Creating a Wireless Temperature Sensor |

Designing a wireless temperature measurement sensor for meat processing
It took over 3 years to design an accurate and reliable temperature measurement sensor for the meat processing industry. Frequency of operation, product enclosure and data collection methods were carefully designed to accommodate the harsh conditions these wireless temperature measurement sensors operate in.
The frequency of operation needed to be chosen carefully. The meat processing oven is basically a giant metal box. The higher frequencies have a hard time going through metals and liquids at low power or have problems with longer distance of travel. 433 MHz was chosen for the frequency of operation to allow for the clearest signals in the environment it operates in.

FDA Compliant Wireless Temperature Probe! |

A New Standard in Meat Processing: Wireless Temp Measurement
The FDA requires that the internal temperature of meat be measured once every minute during meat processing and cooking. This is to ensure that the meat is cooked to the proper temperature and also cooled at the correct rate. Traditional methods of doing this include either inserting a cabled thermocouple or a meat thermometer into the product. The problem with the cabled thermocouples is the fact that they have cables. These greatly restrict their ability to move around in the cramped industrial ovens and are also a weak point that is susceptible to breaking. The problem with the meat thermometer is that it has to be manually checked, which means opening the oven to check. Matrix Product Development has spent the last three years developing and producing a wireless solution for meat processing.

Dead Reckoning: Finding Your Way Inside
Global Positioning Satellites (GPS) are in most portable electronic devices that can connect to a network. This technology has revolutionized travel. They essentially eliminated the ability to get lost, assuming the user knows how to operate it. This technology only really works outside though. What about when someone wants to know how to navigate inside a building? Dead Reckoning, or a system that can remember where a device has been in a room/building, could be an answer to this problem.

The Greatest Bluetooth Yet? |

Ultra-Low Power Bluetooth
There are over 2 billion devices in use today that are Bluetooth capable. These devices are used in a wide variety of applications, from the standard wireless earpiece for the cell phone and wireless connections for gaming devices, to healthcare and wireless security applications. As with every wireless industry, however, battery life is a big issue. Out of the desire for greater battery life, Ultra-Lower Power (ULP) Bluetooth was born.

RFID to Revolutionize the Grocery Shopping Experience
Everything is going wireless nowadays. Think of everything that can be done on your phone or computer that was inconceivable ten years ago. Security companies are setting cameras up in homes so people can monitor activity from their phone when they are not home. Cable companies are allowing people to access their home DVR systems through their phones and computers to watch TV recordings anytime. The possibilities are becoming endless on what can be accomplished through handheld devices. Now imagine some of those same technologies entering local grocery and convenience stores to help with the shopping process.

Security Affecting NFC Enabled Smartphones |

NFC on smartphones: a safety assurance
One of the big tech advancements coming in 2012 will be the addition of NFC, or near field communication, to smartphones. The iPhone 5 due out in June 2012 will surely have the technology. What is NFC exactly? It will allow your smartphone to talk back and forth with other devices, such as payment kiosks and check-in’s. Think of going to a store and instead of getting a credit card out of your wallet, simply swipe you smartphone at the checkout and your account will automatically be charged. No carrying cards or cash. Projections are that 1 in 5 cell phones will have NFC technology by 2013.

RFID And Shopping
Radio Frequency Identification (RFID) is an important complementary technology. In the 1980's, there was a push to barcode all items at stores. The change in the shopping experience was dramatic. You no longer needed to wait for check-out staff to tabulate totals or compute savings from coupons. For management, prices could be set at a central location.

RFID function as a GPS system? |

GPS and RFID
Passive radio frequency tags are relatively inexpensive to manufacture and embed with a small amount of binary information. This allows them to become a “Swiss army knife” solution to a multitude of problems, such as inventory management, pet identification, or personnel tracking. There seems to be few places the tags aren't being put.

A Year Away from MS Office |

A Year Away From The Office 
Just over a year ago, LibreOffice became the offshoot of the popular OpenOffice application suite. At that time, I switched over, both on the Windows workstation (required at work) and the home Mac. It was a deliberate attempt to move away from Microsoft Office. I had been using OpenOffice at home and sporadically at work since it first appeared.

Barriers to technology: surgery room inventory management systems??? |
|
Tuesday, 29 November 2011 18:38 |
Why are surgical inventory management systems not more readily implemented? 
More than a couple of people have told me that typical hospitals with multiple room surgery centers lose hundreds of thousands of dollars every year due to inaccurate record keeping of physician preference items.
Many are using very manual methods of tracking inventory levels, expiration dates, and product recalls using high salary staff. To put this in perspective, it is a big task to have the correct inventory on hand for a constantly changing usage requirement. Some inventory is on consignment and most items have critical expiration dates that must be monitored every couple of days.

Pharmaceutical Supply Chain needs RFID |
|
Tuesday, 29 November 2011 18:32 |
RFID is very much needed in Pharmaceutical Supply Chains 
According to the Office of Compliance at the Food and Drug Administration, 80% of active pharmaceutical ingredients in the U.S. today come from manufacturing facilities outside of the United States. The number of pharmaceutical ingredients produced at foreign facilities doubled between 2001 and 2007. What previously was an American drug supply is now a world drug supply. Why did this happen? Cost pressures drove manufacturing costs overseas where overhead costs and labor are less expensive. Therefore, pharmaceutical drugs that many of us rely on every day and pick up at Walgreens and CVS come from a foreign manufacturing facility.
