Abstract:
Wheeleta comprises a regular wheelchair to which, the front area has been altered to adapt a pair of crutches. Wheeleta crutch assembly includes the wedges, a sheath, a spear and the handle with under arm cushion area and the bar. It will attach the handle to the spear by lifting the button and introducing the bar into the spear until the previously established height is reached. The button is liberated and the height is fixed. The wedge is attached to the end of the spear and kept in place by a pivot with an open end with a rotating metal blade. The crutches could be out of way by twisting the spear in its own sheath and utilized by the user when rises to go out or entering the chair. The crutches could be removed from the sheath by lifting and pushing the crutch. The wedges also, could be completely removed from the spear by twisting a rotating metal blade at the end of the crutch pivot. The crutch handle with bar could be removed out of the spear and used to reach objects.
Abstract:
A personal protective headgear is an apparatus fully enclosing a user's head, protecting not only from potential contamination of breathing air but also from potential physical damage. A facial shield is hermetically sealed around the front-facing portion of the apparatus, preventing entrance of unfiltered air. Fans direct air through a set of filters, thus cleansing air entering the apparatus. The apparatus may further be equipped with a variety of interactivity modules, including cameras, speakers, lights, displays, and more. A set of sensors may be utilized to monitor the user and the user's surroundings in different conditions. The apparatus may also include wireless capabilities that allow the wearer to transfer information to and from a remote user, thereby allowing the user to follow instructions or otherwise interact with a guide or other such remote companion. Swappable battery packs allow the user to avoid losing power, even while replenishing power supplies.
Abstract:
A vehicular camera system is used to improve a driver's visibility around the entire perimeter of their vehicle. The vehicular camera system includes a vehicle, a plurality of cameras, and at least one display panel. The plurality of cameras is external mounted around the vehicle and is preferably positioned at the front, the rear, the left side, and the right side of the vehicle. The plurality of cameras is used to capture real-time footage of the area surround the vehicle and transmits this real-time footage to the display panel. The display panel is peripherally mounted to the steering wheel so that the driver is able to easily view the real-time footage that is visually outputted by the display screen.
Abstract:
A system for automatically monitoring provisioning in a DSL network is disclosed. The system is operable to query network elements in the DSL network for information related to the provisioning of DSL services. Thereafter, the system analyzes the information to identify points of delay and/or failure in the provisioning process. If a delay exceeds a threshold value, an administrator is notified.
Abstract:
An electrostatic charge deionizing lighting conductor has two frameworks having different geometries and being electrically separated from one another, insulators which electrically separate the frameworks from one another and must support the frameworks in the insulators and being electrically insulated, each of the insulators being provided with a variable dielectric, so that each of the insulators, when it counter balances an energy within it, annuls a saturation of electrical charges in an atmosphere of a protected area which are responsible of thunderbolt formation, its scope being variable according to a geographic area to be protected and the values being of about 650 meter radius.
Abstract:
The present invention relates to the use of non-deactivatable security compositions comprising the combination of at least two types of particles of oxide materials, where said particles have a different size and/or morphology, and where the inorganic oxide materials have at least one transition metal or one lanthanide element, and radiofrequency wave absorption properties. The invention also relates to security articles, documents or elements incorporating these compositions, as well as to a method and to a system for detection thereof.
Abstract:
The present invention relates to a method for preparing hierarchically ordered structures of inorganic phosphate particles, homogeneously deposited on the surface of a phyllosilicate, which is characterized in that it comprises the following steps: a) obtaining an acid solution of precursor compounds of an inorganic phosphate; b) preparing a dispersion of particles of a phyllosilicate in aqueous medium and acidifying the phyllosilicate dispersion by adding at least one acid, thereby obtaining an acid dispersion; c) mixing the acid solution obtained in step a) with the dispersion obtained in step b); and d), with stirring, adding a base to the mixture obtained in step c) until the required pH value for precipitating the corresponding inorganic phosphate on the phyllosilicate particles has been achieved, resulting in a hierarchically ordered structure of homogeneously distributed submicrometric or nanometric inorganic phosphate particles supported on the phyllosilicate surface.
Abstract:

Abstract:
A control method and apparatus are provided to convert a DC voltage into alternating voltage. The apparatus includes a first inverter and a second inverter to generate a first alternating voltage and a second alternating voltage, respectively. Also included is an interphase transformer to combine these alternating voltages in parallel to obtain a first resulting alternating voltage. The apparatus also includes a third inverter and a fourth inverter to generate a third and fourth alternating voltage, respectively. These are combined to form a second resulting alternating voltage. The second resulting alternating voltage is displaced in phase approximately 180° in relation to the first resulting alternating voltage.
