A diagnostic apparatus for a fluidic actuator, in particular a fluidic valve drive, which has an actuator element displaceable into different positions (x1, x2, xp1, xp2), wherein the diagnostic apparatus is configured to provide a first break-away pressure measured value (pi1) for a first position of the actuator element. The diagnostic apparatus is further configured to determine, based on the first break-away pressure measured value (pi1) and break-away pressure reference information (pri) stored in the diagnostic apparatus, a first break-away pressure prediction value (pp1) for a first prediction position (xp1) of the actuator element, the first prediction position being different from the first position (x1).

A communication device, method and computer program product enable reduced polling of a barometric sensor, which reduces power consumption and sensor calibration drift. A controller of a communication device determines at least one of received signal strength and direction of respective broadcast signals from local network node(s) positioned within a building to provide a local coverage area. The controller determines a location of the communication device in relation to the local network nodes in response to determining the received signal strength and/or the direction of the respective broadcast signals. The controller determines current altitude data related to a current barometer reading of the barometric sensor. The controller compares the current and the historical altitude data associated with past reading(s) at the location. In response to determining that a difference between the historical and the current altitude data is greater than a threshold distance, the controller calibrates the barometric sensor.

The present calibratable tire gauge has a first unit nose piece and a second unit nose piece located partially within a main outer enclosure of the gauge. A clicker mechanism located may allow a user to utilize a special tool to unlock the second unit nose piece with respect to the first unit nose piece and immobilize the second unit nose piece with respect to the main outer enclosure. Once unlocked, a user may twist the scale bar of the gauge to move the first unit nose piece independent from the second unit nose piece. As a result, the measured pressure on the scale bar is altered as a result of the read line being lowered or raised with respect to the main outer enclosure.

Aiming to more easily perform calibration of a sensor output from a pressure sensor, the calibration being necessitated due to the occurrence of sedimentation, a resonance point measurement unit (122) measures a resonance point of a diaphragm (112) on the basis of the result obtained by performing measurement of a constant pressure using the pressure sensor while a power supply frequency is changed, a characteristic calculation unit (123) calculates, on the basis of the measured resonance point, an elastic modulus of the diaphragm (112) at the time of the measurement of the resonance point, and a correction unit (124) calculates a corrected sensor sensitivity resulting from correcting a sensor sensitivity of a sensor chip (101) on the basis of the elastic modulus calculated by the characteristic calculation unit (123).
