  • Patent number: 10347996
    Abstract: An electrical connector includes a barrel type terminal, having a first connecting area and a second connecting area. The first connecting area has a first non-soldering surface and a first soldering surface. The second connecting area has a second non-soldering surface and a second soldering surface. Each of the first and second soldering surfaces and the first and second non-soldering surfaces has a first solder layer. A sleeve sheathes outside the barrel type terminal, and has a first fixing area and a second fixing area. Two second solder layers are provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface. The amount of solder provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface is greater than that provided on the first and second non-soldering surfaces.

  • Patent number: 10320130
    Abstract: A barrel terminal has one end for inserting a mating member and the other end for connecting a cable. The barrel terminal includes a contact portion, a connecting portion, and a buffer portion connecting the contact portion and the connecting portion. The contact portion has multiple contact elastic pieces, and the contact elastic pieces are used for electrically contacting the mating member. The connecting portion is used for connecting the cable. The buffer portion has multiple absorption portions. The absorption portions absorb the deformation stress of the connecting portion to prevent the stress from being transferred to the contact portion, to avoid the deformation of the contact elastic pieces, so as not to cause the reduction of the contact area between the contact elastic pieces and the abutment terminal, and to prevent reduction of a clamping force of the barrel terminal to the mating member.

  • Publication number: 20190126071
    Abstract: A method and system for using in a two-modality apparatus. The two-modality apparatus comprises a couch with a table top, a first modality unit and a second modality unit. A second image of a target portion of an object when the table top is at a second working position of the second modality unit may be acquired. A second sag of the table top at a second measurement point of the table top according to the second image may be determined based on the image. A difference between a first sag of the table top at a first measurement point of the table top and the second sag may be estimated based on the second sag and standard data. The standard data provides a relationship relating to a sag of the table top positioned between the first modality unit and second modality unit.

  • Publication number: 20190067504
    Abstract: Luminescent solar concentrators in accordance with various embodiments of the invention can be designed to minimize photon thermalization losses and incomplete light trapping using various components and techniques. Cadmium selenide core, cadmium sulfide shell (CdSe/CdS) quantum dot (“QD”) technology can be implemented in such devices to allow for near-unity QDs and sufficiently large Stokes shifts. Many embodiments of the invention include a luminescent solar concentrator that incorporates CdSe/CdS quantum dot luminophores. In further embodiments, anisotropic luminophore emission can be implemented through metasurface/plasmonic antenna coupling. In several embodiments, red-shifted luminophores are implemented. Additionally, top and bottom spectrally-selective filters, such as but not limited to selectively-reflective metasurface mirrors and polymeric stack filters, can be implemented to enhance the photon collection efficiency.

  • Patent number: 10073293
    Abstract: An optical microcavity for a high-contrast display comprises an enclosed cavity having a front wall and a back wall, where the front wall comprises a pinhole opening for emission of light from the cavity and the back wall is configured to generate or transmit light into the cavity. An outer surface of the front wall absorbs some or substantially all optical wavelengths of externally incident light so as to appear black or colored. An inner surface of the front wall comprises a light reflectivity of greater than 90% to promote photon recycling within the cavity and light emission through the pinhole opening.

  • Patent number: 9636027
    Abstract: A method of detecting changes in biologically sourced electrical signals is disclosed. Biologically sourced electrical signals are coupled to a meta-stable and hair-trigger wise perturbable system. The system operates in a first oscillatory mode when the received signals have a strength below a first predetermined level and operates in a distinguishable second oscillatory mode when the received signals have strengths above the first predetermined level but below a second predetermined level. The strengths of the received and thusly distinguishable signals may be in a range below 10 picoAmperes. The biologically sourced electrical signals may be driven by intracranial nerve firings.

  • Patent number: 9609791
    Abstract: A method for deploying a lightweight, flexible Faraday cage around a device can include the step of directing the conductive fluid flow in a manner that causes a shroud to form over the device. In some embodiments, a flexible material such as canvas can be deployed over the device and the conductive fluid can be sprayed onto the flexible material to form the shroud. In other embodiments, a plurality of nozzles can be placed around the perimeter of the device, and the nozzles can be directed at a predetermined point over the device. The streams can meet at the predetermined point, collide and thereby provide the conductive shroud for the device. The shroud can have a skin depth, which can be chosen according to the desired frequency of electromagnetic radiation to be blocked, typically from one to one hundred millimeters (1-100 mm).

  • Publication number: 20160245938
    Abstract: A frequency increasing processing method of a digital signal includes the following steps: S101, inputting a real signal trace collected in a certain period of time; S102, performing Hilbert transform on the real signal trace so as to obtain an instantaneous amplitude trace of the real signal trace; S103, based on the instantaneous amplitude trace, performing frequency increasing and polarity transform processing on the real signal trace so as to obtain a frequency increasing signal trace. Thus, a weak signal source can be identified without a large number of strong events. This shows advantages of environmental protection and cost reduction in the field of shale gas hydraulic fracturing micro-seismic monitoring. In addition, the zero polarity transform and frequency increasing processing in the present invention are simple in steps and are highly universal.
