Abstract: A litter lift system includes a winch and a lifting strap. The winch includes a rotatable spool. The lifting strap has one end coupled to the rotatable spool and is movable due to rotation of the rotatable spool. The lifting strap has a first lifting segment and a second lifting segment positioned away from the end of the lifting strap coupled to the rotatable spool. The first lifting segment and the second lifting segment are each forked to interface with a frame of a litter at first lifting segment and second lifting segment distal ends, wherein a coupling is attached to the first lifting segment. Rotation of the rotatable spool in a first direction raises the first lifting segment and the second lifting segment. Rotation of the rotatable spool in a second direction different from the first direction lowers the first lifting segment and the second lifting segment.

Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, and an LED lighting system coupled to a light transmissive illumination system of the optical assembly. An optical imperfection of the illumination system directs light from the LED lighting system to uniformly irradiate a reflective image display to produce an image that is reflected through the illumination system to provide the displayed content to the user.

Abstract: An eyepiece includes a mechanical frame adapted to secure a lens and an image source facility above the lens. The image source facility includes an LED, a planar illumination facility and a reflective display. The planar illumination facility converts a light beam from the LED received on a side of the planar illumination facility into a top emitting planar light source, uniformly illuminates the reflective display, and is substantially transmissive to allow reflected light to pass through towards a beam splitter. The beam splitter is positioned to receive the image light and to reflect a portion onto a mirrored surface. The mirrored surface is positioned and shaped to reflect the image light into an eye of a user of the eyepiece thereby providing an image within a field of view, the mirrored surface further adapted to be partially transmissive within an area of image reflectance.

Abstract: This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content. The optical assembly includes a light transmissive wedge-shaped illumination system with angle selective coatings and an LED lighting system coupled to an edge of the wedge. An angled surface of the wedge directs light from the LED lighting system to uniformly irradiate a reflective image display to produce an image that is reflected through the illumination system to provide the displayed content to the user.

Abstract: A system and method for detecting and storing mobile device usage by a driver of a vehicle. An antenna in a vehicle is configured and positioned to detect mobile device signals from the driver area in the vehicle. A processor in communication with the antenna analyzes the detected signals for frequency and strength. The antenna and processor may communicate with vehicle data collection systems (e.g., GPS, telemetry, etc.) such that the mobile device usage data may be collected along with the vehicle operation data. The mobile device usage data and vehicle operational data can be evaluated to determine the impact of mobile device usage by the driver of a vehicle. The data may be especially useful to the trucking, train, bus, and mass transit industries in order to educate drivers about the dangers associated with using mobile devices while driving.

Abstract: In one embodiment, a ferroelectric material is processed by placing the material in an environment including metal vapor and heating the material to a temperature below the Curie temperature of the material. This allows the bulk conductivity of the ferroelectric material to be increased without substantially degrading its ferroelectric domain properties. In one embodiment, the ferroelectric material comprises lithium tantalate and the metal vapor comprises zinc.

Abstract: One embodiment disclosed relates to a method for sealing an active area of a non-silicon-based device on a wafer. The method includes providing a sacrificial material over at least the active area of the non-silicon-based device, depositing a seal coating over the wafer so that the seal coating covers the sacrificial material, and replacing the sacrificial material with a target atmosphere. Another embodiment disclosed relates to a non-silicon-based device sealed at the wafer level (i.e. prior to separation of the die from the wafer). The device includes an active area to be protected, a contact area, and a lithographically-formed structure sealing at least the active area and leaving at least a portion of the contact area exposed.
