Abstract
A sheet-type device that can be arranged under a user, the sheet-type device including: a plurality of first sensors configured to acquire a weight of the user, a second sensor configured to acquire biological information of the user, and a controller configured to acquire values acquired from the first sensors and to determine a state of the user, wherein the first sensors and the second sensor are arranged in one line along a right-left direction of the user, and the second sensor is arranged between the first sensors.

A sheet-type device that can be arranged under a user, the sheet-type device comprising:
- a plurality of first sensors configured to acquire a weight of the user;
- a second sensor configured to acquire biological information of the user;
- and
- a controller configured to acquire values acquired from the first sensors and to determine a state of the user, wherein the first sensors and the second sensor are arranged in one line along a right-left direction of the user, and the second sensor is arranged between the first sensors,
- wherein the controller is configured to:
- acquire, from the first sensors, first values corresponding to the absolute amount of load and output continuously when the user is detected;
- and
- acquire, from the second sensor, second values corresponding to load variation or vibration, the output of which is stopped after the load stabilizes.
A system comprising:
- a first sheet-type device that can be arranged on a bed apparatus and in which a plurality of first pressure-sensitive sensors are arranged in a longitudinal direction;
- and
- a second sheet-type device that can be arranged on the bed apparatus and in which a plurality of second pressure-sensitive sensors are arranged in a longitudinal direction, wherein
- the first sheet-type device is arranged at a first position of the bed apparatus such that the first pressure-sensitive sensors are arranged at equally-spaced intervals along a width direction of the bed apparatus,
- the second sheet-type device is arranged at a second position of the bed apparatus such that the second pressure-sensitive sensors are arranged at equally-spaced intervals along the width direction of the bed apparatus, the second position being different from the first position and
- the first sheet-type device is configured:
- to acquire, from the second sheet-type device, values acquired by the second pressure-sensitive sensors, and
- to acquire a state of the user on the bed apparatus based on the values acquired from the first pressure-sensitive sensors and values acquired from a second acquisition device, and
- wherein the first sheet-type device further comprises a third sensor configured to acquire biological information of the user, the third sensor being arranged in one line along the width direction of the bed apparatus and being arranged between the first pressure-sensitive sensors, and
- wherein the first sheet-type device's controller is configured to:
- acquire, from the first and second pressure-sensitive sensors, first values corresponding to the absolute amount of load and output continuously when the user is detected;
- and
- acquire, from the third sensor, second values corresponding to load variation or vibration, the output of which is stopped after the load stabilizes, and acquire the state of the user on the bed apparatus based on the first values and the second values.
