A system comprising a self-propelled device and an accessory device. The self-propelled device includes a spherical housing, and a drive system provided within the spherical housing to cause the self-propelled device to roll. When the self-propelled device rolls, the self-propelled device and the accessory device magnetically interact to maintain the accessory device in contact with a top position of the spherical housing relative to an underlying surface on which the spherical housing is rolling on.

A fastening apparatus is configured to fasten an electronic device to other objects. The fastening apparatus includes a fastening base, a connection assembly pivotably connected to the fastening base, a first magnet, and an adhesive layer positioned on the fastening base configured to fix the fastening base to other objects. The connection assembly includes a connection portion and a second hinge positioned on the connection portion. The first magnet is positioned on a side of the connection portion to detachably grip the electronic device, and the second hinge is positioned on other side of the connection portion opposite to the first magnet. The second hinge is pivotably connected to the fastening base.

Disclosed is a protective shell for a tablet personal computer. The protective shell comprises: a protective film, a limiting frame and a protective shell body; wherein the protective film is arranged at an upper portion of the limiting frame, four sides on a frame body inner side surface of the limiting frame being each provided with a limiting bar; a contact portion of the limiting frame and the protective film is in a horizontal plane, the limiting bar being operable to limit the tablet personal computer to prevent the tablet personal computer from moving in the limiting frame; and the limiting frame is fixed in a snap-fit manner to the protective shell body. The technical solution according to the present invention has the advantage of a better protection effect.

A camera device comprises: a camera section which includes a camera base and a camera case disposed on the camera base and housing a pickup lens therein; and an attaching device which includes a magnetic attraction box and a fixing device formed integrally with the magnetic attraction box and fixable to an automobile, wherein one of a front surface of the magnetic attraction box and a back surface of the camera base is provided with a magnet capable of attracting an iron family metal and the other of the front surface and the back surface has properties of an iron family metal attractable by the magnet, and the fixing device is a fixing device having a grooved rail, double bar drag hooks and a spring, the magnetic attraction box being formed integrally with the grooved rail.

An accessory system for a vehicle includes a housing having a base attached to the vehicle and a projection extending from the base, the projection being fluidly coupled to a duct of the vehicle. The accessory system also includes a first vehicle accessory having a cavity configured to selectively receive the projection of the housing to selectively attach the first vehicle accessory to the housing in an engaged state.

This mobile terminal charging device has a support plate in which the front surface-side part is where a mobile terminal is installed, a charging coil disposed facing the support plate on the rear surface-side of the support plate, a plurality of detection coils concentrically disposed in the charging coil on a surface opposite the support plate, and a control unit connected to the detecting coils. When a charging operation is carried out, the control unit compares the difference between a voltage value detected using a first detecting coil among the plurality of detecting coils, and a voltage value detected using two detecting coils from a group comprising the first detecting coil and at least one detecting coil disposed outward of the first detecting coil. In addition, the control unit executes a safety operation in accordance with the results of the comparison.

A self-propelled device includes a spherical housing and an internal drive system. The self-propelled device can further include an internal structure having a magnet holder that holds a first set of magnets and an external accessory comprising a second set of magnets to magnetically interact, through the spherical housing, with the first set magnets.

A suction mount includes a magnetic assembly, a main body, and a suction cup. The magnetic assembly includes a magnet and is configured to magnetically fix a cellphone through the magnet. The main body is rotatably connected to the magnetic assembly. A universal ball head is provided between the main body and the magnetic assembly. The universal ball head is connected to the main body and the magnetic assembly, respectively. At least one of the main body and the magnetic assembly is rotatable relative to the universal ball head, such that the magnetic assembly rotates in any direction relative to the main body. The suction cup is located at a side of the main body facing away from the magnetic assembly. The suction cup is attached to an external support plane to form a closed chamber, and the suction cup is automatically adhered to the external support plane.

A support apparatus includes a main element supported by lanyard. The main element includes one or more channels for supporting an object such as a firearm in a substantially vertical position. The support apparatus may include a hook or other fastener for removably coupling to a vehicle or other fixed object. In some embodiments, channel dividers are semi-spherical in shape, and may be generally semispherical with a teardrop (i.e., drooping) shape. The channel dividers may be sacks or vessels filled with an elastic type substance (e.g., silicon) and be formed to elastically grip the firearm and provide a firm support.

A gearshift smartphone mount device includes a first panel that is structured to have a stem portion extending downwardly from a knob portion. A second panel is structured to have a stem portion extending downwardly from a knob portion and the second panel is attachable to the first panel such that the first panel and the second panel define a gear shift knob. A shaft channel in the first panel is aligned with a shaft channel in the second panel to defines a hole which insertably receives a gear shift shaft of a vehicle. A magnet is integrated into the first panel and the second panel and the magnet magnetically engages a personal electronic device to facilitate the personal electronic device to be visible to a driver of the vehicle.
