And Control

Recent developments in device technology and widespread use of cell phone and wireless technology globally have provided an unprecedented opportunity for enhanced healthcare delivery. This study presents development of a cell phone based electronic healthcare system for remote monitoring and control of patients. The system comprises of two modules, each connected to a cell phone for communication of data or instructions. The first module allows real-time data acquisition and analysis from several devices that may be connected to the patient. By calling the cell phone for this module, data can be accessed or any of the connected devices be controlled remotely. Any observed abnormality is reported in real-time by calling a pre-set cell phone. This module allows interactive communication utilizing machine generated voice. Also, this module calls the second module at regular time intervals to transfer the patient’s data over phone. The second module thus receives the data for storage in a central location. All of these features of the system were tested successfully on simulated patient devices. For data and device security, ID and password verifications are required.

Virtual reality (VR) is usually described by the media as a particular collection of technological hardware: a computer capable of 3-D real-time animation, a head-mounted display, and data gloves equipped with one or more position trackers. However, this focus on technology is somewhat disappointing for communication researchers and VR designers. To overcome this limitation, this paper describes VR as a communication tool: a communication medium in the case of multiuser VR and a communication interface in single-user VR. The consequences of this approach for the design and the development of VR systems are presented, together with the methodological and technical implications for the study of interactive communication via computers.

Quiescent Prominence

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.

Capture Techniques

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.

Diffraction Patterns

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.
