GigE-Vision®-Compliant Receivers for the Networked Operating Room

A new type of system offers ultra-low-latency image transmission and low jitter for surgical environments.When vision system integrators are designing systems for hospital operating rooms, they have a number of technologies to choose from. The video interfacing technology with which the system will transmit imaging data to PCs or other system elements has traditionally been limited to point-to-point connections. However, as medical diagnostics and image-guided surgery grow in sophistication and demand, the need for a networked video architecture in the operating room also grows.

Preserving Phase for Bionic Implants by Rearranging a Signal’s Components

A method uses basic mathematical theories to provide original phase information and improve end-user perception experience in users of cochlear and other bionic implants.Any signal can be decomposed into components of sinusoids. This pioneer technique expands the theory of interchangeability of phase and a shift of time (or a shift of another variable). It faithfully preserves phase information by mathematically rearranging the signal’s component to another time or place and assigns all the processed components a single user-defined phase. Since reconstructing the processed single-phase components highly approximates the original signal, this fundamental method can be widely used in fields that require phase preservation by single-phase stimulation, such as bionic implants (e.g., cochlear implants and retinal implants), and areas that need to preserve phase reliably and make all signal components share one universal phase.

Thermographic Printing Using Organic Silver Salts

Light-sensitive and light-insensitive materials generate black and white images by the use of heat; no ink is required.The materials presented allow the writing on a single sheet of these materials without ink, but only by heat, thereby revealing a black and white image. This process is called thermographic writing or printing.

Retractor System for Abdominal Surgery

The operating field can be increased or decreased using one hand to move the retractor hooks.Adjusting abdominal clamps to open up a larger operating field during surgery typically requires the use of two hands: one hand to unscrew the clamp, and the other hand to pull the clamp to increase the operating field. Furthermore, one hand has to retain the clamp in position while the other is used to fasten the tension screw. This can be inconvenient during a surgical procedure when the surgeon may only have one hand available. If this happens during an emergency and one of the surgeon’s hands is occupied, assistance is required to move the retraction hook to a new position. Due to limited space around the operating table, this is particularly difficult when the retraction hook needs to be moved in the direction of where the surgeon stands.

Repeatable, Low-Cost UV Assembly of Biosensors

UV spot curing system ensures greater accuracy for automated and manual manufacturing of biosensors.A biosensor is an analytical device that converts a biological response into an electrical signal. It is increasingly being used as a cost-effective diagnostic tool that offers the capability to render efficient, easy-to-use, and accurate diagnosis. While technological advances in biosensors are allowing this technology to cater to an extensive range of applications in a number of fields, such as industrial and environmental testing, the largest applications have been in the healthcare sector, including glucose detection, pregnancy testing, blood testing, breath analyzers, and cancer diagnosis.

Tethered Endoscope for Photographing the Esophagus

Unlike conventional endoscopes and camera pills, the system does not require an expensive external support system, batteries, memory, or processing electronics.Conventional endoscopes are the “gold standard” for investigating and evaluating mucosal disease of the esophagus. Free-swimming camera pills are large because they must carry camera, batteries, memory, illumination, and some level of image processing power on board. A typical camera pill may measure 11 x 26 mm and may be priced at $1500 per pill — and the pill is not reusable. Camera pills are difficult if not impossible to steer from outside the body. Both camera pills and conventional endoscopes require an expensive external support system. Camera pills may not return information for over 24 hours, until the body eliminates them.

Isolation of the Paenibacillus phoenicis, a Spore-Forming Bacterium

A microorganism was isolated from the surfaces of the cleanroom facility in which the Phoenix lander was assembled. The isolated bacterial strain was subjected to a comprehensive polyphasic analysis to characterize its taxonomic position. Both phenotypic and phylogenetic analyses clearly indicate that this isolate belongs to the genus Paenibacillus and represents a novel species.
