A system compensates a drive over reader tire pressure measurement. The system includes a drive over reader, which includes a sensor array. A pressure indication is determined for each tire in a group of tires by the drive over reader. A recommended cold pressure for the tires is provided. An adjusted recommended pressure for the tires is determined from the pressure indication and the recommended cold pressure, and accounts for temperature effects on the tires. An adjusted low pressure threshold is set at a predetermined level below the adjusted recommended pressure. A notice is generated by the drive over reader for each tire that includes an adjusted recommended pressure below the adjusted low pressure threshold.

A device for measuring a liquid level inside a tire that include two electrodes that are designed to be positioned inside the tire in such a way that they can be immersed inside the liquid that the tire may contain, and an electric circuit that is electrically connected to these electrodes. The device is designed to measure an electric property of the liquid between the electrodes while the intensity of the electric property depends on the liquid level inside the tire. The electric circuit is designed to output an electric value for the measured electric property as an output signal that can be used to calculate the level of the liquid inside the tire.

Methods, apparatuses, computer program products, systems for estimating a tire operating efficiency and range of an electric vehicle are disclosed. In a particular embodiment, a method includes determining a tire load parameter for a tire based in part on a tire deformation parameter generated by a tire mounted sensor (TMS); determining a coefficient of rolling resistance parameter for the tire based in part on a tire pressure measurement and a linear velocity measurement; and determining, based on the tire load parameter and the coefficient of rolling resistance parameter, a force of rolling resistance parameter for the tire.

An apparatus and method include, among other things, providing a plurality of sensors for a tire pressure monitoring system where each sensor is associated with tire parameter properties and has sensor parameters. Each sensor has a unique initial identification. A new unique identification is automatically generated for each sensor to replace the initial identification in response to a predetermined condition that is associated with at least one sensor parameter.

Launching lighter-than-air craft, such as stratospheric balloons, includes filling an envelope with lift gas. Depending on the size and configuration of the envelope, inflation can place excess tension on one or more points along the envelope. This tension can cause undue stress on the material, which can adversely impact the ability of the lighter-than-air craft remaining aloft for long periods of time. Aspects of the technology employ a load cell to measure tension as the envelope is filled with lift gas. Information from the load cell is used to modulate one or more elements of a launch rig to regulate the tension during fill. The load cell may be mounted in proximity to one or more attachment points between the envelope and the launch rig. The load cell readings are cross-referenced with the amount of lift gas in the envelope, and the modulation is adjusted according to this information.

A tire with printed shear sensors includes a pair of bead areas and a ground-contacting tread disposed radially outwardly of the pair of bead areas. A pair of sidewalls includes an inboard sidewall extending from a first one of the bead areas to the tread and an outboard sidewall extending from a second one of the bead areas to the tread. A carcass extends toroidally between each of the bead areas radially inwardly of the tread, and an innerliner is formed on an inside surface of the carcass. A pair of resistive shear sensors is printed on the innerliner, including a first shear sensor printed in a sidewall zone of the inboard sidewall and a second shear sensor printed in a sidewall zone of the outboard sidewall.

A device for measuring a pressure in a pressurized vessel with an at least partially flexible wall. The device includes a sensor head and a device for pressing a contact surface of the sensor head against the wall. The sensor head has a detection region of the contact surface and a support edge that surrounds the detection region and is arranged in a continuation of the contact surface. A detection device is provided in the detection region for detecting a measured value for a force or pressure. An evaluation unit evaluates a progression of the measured value during a movement of the sensor head relative to the wall. A contact measured value p* is determined from a portion of the progression indicating that the pressure acting on the detection region is at least substantially equal to the pressure acting on the support edge. A pressure value is assigned to the contact measured value p*.

A tire with printed strain sensors includes a pair of bead areas and a ground-contacting tread disposed radially outwardly of the pair of bead areas. Each one of a pair of sidewalls extends from a respective bead area to the tread. A carcass extends toroidally between each of the bead areas radially inwardly of the tread, and an innerliner is formed on an inside surface of the carcass. A pair of resistive strain sensors is printed on the innerliner, and includes a first strain sensor printed on the innerliner at an inboard rim flange area and a second strain sensor printed on the innerliner at an outboard rim flange area.

A removable pressure sensor assembly senses a pressure in an elastically deformable tube conveying blood in an extracorporeal circulator. The assembly includes a main body portion 31 and a pressure measurement element 40 disposed in main body portion 31. Main body portion 31 has a base portion 32 with a tube mounting recessed portion 34 such that an intermediate part of a tube 11 is removably fitted such that tube 11 is elastically deformed. Pressure measurement element 40 is exposed to tube 11 so that it measures a pressure of blood inside tube 11. A lid portion 33 holds tube 11 inside tube mounting recessed portion 34 by selectably closing recessed portion 34 of the base portion. Tube mounting recessed portion 34 has a rectangular cross section, and a width L of the rectangular cross section is set to be smaller than an external dimension D of tube 11.

An example system comprises a force sensing device and signal conditioning circuitry configured to be electrically coupled to the force sensing device. The example system further comprises a housing configured to enclose the force sensing device and the signal conditioning circuitry. The housing comprises a snap structure configured to attach the housing to a base plate and retain the force sensing device and the signal conditioning circuitry in the housing.
