Automated window mechanism with releasable clutch

An automated window mechanism for a window, the window having first and second components that move relative to one another to open or close the window, the automated window mechanism comprising:

• a motor attached to the first component;
• a rack coupled to the second component;
• a transmission having an engaged state in which the motor is able to move the first component relative to the second component and a disengaged state in which the motor is unable to move the first component relative to the second component, wherein the motor drives the transmission to move the first component relative to the second component to open or close the window with the transmission in the engaged state, and wherein in the disengaged state the transmission releases the first component from the second component such that the first component is permitted to move relative to the second component without being driven by the motor;
• a memory configured to store at least one user determined endpoint defining a limit of movement of the first component relative to the second component;
• a position sensor coupled to the transmission and being configured to monitor a position of the first component relative to the second component;
• and
• a transmission switch assembly, comprising:
• a manual switch;
• a remote switch;
• and
• a switch actuator being configured to alternate the transmission between the engaged state and the disengaged state in response to an instruction received from the manual switch or the remote switch, a switch actuator sensor configured to monitor movements of the switch actuator and a memory configured to record the movements of the switch actuator as measured by the switch actuator sensor, wherein the position sensor is configured to continue monitoring the position when the transmission is in the engaged state and when the transmission is in the disengaged state, wherein when the transmission is in the disengaged state a manual movement of the first component relative to the second component is recorded by the position sensor such that the position of the first component relative to the second component is known when engaging the transmission after the manual movement of the first component relative to the second component.

An automated window mechanism, comprising:

• a motor coupled to a sliding window;
• a transmission comprising:
• a drive shaft;
• an interface gear;
• a rack attached to a window frame;
• wherein the motor and the transmission are configured to move the sliding window relative to the window frame;
• a transmission switch coupled to the transmission and having an engaged state in which the transmission couples the motor to the rack and a disengaged state in which the transmission does not couple the motor to the rack;
• a memory configured to store a first endpoint and a second endpoint defining limits of movement for the sliding window relative to the window frame;
• a transmission switch actuator configured to engage and disengage the transmission with and from the motor in response to the transmission switch;
• a sensor configured to monitor movements of the transmission switch between the engaged state and the disengaged state and a memory configured to record the movements of the transmission switch between the engaged state and the disengaged state as measured by the sensor;
• and
• a position sensor configured to monitor each rotation of the drive shaft to identify a position of the sliding window relative to the window frame, wherein the position sensor is configured to monitor the position of the sliding window relative to the window frame independent of whether the transmission is engaged or disengaged with and from the motor such that the position of the sliding window relative to the window frame is known whether the transmission is engaged or disengaged with and from the motor does not require recalibration of the first and second.
