An indicating device, in particular a pressure gauge, including: a basic housing including a mechanism for driving a rotating needle indicator, movable relative to a dial, an interface housing attached to the basic housing, at least one rotary screen carried by the interface housing, for locating an operating area, of which the angular position can be adjusted about the axis of the needle, a protective cover removable attached to the interface housing and making it possible, when removed, to adjust the position of the rotary screen without separating the interface housing from the basic housing.

A walk discrimination device includes: a data reception unit that receives sensor data including an acceleration and an angular velocity acquired by a sensor installed in a shoe; an acceleration determination unit that determines whether the acceleration included in the sensor data is positive or negative; an attitude angle calculation unit that calculates an attitude angle by use of the acceleration and the angular velocity included in the sensor data; an attitude angle determination unit that determines whether the attitude angle calculated by the attitude angle calculation unit has exceeded a threshold, and determines whether a peak of the attitude angle has been detected; a walk discrimination unit that discriminates a walk based on a determination order by the acceleration determination unit and the attitude angle determination unit; and an output unit that outputs a discrimination result by the walk discrimination unit.

Systems and methods for remote Proof-of-Work (PoW) generation.

A signal processing method includes a processing target signal generation step of generating a processing target signal which is a time-series signal based on a source signal which is a time-series signal output from an object, and a vibration rectification error calculation step of calculating a plurality of vibration rectification errors by performing product-sum operation processing of a first signal based on the processing target signal and a second signal based on a phase-shifted signal of the processing target signal a plurality of times by changing a shift amount.
