Patient monitoring and data processing system

Abstract: The system is composed of a plurality of bedside stations, each in the vicinity of a hospitalized patient, and each interconnected to a central station for monitoring and controlling the bedside stations. The bedside stations contain a plurality of physiological sensing and data sending modules. Each bedside unit contains a central processor for controlling the flow and format of data from the module and to the central station. The central station includes peripheral display units for selectively displaying data from each of the bedside stations. A central processor controls the flow of data from each bedside station to the peripheral displays and for communicating with each bedside processor. Data links are provided for the analog data from the central stations and data links for serial asynchronous data transmission from the bedside station to the central station and for commands from the central station to the bedside station. The waveforms from the bedside stations are frequency modulated through optical couplers to isolate the electric currents between each bedside station while delivering a distortion-free signal. The physiological sensing and data sending modules each include addressable memory which identifies the module to the bedside processor and the central processor. The system includes instructions which automatically perform diagnostic analysis of the circuitry of the system and at regular intervals. The system can be serviced by inserting a diagnostic memory board which displays questions that require responses by an operator which sequentially checks out all circuitry and peripherals of the system.

Constructing stable grasps

Abstract: This paper shows how all force-closure grasps can be made stable by constructing virtual springs at the contacts, such that the grasped object has a desired stiffness matrix about its stable equili...

The insulated gate transistor: A new three-terminal MOS-controlled bipolar power device

Abstract: A new three-terminal power device, called the insulated gate transistor (IGT), with voltage-controlled output characteristics is described. In this device, the best features of the existing families of bipolar devices and power MOSFET's are combined to achieve optimal device characteristics for low-frequency power-control applications. Devices with 600-V blocking capability fabricated using a vertical DMOS process exhibit 20 times the conduction current density of an equivalent power MOSFET and five times that of an equivalent bipolar transistor operating at a current gain of 10. Typical gate turn-off times have been measured to range from 10 to 50 µs.

Mechanism of Solid‐state Reaction Between Magnesium Oxide and Aluminum Oxide and Between Magnesium Oxide and Ferric Oxide

Abstract: Inert marker experiments have shown that the solid-state reactions forming MgAl2O4 and MgFe2O4 occur by counterdiffusion of the Mg2+, Fe3+, and A13+ ions through the relatively rigid oxygen lattice of the spinel or ferrite. It is suggested that earlier claims that ZnAl2O4 forms by diffusion of Zn2+ and O2- ions were probably due to a splitting of the markers, leaving some marker on the specimen surface. Pores in one component of a reacting couple are shown to serve as inert markers. The formation of those materials, e.g., ferrites and stannates, which dissolve marker materials can now be studied.

Use of mutter mode in asset tracking for gathering data from cargo sensors

Abstract: The condition and/or integrity of goods is monitored while in transit using a local area network of tracked assets. Autonomous electronic sensors are situated in proximity to the cargo being shipped. These sensors communicate with an asset tracking unit affixed to the container for the goods via a mutter mode transceiver. The tracking unit has the ability to relay the cargo sensor data to the central station on demand, on exception, or on a predetermined schedule established by the central station. Communication between the cargo sensors and the tracking unit may be one-way (i.e., sensor to tracking unit) or two-way. Multiple sensors may communicate with each tracking unit.
