摘要:
A dual polarized reflector antenna assembly, provided with a reflector dish coupled to a feed hub with a feed port there through; a transceiver support bracket coupled to a backside of the feed hub; a circular to square waveguide transition coupled to the feed port; a square waveguide coupled to the circular to square waveguide transition; an OMT coupled to the square waveguide; the OMT provided with an OMT intersection between a square waveguide and a pair of rectangular waveguides oriented at ninety degrees to one another, an output port of each rectangular waveguide arranged normal to a longitudinal axis of the dual polarized reflector antenna assembly. Alternatively, a circular waveguide may be applied between the feed port and the circular to square waveguide transition, eliminating the square waveguide, or the rectangular waveguides may be extended longitudinally, also eliminating the square waveguide.

摘要:
The present invention relates to a comfortable type removable tongue position corrective anti-snoring & anti-suffocating device. The device is made of wire or band material provided with suitable elasticity and rigidity, including at least a fixer, an upper force piece which is connected with the fixer and lower force piece. The device is mostly applied on upper jaw. The force end of the upper force piece is designed to be suitable to the normal configuration of the soft palate palatine, and acts on the portion in front of the sensitive position of the soft palate to raise up the soft palate palatine and uvula upward/upward and backward suitably without causing nausea and discomfort of peripheral tissue. The force end of the lower force piece is designed to be suitable to the normal configuration of the big tongue, and acts on the portion in front of the sensitive position of the posterior of the tongue to press the big tongue downward/front downward without causing discomfort and nausea. Thus, depending on the co-action of the upper and lower force piece, the blocked respiratory tract could be expanded to prevent snore and remit sleep apnea syndrome.
摘要:
A microwave antenna feed arrangement provided with a unitary body with a feed bore between a launch end and a back end of the body. A plurality of coaxial annular grooves are located on the launch end of the body. An OMT bore in the body extends from a side of the body to the feed bore. The body may be further configured with an end cap to close the back end of the feed bore or a feed elbow for dual polarization operation. The body may be manufactured for example, by machining or metal injection molding.

A comfortable and viable and removable device of channel-type tongue position correction for anti-snoring. The device is made of wire or band material, including a fixer, an upper and nether force-components which are connected with the fixer. The device is mostly applied on upper jaw. The force end of the upper force-component is designed to be suitable to the soft palate palatine velum, and acts to raise up the soft palate palatine velum and uvula upward/upward and backward suitably. The force end of the nether force-component is designed to be suitable to the normal configuration of the corpora linguae (anterior tongue), and acts on the portion in front of the sensitive position of the hind half of the corpora linguae (anterior tongue) to press the big tongue downward/downward and forward. Thus, depending on the co-action of the upper and nether force-components, the blocked respiratory tract could be expanded to prevent snore and remit sleep apnoea syndrome.
