Patent GB-2002983-A (GB)
Title: Threshold circuits for alternating signals
IPC: H02P29/00
Filed: 1978-08-15
Abstract: In monitoring an alternating signal it is known to rectify and smooth the signal and apply it to one input of a comparator which has a direct reference potential applied to its other input. Good smoothing is necessary to avoid a continuous change in the comparator output so that the comparator shall act as a threshold circuit but this unfortunately results in a correspondingly large time delay in response. In the present invention, a comparator circuit IC1 is arranged to respond to instantaneous changes in the waveform of the alternating signal IM and has its output connected to a bistable circuit IC2 which has a substantially instantaneous switching characteristic in one direction but has a delay characteristic in the opposite direction. A principal use of the invention lies in the automatic control of a refrigeration compressor driven by an alternating current motor. Feedback via R4 provides hysteresis by reducing the threshold voltage VE when two consecutive pulses exceed the original threshold level, R6, C2 providing the delay. <IMAGE>

Abstract: A blood sampling system includes an indicator 98 for successful venipuncture before sampling. A cannula 22 open at both ends has a front end 30 for venipuncture and a rear end 32 for coupling with an evacuated sample container 26. The container 26 has an open end closed by a self-sealing stopper 78. The stopper 78 can be penetrated by the rear end 32 of the cannula 22 to provide communication for blood between the cannula 22 and the interior 90 of the container 26. A diaphragm 92 in the container 26 deforms when end 30 of the cannula 22 is introduced into the vein and the end 32 is introduced a predetermined distance into the stopper 78. The deformation permits a small amount of blood to enter the cannula 22 to show a successful venipuncture. An indexing structure 66, 68 on the holder 24 and container 26 facilitates relative positioning of the stopper 78 and cannula end 32 for operation of the indicator 98. <IMAGE>
