This Agreement may not be amended except in writing signed by an authorized representative of each of the parties hereto. Licensee agrees that it has received a copy of the Content, including Software i. Licensee shall not distribute externally or disclose to any Customer or to any third party any reports or statements that directly compare the speed, functionality or other performance results or characteristics of the Software with any similar third party products without the express prior written consent of ON Semiconductor in each instance; provided, however, that Licensee may disclose such reports or statements to Licensee’s consultants i that have a need to have access to such reports or statements for purposes of the license grant of this Agreement, and ii that have entered into a written confidentiality agreement with Licensee no less restrictive than that certain NDA.

The QRD line sensor reflectance sensor is easy to use.

The parties hereto are for all purposes of this Agreement independent contractors, and neither shall hold itself out as having any authority to act as an agent or qr1114 of the other party, or in any way bind or commit the other party to any obligations.

Upon the effective date of termination of this Agreement, all licenses granted to Licensee hereunder shall terminate and Licensee shall cease all use, copying, modification and distribution of the Content and shall promptly either destroy or return to ON Semiconductor all copies of the Qrd114 in Licensee’s possession or under Licensee’s control.

The photodarlington responds to radiation emitted from the diode only when a reflective object or surface is in the field of view of the detector. Using paper with black marker pen, using black electrical tape, using the orange plastic of the Tamiya gears on GRAB-E, etc, with varying results. We will need to dig some information out of it: You post was clear and well written.

Sorry to ring an old post, but this was very helpful. Your request has been submitted for approval. Notwithstanding any terms to the contrary in any non-disclosure agreements between the Parties, Licensee shall treat this Agreement and the Content as ON Semiconductor’s “Confidential Information” including: I may try some of the variations on the resistor values that Rudolf tried. Thanks for tip, Tele! BOM, Gerber, user manual, schematic, test procedures, etc. Fortunately positive lead of each part is longer than negative, so, unless they have been cut, one only need to distinguish between emitter transparent lens and sensor darkened lens.

Any provision of this Qfd1114 which is held to be invalid or unenforceable by a court in wrd1114 jurisdiction shall, as to such jurisdiction, be severed from this Agreement and ineffective to the extent of such invalidity or unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

Out will go to ADC srd1114 of microcontroller. Licensee agrees that it shall maintain accurate and complete records relating to its activities under Section 2. Licensee is and shall be solely responsible and liable for any Modifications and for any Licensee Products, and for testing the Software, Modifications and Licensee Products, and for testing and implementation of the functionality of the Software and Modifications with the Licensee Products.

Except as expressly permitted in this Agreement, Licensee shall not use, modify, copy or distribute the Content or Modifications.

However, during the term of this Agreement ON Semiconductor may from time-to-time in its sole discretion provide such Support to Licensee, and provision of same shall not create nor impose any future obligation on ON Semiconductor to provide any such Support. Such license agreement may be a “break-the-seal” or “click-to-accept” license agreement. Placement of the QRD seems key.

QRD1114 Reflective Object Sensor

It is expressly understood that all Confidential Information transferred hereunder, and all copies, modifications, and derivatives thereof, will remain the property of ON Semiconductor, and the Licensee is authorized to use those materials only in accordance with the terms and conditions of this Agreement. Nothing in this Agreement shall be construed as creating a joint venture, agency, partnership, trust or other similar association of any kind between the parties hereto.


Please allow business days for a response. Neither this Agreement, nor any of the rights or obligations herein, may be assigned or transferred by Licensee without the express prior written consent of ON Semiconductor, and any attempt qqrd1114 do so in violation of the foregoing shall be null and void.

Fortunately positive lead of Fortunately positive lead of each part is longer than negative, so, unless they have been cut, one only need to distinguish between emitter transparent lens and sensor darkened lens. All reports, documents, materials and other information collected or prepared during an audit shall be deemed to be the confidential information of Licensee “Licensee Confidential Information”and ON Semiconductor shall protect the confidentiality of all Licensee Confidential Information; provided that, such Licensee Confidential Information shall not be disclosed to any third parties with the sole exception of the independent third party auditor approved by Licensee in writing, and qd1114 permitted use shall be restricted to the purposes of the audit rights described in this Section I may be getting too much reflected IR.

Few days ago one of our new members asked for help with QRD Refer to drawing and datasheet! At a minimum such license agreement shall safeguard ON Semiconductor’s ownership rights to the Software. Failure by either party qfd1114 to enforce any term of this Agreement shall not be held a qrd11144 of such term nor prevent enforcement of such term thereafter, unless and to the extent expressly set forth qrd111 a writing signed by the party charged with such waiver.

We will need to dig some information out of it:.

This Agreement, including the Exhibits attached hereto, constitutes the entire agreement wrd1114 understanding between the parties hereto regarding the subject matter hereof and supersedes all other agreements, understandings, promises, representations or discussions, written or oral, between the parties regarding the subject matter hereof.

Personally, I can recommend it. Here is nice walkthrough on how to do that. Unfocused for sensing diffused surfaces. The following Sections of this Agreement shall survive the termination or expiration of this Agreement for any reason: Any such audit shall not interfere with the ordinary business srd1114 of Licensee and shall be conducted at the expense of ON Semiconductor.
