Abstract: A head mounted display device includes a light source that emits a high coherence light beam, a beam expansion/diverging element that expands the light beam emitted by the light source, and a beam converging element that converges the expanded light beam into a viewing zone. The light beam from the beam converging element is incident onto a spatial light modulator (SLM), and the SLM is configured to add a phase pattern and/or an amplitude pattern to the light beam to generate a virtual image that is visible to a user wearing the head mounted display device. The light converging element creates a beam or scanning beam axis that converges towards the eye, which enables a large field of view for a virtual or holographic image to be displayed.

Abstract: A test strip device exhibits visual changes, such as color changes, when there is a only slight difference in the composition of liquids such as gasoline, oil, ethanol and water. Such a slight liquid composition difference usually requires a sophisticated and expensive instrument to differentiate. The test strip consists of one and more than one inverse opal films deposited on a substrate and achieves this goal of differentiation in a simple, fast and energy-free manner.

Abstract: A head-up-display (HUD) system includes at least one scanning laser projector operative to generate laser light, and a stacked array of multiple-switchable screens arranged relative to the projector to receive laser light generated by the projector, each screen of the stacked array of multiple-switchable screens spaced apart from one another and operative to switch between a transparent state and a diffusive state. A controller is operatively coupled to the stacked array of multiple-switchable screens, the controller configured to time sequentially switch each screen of the array from a transparent state to a diffusive state, wherein only one screen is switched to the diffusive state at any given time. An output of the projector is arranged at an angle or a distance from imaging optics succeeding the array of screens to prevent a specular beam emitted by the at least one scanning laser projector from intercepting the imaging optics succeeding the array of screens when all screens are in the transparent state.

Abstract: A wearable device includes a light source and a display unit. The display unit includes an image engine that controls the light source to generate image content for display, and a plurality of optical elements that direct the image content into a viewing zone. An eye monitor measures information pertaining to an eye configuration of a user wearing the wearable device, and the image content is visible to the user when the eye is aligned with respect to the viewing zone. A spatial light modulator (SLM) moves a position of the viewing zone based on the eye configuration information measured by the eye monitor. The eye monitor measures pupil size of the user, and the optical elements direct the image content into the viewing zone that is smaller in at least one dimension than twice the measured pupil size. The light source may include a micro-electro-mechanical systems (MEMS) scanning mirror.

Abstract: A head mounted display device includes a switchable light source that is switched to emit light for generating at least one viewing zone, and a panel illumination unit illuminated by the light source. The panel illumination unit converges the light onto an image panel that selectively transmits light at different pixels to generate image content. An eye monitor measures information pertaining to an eye configuration of a user, and the image content is visible to the user when the eye is aligned with respect to the viewing zone. The panel illumination unit converges the light such that light emitted by the image panel converges into the viewing zone positioned based on the eye configuration information measured by the eye monitor, with limited divergence such that when the display device is worn by the user, the image panel is located at a distance from the user's eye closer than a distance where the eye can focus the pixels.

Abstract: A method for reducing paging traffic between a gateway (GW) and plural base stations (BSs) is provided when paging user equipments (UEs). A cache map, which records most-recently visited BSs of selected UEs, is used to limit the number of BSs in the paging of each selected UE, thereby reducing paging traffic. Furthermore, paging requests sent to the same BS node are grouped into one batch in generating a transport-layer payload, reducing the number of generated transport-layer messages. When used in a LTE system, piggybacking paging requests as provided by the SCTP reduces paging traffic and windowing/congestion control overhead at the transport layer. Transmission efficiency is thus improved. In addition, the number of paging requests sent out by the GW node per one paging interval is controlled to be not greater than a pre-determined maximum value to further limit paging traffic for avoiding occurrence of a paging storm.

Abstract: A method of treating a patient to improve liver functioning includes providing a drug composed of at least one of pharmaceutical 2-(4-morpholinoaniline)-6-cyclohexyl aminopurine and a salt thereof; and administering the drug to the patient in a manner and dosage effective to improve liver functioning. The 2-(4-morpholinoaniline)-6-cyclohexyl aminopurine can inhibit the activated hepatic stellate cells from synthesizing and expressing collagens and other extracellular matrix proteins including MMPs and TIMPs, and so it can inhibit liver fibrosis. In the liver, it can inhibit collagen synthesis and expression, and therefore reverse and treat hepatitis and liver cirrhosis effectively.
