Abstract: In an opto-electronic device utilizing a band of light for quantitative analysis of a specimen containing a target molecule, the opto-electronic device comprising a specimen cell adapted for receiving the specimen and for transporting the band of light, a device for comparing the band of light before entering the specimen with the band of light after exiting the specimen, wherein the target molecule. The device for comparing comprises: an optical sensor; and, a signal processor for determining a quantitative level of the target molecule within the specimen. The signal processor utilizes Bayes' Theorem for determining the quantitative level of the target molecule within the specimen.

Abstract: An antenna assembly for transmitting a radio signal from a radio signal transmitting device includes an antenna unit comprised of a dipole driven antenna member for transmitting a radio signal from the radio signal transmitting device. A radiation reflector reflects the radio signal transmitted by the driven antenna member, and a support member supports the driven antenna member and the radiation reflector so that a predetermined gap is precisely maintained between the driven antenna member and the radiation reflector. A shielding member shields a portion of the radio signal transmitted by the driven antenna member in a direction toward the shielding member. The antenna unit is pivotally mounted so that it is disposable at selectable positions relative to the shielding member. The output of the radio signal transmitted by the driven antenna member can be controlled depending on a position of the antenna unit. The dipole driven antenna member comprises a first and a second segment made from a metal foil.

Abstract: A hand-held radio telephone for communication through an orbiting satellite is provided. An antenna assembly is fixed to the hand-held radio telephone and includes a radiation absorber defining an open curved shape in cross section, so as to define an open transmission area. An antenna is disposed adjacent to the open transmission area so that during use of the hand-held radio telephone some of the radiation signal emitted from the antenna is absorbed by the radiation absorber. The radiation signal that is not absorbed by the radiation absorber is transmitted through the open transmission area for reception by a remote receiver, such as an orbiting satellite. At least one parasitic radiation redirection element receives radiation emitted from the antenna. The radiation received by the parasitic radiation redirection element is directed toward the open transmission area, so as to extend a transmission range of the antenna assembly, and thus extend the transmission range of the hand-held radio telephone.
