A heart assist system having an implantable pump conveying blood between two vascular locations and an extracorporeal system providing power and control signals to the pump. The system also includes a communication link having an implantable portion coupled to the implantable pump, an extracorporeal portion coupled to the extracorporeal system and an isolation portion between the implantable portion and the extracorporeal portion that minimizes the transmission of movement and forces from the extracorporeal portion to the implantable portion.

A bed and frame assembly includes a box that is positionable on a horizontal support surface. A pair of tracks is each of the tracks is removably disposed on the box. A lid is slidably disposed on the box for supporting a mattress. The lid is positionable in a first position to close the box or a second position to facilitate sheets on the mattress to be changed. A plurality of roller units is each disposed on the lid and rollably engages a respective one of the tracks to facilitate the lid to be rolled between the first position and the second position. A sliding unit is integrated into the box and the sliding unit is in mechanical communication with the lid. The sliding unit is actuatable in a closing condition for sliding the lid into the first position and the sliding unit is actuatable in an opening condition for sliding the lid into the second position.

A conduit for use with a blood pump can have a flared inner surface at an end of the conduit. In some embodiments, the conduit can include a strain relief member such as overmolded silicone. The strain relief member can maintain the profile of the flared inner surface. A conduit with a flared inner surface can be configured for connection to a blood pump via a connector. For example, the conduit can include an anchor member such as flange configured to engage with various components of a connector to connect the conduit to a fitting on a pump or another structure. In some embodiments, the conduit can be configured to connect to a blood conduit connector including a member such as a compression collet and a fitting such as a coupler. The connector can include a bayonet connection to facilitate rapid connection and disconnection of the conduit from a fitting.

A lawn mower includes a cutting device placed underneath a mower deck housing that surrounds the cutting device. The lawn mower further comprises a grass outlet in the mower deck housing. The outlet is leading cut grass via a discharge chute to a bag where the grass is collected. The end of the discharge chute is provided with a door that closes the discharge chute when the bag is removed from the lawn mower. The door is rotatable around an axis parallel to the axial direction of the discharge chute and automatically rotated to not cover the end of the discharge chute when the bag is secured to the lawn mower.

Various computer-implemented methods for classifying defects on a specimen are provided. One method includes assigning individual defects detected on the specimen to defect groups based on one or more characteristics of the individual defects. The method also includes displaying information about the defect groups to a user. In addition, the method includes allowing the user to assign a classification to each of the defect groups. Systems configured to classify defects on a specimen are also provided. One system includes program instructions executable on a processor for assigning individual defects detected on the specimen to defect groups based on one or more characteristics of the individual defects. The system also includes a user interface configured for displaying information about the defect groups to a user and allowing the user to assign a classification to each of the defect groups.

In one embodiment, a self-cleaning nozzle comprises a nozzle body, a sleeve surrounding a proximal end of the nozzle body, a pillar disposed within the nozzle body and a spring. The nozzle body may have a hollow cylindrical interior. The nozzle body may include an orifice formed in a distal end of the nozzle body, a shoulder formed on a proximal end of the nozzle body, and a first bearing surface on an outer lateral face of the shoulder. The sleeve may include a second bearing surface on an inner face of the sleeve and a retaining lip formed at a distal end of the sleeve. The retaining lip may define a distal end of an annular space between the sleeve and the nozzle body. The shoulder may define a proximal end of the annular space. The pillar may have a distal tip configured to interface with the orifice, thereby forming a liquid seal. The spring may be captured within the annular space, thereby biasing the distal tip of the pillar into contact with the orifice.

In one embodiment a fluid dispensing apparatus includes a first dispensing bottle configured to dispense a first liquid, a second dispensing bottle, configured to dispense a second liquid, an exterior casing. The first dispensing bottle may include a first hollow, tubular internal chamber, a first moveable piston slid ably housed within the first internal chamber, a first nozzle housing, and a first nozzle collar mounted on a top end of the first internal chamber and supporting the first nozzle housing. The first nozzle housing may include a first inlet, a first pump assembly, and a first dispensing nozzle. The second dispensing bottle may include a second hollow, tubular internal chamber, a second moveable piston slidably housed within the second internal chamber, a second nozzle housing, and a second nozzle collar mounted on a top end of the second internal chamber and supporting the second nozzle housing. The second nozzle housing may include a second inlet, a second pump assembly, and a second dispensing nozzle. The exterior casing may house the first and second internal chambers. The exterior casing may include an upper opening and a sleeve disposed thereon. The sleeve may have inner contours complementary to the first and second nozzle housings such that the first and second nozzle housings at least partially protrude through the sleeve.
