Method of coupling light via a coupler on a fiber optic light guide

A non-invasive technique for approximating the mean pressure value and blood pressure constant associated with the actual blood pressure in a particular artery of a given subject is disclosed herein. In accordance with this technique, a number of cuff pulses at varying cuff pressures are generated from the actual blood pressure of the subject and the mean value of the cuff pulse having a maximum peak to peak amplitude value is determined. This mean value is utilized as an approximation of the mean value of the patient's actual blood pressure and is also used in combination with the patient's diastolic and systolic blood pressures to provide the approximation of the patient's blood pressure constant.

Technique for obtaining the mean blood pressure constant for an

A technique is disclosed herein for obtaining the diastolic and systolic blood pressures of a particular patient by generating cuff pulses of the patient and using these cuff pulses as the only information relating to the blood pressure of the patient in order to determine the diastolic and systolic pressures.

Techniques for determining different parameters associated with an individual's blood pressure in a non-invasive manner are disclosed herein. These techniques include (1) generating a blood pressure waveform corresponding to the individual's actual waveform, whereby the mean pressure of the individual can be readily calculated, (2) generating a transformation curve unique to the patient from his diastolic and systolic pressures and his cuff pulses (3) successively monitoring certain parameters of the patient's blood pressure including his systolic and diastolic pressures over closely spaced intervals of time without having to subject the patient to cuff pressures much greater than his diastolic pressure, other than initially or not at all utilizing what is referred to as a stat mode, and (4) measuring a patient's diastolic and systolic blood pressures at any given instance without ever having to subject the patient to cuff pressures much greater than his diastolic pressure.

Techniques for determining different parameters associated with an individual's blood pressure in a non-invasive manner are disclosed herein. These techniques include generating a blood pressure waveform corresponding to the individual's actual waveform whereby the mean blood pressure of the individual can be readily calculated. This is accomplished by either using a specifically selected cuff pressure or by ramping the cuff pressure as would be done in taking blood pressure.

Devices for and methods of pressurizing or depressurizing a particular pressurizable container or housing in a substantially linear, fixed manner independent of the pressurized volume of the container are disclosed herein. These devices are especially suitable in an arrangement for taking blood pressure in which a cuff wrapped around a body part of a patient is pressurized or alternatively depressurized to detect the patient's systolic and diastolic pressures. The device acts on the cuff so that the latter is pressurized or depressurized in a substantially linear, fixed manner independent of the pressurized volume of the cuff, that is, independent of the size of the cuff.

Linear pressurizing and depressurizing device

A specific technique for determining an individual's systolic blood pressure is disclosed herein. This technique utilizes the individual's diastolic blood pressure, the patient's arterial curve or amplitude curve, and different assumed systolic pressures for making a comparison between certain assumed curves and a reference curve in order to establish which of the assumed systolic pressures accurately reflects the individual's actual systolic pressure.

A versatile, calibrated cable connector crimping tool capable of crimping a plurality of cable connector sizes and a method of forming a calibrated crimp or a plurality of calibrated crimps in a cable splice connector positioned around a cable splice along a cable using said crimping tool are disclosed. The crimping tool comprises a first die member having a plurality of dies of select sizes, a second die member having a single die of select size, and a hinge joint connecting said die members and allowing them to be swung into engagement. One die member has a die or dies which are spatially fixed to define a fixed die member. The other die member has a moving means along which the die or dies may be moved into a position allowing engagement of the die members to define a movable die member. A die of select size, appropriate as defined herein for the size of the connector and the cable, is selected from among the plurality of dies of the first die member and the movable die member is moved into a position allowing engagement of the die members. The tool is positioned about the connector and struck until said first and second die members engage, thereby forming a calibrated crimp.

Calibrated cable connector crimping tool and method of use

Improved method and apparatus for indicating blood pressure and the like in a varied pressure cuff system wherein blood vessel pulsation signals are supplied to signal processing means for determining the blood pressure. The blood pressure pulsations are monitored to detect artifacts and the signal processing means inhibited if an artifact is detected. Upon detection of an artifact the pressure applied by the cuff is automatically adjusted to repeat the pressure at which the artifact is detected, thereby to seek artifact-free values. The pressure-repetition may be a discrete pressure or a limited pressure range. Further, a maximum number of limited-pressure repetitions may be established, after which the entire pressure range must be repeated.

Desk drawer microfiche reader

Briefcase microfiche reader

A microfiche reader assembly especially suitable for use in a desk drawer of typical size is disclosed herein. This assembly includes a housing, a projection screen, a microfiche support arrangement for supporting a microfiche for movement within a given rectangular operating area and an optical arrangement cooperating with the supported microfiche for projecting an enlarged image of a section of the microfiche on to the screen when the microfiche is in its operating area. While this assembly requires more room than the standard desk drawer allots during use, it is made sufficiently collapsible to fit entirely within the confines of the drawer when not in use so as to allow the drawer to be closed. However, at the same time, the assembly is expandable for use within the drawer when the latter is opened, whereby the assembly does not have to be removed.

Collapsible microfiche reader assembly especially suitable for use in a

A microfiche reader is disclosed herein and includes an assembly for supporting a microfiche in a given area, a projection screen and an optical arrangement for providing an image of a segment of the microfiche on the screen. This arrangement utilizes a dual projection lens assembly and a dual condenser lens assembly which cooperate with one another so that the magnification of the projected image can be easily varied between two levels. As disclosed, the dual projection lens assembly itself includes two distinct projection lenses which are contained in collapsible housings. Moreover, each of these latter lenses is adjustably focused by rotational movement of its associated housing and remains in the focusing position selected unless its housing is again rotated.
