| 20090219973 | Pulse modulation and demodulation in a multiband uwb communication system - In a wireless communications system, such as a multiband Ultra Wideband communications system, data is transmitted by means of the phases of pulses in multiple frequency bands. A signal is transmitted with a predetermined phase in at least one of the frequency bands for at least a part of the time, and can be used to allow accurate detection of the phases of the signals transmitted in the other frequency bands. One of the frequency bands can be designated as a reference band, and pulses can be transmitted with constant phase in the reference band. More generally, pulses can be transmitted in the other frequency bands with phases which have a known relationship with the phases of the pulses in the reference band. | 09-03-2009 |

| 20110128111 | PLANAR, MONOLITHICALLY INTEGRATED COIL - The present invention provides a means to integrate planar coils on silicon, while providing a high inductance. This high inductance is achieved through a special back- and front sided shielding of a material. In many applications, high-value inductors are a necessity. In particular, this holds for applications in power management. In these applications, the inductors are at least 5 of the order of 1 μH, and must have an equivalent series resistance of less than 0.1 Ω. For this reason, those inductors are always bulky components, of a typical size of 2×2×1 mm 3, which make a fully integrated solution impossible. On the other hand, integrated inductors, which can monolithically be integrated, do exist. However, these inductors suffer either from low inductance values, or 10 very-high DC resistance values. | 06-02-2011 |
