A communication management system has a server module and a signal routing gateway that is connected to a plurality of different cellular network operators. At the signal routing gateway a request is received. The request is addressed to a network-specific address assigned to the server module in accordance with an addressing scheme of a cellular network operator. In response to the request the network-specific address is replaced with an internal address assigned to the server module in accordance with an internal addressing scheme of the communication management system. A response to the request is obtained from the server module. The response is addressed from the internal address. The internal address is replaced with the network-specific address. The response is sent to the cellular network operator. In some embodiments, this process is repeated for multiple requests from the plurality of different cellular network operators.

A combustion-powered driving tool for driving nails or other fasteners in which the starting characteristics of a motor in the tool are improved by varying the amount of voltage applied to the motor when starting the motor and during normal operations so that the motor is driven to reach the rotational speed required in normal operations quickly. Therefore, the combustion-powered driving tool does not require the use of an expensive low-inertia motor, but can use a relatively inexpensive core-type motor or the like with inferior starting characteristics, while improving the work efficiency and user-friendliness of the combustion-powered driving tool.

The invention relates to the field of functional surface preparation technology, and particularly relates to a capillary forming method for a preparing super oleophobic surface. The capillary forming method is suitable for preparation of a polymer super oleophobic surface, particularly suitable for the preparation of the super oleophobic surface under a simple condition. A pre-prepared micro-nano structure surface is employed as a template by the method; the template is put on a smooth and flat substrate which is coated by a liquid state polymer film; the template is separated 5-50 [mu]m from the substrate after contact with the separate speed ranging from 0.1 [mu]m/s to 5 [mu]m/s; the liquid state polymer is aggregated in a gap between the micro-nano structure and the substrate under the action of a capillary force; and at the time, the liquid state polymer is cured, so that a preparation of a secondary groove structure. Equipment required by the method is simple, preparation of the super oleophobic surface can be realized under a simple condition, preparation cost is low, and batch preparation can be easily realized.

A hybrid three dimensional (3D) hydrogen evolution reaction (HER) catalyst that is formed from a porous Ni foam support, a NiSe₂ scaffold positioned on the support; and layered transition metal dichalcogenide (LTMDC) or first-row transition metal dichalcogenide particles positioned on the NiSe₂ scaffold. The catalyst provides a low onset potential, large cathode current density, small Tafel slopes, and large exchange current densities, similar in catalytic power to Pt HER catalysts.

A fragrance cartridge comprising a reservoir containing a fragrance material and provided with channels to permit ingress of carrier gas into the reservoir and egress of fragrance-containing carrier gas from the reservoir, the channels being defined by capillaries having internal diameter and length dimensions sufficient to act as closure means to prevent, or substantially prevent, leakage of fragrance from the reservoir into a head space external of the cartridge when carrier gas flow is interrupted. The cartridge can be used for example to enhance the sensorial perception of a viewer, listener or consumer of an audio and/or visual performance or presentation, by passing fragrance borne on the carrier into a head space local to the listener, viewer or consumer.

The present invention relates to a method for a content provider of renewing the watermarking of theatrical content and for updating consumer devices to detect said renewed watermark, wherein a watermark is embedded in said theatrical content using at least a first watermark noise pattern. Renewing is performed by said content provider distributing at least a second watermark noise pattern, which is used for embedding and detecting said watermark in said theatrical content, to said consumer devices using a broadcast encryption technology. The invention further relates to a content provider system adapted to be used for renewing the watermarking of theatrical content and for updating consumer devices to detect said renewed watermark.

Systems and methods achieving scalable and efficient connectivity in neural algorithms by re-calculating network connectivity in an event-driven way are disclosed. The disclosed solution eliminates the storing of a massive amount of data relating to connectivity used in traditional methods. In one embodiment, a deterministic LFSR is used to quickly, efficiently, and cheaply re-calculate these connections on the fly. An alternative embodiment caches some or all of the LFSR seed values in memory to avoid sequencing the LFSR through all states needed to compute targets for a particular active neuron. Additionally, connections may be calculated in a way that generates neural networks with connections that are uniformly or normally (Gaussian) distributed.

The disclosure relates to catalytically active carbocatalysts, e.g., a graphene oxide or graphite oxide catalyst suitable for use in a variety of high value chemical transformations.

The present invention relates to substantially free flowing powder products as well as preparation thereof. The powder product comprises coated carriers with excellent functional properties. The powder products can be produced in a simple and cost efficient way.

Composite concrete pavement includes the surface course of normal concrete and subbase and/or lower layer of concrete with coarse aggregate defined as enriched limestone waste of grading intermediate between the coarse and fine aggregates. Specified compressive strength and modulus of rupture of this concrete amount up to 5,000 and 750 psi, respectively. Coarse aggregate of this concrete is enriched by-product of manufacture of crushed limestone of regular sizes. As a raw material for enrichment it should be coarser than 9.5 mm and finer than 4.75 mm. The amount of aggregate finer than 4.75 mm as a part of the total weight of aggregate should be not less than 1/3 before enrichment and close to but not exceed 2/3 in aggregate bin. The use of this very cheap and efficient concrete for composite concrete pavement allows reduction of initial cost of construction of this pavement and makes it more competitive as compared with asphalt pavement.
