Abstract: The present invention relates to a mining hose connecting device and method, and belongs to the field of underground hydraulic equipment for coal mines. The mining hose connecting device comprises a joint unit, wherein the joint unit comprises a first joint and a second joint; a first fastening unit, wherein the first fastening unit is arranged symmetrically about a first plane, and the inner diameter of the first fastening unit is respectively in clearance fit with the outer diameters of the first joint and the second joint; and a second fastening unit, comprising a first fastener and a second fastener, wherein the inner diameters of the first fastener and the second fastener are respectively in clearance fit with the outer diameter of the first fastening unit.

Abstract: The application discloses an NFC antenna for handheld devices and a handheld device. The NFC antenna includes an antenna base and a coupling coil arranged along the edge of the antenna base. The antenna base integrally includes a first antenna base and two second antenna bases. The first antenna base is arranged on a backside of the handheld device, with two sides bending and extending towards the frontside of the handheld device to form the second antenna bases. The second antenna bases are respectively located on sides of the handheld device and outside the screen assembly of the handheld device. The NFC antenna covers the sides of the handheld device, so that NFC antenna signals at the sides can be sensed at the frontside, thereby NFC cards can be swiped at both the frontside and backside of the handheld device, without occupying space at the frontside.

Abstract: Methods and embodiments of a high-performance parallel multi-literal matching algorithm called NeoHarry. A chunk of data comprising a character string comprising n bytes is sampled for a byte stream, and data in the sampled chunk are pre-shifted to create shifted copies of data at multiple sampled locations. A mask table is generated having column vectors containing match indicia identifying potential character matches. A look up of the mask table at multiple sampled locations using the pre-shifted data is performed for a target literal character pattern. The mask table lookup results are combined to generate match candidates and exact match verification is performed to identify any generated match candidates that match the target literal character pattern. NeoHarry uses a column-vector-based shift-or model and implements a cross-domain shift algorithm under which character patterns spanning two domains are identified.

Abstract: A microphone structure for a mobile phone is provided on the body (210) of the mobile phone. The microphone structure comprises a microphone module (220) connected to a main board circuit of the mobile phone. On the body (210) of the mobile phone, a microphone hole (212) is formed at the middle part of a case (211) faced to a user. The microphone module (220) is installed toward the microphone hole (212). For the microphone being formed at the middle part of the mobile phone, the microphone structure for a mobile phone in the present invention reduces the influence between a lower antenna and the microphone, and the voice quality influence caused by the wrong operation of a user, and it is convenient for a user to use.
