least 10 studies in the past 15 years have unanimously denounced ultrasonic devices as having no repellency value whatsoever. Yet, consumers flock in droves to hardware stores to purchase these contraptions. Why? The discovery that mosquitoes locate mates in mating swarms via wing beat frequency generated a great deal of research into ultrasound as a potential source of environmentally-friendly control.

Like the question above regarding plastic owls and other scare devices, these products can work " sometimes" for a short period of time, but hardly ever solve the large-scale problems they are advertised for. They can be somewhat effective in some situations, but largely we believe they are not worth the investment. We've seen pigeons nesting right next to such devices.

Although the ultrasonic algae control devices function the same way (killing algae by breaking it's "rigid" cell wall with under water sound vibrations), they all have a different capacity and range of action. Each algae control device is specially made for a certain field of application.(pond, lake, pool, watergarden, industrial applications, etc.) TOP

Ultrasonic cleaning utilizes the cavitation energy of millions of exploding bubbles created as high frequency sound waves pass through a cleaning solution in specially designed tanks. Simply put, the sound waves create millions of microscopic bubbles which expand and explode in milliseconds. Anything placed in the tank is bombarded and cleaned by this gentle yet thorough "bubble scrubbing" energy.

ultrasonic sound pulse is emitted up to 3 times per second from the base of the transducer. The pulse travels through air, reflects against the process medium below and returns to the transducer. The sensor measures the pulse time of flight between sound generation and receipt, and translated this into distance or liquid level height within the vessel. Click to view ultrasonic white paper.

The Ultrasonic Ranging system uses a 6500 series ranging module and a unique electrostatic transducer as a speaker to generate a short burst of high frequency sound. The sound travels out form the transducer in a narrow cone and reflects back to the transducer from objects in its path. The same transducer then becomes a microphone, used to receive the reflected sound energy and converts it into an electrical signal.

Ultrasonics convert mechanical movement to energy. Ultrasonic bonding uses no heat on the workholder to bond wire to the die and the substrate.

New Zealand’s electrical supply is 230/240 volts, 50 cycles, so 110 volt hairdryers and other U. S. electrical devices will not work without converters. Most hotels provide 110 volts for electric shavers.

A nasal air mask will effectively stop snoring by forcing pressurized air down the wearer's throat. The mask and hose are cumbersome, uncomfortable, and the device requires the wearer to have an electrical outlet at hand. It can also present a problem when travelling. Another device is a simple dental appliance which can significantly reduce snoring and aids in preventing Sleep Apnea when worn to bed at night. It is called an Anti-Snoring Device or ASD.

Until recently, traps worked to collect some specimens and determine which species were present, but didn't control mosquitoes. Now some traps touted as potential mosquito control devices. Some of the mosquito traps now available use carbon dioxide as their principal attractant, and others add octenol or other attractants. Some of these newer traps capture many times the number of mosquitoes as their predecessors, and may help reduce mosquito annoyance.

Changing how a stutterer hears his voice usually improves his fluency. Speculatively, such altered auditory feedback corrects the auditory processing underactivity seen in adult stutterers' brain scans. The altered auditory feedback effect can be produced by speaking in chorus with another person, or hearing one's voice echo in a well. However, this effect is usually produced with electronic devices.

SG-2000 Ultrasonic Home Spa machine comes with a special flexible mat lined with ceramic cells. The processing unit of the machine generates a maximum of 46 litres (per second) of ozone and anion-laden air that is thrust out of the mat via minute holes. This rush of air produces millions of very very small high-energy bubbles. Continuous collision generates ultrasound with a frequency of 8-10 kHz of high frequency energy which is converted into other forms of energy.

The Lucidity Institute's lucid dream induction devices are designed to help people achieve lucidity by giving them cues while they are dreaming and also by providing a reliable means of testing one's state of consciousness. They do not make people have lucid dreams any more than exercise machines make people develop strong muscles. In both cases the goal, strength or lucid dreams, results from practice. The machines accelerate the process.

XL Pro 6 and XL Pro 7 support UMPC's (Ultra Mobile Personal Computers) but we do not support Pocket PC's. We stopped supporting Pocket PC's and other hand held devices several years ago. Surveys indicate that most inspectors who use a hand held or Pocket PC later switch to a larger format after a very short time (usually within six months) because the display screens and are too small to be practical and data entry is very time consuming.

All models consist of 2 main components, a GPS antenna and a cellular modem. The GPS antenna receives the coordinates of several satellites orbiting the earth and also the distance to each satellite. The GPS antenna then applies a triangulation algorithm on this data to calculate its own position. The vehicle location device's latitude and longitude data is then forwarded to the GPS Solution's Datacenter by the cellular modem where it can be queried and utilized for tracking purposes.

It should, because there is really no difference from backup Software point of view if a drive is local or NAS. We have some customers backing up to NAS disk storage. Anyway if you are planning backup with Stratesave and NAS storage, it should be tested first the particular NAS storage and Stratesave.

They will work with any audio device (CD player, MP3, radar detector, etc.) that has a standard 1/8" output jack. An adapter can be used if your device has a 3/32" jack.

The Mix-It has been used with numerous devices, really too many to list. The most popular items, and those I have used personally include: Apple iPod, Lyra MP3 player, Personal Music Jukebox, iRiver CD player, Sony cassette walkman, Sangean AM/FM radio, Valentine 1 radar detector, Escort Passport radar detector, Garmin StreetPilot III, Garmin 2610 GPS, etc.
