Abstract: A tennis racket with a removable weight is provided. The tennis racket includes: (i) an upper portion, (ii) a handle, and (iii) a butt. The upper portion includes a mesh of wires. The handle secures the removable weight in a hollow space. The butt couples to the handle at bottom portion of the handle using threads.

Abstract: A case system includes an electronic device and the electronic device has a charge port. A case is provided and the electronic device is removably positioned in the case. The case is in electrical communication with the electronic device when the electronic device is positioned within the case. A pair of lights is provided and each of the lights is movably coupled to the case. Thus, each of the lights is positionable between a deployed position and a stored position. Each of the lights selectively emits light when the lights are positioned in the deployed position thereby facilitating the electronic device to take a picture. A charging unit is coupled to the case. The charging unit is in electrical communication with the electronic device when the electronic device is positioned within the case. Thus, the charging unit charges the electronic device.

Abstract: An antenna support structure for a remote vehicle comprises a tubular mast configured to demonstrate a non-linear response to radial force. The mast is rigid and configured to hold an antenna approximately perpendicular to a base of the mast at equilibrium during operation of the remote vehicle and elastically buckle in response to a predetermined radial force on the antenna. The support structure is also configured to return to equilibrium once the predetermined radial force is removed.

Abstract: A robotic assembly comprises: a mobile vehicle including mechanical components configured to operate the mobile vehicle in a manual mode of operation; a main power circuit for distributing a power signal to the electromechanical components and to external modules; an automation module connected to the mechanical components and operable to control and operate the mechanical components, and a power circuit configured to distribute power to the mechanical components and the external modules; a safety control module connected to the main power circuit, the automation module, and the mechanical components; a mode selector connected to the main power circuit; and emergency stop switches configured to prevent a flow of current to substantially all of the mechanical components and external modules in response to actuation of the emergency stop buttons.

Abstract: A touch screen navigation device for making purchases includes a memory to store a first descriptor that identifies a card used in commerce; a scannable identifier adapted to provide a second descriptor to a scanner; a display for displaying changeable information including an icon for the card; and an input to select the card. When the card is selected, the display takes the appearance of the card, and when the scannable identifier is scanned, the scannable identifier provides the descriptor in the memory that identifies the card. A page bar may scroll between pages of icons. Interfaces may be included for E-apps, E-games, paying-bills, music and video, books, and text messaging.

Abstract: An apparatus for dislodging a blocked plumbing system and method of use are disclosed. In one form, an apparatus for dislodging a plumbing system via a drain receptacle includes a substrate shaped to cover a portion of a drain receptacle. The substrate includes an exterior edge having a shape substantially similar to the drain receptacle and a top portion and a bottom portion and a hole extending through the substrate. A gasket is coupled to the exterior edge of the substrate and operable to create a substantially airtight seal between the drain receptacle and the substrate. The apparatus includes a valve extending through a portion of the hole and coupled to the top portion of the substrate and the valve selectively is operable to provide an open state and a closed state. The closed state provides a substantially airtight seal between a void volume and a vacuum source and the open state enabling a fluid communication path between the vacuum source and the void volume.

Abstract: An air deflector is adapted to be mounted on a vehicle and, by deflecting air, to reduce turbulence and drag associated with another vehicle which is towed by the first vehicle. The air deflector includes a side shield to extend outwardly and rearwardly outside a side wall of the front vehicle along the side wall, and a mounting for the shield, to mount the shield on the front vehicle. The side shield has an inner edge surface which defines an edge surface contour for facing the side wall of the vehicle in close proximity to such side wall. The mounting is adapted to accomplish the facing-close proximity relationship between the inner edge surface of the shield and the side wall of the vehicle. The mounting includes a post to insert in a substantially vertical opening provided on the front vehicle, and a brace. The post has a surface to extend outwardly and rearwardly and to abut the rear surface of the shield.
