Abstract: The concepts, systems, circuits and techniques described herein are directed toward a spiral antenna which may be provided using additive manufacturing technology so as to provide an antenna capable of operation at frequencies which are higher than spiral antennas manufactured using standard photo-etch or printed circuit board (PCB) manufacturing processes.

Abstract: A wave phased array is manufactured using additive manufacturing technology (AMT). The wave phased array includes a radiator, a radiator dilation layer supporting the radiator, a beamformer supporting the radiator dilation layer, a beamformer dilation layer supporting the beamformer, and a substrate support layer supporting the beamformer dilation layer. At least one of the radiator, the radiator dilation layer, the beamformer, the beamformer dilation layer and the substrate support layer is fabricated at least in part by an AMT process.

Abstract: A reactive beamformer includes a radiator disposed within a substrate and configured to radiate a received electromagnetic signal, a plurality of receptors disposed within the substrate, each of the plurality of receptors configured to receive a portion of the radiated electromagnetic signal, and a plurality of signal lines. Each signal line of the plurality of signal lines is coupled to a respective receptor of the plurality of receptors to convey the portion of the radiated electromagnetic signal from the respective receptor and to provide the portion of the radiated electromagnetic signal to an output.

Abstract: A method and apparatus for recording electronic data onto a portable computer-readable medium to be given to an end user for allowing the end user to review the electronic data in a private setting with a personal computer. The publisher includes a recorder for recording the electronic data on the portable computer-readable medium, an automated feeder for supplying the portable computer-readable medium to the recorder without intervention by an operator, and a user interface presenting the operator with one or more options that the operator can select to enter a command for controlling operation of the publisher. A printer is provided for printing onto a surface of a label at least variable label content that is related to the electronic data that can be retrieved from the computer-readable medium and reviewed by the end user.

Abstract: An accessory mount (20) for a portable instrument (26) is provided. The device includes a housing (28a and 28b) and a recess (30) located in the housing. The accessory mount also includes a frame (24) received within the recess and a fastener member (36a and 36b) attached to the frame for selectively attaching the frame within the recess. The accessory mount also includes a slot (42) that is partially formed with the frame for selectively attaching and/or positioning equipment, such as an adapter (22), to the device, thereby permitting operation of the device without requiring the use of both hands of an operator.

Abstract: A security apparatus for selectively releasable secured coupling of a displayed product to a multiconductor cord to preclude unauthorized uncoupling of the displayed product from the multiconductor cord, comprises a housing having a base portion with an adhesive product facing surface, and a cover portion mounted on the base portion. A product detector on the housing is responsive to the secure attachment of the displayed product to produce a first signal, and to detachment of the displayed product, corresponding to the unauthorized uncoupling of the displayed product from the multiconductor cord, to produce a second signal. The multiconductor cord terminates in a connector member connectable to a co-operating receptacle portion within the housing, thereby electrically interconnecting in signal conducting relation the product detector and an alarm system, such that the alarm system is quiescent in response to the first signal and produces the warning in response to the second signal.

Abstract: A device and process are disclosed for indicating clearance requirements of an aircraft maneuvering on a surface such as an apron, taxiway or flight deck. The device has an electromagnetic generation mechanism for generating a high intensity, low diffusing electromagnetic beam, and a projecting mechanism for securing the electromagnetic generation mechanism to the aircraft and projecting the beam toward a projection region. The projection region extends axially and in alignment with the distal end, and from the surface upward. In one embodiment, the electromagnetic generation mechanism is a laser that outputs a laser beam in the visible light spectrum. The beam produces an image upon the surface within the projection region, or upon an obstacle in the aircraft's path. Thus, the pilot can ascertain the clearance requirements by observing the projected images on the runway surface.

Abstract: A vapor generator is provided for producing vapor such as steam to be used for heavy oil recovery and the like. The vapor generator includes an octagonal cross-section furnace, which has evaporator surface arranged to allow for heating of said fluid to final evaporation in a relatively low heat flux portion of the generator to lessen the likelihood of scale formation on heat transfer elements of the vapor generator.
