Led-based illumination module attachment to a light fixture

Abstract: A mounting collar on a light fixture provides a compressive force between the illumination module and a light fixture. For example, a mounting collar that is fixed to the light fixture may engage with an illumination module to deform elastic mounting members on the illumination module to generate the compressive force. The mounting collar may include tapered features on first and second members that are moveable with respect to each other and that when engaged generate the compressive force. The mounting collar may include elastic mounting members on first and second members that move with respect to each other, wherein the movement deforms the elastic mounting members to generate the compressive force. The mounting collar may include an elastic member, wherein movement movement of the mounting collar relative to a light fixture deforms the elastic member to generate the compressive force.

Cervical Collars are Insufficient for Immobilizing an Unstable Cervical Spine Injury

Abstract: Background Cervical orthoses are commonly used for extrication, transportation, and definitive immobilization for cervical trauma patients. Various designs have been tested frequently in young, healthy individuals. To date, no one has reported the effectiveness of collar immobilization in the presence of an unstable mid-cervical spine. Study Objectives To determine the extent to which cervical orthoses immobilize the cervical spine in a cadaveric model with and without a spinal instability. Methods This study used a repeated-measures design to quantify motion on multiple axes. Five lightly embalmed cadavers with no history of cervical pathology were used. An electromagnetic motion-tracking system captured segmental motion at C5–C6 while the spine was maneuvered through the range of motion in each plane. Testing was carried out in intact conditions after a global instability was created at C5–C6. Three collar conditions were tested: a one-piece extraction collar (Ambu Inc., Linthicum, MD), a two-piece collar (Aspen Sierra, Aspen Medical Products, Irvine, CA), and no collar. Gardner-Wells tongs were affixed to the skull and used to apply motion in flexion-extension, lateral bending, and rotation. Statistical analysis was carried out to evaluate the conditions: collar use by instability (3 × 2). Results Neither the one- nor the two-piece collar was effective at significantly reducing segmental motion in the stable or unstable condition. There was dramatically more motion in the unstable state, as would be expected. Conclusion Although using a cervical collar is better than no immobilization, collars do not effectively reduce motion in an unstable cervical spine cadaver model. Further study is needed to develop other immobilization techniques that will adequately immobilize an injured, unstable cervical spine.

In response to receiving a third user action, the current location of the object is finalized on the rendered display and the collar is removed from around the object on the rendered display.

Effects of a cooling collar on affect, ratings of perceived exertion, and running performance in the heat

Abstract: During prolonged exercise, ratings of perceived exertion (RPE) and affect (pleasure; activation) play an important role in performance, especially in hot conditions. Although various mechanisms have been tried to manage the effects of heat (e.g. cooling jackets), the purpose of the current research was to assess the effect of a cooling collar on RPE, affect, thermal sensation, and running performance in the heat. Participants (n =8) wore a cold collar, uncooled collar or no collar as they completed three 90-min preloaded treadmill time-trials in the heat (30.5±0.1°C), which included 75 min at ∼60% [Vdot]O2max followed by a 15-min time-trial. Affect, RPE, and thermal sensation were measured throughout. Performance during the time-trial was significantly improved in the cold collar compared with the uncooled collar and no-collar trials; however, pleasure and activation ratings were highest for the no-collar trial. Findings suggest that a cooling collar may improve performance, but not necessarily “...
