  • Patent number: 11285307
    Abstract: Wireless and non-wireless drug delivery integrated circuits, systems, and methods of delivering therapeutic pharmaceutical compounds are provided. The system can include a control module, a wireless drug delivery integrated circuit, a first electrode and a second electrode that are both attached to the wireless drug delivery integrated circuit, an electroactive polymer, and a pharmaceutical compound. The electroactive polymer and the pharmaceutical compound can be formed as films on one of the electrodes and, when placed in a solution, a voltage potential can be applied across the electrodes causing the pharmaceutical compound to be released into the solution.
    Type: Grant
    Filed: February 17, 2017
    Date of Patent: March 29, 2022
    Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INCORPORATED

  • Patent number: 10588306
    Abstract: Embodiments relate to smart mosquito and insect trap devices, networks and method for detecting, counting, trapping and discarding a population of mosquitoes and/or insects. The mosquito species include the ones such as Aedes mosquito species that can cause Zika virus diseases. The device comprising a housing (201) having a directional force through a narrow path (240) to move an insect or mosquito in a predetermined direction. The device comprises one or more detectors (255) to detect a presence of an insect or mosquito along the path (240). An isolated basket (260) or trap is included to trap the insect or mosquito at a location below or at an end of the path. A processor (352) tracks a count of a population in the basket based on detection of the presence of the insect or mosquito.

  • Patent number: 8704575
    Abstract: Active directional couplers are provided. In accordance with certain embodiments of the invention, the subject active directional couplers are tunable. The tuning is accomplished via varactors connected to the lines of the active directional couplers. Active directional elements are provided between different lines of the subject active directional couplers to control a signal path between ports of the different lines. The active directional elements are selected from diodes, transistors, inverting amplifiers, non-inverting amplifiers, differential amplifiers, and active baluns. The lines include a phase shift element between the two ports of each line. The phase shift element is selected from a transmission line, a delay line, and a phase shifter. Advantageously, the subject lines do not have to be designed for ideal phase shifting and can be designed at near 90° or near ?/4 values.

  • Patent number: 7941119
    Abstract: An apparatus and method for processing a digital broadcast signal are provided. The method includes cutting off a noise frequency of a received digital broadcast signal and low-noise amplifying the noise cut-off signal, limiting an amplitude of the low-noise amplified signal spectrum to an amplitude of the digital broadcast signal spectrum, and cutting off a noise frequency of the amplitude limited signal spectrum and passing only a signal corresponding to a frequency band of the digital broadcast signal.
