Abstract: Methods, apparatus, and systems are provided for collecting data from a plurality of downhole sensors located in a wellbore utilizing an asynchronous direct-sequence code division multiple access (DS-CDMA)-based communication scheme. One example method includes receiving a superposed signal comprising asynchronous signals from the downhole sensors, wherein a spreading sequence has been applied to data generated by each of the downhole sensors to form each of the asynchronous signals; sampling the received superposed signal; and processing the sampled superposed signal using decorrelation to determine the data from at least one of the downhole sensors before the spreading sequence was applied.

A stopping mechanism is provided with at least two axially offset stopping element sections, which can be adjusted either individually or jointly to the at least one torsion sleeve and to the torsion rod through the use of a control mechanism depending on the energy absorption capacity to be applied.

Abstract: A safety belt reeling device with comfort function has a housing and a reeling shaft rotatably supported in the housing. A pawl wheel is fastened to the reeling shaft and switchable between a locked position in which rotation of the pawl wheel is blocked and a release position in which the pawl wheel is rotatable. A winding spring, connected with a first end to the housing and with a second end to the pawl wheel, is provided for rotating the reeling shaft when the pawl wheel is in the release position. A comfort spring with a weaker spring force than the winding spring is provided. The comfort spring is connected with a first end to the pawl wheel and with a second end to the reeling shaft. The pawl wheel has a stay with a first and a second end. The first end of the comfort spring is guided in a single loop about the first end of the stay. An elastically deformable dampening element is positioned between the first end of the stay and the single loop.

Abstract: From a holding fixture for a safety belt fastening arrangement there emanates, on two opposite sides, in each case one elongated connecting part, by virtue of whose free end a locking part of a safety belt is secured. These two connecting parts are formed exclusively from a safety belt strap and are held together, on the holding fixture side, by at least one stitch seam.

Abstract: A motor vehicle is disclosed having a safety belt assigned to a seat and having an airbag system which is assigned to the same seat and has a pressure gas source which can be actuated by means of a deceleration sensor. In order to optimize protection for the seat user in the event of an accident, the invention proposes that at least two pressure gas sources which can be actuated independently of one another are provided, and in that in the event of an accident only one pressure gas source can be actuated by means of the deceleration sensor when the safety belt is being worn, while when the safety belt is not being worn all the pressure gas sources can be actuated so that it is only in this case that the maximum airbag internal pressure is available.

Abstract: In a vertically displaceable safety belt fitting, to ensure that, even when high displacement forces occur, a first catch element of the slideably displaceable anchoring element received by a guide rail fixed to the vehicle body executes a downwardly directed movement after it has run up against an associated pawl and after an actuating button has been released, whereby, when the button is depressed again, the first catch element becomes capable of moving the associated pawl away, it is proposed to equip a release element carrying the first catch element with an upwardly directed slot on the same side as the bearing and to provide the release element with a spring which engages on the top side of the release element.

Abstract: The application relates to an anchoring of end points of safety belts or safety belt buckle attachments for rear seats of motor vehicles with rear-wheel drive, especially passenger vehicles or estate cars, in the vehicle floor region. In order to stiffen such an anchoring so that the mounting points cannot travel in the direction of the tensile forces occuring in the case of stressing as a result of an accident, the invention provides for the end points, together with a bridge passing under a drive shaft, to be fixed to the vehicle floor on both sides of the drive shaft.

Abstract: A device for automatically adjusting the height of the deflection fitting of a safety belt in vehicles having an anchoring element which carries the deflection fitting and is vertically displaceable in a guide rail firmly attached to the vehicle which includes an adjusting mechanism for displacing and holding the anchoring element in the vertical position set and has a locking device which is effective in the case of extreme vehicle deceleration to be connected to a vehicle deceleration sensor for locking the anchoring element in the guide rail by transverse displacement of a locking element, coupled to the anchoring element, due to the downward movement of the anchoring element caused by the deflection fitting.

Abstract: The invention relates to a lock for safety belts, which is designed to receive a lock tongue provided with a deflection web and is equipped with a press button and which is arranged next to a high storage compartment, center armrest or the like. To make it possible to actuate the lock easily and properly for safety purposes in spite of the high storage compartment located next to it, according to the invention, the top edge of the lock tongue and/or of the press button extends upwards relative to the load bearing deflection web of the lock tongue into the vicinity of the top edge of the storage compartment, center armrest or the like.

Abstract: A passive restraining system for an automobile provides a means, in the event of an automobile accident, for inflating an air bag system on the driver's side at a lower threshold speed if the driver is not wearing a seat belt, and at a higher threshold speed if the driver is wearing a seat belt. This system, however, allows a second air bag system to inflate for protecting the front seat passenger in the event of an accident, at the lower threshold speed, regardless of whether the passenger is wearing a seat belt or not.

Abstract: A guide device for a safety belt of a safety belt system for a motor vehicle.

Abstract: Optical glass is disclosed which has an increased resistance to solarization and irradiation as well as little or no undesirable coloring. This glass is designed to exhibit as many properties having optimal values as possible. The silicate glass used is free of alkaline earth metal oxides and incorporates CeO.sub.2 and both zinc and strontium ions in very small concentrations. The latter two materials further improve the solarization and irradiation resistance properties of the glass. Furthermore, as the zinc and strontium ions are effective when used in low concentrations, they serve to minimize any undesirable glass coloring.

The drag disk includes an engagement arrangement on a bearing surface thereof which cooperates with the gear in a belt take-up direction and is subject to the action of an additional spring in the belt extraction direction. A stop is provided on the reel housing for delimiting the rotational movement of the drag disk with the stop cooperating with two matching stops on the spring-loaded drag disk. The reel housing includes a curved control and guide track or surface which cooperates with a guide pin on the drag disk.
