Wireless Surveillance Camera

MicroPower Technologies (San Diego, CA) has announced the Helios ™ IR Camera. With the addition of an energy-efficient IR illuminator, the Helios day/night device captures and transmits IR-illuminated video data wirelessly up to ½ mile. Powered by solar energy and an internal, long-life lithium battery, the Helios IR Camera yields continuous operation for up to five days on a single charge. The wireless technology does not require cabling for power or data transmission. The system is designed with a smaller footprint — reducing the solar panel size to 1.2 ft2.

Machine Vision Camera

Measuring 23 × 26.5 × 21.5 mm (.9 × 1.04 × .84"), the uEye™ XS from IDS Imaging Development Systems (Woburn, MA) delivers images from distances of 10 cm, either automatically or manually using software. The associated API function also enables the current focus position to be read. Digital zoom allows continuous enlargement of smaller sections of the image. A range of automatic image control functions, including auto white balance, auto gain, and auto exposure time, are performed in the camera itself.

Optimizing Closed-Loop Control in Hydraulic Motion

Performing closed-loop control of hydraulic servo systems is often more challenging than controlling servomotor systems. The main reason is that hydraulic systems use compressible oil to move the actuator. Because of this, a hydraulic system can be modeled as a mass between two springs, where the piston and the load is the mass, and the oil on both sides of the piston represents the two springs. In contrast, servomotor systems are easier to control because there is basically only the inertia of the motor and the connected load to be dealt with.

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.
