    摘要： A locator according to various aspects of the present invention includes a receiver and a processor. The receiver receives several signals, each signal having respective indicia of identification device presence within a respective communication pattern. The processor performs a method for determining whether a first identification device is located within a zone. The method includes the following steps performed in any order. A first step of determining, in response to receiver signals, a respective reliability of communication between the receiver and a plurality of identification devices. The plurality includes the first identification device and at least one second identification device. A first and a second communication pattern each respectively has a periphery such that communication with a provided identification device when located beyond the periphery is less reliable than communication with the provided identification device when located within the periphery. The first identification device is located within the periphery of the first pattern. Each second identification device is located beyond the periphery of the first pattern and within the periphery of the second pattern. And, the first pattern has a periphery substantially within the zone. A second step of comparing each respective reliability of communication to a respective threshold to identify validly present identification devices. And, a third step of determining that the first identification device is within the zone in accordance with whether the first identification device is validly present within the first pattern, the second identification device is validly present within the second pattern, and the second identification device is not validly present within the first pattern.

    摘要： Selected vehicle operational parameters such as tire pressure, wheel temperature and vibration are sensed by sensors mounted on wheel modules secured to the individual vehicle wheels. The sensed parameters are converted to digital format and the resulting digital data is manipulated to determine if the data falls within predetermined operating ranges. The data and information resulting from the manipulation are used to modulate an RF signal transmitted to another location on the vehicle. Additional parameters are sensed at the second location, and calculations are performed on the data received from the wheel modules and the data sensed at the second location to display operational, efficiency and safety information to the vehicle operator and to make such information available to others such as vehicle owners and maintenance personnel.

    摘要： A tire monitor includes a pressure sensor, a temperature sensor, an A/D converter, and a microprocessor. The microprocessor has a sleep mode for conserving power and an output of the microprocessor controls the power applied to the pressure sensor and to the temperature sensor. A modulator and antenna are coupled to the microprocessor for transmitting data from the tire. Coupling between a monitor and a receiver is enhanced by extending a receiving antenna downwardly from the chassis of the vehicle, e.g. from the frame of a tractor.The tire monitor is fabricated on a small printed circuit board with terminals for programming or encoding each monitor with a unique identification code during manufacture of the monitor. Terminals are also provided for disabling the transmitter with a jumper until the monitor is installed in a tire. The jumper is removed upon installation but the transmitter is further prevented by the microprocessor from transmitting until the pressure in a tire first exceeds a predetermined pressure. Transmissions occur at widely spaced intervals and the spacing depends on the content of the data. The number of times that the data is repeated within a transmission is also a function of the content of the data.

    摘要： A system includes an identification circuit, a grid antenna, a receiver, and a processor. The identification circuit includes resonant circuits formed on a substrate within a perimeter. Identification may be based on a quantity or physical arrangement of detected resonant circuits within the perimeter. One resonant circuit provides a reference signal. Any resonant circuit may be tuned in accordance with the reference signal by the addition or subtraction of reactance formed on the substrate. A capacitance of a first group of capacitors located outside a turn of an inductor is roughly equal to a capacitance of a second group of capacitors located inside the turn. Any resonant circuit may also be tuned by affixing a resonance modifying element, for example a sticker, to the identification circuit. The grid antenna provides antenna field patterns, one for each cell location. The receiver communicates with the identification circuit via the grid antenna. The processor controls the receiver according to a method including: (a) detecting a first signal at a first grid location; (b) determining an offset as a difference between a frequency of the first signal and a predetermined frequency; (c) detecting a second signal at a second grid location; (d) determining an identification in accordance with the first and second locations, the second signal, the offset determined in step (b), and any offset accomplished by a sticker; and (e) determining an orientation in accordance with the first and second grid locations.
