Poly-Pak® Purification Cartridges

A filter type packed HPLC column assembly used for the rapid and efficient purification of synthetic oligonucleotides.  A four-piece assembly consisting of two injection molded case parts with two micro-porous frit elements.  Active filtering media is 20-micron average particle size, hence all fits are extremely critical in order to contain the 20-micron powdered media.  Filter assembly with one male and one female luer for use as a syringe end or vacuum manifold purification system.  Injection molded case assembly utilizes an annular snap ring method of assembly.

Omni-Jugs® Contaminated Fluid Collection System

A 15-liter vacuum assisted collection container system for use in the operating room.  Product had to be simple and easy to use yet completely sealed to prevent spillage and vacuum leaks.  Three injection molded parts, with integral closures are used to make this collection system complete for any OR procedure which produces large amounts of contaminated fluid waste.  Special arrangements of the fittings allow for cascading to additional containers and for the collection of tissue specimens when using the optional Specimen-Cap®.  U.S. Patent #5,792,126 protects this product.

Universal Transmitter

Rescue project.  This product enclosure was designed by a West Coast design build firm, who had bid on and received an order for the production tooling.  Only after receiving the order, did they inform the client that they could not make the tooling and parts as they had earlier indicated.  The client was stuck and needed help.  We were asked to look at the designs and to help find sources for the production tooling, all to be completed within 4 calendar weeks.  The upshot was that the case could not be molded as it was designed.  The undercut specified for the case closure was 5 times to large for the material as specified by the client.  We redesigned the enclosure, keeping the original style and exterior look and feel, produced complete working prints and files, found a quality molding and tooling source, coordinated the tooling effort and provided complete samples in the requested materials and colors within the 4 week window.

Sprayer / Applicator system for Noah® Deck & Fence Renewal System

Dual bottle and sprayer development program for diluting two different concentrates at two different ratios with two different flow rates.  Extremely tight dilution ration ranges for applying the deck cleaner and the water-soluble deck stain product.  Designed twin blow molded bottle set with features to mate with injection molded seal component as nested within the injection molded bottle closure as attached to the sprayer assembly.  Work with all vendors involved debugging delivery system.  ¼ Pallet display earned awards at the 1999 National Hardware Show.  Several U. S. and foriegn Patents applied for, to protect technologies used in this product.

50 watt Halogen Back-Up Bulb

Component design of one injection molded high temperature insulator and two contact stampings for a pressure contact assembly.  Utilizes 50 watt halogen bulb and standard 1156 style bulb base, with only one solder operation per assembly.  This design resulted in a 46% savings in assembly labor costs.

Christiana Candles® Exterior Decorative Window Candles

Developed 4-piece injection molded part assembly with two identical progressive die stampings.  Utilized off the shelf socket component and developed this easy to install novel decorative candle program.  U.S. Patent #5,829,869 protects this product.

RF Thermometer

Remote waterproof temperature sensor/transmitter enclosure and indoor receiver unit with display and controls define the system.  Remote transmitter/sensor unit consists of two injection molded case parts, which are assembled via friction fit with an o-ring seal and frit breather element.  Float accessory accepts remote transmitter/sensor and allows use in ponds and pools.  Receiver unit has dual read-out LCD display showing both indoor temperature and remote temperature.  Liquid silicone keypad controls allow user to set min/max alarms for both indoor and remote temperatures, as well as track min/max history with reset capabilities.  Our receiver case design has a user accessible battery door, a molded in keyslot that allows for wall mounting and comes with an integral desk stand.

Truck Tire Mounted RF Pressure Sensor

Differential pressure sensing device designed for use in heavy over the road trucking applications.  Sensor is strapped to the inside of the truck tire rim and contains in & out valves along with radio circuitry, battery means and the differential pressure switch.  The system is patented worldwide.  Differential cracking pressures for the in valve and out valve allow the sensor to be set, yielding a 2 PSI differential between the interior of the sensor device and the tire atmosphere.  As the tire pressure drops the sensor device pressure remains constant.  Switch is actuated when tire pressure has dropped 5-6 PSI below sensor interior pressure.  Once switch is actuated, battery power is supplied to radio and repeating code is sent to cab receiver indicating a low-pressure condition.

Clear Surface Mount Snow Guard

Needle Guard® Single –Use Sharps Containment System

Single handed encapsulation of contaminated syringe or scalpel, via injection molded plastic sheath filled with a fluid, covered with a breakable membrane seal, which upon penetration by the syringe or scalpel would become a solid within seconds.  Research was done under SBIR grant and patents have been issued to protect the product.

Genie Cup II® On-Site Substance Abuse Test Kit

Multiple part injection molded plastic urine container with special lid actuated dispensing feature.  Patient fills cup with sample and installs lid to first mechanical stop as directed by nurse.  Nurse then checks temperature indicator for presence of valid sample and then turns lid another two turns until second mechanical stop.  During this two-turn step, the internal dispenser delivers a metered shot of the sample to the test chamber and seals and isolates the remaining initial sample.  This allows for a rapid on-site test with results and a sealed non-contaminated specimen, which can then be frozen and sent to a lab for redundant analysis.
