Abstract: The present invention relates to an electronic beam steering antenna, that includes a plurality of antenna elements disposed in a spaced apart manner with respect to each other, wherein beam steering occurs along an axis connecting the plurality of antenna elements, wherein a feed line is provided between each of the adjacent antenna elements, and wherein each of the feed lines are connected in series along said axis, and wherein each antenna element radiates a mixed signal generated by combining frequencies of first and second input signals, wherein the first input signal is received from an output of a feed line preceding said antenna element and has a frequency which varies with change in beam pointing angle along said axis.

Abstract: The present invention provides a vehicle safety sensor system comprising a processor; a first radar sensor configuration to scan a first wide area; a first auxiliary sensor configuration to scan a second wide area; a second radar sensor configuration to scan a first narrow area, wherein the first narrow area is smaller than the first wide area; and a second auxiliary sensor configuration to scan a second narrow area, wherein the second narrow area is smaller than the second wide area. The system is configured to operate in a first mode wherein data from the first radar sensor configuration and data from the first auxiliary sensor configuration is fused together to provide a first set of fused data; and the processor is configured to detect objects from the first set of fused data.

Abstract: A radar system comprising an array of squintable elements, one or more tuners and a controller. A squintable element is an array of two or more resonant elements, wherein a first plurality of the squintable elements are configured to transmit an electromagnetic signal at a first frequency and a second plurality of the squintable elements are configured to receive a reflection of the electromagnetic signal. The controller is configured to control the one or more tuners to alter the frequency of the electromagnetic signal such that the first plurality of squintable elements transmits the electromagnetic signal at a second frequency, wherein the second frequency is different to the first frequency, and altering the frequency of the electromagnetic signal deflects the electromagnetic signal.

Abstract: The present invention provides a radar for a road vehicle. The radar comprises a beam-forming network having a first number of input ports and a second number of beam-forming ports, wherein the first and second numbers are greater than 1; a first number of antennas, wherein the first number of antennas is for receiving signals and each antenna in the first number of antennas is connected to a respective input port of the beam-forming network; a second number of receivers, wherein at least two receivers can operate simultaneously, each receiver is connected to a respective beam-forming port of the second number of beam-forming ports; a third number of antennas, wherein the number of antennas is for transmitting a signal, wherein the third number is greater than 1; and a processing means configured to determine the position of an object relative to the radar based on the magnitudes of the signals received by the receivers.

Abstract: The present invention provides a circularly polarised, CP, antenna device for multiband GNSS. It comprises a spiral antenna and a high impedance surface, HIS, comprising a conductive layer comprising a first region and a separate second region, and a ground plane. The first region of the conductive layer is provided with at least one resonant element of a first resonant frequency and the second region of the conductive layer is provided with at least one resonant element of a second resonant frequency.

Abstract: The present invention provides an amplitude comparison monopulse radar system. The system comprises a beam forming network for coupling to the phased array antenna. The beam forming network is adapted to change the phase delays between the antenna elements in a phased array antenna such that the monopulse radiation pattern is scanned over an angular range through space.

Abstract: The present invention relates to electrical enclosures having a cabinet and a door connected by hinges and in particular to a hinge which allows a door, while closed, to be flush with a surface that surrounds the perimeter of the cabinet door opening. The hinge system utilizes a spring that pushes the door in a direction that is generally normal to and away from the cabinet, creating a space between the peripheral flange on the door and the surface that surrounds the cabinet door opening thus allowing the door to swing freely as it is opened and closed. The door can be held closed by use of various latching systems. While the door is in the closed position, latches near the hinges will compress the hinge springs, eliminating the space between the door and the cabinet opening.

Abstract: A firewood rack or the like which includes two upright closed frames, a closed base frame, and a hipped roof which mounts on the upright frames.
