System and method of a bed with a safety stop
First Claim
1. A system for executing a computer-based safety-action during a motor-actuated adjustable bed position adjustment, comprising:
- an adjustable bed facility comprising a computer-based controller, an actuator, and a sensor,the computer-based controller providing control of adjustable bed position adjustments,the actuator configured to adjust a height of the adjustable bed facility upon receiving a height-adjustment command from the computer-based controller, andthe sensor for determining an actuator action parameter measured value of the actuator, the computer-based controller in communicative connection with the sensor to monitor and compare the motor action parameter measured value to an actuator action parameter normal operation value range, and when the controller determines the monitored motor action parameter measured value is outside the range of the actuator action parameter normal operation value range the controller sends a safety-action command to the actuators;
wherein the sensor is adapted to continuously measure rotational position for a component of the actuator, the rotational position being interpreted by the controller as an indicator of the rotation rate of the actuator, where a less than normal rotation rate is indicative of an object obstructing the actuated motion of the adjustable bed height adjustment.

Abstract
The present disclosure concerns an adjustable bed facility including a system for executing a computer-based safety-action during a motor-actuated adjustable bed position adjustment, comprising an adjustable bed facility comprising a computer-based controller, an actuator, and a sensor, the computer-based controller providing control of adjustable bed position adjustments, the actuator configured to adjust a height of the adjustable bed facility upon receiving a height-adjustment command from the computer-based controller, and the sensor for determining an actuator action parameter measured value of the actuator, the computer-based controller in communicative connection with the sensor to monitor and compare the motor action parameter measured value to an actuator action parameter normal operation value range, and when the controller determines the monitored motor action parameter measured value is outside the range of the actuator action parameter normal operation value range the controller sends a safety-action command to the actuator.
