The present invention relates generally to acquisition of data from RFID devices (132-136), such as sensor data. Prior art systems of active RFID devices have a problem of high average power consumption, and therefore, the energy source of the RFID devices needs to be replaced or charged frequently. The present invention provides a new solution wherein the RFID device has a power saving mode in which the receiver of the RFID device has a decreased ability to receive/detect RF signals. The RFID device may include a timer which is functional during the power saving mode, and the receiver of the RFID device will turn into active mode at a point of time based on the time value of the timer. Signal strength of an RF channel is indicated with a receiver, and transmission of data is dependent on the indication of the signal strength.

Between the holders in the housing and the electrical or electronic modules, a vibration decoupling element is disposed.

An electrical connector arrangement includes a resilient contact adapted for direct engagement with the bare wire of an insulated conductor without the use of any assembly tool, characterized in that the resilient contact includes a first leg having a first end containing a window opening, a second leg having a first end extending at an acute angle through the window opening for clamping engagement with a conductor bare wire that is also inserted in the same direction therein, and a connecting portion connecting the other ends of the first and second legs to define a closed loop. A clamping edge at the extremity of the first end of the second resilient contact leg engages the bare wire and cooperates with a first edge of the window opening to prevent the withdrawal of the bare wire from the window opening. A conductive bus bar may be provided that includes a projecting portion that extends into the window opening between the bare wire and the window first edge, whereby the bare wire is clamped between the clamping edge of the second leg of the resilient contact and the bus bar projecting portion.

An external resistor is connected to a detection terminal. A pulse modulator is configured to generate a pulse signal S_PWM having a duty ratio adjusted such that the output voltage V_OUT of a DC/DC converter approaches a target value. A pulse modulator is configured to switch the pulse signal S_PWM to a level that corresponds to the off level of the switching transistor according to a detection voltage V_S that develops at the detection terminal. A short-circuit detection circuit is configured to generate a short-circuit detection signal which is asserted when the detection voltage V_S is higher than a predetermined threshold voltage V_TH after a judgment time elapses after the pulse signal S_PWM is switched to an on level that corresponds to the on state of the switching transistor. When the short-circuit detection signal is asserted, the pulse modulator is configured to switch the pulse signal S_PWM to the off level.

This invention relates to medicine, in particular to surgical devices for curing the locomotor apparatus with the aid of osteosynthesis. In order to improve operational reliability during implantation, the structure of the inventive device for elongating long bones is embodied in such a way that the axes of the bearing part and the thread screwed part of a screw-holder are offset at a distance ranging from 0.5 to 0.8 mm. A boss (bulge) is embodied on the external body of the device on the side of the orifice in which said screw-holder is fixed. The specific structural embodiment of a finger makes it possible to reduce the traumatic effects of a surgical operation.

This power and safety control hub for overall power control, safety control and power distribution integrates fault tolerant power disconnect control, software monitoring of disconnect and multi-voltage power distribution and disconnect with non-hazardous power control, EMI filtering and multi-circuit current protection in a single unit. In addition, it implements electromagnetic, single fault tolerant, safety control circuits without using positively driven contact relays. It coordinates the shutdown of any connected mechanical drives such as servo motor drives, stepper motor drives and variable speed drives autonomously commanding them to come to a controlled stop before safety power is disconnected (when networked controls are used). It also integrates segmented hazardous power control (load/unload and main machine/equipment areas) so that the main area can be operating while the load/unload area has power disconnected. Further, it automatically discharges energy sources within connected mechanical drives at the time of safety power disconnect of hazardous power. It also utilizes a safety control and monitoring algorithm that automatically forces the test on e-stop switches and interlocks in a machine each time the machine is powered up or reset. In addition, it has a state driven safety control and monitoring algorithm that pinpoints wiring and device problems for rapid debug. It includes internal self-protection that automatically forces a control safety power disconnect (after warning the host) if the unit should approach its maximum operating temperature, or if a cooling fan stops. Further, it incorporates safety monitoring software for the synchronous de-bouncing of the interlock and e-stop switch inputs (as a vector) to eliminate false trips. It also integrates a comprehensive audible overcurrent trip indicator as well as individual visual overcurrent indicators in the power distribution system and an e-stop reset function into the machine on-off front panel switch. Finally, our power and safety control hub for overall power control, safety control and power distribution includes a “soft-off” circuit that automatically shuts off the machine when the power supply voltage to a host computer is shut down.
