The present invention relates to a method for preparing a natural or synthetic polymer hydrogel loading graphene oxide or graphene, and to the selective and high-capacity adsorption and loading of the hydrogel with respect to a low-molecular weight material or a high-molecular weight material. More specifically, an alginate or polyacrylamide hydrogel loading graphene and a graphene derivative is prepared, wherein the hydrogel can be controlled to enable selective absorption according to the characteristics of an adsorbate by adjusting the reduction degree of graphene oxide, exhibits high adsorption capacity, and is easy to handle as a hydrate. These characteristics can significantly improve the adsorption efficiency with respect to a material in water or an organic phase material, compared with existing hydrogels.

The invention relates to a temperature control system and a method thereof. In the system, a temperature signal sensed by a temperature sensing module is filtered, amplified and converted into temperature data through a signal acquisition module, and is sent into a PLC; the PLC is communicated with a control module through network to transmit the temperature data; the control module compensates the temperature data of each sampling channel to acquire the actual temperature value of each temperature sensing point, combines with temperature to control target track data and the actual temperature value, and generates a control command by combining a set control mode and a control parameter; after the control command is sent to the PLC through data flow from the top to the bottom, the control command is converted into a signal which can be received by a control signal output module by the PLC; and the control signal output module drives a transformer to output corresponding heating power. The system and the method have the advantages of strong pertinence, high control accuracy and wide application range.

A gas blower device for blowing gas onto a face of a traveling strip of material. The device has at least one hollow box fitted with a plurality of tubular nozzles pointing towards the face in question of the strip of material. On the side facing towards the face in question of the strip of material, the hollow box presents a surface of profile (P) that varies in at least one given direction (D) symmetrically about a midplane (Q) perpendicular to the plane of the strip. The tubular nozzles are fastened via their roots to the varying-profile surface in such a manner that their respective axes are essentially orthogonal to said varying profile at the point in question, said tubular nozzles having respective lengths that are selected so that the outlet orifices lie in a common plane substantially parallel to the plane of the strip.

The supporting equipment for the petroleum transmission pipeline realizes the technical effects of lower cost, convenience in detaching and capability of repeated use.

A non-computer interface to a storage system includes a set top box (STB) or interface unit connected to a storage system for storing information to be accessed by a user. The storage system can be a database, such as a relational database having a plurality of tables, or a digital library system, for storing information to be accessed by the user. Also stored in the storage system are navigation information or rules for controlling a user's navigation of the database. A user interacts with the storage system through the STB, sending navigation commands to the storage system via the STB. The navigation commands available to a user are generated by combining the navigation rules with the user's access privileges. The user can send navigation commands via a remote controller which sends cursor control commands to the STB. Alternatively, the user can send navigation commands via a virtual reality interface.

The present invention relates to a system for position detection, implementing RF-based distance measurement, the system comprising at least one transmitting unit (12) arranged for transmitting an electromagnetic wave signal in the RF range, at least one receiving unit (14) arranged for receiving an electromagnetic wave signal in the RF range, wherein the transmitting unit (12) is arranged to transmit an electromagnetic wave signal specifically formed for distance measurement, and wherein the receiving unit (14) is arranged to receive the electromagnetic wave signal transmitted by the transmitting unit (12) in a direct or mediate fashion, at least one control device (30) for distance measurement based on transmitted signal information and received signal information, the control device (30) further comprising a distance measurement quality assessment unit (32), and a power consumption optimizing unit (34), wherein the distance measurement quality assessment unit (32) is arranged to derive a distance measurement quality indicator, based on distance measurement results, and wherein the power consumption optimizing unit (34) is arranged to adapt at least one transmitting parameter, based on the quality indicator.

A low cost design for a concentrated photovoltaic (CPV) solar cell device is developed with a 3-D solar cell structure that eliminates the need for sun-ray tracking and with improved electricity conversion efficiency for cooling solar cells. The 3-D solar cell structure can be built with conventional monocrystalline or polycrystalline silicon or with multi-junction III-V solar material, joining two or more solar cell segments perpendicular to a base solar cell. This structure is able to collect all incident sunlight from sunrise to sunset.

A composition for nasal or buccal application comprising a distribution of multilayer microparticles in an inactive base, at least one ingredient having activity on the mucosa of the nose/throat, being adsorbed within the layers of the microparticles so as to be progressively released over time in use.

A movable aerodynamic surface for an aircraft is disclosed including a skin having a first skin portion and a second skin portion both extending from the leading edge to the trailing edge and together surrounding an interior from opposite sides, and a stiffener arrangement arranged in the interior and including at least an inboard stiffener in the area of the inboard end and/or an outboard stiffener in the area of the outboard end. At the inboard end between the first skin portion, the second skin portion and the inboard stiffener an inboard cavity is formed, and/or at the outboard end between the first skin portion, the second skin portion and the outboard stiffener an outboard cavity is formed. An acoustic filler arrangement including multiple filler elements is arranged within the inboard cavity and/or the outboard cavity for reducing noise.

A method of determining whether an improved item has a better mean lifetime than an existing item having a fully specified lifetime distribution function. A finite number n of examples of the new item are placed on life test, and the failure times of the n examples of the new item are recorded as they occur. At each occurrence of failure, the newly noted failure time is entered into a list of previously noted failure times and the most up-to-date statistical P-value is calculated for the life test so far. When the statistical P-value is sufficiently small there is statistical inference that the new item is better than the current one, and the test is ended.
