    摘要: A hairspray composition is described that includes a nonionic polymer and an anionic polymer. The nonionic polymer is formed from monomers having at least one unneutralized carboxylic acid. The anionic polymer is identical to the nonionic one, except that all of the carboxylic acid groups are in salt form. Advantageously, the composition further includes an acrylic resin, most especially an amphoteric one. Best results are achieved when the acrylic resin is neutralized with a relatively small cation such as potassium and a second cation of a water soluble fatty amine. These compositions employ water as the carrier and dimethyl ether as propellant.

    摘要: The majority of applications for head mounted display (HMD) users, irrespective of whether they are for short-term, long-term, low vision, augmented reality, etc. yield a conflicting set of tradeoffs between user comfort and minimal fatigue and strain during use, ease of attachment, minimizing intrusiveness and aesthetics which must be concurrently balanced with and are often in conflict with providing an optical vision system that provides the user with a wide field of view and high image resolution whilst also offering a large exit pupil for eye placement with sufficient eye clearance. Further, individual users' needs vary as do their needs with the general task at-hand, visual focus, and various regions-of-interest within their field of view. To address these issues, it is necessary to provide a high performance optical system, eyepiece design, and system features which overcome these limitations.

    摘要: For users exploiting near-to-eye (NR2I) displays for augmented reality and/or correction of low vision then the user is typically going to wear the immersive or non-immersive NR2I displays for specific tasks, for specific visual environments, etc. and hence there is an issue of repeatedly attaching and removing the NR2I display. Further, in the majority of applications irrespective of whether for short-term, long-term, low vision, augmented reality, etc. there is a conflicting tradeoff between user comfort, ease of attachment, minimizing intrusiveness and aesthetics. Accordingly, a means of pivotably attaching and supporting a NR2I display is provided wherein the pivotable mounts may be permanently attached, attached, or demountably attached to a frame which may include for some user's prescription lenses.

    摘要: A ship navigation and handling training simulator comprises a console for use by an instructor and a console for use by a student navigator. Each console has a visual display unit with a screen to provide a mimic display of the ship and environmental information, and the instructor console is associated with two groups of controls for setting in, respectively, the environmental and display information applicable to the navigational or ship handling exercise to be performed and information representing ship/tug control decisions by the student. The consoles are interconnected by a voice link so that the instructor can initially set the environmental and display controls and subsequently adjust the group of controls for ship/tug control in accordance with vocal instructions from the student transmitted via the voice link. Computer means are programmed to control the displays on the screens on a time scale in accordance with the information set-in on both groups of controls and the changes thereto during the course of the exercise.
