Abstract: Ion mobility spectrometry (IMS) systems, devices, and associated methods of operation are disclosed herein. In one embodiment, an IMS system includes an ionization region configured to receive and ionize a sample into ionized molecules and a detector configured to detect ionized molecules. The IMS system also includes a drift region in between and directly coupled to both the ionization region and the detector. The drift tube includes a first ion gate proximate the ionization region and a second ion gate proximate the detector. The first and second ion gates are configured to alternately introduce a batch of ionized molecules toward the detector while the other is maintained open, thereby allowing accurate measurement of a drift time of the ionized molecules corresponding to a drift length that is a distance between the first and second ion gates.

Abstract: A limb supporting apparatus adaptable for use during orthopedic surgery on a patient's limb having a platform base; an appendage rest supported by the platform base and adapted to immobilize the limb; an access port supported by the platform base; and a curved cannula supported by the access port and adapted to facilitate access to target bone during orthopedic surgery. Another aspect of the invention provides a method of performing an orthopedic procedure on a limb including the steps of immobilizing the limb on an appendage rest of a platform base; aligning a curved cannula supported by an access port with a target bone of the limb; and performing an orthopedic procedure on the target bone through the cannula.

Abstract: A single selection valve allows the selection of three or more alternate flow routes without any unswept volume along any of the routes. The selection valve has a rotor (22) that can pivot about an axis (30) on a stator (12), the stator having ports (1-8) generally lying on a port circle (54) that is centered on the axis and the rotor having channels (60, 62) on its front face that faces the rear of the stator. Each rotor channel has a radial groove (70) with a port end (72) lying on the port circle, and each channel has an arc groove (74) that connects to the radial groove and that extends substantially circumferentially along an arc circle (76) that is centered on the axis, but that has a smaller radius than the radius of the port circle.
