International Classification:

H01L 3900

US Classification:

257662, 257663, 257664, 333109, 333112, 333118, 333119, 333115, 333127

Abstract:

A directional coupler that has a small package size and repeatable electrical characteristics. The directional coupler includes a low temperature co-fired ceramic (LTCC) substrate with several layers. Electrical components such as resistors and capacitors are integrated within the LTCC substrate. A transformer is attached to the upper surface of the LTCC substrate and is electrically connected to the resistors and capacitors. The LTCC substrate has electrically conductive vias extending therethrough. The vias are used to make electrical connections between the layers of the LTCC substrate.

Abstract:

A power splitter that has a small package size and repeatable electrical characteristics. The power splitter includes a low temperature co-fired ceramic (LTCC) substrate with several layers. Electrical components such as resistors and capacitors are integrated within the LTCC substrate. A transformer is attached to the upper surface of the LTCC substrate and is electrically connected to the resistors and capacitors. The transformer provides impedance matching and dividing functions. The LTCC substrate has electrically conductive vias extending therethrough. The vias are used to connect the power splitter to an external printed circuit board. The vias are also used to make electrical connections between the layers of the LTCC substrate.

Abstract:

A power splitter that has a small package size and repeatable electrical characteristics. The power splitter includes a low temperature co-fired ceramic (LTTC) substrate with several layers. Electrical components such as resistors and capacitors are integrated within the LTTC substrate. A transformer is attached to the upper surface of the LTCC substrate and is electrically connected to the resistors and capacitors. The transformer provides impedance matching and dividing functions. The LTCC substrate has electrically conductive vias extending therethrough. The vias are used to connect the power splitter to an external printed circuit board.

International Classification:

A47C 7/74

US Classification:

29718014

Abstract:

A cooling pad includes a bottom section, a top section, and a middle section which together form a contoured surface to support a person's back. The contoured surface includes concave and convex sections, providing ventilated pockets which allow air to flow to a person's back. Inside the middle section there are intake holes, located on either side of the cooling pad, and exhaust holes, positioned atop and below the middle section. The intake holes allow air to be brought in from outside, while the exhaust holes direct air to cool a person's back. Fan and power systems are stored inside the middle section. The fan blows air through the exhaust holes. The system as a whole is designed to utilize negative pressure to bring fresh air in from the intakes, replacing the air the fan pushes through the exhaust holes. The resulting airflow prevents back sweat from occurring.
