摘要： The invention relates to a keystone correction system and method. The system includes a projector for projecting an image on a projection surface and a platform to allow a user to vertically rotate the projector before horizontally rotating the projector. The projector corrects for keystone distortion responsive to the projector's vertical and horizontal position. The platform increases the keystone range of the projector. The keystone correction method includes moving a projector in a vertical direction and moving a projector in a horizontal direction after moving the projector in a vertical direction.

摘要： An accessory for use with a bed or cot having a frame is described. The accessory has a first upright member joined to a first corner of the frame, a second upright member joined to a second corner of the frame, and a variable length cross member connected to the first and second upright members to form a stable, substantially U-shaped structure therewith. Each of the upright members is also connected to a respective leg member of the bed or cot to provide improved stability for the accessory. Further, each upright member has a plurality of hooks for allowing a user to hang clothes, equipment, and other personal items. The cross member is provided with apertures at its ends for receiving the tip portions of the upright members and for allowing the tip portions to extend above the cross member. By allowing the tips of the upright members to extend above the cross member so that a user is able to put slidable devices for holding objects, such as a clothes hanger, on the cross member and not have them slide off the ends of the cross member.

摘要： Using a GaN growth furnace, at least three different techniques can be used for forming the targets for the deposition of thin films. In the first, nitrides can be deposited as a dense coating on a target backing plate for use as a target. In this approach, the backing plate is placed near the Group III metal. During processing, the Group III metal or metal halide vaporizes and reacts with the nitrogen source to deposit a dense polycrystalline layer on the backing plate. To build up a thick layer on the backing plate, the backing plate is repeatedly placed in the processing furnace until a satisfactory thickness is attained. For the second approach, a properly shaped reaction vessel, the dense, thick Group III nitride crust that forms on top of the Group III metal during the process can be used directly or mechanically altered to meet the size requirements for a sputtering target holder. As a third approach, the Group III nitride material can be ground into a fine powder using traditional ceramic powder processing methods and then pressed to consolidate the powder into a sputtering target. The third processing option would typically lead to a low density target; however, this "green" compact can then be reinserted into the same processing apparatus that the original powder was synthesized to infiltrate the open pores with the same or another group III metal nitride. This would produce a high density, thick target.

摘要： Lamp dimmers are disclosed in which, in the course of varying average power supplied to the lamp load, the semiconductor power control devices transition between one and the other of substantially conductive and non-conductive power conditions, the duration of the transition by the power control devices themselves is increased beyond the minimum possible duration to reduce generated EMI. The dimmers disclosed provide for varying the direction, duration, shape, and phase angle of transitions.

摘要： A universal handle for household and other hand-held implements, the handle being adapted to ergonomically render the implement to which it is applied useable by individuals who have diffculty in firmly grasping a conventional handle. The universal handle, which is fabricated of elastomeric material having good thermal insulation and cushioning properties, includes an internal cavity to socket the core shank of the implement. The handle has an elliptical cross section, the opposing sides of the handle adjacent its upper end each having a concave depression, in each of which an array of spaced, flexible fins is anchored to define a depressible grip site. When the fingers of a user's hand are clenched about the handle, the internal region of the resultant fist conforms to the form of the handle to provide a good grip thereon, the thumb and forefinger pressing into the grip sites to enhance the user's grip on the handle.

摘要： A light projector, suitable for entertainment lighting and comprising a light source and associated light collecting means producing an elongated beam having an optical centerline that is preferably substantially horizontal, is provided with a means, typically a mirror, mounted to a first support adapted for rotation about an axis coincident with that centerline, for redirecting the beam through a first plane perpendicular to that substantially horizontal axis and centerline. A second mirror is rotatably mounted to the first support so that the redirected beam falls upon it, redirecting the beam a second time, through a second plane perpendicular to the centerline of the beam in the region between the first and second mirrors; a second plane that is also substantially parallel to the axis of rotation of the first support. The first support is supported for rotation about said axis on both sides of the means for redirecting.
