Artificial Pancreas

Artificial Pancreas

People with diabetes have a range of technologies to help keep their blood sugar in check, including continuous monitors that can keep tabs on glucose levels throughout the day and insulin pumps that can deliver the drug. But the diabetic is still responsible for making executive decisions--when to test his blood or give himself a shot--and the system has plenty of room for human error. Now, however, researchers say that the first generations of an artificial pancreas, which would be able to make most dosing decisions without the wearer's intervention, could be available within the next few years.

Artificial pancreas: Scientists are pairing continuous glucose monitors, such as the device pictured here (white device, top), with insulin pumps, such as the one pictured here (pagerlike device, bottom), to create an artificial pancreas for people with diabetes. In this commercial system by Medtronic, the glucose monitor wirelessly transmits data to the pump via a meter. However, the user must still decide how much insulin he needs and dose it out himself. In an artificial pancreas, specially-designed algorithms would calculate how much insulin is required, and how quickly, and then signal the drug’s delivery without human intervention.

Kenyan Teenager turns mobile phone into vehicle anti-theft system

A young kenyan boy named Morris Mbetsa, with no formal training beyond a high school diploma, has invented a system that will alert the user via mobile phone if his or her car is started. Then the owner can decide whether to call the cops, kill the cars engine by sending it a code, or listen in on the presumed theives' conversation.

The system, that Mbetsa created by combining technology from projects that he has completed in the past, uses a combination of voice, DTMF and SMS text messages over cell-based phone service to carry codes and messages that allow control of some of a vehicles’ electrical systems including the ignition to manage vehicle activation and disabling remotely in real time.

Another feature of the system is the capacity to poll the vehicle owner by mobile phone for permission to start when the ignition is turned in real time as well as eavesdrop on conversation in the vehicle.

Single-insertion, multi-sample biopsy - Flash

Single-insertion, multi-sample biopsy - Flash

Flash, a single-insertion, multi-sample (up to 15 samples) breast biopsy gadget that collects cored samples from different locations in a special chamber. Guided by ultrasound, Flash utilizes real-time visualization and automated sampling to obtain solid, contiguous biopsy cores. Other biopsy devices and techniques require several individual insertions into the patient’s breast to retrieve adequate samples for pathology analysis.
