    摘要： An RF tagging system includes an RF tag (10, 30) and an RF tag reader 80. The RF tag includes a plurality of RF resonant circuits. Each RF resonant circuit is resonant at a given RF frequency. A group of decoder RF resonant circuits (12, 32) have resonant frequencies defining one of a plurality of predetermined decoding modalities. A group of data RF resonant circuits (14, 34) have resonant frequencies corresponding to a predetermined identification code when the resonant frequencies of the data RF resonant circuits are decoded in accordance with the one decoding modality. The RF tag reader detects the resonant frequencies of the decoder RF resonant circuits and determines the one decoding modality. The RF tag reader is operative in each of the plurality of predetermined decoding modalities, detects the resonant frequencies of the group of data RF resonant circuits, and decodes the resonant frequencies of the group of data RF resonant circuits in accordance with the one decoding modality to provide the identification code. The decoder RF resonant circuits may also indicate the number of data RF resonant circuits on the RF tag. The RF tag reader determines the predetermined number from the decoder RF resonant circuits to confirm the accurate detection of the data RF resonant circuits. The RF tag reader, when selecting a decoding modality in accordance with the detected resonant frequencies of the decoder RF resonant circuits, determines various frequency bands and alters the RF tag reader frequency detection operation for accurate detection of the data RF resonant circuits.

    摘要： A motion-damping device (10) includes a piston (18) moveably disposed within a housing (16) and dividing the interior of the housing into an upper chamber (20) and a lower chamber (22). An electrorheological fluid which fills both chambers can pass from one chamber to the other chamber via at least one fluid passageway (28) formed in the piston. Each passageway, tapered to form a relatively narrow neck portion, is in close proximity to an electrode that receives an electric potential for developing an electric field within the passageway to control the viscosity of fluid in the passageway.

    摘要： Electronic circuit modules (10; 100; 400) have connector (11; 111; 411) with through pins (14, 114; 414) and a metal ground path (17) embedded therein which fit within a recess (24; 124; 424) formed by a heat sink (18; 118; 418) having a central plate portion (19) surrounded by metallic cooling fins (23). A polyimide insulating circuit base film (26; 126; 500) has conductor paths (27) and circuit components (30) on at least a top surface (28) thereof with a bottom surface (31) mounted to the top surface (21) of the heat sink plate portion (19). The connector through pins are electrically connected to the conductor paths on the polyimide base film and a cover (33;133) together with the heat sink forms an internal cavity (34; 134) for protection of the components. This structure provides a compact configuration and lower manufacturing costs for a circuit module, permits reducing RF radiation and absorption problems and permits reducing resistive connections between the through pins and the components. Also implemented are high frequency bypass capacitive networks (18, 222; 118, 325) associated with each of the conductive through pins.

    摘要： A blood pressure sensor includes a source of photo-radiation, such as an array of laser diodes. The sensor also includes a two-dimensional, flexible reflective surface. The reflective surface is nominally positioned relative to the radiation source such that the radiation travels in a direction normal to the reflective surface. The reflective surface is placed adjacent to the location on the patient where the blood pressure data is to be acquired. Radiation from the source is reflected off of the reflective surface onto a two-dimensional array of photo-detectors. Systolic and diastolic blood pressure fluctuations in the patient are translated into deflections of the patient's skin. These deflections cause corresponding deflections in the two dimensional reflective surface. The associated movement of said flexible reflective surface due to blood pulsation causes scattering patterns from said reflective surface to be detected by the two dimensional array of photo-detectors. The output from the array of photo-detectors is calibrated to blood pressure in mmHg during a calibration procedure to obtain a set of calibration relationships for one or more of the individual detectors. The calibration relationship are then used during acquisition of blood pressure data to arrive at blood pressure data.

    摘要： An anti-lock braking system for a vehicle having a plurality of wheels, and a braking system that includes a brake for braking at least one of the plurality of wheels and a brake valve for controlling a braking pressure in the brake in response to a brake valve signal, includes a plurality of wheel speed sensors for generating a plurality of input signals. A polynomial processor, in communication with the plurality of wheel speed sensors, generates a control signal based on a nonlinear polynomial function of the input signal. A post-processor generates the Brake valve signal based on the control signal so as to provide cyclic control of the braking pressure in the brake.
