Abstract:
Systems and methods for deriving and modifying personal preferences related to at least one controllable lighting network are disclosed. The systems include a processor that can be used in conjunction with a personal communication device and a preferences database. The processor is used to detect an identifier for a user, a plurality of adjustments to the at least one controllable lighting network requested by the user, and a context corresponding to each of the plurality of adjustments. The processor in some such systems has an associated local memory to store the plurality of adjustments, corresponding contexts, and the identifier of the associated user. The processor is further used to analyze the plurality of lighting adjustments and the corresponding contexts. Based on the analysis, the processor identifies a correlation between the plurality of adjustments and the contexts, and create at least one personal preference rule associated with the user identifier based on the correlation. The preferences database in some such systems is used to store the rules and the plurality of adjustments.

In accordance with certain embodiments, a phosphor element at least partially surrounding a light-emitting die is shaped to influence color-temperature divergence.
Abstract:
In various embodiments, an illumination system includes multiple light-emitting strings that are selectively activated or deactivated to regulate an overall output of the array.
Abstract:
In accordance with certain embodiments, a semiconductor die is adhered directly to a yielding substrate with a pressure-activated adhesive notwithstanding any nonplanarity of the surface of the semiconductor die or non-coplanarity of the semiconductor die contacts.
Abstract:
In various embodiments, a lens array comprises a plurality of aspheric lens elements each optically coupled to a light-emitting element and producing an out-of-focus image thereof. The images combine to generate a target luminous intensity distribution, e.g., providing constant illuminance on a plane.

Abstract:
Systems and methods for managing interaction with controllable lighting networks are disclosed. Particularly, a user's input regarding the user's preferred level of interaction with a controllable lighting network is used in conjunction with memories and processors, to selectively allow the controllable lighting network access to the user's personal data such as the user's identity or the user's personal lighting preferences. A user's preferred level of interaction with a controllable lighting network is also used, in conjunction with personal mobile electronic communication devices, to allow the user to control lighting within controllable lighting networks.
Abstract:
A transfer stamp that can be charged with a spatial pattern of electrostatic charge for picking up selected semiconductor dice from a host substrate and transferring them to a target substrate. The stamp may be bulk charged and then selectively discharged using irradiation through a patterned mask. The technique may also be used to electrostatically transfer selected semiconductor dice from a host substrate to a target substrate.
Abstract:
