The invention relates to a device and method for detecting the occupation of a seat in a motor vehicle. Said device comprises first sensor elements (SE1), which are flatly arranged on the seat surface of a vehicle seat and are part of a first sensor seat mat (OCSM) for measuring the weight or a weight profile on the vehicle seat. The device also comprises an evaluating unit (A), which is connected down from the sensor elements and provided for evaluating the first sensor signals of the first sensor seat mat (OCSM). The inventive device comprises additional safety sensor elements (SE2), which are flatly arranged on the seat surface of the vehicle seat, likewise connected to the evaluating unit (A), and provided for testing the operability of the first sensor elements (SE1). The inventive device is used in a method for detecting the occupation of a seat in a motor vehicle during which a control unit (S) of an occupant protection system adapts the triggering behavior of an occupant protection means to the determined occupation of the seat when the safety sensor elements (SE2) confirm the weight and/or the weight distribution established by the sensor seat mat (OCSM).

The invention relates to a portable handheld blower/vacuum apparatus having a housing and a blower scroll formed in the housing. An impeller is provided in the blower scroll. Air is supplied to the blower scroll via an air inlet and air is directed away from the blower scroll via an air outlet. An air-conducting connecting tube is mounted on the air outlet via a housing-fixed connecting stub. A bayonet connection is provided in the overlap region between the connecting tube and the connecting stub. The bayonet connection includes a guide path lying in the overlap region. The guide path includes an axial segment and a peripheral segment connected thereto in which a radial cam of the other part engages. The cam is secured form tight by a latch connection in the peripheral segment of the guide path to ensure a reliable, mechanically loadable attachment of the connecting tube in the connecting stub.

摘要:
The invention is directed to a positive-engaging coupling between a drive part and a driven part. The positive-engaging coupling includes an insert portion defining a first noncircular cross section and formed on the driven part. The drive part defines a receptacle for accommodating the insert portion therein and the receptacle has a second noncircular cross section corresponding to the first noncircular cross section. The insert portion and the receptacle conjointly define an intermediate space when the insert portion is inserted into the receptacle. An elastic insert is inserted into the receptacle for filling out the intermediate space when the insert portion of the driven part is disposed in the receptacle. If an overload occurs, the elastic insert is destroyed and the insert portion rotates freely within the receptacle.

A spray-forming output device for fluidic oscillators to provide relatively wide-angle three-dimensional output spray patterns is connected to the output of a fluidic oscillator. The device comprises mutually counter-directed conduits whose entry regions are fed from the oscillator output and whose exit regions are connected to an interaction outlet region that includes a common outlet, the common outlet being directed substantially orthogonally with respect to the plane in which the counter-directed conduits are disposed. In one embodiment, the interaction outlet region includes an impact wall disposed at the exit regions of the counter-directed conduits proximally to the common outlet. The spray-forming output device further comprises in one embodiment a shunt inertance conduit that provides an inertance shunt path between the entry regions of the counter-directed conduits, the shunt conduit being operative in smoothing out waveforms of the alternating flows from the oscillator and also providing for load-impedance matching between the oscillator and the output device. In operation, alternating output flows from the fluidic oscillator feed the counter-directed conduits and therefrom are deflected into the common outlet of the interaction outlet region. The alternating output flows mutually interact in the interaction outlet region and issue therefrom in the form of a substantially common fluid stream that oscillates or sweeps from side to side in correspondence with the oscillation of the fluidic oscillator.

A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction. After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet. The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet. A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vortex which is thereby alternately spun in opposite directions. An outlet opening from the output chamber issues fluid in a sweeping spray pattern determined by the vectorial sum of a first vector, tangential to the output vortex and a function of the spin velocity, and a second vector, directed radially from the vortex and determined by the static pressure in the chamber. By increasing or decreasing the static pressure, or by increasing or decreasing the vortex spin velocity, the angle subtended by the sweeping spray can be controlled over an unusually large range. By properly configuring the oscillator and/or output chamber, concentrations and distribution of fluid in the spray pattern can be readily controlled.

To verify that the handset of a cordless telephone unit is still within the radio coverage area of the fixed station, rather than attempt to establish connection with the switched network and verify contact as a result of receiving a dial tone, or dialing a special number in the network, a user can merely activate a radio coverage verification circuit in the handset and fixed station. Through use of these circuits, in addition to the identification number of the station, a code is transmitted. The identification and code, when received by the opposite station, are verified with number and code values stored in that station, and the number and code are then retransmitted as an acknowledgement signal. An annunciator in the handset provides a visual or aural warning to the user if the acknowledgement signal is not received, indicating that the handset is not within the radio coverage area of the fixed station.
摘要:
A small, but nevertheless high-flow fluidic oscillator has a dual level body portion including an interaction chamber in a first level. An inlet plenum supplies fluid to a supply nozzle which enters directly into the inlet end of the interaction chamber to direct a jet flow from the supply nozzle, through the interaction chamber and out of an outlet opening. A fluid passage is located at least partly in the second level of the body portion, and connecting passages on either side of the supply nozzle connect the fluid passage to the inlet end of the interaction chamber. The walls of the interaction chamber converge from the inlet end toward a neck portion and thereafter diverge and then converge again at the outlet so that a fluid column extends between the jet flow and the sidewalls of the interaction chamber, and moves cyclically back and forth through the fluid passage and the connecting passages to obtain interaction between the fluid column and the jet flow without the need for control nozzles.
