摘要： A lancet injector is provided which has a tubular housing, a slidable lancet holder in the housing, a compression spring connected between the holder and one end of the housing, and a holder control member extending through a longitudinal slot in the sidewall of the housing. The control member is operable to move the lancet holder to a latched retracted position against the force of the spring, release the holder so that it moves linearly under the force of the spring and inertia to a skin piercing position and then back to a neutral position in which the spring is in a free length condition.

摘要： A blood collection tube is provided with a blood phase partitioning device disposed in the upper portion or adjacent the low density blood phase end of the tube. The device carries blood phase barrier gel-like material which flows through a restricted orifice in the device to meter or reduce the flow rate of the material into the blood during centrifugation to suitably delay the formation of the complete phase barrier until complete blood phase separation has taken place.

摘要： A method of demodulating a pulse width modulation encoded analog signal wherein the analog signal is retrieved from individual pulse width modulation cycles. A method of sampling and outputing the retrieved analog signal only if missing pulse detectors confirm that the pulse width modulation cycle was valid. And a method generating a second but inverted play-back signal permitting use of two identical pulse width modulation transition descriminators-detectors.

摘要： An economical, practical method of bringing the major portion of a classroom teaching experience to a remote student. The teacher's oral and blackboard presentations are recorded, forwarded to the student and played back on equipment that reproduces the teacher's voice and his or her graphics that would normally be presented on a blackboard, retaining the time correlation between the spoken and written texts.

摘要： A fluid collection device for receiving a liquid, such as blood, and which is adapted to be centrifuged to separate it into its relatively light and heavy phases. The collection device has a phase partitioning device having a specific gravity intermediate those of the light and heavy phases of the blood so that it automatically moves during centrifugation to substantially the interface of the phases to sealingly partition them from each other. The device has a resilient sealing member which is of conical or "umbrella" configuration, and another member of different specific gravity connected to the sealing member and having stabilizing members for maintaining the sealing member properly oriented in the container. The sealing member partially collapses during centrifugation to allow blood components to pass by the sealing member. As the phases become separated and the centrifugal forces decrease, the sealing member expands radially outwardly and sealingly engages the walls of the container providing a barrier between the light and heavy phases upon complete phase separation.
