Abstract: A method of manufacturing a display includes coupling light from at least one light source into a front illumination film-based lightguide comprising a pressure sensitive adhesive layer between a core polymer film layer and a diffusely reflective release liner such that light from the at least one light source propagates by total internal reflection through the core polymer film layer, is extracted from the core polymer film layer, passes through the pressure sensitive adhesive layer, diffusely reflects from the diffusely reflective release liner and passes back through the pressure sensitive adhesive layer and core polymer film layer out of the front illumination film-based lightguide; analyzing the light exiting front illumination film-based lightguide from the at least one light source for defects; removing the diffusely reflective release liner from the front illumination film-based lightguide after analyzing; and laminating the front illumination film-based lightguide to a reflective spatial light modula

Abstract: A display includes a reflective spatial light modulator, an angularly varying diffusion film that that transmits and scatters light incident within a first angular range and transmits light un-deviated incident within a second angular range outside of the first angular range, and a frontlight including a light source positioned to emit light into a film with a light emitting region positioned between the reflective spatial light modulator and the varying angle diffusion film. In one embodiment light extracted in the light emitting region is incident on a spatial light modulating layer at an angle of peak luminous intensity less than 30 degrees in a second layer from the surface normal of the spatial light modulating layer, reflects from the reflective spatial light modulator, passes through the film, is scattered by the angularly varying diffusion film, and exits the display.

Abstract: Nail care systems in accordance with embodiments of the present invention can include a housing and a nail clipper associated with the housing, the nail clipper having an upper member and a lower member banded by an upper lever and a lower lever. Cutting blades associated with the members can be pinched together by actuating the levers. A container formed between the members can receive nail clippings ejected away from the nail. A nail filer associated with the housing includes a rotatable file that can be used to file nails. This description is not intended to be a complete description of, or limit the scope of, the invention.

Abstract: The invention covers a robot cleaner that includes a cleaning unit and wheels to move the robot cleaner. The robot cleaner also includes a processor for controlling cleaning that is capable of estimating the size of a room based on distances between obstacles. The robot cleaner has several modes of operation that allow it to clean an entire room more effectively.

Abstract: The invention pertains to a robot cleaning system that includes a robotic cleaner having a tactile sensor and a barrier unit, wherein the barrier unit is such that the tactile sensor on the robot cleaner is triggered by contact with the barrier unit. As a result the robot changes directions. The barrier unit can be adapted to avoid sliding, such as when the robot comes into contact with it. The anti-slide element can be projections such as hooks or rubber grommets and the like.

Abstract: A method includes receiving input from a user and, in response to the input, selecting one of a BCV (boot connection vector) pointer and a BEV (bootstrap entry vector) pointer to have a non-null value.

Abstract: A tower top amplifier for use outdoors in a radio frequency communications system has a surge suppression device for suppressing electrical surges caused by lightning strikes. The surge suppression circuit has a short circuit inductive coupling loop connected to a coaxial cable connector. By using a capacitor connected in parallel with an inductive probe, the surge suppression circuit operates as an open circuit at the operating frequency of the system. In addition, at the operating frequency, the resistor matches the impedance of the system connected to the coaxial cable connector. But in the event of a lightning strike or other electrical event, the inductive coupling loop short circuits the surge current to ground, thereby protecting the amplifier system from damage.
