Abstract: Systems and methods are provided for a bladeless radiator cooling fan. In one example, a system may include a plurality of bladeless entrainment discs surrounded by a shroud, each bladeless entrainment disc including a hollow central opening that enables unrestricted ambient airflow through the cooling fan, and a source fan for providing airflow to the bladeless entrainment that is encased by a housing. In this way, airflow through the bladeless radiator cooling fan may be increased, decreasing powered fan usage and decreasing fan noise.

Abstract: A system and method for monitoring sensors via surveillance cameras is disclosed. In the system, surveillance cameras generating image data of scenes, where the sensors are included in the scenes. The sensors detect information concerning the scenes and encode the information so that it can be derived from the image data. Preferably, the sensors encode the information concerning the scenes by modulating a visible light source, the signals of which are captured within the image data by the cameras. An analytics system then analyzes the image data and decodes the information from the sensors encoded within the image data. Preferably, an integrated analytics system of the cameras executes the analysis. Exemplary sensors include sensors for detecting temperature, moisture, audio/voice, and product selection in a retail premises.

Abstract: Systems and methods are provided for coupling a robotic surgical tool with a tool driver of a robotic surgical system via a sterile barrier disposed between the tool and the driver. The tool has an elongate shaft and an end effector coupled thereto, as well as a mating interface member having a plurality of independently movable portions and a plurality of coupling features disposed about a perimeter of an outer wall of the mating interface member. The coupling features are configured to reversibly engage with a proximal end of a corresponding actuation member from a plurality of actuation members of the tool driver. The coupling features reversibly engage with the proximal ends of the actuation members so as to allow the actuation members to move in proximal and distal directions independently from one another to thereby control operation of the end effector.

The housing can have at least partially disposed within it substantially cylindrical, longitudinally expandable bellows, each being configured to encompass and mate with a proximal portion of a corresponding one of the plurality of actuation members. In some cases, the sterile barrier can have a plurality of sterile barrier couplers each having a first portion configured to engage with an actuation member of a tool driver, and a second portion configured to engage with a tool actuation member of a surgical tool.

Abstract: A controller opens or closes a valve in response to the ambient temperature crossing a threshold value, for example to prevent the continued supply of water to pipes that might have frozen and burst. An output shaft (4) acts on a stem of the valve to rotate it between the open and closed positions. A clock spring (8) biases the output shaft towards one of those positions but is restrained by a latch (28) until a thermal actuator (30) operates mechanically to release the latch in response to a change in temperature. The latch may be a pawl (28) acting on a ratchet gear (22) that allows the output shaft (4) to rotate in one direction but not the other. The ratchet gear (22) may be mounted on an input shaft (14), which is connected to the output shaft (4) through a gear train (16-19) to give a mechanical advantage when turning the output shaft (4) against the force of the spring (8).

Abstract: A smart lower end system that can detect multiple events and failures during the generation of pressure pulses by a pulser is disclosed. Pulser failures may occur if the pilot valve fails to fully close or open, if the signal shaft fails to move and close pilot valve orifice, or if movement of the pilot valve or signal shaft is restricted. The components of the smart lower end system may cycle between sleep and wake states to allow for low power operation.
