    摘要： Failsafe apparatus and method are disclosed for controlling fluid flow from syringes. One or more syringes are positioned so that the piston of each syringe is caused to be precisely displaced to thereby safely deliver medicament from the syringe to a patient. To effect movement of each piston, a rack is provided, either as a part of the piston or secured thereto, and longitudinal movement of each rack is effected by rotating an associated pinion gear that is connected with a pulse-driven, stepper motor utilized in a power-efficient electromechanical configuration, with the operation of the stepper motor being accomplished through dual-redundant state machines controlled by a pre-programmed memory unit, and with the apparatus being repeatedly subjected to a plurality of error checks and data integrity verifications to assure continued proper operation.

    摘要： A syringe positioning device is disclosed for enhancing control of fluid flow from a syringe. A disposable unit that includes a syringe and rack mounted on a retaining clip is positionable on a drive unit so that, when so positioned, the piston of the syringe is precisely displaced to deliver medicament from the syringe to a patient. A non-disposable unit is also disclosed onto which a syringe and piston can be positioned so that the device thereafter also provides precise medicament delivery. The longitudinal movement of the rack is effected by rotating the pinion gear that is connected with a pulse-driven, power efficient stepper motor, with the operation of the stepper motor being controlled by a pre-programmed memory unit. A hinged rack is also disclosed, as is a one-way ball drive unit.

    摘要： In a system having a frequency encoded data stream and a source of clock signals phase locked to the data stream, for subsequent demodulation of the data stream, the clock source is at a frequency that is a multiple of the nominal frequency for demodulating, and a counter is employed to divide the clock. The counter is controlled by the output of a phase comparator, to control the addition to and inhibiting of counting of the counter. The control circuit controls the counter in a non-linear relationship with respect to the phase error, and has a memory function for storing previous states of the counter, to permit repetitive correction for small errors in the same manner. The phase comparator and control are preferably a programmed logic array.

    摘要： The broadcast audio signal and/or the broadcast video signal of a monitored broadcast are temporarily stored and predetermined signal events are detected which indicate possible new broadcast segments of interest of the monitored broadcast. Intervals of the monitored broadcast are selected as possible new broadcast segments of interest based on the predetermined signal events. A first capture level is assigned to a first selected interval based on predetermined characteristics of the interval which indicate that it is likely to be a new segment of interest. A second capture level is assigned to a second selected interval based on predetermined characteristics of that interval which indicate that it is relatively less likely than the first selected interval to be a new segment of interest. A signature corresponding with the first selected interval is stored in the database and the temporarily stored broadcast audio and/or video signals which correspond with the first selected interval are captured for transmission to a workstation operator for segment identification. A signature corresponding with the second selected interval is stored in the database and the temporarily stored broadcast audio and/or video signals which correspond with the second selected interval are erased.

    摘要： Distance measurements are made using two or more signal frequencies. Ultrasonic energy is transmitted from a transducer to an object. Returned ultrasonic energy is received by the transducer and processed to provide an accurate determination of the distance between the transducer and the point on the object receiving the ultrasonic energy. In connection with the processing, a number of relationships are utilized. Using certain of the relationships, a range of integers is determined using high and low frequency ultrasonic energy, as well as propagation time. A time-related phase shift determination is also made for each of the high and low frequencies using certain of the other known relationships. Using a range of distance values and the measured time-related values, an accurate determination of distance from the transducer to the object can be made. In one application, a number of different distance values are obtained to define the surface plane of the object, such as a wheel or tire.
