Abstract: An orthopedic instrument, comprising a pair of pivotally-connected arms, extending beyond a pivot axis of a first pivot; a pair of feet mounted to ends of the pair of pivotally-connected arms; and a quadrilateral linkage configured to maintain parallelism between the pair of feet over a range of angles and to selectively alter a distance between the pair of feet.

Abstract: Analyte survey systems (100) and related techniques are provided to improve the operation of handheld or unmanned mobile sensor or survey platforms. An analyte survey system includes a logic device (112) configured to communicate with a communication module (164) and a sensor assembly (166) of a modular sensor core (160), where the communication module is configured to establish a wireless communication link with a base station (130) associated with the modular sensor core and/or a mobile sensor platform (110) and the sensor assembly is configured to provide analyte sensor data as the modular sensor core is maneuvered within a survey area.

Abstract: Various techniques are provided to implement a desorber of a sensor detector device that permits manual operation and is completely detachable from a main body of the sensor detector device. In one example, a device includes a desorber. The desorber includes an inlet comprising a fluid path configured to receive samples vaporized from sample media. The desorber also includes a cap configured to slide toward the inlet in response to a manual actuation of the cap performed by a user to transition the desorber from an open position to a closed position. The desorber further includes a heater configured to slide with the cap toward the inlet in response to the user actuation and vaporize the samples while the desorber is in the closed position.

Abstract: A skateboard wheel system for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels. The skateboard wheel system includes a rim member, manufactured in a plurality of designs and appearances, with a bearing pressed into both a first end and a second end and wheel member pressed about the rim member retained by a ring member. The rim member is comprised of an aperture for mounting the skateboard wheel system to the truck of the skateboard, a flange element located towards the first end for retaining the wheel member and a first threads towards the second end for retaining the ring member. The wheel member has a rib integrated to an interior surface for retaining it to the rim member. The ring member includes a plurality of tool apertures to be utilized while assembling the ring member to the rim member.
