Abstract: A pipe system includes a pipe for containing a pipe flow therethrough having a first flow rate, a sampling tube coupled in fluid communication to the pipe for receiving and containing a portion of the pipe flow therethrough, for interacting with the portion of the pipe flow therethrough so as to form a second flow rate of the portion of the pipe flow being an amplification of the first flow rate, and for returning the portion of the pipe flow to the pipe, and a sensor for sensing the second flow rate and for transmitting a signal being a function of the second flow rate.

Abstract: A postural state attitude monitoring, caution, and warning system includes a multiple axis accelerometer carried by a node for generating output signals that are a function of positional orientation of the node along a path of attitude displacement of the node extending from a reference position of the node to a caution position of the node, and from the caution position of the node to a warning position of the node, and a signal device operatively coupled to the multiple axis accelerometer for issuing a caution signal in response to a caution positional state of the node at the caution position of the node and distally therebeyond to inside of the warning position of the node, and for issuing a warning signal different from the caution signal in response to a warning positional state of the node at the warning position of the node and distally therebeyond.

Abstract: An assistive walker for assisting a user in going on foot and for reinforcing recommended walker use technique includes a walker frame including opposed leading and trailing ends formed between opposed handled and footed ends and that together define a user-receiving area extending from the trailing end of the walker frame to the leading end of the walker frame, and the walker frame is for supporting a user in the user-receiving area and aiding ambulation thereof. The walker frame is formed with a motion sensor apparatus including a motion sensor assembly to detect user movement at the user-receiving area, and a signal device operatively coupled to the motion sensor assembly to emit the signal in response to a substantial lack of detected user movement at the user-receiving area.

Abstract: A vehicle assembly includes a two-wheeled vehicle including a frame having opposed sides, opposed front and rear ends, and a front wheel mounted for rotation to the frame proximate to the front end of the frame positioned in front of an opposed rear wheel mounted for rotation to the frame proximate to the rear end of the frame and that is substantially in-line with respect to the front wheel. A member is carried by the frame of the vehicle between the front and rear wheels and has end portions disposed adjacent to the respective sides of the frame. A wheeled stabilizer assembly is carried by each of the end portions of the member to wheelingly interact with the ground over which the vehicle is driven along the sides of the frame proximate to the front and rear wheels of the vehicle.
