The hydraulic regulating device for an automatic transmission system in motor vehicles having a plurality of hydraulic couplings, includes a single pressure build-up regulating valve and a single pressure decrease regulating valve and assigned to each coupling a solenoid operated directional control valve having its working port connected to the couplings, its pressure port connected via a switch-on reversing valve to the pressure build-up regulating valve, and its return port connected via a switch-off reversing valve to a return conduit; both reversing valves are controlled according to predetermined pressure levels on the coupling so that in the working position of the switch-on reversing valve the coupling is connected to a stable high pressure and when the coupling process is initiated by reversing the position of the directional control valve, the switch-off reversing valve connects the coupling element to the pressure decrease regulating valve.

In first gear, a brake band prevents one gear of the planetary gearing of an automatic transmission from rotating. In second gear, a clutch causes this gear to rotate as a unit with the drive and driven shaft of the transmission. For an upshift under load, the clutch is engaged slowly, thereby decreasing the required brake torque. The brake force is therefore decreased at a corresponding rate. A switch having a movable contact is mounted so that the contact is moved in response to the reactive force created between the brake band and the gear box. This reactive force varies as a function of the brake force and also depends upon the direction of movement of the braked member. The switch is set to a threshold value which is substantially less than the brake force applied in first gear. At the freewheel point, that is the point at which the moment of the brake member changes direction, the brake force has been decreased sufficiently that the change in direction of the moment will cause the switch to pass the threshold value thereby generating a signal. This signal is processed to cause full disengagement of the brake. The switch will also pass the threshold value when, after complete disengagement of the brake, a change in direction of moment of the member occurs. At this point the brake is fully engaged in a downshift under load.

Systems for providing and tracking information, including location and credentials, of a person and providing this information to a user on a display. The system provides multiple views on the display including a room view to indicate who is in a specified room or other location, a team view to indicate a person's position in an overall service team, and a timeline view to indicate the times and durations of service events involving one or more persons.

A hearing aid device and a method of manufacturing the hearing aid device provide a housing and a first conductive layer. The housing has a first non-conductive layer and a second non-conductive layer. The first conductive layer is disposed between the first non-conductive layer and the second non-conductive layer.

A hearing device has an ear fitting piece, a housing part wearable behind the ear, and an earpiece tube connecting the ear fitting piece and the housing part. The transmission of mechanical vibrations between the ear fitting piece and the housing part via the earpiece tube is prevented by damping elements located in the region of the connection points between the ear fitting piece and the earpiece tube, or between the earpiece tube and the housing part. The damping elements damp mechanical vibrations in the transition region. A damping element that prevents the transmission of mechanical vibrations can also be present on or in the earpiece tube. The feedback tendency in the appertaining hearing device is thereby reduced.

The penetration of moisture and dirt often leads to a premature failure of electroacoustic miniature transducers that are used in hearing aids. A transducer membrane of a miniature transducer is provided at least in part with a hydrophobic and/or oliophobic and/or biofilm-inhibiting coating that, because its layer thickness is less than 10 μm, does not significantly influence the acoustic characteristic of the miniature transducer, and that prevents degradation of the transmission characteristic due to moisture, or moisture-caused damage to the miniature transducer. In addition, the adherence of dirt particles is prevented.

An energy storage means holding device and an associated housing module for a hearing device are provided. The holding device includes a holding module and a contact arranged in the holding module for connection to an energy charging device. A gripping is embodied in the holding module and cover the contact such that the contact can be contacted outside but cannot however be reached by human fingers when inserting the holding device into a housing module of the hearing device.

The invention specifies a sealing apparatus for a microphone opening in a front plate. It comprises a sound-permeable covering medium made of a first material and a sound-permeable membrane, with a sealant arranged on the exterior of the covering medium made of a second material being designed so as to produce a tight form fit between the covering medium and the front plate when said covering medium is inserted into the microphone opening. A front plate that is compatible with the sealing apparatus according to the invention is also specified. The advantage here is that the microphone opening can be sealed in a water-tight fashion and as a result protects a microphone positioned beneath it against external influences.
摘要:
A sound transmission apparatus that includes an outer component and an inner component, with the outer component surrounding the inner component at least partially and with at least the inner component having a through opening is provided. The sound transmission apparatus also includes a film-type component, which seals the through opening of the inner component on one side. The outer and the inner component here are connected to one another as a single piece in one working step via a multi-component injection molding method.
