Abstract: An occlusion device includes a balloon and a catheter. The occlusion device is configured to allow blood to pass through the balloon, instead of around the balloon. By allowing the blood to pass through the balloon, constant traction against the vessel wall is achieved, regardless of flow rate, thereby mitigating distal migration. The balloon includes an orifice to allow blood flow through the balloon. The orifice is independent of the diameter of the vessel, therefore the effect of the diameter of the vessel changing during the procedure will not affect the flow rate of blood. The occlusion device enables finer titration of blood flow by varying the size of the orifice when compared to conventional solutions.

Abstract: A rotor assembly for a peristaltic pump is provided. Each of a first pair of roller assemblies includes a first roller portion having a first diameter and a second roller portion having a second diameter. The first diameter is larger than the second diameter. Each of a second pair of roller assemblies includes a first roller portion having a first diameter and a second roller portion having a second diameter. The first diameter is smaller than the second diameter. The first and second pairs of roller assemblies are positionable around a circumference of a hub such that the first roller portion of the first pair of roller assemblies is aligned with the first roller portion of the second pair of roller assemblies and the second roller portion of the first pair of roller assemblies is aligned with the second roller portion of the second pair of roller assemblies.

Abstract: A sensor having a first electrode and a second electrode operably connected by a conduction channel, wherein a polymerase, primed template nucleic acid and nucleotide form a stabilized ternary complex that is immobilized in or on the conduction channel, whereby association and dissociation of the ternary complex is detected due to changes in electrical properties of the sensor. Identification of the nucleotide type that participates in the complex indicates the identity of the next template base in the template. Repeated cycles of extending the primer and detecting stabilized ternary complexes can allow determination of the sequence of nucleotides for the template.

Abstract: The present disclosure provides a dual-action pest control formulation for controlling rodents and arthropods, the formulation including: a rodenticide; an insecticide; an optional attractant; and a carrier matrix. The present disclosure also provides a method of controlling rodents and arthropods, the method including: applying the dual action pest formulation to a target area.

Abstract: A method and system for ultrasonically inspecting a ring gear of a gearbox is provided. The method and system can be used for the detection, characterization and/or sizing of defects in the ring gear. The ring gear has a plurality of teeth, which extend radially inward with respect to an outer surface of the gearbox. The method includes the steps of selecting an ultrasonic transducer productive of a test signal, positioning the ultrasonic transducer at an outer surface of the ring gear, orienting the ultrasonic transducer so as to direct the test signal to propagate through the ring gear, and activating the ultrasonic transducer so as to test the ring gear for defects therein.

Abstract: An authentication system and method for identifying the source of a marking formed from marking media is disclosed. A registration system preferably tags batches of marking media with taggant material and, for each batch, stores physical property information representing one or more physical properties of that batch. A source assignment system receives source identification information for each of a plurality of sources, stores the source identification information in a database and, for each source, links the source identification information with at least one batch. A source identification system comprises at least one instrument operable to provide physical property information for the media in a marking. The identification system also includes an analysis system operable to compare the physical property information for the media in the marking with the physical property information associated with batches, and to then determine whether there one or more matches of physical property information exist.

Abstract: A redundant brake control and anti-skid system is described for providing braking to a vehicle. The system includes a primary brake control assembly for performing brake control and anti-skid functions, and a secondary brake control assembly for performing brake control and anti-skid functions. A bus is provided for enabling communications between the primary brake control assembly and the secondary brake control assembly. At least one brake actuator controlled by the primary brake control assembly and at least one other brake actuator controlled by the secondary brake control assembly are included for providing braking force to wheels of the vehicle.

Abstract: A brake system and torque feedback controller is provided which utilizes low torque cutout rather than low speed cutout. The low torque cutout is further improved by gradually transitioning between torque feedback and open loop control over a range of torque. The controller allows torque compensation operation to zero wheel speed, and avoids discontinuities in braking regardless of time or torque level. The controller allows a brake to fill and engage the wheel before the full feedback signal is presented to the controller so as to eliminate the phenomena of grabby brakes.

Abstract: A brake control system which employs an antiskid control and wheel lock protection differential reference controller to provide antiskid and antilock brake control. The differential reference controller is capable of estimating both wheel velocity and vehicle velocity based on a single wheel speed sensor input. To reduce the effects of wheel speed noise, the differential reference controller estimates the wheel velocity and vehicle velocity by carrying out parallel processes using identical processing functions. The estimated wheel velocity and vehicle velocity are subtracted providing a differential output indicative of the slip velocity. Only unique parameters for each process, derived from physical constants, are different. In this way, the wheel speed noise is introduced into both processes and canceled when the results are subtracted to obtain the slip velocity.

Abstract: This invention comprises generally an integral insert for a golf shoe having several raised protuberances extending upwardly from a base shaped to fit on and cover the inner sole of the shoe. The protuberances are resilient and can be made from cellular plastic or elastomer, or can be molded integrally with the base. One protuberance tapers inwardly from the outer edge of the insert and extends from the heel to the end of the toes, and another protuberance tapers inwardly from the inner edge in the middle section.

Abstract: In a system which includes a blower for pnuematically off-loading solid particulate matter from an over-the-road carrier, such as a dry bulk tractor/trailer combination, the blower is integrated into the undercarriage of the tractor. The blower is rigidly suspended below a main frame member of the tractor by a bracket which positions the center of gravity beneath the frame member while maintaining the blower in a vertical position with respect to the undercarriage such that the lowest portion of the blower does not extend below the lowest portion of the undercarriage.
