US Classification:

228175, 438 22, 438107, 438110, 257622, 257723

Abstract:

A self-assembly process is disclosed for integrating free standing microcomponents onto a template having a plurality of binding sites, an interconnect network, and trapping structures disposed downstream of the binding sites. The self-assembly is accomplished by flowing a fluid medium containing the microcomponents over the template such that some of the microcomponents are trapped at binding sites. The template may be simultaneously (or subsequently) heated to melt a binder such as a solder spot at each of the binding sites, and then cooled to connect the trapped microcomponents to the interconnect network. In one embodiment, removable blocking elements are disposed upstream of some of the binding sites, for example formed from photoresist. After assembling a first set of microcomponents, the blocking elements are removed, and a second set of microcomponents in a fluid medium are flowed over the template for assembly into the newly unblocked binding sites.

Abstract:

An active contact lens system () and method for fabricating an active contact lens () are disclosed. The system comprises an active contact lens () worn like a conventional contact lens, and comprising a transparent substrate () having a circuit formed of one or more of a semi-transparent display (), a display drive circuit (), a data communications circuit (), one or more biosensors (), an energy transfer antenna () and an interconnect network (). The substrate may be a conventional contact lens material, such as PMMA or RGP, and the display may be formed from a plurality LEDs. A method for fabricating the active contact lens includes fabricating the template (), forming solder compatible pads (), assembling the circuit elements () and micro-molding the lens (). The template is fabricated with an interconnect network and shape-specific recesses for receiving the circuit elements. Preferably, the assembly is done using fluidic self-assembly.

Abstract:

Disclosed are methods, devices, and systems for exchanging information between a first wearable electronic device and one of a second wearable electronic device and an account at a remote computing device associated with a user of the second wearable electronic device. The first wearable electronic device intermittently emits directed electromagnetic radiation comprising a beacon signal, and receives, via a receiver coupled to the first wearable electronic device, a signal from the second wearable electronic device identifying one of the second wearable electronic device and the account at the remote computing device. An input may then be detected at the first wearable electronic device, and in response to receiving the signal and detecting the input, the first wearable device may transmit additional data to one of the second wearable electronic device and the remote computing device associated with the second user.

US Classification:

359633, 359630

Abstract:

An image waveguide includes an in-coupling region for receiving input light into the image waveguide and an out-coupling region for emitting output light from the image waveguide. The in-coupling region includes a one dimensional array of in-coupling mirror structures orientated to reflect the input light within the waveguide towards the out-coupling region as guided light. The out-coupling region includes a two dimensional array of out-coupling mirror structures orientated to reflect the guided light out of the waveguide as the output light.

Abstract:

Devices having features deposited on two sides of a device substrate and methods for making the same. The devices are useful, for example, as the components in a macroelectronic system. In a preferred embodiment, the devices are photosensors having a plurality of electrodes patterned on a first side of the device and an electromagnetic interference filter patterned on a second side of the device. The method facilitates the fabrication of two-sided devices through the use of an immobilizing layer deposited on top of devices patterned on a first side of a device substrate; flipping the device substrate; processing the second side of the device substrate to produce patterned features on the second side of the device substrate; and releasing the devices having patterned elements on two sides of each device.

Abstract:

Disclosed are systems, methods, and devices for identifying a user associated with a wearable electronic device. First, a directed electromagnetic radiation comprising an identifier associated with a user of the wearable electronic device is transmitted to a first target device. In response, a challenge signal is received requesting a verification response verifying the authenticity of the identifier. The wearable electronic device than detects a predefined user input, and responsive to receiving the challenge signal and detecting the predefined user input, transmits a challenge response corresponding to the predefined user input to a second target device. The first and second target devices may be the same device. The predefined user input may be comprise one or more sensed head movements and/or detected user input operations.
