DBD Device Offers Transdermal Medicine Delivery

DBD Innovations Iontophoresis is a well-researched technique for delivering medicines and cosmetic agents through the skin. Current techniques, however, are inefficient, and existing devices are often expensive, bulky, and awkward. A Dielectric Barrier Discharge Iontophoresis (DBDI) solution enhances the efficacy of existing remedies by applying a small electronic device to the treated area.

Dispensing Closure Technology Seals and Separates Ingredients

StarOne Group The Drop-Top™, a container closure and delivery system, features an internal, multi-cavity design that stores up to three separate doses of ingredients, including liquids, powders, gases, granules, or tablets. The dispensing closure technology increases the shelf life of products that are not stable in oxygen or aqueous solutions, and stores highly sensitive products that cannot have any contact with the environment or specific ingredients.

Mechanism Allows Pedals to be Used Together or Separately

Current bicycle mechanisms allow only alternate use of pedals, thus halving possible torque. A new arrangement allows simultaneous use of both pedals. The TEJJ cycle uses the force of alternately pushed pedals to start or maintain momentum. When carrying higher loads or climbing a hill, a rider can also optionally push both pedals simultaneously to increase torque. Springs return the pedals to their optimum driving position, and the main driving gear freewheels even as the pedal returns to the driving position. The new mechanism has application for pedal-driven carts of all kinds, and in pedal-driven vehicles for the disabled.

Technology Tests for Unwanted Microorganisms

Clinical and industrial instruments, clothing, gloves, and work surfaces may contain or acquire microorganisms, which flourish or grow as a function of the environment in which they are located. Such growth may lead to the proliferation of toxin- or allergen-producing pathogenic organisms. Using nucleic acids, a new technology provides a more sensitive, convenient, and less costly way to test for the presence of unwanted microorganisms.

Low-Cost Technology Detects Bad Breath

Most individuals experience bad breath (malodor or halitosis) occasionally, but few people can selfdiagnose when it occurs. Proto - types and initial human trial clinical tests have been completed on a low-cost bad-breath detection device. The detector changes color when the user blows through a tube.

Time-Based Tracker Boosts Solar Energy Production

Solar panels are normally positioned at a fixed position. If a panel uses a tracking system to follow the movement of the Sun, however, more solar energy can be collected. Instead of having light sensors that are often disturbed in cloudy environments, a new time-signal-based system uses a programmable logic controller (PLC) to give a start signal at the end of a fixed time.

Zeolite Production Method Removes Soil Pollutants

X-type zeolites use an ion-exchange mechanism to capture and retain heavy metals for soil and water remediation. Zeolites are hydrated aluminosilicate minerals characterized by a three-dimensional open structure. Their cation exchange capacity (CEC), large surface area, and porosity allow the absorption and encapsulation of pollutants. The geopolymer product, containing the zeolites in formation, can be applied directly to contaminated soil, thus immobilizing toxic heavy metals within the zeolite structure during growth and formation.
