Abstract: Button functionalities for user interfaces, e.g., for use with a portable multifunction device, are disclosed. Exemplary button functionalities are described for an electronic device with a display, a rotatable and depressible input mechanism, and/or a button. Different device features may be accessed, depending on whether the rotatable and depressible input mechanism or the button is activated, and further depending on whether the activation represents a single press, a double press, or an extended press on the rotatable and depressible input mechanism or the button.

Abstract: The present disclosure introduces, among other things, an electronic device, e.g. an integrated circuit (IC). The IC includes a semiconductor substrate comprising a first doped layer of a first conductivity type. A second doped layer of the first conductivity type is located within the first doped layer. The second doped layer has first and second layer portions with a greater dopant concentration than the first doped layer, with the first layer portion being spaced apart from the second layer portion laterally with respect to a surface of the substrate. The IC further includes a lightly doped portion of the first doped layer, the lightly doped portion being located between the first and second layer portions. A dielectric isolation structure is located between the first and second layer portions, and directly contacts the lightly doped portion.

Abstract: An impeller for a centrifugal blast wheel machine includes a hub provided at one end of the impeller, with the hub being configured to be coupled to the motor. The hub further includes a ring provided at an opposite end of the hub, with the ring defining a media inlet to receive blast media. The impeller further includes a plurality of cylindrical vanes positioned between the hub and the ring. The plurality of cylindrical vanes is spaced from one another on peripheries of the hub and the ring. The plurality of cylindrical vanes defines a plurality of impeller media outlets constructed and arranged to allow egress of blast media upon rotation of the impeller.

Abstract: A radiopaque marker that includes a body being adapted to be disposed around a portion of an implantable medical lead and formed from a polymer mixed with a radiopacifier. The polymer is designed to form a symbol that identifies the implantable medical lead as being designed for safe application of a medical procedure. In some instances, the body of the radiopaque marker includes portions of varying thicknesses, the thick portions of the body being designed to form the symbol that identifies the implantable medical lead as being designed for safe application of a medical procedure such that the thick portions of the body appear more radiologically dense during an imaging procedure. In other instances, the body of the radiopaque marker may have a relatively uniform thickness and is shaped into the symbol that identifies the implantable medical lead as being designed for safe application of a medical procedure.

Abstract: A radiopaque marker may include a body formed of a polymer and being adapted to be disposed around a portion of an implantable medical lead and a symbol formed of at least a radiologically dense powder or liquid added to the body and designed to identify the implantable medical lead as being safe application of a medical procedure. In some instances, the symbol may be formed of a polymer mixed with the radiologically dense powder or liquid. The body may also be formed of a polymer mixed with a radiologically dense powder or liquid wherein the mixed polymer forming the symbol is radiologically denser than the mixed polymer forming the body.
