| 20090189688 | HIGH DYNAMIC RANGE ASK DEMODULATOR FOR USE IN AN RFID TRANSPONDER - An ASK demodulator for use in an RFID transponder having a limiter circuit associated with the antenna circuit and converting the ASK antenna fieldstrength modulation into an ASK limiter current modulation by limiting the antenna voltage to a fixed value and thereby causing the limiter current to be substantially proportional to the ASK antenna field strength, and a current discriminator circuit that discriminates the ASK limiter current modulation. By converting the fieldstrength modulation into a proportional limiter current and discriminating that limiter current, a linear relationship and a stable demodulator sensitivity are achieved. The current discrimination can be made accurately under low-voltage conditions. | 07-30-2009 |

| 20090174592 | RFID TRANSPONDER WITH PLL - An RFID transponder comprises an antenna for receiving data in a downlink mode and transmitting data in an uplink mode, with a modulation stage for modulating uplink data and a demodulation stage for demodulating downlink data. A class C amplifier is provided, which has a resonant circuit, a plucking device coupled to the resonant circuit, and a controllable pulse width generator coupled to the plucking device. The controllable pulse width generator is adapted to periodically switch the plucking device on and off so as to maintain an oscillation of the resonant circuit. The transponder further comprises a phase locked loop configured to be locked to an oscillating signal received through the antenna and to be switched into a free running mode without being locked to the oscillating signal received through the antenna, thereby being adapted to output an independent internal clock signal for the RFID transponder. | 07-09-2009 |
| 20100141389 | RFID TRANSPONDER WITH IMPROVED WAKE PATTERN DETECTION AND METHOD - An RFID transponder is provided which includes an automatic gain control (AGC) stage for amplifying a radio frequency (RF) signal and for providing an amplified RF signal. The AGC stage has a control signal indicating an increase of the amplitude of the RF signal. A demodulator is coupled to receive the amplified RF signal for demodulating the amplified RF signal. The demodulator provides a data signal. A burst detector is coupled to receive the control signal of the AGC stage and adapted to provide a start signal in response to a change of the control signal. A wake pattern detector is coupled to receive the data signal and the start signal. The wake pattern detector is adapted to detect a predefined wake pattern in the data signal after having received the start signal and to issue a wake signal if the predefined wake pattern is detected for switching the RFID transponder from a first operating mode into a second operating mode having higher power consumption than the first operating mode. | 06-10-2010 |

| 20100132153 | CLEANABLE FILTER SYSTEM - A cleanable filter system includes a filter housing having an inlet for dust-laden gas and an outer annular gap volume disposed about an inner volume. The inner volume and the outer annular gap volume extend axisymmetrically about a bisecting line and are separated from one another by at least one gas-permeable wall. A submicron particulate filter is disposed in the inner volume. A discharge pipe is sealingly disposed in the inner volume axisymmetrically about the bisecting line. The discharge pipe includes a peripheral cylindrical surface that is gas-permeable and covered by the submicron particulate filter. A purge-gas conduit is disposed in the discharge pipe and configured to be rotationally driven about the bisecting line. The purge-gas conduit includes at least one radially outwardly directed nozzle disposed in a region of the submicron particulate filter. | 06-03-2010 |

| 20100122723 | Photovoltaic Power for Communications Networks - Methods, systems, and products are disclosed for providing photovoltaic power to a communications network. AC electrical power is measured that is consumed in a rectifier that produces a DC output to a telephony transmission line. The DC output is measured in the telephony transmission line. Photovoltaic power is measured that is produced by a photovoltaic device that is applied to the telephony transmission line. The consumption of the AC electrical power in the rectifier is reduced in response to the photovoltaic power produced by the photovoltaic device. | 05-20-2010 |

| 20110318715 | RECOIL IMPULSE GENERATOR FOR A WEAPON SIMULATOR - The invention relates to a recoil impulse generator for a weapon simulator comprising a force storage element and an impulse mass that can be moved and that is moved from a stressed to an unstressed position with a triggering element is actuated in order to simulate a recoil impulse. The recoil impulse generator comprises a drive that drives a spindle uniterruptedly during a shot sequence simulating several shots; a coupling that is connected to the impulse mass and to the force storage element and that engages in the spindle in an engaged state and that is moved along the spindle by means of rotation of the spindle in order to bring the impulse mass into the stressed position again the force applied by the force storage element; a disengaging means that switches the coupling to a disengaged state when the impulse mass has reached the stressed position; and an engaging means that switches the coupling to the engaged state when the impulse mass has reached the unstressed position. | 12-29-2011 |

| 20120039170 | Dynamic Load Control for Downlink Signaling Channels - A number of channel coding elements per transmission time interval required to transmit control information to a communication terminal is evaluated based on communication connection condition information with respect to the communication terminal, wherein the control information is defined by information on the scheduling of communication resources allocation to the communication terminal. A modified capacity is determined, wherein a capacity is defined by a total of available channel coding elements per transmission time interval on a channel dedicated for transmitting the control information. In addition, a quantity of communication terminals is selected for being provided with control information on the channel dedicated for transmitting the control information by accepting a further communication terminal to the quantity if the total sum of channel coding elements per transmission time interval required to transmit control information to each communication terminal of the quantity including the further communication terminal does not exceed the modified capacity, and by otherwise rejecting the further communication terminal. | 02-16-2012 |
