Abstract: The present disclosure generally relates to a robotic gripping system and method that utilizes vacuum suction and finger grasping, wherein the suction and grasping are actuated based on a dynamic collision model. In an exemplary embodiment, the present disclosure is directed to generating collision scenes of a surrounding environment which is used to determine possible collisions in a motion path, and which is used to selectively actuate the vacuum suction and/or finger grasping.

Abstract: A robotic manipulator includes a first stage, a second stage, a third stage, and an actuator that actuates movement of the second stage with respect to the first stage. Movement of the second stage with respect to the first stage passively drives movement of the third stage with respect to the second stage. In some embodiments, the passive driving is achieved using one or more cables. In other embodiments, the passive driving is achieved using rack and pinion components. The robotic manipulator may further include additional stages, wherein movement of preceding stages passively drives movement of succeeding stages.

Abstract: An apparatus for use with a robot may couple to or form part of an appendage, for example a wrist. The apparatus can include a base, a first platform, a second platform, a first set of linear actuators that moveably couple the first platform to the base and a second set of linear actuators that moveably couple the second platform to the first platform. The apparatus can take the form of dual prismatic platforms. A controller can provide control signals to operate the linear actuators to cause the first platform to translate and rotate with respect to the base and to cause the second platform to translate and rotate with respect to the first platform. Connectors can couple the base to an appendage and couple an end effector to the second platform.

Abstract: A chain and a chain and sprocket assembly for a roller, bush, or inverted tooth chain is disclosed. The chain has at least two types of link plates having different profiles, with at least one type of link plate having a leading corner for interaction with a contact ring on the sprocket, thereby reducing noise by reducing chordal action and by breaking up the regular timing of roller-sprocket (or bushing-sprocket) and link plate-sprocket impact. A method of reducing noise in a chain and sprocket assembly is also disclosed.

Abstract: A central service facility is connected via a network and a uniform service interactive platform to a multiplicity of remotely located medical diagnostic systems. The interactive platform includes a video/audio plug-in application which can be used to access a library of videos via a network. The video library is stored at the central service facility or on a local area network at the remote facility. The interactive platform of the medical diagnostic system comprises a web browser which enables the end-user to search and select a training video from the database, and a video/audio player for viewing the selected video directly from the operator's console. Depending on bandwidth availability, the video file can be downloaded to the remotely located medical diagnostic equipment prior to display or streamed in real-time.

Abstract: Novel methods for reliably and reproducibly forming magnetic tunnel junctions in integrated circuits are described. In accordance with aspects of the invention, sidewall spacer features are utilized during the processing of the film stack. Advantageously, these sidewall spacer features create a tapered masking feature which helps to avoid byproduct redeposition during the etching of the MTJ film stack, thereby improving process yield. Moreover, the sidewall spacer features may be used as encapsulating layers during subsequent processing steps and as vertical contacts to higher levels of metallization.

Abstract: A silent chain and sprocket assembly is disclosed for use with a chain tensioner that provides driving contact on both sides of the chain and improved system wear, noise and vibration characteristics without adding to the chain's weight or material costs. The front-side sprockets employ sprocket teeth and engage the front-side silent chain links in conventional fashion. The back-side driven sprockets differ from prior silent chain sprockets in that the sprockets employ small protrusions instead of traditional teeth. The silent chain engages a back-side sprocket protrusion using the geometry of either a single link, or that of two adjacent links, as the chain wraps on the back-side sprocket.

Abstract: A system is provided for remotely servicing medical diagnostic systems. The diagnostic systems may include a range of modalities and system types. A remote service facility may be contacted by the diagnostic systems, or may contact the diagnostic systems via a network link. Service requests, messages, protocols, data and log files, and so forth, may be transmitted between the diagnostic systems and the service facility. The service requests are handled by the service facility interactively with the medical diagnostic systems. The diagnostic systems are thereby apprised of the status of service requests, service reports, and so forth. A uniform interface and platform are provided for facilitating interactive communications of service requests and data between the diagnostic systems and the service facility.
