    摘要: In a particular embodiment, an air purifier assembly is disclosed and can include a housing assembly. The air purifier assembly can include a first fluid communication channel within the housing assembly. The first fluid communication channel can have an air inlet formed in a back of the housing assembly and an air outlet formed in a first side of the housing assembly. Further, the air purifier assembly can include a second fluid communication channel within the housing assembly. The second fluid communication channel can have an air inlet formed in a back of the housing assembly and an air outlet formed in a second side of the housing assembly, opposite the first side of the housing.

    摘要: A method and apparatus for high fidelity duplexing, local transmission and reception of audio-signals transmitted from sources such as stereos, televisions, or musical instruments is taught. According to these teachings, high fidelity wireless stereophonic transmission system having a plurality of audio channels are realized. An oscillator is electrically connected to the first audio channel to provide a first carrier frequency upon which the data of the first audio channel is imposed. The first carrier frequency is then combined with a second audio channel's data forming a composite signal. The composite signal is then imposed on signal generated by a second oscillator. This second oscillator provides a carrier frequency for a frequency modulated (FM) transmitter. The signal from the FM transmitter is received by a receiver and the respective signal's of the two audio channels are demodulated and used to drive speakers.

    摘要: The present invention relates generally to a mixture of coated and non-coated sulfonic acid cation exchange resins (Amberlite IR69) cross-linked with about 8% divinyl benzene onto which dextromethorphan has been loaded. About 30% of the drug/resin complexes are coated with a mixture of ethyl cellulose or ethyl cellulose latexes with plasticizers and water dispersible polymers such as SURELEASE. The coating level is about 50% w/w drug. Coated and uncoated drug/resin complexes are loaded with drug to about 45% by weight drug/resin complex. The ratio of coated and uncoated drug/resin complexes is about 55/45. The particle sizes of the coated and uncoated drug/resin complexes is about 20 to about 300 and about 20 to about 250 microns, respectively.
