MEMSIC Introduces World’s Smallest and Most Robust Digital Accelerometer With Features Never Before Available at This Price- Point
MEMSIC Inc.a leading provider of MEMS devices and sensor- based systems has announced the availability of its MXC6226XC MEMS two-axis digital accelerometer, the world’s smallest, fully-integrated MEMS accelerometer. Based on MEMSIC’s patented MEMS thermal technology, it is manufactured using a standard 0.18um CMOS process and advanced wafer- level packaging (WLP). The resulting device demonstrates MEMSIC’s leadership in providing state-of-the-art motion sensing functions at a price- point never before available to designers of cost sensitive systems like cell phones, toys, games, cameras and appliances. The MXC6226XC accelerometer provides superior performance and functionality to designers who have previously not been able to consider motion sensing for their products. MEMSIC’s MXC6226XC enables designers to significantly enhance the value of their product. It also serves as a high value-added replacement to designs employing mechanical switches, which are much less reliable and less capable.
STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications and the leading supplier of MEMS (Micro-Electro-Mechanical Systems) for consumer and portable applications1, expanded its sensor portfolio with a new high-performance, low-power digital MEMS microphone. Housed inside an ultra-small 3x4x1 mm package, ST’s MP34DT01 top-port microphone delivers a best-in-class audio experience in mobile phones, tablets and other smart consumer devices.
CoventorWare uses FlexLM for licensing and requires the port@host information for accessing licenses. CoventorWare cannot access the license if the port number in license file and User settings do not match. Please follow the instructions below to resolve problems due to incorrect port numbers.
A firewall on your network can cause license problems. This problem is only encountered when the client (the computer on which you are running Coventor software) is trying to access a license from the server across a network. The client machine must be able to access two different ports on the license server machine. The first port is the port at which the daemon lmgrd runs (typically 54000 for CoventorWare) and the second port is the port at which vendor daemon runs. You can check the ports that are being used in the licensing log file. For example, the figure below shows CoventorWare-mcosmld.log file with the port numbers for CoventorWare.
The vendor daemon port is a default port and its number will change each time license server is restarted. To specify a fixed port for vendor daemon, add
port= User Specified Port Number
at the end of VENDOR line in the license file. For example, the figure below shows CoventorWare license file with 54001 as the port for vendor daemon.
After making this change, stop and restart the license and re configure your network firewall to open these two ports to the client computers that need to access them. Your network administrator will be able to do this for you.
Open up the Task Manager and check if lmgrd.exe is running. A screenshot of the Task Manager is shown below:
You can telnet to the port at the server to check if the server machine is up and running. Go to Start-Run , type in cmd and hit Enter. This will open up a command prompt. Type telnet license_server_name port_number and hit Ener. If it connects, you know the port is in use. If it doesn’t connect , it will immediately return with an error. The figure below shows the results of a failed telnet test. In this example, the name of the license server is red and the port number is 54009.This test ensures that the server machine is running.
The users can also run the lmstat command to ensure that the license server is running. Go to Start-Run , type in cmd and hit Enter to open a command prompt. Use the cd command to navigate to C:\Coventor\CoventorWare2008\licensing\NT40 directory. Type lmstat -a -c port@host -i and hit enter. If you get an error, it means license server is down. The figure below shows the use of lmstat command. The name of license server is red and the port number is 54000.
Open up the CoventorWare-mcosmld.log file. Check if the file has message shown below:
This indicates that the license feature has expired. Please contact Coventor Technical Support at firstname.lastname@example.org. Do not try to edit the end date in license file, doing this will invalidate the license file.
Please note that this is just an example, you may have other features which are expired.
Open up the CoventorWare-mcosmld.log file . Check if the file has message shown below:
Open up CoventorWare license file with a text editor, for example Notepad and check the Start Date. If the Start Date is in the future, please contact Coventor Technical Support at email@example.com. Do not try to edit the Start Date; this will invalidate the license file.
Please note that this is just an example. You may have features with different Start Dates in your file.
Understanding the CoventorWare license files
This section explains the different features in license file
- A typical license file will have a few lines beginning with #. Any line beginning with # is commented and will not be read by the License Installer
- Scroll down till you reach the first uncommented line. Figure below shows the screenshot of this section of the license
- In this case lt1-skedar is the host-name i.e. name of the computer for which license was issued, 000D56A8B1F3 is the hostid i.e. the MAC address. 54000 is the port number. You can edit the host name and port number, but not the host id. If you edit the hostid, your license file will not work.
- The lines following the server line determine the features your have, start date and end dates for license file, codes etc.
