Abstract: The present disclosure provides an earphone comprising a sound production component and an ear hook. In a wearing state, the ear hook is configured to place the sound production component at a position near an ear canal but not blocking the ear canal. An inner contour of the ear hook's projection on a user's sagittal plane includes a first curve having an extremum point in a first direction. The first direction is perpendicular to a long-axis direction of a projection of the sound production component on the sagittal plane. The extremum point is located behind a projection point of an upper vertex of the ear hook on the sagittal plane, and the upper vertex is a highest point of an inner contour of the ear hook along the user's vertical axis. An inclination angle of the long-axis direction relative to a horizontal direction is within a range of 13°-21°.

Abstract: The present invention belongs to the field of environment monitoring, particularly relates to a CO2 storage state networking monitoring device, system and method with multi-information fusion. The present invention comprises: obtaining orientation electrical signal data and real-time pressure signals, analyzing a fluid flowing state at a view of a pressure sensor through the real-time pressure signals, and obtaining a CO2 flowing state through the orientation electrical signal data; and obtaining a CO2 regional storage state by combining an orientation CO2 content, a CO2 flowing state and the fluid flowing condition at the view of the pressure sensor. By combining accurate short-range CO2 boundary monitoring of orientation electrodes with long-range monitoring of pressure sensors to achieve a wide range of CO2 flowing state monitoring, the present invention can observe more data with higher reliability and effectively aims at the problem of strong inter-well heterogeneity.

Abstract: A terminal device may comprise a non-transitory processor-readable medium and a processor in communication with the storage medium. The storage medium may include a set of instructions for displaying a perspective view map to a user. The processor may be configured to execute the set of instructions to obtain a target image showing a vicinity of a target location in a perspective view along a target direction; determine a plurality of target objects that locate in the vicinity of the target location along the target direction; generate an overlaid target image by overlaying target information associated with the target objects on the target image; and display the target image overlaid with the target information.

Abstract: A monolithic fuel cell is described which is made up of fuel passages and oxidizer passages, in the form of a monolithic block. The monolith is made from triplex layers of anode-electrolyte-cathode and a multifunctional substrate that provides interconnects between triplex layers, provides for gas diffusion and allows waste products to flow out through it to be extracted. Additionally, it provides current take-off where desired. The monolith may be a cube, a rectangular prism or a solid cylinder, made of layers of different materials with different design patterns. Also detailed is a low cost, high-speed fabrication method for manufacture of a monolithic block of fuel cells, using computer-aided design/computer-aided manufacturing to send instructions to a process management controller. The controller selects materials and defines their preparation and then sends these materials to robotic fabrication stations, which are also programmed by the controller.
