Abstract: A method is disclosed for diagnosing, monitoring and treating cardiovascular pathologies. Among the hemodynamic parameters of interest are peripheral resistance, compliance, and cardiac (left ventricular) output. Peripheral resistance determined according to the present invention has been found to be a reliable indicator, not only of hypertension, but also of the cause of the hypertension. The determined peripheral resistance can be compared against a predetermined threshold value. This comparison helps to foster a diagnosis of a hypertensive condition.

Abstract: A multi-piece, low profile microelectronic connector having a simplified, "snap-together" construction requiring no lead carrier. One or more electrical components are located within a rear connector body element, which mates with a front connector body element upon assembly. The leads of the rear body element are shaped so as to cooperate with a series of contour elements ("bumps" in one embodiment) formed inside the plug receptacle cavity in the front connector body element. The shape of the leads and bumps provide a continuous normal force on the distal end of the leads, thereby maintaining them in contact with the corresponding leads of the modular plug. In a second aspect of the invention, a series of mounting pins are provided to permit tandem mounting of multiple connectors to an external device using a minimum number of mounting holes, and maintaining a minimum lateral connector width. A method of manufacturing and assembling the aforementioned connector is also disclosed.

A non-conducting base member having a plurality of electronic element barriers and wire lead through-holes is provided. The through-holes are generally located within the interior regions of the base element to minimize potentially detrimental field interactions or capacitive coupling between the leads and the external package terminals.

Abstract: A modular telephone plug comprises a one piece insulation housing having a hollow body with two portions, and plural contacts mounted at one end or tip thereof. A first portion accommodates a cable having an outer insulation jacket enclosing a number of individual conductors. A second portion is directly beneath the contacts. A sleeve accommodates untwisted ends of individual conductors extending from the outer insulation jacket. The sleeve is configured to be placed into the second portion to facilitate successful electrical termination of the contacts with the individual conductors accommodated within the sleeve. The sleeve enables shortening of untwisted conductor length used in the connector to a short length, such as in a range below 8 mm and preferably approximately 5 mm, to reduce Near End Cross Talk (NEXT) when data is transmitted by means of the telephone plug, particularly for connectors of Category 5 and higher.

Abstract: A microelectronic component carrier package and method of its manufacture. A non-conducting component carrier having vertical risers and guide channels permits the rapid and accurate routing of microelectronic component leads with respect to the leadframe. Specially shaped perforations in the leadframe adjacent to and aligned with the guide channels receive the leads, strip away the necessary amount of insulation, and sever the leads to the proper length in one manufacturing process step. The leads are joined to the leadframe by an interference fit, conventional bonding technique (such as solder or thermal compression bonding), or other techniques. The perforations further provide for stress relief of the leads in the assembled package, and permit the joints between the leadframe and leads to reside outside of the package, thereby minimizing the overall volume of the package.

A bobbin winding is positioned within a cavity defined by the toroidal channels of the base and cover members with a core comprised of the central posts of the base and cover member positioned within an opening in the bobbin winding.

Abstract: An electronic fail safe circuit ensures that if there is a microprocessor failure during a brake application, this failure does not result in a release of the brakes. This is accomplished by the fail safe circuit forcing the appropriate solenoids to the self-regulating valve's hold state for a certain amount of time. This, in combination with the self regulating valve, accomplishes the desired outcome of a minimum disruption in the brake application and, specifically, prevention of an erroneous brake release. To further enhance the reliability of the system, a dual battery power supply is used. Each battery is tested prior to doing a brake application. Each battery has to pass the test, i.e., each battery individually must have enough charge to complete the brake application, before the brake application is undertaken.
