Sensor multiplexing in actuation systems comprising active-material actuators

摘要

A system, method, and computer storage configured for determining period-ending positions of multiple parts movable by select actuation of corresponding active materials. The operations include receiving, from a work-source sensor, work-source input indicating a distance moved by the work source and a direction of the movement, and determining, based on the work-source input and a first and second status histories, corresponding to a first and a second part, respectively, first and second distances travelled by the parts, respectively. Operations also include calculating, based on the first and second distances determined and first and second period-starting positions, corresponding to the first and second parts, respectively, first and second period-ending positions for the first and second parts, respectively.

1. A system, comprising:
a single work-source sensor for detecting a distance moved by a work source and a direction of movement; a processor; and a computer-readable medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, for determining period-ending positions of multiple parts movable by select actuation of corresponding active materials, the operations comprising:
receiving, from the work-source sensor, work-source input indicating the distance moved by the work source and the direction of the movement;determining, based on the work-source input and a first status history, corresponding to a first part of the multiple parts, a first distance travelled by the first part;determining, based on the work-source input and a second status history, corresponding to a second part of the multiple parts, a second distance travelled by the second part;calculating, based on the first distance determined and a first period-starting position, a first period-ending position, wherein the first period-starting position represents a position of the first part of the multiple parts at a start of a corresponding period, and the first period-ending position represents a position of the first part at an end of the period; andcalculating, based on the second distance determined and a second period-starting position, a second period-ending position, wherein the second period-starting position represents a position of the second part at the start of the period, and the second period-ending position represents a position of the second part at the end of the period.
