  • Patent number: 11758366
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a computer-implemented method for displaying a heat map are provided. One of the methods includes: receiving heat data from a server, wherein the heat data comprises a color value associated with each of a plurality of regions and one or more geographic locations respectively corresponding to one or more boundary points of each of one or more heat regions among the plurality of regions; generating a first heat map comprising a plurality of pixels; obtaining a second heat map by adjusting the color value of each pixel in the first heat map; and providing the second heat map for display, wherein the second heat is superimposed on a digital map. This method addresses the issue of conventional techniques that service request information may be misrepresented due to abrupt changes in color values across neighboring heat regions.

  • Patent number: 9534975
    Abstract: A pressure sensor assembly for measuring the pressure of a first fluid. The assembly having a first housing including a pressure sensing device arranged therein. A diaphragm is arranged on a surface of the first housing and is configured to transmit a force exerted on a first side thereof to the pressure sensing device. A second housing is provided and attached to the first housing. The second housing may be arranged generally circumferentially around the diaphragm. A compressible element is provided and arranged within a compressible element space defined within the second housing. The compressible element is configured to transmit a force exerted thereon by the fluid to the first side of the diaphragm.
