Title: Image rejection sub-harmonic frequency converter realized in microstrip, particularly adapted to be used in mobile communication equipments
Inventor: POLITI MARCO
IPC: H03D9/06
Filed: 1998-09-14
Granted: 2005-03-22
Abstract: It is described an image rejection, sub-harmonic frequency converter, realized in microstrip, particularly adapted to be used in mobile communication equipment. The converter avails of two identical sub-harmonic mixers employing each one or two pairs of diodes in antiparallel, obtained on a same silica substrate, and of a structure of hybrids performing appropriate phase combination adapted to suppress the image band in the converted signal. The mixers include filtering structures preferably consisting, but no limited to the same, of stubs .lambda./4 long, at the local oscillator frequency, having a free end, in short or open circuit, respectively. According to an alternative embodiment, said stubs are replaced by appropriate filter, implemented with concentrated structures (L and C) performing the same transfer function of the stubs in microstrip. The sub-harmonic converter and a traditional converter can be jointly employed in a terminal mobile equipment operating in "Dual Mode service hand-held" (GSM 900 and DCS 1800) sharing a unique 900 MHz local oscillator.

Abstract: The invention is a quantitative method for measuring the consump tion of a substrate in a microbially catalysed reaction. It involves the incubating of the sample substrate with an excess of a microorganism and an excess of a co-substrate until the substrate has been oxidised to a predetermined end point, and measuring the quantity of reduction of a co-substrate. The method can be used for the rapid determination of the BOD or the biological toxicity of the sample substrate.

Abstract: A sender creates a voicemail message that includes a plurality of messaging elements that include embedded instructions that define a structure of the message. Other messaging elements may include textual fragments, audio fragments that refer to audio data files that are associated with the message, and/or references to textual fragments and/or audio fragments that are stored at specified locations. The instructions may define a hierarchical menu structure which, when the message is presented to the recipient by a messaging system, offers the recipient different navigational choices from which the recipient may select and thus effect the information content of what is presented. The structured message is sent by the sender to the recipient at an address on a messaging system that stores the message and is capable of interpreting and assembling the messaging elements in accordance with the embedded instruction and playing-out the message to the recipient when the recipient accesses the system and retrieves the message from storage. The structured message may also include links to a specific destination, to which the messaging system establishes a connection if the link is selected by the recipient during play-out of the message. Further, the messaging system can gather information from the recipient during play-out and forward that information to a specified destination, which may respond with another structured message. In the described embodiment, a phone markup language is used to define the structure and the inherent embedded instructions associated with the structure of the message.
