RFID Eppendorf Tubes

For some time barcodes and more recently 2D barcodes have been used to label Eppendorf tubes (small vials that typically hold 1.5ml and are frequently used e.g. in molecular biology). Passive RFID tags should be an even better alternative as they can be much smaller (less than 1 x 1 mm), but could hold more data than a barcode. Biobanking (a collection of biological samples stored e.g. in a freezer) and tracking samples could potentially be easier. However, as these reaction tubes are considered as "consumables", the adoption of RFID technology will probably only take place for tubes intended for sample storage as the cost for producing the tags is still too high.

Remote controls via WLAN

Friday, June 13th, 2008 by hinrich

When I look at my laptop and also my mobile phone, it seems to me that the infrared port is dead. There are fewer and fewer electronic devices that are equipped with them. On the other hand, when looking at remote controls, this standard seems to stay even though it has obvious draw backs such as having to avoid obstacles between the sender and the receiver. Why do we not have a general switch to a wireless technology, preferably even making use of the WLAN standard? This could potentially make time consuming exercises - like training a universal remote control - a thing of the past as electronics manufacturers could make their communication codes available via the internet. One could have truly universal remote controls and would not need to juggle four or five device-specific remote controls vs. having one universal remote control with limited functionality...

Contacts for new phones

Just having bought a new phone, I went through the pleasure of configuring it. While many companies nowadays offer the service to transfer your address book from one GSM phone to another, the story is different for transferring info for a new phone at home. Even though we have numerous tools to synchronize things like Outlook contacts with a mobile phone, such service is lacking at home. One possibility could be to have a contacts repository with a service provider that can be both synchronized with computer contacts as well as with phones in general via some standard. Then the time needed to initially type in contacts data / update the phone at home would be limited to configuring the location of the repository.

Then again, this might be a thing of the past anyway looking at the increasing adoption of VoIP.
