  • Publication number: 20080038317
    Abstract: Lacrimal canalicular inserts include a polymeric component and a therapeutic component. The therapeutic component is released from the inserts for extended periods of time, such as for more than about 2 weeks after placement in a lacrimal canaliculus of an individual. The polymeric component may include one or more non-biodegradable polymers, one or more biodegradable polymers, or combinations thereof. The therapeutic component may include one or more therapeutic agents. Therapeutically effective amounts of the therapeutic component are released from the insert and provide sustained drug delivery to the eye and/or the nasolacrimal system of the individual.

  • Publication number: 20070117507
    Abstract: A direct conversion satellite tuner is fully integrated on a common substrate. The integrated tuner receives an RF signal having a plurality of channels and down-converts a selected channel directly to baseband for further processing. The integrated tuner includes on-chip local oscillator generation, tunable baseband filters, and DC Offset cancellation. The integrated tuner can be implemented in a completely differential I/Q configuration for improved electrical performance. The entire direct conversion satellite tuner can be fabricated on a single semiconductor substrate using standard CMOS processing, with minimal off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.

  • Publication number: 20070077908
    Abstract: An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides programable attenuation and a programable gain low noise amplifier. Frequency conversion circuitry advantageously uses LC filters integrated onto the substrate in conjunction with image reject mixers to provide sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on chip. The filters utilize multi track spiral inductors. The filters are tuned using local oscillators to tune a substitute filter, and frequency scaling during filter component values to those of the filter being tuned. In conjunction with filtering, frequency planning provides additional image rejection. The advantageous choice of local oscillator signal generation methods on chip is by PLL out of band local oscillation and by direct synthesis for in band local oscillator.

  • Publication number: 20070031472
    Abstract: Biocompatible intraocular implants include a steroid and an auxiliary agent, where the auxiliary agent is present in an amount sufficient to lessen the severity of at least one side effect compared to the use of an otherwise identical implant lacking said auxiliary agent. The steroid and the auxiliary agent may be present on the same intraocular implant or on different implants. The steroid and auxiliary agent may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the steroid may be associated with a polymeric coating having one or more openings effective to permit the steroid to be released into an external environment. The implants containing the steroid and an auxiliary agent may be placed in an eye to treat one or more ocular conditions while reducing the side effects otherwise accompanying steroid use.
