Abstract: A holder for a bit is disclosed. The bit may include a first locking element. The holder may include a housing; a base assembly including a first hole; a second locking element partially disposed within the first hole and configured to move between a locking position in which the second locking element engages the first locking element to prevent removal of the bit, and an unlocking position in which the second locking element is spaced from the first locking element allowing the bit to be removed; and a follower assembly contained within the housing and configured to move relative to the housing and base assembly between a first position in which the follower assembly supports the second locking element in the locking position, and a second position in which the follower assembly allows the second locking element to move from the locking position to the unlocking position.

Abstract: Automatic valve actuator apparatus and valve actuator assemblies are disclosed. The automatic valve actuator apparatus may include a sensor assembly configured to detect a condition and transmit a sensor signal indicating detection of the condition, and a valve actuator assembly configured to be attached to the manual valve and to move the manual valve between open and closed positions. The automatic valve actuator apparatus may additionally include a control assembly configured to receive the sensor signal and to transmit a first control signal to the valve actuator assembly based, at least in part, on the sensor signal. The valve actuator assembly may be further configured to receive the first control signal from the control assembly and to move the manual valve toward the closed position in response to receiving the first control signal.

Abstract: Camera accessories configured to couple a camera having a camera optical axis and a scope having a scope optical axis are disclosed. Additionally, camera accessories configured to couple a smart phone having a camera with a camera optical axis and a scope having a scope optical axis are disclosed. The camera accessory may include a locking mechanism configured to selectively secure the portion of the scope to the scope-receiving assembly such that, when the camera is attached to the camera-receiving assembly and when the scope is received by the scope-receiving assembly, the camera optical axis coincides with the scope optical axis.
