Title: Magnetising a dart
Inventor: YIU CHIH-HAO
IPC: H01F13/00
Filed: 2006-10-04
Abstract: An apparatus and method for magnetizing a dart 20 comprises the steps of: (a) preparing a temporarily magnetizable dart 20; (b) charging the dart with a magnet charger 30. The magnetic material of the dart 20 will then produce a temporary magnetic force. The temporary magnetic force of the dart 20 can cooperate with a magnetic induction scoring dartboard (Fig 2) to automatically create a score, and the temporary magnetism will disappear within a predetermined period of time. Therefore, the dart 20 is suitable for use in a formal dart competition, and the user is free of the adverse effect of the magnetic force. The magnet charger 30 may be a magnetising coil 33 or permanent magnet (61 or 71, Fig 8 or Fig 9) and when the charger 30 has a magnetising coil 33 may a power source 32, a control switch 34, a current direction switch 35, a charging light 36 and an aperture or receiving space 331 for the dart 20. The dart 20 can also be demagnetised by the charger 30.

Title: Calibration of a quadrature modulation transceiver by selectively modifying a signal for transmission in a loopback module
Inventor: YEN SHIN-CHIEH
IPC: H04L27/36
Filed: 2007-02-09
Abstract: A quadrature modulation transceiver (200) receives in-phase (Ir) and quadrature (Qr) components corresponding to an input signal, and generates a transmssion signal (St) by up-converting the in-phase (It) and quadrature (Qt) components using in-phase and quadrature transmitting carriers (SIt, SQt) respectively. In a calibration phase the signal St is routed via a path selector (250) to a loopback module (270), where a set of modifying parameters (e.g. phase and amplitude values) selected from a plurality of such sets are applied to St to generate a loopback signal (S Ib). The loopback signal is then sent back via path selector (260) to the transceiver, which down-converts the loopback signal using in-phase (SIr) and quadrature (SQr) receiving carriers respectively. The transceiver calibration unit (205) computes calibration parameters to correct for IQ imbalance based on the received modified loopback signal.

Abstract: A controller (1) controls an on-vehicle device having an operating member (55) operated by a driver to receive a driver's operating force and an assisting mechanism (PS) giving an assisting force to the operating member (56). This mechanism is powered by an on-vehicle battery (53). The controller detects forces applied to the device and calculates a control amount giving the assisting force to the device based on results detected by the force detector (51). The control amount is calculated every type of the applied forces (21,22,23,31) whose frequency bands are at least partly different from each other. The controller (1) drives the assisting mechanism (PS) based on the control amount and detects an operating state of the battery (53). The controller (1) adjusts the control amount such that, as the calculated battery state decreases in a powering function of the battery, the control amount for, of the applied forces, a specified force having specified frequency components is monotonously reduced (24,25,26,32).
