Systems and methods are described for forming continuous curved laser filaments in transparent materials. The filaments are preferably curved and C-shaped. Filaments may employ other curved profiles (shapes). A burst of ultrafast laser pulses is focused such that a beam waist is formed external to the material being processed without forming an external plasma channel, while a sufficient energy density is formed within an extended region within the material to support the formation of a continuous filament, without causing optical breakdown within the material. Filaments formed according to this method may exhibit lengths in the range of 100 μm-10 mm. An aberrated optical focusing element is employed to produce an external beam waist while producing distributed focusing of the incident beam within the material. Optical monitoring of the filaments may be employed to provide feedback to facilitate active control of the process.

Protected publication of sensitive documents with authentication and accountability enables storing and sharing confidential files, while reducing risk that a recipient will distribute and share the file information with unauthorized recipients. Every user request for an original file generates a unique provided file based on the original file, the user request, and configuration information. The provided file has characteristics that make the provided file based on a first user request unique from any other provided file based on any other user request. Unique characteristics include changing the format of the original file to another format for the provided file, altering file properties, altering file content, and watermarking.

The invention discloses an elliptical vibration cutting auxiliary device based on three piezoelectric drives. The device includes a support mechanism, a compliant guide mechanism and a drive mechanism. The compliant guide mechanism and the drive mechanism are fixed on the support mechanism. The drive mechanism uses The point contact mode drives the compliant guiding mechanism, and the driving mechanism drives the compliant guiding mechanism to perform reciprocating motion in the x direction and to perform elliptical trajectory motion on the yz plane. The technical scheme of the present invention adopts the compound double parallel four-bar mechanism mode in the horizontal direction, which not only greatly increases the displacement in the horizontal direction, but also greatly reduces the stress on the flexible hinge moving in the horizontal direction, and improves the mechanical stability of the mechanism. Service life; the technical solution of the present invention adopts a combined flexible hinge with two ends connected in series in the middle of the yz plane and two parallel piezoelectric joints to realize high-frequency movement under low-coupling operation; this solution adopts the integration of compliant guide units , reducing the error of traditional assembly.

The invention discloses a set top box, an internet television and a method for processing intelligent control signals. The method comprises the steps that signals comprising language signals and / or action signals are received; data conversion is conducted on the signals, so as to obtain conversion codes of the signals; and control instructions corresponding to the signals are obtained according to the conversion codes, and corresponding television function interfaces are called according to the control instructions. Through adopting the set top box, the internet television and the method, people can convenient interact with the internet television by aiming at natural language, an action control method and a matching mechanism of the internet television, so that the practicality and the convenience of the operation of the internet television are improved, thereby improving the user experience.
