摘要:
An optical fiber includes an outer periphery formed into a shape that configures the fiber to interlock with the other fibers with complementary shapes. Methods and systems for fabricating such interlocking fibers are also disclosed. In one example, a method includes drawing a first optical fiber from a preform and forming an outer periphery of the first optical fiber into a shape that configures the first optical fiber to be interlocked with a second optical fiber comprising an outer periphery formed into a shape that is complementary to the shape of the first optical fiber.

An optical fiber includes an interlocking microstructure formed on an outer periphery of the fiber that configures the fiber to be interlocked with another optical fiber including a complementary interlocking microstructure coating.
摘要:
A system may include a first connector housing, a magnetic data storage device mechanically coupled to the first connector housing, a second connector housing configured to be mechanically engaged with the first connector housing, and a permanent magnet mechanically coupled to the second cavity. In some examples, relative motion between the magnetic data storage device and the permanent magnetic causes data stored on the magnetic data storage device to be modified. In one example, the system further includes a printed board assembly mechanically coupled to one of the first or second connector housings and a master interconnect board mechanically coupled to the other one of the first or connector housings. Modification to the data stored on the magnetic data storage device may indicate relative movement between the first and second connector housings.

摘要:
An apparatus to indicate unauthorized manipulation of at least one protected device enclosed in a housing is provided. The apparatus includes a structure attached to a first portion of the housing and a token switch attached to a second portion of the housing. The token switch is operably positioned with reference to the structure. The token switch includes a plunger, and a register programmed with a value. The register is communicatively coupled with a processor in a circuit. The circuit is communicatively coupled to drive the device. The structure, the token switch, and the circuit are internal to the housing when the housing is in a closed position. The plunger and the structure are positioned to generate a current when the housing is opened. The programmed value in the register is changed by the generated current and the processor takes an action responsive to the change in the programmed value.
