摘要： An apparatus (100) for sensing size and location of a vehicle occupant includes a conductor (110) that is electrically coupled to a voltage signal generator (612) and disposed within the seat of the vehicle. The conductor generates a periodic electric field (124). A plurality of sensor electrostatic antennas (120) is disposed adjacent the roof and is capable of sensing at least a portion of the electric field (124). A detection circuit (624) determines the size and location of a vehicle occupant based upon an amount of the electric field (124) incident on each sensor electrostatic antenna (120).

摘要： A scanning CRT display system is disclosed in which transitions of a horizontal sync signal are directly utilized to provide control signals for driving a FET (field effect transistor) power drive device which controls horizontal deflection yoke current. Protection circuitry is provided such that the FET power drive device is turned off if excessive FET through current is sensed, and protection circuitry also prevents turning on the FET drive device if an excessively high flyback voltage is present at the drain terminal of the FET device. Linearization of the horizontal deflection yoke current is provided by effectively sensing the temperature variable on resistance of the FET output drive device and providing a compensation control signal in accordance therewith, wherein this compensation control signal controls the magnetization provided by a control winding on a saturable magnetic core on which a linearity compensation coil is also wound. The linearity compensation coil and the deflection yoke are connected in series and the compensation control signal effectively reduces the series inductance of these elements so as to provide linearity compensation for horizontal deflection yoke current.

摘要： A scanning CRT control system is disclosed in which horizontal sync pulses are used to develop a pulse signal that provides an input to a transformer circuit also receiving a relatively low DC power supply input signal. The transformer circuit develops a very high DC voltage connected to a CRT screen while also providing a relatively lower voltage power supply signal that is utilized to develop the power supply signal provided to a video driver that controls beam excitation for the CRT. A compensation circuit is provided between the transformer circuit and a power supply terminal of the video driver such that a compensating signal is provided at the transformer circuit in accordance with each horizontal video scan line. The compensating signal has a frequency corresponding to the horizontal sweep frequency and a magnitude that varies in accordance with the average current loading of each individual horizontal scan line. In this manner the compensating signal will cause a variation in horizontal beam positioning so as to maintain horizontal orientation between different sequential horizontal scan lines regardless of the average beam current intensity of each of the horizontal scan lines. Preferably, the compensation circuit comprises a parallel resistor and capacitor connected in series between an output terminal of the transformer and the power supply terminal of the video driver.

摘要： A crop frost prediction system (20) is provided. The system (20) exposes a thermally radiant surface (22) to atmosphere (26) and senses the temperature of the thermally radiant surface (22). The sensed temperation, alone or in combination with other variables, is used by a processor (38) to calculate whether frost is likely to occur. The system (20) capitalizes on the understanding of the inventor that the thermally radiant surface (22) will dissipate heat (24), and thus have a lower temperature than the ambient air, under conditions of low humidity and clear night sky.

摘要： A method and system for monitoring air pressure or operational status of at least one particular tire of a vehicle facilitates ready identification of a relative mounting position of the particular tire. At least one pressure indicating signal is received (110 of FIG. 8) and is associated with a particular tire mounted at an unknown relative position on a vehicle. Physical parameter data are obtained (112) indicating physical parameter measurements at the different tires of a vehicle. The obtained physical parameter data are evaluated (114) to identify the relative mounting position of the particular tire on the vehicle. Accordingly, an operator of the vehicle may be provided with an indication (130) that an air pressure of a particular tire is less than a proper air pressure so that peak vehicle performance and necessary maintenance may be obtained. Even if the indication informs that the pressure is normal, the operator is reassured that the tires are functioning properly.
