摘要： A long term rapid color changing time indicator includes a front part and a back part. The front part includes a transparent layer, an opaque layer, a colorant layer, and a neutralizing layer. The colorant layer includes a matrix and a colorant having a non-migratory form that does not migrate in the matrix and having a migratory form that migrates in the matrix. The back part has a reactant. When the front part and the back part are placed in contact, the reactant migrates into the neutralizing layer and a portion of the reactant is depleted by a coreactant. The unreacted reactant migrates into the colorant layer and reacts with the non-migratory form of the colorant converting the non-migratory form to the migratory form such that the migratory form of the colorant migrates through the opaque layer to cause a visual color indication in the transparent layer.

摘要： A time indicator assembly including a front part and a back part is disclosed that can easily pass through a printer. The time indicator assembly includes a base substrate forming at least part of the back part having a first surface and a second surface extending between edges. A migrating ink is applied over a portion of the first surface of the base substrate, and a release sheet overlies the migrating ink to prevent migration of the migrating ink toward the front part. In one embodiment, an adhesive is applied over the release sheet and onto the base substrate adjacent at least two of the base substrate edges. The adhesive joins a cover substrate forming at least part of the front part to the base substrate over at least a portion of the release sheet and along the at least two of the base substrate edges. Upon removal of the release sheet, the migrating ink migrates through the adhesive to form an image in the cover substrate. In another embodiment a lift strip is formed in at least one of the front part and back part for easily separating the front part and back part to expose and remove the release sheet.

摘要： Presented is a sensor that includes a magnetoresistive (MR) sensing device to sense a magnetic field and to produce an AC signal voltage proportional to the sensed magnetic field. The sensor also includes circuitry, coupled to the MR sensing device, to remove DC offset from the AC signal voltage. The DC offset may be related to the hysteresis characteristics of the MR sensing device. To remove DC offset, the circuitry may obtain an averaged DC offset and subtract the averaged DC offset from the AC signal voltage to produce a sensor output signal.

摘要： According to typical inventive practice, a cylindrical or prolate spheroidal marine hull has two congruent contra-rotative propellers coaxially situated at or near its axial ends. Each propeller has plural blades mechanically and/or flexibly attributed with changeability of blade pitch angles and blade flap angles. A blade-pitch control system adjusts the individual blade pitch angles of both propellers. The blade-pitch control system may be electronically and/or mechanically actuated, and is capable of: (i) cyclically adjusting the blade pitch angles of the two propellers so as to select two respective blade-tip-path planes, each characterized by a direction of thrust that is associated with the blade flap angles and is generally perpendicular to the blade-tip-path plane; (ii) collectively adjusting the blade pitch angles of the two propellers so as to select two respective magnitudes of thrust. The cyclic and collective blade commands, algorithmically coordinated, determine the direction, orientation, and speed of the hull.

摘要： A mechanism for assigning unique addresses to identical devices attached to a serial bus is presented. Each device has at least one output and is provided with a storage device to provide a configurable portion of a bus address having a fixed portion and a configurable portion. The device is further provided with circuitry, coupled to the storage device and the output, to determine a state of the output and use the state to configure the configurable portion. Once the configurable portion is configured, the bus address uniquely identifies the device. Such configuration allows more than one such device to be coupled to the same serial bus, e.g., an I2C bus.

摘要： An indicator is disclosed that detects the presence of a chemical residue. The indicator includes a substrate having an upper surface and a lower surface and a first portion and a second portion joined at a fold line. The first portion is smaller in area than the second portion. An adhesive coats the upper surface of at least the second portion of the substrate. A first reactant is adhered to the upper surface of the first portion of the substrate. When the second portion is contacted with a surface containing the chemical residue, the residue adheres to the adhesive and when the first portion is subsequently folded along the fold line so that the upper surfaces of the substrate contact each other, a portion of the adhesive on the second portion remains exposed and the first reactant and chemical residue react to provide the color indicia indicating the presence of the chemical residue.
