Abstract: A method and apparatus for producing blood component products. In one embodiment, a plurality of a predetermined type of blood component is harvested from a source of whole blood. At least two on-line yield determination techniques are utilized to determine the yield for the harvested blood components. One is a predetermined yield prediction technique and the second is a predetermined yield monitoring technique, each of which are individually calibrated in relation to a predetermined off-line yield determination technique. The predetermined yield prediction and monitoring techniques each provide the yield for the harvested blood components and each is then utilized to provide a determined yield. Consequently, when the harvested blood components are packaged the determined yield my be associated therewith, thereby providing a blood component product.

Abstract: A method and system for presenting time-based, comparative, patient-specific ECG data in various presentation formats, wherein color-coding is employed as a visual device to communicate vividly different, selected “changed” characteristics in that patient's current ECG-detected status.

Abstract: A method and system for diagnosing left ventricular hypertrophy (“LVH”) based on ECG data. An LVH system provides an indication of the likelihood that a patient has LVH based on an analysis of the patient's ECG data. The LVH system estimates the left ventricular mass index (“LVMI”) for the patient based on gender-specific formulae that use time-voltage data derived from the ECG data. After the LVH system calculates the estimated LVMI for the patient, it then classifies the estimated LVMI to indicate the likelihood that the patient has LVH. The LVH system may then select various statements of condition and rationale based on the patient's classification.

Abstract: A method for differentiating acute myocardial infarction (AMI) from other ECG abnormalities. The method is performed by modeling selected ECG confounders that tend to obscure AMI evidence in the ECG waveform, and by purging a subject's ECG waveform of the effect(s) of these confounders through linking selected confounder models with an appropriate, computer-implementable purge algorithm.

Abstract: A wheel hub (10), primarily for a wheelchair wheel, can be manually operated by rotating a cover (168) to give three different operating states for the wheel which includes the hub. In the first position, the wheel is free to rotate relative to the chair. In the second position, the wheel is locked to the chair, i.e. the chair is braked. In the third position, the wheel can turn in the direction corresponding to forward motion of the chair, but cannot rotate in the opposite direction. This prevents the wheelchair from undesired backward rolling movement.

Abstract: A multi-feature stroller (100) includes several unique features. The stroller, which has a forward sub-frame (104) and a rearward sub-frame (108) that is foldable upon itself, provides a napper bar (150) which extends outwardly from the forward sub-frame (104). The napper bar (150) provides a locking mechanism (254) which engages one of two locking tongues (190) extending from an underside of a car seat (160). Accordingly, the car seat (160) may be carried by the stroller (100) in a forward-facing position and a rearward-facing position. The napper bar (150) is moveable between an extended position and a recessed position by actuating a release mechanism (302). A fold down mechanism (130) is connected between the rear sub-frame (108) and the forward sub-frame (104) when actuated causes the sub-frames to fold into a collapsed position and simultaneously causes the napper bar to fall to its recessed position.

Abstract: A system is provided for filling a gap between adjoining coplanar first and second sheet members mounted on an outer surface of a common substrate and having juxtaposed first and second edge surfaces. A permanent gap filler member of predetermined shape and size intended for eventual permanent reception in the gap is employed for partially filling the gap. A temporary gap filler tool which includes a substitute gap filler element having substantially the same predetermined size and shape of the permanent gap filler member, has an abutting surface for contiguous engagement with the first edge surface of the first sheet member when advanced to an attached position before the permanent gap filler member is mounted in the gap, a minor gap surface facing opposite said abutting surface, and means for releasably attaching the temporary gap filler tool to the first sheet member. A minor gap is thereby defined between the temporary gap filler element and the second edge surface of the second sheet member.

Abstract: A rotary machine has two rotors (16,18) mounted for rotation on parallel axes, each in one of two intersecting cylindrical chambers (12,14). The rotor (16) has a hub (24) and a flap (26) extending radially from the hub into close proximity with, but not into contact with, the cylindrical wall of chamber (14). The rotor (18) has a hub and a radial recess (30) which accommodates the flap (26) as the rotors rotate. The rotors are linked to one another so that they rotate at the same angular speed but in opposite angular directions. The flap (26) divides the chamber (14) into two volumes, one either side of the flap. Working fluid is introduced through the first rotor and passes along a radial passage through the rotor to direct incoming working fluid from one side of the flap. into a volume on one side of the rotor. The working fluid can be provided from an external combustion chamber.

Abstract: An apparatus, system, and method for treating body tissue using controlled application of heat includes a control unit providing electrical power to a bipolar electrode positioned within an expandable member filled with conductive fluid. Electrical power applied to the bipolar electrode by the control unit causes current to pass from the active electrode, into the conductive fluid, and to the return electrode, thereby heating the conductive fluid. The temperature of the conductive fluid is monitored by the control unit, and power is increased and decreased in accordance with a comparison of the monitored temperature against the desired temperature range. The control unit also includes a pressure sensor for regulating the pressure in the bladder. Pressure and temperature displays and other operator controls are located on the control unit.

Abstract: The disclosed invention is a photoelectric sensor that is capable of resolving difficult low contrast sensing tasks by adjustment of the sensor's light source intensity, so as to prevent dark state saturation and extend the overall dynamic range of the sensor. The photosensor utilizes an enhanced dynamic (EDR.TM.) control circuit that combines the light source and offset adjustment of the DC amplifier circuit in a closed loop configuration. This connection provides an automatic reduction in the light source intensity as required to avoid saturation. Further, this is accomplished without sacrificing amplifier gain, so that the dynamic operating range of the photosensor is extended to include proper operation at very bright light levels. The EDR control circuit also includes an indicator circuit that is connected to the light intensity control circuit.
