Abstract: An electronic device cover system that includes an electronic device cover engageable with an electronic device, a gas sensor coupled to the electronic device cover, and a control circuit communicatively coupled to the gas sensor and communicatively engageable with an electronic device. When the gas sensor detects a presence of a target gas, the control circuit receives a signal output by the gas sensor and outputs a signal receivable by an electronic device.

Abstract: A breath sampling device including a housing having a fluid inlet positioned at a fluid inlet end, a fluid outlet positioned at a fluid outlet end, a fluid channel extending between the fluid inlet and the fluid outlet, and a sensor fluidly coupled to the fluid channel. The sensor is structurally configured to detect a presence of a target gas in a gas sample and a filter assembly fluidly coupled to the fluid channel and positioned between the fluid inlet and the sensor. The filter assembly is structurally configured to absorb heat, water vapor, or a combination thereof.

Abstract: A fixation device comprises a first clamping member having an adjustable clamping collar and a first curved support portion attached to the adjustable clamping collar. The first clamping member is adapted to receive a digit. The first curved support portion is adapted to support an inferior surface of a proximal phalanx of the digit. A distal member is adjustably attachable to the first clamping member. The distal member has a second curved support surface adapted to support an inferior surface of a distal phalanx of the digit and a curved distal end adapted to apply a compressive force in a proximal direction to a distal end of the distal phalanx.

Abstract: A printed gas sensor is disclosed. The sensor may include a partially porous substrate, an electrode layer, an electrolyte layer, and an encapsulation layer. The electrode layer comprises one or more electrodes that are formed on one side of the porous substrate. The electrolyte layer is in electrolytic contact with the one or more electrodes. The encapsulation layer encapsulates the electrode layer and electrolyte layer thereby forming an integrated structure with the partially porous substrate.

Abstract: A printed gas sensor is disclosed. The sensor may include a porous substrate, an electrode layer, a liquid or gel electrolyte layer, and an encapsulation layer. The electrode layer comprises two or more electrodes that are formed on one side of the porous substrate. The liquid or gel electrolyte layer is in electrolytic contact with the two or more electrodes. The encapsulation layer encapsulates the electrode layer and electrolyte layer thereby forming an integrated structure with the porous substrate.

Abstract: A glass manufacturing apparatus is described herein that comprises a forming device configured to produce a glass ribbon and a pull roll device which draws the glass ribbon downward from the forming device. The pull roll device has a first roll apparatus, a second roll apparatus, and a third roll apparatus. The pull roll device is configured to at least independently operate the first roll apparatus and the second roll apparatus such that at least one of a first upstream pair of draw rolls rotates with a substantially constant torque and at least one of a first downstream pair of draw rolls rotates with a substantially constant angular velocity. In further examples, methods of manufacturing a glass ribbon are provided.
