| 20110066322 | ESTIMATION OF THE LOAD OF A VEHICLE - A method, an apparatus and a computer program product for estimating the current load of a vehicle wherein a filter bank including a filter for different weight classes, each filter implementing a vehicle model for estimating the current mass of the vehicle. Based on vehicle data indicative of a current driving situation of the vehicle, and filter parameter specific for the respective weight class, each filter provides a load estimation value as filter specific estimation of the current load of the vehicle. | 03-17-2011 |

| 20080303703 | Cross-Coupled Switched Capacitor Circuit with a Plurality of Branches - A cross-coupled switched capacitor circuit that has two branches. During a first phase for the first branch, an input voltage is provided that causes charge to move through a resistor and to be placed onto a plate of the capacitor within the branch. An equivalent amount of charge is transferred to an output node. The output node may be a summing node of a sigma-delta modulator. The summing node is one of the inputs to an operational amplifier that is part of the integrator of the sigma-delta modulator. The resistor and the capacitor in the first branch define an RC circuit and corresponding RC time constant. During the first phase, the capacitor does not reach a fully settled voltage for a desired resolution. During the second phase, the capacitor in the first branch of the circuit is set to a defined voltage. The defined voltage may be the settling voltage had the capacitor been allowed to settle during the first phase. The second branch of the switched capacitor feedback circuit operates similar to the first branch, but on opposite phases. By not requiring the voltage to settle during the first phase, power can be conserved, since the integrator of the sigma-delta modulator does not need to operate as fast with respect to movement of charge. | 12-11-2008 |

| 20120110218 | Auto-Detection and Mode Switching for Digital Interface - A method of operating a microphone system includes the steps of monitoring an I/O terminal to detect whether a signal on that terminal achieves a pre-defined logic level during a monitoring period. The I/O terminal and a second I/O terminal are configured to one of a hardware mode or a communications-bus mode depending on whether the pre-defined logic level is detected. A microphone system includes two I/O terminals and an automatic detection and mode switching circuit, as well as a communications bus interface circuit and a hardware control circuit. The mode automatic detection and mode switching circuit couples the two I/O terminals to either the communications bus interface circuit or the hardware control circuit in response to the logic level detected on one of the I/O terminals during a monitoring period. | 05-03-2012 |
| 20120243559 | Synchronization, Re-Synchronization, Addressing, and Serialized Signal Processing for Daisy-Chained Communication Devices - Techniques for use in a data communication system having a number of communicatively coupled device include techniques for synchronization and re-synchronization of frame and bit clocks, techniques for assigning device address, techniques for dynamically controlling transmit power based on the number of devices, and techniques for serialized signal processing. | 09-27-2012 |
| 20120243560 | System, Apparatus, and Method for Time-Division Multiplexed Communication - A simplified bus arrangement using only three signal lines allows TDM data to be conveyed to or from a number of slave-only devices without the use of separate command line(s) and without any of the slave-only devices having to operate as a bus master or even support a master operating mode. | 09-27-2012 |

| 20100310096 | Switchable Attenuation Circuit for MEMS Microphone Systems - A switch control circuit monitors a signal produced by a MEMS or other capacitor microphone. When a criterion is met, for example when the amplitude of the monitored signal exceeds a threshold or the monitored signal has been clipped or analysis of the monitored signal indicates clipping is imminent or likely, the switch control circuit operates one or more switches so as to selectively connect one or more capacitors to a signal line from the microphone, i.e., so as to connect a selected capacitance to the signal line to attenuate the signal from the microphone and, therefore, avoid clipping. The switches may be MOSFET, MEMS or other types of switches co-located with the microphone in a common semiconductor package. Similarly, the capacitors, a circuit that processes the signals from the microphone and/or the switch control circuit may be co-located with the microphone in a common semiconductor package. | 12-09-2010 |
| 20110142261 | MEMS Microphone with Programmable Sensitivity - A control circuit monitors a signal produced by a MEMS or other capacitor microphone. When a criterion is met, for example when the amplitude of the monitored signal exceeds a threshold or the monitored signal has been clipped or analysis of the monitored signal indicates clipping is imminent or likely, the control circuit automatically adjusts a bias voltage applied to the capacitor microphone, thereby adjusting sensitivity of the capacitor microphone. | 06-16-2011 |

| 20130145577 | VACUUM CLEANER FLOOR SEAL - A vacuum cleaner suction head having a housing, one or more support to support the housing on a surface to be cleaned, a suction inlet and front and rear sealing plates. The front and rear sealing plates extend along the front and rear edges of the suction inlet, respectively. the sealing plates are movable between raised positions in which the lower surfaces of the plates are close to the housing, and lowered positions in which the lower surfaces of the plates are remote from the housing. The front and rear plates are movable from the lowered position to the raised position by contact with debris on the surface to be cleaned. | 06-13-2013 |
