Abstract: A diaphragm pump having a crankshaft that is rotatable about a rotational axis and coupled to a piston. The piston is reciprocally displaceable within a piston cylinder along an axis of motion between suction and discharge strokes. A diaphragm housing coupled to the piston cylinder at least partially defines a pumping chamber through which fluid is pumped as the piston reciprocates. The axis of motion, which intersects a connection between the piston and the connecting rod, may not intersect the rotational axis of the crankshaft such that, relative to an arrangement in which the axis of motion does intersect the rotational axis, a peak magnitude of piston side load forces during the discharge stroke is reduced and a peak magnitude of piston side load forces during the suction stroke is increased so as to attain an improved balance between the peak magnitudes of piston side load forces of the discharge and suction strokes.

Abstract: An ultrasonic transducer and generator (TAG) assembly of a surgical instrument includes generator components and transducer components. The generator components are disposed within a first cavity cooperatively defined by a body portion and a cover. The generator components are covered in a thermally insulative material. The transducer components are disposed within a second cavity cooperatively defined by a proximal housing and a spinner housing.

Abstract: Disclosed herein are methods of making a mold for use with cells, such as engineered tissue. The method includes printing a 3D printed resin mold, casting a hydrogel over the 3D printed resin mold to create a crosslinked hydrogel negative mold, and casting a silicone rubber elastomer over the hydrogel negative mold to create a master mold.

Abstract: A dust collector for use with a hand-held power tool. The dust collector includes a housing, a motor positioned in the housing, and a telescoping suction pipe coupled to the housing. The dust collector also includes a suction fan coupled to the motor and operable to generate a vacuum in the suction pipe. The dust collector further includes a dust container coupled to the housing and positioned upstream of the suction fan, and a filter at least partially arranged in the dust container. The dust collector also includes a filter cleaning mechanism including a solenoid configured to be actuated by a controller to dislodge dust from the filter when either the motor or the suction fan transitions from an active state to an inactive state.

Abstract: An surgical enclosure includes electronics including at least one visual indicator and at least a first casing component enclosing the electronics therein. The first casing component is formed from a substantially transparent material and includes a first portion and a second portion. The first portion is treated to define a first finish that reduces transparency of the first portion. The second portion defines a greater transparency relative to the first portion to enable visualization of the at least one visual indicator therethrough.

Abstract: A dust collector can be used with a hand-held power tool. The dust collector includes a housing, a telescoping suction pipe coupled to the housing, and a suction fan positioned within the housing and operable to generate a vacuum in the suction pipe. The suction pipe is configured to telescope toward and away from the housing. The suction pipe includes an outer pipe supported by the housing, and an inner pipe slidably received into the outer pipe.

Abstract: An enclosure configured to hermetically seal electronics of a surgical instrument therein includes a first casing component defining a first weld deck about a perimeter thereof, a second casing component defining a second weld deck about a perimeter thereof, and an energy director extending from the first weld deck and configured to facilitate ultrasonic welding of the first and second weld decks of the first and second casing components, respectively, with one another to establish a weld seam hermetically sealing the first and second casing components. The first weld deck lies in multiple planes.

Abstract: A dust collector for use with a hand-held power tool includes a housing, a suction pipe coupled to the housing, and an electric motor positioned in the housing. The dust collector additionally includes a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, and a depth stop assembly. The depth stop assembly is configured to limit the axial movement of the suction pipe. The depth stop assembly is configured to be alternately positioned on opposite sides of the suction pipe in a first configuration and a second configuration, respectively.

Abstract: Systems and methods for augmenting, inferring, extrapolating, deducing, reasoning, and storing logical networks of information represented in digest form are disclosed. The disclosed systems and methods enable the combined inclusion of both sensitive information and non-sensitive information into a compressed, universal, indiscernible format. Relationships can be derived or inferred between unintelligible digests of information by associating them with a common underlying entity. A universal digest format described herein may become comprehensible by further utilizing additional a priori or a posteriori knowledge of the information such that recognized digests can be utilized fully while unknown and potentially sensitive digests remain undecipherable.

Abstract: A facility for replicating offline scheduling transactions directed to a server is provided. The facility is implemented as a client-side application that integrates with and utilizes components of a store-and-forward application, which is operable to execute on a client to guarantee that transactions submitted on the client are replicated and carried out on a service hosted on a remote server even in light of intermittent connectivity between the client, the server, and networks. Records describing transactions intended remote service are written to an outbox of the store-and-forward application on the client. If the item is intended for the scheduling application, the facility is invoked by the store-and-forward application to send the item to the scheduling application. Otherwise, the facility returns the item to the outbox for processing by other components of the store-and-forward application.
