Example implementations relate to display adjustments. For example, a non-transitory computer readable medium storing instructions executable by a processing resource to sense a contour of an object using a sensor of a display. The instructions can cause the processing resource to determine a contour of a perimeter of the display that fits a portion of the shape of the object. The instructions can cause the processing resource to adjust the perimeter of the display to the determined contour of the perimeter via an actuator of the display.

Methods and systems for controlling pressure in a cavity of a light source are provided. One system includes a barometric pressure sensor configured for measuring pressure in a cavity of a light source. The system also includes one or more gas flow elements configured for controlling an amount of one or more gases in the cavity. In addition, the system includes a control subsystem configured for comparing the measured pressure to a predetermined range of values for the pressure and, when the measured pressure is outside of the predetermined range, altering a parameter of at least one of the one or more gas flow elements based on results of the comparing.

A micromechanical piezoresistive pressure sensor includes a diaphragm configured to mechanically deform in response to an applied load, a sensor substrate located on the diaphragm, and a number of piezoresistive resistance devices located on the sensor substrate. The piezoresistive resistance devices are arranged in a first planar array defining a grid pattern having two or more rows, each row being aligned in a first direction. The piezoresistive resistance devices are configured to be electrically connected in a number of bridge circuits, whereby the piezoresistive resistance devices in each row is electrically connected in an associated bridge circuit. A method of using the micromechanical piezoresistive pressure sensor is also disclosed.

A handheld-sized, single-hand-holdable, single-hand-operable battery-powered digital backflow prevention assembly testing gage capable of measuring a differential pressure between high and low side fluid sources, providing a capture value function for easily recording pressure values while continuing display of live pressure measurements, and providing a rate of change graph display for immediate visual indication of changes in the differential pressure being sensed.

A comparison determination unit of a hydraulic control device determines whether a characteristic abnormality occurs in at least one hydraulic sensor of an output pressure sensor and a lateral pressure sensor by comparing an output pressure detected by the output pressure sensor and a lateral pressure detected by the lateral pressure sensor. An individual determination unit determines whether the characteristic abnormality occurs in the hydraulic sensor as a determination target by individually determining whether the output pressure and the lateral pressure are out of a predetermined range. A characteristic abnormality detection unit determines the hydraulic sensor in which the characteristic abnormality occurs by using each determination result in the comparison determination unit and the individual determination unit.
