Abstract: A device for indicating the respiration movements on a recorder, without being affected by external pressure, comprises at least two piezoelectric transducers (7, 7′) which are built oppositely each against the other, embraced by a metallic member, and a membrane (3) possessing a wave-like shape. The entire device is enclosed in a housing (2) open at its two ends. Upon stretching said membrane (3), the piezoelectric transducers (7, 7′) generate an electric signal, according to the respiration movements, any external pressure being cancelled by the action of the transducers. The electric signal is indicated on a strip chart recorder. The device has the advantages of prolonged use time and very high sensitivity which imparts high accuracy and therefore provides correct respiration data.

Abstract: A system for regulating an output voltage to a particular value includes a control transistor which produces an output voltage when energized by an energizing voltage. A voltage divider formed as by a pair of transistors with a particular ratio of transconductances divides the magnitude of this output voltage by a ratio related to the ratio of the transconductances. The transistors in the voltage divider may be respectively CMOS n- and p- transistors. The divided output voltage is introduced to a comparator (formed as from a pair of transistors) for comparison with a fixed reference voltage obtained as from a resistance ladder energized by the energizing voltage. The comparator introduces voltages to a comparator amplifier in accordance with such comparison. The comparator amplifier may include a transistor which produces changes in a current related to changes in the divided output voltage. The comparator amplifier may further include a current mirror which provides changes in a current related to changes in the current through the amplifier transistor. The current changes in the current mirror cause changes to be produced in a voltage (e.g. error voltage) from the current mirror. These error voltage changes are introduced to the control transistor to regulate the output voltage to the particular value.

Abstract: Radiant energy mixing structures are known. However, such structures tend to be expensive, relatively large and heavy. Described herein is a high efficiency optical mixer (22) and a method of operating such a mixer which overcomes these disadvantages. The optical mixer (22) includes a source (14, 16, 18, 20) of focused radiant energy. The focused radiant energy is concentrated by a concentrator (26) on to an exit port (28c). A diffuse reflector (36), which can be planar or arcuate, is maintained in contact with the exit port (28c) thereby minimizing optical losses and diffusely reflecting light from the concentrator. The reflected light can be transmitted, by fiber optic elements (42), to an optical system.

Abstract: A computer system has a plurality of processing units (2-1,2-2,2-n) connected via one or more system buses (1-1,1-2). Each processing unit (2-1,2-2,2-n) has three or more processors (20-1,20-2,20-3) on a common support board (PL) and controlled by a common clock unit (1000). The three processors (20-1,20-2,20-3) perform the same operation and a fault in a processor (20-1,20- 2,20-3) is detected by comparison of the operations of the three processors (20-1,20-2,20-3). If one processor (20-1,20-2,20-3) fails, the operation can continue in the other two processors (20-1,20-2,20-3) of the processing unit (2-1,2-2,2-n), at least temporarily, before replacement of the entire processing unit (2-1,2- 2,2-n). Furthermore, the processing unit (2-1,2-2,2-n) may have a plurality of clocks (A,B) within the clock unit (1000), with a switching arrangement so that the processors (20-1,20-2,20-n) normally receive clock pulses from a main clock (A), but receive pulses from an auxiliary clock (B) if the main clock (A) fails. Switching between the main and auxiliary clock (A,B) involves comparison of the pulse duration from the clocks (A,B). Additionally, a plurality of cache memories (220,221) may be connected in common to the processors (20-1,20-2,20-3), so that failure of one cache memory (220,221) permits the processing unit (2-1,2-2,2-n) to continue to operate using the other cache memory (220,221). Coherence of the contents of the cache memories (220,221) may be achieved by direct comparison, and a comparison method can also be used to invalidate data in an internal cache memory (2020- 1,2020-2,2020-3) of a processor (20-1,20-2,20-3) which differs from that in the external cache memory (220,221). Coherence of protocols may also ensure that data in caches (220,221) of the different processor units (2-1,2-2,2-n) are always correct.

Abstract: A data burst is modulated on an IF carrier, and a spectral null is artificially created in the center frequency region of the spectrum of the modulated data burst by taking the difference between delayed and non-delayed versions of the IF data burst. A sync burst is modulated on the IF carrier so that its spectrum corresponds to the center frequency region of the data burst and superimposed on the IF data burst and transmitted. At a receive site, the IF sync burst is recovered by passing the superimposed IF signal through a bandpass filter having a passband corresponding to the spectrum of the IF sync burst and the IF carrier is recovered from the recovered sync burst. The sync burst at baseband frequency is recovered from the IF sync burst by a demodulator using the recovered carrier. Using the recovered carrier, a baseband sync burst and a baseband data burst having a spectral null are synchronously detected from the superimposed IF signal and fed into a decision feedback equalizer where the original data burst is recovered.

Abstract: A method and apparatus for measuring blood iodine concentration draws a continuous specimen of blood containing iodine from the left ventricle of the heart and exposes that specimen to a source of X-rays. The attentuated level of X-rays passing through the specimen is compared with the unobstructed level of X-rays to determine the concentration of iodine in the blood. The measurement is then corrected to account for the effects of dispersion caused by the travel of the specimen from the heart to the measurement zone.

Abstract: A method is provided for coding an input video signal with a field rate of 60 Hz derived from a motion picture film source using 2-3 pulldown. The method comprises the steps of: detecting duplicate fields in the input video signal; eliminating each duplicate field from the input video signal to produce a progressive video signal comprising plural frames with a frame rate of 24 Hz; and coding the progressive video signal to produce a coded video signal. The step of detecting a duplicate field in the input video signal may comprise generating a control signal in response to each detected duplicated field, and the step of coding the progressive video signal may include the step of including each control signal in the coded video signal. A method of decoding the coded video signal to provide an interlaced video signal with a field rate of 60 Hz comprises the steps of: decoding the coded video signal to provide the progressive video signal; extracting the control signal from the coded video signal; and deriving three fields of the interlaced video signal from certain frames of the progressive video signal and two fields of the interlaced video signal from all other frames of the progressive video signal in response to the control signal.
