Eye movement control of computer functions.

The control of computer functions by eye movements was demonstrated in 14 normal volunteers. Electrical potentials recorded by horizontal and vertical electrooculography (EOG) were transformed into a cursor that represented a moving fixation point on a computer display. Subjects were able to spell words and sentences by using eye movements to place the cursor on target letters in the display of an alphabet matrix. The successful demonstration of computer-controlled syntactic construction by eye movements offers a potentially useful technique for computer-assisted communication in special groups, such as developmentally-disabled individuals who have motor paralysis and who cannot speak.

Mission impossible? The boss wants to double our inventory turns.

Despite the prolific implementation of manufacturing systems, JIT principles, Kaizen events, and cycle time reduction programs over the past few years, high inventories still plague many companies. The assumption that implementing these principles and techniques will automatically result in inventory levels that satisfy management frequently proves to be false. Events like mergers, introduction of new competition, and a dropoff in business often trigger edicts to cut inventories. The cost of inventories also extends beyond the traditional accounting measurements to include hidden operating costs that everyone should want to eliminate. This article looks at the reasons for inventories and explores strategies for reducing them.

[Detection of ischemic muscle necroses using 99mTc perfusion scintigraphy of traumatized extremities].

In the Dr. Horst-Schmidt Kliniken Wiesbaden 19 patients with trauma of the inferior legs have been examined by means of perfusion-scintigraphy with regard to a compartmental syndrome. In the control group there were twelve Patients without trauma. The employed method of computer assisted analysis of function of blood supply of the extremities in connection with the verification of the 99mTC-MDP amassment in the soft tissues seen in follow-up X-rays allows a differentiation between a normal-blood stream raising caused by a traumatic reparation (C = 1.7 +/- 0.6) and the significant higher blood stream as a result of the development of ischemic muscle lesions (C = 3.8 +/- 1.5). This non-invasive method is not very exert for the patient and is practicable with little expense in a nuclear medicine department. It may not be considered as a routine analysis because the clinical signs are sufficient to show the necessity of an immediate operative intervention in order to avoid a compartmental syndrome.
