摘要： Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for logo detection for indoor positioning for use in or with a mobile device. Briefly, in accordance with one implementation, a method may include extracting, at a mobile device, visual features from one or more images captured via a camera sensor of the mobile device; and estimating a location of the mobile device based, at least in part, on a match between extracted visual features and one or more brand-specific visual signatures associated with one or more points of interest of one or more known locations. In some instances, an estimated location of a mobile device may be refined based, at least in part, on at least one additional POI of one or more POIs of one or more known locations.

摘要： Disclosed is a torque-adjustable wrench for a narrow space. The present disclosure relates to the technical field of assembly tools. The wrench comprises an elongated upper cover plate and an elongated lower cover plate, the space between the upper cover plate and the lower cover plate forms a mounting space, one end of the mounting space is provided with a screw pre-tightening mechanism, and the other end of the mounting space is provided with an adjustable screw locking mechanism. During use of the wrench, first, the screw pre-tightening mechanism is used to pre-tighten a screw to be assembled, and then the adjustable screw locking mechanism is used to perform locking operation on the pre-tightened screw. By means of the wrench, the mounting and dismounting of a screw in a narrow space can be conveniently achieved.
