Industry View -- Exclusive to Electronic Design UPDATE ********************** Did You Write It Down? How To Correctly Keep A Notebook For Your Ideas Brad Thomas, ip help llc Engineers must know not only how to come up with inventive ideas, but also how to protect them. A key factor in that protection is a properly maintained notebook. This can help you prove that you are the inventor as well as when you thought of the idea and turned it into an actual object or process. It also can prove that you did not abandon the idea while you developed it and that it was new and original. All of these factors are important in defending and protecting your rights. Here are some suggestions on keeping a notebook: * Use a book with permanently bound pages. * Write your name, address, and the date you began to keep the book on the front cover. * Number the pages. * Use signature lines at the bottom for your witnesses. For example, write "Witnessed and Understood:" with a "Signature" line and a "Date" line. * Write all entries in ink and by hand. * Do not erase. Cross out errors, and make a new entry. Entries should not be changed at a later date. Make a new entry, cross-reference the earlier entry, and point out any change. * Make entries as you work. * Date every entry. If you're writing about something that happened before, state when the work was actually done and why you did not enter it earlier. * Record dates of conception and dates of "reduction to practice." A sketch and brief description may be enough to establish conception. You need to make and successfully test the invention to show reduction to practice. * Write so that you could prove facts in court. Be candid. Be credible. * Write so that a coworker could continue from where you stop. * Avoid making negative notes such as "Does not work," which might be interpreted as you abandoning the idea. * Indicate which project your work involves. * Include all plans, procedures, diagrams, and sketches considered during the project, along with information to identify and explain the subject matter. The entries should indicate the nature of the project, when it started, ideas considered, what was made, what was tested, test results, observations, and conclusions. * Sign and date pages when full. * Do not leave blank areas on a page. If you want a separation, draw a diagonal line or cross through the open space. * Have at least one impartial person who is competent to understand the work regularly examine, sign, and date each page. This person should not be a spouse, best friend, joint inventor, your patent attorney, or a notary public. Find a witness who can be trusted to keep your work confidential and who will be available later in case you should need testimony to support your claims. * Record the names of people involved with the work. * Record the names of witnesses present during demonstrations and important experiments. Have at least two sign your entry. * Record the name of the invention. Include its purpose and a description. Also include a working sketch/diagram and describe similar publicly known inventions/prior art, novel features, and its advantages and disadvantages. * Record how you developed your idea. Include the progress and completion of compounds, assemblies, or models that are being prepared for testing. Explain how these are being made. * Record how you tested your idea, the results, and what you learned. Make particular note of successful tests, including dates, the elements involved, and comments on the results. * Write objectively, and focus on the facts. Do not write conclusions unless they are supported by the facts recorded. * Permanently attach all important loose documents, such as letters, sketches, photos, or printouts relevant to the project in the notebook with your signature and date. Include a reference to attachments in your entries. * File receipts, correspondence, cancelled checks, and other miscellaneous documents relating to your invention. Note the date you received them. * Ensure that your work and notebook contents are kept secret. Consider confidentiality agreements for your witnesses. Add the line "The above information is confidential" just above your witness-signature area. * Lock up your notebook. All this detail may seem tedious and time consuming. But if you ever have to prove the ownership of your work, it will be invaluable. Brad Thomas is the founder and president of ip help llc, Deerfield, Ill.

Focus On Test & Measurement ********************** ***Vibration Analyzer Is Fully Programmable A full-featured vibration analyzer, the ZonicBook/618E offers eight to 56 channels of data acquisition. Its PowerPC-based Ethernet engine transfers acquired data to the host PC at better than 2 Mbytes/s. The dynamic inputs are software programmable for voltage range (nine ranges), ac/dc coupling, and ICP source, and they read sensor calibration information. Software in the PC determines all of the analyzer's capabilities, so users can upgrade their units as needed. Five software packages are available, each tailored to a particular vibration measurement and analysis application. The hardware portion of the system is the signal conditioning and acquisition engine. The eight-channel ZonicBook/618E with one eZ-Series software package costs $13,999. Each additional eight-channel option is $4899. Delivery is in three weeks. IOtech Inc. ==> http://lists.planetee.com/cgi-bin3/DM/y/eA0Gl4E70Fh10BHtk0AB ********************** 3. News -- From The Editors ********************** ***2.4-GHz Antennas Offer High Gain The Model PA24 2.4-GHz directional, high-gain antennas come in thin, low-profile packages. The PA24-13 (13.0-dBi gain) and the PA24-19 (19.0-dBi gain) are designed for use with wireless local-area networks and IEEE 802.11b/g applications. They operate from 2400 to 2485 MHz, with a temperature range of -40 deg. C to 70 deg. C. They have a Type N female connector. The weatherproof antennas are made of gray UV-resistant ABS plastic radomes with aluminum backplates and die-cast aluminum brackets that can tilt 45 deg. Mounting hardware is stainless steel. The PA24-13 is 7.5 by 7.5 by 0.8 in. and weighs 17.6 oz. The PA24-19 is 15.4 by 10.6 by 0.8 in. and weighs 60 oz. The PA24-13 starts at $39.95, and the PA24-19 at $64.95 (1-9). In 100-piece quantities, the antennas cost $33.96 and $55.21 each, respectively. The are available from stock. Pacific Wireless ==> http://lists.planetee.com/cgi-bin3/DM/y/eA0Gl4E70Fh10BHtl0AC ***Magnetoresistive Device Accurately Measures Position, Current Using two magnetic field sensors, the ZMX40M accurately measures linear position and high-voltage current with a sensitivity greater than that of traditional Hall effect devices. Thin-film permalloy stripes covering each sensor form a Wheatstone bridge that provides an output voltage proportional to the magnetic field (Hy) running the length of the SM8 package. Internal permanent magnets create a perpendicular field (Hx) that suppresses hysteresis and biases the sensors in their linear region. With calibration to allow for tolerance differences between the sensor bridge outputs, the ZMX40M can resolve distances down to 30 microns in toothed-wheel and automotive applications. By combining both bridge outputs and locating an external current loop above or below the ZMX40M, a high-voltage current sensor can be created. The device costs $1.95 each in lots of 10,000. Delivery is four to six weeks. Zetex Inc. ==> http://lists.planetee.com/cgi-bin3/DM/y/eA0Gl4E70Fh10BHtm0AD ***70-W, 1U Supplies Feature Active Power-Factor Correction The REL70 series of high-density enclosed switching power supplies delivers outputs of 70 W while meeting the space and performance needs of 1U packaging. Twenty-two models are available for single, dual, triple, and quad outputs from 2.5 to 48 V dc. All accept 85 to 264 V ac, offer active power-factor correction to 0.98, and have soft-start circuitry and integral electromagnetic-interference filtering that meets EN61000 requirements. They include a power-good LED indicator and an output-adjustment potentiometer. Operating ambient temperature range is -10 deg. C to 50 deg. C without derating. Measuring 4.5 by 2.5 by 1.22 in., the supplies come with Molex-style connections. They cost $69 each in units of 100 and are available four weeks ARO.
