Abstract: System and methods of notifying a customer of a maintenance service to be performed on a vehicle are described herein. The systems include a communication component to communicate with the vehicle via a network and at least one processor in communication with the communication component.

Abstract: There is provided a kit comprising a base member adapted to be releasably attached to an upper region of a vehicle; a pole member comprising a first end that is adapted to be releasably coupled to the base member; an identification tag adapted to be mounted on the pole member and at a predetermined distance from the first end; and a light adapted to be positioned on the pole member. Such a kit is quite useful for tracking vehicles such as vehicles left outdoors that can be covered with ice and snow.

Abstract: An identification kit includes a first tag member and a second tag member. The first tag member is for mounting onto a rearview mirror of a vehicle and has at least one first visual identifier displaying a unique identification code and a first passive RFID tag. The second tag member for mounting onto a vehicle key and has at least one second visual identifier displaying the unique identification code and a second passive RFID tag.

Abstract: A digital beam-forming network for an array antenna having N>1 antenna ports, to be associated to respective antenna elements, and M?1 beam ports (BP), corresponding to respective antenna beams. The digital beam-forming network comprises a plurality of complex weighting elements interconnected through summing nodes. At least one of the complex weighting elements is connected to either two antenna ports, to be associated with respective antenna elements which are arranged symmetrically with respect to the symmetry axis, or two beam ports corresponding to respective antenna beams pointing toward directions which are symmetrical with respect to the symmetry axis, or both. The digital beam forming network can be a part of an array antenna comprising N antenna elements, NS of which are arranged according to an array pattern having a symmetry axis, NS being an even integer different from zero.

Abstract: Multiple shaped-beam or scanned beams reflector or lens antenna configured so as to have the radiating elements outside the focal plane (imaging) with improved characteristics in terms of gain and coverage area. Said antenna (FIG. 1) essentially consists of a reflector or a lens (1), a certain number of radiators (3) positioned outside the focal plane, a Beam Forming Network (BFN). It classifies in the technical field of multiple shaped-beam antennae and is applicable to radars, telecommunications in general and to space telecommunications in particular. Its most significant advantage consists in its use as transmitter antenna since in it the electric performance/complexity ratio is improved.

Abstract: A multishaped beam direct radiating array antenna has a network on which high power beam forming sub-networks are disposed. The network is interposed between radiating elements and RF power amplifiers. This antenna is in addition constituted with a traditional network in which power combiners, phase shifters and inter-connection lines are provided. The most significant feature is that, with the help of the high power beam forming network, the correct amplitude and phase values, at the radiating element level, may be achieved without differentiating the RF power amplifier output levels, thus keeping its efficiency as high as possible. One of the advantages this configuration presents is the possibility to utilize only one antenna in comparison of the previous techniques in which the same results were obtained utilizing many radiating panels.

Abstract: The invention provides an antenna for transmitting or receiving closely spaced multibeams with very low level sidelobes comprising, for each beam feed, a primary feed feeding one or more main elements surrounded by secondary elements some of which are shared between several adjacent beam feed, the power supplied by the primary feed being distributed to the different elements by means of couplers. According to the invention, each shared element is fed by each of the power transmission lines feeding the main element (E1, E'1) of said adjacent beams through a coupler, each transmission line of a secondary radiating element (L2, L'3) comprising at least two couplers (C1, C2) in series.
