiconductor optical amplifiers (SOAs) are also possible. |
