International Classification:

H01L 3300

US Classification:

257 94, 257 96, 257103, 257190

Abstract:

A smoothing structure containing indium is formed between the substrate and the active region of a III-nitride light emitting device to improve the surface characteristics of the device layers. In some embodiments, the smoothing structure is a single layer, separated from the active region by a spacer layer which typically does not contain indium. The smoothing layer contains a composition of indium lower than the active region, and is typically deposited at a higher temperature than the active region. The spacer layer is typically deposited while reducing the temperature in the reactor from the smoothing layer deposition temperature to the active region deposition temperature. In other embodiments, a graded smoothing region is used to improve the surface characteristics. The smoothing region may have a graded composition, graded dopant concentration, or both.

International Classification:

A61F 2/06

US Classification:

623 111

Abstract:

An intravascular delivery catheter includes a middle member or manipulator to ameliorate the effect of buckling of the graft cover during the tracking or positioning of the delivery device within a body flow lumen to deploy an exclusion device, such a stent graft. The delivery device/catheter includes a region or regions of lower resistance to bending than other portions of the delivery device, which are positioned, within the delivery device, to preferentially bend the delivery system at locations where buckling will have minimal effect upon the deployment of the exclusion device from the delivery system. The preferential bending is accomplished, by providing a middle member/manipulator that is a rod with laterally oriented slots, having different depth and spacing configurations, or by using a wire coil as a portion of the middle member where the variable stiffness is created either by providing a variable/multiple coil diameter or by using a wire having a variable diameter along its length while the wire coil diameter is relatively uniform.

Abstract:

III-Nitride light emitting diodes having improved performance are provided. In one embodiment, a light emitting device includes a substrate, a nucleation layer disposed on the substrate, a defect reduction structure disposed above the nucleation layer, and an n-type III-Nitride semiconductor layer disposed above the defect reduction structure. The n-type layer has, for example, a thickness greater than about one micron and a silicon dopant concentration greater than or equal to about 10cm. In another embodiment, a light emitting device includes a III-Nitride semiconductor active region that includes at least one barrier layer either uniformly doped with an impurity or doped with an impurity having a concentration graded in a direction substantially perpendicular to the active region.

International Classification:

H04L 29/06

US Classification:

709227

Abstract:

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for conducting and scheduling a communication session with a remote agent. A communication session can be scheduled using a scheduling interface configured to present scheduling data. Upon scheduling a communication session, the user can be sent a confirmation message including the details of the scheduled communication session. The user can enter the communication session via a launch page configured to allow entrance to the communication session during a scheduled time period. Prior to the time period, the launch page can present the user with a clock indicating the remaining time until the user can enter. Upon entering the communication session, the user is presented with a communication session interface enabled with a primary communication method. Communication methods can be added or terminated with terminating the communication session as long as one communication method remains active.

Abstract:

The present disclosure generally relates to user interfaces for managing locks. In some examples, an electronic device displays user interfaces for configuring a lock accessory device based on detected features of the lock accessory device, such as a short-range communication user interface for enabling an express mode of the lock accessory device and/or a pin user interface object for enabling a code for accessing the lock accessory device. In some examples, an electronic device displays a user interface corresponding to a respective user of a home automation system that includes statuses indicating whether the respective user has access to a plurality of lock accessory devices of the home automation system.

Abstract:

A steerable illumination fixtures include an emitting source and a refractive optical system that steers an emitted beam by relative translation of the emitting source against the optical system. The light emitting source may be placed along an optical axis of one or more lenses to produce an output beam along that axis, or translated in-plane (orthogonal to the optical axis) relative to the lenses to produce a steered beam. The optical system may include refractive lenses and in some embodiments mixing channels and/or one or more baffles with apertures. The design is typically optimized to produce a round, uniform beam that retains approximately the same power level and beam width as it is steered. It is beneficial, but not required, that a second lens have a diameter equal to or larger than a first lens. The lenses may be configured so that the effective focal plane of the two lenses together is located approximately at the plane of the light emitting source.
