Abstract: A multi-band low-profile antenna includes a conductive ground-plane element; a first radiator element mounted on the ground-plane element to define a first vertical loop; a second radiator element mounted on the ground-plane element to define a second vertical loop; and a coupling element mounted on the ground-plane element to define a vertical coupling loop, with one end portion of the coupling element being connected to a feed terminal. In at least one embodiment, the first radiator element and the second radiator element are of such dimensions and are so disposed as to be parasitically coupled to each other, to cause the first radiator element to resonate at a first predetermined VHF frequency and to cause the second radiator element to resonate at a second predetermined VHF frequency.

Abstract: In systems for reading pixel data from an array of horizontal m-bit rows of CCD image detectors, pixel data loaded in parallel from a row of the array into an m-bit shift register is transferred in parallel from the m-bit shift register into other data storage device(s) having a plurality of output ports and sensed by a plurality of output amplifiers respectively connected in parallel to the output ports of the other data storage device(s).
