Inventor’s Corner:  A wireless test indicator from Dave Hoffman of Hagenhoff LLC
Wireless test indicator measures blind holes

Our new column Inventor’s Corner showcases inventions that engineers have cooked-up in their spare time.


The wireless test indicator is designed to help toolmakers and lab technicians make accurate remote measurements. The idea comes from Dave Hoffman of Hagenhoff LLC, Canton, Ohio. The patented “Vyndicator” consists of two pieces, a stylus (sensor) and a receiver (display). The invention works something like a dial indicator but it is far more versatile because of the detached stylus. The device has a measurement range of 0.200 in. — five times that of a normal test indicator — and a transmission range of 30 ft.

The stylus unit (transmitter) contains a microprocessor that is connected to a linear sensor. The transmitter sends signals in packets to the receiver. The display unit (receiver) uses a second microprocessor that captures and decodes the signals. Signal packets contain data that describe the movement of the stylus. The receiver microprocessor decodes and displays the movement on an organic LED (OLED) display. Besides a digital readout, the display features a horizontal bar that expands and contracts to represent the movement and amount travel of the stylus.


The wireless test indicator can reduce the amount of time spent in tasks such as centering a part on a milling machine. In addition, the device can serve in areas where it is dangerous for personnel to make measurements. The indicator also lets users take readings in locations where a traditional dial indicator would not be visible, as in a bore.

Before the invention, machinists often had to use creative methods to get a dial indicator to the location to be measured, especially in blind areas or places where a dial indicator is rotated out of view. Hoffman says he got the idea while watching a machinist do involved and time-consuming measurements using a standard test indicator (a tiny dial indicator). “The thought popped into my mind that there should be an easier way to make these measurements,” he says.Parker Hannifin, Babcock & Wilcox, JJB Engineering, Ansco CNC Specialists, Cornwell Tools and Standard Engineering Group, all of the Akron, Ohio, area, SchoellerBleckmann Energy Services, Grayledge Pump & Industrial LLC, Logan Machine Company and GM Lordstown, Ohio, are currently using the wireless test indicator.© 2010 Penton Media, Inc.

MyTee Golf Products

Successful Inventor Rocks the Marketing and the Golf World!

By Andrew R. Spriegel

December 13, 2009

Here is a brand new golf tee that adds additional distance to you drive!  Why, it has less mass and therefore there is less resistance than a golf tee when driving a golf ball.  As you can see the tees are die stamped into a Teslan Business Card!  That’s right a business card, talk about building you brand.    Note: The Stealth Tee Conforms with the USGA Rules of Golf.

Car dealers that have reported that when the person given the card runs out of tees (5 tees last about two full rounds of golf) they come back to the dealer for more cards!  What a great way to sell a car.

So you thought you knew everything about a golf tee and then along came Rich Spencer!

No harmful toxins are produced during the production of the Teslin cards, unlike their petroleum based counterparts. Teslin cards are printed with superior color consistency and are less susceptible to breakage and snapping due to their ductile/elastic properties. Some additional environmental features include: Non-toxicity, no ozone depleting constituents, no cellulose-based material (no forest harvesting), incinerates in an atmosphere of excess oxygen to yield water, carbon dioxide, energy and clean ash (from silica filler).

Frank Fleischer, 80 Years Young this Year and Still Inventing!

Interview with Frank Fleischer

February 28, 2010

Interviewer: What are you up to these days, at almost 80 years young you must be kicking back and relaxing?
Frank: Hardly, I currently am the president of the Canton Inventor’s Association which I founded about 15 years ago.  I recently invented a health care product to help realign people’s hips while sleeping.  The product is being brought to market and is selling for example in nursing homes, drug stores, chiropractic offices, doctor’s offices, and other locations.  At 79, I am sure that I am one of the “oldest new start-up” businesses in the country.

Interviewer: What is the patent pending product called?
Frank: “Nee-Z-eeZtm” which stands for “Knees Ease”.

Interviewer: How does the “Nee-Z-eeZtm” work?
Frank: Well unlike a pillow that moves when a person sleeps, the “Nee-Z-eeZtm” always rests properly in place because of the adjustable strap. We received an endorsement from a woman the other day that said with the “Nee-Z-eeZtm” she slept through the night for the first time in years.  She has tremendous hip pain and she always slept with a pillow between her legs.  When the pillow shifted during sleep she was always awakened by the pain.  With the “Nee-Z-eeZtm” the device didn’t shift so she is now able to sleep through the night.

Interviewer: What has been different in the case of this invention?
Frank: My partner Andrew Spriegel has a lot of experience in commercializing products.  He has helped out quite a bit in the process.  In addition, he owns his own law firm, Spriegel & Associates, LLC ( Patent & Trademark Attorneys.
