    • A cylindrical back washing purification apparatus comprises a main body (1), a cylindrical through hole (2) transversely provided in the main body (1), a plunger (4) slidably connected in the axial direction arranged in the through hole (2), a feed channel (6) and a discharge channel (8) connected with the through hole (2) on the main body (1). The outer peripheral portion of the foreside of the plunger (4) is concaved inward to form an annular cavity (10) with the inner wall of the through hole (2), the annular cavity (10) is connected with the feed channel (6), a "L"-type hole (12) which is connected with the discharge channel (8) is provided on the plunger (4) from fore to back in the axial direction, filtering holes (14) for connecting the annular cavity (10) with the "L"-type hole (12) are opened on the concaved peripheral face of the plunger (4) in the radial direction, a detachable filter screen (15) is coupled with the concaved peripheral face of the plunger (4). A strip (3) contacting with the inner wall of the through hole (2) is arranged in the annular cavity (10) on the plunger (4) in the axial direction; on the outer surface of the plunger (4), a semicircular groove (16) is provided on both sides of the discharge channel (8).

    • Technologies for determining a user's location include a mobile computing device(100) to determine, based on sensed inertial characteristics of the device, a walking gait of a user. The walking gait is one of a first gait indicative of the user holding the device to the user's side or a second gait indicative of the user swinging the device along the user's side. The device further detects that the user has taken a physical step based on the inertial characteristics and the determined walking gait of the user, and determines a raw directional heading of the device indicative of a direction of the physical step. The device determines an estimated location of the user based on the determined raw directional heading, an estimated step length, and the user's previous location.
    • 用于确定用户位置的技术包括移动计算设备(100),用于基于感测到的设备的惯性特性来确定用户的步行步态。 步行步态是指示用户将设备保持到用户侧的第一步态或指示用户沿用户侧摆动设备的第二步态之一。 该装置进一步检测用户已经基于惯性特性和所确定的用户行走步态进行了物理步骤,并且确定指示物理步骤的方向的设备的原始方向方位。 设备基于所确定的原始方向标题,估计的步长和用户的先前位置来确定用户的估计位置。
