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.

Additives to Minimize Dirt Accumulation

Polymeric and non-polymeric additives must release dirt from stucco, decks, and other coated architectural surfaces. A client seeks hydrophobic surfaces that are hard rather than tacky, and offer low surface tension and high contact angle. Preferably, a homeowner could spray these enhanced coatings with water and quickly wash away accumulated dirt. The additives must be compatible with water-based systems such as acrylics and styrene-acrylics or alkyds, as well as with polyurethanes and epoxies. Technology options must also accept occasional re-coating, and resist standard soaps and household cleaners.

Cost-Effective Cholesterol Tests

A client seeks a simple, small, and cost-effective diagnostic cholesterol test kit. The technology must be used directly by a consumer, possibly as an in-home test kit. Results should be visible immediately and show different levels, including normal, moderately elevated, or high cholesterol. Solutions could be minimally or non-invasive diagnostics that detect one or multiple states, and could include tests for blood, breath, saliva, sweat, urine, or tongue scraping. Ideally, tests must be validated against standard blood cholesterol tests, and detect a 10% change in total cholesterol.

New Systemic Chemical Insecticides

A client seeks new synthetic (chemical-based) control agents for insects such as aphids and spider mites. The piercing and sucking insects damage plants by inserting their mouthpart into plant tissues and feeding on the juices. Heavily infested plants become yellow, wilted, deformed, or stunted, and may eventually die. There is a need to pursue insect control agents with new modes of action in order to keep insecticide resistance at manageable levels. The proposed insect control agents must be systemic, broad-spectrum insecticides that have low risk to humans and the environment.

Natural Food Actives for Positive Mood Enhancement

The overall consumer experience of foods is impacted by various sensory factors including taste, texture, and smell, as well as by ingredients that occur naturally in various foods, which can directly impact one’s mood. Food additives also affect various mood neuro-actives, such as serotonin, adenosine, endorphins, and oxytocin, either through increasing their biosynthesis or by modulating their receptors. A company seeks cost-effective food actives that enhance positive moods in consumers. The technology must be derived from natural sources and be safe for human consumption.

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.
