The controller may be configured to determine whether the electrical power is no longer received by the resistive elements and operate the at least one blower drive to operate the blower motor to cool the resistive elements responsive to the electrical power no longer being received by the resistive elements.

Abstract: Television tuner emulation techniques are described. In an implementation, a television tuner is emulated through execution of software on a processing system by a computing device, the emulated television tuner includes functionality to obtain television content over an Internet Protocol (IP) based network. The functionality of the emulated television tuner is exposed to one or more applications that are executed by the computing device such that the application is not aware that the television tuner is emulated through execution of the software.

Abstract: A dry FCVS for a nuclear reactor containment is provided. The dry FCVS includes a housing and a round and/or elongated aerosol filter inside the housing for removing contaminant aerosols from gas passing through the housing during venting of the containment. The housing includes at least one inlet portion configured for directing gas into the aerosol filter during the venting of the containment and an outlet portion for gas filtered by the aerosol filter during the venting of the containment. The dry filtered containment venting system is arranged and configured such that when a flow of gas through the outlet portion is closed off at least one of convective, radiant and conductive heat transfer removes decay heat of aerosols captured in the aerosol filter.

Each of said pluralities of elements is engaged to a separate substrate which is engaged along one of the four edges. The substrates may be angled to adjust the footprint of the antenna.

Abstract: A radiator element for RF communications formed of a planar conductive material positioned upon a planar dielectric substrate surface. Two lobes formed of the conductive material have side edges abutting a cavity decreasing in cross section between the lobes. The cavity has a widest point configured to receive RF frequencies at the lowest frequency and a narrowest point configured to receive a highest frequency of the element. Opposing pairs of notches in the side edges of the lobes along the decreasing edges of the cavity enhance the frequency of operation for frequencies paired to the distance between the pairs of notches.

Abstract: A kit is provided. The kit includes a garden waste storage support structure, a plurality of wheels, and a plurality of attachment members. The garden waste storage support structure includes a base, a plurality of side walls extending from the base, and a plurality of legs fixed to the base. The base comprises a plurality of integrally formed openings therein. The plurality of side walls each extend from the base. Each of the plurality of side walls comprise a plurality of integrally formed openings therein. The base and the side walls define a structure interior. The plurality of support legs are fixed to the base underneath the structure interior for at least partly elevating the base and the structure interior. The structure interior is sized to support a garden waste bag above the ground to provide for air circulation around an underside of the garden waste bag.

Abstract: A auxiliary antenna system is provided for a portable electronic device such as a smartphone or cellular phone or pad computer. The system positions one or a plurality of auxiliary antennas in or on walls of a protective case surrounding the electronic device. An internal antenna on the electronic device is communicated an RF signal of increased strengths and bandwidth from an auxiliary antenna coupled thereto. Additional auxiliary antennas may be positioned on the case to increase both signal and bandwidth.

Abstract: An antenna element employable singularly or in an array and configured for concurrent RF transmission and receipt on a plurality of frequencies concurrently. The element is formed of conductive material on a substrate by a pair of substantially identical horns extending in opposite directions to distal tips. A cavity formed between the horns narrows to a narrowest point prior to curving. The element is capable of wideband RF communication on any frequency between a low frequency defined by the distance between the distal tips to a highest frequency defined by the narrowest point of the cavity. The antenna is especially well adapted for portable devices such as smartphones where concurrent cellular, Wi-Fi, and bluetooth communications may be accomplished with a single element.
