Dielectric conduits for the propagation of electromagnetic EHF signals include an elongate body of a dielectric material extending continuously along a longitudinal axis between a first terminus and a second terminus. At each point along the longitudinal axis, an orthogonal cross-section of the elongate body has a first dimension along a major axis of the cross-section, where the major axis extends along the largest dimension of the cross-section. The orthogonal cross-section also has a second dimension along a minor axis of the cross-section, where the minor axis extends along a widest dimension of the cross-section that is at a right angle to the major axis. For each cross-section of the elongate body, the first dimension is greater than the wavelength of the electromagnetic EHF signals and the second dimension is less than the wavelength of the electromagnetic EHF signals.

An integrated circuit includes a first lead frame and a second lead frame that extend from an overmolded circuit assembly. Each of the lead frames includes a piercing portion to pierce through insulation on a corresponding electrical conduit. The piercing portion of the lead frames also provides a wrap around feature to mechanically secure the wire to the corresponding electrical conduit. In this manner, several processes can be eliminated and are not required for the desired mechanical and electrical connection of the integrated circuit lead frame to corresponding electrical conductors.

Described herein are foamable compositions and methods of making foamed compositions. The foamable composition comprises at least one polymer and a foaming agent. The foaming agent comprises a talc or a talc derivative. The polymers described herein comprise a substantially non-halogenated polymer. One or more additives are added to render the compositions flame retardant and/or smoke suppressant. Also described are Power over Ethernet (PoE) cables, having at least one electrical conduit comprising an electrically conductive core, an insulation that at least partially surrounds said electrically conductive core and a polymeric separator extending from a proximal end to a distal end and having at least one channel adapted for receiving the at least one electrical conduit. The PoE cables are capable of carrying about 1 watt to about 200 watts of power.

Non-masonry building block components, including a standard hollow-bodied block component with horizontal and vertical locking capabilities which removes the need for bonding material such as glue, mortar or other adhesives. Modified dovetails on the upper and lower surface of the building components prevent vertical movement while resistance locks on each end of the block prevent horizontal movement. Typically, use of the non-masonry building components would allow for constructing permanent or temporary structures having vertical and horizontal channels in which to allow plumbing or electrical conduit. The incorporation of materials, such as sand or similar substance, would form a bullet-resistant barrier for use in military operations. Additionally, structures formed from the block components could easily be assembled or disassembled on site without the need for skilled labor, specialized tools, demolition and clean up.

An adjustable ground clamp for easy positioning onto electric conduits of different diameters. A first and a second jaw are pivotally connected and have differently angled jaw surfaces. A distal end of the first jaw has an elongated hole and a distal end of the second jaw has a curved fork having a slot for receiving a bolt with a cylindrical nut. A fastener connects a ground conductor or wire to the ground clamp. The differently angled jaw surfaces, curved fork, cylindrical nut, and the elongated hole result in a ground clamp capable of securely holding electrical conduits of different sizes or diameters without disassembly. The jaws may be easily separated for placement of an electrical conduit without separating or detaching any parts from the ground clamp, making attachment to an electrical conduit quick, easy, and secure.

A magnetic cable fastener includes a magnetic fastener, a boss, a base, and a loop coupler attached to the base. The loop coupler is attached to the base and is operable to attach to another structure. The loop coupler may be a cable, wires, electrical conduit, rope, adjustable strap, and a tie wrap or suitable object. According to one embodiment, the loop coupler may further include at least two fingers. The fingers are operative to flex or compress appropriately to permit the cables to enter the fingers. According to another embodiment, the loop coupler is a solid loop to permit for example, a cable strap to be inserted and attach the cable strap to the loop coupler. Thus, the magnetic cable fastener may secure one or more cables via the loop fingers or solid loop or other suitable cable coupler.

A detachable cover and base for housing open standard electrical wiring, the cover and the base having shoulders portions which readily engage and disengage. When coupled the shoulder portions form tubular projections that hold electrical conduits containing electrical wiring. A gasket is provided between the base and the cover to form a waterproof barrier. The tubular projections are perpendicular to walls of the cover and the base, and allow electrical wiring to be connected from multiple directions within a residence.

A structural truss system and electrical conduit for suspended mounting of electrical components such as stage lighting and remote controlled equipment featuring an elongated support beam with removable endcaps and a sidewall. The sidewall is cooperatively engageable with the support beam along substantially its engire length and allows access to the conduit formed inside when engaged with the support beam. A mounting track formed on the exterior surface of said bottom wall of the support beam and provides a slidably engageable mount for component mounts that attach to electrical components such as lights thereby providing positioning ability for the attached components. One or a plurality of electrical plugs or similiar attachments communicate through the sidewalls with wires running in the conduit and allow the electrical components to be properly situated in the mounting track and then plugged into the electrical power or control signals provided by the internal wiring.

A semiconductor device package having an embedded three-dimensional interconnect structure and a process for making such a package is provided. One or more ball conductors are attached to a major surface of a substrate that provides at least an electrical conduit from the ball conductor to an opposite major surface of the substrate. The substrate can also provide an interconnect between solder balls. The combination of solder balls and substrate is encapsulated in the semiconductor device package. The ends of the signal conduits are exposed on one major surface of the device package, while a portion of the ball conductors is exposed on the opposite major surface of the device package. The ball conductors and signal conduits provide signal-bearing pathways between the major surfaces of the package. Contacts created by the back grinded ball conductors are used to form a package-on-package structure by coupling with contacts from another package.
