Telemedicine Robots Bring Expertise to Remote Areas

There was a time telemedicine meant holding a heartrate monitor up to the phone receiver to play an audible signal. Modern telepresence robots like the RPVita from InTouch Health do more than put a patient’s diagnostic information in the hands of an offsite doctor, they create a virtual presence that allows physician and patient alike to have an experience startlingly close to the real thing (see figure 1). With sophisticated controls, advanced imaging, and small, quiet FAULHABER DC motors from MICROMO, InTouch brings top-flight medical care to the farthest reaches of the globe.

Visual Image Sensor Organ Replacement

This innovation is a system that augments human vision through a technique called “Sensing Super-position” using a Visual Instrument Sensory Organ Replacement (VISOR) device. The VISOR device translates visual and other sensors (i.e., thermal) into sounds to enable very difficult sensing tasks.

A Novel Protocol for Decoating and Permeabilizing Bacterial Spores for Epifluorescent Microscopy

This technique can be used in semiconductor, pharmaceutical, and food processing industries. Based on previously reported procedures for permeabilizing vegetative bacterial cells, and numerous trial-and-error attempts with bacterial endospores, a protocol was developed for effectively permeabilizing bacterial spores, which facilitated the applicability of fluorescent in situ hybridization (FISH) microscopy. Bacterial endospores were first purified from overgrown, sporulated suspensions of B. pumilus SAFR-032. Purified spores at a concentration of ≈10 million spores/mL then underwent proteinase-K treatment, in a solution of 468.5 μL of 100 mM Tris-HCl, 30 μL of 10% SDS, and 1.5 μL of 20 mg/mL proteinase-K for ten minutes at 35 ºC. Spores were then harvested by centrifugation (15,000 g for 15 minutes) and washed twice with sterile phosphate-buffered saline (PBS) solution. This washing process consisted of resuspending the spore pellets in 0.5 mL of PBS, vortexing momentarily, and harvesting again by centrifugation. Treated and washed spore pellets were then resuspended in 0.5 mL of decoating solution, which consisted of 4.8 g urea, 3 mL Milli-Q water, 1 mL 0.5M Tris, 1 mL 1M dithiothreitol (DTT), and 2 mL 10% sodium-dodecylsulfate (SDS), and were incubated at 65 ºC for 15 minutes while being shaken at 165 rpm.

Method and Apparatus for Automated Isolation of Nucleic Acids from Small Cell Samples

Advantages include reduced or eliminated use of toxic reagents and operator-independent extraction. RNA isolation is a ubiquitous need, driven by current emphasis on micro-arrays and miniaturization. With commercial systems requiring 100,000 to 1,000,000 cells for successful isolation, there is a growing need for a small-footprint, easy-to-use device that can harvest nucleic acids from much smaller cell samples (1,000 to 10,000 cells). The process of extraction of RNA from cell cultures is a complex, multi-step one, and requires timed, asynchronous operations with multiple reagents/buffers. An added complexity is the fragility of RNA (subject to degradation) and its reactivity to surface.

Enabling Microliquid Chromatography by Microbead Packing of Microchannels

The microbead packing is the critical element required in the success of onchip microfabrication of critical microfluidic components for in-situ analysis and detection of chiral amino acids. In order for microliquid chromatography to occur, there must be a stationary phase medium within the microchannel that interacts with the analytes present within flowing fluid. The stationary phase media are the microbeads packed by the process discussed in this work. The purpose of the microliquid chromatography is to provide a lightweight, low-volume, and low-power element to separate amino acids and their chiral partners efficiently to understand better the origin of life.

On-Command Force and Torque Impeding Devices (OC-FTID) Using ERF

This technology is applicable as a rehabilitation or exercise device. Various machines have been developed to address the need for countermeasures of bone and muscle deterioration when humans operate over extended time in space. Even though these machines are in use, each of them has many limitations that need to be addressed in an effort to prepare for human missions to distant bodies in the solar system.

Physical Security Solutions For Healthcare Equipment

New regulations for data protection and patient information as mandated by the healthcare industry continue to present challenges for healthcare facilities when it comes to security. Failure to ensure that the medical equipment housing confidential patient records and drugs is adequately protected can result in costly fines and penalties.
