摘要： A transponder measures temperatures and pressure within a pneumatic tire. A temperature count is transmitted, which is a function of temperature. A pressure count is transmitted, which is a function of both temperature and pressure. The pressure is determined by dividing the temperature count by the pressure count. Within the transponder, a timing generator generates a first timing window during which temperature is measured and a second timing window during which pressure is measured; a temperature register captures first data indicative of the temperature within the tire; a pressure register captures second data indicative of the pressure within the tire; and a modulator circuit impresses the first data as a first portion of a data stream on a signal output by the transponder, and impresses the second data as a second portion of the data stream on the signal output by the transponder. An oscillator outputs a signal having a first frequency which is indicative of the temperature within the tire during the first timing window, and having a second frequency which is indicative of the pressure within the tire during the second timing window. A register/counter circuit counts the oscillations of the oscillator signal during the first timing window to capture the first data in the first register, and counts the oscillations of the oscillator signal during the second timing window to capture the second data in the second register.

摘要： A radio frequency (RF) transponder (200) capable of measuring parameters associated with an object and transmitting data to an external reader/interrogator (106, 400). In use with a pneumatic tire (104), the transponder measures temperature and pressure within the tire. The transponder includes circuitry (226) for controlling windows of time (WT and WP) during which real-time temperature and pressure measurements are made, and for storing (236) calibration data, transponder ID number and the like, and for transmitting this information in a data stream (FIG. 3C) to the reader/interrogator. An excessive temperature condition may also be sensed (MTMS 218) and included in the data stream. The circuitry of the transponder is preferably implemented on a single IC chip (204), using CMOS technology, with few components external to the IC chip. The transponder is preferably passive, deriving its operating power from an RF signal provided by the exernal reader/interrogator. Data (NT) indicative of temperature and data (NP) indicative of pressure are both transmitted to the reader/interrogator, along with calibration data. A calibration data stored by the transponder and transmitted in the data stream is a slope of NT/NP, or the “ratioed” response of the temperature count divided by the pressure count, which is determined during calibration of the transponder.

摘要： A method (650) of calibrating a transponder (200, 604) capable of measuring temperature data (NT) and pressure data (NP) in an object (e.g., a tire, (104)) and transmitting a data stream (FIG. 3C) to an external reader/interrogator (106, 400). The transponder includes memory (238) for storing measurements, calibration data (662), transponder ID number and the like. Since the transponder combines temperature and pressure information in the “pressure” data, the ratio NT/NP is a direct indicator of pressure only, and is also relatively insensitive to transponder power variations. The calibration method employs a calibration chamber (602) containing reference pressure (614) and temperature (612) sensors. The transducer to be calibrated is placed in the chamber and exposed (652) to a number of predetermined temperatures and pressures (as measured by the reference sensors) at a number of calibration points. At each calibration point, a temperature reading (NT) and a pressure reading (NP) sensed by the transponder are recorded along with the reference temperature and pressure. Prom these readings and reference measurements the calibration constants (NT25, mT, NT/NP700,25, mP) are calculated (658).

摘要： A response-adjustable temperature sensor (306, Rext), particularly for a transponder (102, 200, 400) capable of measuring one or more parameters (e.g., temperature, pressure) and transmitting a data stream (FIGS. 3C, 4B) to an external reader/interrogator (106). The transponder typically operates in a passive mode, deriving its power (Vxx, Vcc, Vdd) from an RF interrogation signal received by an antenna system (210, 410), but can also operate in a battery-powered active mode. The transponder includes memory (238, 438) for storing measurements, calibration data, programmable trim settings (436b), transponder ID and the like. The temperature sensor is a temperature measurement device characterized by a resistance (Rext, 216, 416, 716) and a temperature sensing circuit (306) comprising a temperature sensing transistor (Q1) which exhibits a predictable change in its base-emitter voltage due to temperature, and transistors (P1, N1, P2, N2) connected for mirroring a current (I(T)) through the temperature sensing transistor and through the resistance. The resistance may be a fixed, temperature-independent resistor or a resistance that has a resistance value that predictably varies with temperature, such as a thermistor (716). Temperature response and resolution can be adjusted while maintaining desired current levels by varying the value of the resistance and also by selecting a thermistor with a suitable temperature coefficient. User-settable trimming bits can be used to determine scaling of the transponder output. Replacing an external pressure-sensing capacitor with a fixed-value capacitor allows further flexibility in scaling of the output when only temperature readings are needed.

摘要： A method apparatus are directed to identify items disposed on the bottom shelf of a shopping cart bottom of basket (BoB). Certain aspects envision a distance measurement sensor and computing system connected to the shopping cart. A first set of distance measurements of the bottom shelf when empty is obtained via the distance measurement sensor. Next, at a checkout stand, a second set of distance measurements of the shelf are taken, which can be used to compare with the first set of distance measurements to identify if there is an object on the BoB. An alert can be provided to a checkout attendant if there is an object on the BoB.

摘要： A variable modulation index for a transponder (102, 200, 400) capable of measuring one or more parameters (e.g., temperature, pressure) in an object (e.g., a tire, (104)) and transmitting a data stream (FIGS. 3C, 4B) to an external reader/interrogator (106). The transponder typically operates in a passive mode, deriving its power (Vxx, Vcc, Vdd) from an RF interrogation signal received by an antenna system (210, 410, 710), but can also operate in a battery-powered active mode. The transponder includes memory (238, 438) for storing measurements, calibration data, programmable trim settings (436b), transponder ID and the like. Data stream transmission is preferably accomplished by PSK modulation (700) of the received RF signal, wherein the magnitude of modulation (index) is programmably varied in binary steps according to the programmed trim settings, and dynamically varied according to the level of input power in order to optimize the transmission. The transmitted signal is cleaned of noise by synchronizing a clock signal with the data stream signal.

摘要： A pneumatic tire monitoring system for monitoring pneumatic tire conditions for one or more tire/wheel assemblies mounted on a vehicle, preferably in combination with a tire pressurizing and regulating apparatus, comprises a transponder with a transmitting antenna mounted on the wheel for transmitting a signal indicating tire condition, one or more receivers with receiving antennas fixedly mounted on the vehicle, and circuitry for processing the received signals; the system characterized in that: circuitry for each transponder is on a printed circuit board within a protective housing coaxial to the hub of the wheel or wheel carrier; and each transmitting antenna is selected from the group comprising a partial loop antenna, a helical antenna, a circular dipole antenna, and a small coupling coil adjacent to an endless hoop antenna. The partial loop antenna is mounted in each housing affixed around a portion of the circumference of the printed circuit board, having an angular arc length, and comprises a serpentine portion for increasing the effective length of the partial loop antenna without also extending the angular arc length. The angular arc length and the affixed placement are determined for avoiding RF signal interference due to interaction with signal-interfering objects in the housing. Additionally, the partial loop antenna has an end portion that can be trimmed for adjusting the effective length to enable tuning of the antenna for optimum transmission at different radio transmission frequencies.
