摘要:
A radome-reflector assembly includes a generally domed reflector having a peripheral rim and a radome assembly. The radome assembly includes: an annular ring having a front wall and a side wall: a disk that fits within the ring: and an RF-compliant absorber, wherein the rim of the reflector fits within the side wall. The radome assembly further comprises a clip that engages the rim and the ring to secure the reflector to the radome assembly.

An improved signal light and method for making an improved signal light is disclosed. For example, the improved signal light includes a housing, at least one outer lens and at least one or more second type of light emitting diodes (LEDs) deployed in the housing. The at least one or more second type of LEDs includes a pump, a phosphor and a filter having a cutoff point less than or equal to 540 nanometers (nm). The at least one or more second type of LEDs also has a pump peak wavelength less than or equal to 430 nm and has a phosphor with a peak wavelength greater than 575 nm.
摘要:
A method and apparatus for enhancing the electrical performance of a reflector antenna. A boom disc mounted upon a feed waveguide supporting a subreflector is dimensioned and positioned for reflection cancellation against the reflected components from the reflector vertex region in the direction of edge illumination half angle T. A dielectric sleeve or RF absorbing material may be placed between the vertex region and the boom disc.

Systems and methods for determining implied spreads are provided. More particularly, implied spread financial transactions are generated using information from requests for quotes (RFQs). An RFQ processor module may focus the calculations performed by an implied spread determination module. A financial instrument associated with an RFQ may be provided to the implied spread determination module to trigger the determination of whether implied orders exist related to that particular financial instrument.
摘要:
A reflector antenna feed RF seal between an antenna base, a feed hub and a vertex plate. The RF seal formed via a generally annular gasket of compressible material adapted to seat around an outer diameter of the feed hub. The gasket having an outer diameter greater than a diameter of a joint between the feed hub and the antenna base and less than an outer diameter of the vertex plate. The gasket compressed within a cavity formed between the antenna base, the feed hub and the vertex plate as the feed hub is seated within the antenna base.
摘要:
Control apparatus (1) for selectively applying a mains AC electrical supply (3) to an electrical appliance (4) in response to a remote signal received via a cellular telecommunications network comprises a housing (8) within which an electrical socket (14) for providing power to the appliance (4) is integrally formed. An electrical plug top (10) on a cable (12) extending from the housing (8) is provided for coupling to the mains supply (3). A switch circuit (15) under the control of a microcontroller (19) controls the mains supply (3) to the electrical socket (14). A communications circuit (20) which is adapted for communicating with a cellular telecommunications network receives SMS control messages, and the microcontroller (19) is responsive to the SMS control messages for in turn operating the switch circuit (15) to selectively switch the mains supply (3) to the appliance (4). A power supply circuit (28) independent of the mains supply (3) powers the control apparatus (1). A volt meter (22) monitors the presence of the mains supply (3) and an amp meter (24) monitors the current being drawn by the appliance (4). The microcontroller (19) is responsive to the volt meter (22) detecting the mains supply and the amp meter (24) detecting the absence of current being drawn by the appliance (4) when the switch circuit (15) is in the closed circuit state for determining the operational status of the appliance as faulty.
摘要:
An interconnection retaining a radome upon a periphery of a reflector dish has a plurality of curved channel portions, each of the channel portions provided with an open periphery slot and an open retention slot. The periphery slot dimensioned to receive the peripheries of the radome and reflector dish. The channel portions are arranged end-to-end adjacent to one another, encircling the peripheries of the radome and reflector dish seated within the periphery slot. A gap may be provided between one or more of the channel portions. A link member is seated within the retention slot at an end of each adjacent channel portion. The retention slot at the end of each of the adjacent channel portions is crimped upon the link member. The link member may be, for example, a portion of threaded rod or a molded portion of polymer material.

The subject invention relates to nucleic acid sequences for detection of mutations in a PKD-1 or PKD-2 gene, as well as biomarkers for ADPKD. The invention further relates to methods for diagnosing ADPKD in an individual, and kits for performing the methods of the invention. The invention also provides a method for determining in an individual the presence or absence of a mutant PKD gene.
摘要:
The present invention relates to a switching system for interconnecting a plurality of computer user terminals or workstations each having user interface devices, including a keyboard, a video display unit, and a cursor control device or mouse (KVM), with a plurality of computers in a computer network, allowing a user to access any one or more of said computers from the user interface devices of a single terminal or workstation. It is denoted “high end” because of the potentially large number of computers which may be interconnected with the system.
