Abstract: The invention relates to a method for data transmission (28) in the case of a resistance welding current source (1) and to a resistance welding current source (1), wherein during a welding operation (25) welding pulses (20) are generated in an inverter (8) with inverter switching elements (S1, S2, S3, S4) cyclically with a switching frequency (34) and a pulse duration (33) and are applied to the primary side (9) of a transformer (2) and are rectified on the secondary side (11) of the transformer (2) by a rectifier (12) with rectifier switching elements (S5, S6) to form a resultant welding current (IS). In order to be able to dispense with data lines between the power unit (5) and the transformer (2), in a data transmission mode (24) the impedance (23) at the primary side (9) of the transformer (2) is increased in the breaks in the welding operation (25), control pulses (29) for initializing the data transmission mode (24) are applied by a control device (26) to the primary side (9) of the transformer (2), which control pulses (29) are detected on the secondary side (11) of the transformer (2), whereupon the rectifier switching elements (S5, S6) of the secondary-side rectifier (12) are actuated in a way corresponding to the data to be transmitted, and so the current (ITR) on the primary side (9) of the transformer (2) is modulated with these data, and the data are thereby transmitted via the transformer (2).

Abstract: A system and method of coordinating power states between two detachable units is disclosed. Only the primary unit has a user-controllable power control. The secondary unit is not directly user controllable. The power states of the two units are coordinated using an actuator mechanism when the units are attached. When the two units are detached, the state of the secondary unit is dependent upon the state of the primary unit and any subsequent commands transmitted by the primary unit to the secondary unit.

Abstract: An electro-pneumatic transducer for controlling gas pressure is disclosed. The transducer includes a nozzle body and a valve housing interconnected therebetween by a nozzle and a solenoid assembly including a magnetized valve assembly and a solenoid having a top portion and a bottom portion, which when energized generate a magnetic field having a predetermined polarity in response to which the magnetized valve assembly is actuated to control gas flow through the nozzle. The transducer also includes a control circuit adapted to receive an input signal. The control circuit is configured to energize the solenoid in response to the input signal to generate the magnetic field thereabout to actuate the valve assembly. The transducer further includes a capacitor coupled to the control circuit, wherein upon loss of the input signal, the control circuit signals the capacitor to provide an electrical signal to the solenoid to actuate the valve assembly.

Abstract: Wireless, battery-less, asset sensor and communication system (10) comprising battery-less sensor (40) integrally housed within a first housing and reader device (20) integrally housed within a second housing. Reader (20) is coupled to handheld portable data collector (PDA) (60) and wirelessly transmits a time varying signal S 1 . When this signal is directed at battery-less sensor (40), battery-less sensor (40) derives power from the wirelessly transmitted signal, powers up, then measures/senses and converts analog signals (102) from an asset such as machine M to digital asset data (104). Digital asset data and optionally stored asset information is formatted to modulate the transmitted signal (S 1 ) for transmitting asset data and information back to the reader (20) wherein the modulated transmitted signal (S 2 ) is demodulated and communicated to the PDC (60).
