Abstract: A radar system to detect and track objects in three dimensions. The radar system including antennae, transmit, receive and processing electronics is all in a small, lightweight, low-cost, highly integrated package. The radar system uses a wide azimuth, narrow elevation radar pattern to detect objects and a Wi-Fi radio to communicate to one or more receiving and display units. One application may include mounting the radar system in an existing radome on an aircraft to detect and avoid objects during ground operations. Objects may include other moving aircraft, ground vehicles, buildings or other structures that may be in the area. The system may transmit information to both pilot and ground crew.

Abstract: This disclosure is directed to techniques to improve the mechanical reliability and strength of slot array antennae created using printed circuit board (PCB) technology. In some examples, a multi-layer PCB may have a limit on the length and width dimensions. Therefore, a larger slot array antenna may require two or more PCBs to create the full size of the antenna. This disclosure describes techniques to securely connect the two or more PCBs to withstand environments where the slot array antenna may be placed under mechanical stress, such as vibration. A PCB based antenna may define the walls of radiating waveguides with vias between the layers of the PCB. Mechanical fasteners may pass through some of the existing vias to secure the PCB to a support structure, such as a feeding waveguide, as well as to secure one PCB to other PCBs.

Abstract: A slot antenna with the low-cost, light weight features of an SIW antenna combined with the efficiency of a metallic antenna. The antenna of this disclosure may use printed circuit board manufacturing (PCB) processes to form the radiating portion to create slots and waveguide features with accurate dimensions and accurate positions. Like a metallic antenna, radio frequency (RF) energy passes through air in the radiating waveguides instead of a substrate, which means low insertion loss and high efficiency. Examples of the antenna of this disclosure may include a metallic coupling waveguide to carry the RF energy from the RF generating components of the radar system to the radiated branch waveguides. The metallic coupling waveguide may be configured to provide structural support to the PCB radiating portion as well as backwards compatibility to retrofit existing radar systems with the antenna assembly of this disclosure.

Abstract: An integrated slot waveguide antenna array for a radar system. The antenna array may include substrate integrated waveguide (SIW) elements, transmit, receive and processing electronics in a lightweight, low-cost, highly integrated package. The combination of antenna layout, specific dimensions of SIW features, including vias, terminal edges and slot placement may allow an efficient transmit and receive radar pattern as well as consistent, reliable and low cost manufacturing.

Abstract: A method of fabricating components for a three-dimensional circuit structure includes providing a printed circuit board (PCB) having a top surface, an opposing bottom surface, and an end section. A first angled channel is formed in the top surface at the end section, with the first angled channel extending to an edge of the end section and dividing the end section into a first end portion and a second end portion. The PCB material is removed from the top surface at the first end portion to form a first support member having an upper surface at a preselected distance below the top surface. A second angled channel is formed in the bottom surface at the end section of the first PCB, with the second angled channel extending to the edge of the end section and being adjacent to the first support member. The PCB material is removed from the bottom surface at the second end portion to form a second support member having an upper surface that is contiguous with the top surface of the PCB.

Abstract: A cooking apparatus including a pan and a detachable support and a method for using the same to cook and flavor food are provided. The pan includes a bottom and a plurality of perforations arranged therein. The detachable cylinder includes a bottom surface, a generally circular sidewall extending upward from the bottom surface, and a plurality of fasteners formed on the bottom surface. The plurality of fasteners are sized and arranged to correspond with a sizing and arrangement of a subset of the perforations. The detachable cylinder is optionally secured to the pan by coupling the fasteners to the subset of perforations and by rotating the detachable cylinder in a first direction to move the fasteners into a locked position. The detachable cylinder is optionally disengaged from the pan by rotating the detachable cylinder in a second direction to move the fasteners into an unlocked position.

Abstract: A barbecue tongs is provided wherein the arms are yieldingly outwardly biased. The tongs incorporate an arm pivot limiter for each of outward pivotal movement and inward pivotal movement as well as an arm lock that holds the arms in an almost fully jaws closed configuration for convenient storage. The tongs utilize a slidable U-shaped sleeve at the rear end which can have either one of two positions selected by a user. In one position, the arm lock is operational while in the second position the outward pivot limiter is operational.

Abstract: A juicer includes a reservoir with a spout and an annular rim having an extended portion with at least two holes. An extractor having an upright convex extracting dome is surrounded by an annular trough having openings therethrough. The extractor has a strainer element and is removably seated on the annular rim of the reservoir. The extractor has at least one peg that can mate with the at least two holes in at least two positions. The strainer element covers the spout when the peg is mated with one of the holes in a first position. The strainer element does not cover the spout when the peg is mated with another of the holes in a second position. When mated, the extractor cannot rotated relative to the reservoir. A resilient, elastomeric foot on the reservoir prevents rotation of the reservoir relative to a supporting surface.
