Abstract: A system such as a vehicle, building, vessel, aircraft, or electronic device system may have a layer of material with invisible laser-drilled openings. The layer of material may include an outer layer of fabric overlapping an inner layer such as an inner foam layer. Laser-drilled openings may include outer openings in the fabric layer and inner openings in the foam layer. Each of the inner openings may be overlapped by multiple outer openings. The exposed surface of the fabric layer may have strands of material of different appearances and/or may otherwise be configured to help visually hide the laser-drilled openings. Laser-drilled openings may also have small sizes to help make the laser-drilled openings invisible. Laser-drilled openings may overlap components such as audio components, heating and cooling components, and/or light-emitting components.

Abstract: Three-dimensional weaving, knitting, or braiding tools may be used to create three-dimensional fabric (24) with internal pockets (56). The pockets (56) may be shaped to receive electrical components such as switch electrodes (46A, 46B) for a switch (18). The fabric (24) may have adjacent first and second layers that are interposed between the switch electrodes (46A, 46B). The switch electrodes (46A, 46B) may be biased apart using magnets (46A-1, 46B-1) or other biasing structure. In a region of the fabric (24) that overlaps the first and second switch electrodes (46A, 46B), the first and second layers of fabric may be disconnected from each other. This allows the first and second layers to pull away from each other so that the electrodes (46A, 46B) are separated by the biasing force from the biasing structure. The switch (18) can be closed by pressing the electrodes (46A, 46B) together.

Abstract: An accessory device for use with an electronic device is disclosed. The accessory device may include multiple layers. One layer may be formed from a plastic. Other layers may include a fabric layer and a silicone layer. The accessory device may further include a retaining feature designed to hold or carry an object, such as a stylus for use with the electronic device. The accessory device may include a recessed region suited to receive the retaining feature. This allows the retaining feature to be stored in the accessory device when the retaining feature is not in use. Further, the retaining feature may be co-planar with an interior region of the accessory device such that the electronic device is not disturbed when positioned in the accessory device. In this manner, the retaining feature may be hidden. Also, the retaining feature may be deployed from the recessed region and receive the object.

Abstract: Heat transfer systems for maintaining a thermal balance between a gas turbine engine and heat generating accessory components of the engine are disclosed. In the embodiment illustrated, heat is removed from the cooling system 48 of an electrical generator 46 and is transferred to the fuel supply system 32 of the engine. In one detailed embodiment, the cooling system 48 is in direct heat transfer communication with the downstream portion 62 of the fuel supply system through a heat exchanger 76 and in indirect heat transfer communication with the upstream portion 60 of the fuel supply system through the fuel recirculation system 42.

Abstract: A structure and method for providing cooling fluids from a compression section 10 to a turbine section 14 of an axially flow rotary machine is disclosed. Various construction details and steps of the method enable the machine to minimize the effect that unscheduled variations in the temperature of the cooling fluids have on operating clearances in the turbine section. These unscheduled variations may result from changes in ambient temperature and component deterioration. An internal cooling fluid from the discharge region 52 of the rearmost compressor 18 is used to modulate the flow of a second fluid impinged on the exterior of the outer case 24 for controlling the clearance between an array of rotor blades 26 and a coolable stator shroud 64 spaced radially outwardly of the rotor blades. In one embodiment, a valve 32 for modulating the flow of the second fluid has at least one thermostatic bimetallic spring 86 for transducing a change in temperature into a displacement.

Abstract: A cooling system 44 for an electrical generator 42 is disclosed. The cooling system rejects excess heat to the engine fuel through a primary heat exchanger 46 and at low fuel flow rates, supplementarily rejects heat to fan air at a secondary heat exchanger 48 located remotely from the fan duct 30. In one embodiment, the secondary heat exchanger is disposed in a nacelle fan compartment 14. In another embodiment, the secondary heat exchanger is disposed in a nacelle core compartment 16.
