Abstract: The present disclosure provides a direct current (DC) transformer error detection apparatus for a pulsating harmonic signal, including a DC and pulsating harmonic current output module and an external detected input module, where the DC and pulsating harmonic current output module outputs a DC and a DC superimposed pulsating harmonic current to an internal sampling circuit and a self-calibrated standard resistor array; and the internal sampling circuit converts the input DC and the input DC superimposed pulsating harmonic current into a voltage signal, and sends the voltage signal to an analog-to-digital (AD) sampling and measurement component through a front-end conditioning circuit and a detected input channel. The DC transformer error detection apparatus can complete self-calibration for measurement of the DC and the pulsating harmonic signal on a test site.

Abstract: A composite package (100) comprises a plurality of primary packages (102) which are gathered into at least one secondary package (106) that comprises an envelope (104) about at least some of said primary packages (102), and a handle (108), and is characterized in that the handle (108) is mobile between a retracted first position substantially enclosed within said composite package (100), and an extracted second position projecting at least partially from said composite package (100).

Abstract: A disclosed apparatus includes a sensor housing. First and second magnets may be disposed in the sensor housing. A magnetic field sensor may be disposed between the first and second magnets. A sensor element may be positioned in a vicinity of the sensor housing, the sensor element to cause a magnetic field between the first and second magnets to substantially bypass the magnetic field sensor. The sensor housing may be coupled to a movable rail. The sensor element may be coupled to a fixed rail. The movable rail may be engaged with the fixed rail and movable relative to the fixed rail.

Abstract: A unipolar resistive ladder fluid-level sensor is provided. The sensor may include a tube immersed in a fluid, the tube containing a plurality of unipolar switches, and a float concentrically surrounding the tube. The float is configured to float in the fluid and to move relative to the tube in an axial direction as a height of the fluid level changes. The fluid-level sensor may further include a permanent magnet coupled to the float, wherein the plurality of unipolar switches are responsive to a magnetic field produced by the permanent magnet, and wherein the permanent magnet is one of: radially magnetized, and axially magnetized. In some approaches, the unipolar sensor is either a south-pole or north-pole activated sensor. In some approaches, at least one of the unipolar switches changes position in response to a negative magnetic field in an activation range of less than 1.0 millimeter.

Abstract: Provided are approaches for incorporating a plurality of sensors within a housing assembly coupled to a gear assembly. In one approach, a sensor apparatus includes a housing assembly including a first section and a second section coupled to the first section, and a set of speed sensors disposed within the first section. In one approach, the set of speed sensors is configured to detect rotational speed of one or more gears of the gear assembly. The sensor apparatus further includes a position sensor disposed within the second section. In one approach, the position sensor is configured to detect a position of a park lock element. The sensor apparatus further includes a printed circuit board (PCB) disposed within the housing assembly, wherein the set of speed sensors and the position sensors are connected to the PCB.
