Abstract: An electronic device includes a first set of sensors configured to generate motion information. The electronic device also includes a second set of sensors configured to receive information from multiple anchors. The electronic device further includes a processor configured to generate a path to drive the electronic device within an area. The processor is configured to receive the motion information. The processor is configured to generate ranging information based on the information that is received. While the electronic device is driven along the path, the processor is configured to identify a location and heading direction within the area of the electronic device based on the motion information. The processor is configured to modify the estimate of location and the heading direction of the electronic device based on the ranging information. The processor is configured to drive within the area according to the path, based on the location and heading direction.

Abstract: A superficial flow sensor is provided, which may comprise a substrate, and a thin film comprising a self-rolled portion, a stationary portion, and a free ribbon portion. According to some aspects of the present disclosure, the self-rolled portion may be configured to have a residual stress and to deform under external forces.

Abstract: A superficial flow sensor may include a substrate; a thin film with a self-rolled portion, a stationary portion, and a free ribbon portion; an embedded strain gauge circuit; and at least one contact pad. According to some aspects, the self-rolled portion may deform under external forces, and the embedded strain gauge circuit may detect the deformation of the self-rolled portion.

Abstract: A direct-insertion baluster connecting device, including a fence frame and a plurality of balusters uniformly arranged within the fence frame. The fence frame is a square frame jointly consisting of two vertical posts, an upper rail and a lower rail. The fence frame and the balusters are hollow tubes and a plurality of rivet nuts are arranged about the lower end of each vertical post. The disclosed direct-insertion baluster connecting device can be used for the installed fence frame formed by the vertical posts, upper rail and lower rail, and then it only needs to directly insert the balusters and make connection in a specified manner.

Abstract: A gas flow sensing device, and related method of manufacturing, comprising a conductive layer encapsulated in dielectric film, suspended over a cavity to form a diaphragm. The conductive layer functions as both a heating a sensing element and is patterned to provide uniform heat distribution across the diaphragm. The device is designed to sense flow from any direction relative to the device and the design of the dielectric film and diaphragm reduces sensor drift during prolonged operation.

Abstract: The present invention discloses a direct-insertion baluster connecting device, including a fence frame and a plurality of balusters uniformly arranged within the fence frame; the fence frame is a square frame jointly consisting of two vertical posts, an upper rail and a lower rail; the fence frame and the balusters are all hollow tubes; and a plurality of rivet nuts are arranged about the lower end of each vertical post. The disclosed direct-insertion baluster connecting device can be used for the installed fence frame formed by the vertical posts, upper rail and lower rail, and then it only needs to directly insert the balusters and make connection in a specified manner. The whole connecting process is a welding-free process, and only needs manual assembly in a DIY manner, thus ensuring beauty and safety, as well as convenient and labor-saving assembly, and it can be accomplished without too much auxiliary work.

Abstract: A gate bracket is formed of a planar web in which two rectangular portions along two edges of the web are bent to define a first pair of perpendicular flanges, and two other rectangular portions are bent from an inner portion of the web to form a second pair of perpendicular flanges. The flanges of the first pair are spaced from the flanges of the second pair by a distance corresponding to the dimensions of the structural members used to construct the gate. The invention provides a rigid bracket of simpler and lighter construction than prior art brackets.

Abstract: A metal post support ground spike is disclosed having a post receiving socket, and a flat plate. The flat plate is welded to four walls of the post receiving socket. The post support may also comprise a blades portion welded to the flat plate. The blades portion, post receiving socket and flat plate may all have reinforcement lines stamped therein and may comprise metals of varying thickness and rigidity. The flat plate may comprise the thickest and most rigid metal, whereas the post receiving socket and/or the blades may be made from a thinner and/or less rigid metal.

Abstract: A ground spike is disclosed having a plurality of blades and a flat plate secured thereto. The blades each have a reinforcement deformation proximal to a longitudinal outer edge. The reinforcement deformation may be a reinforcement line stamped therein, may be a bent outer edge, or the like. Objects may be attached to the flat plate, thereby securing such objects to the ground when the ground spike is used. The ground spike may have a post receiving socket secured to the flat plate. Each component may comprise metals of varying thickness and rigidity or other suitable materials.
