A system in accordance with the present disclosure comprises a sensor and an information processing apparatus that includes processing circuitry. The sensor is installed on a surface so that a detection direction of the sensor is at a non-zero angle from a line normal to the surface. The processing circuitry is configured to communicate with the sensor, calculate a position of a detection area, in which the sensor detects an object in a predetermined space, according to the non-zero angle and a location of the sensor on the surface, and create correspondence information that associates an area of the predetermined space with the detection area.

System, information process apparatus and information processing method

A device control system includes a detecting apparatus configured to detect an object in a predetermined space, and an information processing apparatus configured to control an illuminating apparatus based on a detection result of the object. The device control system includes an obtaining unit configured to obtain, from the detecting apparatus, information relating to an illuminance in the predetermined space; and a control unit configured to control, when the illuminance in the predetermined space falls below a first targeted illuminance, the illuminating apparatus so that the illuminance in the predetermined space becomes a second targeted illuminance that is greater than the first illuminance.

Device control system, information processing apparatus, and non-transitory recording medium

A human-body detecting device includes a first sensor and a control unit. The first sensor outputs a first signal according to a distance between the human-body detecting device and a user. The control unit finds a first weighted average of first signals weighted with a first weight and a second weighted average of the first signals weighted with a second weight different from the first weight, and detects, when a difference between the first weighted average and the second weighted average has exceeded a predetermined value, that the user is located within a predetermined range from the human-body detecting device.

Human-body detecting device, image forming apparatus, human-body detecting method, and computer program product

A processing apparatus that an uninterruptible power supply system supplies power to and carries out a process. The processing apparatus includes an electric energy amount determination part that determines, based on a charged amount of electric energy in the uninterruptible power supply system, an amount of maximum electric energy that the uninterruptible power supply system can supply; and a function selection part that selects, depending on the amount of maximum electric energy, functions that can be used for carrying out the process.

Processing apparatus, image forming apparatus, processing method and computer readable information recording medium

A fixing device includes: a heat generating rotating member including a heat generating layer; an exciting coil to inductively heat the heat generating layer; a degaussing coil generating an electrical current in response to a magnetic flux generated by the exciting coil and generating a magnetic flux in an opposite direction; an exciting coil controller configured to control energization of the exciting coil by using PWM signals; a degaussing coil controller determining necessity of switching the degaussing coil and to control energization of the degaussing coil. When the degaussing coil controller switches ON/OFF state of the degaussing coil, the exciting coil controller controls ON time periods of the PWM signals so as to be within a range from minimum to maximum values of the ON time periods of the PWM signals corresponding to the ON/OFF state of the degaussing coil stored in a storage unit.
