A casing for a fluid pump is provided. The casing includes a unitary, single-piece, elongated shell having opposite first and second open ends. A circumferential bead is formed in the shell. A sleeve is received in the first open end of the shell. The sleeve is disposed between the bead and the first open end. A heat sink cap is received in the first open end and engages the sleeve. The shell includes a crimp formed at the first open end. The crimp contacts the heat sink cap and retains the heat sink cap in the first open end. The shell includes a lip formed at the second open end. A motor section and at least a part of a pumping section of the pump are encapsulated within the shell between the lip and the crimp. A fluid pump and a method of encapsulating the fluid pump are also provided.

A fluid pump includes a fluid pump inlet and a fluid pump outlet. A motor includes an armature and a stator such that the armature rotates about an axis. A pump section includes a pump section having a pumping element coupled to the armature such that rotation of the armature rotates the pumping element such that the pumping element pumps fluid from the fluid inlet to a pump section outlet of the pump section. A fluid passage within the fluid pump provides fluid communication from the pump section outlet to the fluid pump outlet such that the armature in part defines the fluid passage. The armature includes blades arranged in a polar array centered about the axis such that each of the blades extends in a helix about the axis and such that the blades define chambers. The chambers are in constant fluid communication with the pump section outlet.

A fluid pump includes a fluid pump inlet and a fluid pump outlet. A motor includes an armature and a stator such that the armature rotates about an axis. A pump section includes a pump section having a pumping element coupled to the armature such that rotation of the armature rotates the pumping element such that the pumping element pumps fluid from the fluid inlet to a pump section outlet of the pump section. A fluid passage within the fluid pump provides fluid communication from the pump section outlet to the fluid pump outlet such that the fluid passage is radially between the armature and the stator. The armature includes a surface of which faces toward the pump section and includes a plurality of recesses extending thereinto.

A sensing apparatus for determining a property of a fuel such as a gasoline and ethanol blend known as flex fuel includes an acetal plastic tube with an inlet, an outlet and a fuel passage in between. One property of the fuel is a dielectric constant. A pair of sensing plates are placed on opposite sides of the tube leaving the fuel passage unobstructed. A processing circuit on a printed circuit board (PCB) is located near to and is connected with the sensing plates. The circuit applies an excitation signal, senses a capacitance, and generates an output signal indicative of a property of the fuel. The sensed capacitance will increase with increasing concentration of ethanol in the fuel flowing through the passage. A shield for reducing EMI surrounds and encloses the sensing plates and the PCB. An interface connector allows the sensing apparatus to output the capacitance indicative signal to an engine controller or the like.

A non-contacting, magnet-based, rotary and linear travel absolute position sensor each include a stationary galvanomagnetic sensing element disposed in an air gap or slot of a movable magnet/flux concentrator assembly. The assembly has a first flux concentrator comprising ferromagnetic material having opposing magnet ends, and a second flux concentrator also comprising ferromagnetic material having opposing magnet ends but that is spaced apart from the first flux concentrator by a pair of magnets to form the air gap or slot. The magnet ends of each flux concentrator have a respective magnet area configured to engage a corresponding magnet and is configured in size and shape to cover the magnet. Additionally, the flux concentrators are configured in geometry to decrease in cross-sectional area from the inboard side of the magnet ends towards the center region of the concentrators, specifically the center of travel together provide improved linearity and signal to noise ratio of the output position signal.

A sensor assembly with a universal sensor module for sensing angular position of a rotatable object is provided. The universal sensor module includes a module housing. The sensor module further includes a rotatable assembly in the module housing configured to define a bore for interchangeably receiving one of the following: the rotatable object, and an interface adaptor for receiving the rotatable object. A bearing device allows rotational movement between a stationary assembly and the rotatable assembly. The sensor assembly is configured to accommodate an array of diverse sensing applications with the universal sensor module.

An arc magnet assembly with a virtual radial magnetization is established by placing a series of small trapezoidal-shaped magnet segments having axial magnetizations side by side to form an arc. The arc magnet assembly may be affixed to a rotating component in, e.g., a vehicle to yield a substantially linear magnetic sensor output that represents the speed and/or direction of rotation and/or position of the rotating component.

A contactless latch engagement detector for a mechanical fastening system operating on the principle of magnetosensitivity. A magnetosensitive switch composed of a magnetosensitive device and at least one biasing magnet adjacent the magnetosensitive device are located in a buckle. Within or external to the buckle is an electronic circuit for driving the magnetosensitive device, and a flux bar composed of a ferromagnetic material having a high magnetic permeability is associated with a movable component of the system. In operation, the electronic circuit drives the magnetosensitive device, wherein its output is responsive to position of the flux bar relative to the magnetosensitive device. The flux bar moves responsive to position of a tongue within the buckle, whereby the fastened state of the mechanical (ie., seat belt) fastening system is detected when a predetermined output occurs.

A self-compensating control circuit for use with a magneto-resistive sensor. The control circuit includes a first stage amplification and offset function that removes a DC component from the input signal and maximizes an AC component of the input signal within the dynamic range of the control circuit. Subsequent stages remove the remaining DC component, if any, and provide suitable additional amplification. A comparator provides a digital output based on the processed input signal and a threshold signal.

A magnetostrictive sensor for outputting a signal representative of torque on a shaft includes one or more excitation coils that generate magnetic flux which permeates the shaft and pickup coils that detect the flux after the flux passes through the shaft. Torque on the shaft affects the magnetic flux passing through the shaft. A coupling member such as plural rollers or powder metal poles are disposed in the flux path and touch the shaft such that no air gap exists in the flux path. Consequently, the sensor is comparatively sensitive, and is not unduly effected by shaft run-out.
