Abstract: An electronic device may include a display system and control circuitry. The user's environment may be presented on the display system. The environment on the display system may be a captured image of the environment, may be the actual real world viewed through an optical combiner, or may be a completely virtual image representing the environment. The control circuitry may gather information about external electronic devices in the user's environment, including determining a type and location of each external electronic device and a status of wireless communications links between external electronic devices. The display system may overlay computer-generated display elements onto the user's environment to indicate the status of wireless communications links between the external electronic devices. In response to touch or gesture input, the control circuitry may send control signals to the external electronic devices to establish or break wireless communications links between external electronic devices.

Abstract: An improved differential sensor and corresponding apparatus implementing same. The differential sensor includes a substrate, an amplifier coupled to the substrate, and a plurality of highly-matched piezoelectric capacitors formed onto the substrate. A first set of the highly-matched piezoelectric capacitors are electrically coupled to a non-inverting input of the amplifier, and a second set of the highly-matched piezoelectric capacitors are electrically coupled to an inverting input of the amplifier to form an open loop differential amplifier.

Abstract: In described examples, each node between adjacent capacitive elements of a stack of series-coupled capacitive elements is biased during a reset mode, where each of the capacitive elements includes piezoelectric material. A strain-induced voltage is generated across each of the capacitive elements. Each of the strain-induced voltages is combined to generate a piezoelectric-responsive output signal during a sensing mode at a time different from the time of the reset mode.

Abstract: A fuse element strip with a central metallic section having a part with a high melting point and a part with a low melting point embedded in the high melting point part, and two lateral metallic sections with a high melting point. Each lateral section is joined to the high melting point part of the central section by a weld of fused material, and the joined sections have the same thickness so that the strip has three coplanar sections. The high melting point and low melting point parts of the central metallic section alloy at the low melting point causing the strip to melt at the melting temperature of the alloy.

Abstract: The invention relates to a fuse element consisting of a strip (10) comprising, at least, three coplanar sections having the same thickness clad-welded together, namely: a central metallic section (12) consisting of a tin core (16) and of a silver sheath (18) surrounding this core, and two lateral copper sections (14). The three sections of the strip are formed and clad-welded together by rolling.
