A sensor device for measuring a concentration of a substance within a sample comprises a sensor comprising an optical transmission member having a first end and a second end, the second end having a tip portion attached thereto and an active material incorporated within the tip portion, the tip portion adapted to be inserted into a sample, the active material capable of interacting with a substance within a sample, a light source coupled to the first end of the sensor for emitting a beam of light into and through the sensor and into a sample, the emitted beam of light having a wavelength and the active material interacting with a substance within a sample to change the wavelength of the emitted beam of light to produce a reflected beam of light and the sensor for transmitting the reflected beam of light out of the second end thereof, an optical detector for receiving the reflected beam of light from the second end of the sensor for producing a signal indicative of the reflected beam of light, and a processor for receiving the signal indicative of the reflected beam of light and for processing the signal to determine the concentration of a substance within a sample.

A gate opener has a gate that rotates between an open and a closed position in order to allow or retard ingress and egress through the gate. A plate is secured to the ground while a motor is secured to a post of the gate and is rotatably secured to the plate. Activation of the motor causes the post to rotate and thereby swing the gate open. Subsequent activation of the motor causes the post to counterrotate and thereby swing the gate closed. Appropriate limit switches delimit the arc of travel of the gate.

A clip of the present invention comprises a unitary body having an intermediate section and a first pair of opposing arms with each of the arms having an end portion, the body having an interior surface and an exterior surface, a second pair of opposing arms formed on the exterior surface of the body, each of the second pair of opposing arms having an end portion with the second pair of opposing arms being located between one of the first pair of opposing arms and the intermediate section.

A diaper bag having an integral changing pad is disclosed which comprises a bag having an interior compartment with the bag having a top portion and a bottom portion, a cover for covering the interior compartment with the cover attached to the top portion for folding the cover over the top portion of the bag, and a changing pad having a first section connected to a second section and the second section connected to the bottom portion with the first section and the second section for being folded up in the interior compartment or unfolded out of the interior compartment.

A body limb movement limiter restrains the movement of a person's arm so as to protect the person's shoulder or restrains the movement of a person's lower leg with respect to the upper leg so as to protect the person's knee. The device uses a housing having a reel disposed therein with a tether attached thereto and a shear thickening non-Newtonian fluid disposed within the housing so that the fluid acts on the reel during a payout procedure of the tether. The housing is attached to a strap secured about the torso of the person while the free end of the tether is secured about the person's arm. Alternately, a pair of arms are pivotally secured to each other within a housing having the non-Newtonian fluid therein for limiting movement of one arm with respect to the other.

A wood joint is disclosed which comprises a first heading having a first profile comprising an upper lobe, a lower lobe, and a valley section intermediate the lobes, a second heading having a second profile comprising an upper socket, a lower socket, and a ridge section intermediate the sockets, and the first profile for engaging the second profile for securing the headings together.
