Abstract: A door is coupled to a door operator assembly that includes a motor operable in a first mode of operation to open the door at a pre-defined speed. The first mode of operation is overridden in response to an output of the motor reaching a minimum threshold due to a force applied to the door. In the second mode of operation, the output of the motor is adjusted to assist manual opening of the door.

Abstract: A retrofit module configured for use with a door closer having a pinion. The retrofit module generally includes a case, an output shaft, a motor, and a control assembly. The output shaft is rotatably mounted in the case, and is configured for rotational coupling with the pinion. The motor is mounted to the case, and is operable to rotate the output shaft in a door-opening direction. The control assembly is mounted to the case, and is configured to operate the motor to drive the output shaft in the door-opening direction in response to an actuating signal.

Abstract: An exemplary method involves operating a door operator coupled to a door. The door operator includes a motor operable to move the door in at least one direction and a controller operable to control the motor. The method generally involves a calibration procedure including: with the door at a first position and the door having an initial speed, initiating, by the controller, measurement of a time duration; in response to the door reaching a target speed different from the initial speed, ceasing, by the controller, measurement of the time duration; and determining, by the controller, a maximum speed based on the time duration. The method further includes performing at least one operation based upon the maximum speed.

Abstract: A dynamic energy harvesting and variable harvesting force system is disclosed. A boost converter increases a motor voltage as a motor current associated with the motor voltage propagates through the boost converter thereby generating a boost voltage associated with the changing motor current. A power storage device stores energy harvested by the boost converter when the boost voltage exceeds an energy storage threshold. A controller dynamically adjusts a harvesting force applied by the motor so that the harvesting force is relative to the force applied to the motor. The controller also dynamically adjusts the harvested energy stored by the power storage device by adjusting the charging of the power storage device, ensuring that the boost voltage threshold is maintained. The boost voltage when maintained within the boost voltage threshold enables the power storage device to store the harvested energy without impacting the harvesting force applied by the motor.

Abstract: The invention relates to methods and compositions for maintaining the pro-regenerative capacity of distal nerve segments following nerve injury.

Abstract: Communication units organized into user groups are divided into user groups that distinguish whether a member of the user group may or may not interrupt active calls. Communications will not be interrupted (303) by units that are not allowed to interrupt active calls. Communications are interrupted (304) only by units that are allowed to interrupt active calls.
