Abstract: A four-wheel drive hub lock harness assembly is disclosed. The harness assembly comprises a motor receptacle configured to retain a motor. The motor receptacle comprises a retainer and lead frame assembly configured to house a printed circuit board, a magnetic sensor electrically coupled to the retainer and lead frame assembly, a first and second bracket extending substantially vertically from the retainer and lead frame assembly, the first and second brackets configured to secure corresponding ends of the motor to the retainer and lead frame assembly, and encapsulation material encapsulating the printed circuit board and magnetic sensor for dampening vibrations of the wheels of a vehicle. The harness assembly also comprises a housing assembly situated beneath the motor receptacle, which mechanically connects with the eIWE, and a cable extending from the housing assembly, the cable configured to electrically connect the hub lock harness assembly to a powertrain control module (PCM).

Abstract: A piezoelectric sensor and amplifier for use with an auditory aid device are disclosed. The piezoelectric sensor includes a top sensor and a bottom sensor disposed on opposite surfaces of a flex printed circuit board. The top and bottom sensors are made of a piezoelectric material, such as PVDF. Further, the piezoelectric sensor is adapted to be implanted into a subject's ear, where the piezoelectric sensor is cantilevered with the free, or distal end, touching the umbo. The proximal end is held in place by a support that is affixed to the ear. Additionally, the piezoelectric sensor is shaped so that the width of the distal end is less than the width at the proximal end. Further, the piezoelectric sensor generates differential signals, which are then amplified using a differential amplifier circuit.

Abstract: A substrate having an undulating surface forming a series of rounded peaks and valleys that produce a continuously curving surface across at least a portion of the substrate. The undulating surface defines a first set of micro features. A second set of micro features molded on the first set of micro features. The substrate is a compression molded polymeric material in which the first and second sets of micro features are formed on the substrate during a single molding step, and wherein the first and second sets of micro features cooperate to increase the surface area and affect at least one of adhesion, friction, hydrophilicity and hydrophobicity of the substrate.

Abstract: A process and a plant for obtaining highly pure methane from biogas where biogas coming from a fermenter is compressed and fed to at least one membrane unit having a selectively permeable membrane, which provides a product gas stream containing an elevated proportion of methane and a gas stream containing a reduced proportion of methane. A quality sensor may be arranged in the outlet line for the highly pure product gas. A vacuum pump, the capacity of which can be regulated, may be connected to the low-pressure side of one of the membrane units. It is controlled by a control unit which receives its input signal from the quality sensor in the outlet line, and if the proportion of methane measured by the quality sensor falls below a certain value, the capacity of the vacuum pump is regulated so that the pressure difference at the membrane increases.
