Abstract: A multipole permanent magnet may be provided with a magnetic-field shunt. The multipole permanent magnet may be formed from compression-molded magnetic particles such as magnetically anisotropic rare-earth particles in an elastomeric polymer. The magnetic-field shunt may be formed from magnetic members in a polymer binder that are separated by gaps to allow the shunt to flex or from magnetic particles in a polymer binder. The magnetic particles in the polymer binder may be ferrite particles or other magnetic particles. The polymer binder may be formed from an elastomeric material and may be integral with the elastomeric polymer of the multipole permanent magnet or separated from the elastomeric polymer of the multipole permanent magnet by a polymer separator layer. Conductive particles may be formed in polymer such as the elastomeric polymer with the magnetic particles. The conductive particles may be configured to form electrical connector contacts and other signal paths.

Abstract: Keyboards and other electronic input devices have a key or keys with glyphs that are invisible to an unaided human eye in a first condition, such as when an underlying display attached to the key is not emitting light. The glyphs are visible through the key or keys when the display emits light. A one-way visibility layer or structure obscures the visibility of the display when viewed from above, but when the display emits light, the light penetrates through the one-way visibility layer, such as by passing through an array of microperforations in the key, and is visible to an onlooker.

Abstract: An electronic device may include intertwined strands of material such as strands forming fabric. A strand in the fabric may include a light-emitting core surrounded by a coaxial light modulator layer. The light-emitting core may be formed from an optical fiber, light-emitting diodes mounted to a polymer core, or a layer of light-emitting diodes sandwiched between coaxial inner and outer conductive layers. The light modulator layer may have coaxial transparent inner and outer electrodes and may have a light modulating material such as electrochromic material, liquid crystal material, or other material that exhibits optical properties such as color and/or light transmission that can be electrically controlled.

Abstract: A housing made from a circuit laminate includes first and second layers coupled together. Each includes a rigid, electrically insulating non-planar structural layer, flexible conductive traces disposed on surfaces of the structural layer, and flexible connector layers contacting to the flexible conductive traces. The housing may be formed from the circuit laminate using thermoforming or another process that co-molds the first and second layers. The structural layers stiffen the housing and/or form an environmental or other barrier so that the housing protects an internal component.

Abstract: A method and system for observing and monitoring thermal characteristics of a machining operation, such as a surface finishing operation, performed on a workpiece is disclosed. The surface finishing operation can be performed on the workpiece in order to remove a surface defect, e.g. a parting line, on a surface of the workpiece and/or to provide a mirror-like finish to the workpiece. In one embodiment, an emissive layer is applied to the workpiece to increase a thermal emissivity of the workpiece. In some embodiments, a finishing surface, such as a polishing or buffing wheel, and/or a lubricant used in a finishing operation is monitored. A thermal profile of the surface of the workpiece, finishing surface and/or lubricant can be obtained. The finishing operation can be modified in response to the monitored thermal characteristics to prevent the occurrence of defects and improve the efficacy of the finishing operation.

Abstract: Laminate components for electronic devices are disclosed. The electronic device may include a housing having a laminate structure. The laminate structure may include a first layer defining a front surface of the housing, a second layer defining a rear surface of the housing, and at least one intermediate layer positioned between the first layer and the second layer. The layers of the laminate may be configured to allow another component to be embedded in the housing, to provide an attachment feature, or to provide a reinforcing feature.
