  • Publication number: 20220105586
    Abstract: The invention relates to a wire-feed device for conveying a wire and to a method for feeding wire using a wire-feed device, in particular for a thermal joining apparatus, having at least one a drive element which can be operated by a feed drive and can be placed against a wire guided through the wire-feed device, exerting a contact pressure, in order to transfer drive movement by friction. According to the invention, an actuator which is coupled to the at least one drive element and can be controlled by a controller using the values measured for the contact pressure, is provided for variably setting the contact pressure acting on the wire.

  • Patent number: 10442255
    Abstract: A method for assigning identifiers of wheel electronics to the positions of the wheels on the vehicle is disclosed. The wheel electronics send their individual identifier with information relating to the rotational direction of the wheel and to the occurrence of an impact on the wheel to a receiver. An evaluation unit: collects the identifiers and rotational direction information and the driving speed, and on this basis, differentiates between identifiers of wheel electronics on the left and right vehicle side; differentiates impacts reported from wheel electronics on the left vehicle side, from impacts reported from wheel electronics on the right vehicle side; measures the time between impact signals reported from wheel electronics on the left or on the right vehicle side; multiplies the measured time by the driving speed measuring during this time; and checks whether the length formed by the multiplication coincides with an axle distance.

  • Patent number: 9908374
    Abstract: A tire module for attachment to an inside of a pneumatic tire for vehicles includes a device for measuring and/or monitoring the air pressure in the tire. A transmitter for transmitting radio signals, which contains information regarding the air pressure in the tire, includes a mechanical-electrical transducer having a flexible piezo-electrical element, which converts alternating changes in shape of the piezo-electric element caused by the rolling tire into electric energy and includes a storage unit for the electric energy, which is connected to the transducer. The transducer may contain a circular, disc-like, piezo-electric element, which in the following is described as piezo disc and on which an electrical voltage generated through the piezo effect is tapped off on contact points which are located on opposite sides of the piezo disc.

  • Patent number: 9296265
    Abstract: A tire pressure monitoring device is equipped for attaching to a wheel of a vehicle provided with pneumatic tires. The device measures the tire air pressure present in the pneumatic tire or a change of the tire pressure. An electrical circuit controls the tire pressure monitoring device. A memory stores a program for the electrical circuit. A first transmitter operates in a first frequency range for transmitting data out of the tire pressure monitoring device to a first receiver located outside the tire pressure monitoring device. In the memory initially a basic version of the program is stored, out of which multiple different versions of the program for multiple vehicle types can be developed. Subsequently, a fitting full version for a selected vehicle type is created in that program parameters intended for the selected vehicle type are subsequently stored in the memory of the tire pressure monitoring device.

  • Patent number: 8791807
    Abstract: Allocates identifiers of units of a tire pressure monitoring system to the positions of ABS-sensors which are each assigned to the wheels of the vehicle. The identifiers are contained in signals that are emitted by the units. Each unit, which is called a wheel electronic, has a pressure sensor, which is sensitive to the tire pressure of the wheel, a motion sensor, which provides information on the rotation speed of the wheel, a memory with the individual identifier of the wheel stored therein, and a transmitter, which transmits signals only containing information on the rotation speed of the respective wheel, to a receiver. An evaluation device receives the transmitted identifier and compares the information on the rotation speed of the wheel transmitted along with the identifier, with rotation speed information, which were acquired by the ABS sensors for the same time span and transferred to the evaluation device.

  • Patent number: 8198993
    Abstract: Described is a procedure for controlling the transmission operation of a tire pressure monitoring device (1) arranged in a pneumatic tire of a vehicle, whereby data telegrams are transmitted in a normal mode of operation (13) in first time intervals, and there is a changeover from the normal mode of operation (13) to a pressure drop mode, if an inspection of the pressure signals indicates a drop in the pressure of a drop speed exceeding a pre-defined threshold value, and data telegrams are transmitted in the pressure drop mode in second time intervals, which are shorter than the first time intervals, and the tire pressure monitoring devices (1) are put into a travel starting mode (10, 11, 12) at the beginning of the travel by activation a roll sensor. Data telegrams are transmitted in the travel starting mode in shorter third time intervals as compared to the normal mode of operation.
