Appl. No.:

13/491335

Inventors:

Christopher Bower - Raleigh NC, US
Joseph Carr - Chapel Hill NC, US

International Classification:

G03F 7/20
B29C 59/00

Abstract:

A method for fabricating a substrate having transferable chiplets includes forming a photo-sensitive adhesive layer on a process side of a source substrate including active components or on a patterned side of a transparent intermediate substrate. The intermediate substrate is brought into contact with the source substrate to adhere the active components on the process side to the patterned side of the intermediate substrate via the photo-sensitive adhesive layer therebetween. Portions of the source substrate opposite the process side thereof are removed to singulate the active components. Portions of the photo-sensitive adhesive layer are selectively exposed to electromagnetic radiation through the intermediate substrate to alter an adhesive strength thereof. Portions of the photo-sensitive adhesive layer having a weaker adhesive strength are selectively removed to define breakable tethers comprising portions of the adhesive layer having a stronger adhesive strength. The breakable tethers physically secure the active components to the intermediate substrate.

Abstract:

Coordination of a plurality of resources is disclosed to respond to a local service target. A local measurement is taken by a first resource and, if the first resource cannot satisfy the local service target, short range recruitment of one or more additional resources is performed by providing a first signal to a cluster of resources associated with the first resource. If the short range recruitment does not satisfy the local service target, a second signal is provided to a network resource controller for long range recruitment of one or more resources to satisfy the local service target.

Abstract:

Architectures, apparatuses, methods, systems, and techniques for controlling electrical power distribution network are disclosed. Distributed, hierarchical controls including layered locational energy service control variables may be utilized to determine and control the provision of energy services, including real power, reactive power (VAR), and capacity reserves, by DERs in a distribution network. In a first ex-ante iteration a simulation may be performed to calculate a set of subnetwork-specific control variables based on subnetwork locational energy service prices and a plurality of sets of DER-specific control variables based on DER locational energy service prices. In a second ex-ante iteration a set of actual subnetwork-specific control variables based on subnetwork locational energy service prices and a plurality of sets of actual DER-specific control variables based on DER locational energy service prices. Provision of energy services by DERs in a distribution network occur in response to the determined control variables.

Abstract:

A method for a building automation system to control a comfort level in a building includes tracking a building occupant's activity data using a wearable activity tracker. A smartphone is coupled to the wearable activity tracker. Activity data is collected from the wearable activity tracker using a smartphone app operating on the building occupant's smartphone, and a comfort value is determined using the smartphone app based on the activity data. A report of the comfort value is transmitted to a building automation system (BAS) app from the smartphone, and the output of a building system is controlled based on the comfort value.

Abstract:

A method for controlling a temperature of a building using a building thermal model of the building in a model predictive control (MPC) system includes measuring the temperature and a rate of change of temperature for at least one zone that is included in the building thermal model so as to determine an error from a temperature and rate of change of temperature that is predicted by the MPC system. Possible causes of the error and a probability of each of the possible causes of error occurring are determined. An impact of each of the possible causes is evaluated so as to identify at least one of the possible causes which would reduce the error. The building thermal model is adapted based on the at least one identified possible cause and the temperature of the building is controlled using the adapted building thermal model in an MPC controller.

H01L 31/043

Abstract:

An optical data communication and power converter device includes a receiver circuit comprising an optical receiver. The optical receiver includes a photovoltaic device and a photoconductive device arranged within an area that is configured for illumination by a modulated optical signal emitted from a monochromatic light source of a transmitter circuit. The photovoltaic device is configured to generate electric current responsive to the illumination of the area by the modulated optical signal. The photoconductive device is configured to generate a data signal, distinct from the electric current, responsive to the illumination of the area by the modulated optical signal. A reverse bias voltage may be applied to the photoconductive device by the photovoltaic device, independent of an external voltage source. Related devices and methods of operation are also discussed.

Abstract:

A wind turbine is disclosed having a generator and rectifier and structured to provide direct current power that in one form is medium voltage direct current (MVDC). The wind turbine includes a crowbar circuit arranged to protect from a condition such as an overvoltage. The crowbar can be activated based on a voltage measurement or rate of change of voltage. A resistor can be coupled to the crowbar to absorb excess power provided by the generator during the overvoltage condition. Individual wind turbines in a wind farm can each have individual crow bars that can be activated based on local measurement of a voltage condition. In some forms the crowbar can be coupled with a transformer, for example coupled with a tertiary winding of a three winding transformer.
