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.

摘要： A motion control device for controlling a motor is presented. The motion control device is operable to scale or adjust an input relative to an input range that is based on calibration values and to use that scaled input to produce a drive signal to drive the motor. The motion control device performs a self-calibration to produce the calibration values. The self-calibration involves measuring home position and full travel position values for the motor.

摘要： A time indicator that provides a color indicia after a predetermined period of time has passed after activation. The time indicator includes a substrate, e.g., a clear or transparent 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 of a smaller 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 and a second reactant is adhered to the upper surface of the second portion of the substrate. When the first portion is 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. This exposed area may be used to attach the indicator to an article or documents. When so folded the first reactant and second reactant contact each other to activate the indicator and to provide the color indicia after the predetermined period of time after activation passes. In one embodiment, the indicator is used to detect the presence of a chemical residue, e.g., explosive compound residues.

摘要： A self-expiring badge or label is provided that includes a clear substrate, an opaque adhesive layer, a liner web, and an ink pattern is provided. The clear substrate has a back surface and a front surface with the opaque adhesive layer on the back surface. The liner web has a first surface and a second surface, where the adhesive layer secures the substrate to the first surface. The ink pattern is on at least a portion of the second surface. Upon removal of the liner web from the adhesive layer, the portion remains secured to the clear substrate by the adhesive layer and the clear substrate is foldable to place the ink pattern in contact with the adhesive layer. The ink pattern migrates through the adhesive layer in a selected time interval and is visible through the clear substrate when the ink pattern is in contact with the adhesive layer.

摘要： A process for validating an identification badge or plastic card for a plurality of predetermined periods of time. The process includes generating, preferably randomly, an initial image for an initial predetermined period of time and then transmitting this initial image to a printing device. The printing device prints the image on the identification badge to thereby validate the badge for the initial predetermined period of time. Thereafter, a subsequent image is randomly generated for a subsequent predetermined period of time. This subsequent image is then transmitted to the printing device. The initial image is then removed from the identification badge and the subsequent image printed on the identification badge to validate the badge for the subsequent predetermined period of time.
