Abstract: A sleeve for use with a tourniquet cuff to protect a patient's limb from tourniquet-related injury includes a stretchable body extending longitudinally over a sleeve length between a proximal end and a distal end. The body has a tubular shape, and the sleeve length is greater than a width of the tourniquet cuff. The body tapers from the proximal end to the distal end such that a proximal end circumference is greater than a distal end circumference. The body is formed to apply substantially uniform pressure to the patient's limb from the proximal end of the sleeve to the distal end of the sleeve varying only within a predetermined pressure range.

Abstract: A real-time magnetic digital video disk recording system has been developed for applications in on-line digital imaging systems and off-line fast access image storage and retrieval buffers. The disk recorder uses new high density recording technology and Winchester computer drive technology in a unique peripheral configuration which is fully synchronized to video system timing, provides for flexible formatting, achieves fast random access to a large video image file, and eliminates the need for complex data controllers. The recorder includes two independent actuator and head assemblies for alternately recording successive video fields on separate tracks on separate zones A and B of a disk stack. Movement of one of the actuators and head assemblies is controlled and occurs within a field time to skip tracks containing media flaws to achieve real time digital video recording.

Abstract: An AGC amplifier having a fast response for recovery and reacquisition of gain control in microseconds after a signal break including a first and second amplifiers interconnected by a delay line equalizer. An integrator control loop is responsive to the output of the second amplifier and is connected to the control means provided on the first amplifier and includes a feedback loop having a peak detector, an ideal integrator connected to the output of the peak detector and directly controlling the first amplifier using an ideal integrator capacitor loop during control operation and having a switch removable reset loop for operating as a fixed high gain amplifier in the absence of signal. The latter is determined by a comparator operating to receive a second peak detector signal not in the control loop.
