Abstract: An array of plural magnetic resonance imaging (MRI) RF coils is provided having different and overlapping fields of view. Controllable switches (52) are connected with each individual coil (16, 18) of the array and are capable of selectively conditioning any one of the coils for individual usage in an MRI procedure. Either mechanical or electrical (e.g., PIN diode) switching control (52) may be utilized. Preferably, controllable electrical switches are located at points having approximately zero RF potential. Distributed capacitance (C D ) is also preferably employed for reducing terminal inductance, preventing the establishment of spurious magnetic fields and facilitating the use of electrical switching diodes and/or varactor capacitance elements. Such distributed capacitances are also dimensioned so as to cause the terminal inductance of each coil to be within the tuning/matching range of a common tuning/matching RF circuit (24).

Abstract: A differential pulse code arrangement reduces the bit rate of a composite color video signal by sampling the video signal at a predetermined rate of  m  times the color sub-carrier frequency, predicting the present video signal sample from reconstructed past samples and forming signal representative of the prediction error in a first predictive loop. The bit rate is further reduced in a second predictive loop embedded in the first predictive loop by generating a signal predictive of the error signal and forming a signal corresponding to the difference between the error signal and the signal predictive thereof. The difference signal is quantized and encoded for transmission. The error signal is reconstructed by summing the quantized difference signal and the predicted error signal and the prediction of the error signal is formed responsive to the sequence of past reconstructed error signals. The m-1th video signal sample is then reconstructed by summing the reconstructed error signal and the signal predictive of the m-1th video sample and a signal predictive of the next occurring video sample is generated responsive to the sequence of past reconstructed video samples.

Abstract: The process involves creating and running a special program in the virtual machine which is to be accorded suspend and resume control functions. The suspend/resume control function program is run first before a user's task is run. The special suspend/resume program seizes control over the virtual machine's external interrupt controls and modifies them to direct all incoming interrupts to the program itself rather than allowing CMS of the virtual machine to handle interrupts as is normally done. With incoming interrupts being sent to the suspend/resume program for analysis and response, incoming commands that generate such interrupts may be responded to and sub-routines contained within the suspend/resume task program may be employed to save all of these addressing registers and general register contents. This effectively takes a snapshot of the present status and intermediate result conditions existing in the user's task program operation at the time the interrupt occurred, thus enabling the restoration at a later time from the point at which suspension of the task occurred. The suspend/resume task program operates to modify the interrupt controls of the virtual machine to create a suspension of operation of the user's task program by enabling the virtual machine only for external interrupts.

Filed: 1990-04-12
Abstract: A MOS transistor (Q M ) detects an increase of the collector current (I C ) of an IGBT device (Q₀). When an excess current flows, the transistor (Q M ) turns on, which restricts the gate voltage (V G ) of the IGBT device (Q₀) to decrease the collector current (I C ). This protects the IGBT device (Q₀) from the ex­cess current. A Zener diode (D Z ) placed in a path which is for detecting the excess current of the IGBT device (Q₀) restricts the current passing through the path. This decreases a reac­tive power which is consumed in protecting the device (Q₀) from the excess current while protecting a drive circuit from an erroneous operation.

Abstract: Compositions which are made up of acrylamide functional polyorganosiloxane and other non-silicon ingredients are compatible when the polyorganosiloxane contains from 5 to 50 mole percent aromatic groups bonded to the silicon atoms. These compositions can contain reactive diluents, photoinitiators and other non-silicon compounds. The compositions have low temperature properties and cure faster when exposed to ultraviolet radiation as the aromatic content increases. The compatibility with non-silicon compounds increases as the aromatic content increases and the spectrum of kinds of compounds and their amounts increases with increasing aromatic content. These compositions are useful in the electrical and electronic industry.
