LifeGuard™ – Model 1
The DKL LifeGuard™ has proven itself in the field. At the invitation of the City of New York, DKL, along with the National Guard, provided around the clock LifeGuard™ search teams at the World Trade Center for the first 10 days. The search teams detected and were able to find numerous missing or unidentified rescue workers, as well as locating one survivor. In a recent nationwide disaster relief drill in Japan, LifeGuard™ detected survivors in a collapsed building faster and more effectively than any other technology or search technique. The Taipei City (Taiwan) Fire and Rescue Team brought its DKL LifeGuard™ equipment to earthquake-stricken El Salvador and successfully used the equipment during this mission.
The current applications of the LifeGuard™ include:

• Military – Can be utilized to reduce or eliminate the element of surprise in an outdoor area, in buildings and caves, and be uniquely effective in most search and rescue missions

• Law Enforcement Scanning buildings, vehicles or other areas where direct observation of the presence of human beings is prevented or dangerous

• Search and Rescue Scanning isolated or heavily wooded areas for missing persons or military personnel, scanning avalanches, earthquakes and collapsed buildings for trapped persons, scanning buildings on fire to speed rescue by emergency personnel

• Security - Scanning an area to ensure the security of a facility or area. Checking trucks or other vehicles for stowaways

Competitive advantages include the following:

• Effectiveness of product is not dependent on visual contact

• May be used with or without computer

• Small-size (hand-held)

• Not dependent on environmental conditions

• Detection not interfered/influenced by animals

• Detects only humans

• Takes 30 to 40 seconds to scan an area for the presence of a human

• Moderate cost

• Safe to operate

LifeGuard™ - Model 25
The Company has completed hand-built, proof of concept prototypes of Model 25 that demonstrate key proprietary technological advantages. These prototypes are smaller and more efficient and are targeted for mass-market sales into the security market. This new generation LifeGuard™ is designed to allow the user to detect a human at short range and require almost no training. The specific improvements are as follows:

At the conclusion of the development program, the second generation LifeGuard™ will satisfy the following objectives:

• Range of 20-50 meters through a 1-meter thick concrete wall

• 80% reduction in training time

• Improved detection through various barriers

• Packaged to satisfy drop test, watertight tests, etc.

• Reduced battery weight and size

• Digital read out of detection information

SilentGuard™
SilentGuard™ is the second product under development utilizing DKL’s patented technology.Currently a  prototype it is ready for licensing and further development. While the LifeGuard™ is handheld, the SilentGuard™ is an autonomous sensor that can detect:

• The presence of a human at short and mid ranges through walls and doors

• Respiratory and heart rate at short range

Applications include:

• Security and military - enable detection of a human being in the home, business or any environment. It responds like a human specific motion detector and is being developed to enhance security alarm systems.

• Medical applications include sensors developed to monitor the human respiratory system and heart rate at any medical facility, home, and/or work environment

The initial version of SilentGuard™ is a module that could be incorporated into existing, installed security systems or operating as its own stand-alone security system. This version is suitable to demonstrate to customers or potential licensees.

Plastic Detection System (PDS)
DKL has demonstrated the ability to build a sensor that can detect a piece of plastic buried ten inches in the ground from a distance of 15 meters. These sensors can also discriminate among different types of plastic. The PDS is close to being able to detect plastic piping underground for the industrial market.

The PDS is similar in operation to the current LifeGuard™ model. It is:

• Passive

• Hand-held

• Horizontal line-of-bearing

• Range is estimated to be 5 to 15 meters

• PDS will detect a specific plastic materials

Future Products and Services
DKL's principle advantage is that it is the first to market an easy to use portable instrument capable of reliably detecting human targets, and only human targets, through barriers. DKL's R&D division is actively expanding its knowledge of this new technology so that in the future, DKL’s products will not only be able to detect a field generated by a human being, but it is expected to also measure and map that field to allow for the specific identification of each living human being. Such advances may enable DKL to create new industries.

DKL intends to develop products in the following industries during the next three years:

Security: DKL’s technology can be integrated with other devices already in use in the security industry, specifically for border protection and control, property protection, perimeter security, elder care home monitoring, and hostage rescue.

Biometrics: This technology can be integrated in products that allow keyless operations of doors, cars and can be used with equipment to allow specific access to machinery and computers.

Medical Science: Management believes that DKL's technology will have important applications in the medical world, specifically in the non-invasive monitoring of vital signs such as heart and respiration rates and readings similar to electro-cardiograms (ECG). Physicians currently measure all of these readings at the skin's surface. The new technology will allow doctors to take readings without attaching sensors to the patient, and may be integrated with existing medical devices.

Automotive: The deployment of airbags in cars has resulted in deaths and injuries. We believe that DKL's technology will allow the manufacturers of airbags and associated technology to determine whether a human is in a seat in order to adjust the speed and force of an airbag to the occupant of that specific seat.

Enhancing Existing Technology: This unique identification and detection technology could be used in the development of interactive capabilities within technology devices. There are a number of products that could utilize the technology for recognizing humans and eventually the individual signature of any human. These could include user identification for automobiles, computers or digital information and entertainment devices, televisions, radios, game devices, robots or dolls that recognize humans within a set distance and can turn on, greet, play and shut down all based on the identity and proximity of a person.

Animal Registry/Identification: DKL believes that it can develop locators for tracking additional species, such as endangered animals, livestock, domestic animals, etc.
