Abstract: Distinctly keyed male-female couplers are pneumatically connected to medical ventilator by distinct lines carrying pulsatile gas or sensory signals. Ventilator-mounted female coupler has entranceway cavity and larger receiving cavity delimited by catch edge. Male fence-forming longitudinal winglets extend from sealing plate carry terminal end convexities which latch onto catch edge. Winglets move inward due to larger fence circumference than entranceway and seat on catch. Winglets placed in tension due to locking length less than entranceway span, then convert force into sealing compressive force between sealing plate and female tube end. Conjoining male tube bayoneted and sheathed by projecting female tube, resulting in another gas seal. Two compressive seals formed between male distal port and pneumatic line. Extending male key(s) on winglet insertable into matching female slots. Convexities block insertion of non-matching couplers set due to interference by convexities on female on entranceway edges.

Abstract: A snow plow and mount frame assembly permits an operator to attach and detach a snow plow to and from a mount frame secured to a vehicle, without the operator exiting a cab of the vehicle. The assembly comprises a mount frame, a snow plow frame, a plow blade, a first actuator for pivoting the A-frame relative to the lift frame, a latch mechanism, and a second actuator to either latch or unlatch the latch mechanism. When the vehicle is driven toward the snow plow the snow plow frame mates with the mount frame and an electrical connection is made between the vehicle electrical system and at least the first actuator without manual manipulation. The second actuator is energized to either latch the latch mechanism thereby securing the snow plow frame to the mount frame or unlatch the latch mechanism thereby freeing the snow plow frame from the mount frame.

Abstract: A coupler for connecting a tank to a receptacle includes a housing, a probe configured to translate longitudinally within the housing, and a handle assembly configured to cause the probe to translate within the housing. The handle assembly is movable between a decoupled position, a coupled position, and a venting position. The coupler includes a ball cage, a plurality of balls disposed in the ball cage, and a slidable sleeve coupled to the probe and configured to translate longitudinally with the probe. The slidable sleeve is configured to slide in a first longitudinal direction to cause the plurality of balls to translate radially to lock the coupler to the receptacle. The slidable sleeve includes a collar defining a plurality of channels that are positioned radially and extending axially along the collar and configured to receive bearings of the receptacle in the coupled position and the venting position to prevent rotation.

The coupler can also include a slidable sleeve coupled to an outer surface of the probe and configured to translate with the probe in the longitudinal direction, the sleeve including a collar configured to engage the receptacle in the coupled and uncoupled positions to prevent rotation of the coupler with respect to the receptacle when the two components are engaged to one another.

Abstract: A snow plow and mount assembly has a mount frame, an A-frame, a lift frame, a plow blade, an actuator, arms, receivers, recesses, hitch pins, a latch mechanism, and a latch lever. The elements are arranged such that the vehicle is driven toward the snow plow so that the arms are received in the receivers, the actuator is energized to pivot the lift frame relative to the A-frame so that the hitch pins are received in the recesses, and the lever is moved to move the latch mechanism to the latched position. The snow plow frame is thereby removably secured to the mount frame.

Abstract: A sensing and processing electronic circuit includes a sensing array having a plurality of sensing elements each having a sensor configured to produce an output signal in response to detection of an environmental parameter. The circuit includes a triggering unit configured to generate a trigger signal that causes an action to occur. The trigger signal is generated based on selected activated sensing elements satisfying one or more specifiable conditions. A sensing element is activated when a characteristic value based on the output value of the sensing element crosses one or more thresholds so that the characteristic value is above, below, within or outside of a specified range of values or when a difference value between the characteristic value and a previous or template value of the sensing element crosses one or more thresholds so that the difference value is above, below, within or outside of a specified range of values.

Abstract: A dynamic rollover zone detection system that is easily attached to mobile machinery and dynamically detects a rollover zone around the mobile machinery. The system detects humans and objects within the rollover zone using one or more pre-trained machine learning models in order to prevent accidents and potential collisions between machinery and people or objects in the rollover zone. If a human or obstacle is identified in the rollover zone, an alert or warning is provided and/or the mobile machinery is disabled.

Abstract: A receptacle for conveying fluid is disclosed. An example receptacle includes a main body defining an inlet and an outlet, a spring retainer disposed in the main body, a valve seat disposed in the main body, and a poppet configured to slide between a closed position and an open position. The poppet is slidably engaged with the spring retainer between the closed position and the open position and is engaged with the valve seat in the closed position. The example receptacle also includes a spring engaged with the spring retainer and the poppet to bias the poppet to engage the valve seat in the closed position. The spring retainer, the valve seat, the poppet, and the spring are removable from the main body via the inlet without disassembling the main body.

Abstract: A method and system using sensors and a deep neural network to control a treadmill based on user movement on the treadmill. Training data is collected to improve performance in a variety of typical as well as atypical treadmill activities to provide data with which to train a neural network for the task of controlling the treadmill. The method and system includes one or more sensors that obtain user movement and position data while the user is on the treadmill. A command unit (CU) stores the pre-trained neural network and receives the user movement and position data obtained by the one or more sensors. The CU determines the motion commands to provide to the treadmill based on the real-time data received from the sensor(s) and processed through the pre-trained neural network.
