Abstract: A pager-based alert system includes a monitor center that is in telephonic or data communication with a paging station allowing the command center to send multi-digit code words where selected digits comprise an address for selecting one or more of a plurality of physical units (paging receivers) and to direct the receiver to output visible and/or audible signals indicative of a particular alert condition. By providing the physical unit with graphic icons overlaying the visual indicators, an observer can readily determine the nature of the alert condition so that appropriate remedial action can be taken.

Abstract: A feed additive for dairy cattle is described comprising DHA and inhibitors of microbial degradation of DHA in the rumen of the dairy cattle. A method of producing milk in dairy cattle which is enriched for DHA is also described comprising feeding the dairy cattle a feed containing the feed additive of the invention for a period of at least about 14 day, and milking the dairy cattle to obtain milk enriched for DHA.

Abstract: This invention provides a method of detecting a high oncogenic-risk type human papillomavirus in a subject which comprises: obtaining from a subject a specimen containing cervical cells and treating the specimen so as to recover nucleic acid molecules present in the cervical cells; contacting the resulting nucleic acid molecules with multiple pairs of single-stranded labeled oligonucleotide primers capable of specifically hybridizing with a different high oncogenic-risk type of human papillomavirus; amplifying any nucleic acid molecules to which a pair of primers hybridizes so as to obtain a double-stranded amplification product and treating any double-stranded amplification product so as to obtain single-stranded nucleic acid molecules; contacting any resulting single-stranded nucleic acid molecules with multiple single-stranded labeled oligonucleotide probes which are capable of specifically hybridizing with such high oncogenic-risk types of human papillomavirus; contacting any resulting hybrids with a mark

Abstract: This invention provides a method of typing a human papillomavirus in a patient infected by human papillomavirus which comprises: obtaining a sample containing DNA from the human papillomavirus to be typed; amplifying the L1 portion of the human papillomavirus DNA; treating the resulting amplified DNA with a plurality of predetermined restriction enzymes so as to produce restriction fragments; and analyzing the fragments so produces so as to type the human papillomavirus.

Abstract: The subject invention provides a method of diagnosing congenital adrenal hyperplasia in a human subject. The subject invention also provides a method of typing a human papillomavirus in a patient infected by a human papillomavirus. The subject invention further provides a method for detecting Mycobacteria in a clinical sample. Finally, the subject invention provides a method for typing Mycobacteria in a clinical sample containing Mycobacteria.

Abstract: A live display apparatus for setting extension and flexion limits in a continuous passive motion (CPM) system. The CPM system includes a carriage for supporting a patient's limb through a range of reciprocal angular movement, a drive motor for driving the carriage, a carriage state sensor for providing a signal representative of carriage state and a control unit responsive to the carriage state sensor for controlling the drive motor. The live display apparatus includes an operator controlled extension limit select switch which is operatively coupled to the control unit. The select switch causes the carriage to be driven through its range of movement to a desired extension limit when actuated during an extension limit select mode. Data representative of the selected extension limit is stored in extension memory. An extension limit display is responsive to the control unit and provides a visual display indicative of the extension limit selected.

Abstract: Safety features for a continuous motion therapy system of the type including a carriage for supporting a patient's limb, a drive unit for driving the carriage through a range of reciprocal angular movement, first and second channel neuromuscular stimulators for applying electrical stimulation to muscles of a patient's limb, and a controller for controlling the drive unit and stimulators. Both stimulator channels must be turned OFF after the controller is powered up before either stimulator channel will operate. The drive unit is enclosed by a cover. When pressure on the cover is sensed, the controller stops and reverses the direction of the carriage. The drive unit includes a drive motor which is coupled to the carriage by a linkage. Limit switches provide limit signals when the linkage reaches predetermined limit positions. In response, the controller stops and reverses direction of the carriage.

Abstract: An ultraviolet light sensitive emulsion material, which becomes transparent to the user only after the ultraviolet light sensitive emulsion material is exposed to a predetermined amount of ultraviolet light, to expose a colored backing surface to view. In one form of the invention, an ultraviolet light inhibiting material is disposed in covering or blocking relationship relative to the emulsion material arranged in a graduated pattern of varying opacity, for inhibiting passage of ultraviolet light selectively to the ultraviolet light sensitive emulsion material to enable the emulsion to be rendered transparent in a series of graduated indications when the device is exposed to progressively longer periods of time.

Abstract: A foam polyvinyl product prepared from a composition comprising a vinyl polymer and an alkali carbonate foaming agent.

Abstract: A continuous passive motion (CPM) apparatus mobilizes the knee joint of a patient's leg. In order to achieve total extension of the leg, the CPM apparatus pauses each time the extension end position is reached. A neuro-muscular stimulator (NMS) is enabled to provide stimulation to the patient's quadriceps muscle to effect a total extension of the leg. At the end of the pause interval, the NMS turns off, and the CPM resumes motion.

Abstract: An electronic switching circuit for use in a demand-type cardiac pacer for (1) allowing the amplitude of the stimulating pulses to be selected, (2) ensuring a high input impedance for the heartbeat sensing amplifier, and (3) ensuring a low recovery time following the generation of a pacer pulse. Disposed between the heart contacting electrodes and the sensing amplifier is an electronic switch which is closed during a predetermined period (the sensing interval), but which is opened when the pulse generator is producing a pacer pulse. Thus, the sensing amplifier is shielded from receiving the high voltage surge occasioned by the application of a pacer pulse to the heart. Similarly, an electronic switching device is interposed between the pulse generator and the heart contacting electrodes, which device is closed during a pacing interval, but open during the aforesaid sensing interval, thus isolating the sensing amplifier from the pacer circuitry.

Abstract: An electrical pacer device which responds to cardiac demand so as to alter the cardiac output in a fashion to satisfy that demand. Changes in the fundamental period of the atrial electrical cycle are detected and averaged over a predetermined time interval and the resulting control signal is used to raise and lower the ventricular heart rate to increase and decrease the aforesaid cardiac output. At the same time, means are provided for continuously driving the ventricular rate toward a predetermined lower rate (the at rest rate) on a time cycle which is significantly longer than the above-mentioned predetermined time interval.

Abstract: A pneumatic tire pressure indicator adapted to be attached to a valve stem of a pneumatic tire for designating a low pressure condition therein includes a member defining at least one window in a housing, and an attention-attracting member mounted on the housing out of proper orientation relative to the window to conceal the attention-attracting member from view when normal air pressure exists within the tire. A mechanism rotates the members relative to one another to properly orient them to expose the attention-attracting member through the window for indicating purposes when the tire pressure falls below a predetermined value. A sensing mechanism activates the rotating mechanism when the pressure within the pneumatic tire falls below the predetermined value.
