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.

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.

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.

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.

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.

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.

Insect Processing Technologies for Chicken Feed

The growing scarcity of resources to produce increasingly demanded ingredients, such as soybean meal and animal protein meals, has doubled feed costs in the recent years. Thus, alternative protein sources, including insects, are urgently needed. Insects must be introduced in the feed chain, and multiple quality parameters need to be taken into account: quality, availability, and cost. Expectations for new technologies include a processing method for the insect, nutritional evaluation, identification of microbiological problems, and financial evaluation to understand the viability of the business.

New Synthetic Nematicides

Nematodes are among the most damaging crop pests. Very few available chemical nematicides can affect control, and some options are restricted by the Environmental Protection Agency and similar bodies. Nematodes damage plant roots, and reduce the plant’s ability to take up water and nutrients. The need is great to discover less toxic, and more environmentally acceptable, chemical substitutes for the current suite of commercial nematicides. Successful technologies must demonstrate efficacy against nematodes or nematode damage to plants, provide at least benchtop data to support efficacy claims, and display new and/or multiple modes of action.

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.
