A backlight apparatus has a collimating waveguide with a light input end, a top surface, a bottom surface, opposing sides, a far end opposite the light input end, and a total internal reflection critical angle for the material of the waveguide. A plurality of first facets are formed in the bottom surface distributed along the waveguide between the light input end and the far end. Each of the first facets has a first facet bottom surface which converges toward the top surface in a direction away from the far end relative to the top surface. A light scattering and reflective surface is disposed adjacent the far end of the collimating waveguide. The first facet bottom surfaces cause light rays entering the light input end to be totally internally reflected to the far end of the collimating waveguide wherein the scattering and reflective surface at the far end reflects and scatters light rays incident thereon back toward the light input end. The first facet bottom surfaces then cause the light rays reflected from the far end to exit the top surface. The first facet bottom surfaces may be formed either as straight facets or as curved surface facets and may also be alternatively formed having a reflective material layer thereon.

A method of playing a virtual or virtual/mechanical multireel slot game. A grid of at least 3 rows×3 columns, but preferably 3 rows×5 columns, is presented on a screen, with a second, opaque blanketing layer of color or graphics over the grid, so as to hide symbols on the reels below. After the wager, reels on the bottom layer spin (or are virtually and randomly positioned in any manner), hidden from the player by the blanketing layer. An “erasing” indicium then glides from outside the grid (preferably across the top row of 5 reels, from left to right), over the blanketing layer, erasing the color layer to expose the symbols on the reels below. The indicium preferably (or always) moves in one direction only until it hits the end of a row, the top or bottom of a column, or a revealed symbol that alters movement of the indicium. When the indicium encounters this situation, it may hesitate for a moment, then randomly pick a direction in which to continue. It may continue in the same direction or turn 90° clockwise or 90° counterclockwise. It may even move diagonally. If the indicium turns and continues over the reels, more symbols are revealed until the indicium again reaches a turning point. Payouts are awarded according to a predetermined paytable for single special symbols and/or for sets such as multiple same symbols shown, whether the symbols are contiguous or not.

This invention provides a foldable/retractable and unfoldable/deployable, rearwardly tapered aerodynamic assembly for use on the rear trailer bodies and other vehicles that accommodate dual swing-out doors. The aerodynamic assembly includes a right half mounted on the right hand door and a left half mounted on a left hand door. Each half is constructed with a side panel, top panel and bottom panel, which each form half of an overall tapered box when deployed on the rear of the vehicle, the bottom panels and top panels being sealed together at a pair of overlapping weather seals along the centerline. The panels are relatively thin, but durable, and are joined to each other by resilient strip hinges. The top and bottom panels are also hinged to form two sections along diagonal lines to facilitate folding of all panels in a relatively low-profile stacked orientation. This low profile allows the doors to be swung through approximately 270 degrees to be secured to the sides of the body in a manner that does not interfere with adjacent doors or bodies in, for example a multi-bay loading dock. A swing arm assembly and gas spring biases the panels into a deployed position that can be refolded by grasping the side panel and rotating it inward toward the door surface. The top and bottom panels are partly inwardly folded when deployed to define external valleys using a stop assembly. This ensures that the panels fold readily when desired without the two sections of the panels “locking up”.

Each key may be also defined by a unique region of numeric values or a unique region of color pixels allowing ease in changing keyboard location, size and orientation.

An ultrasonic imaging array has two independent, interleaved linear subarrays occupying a common array face. The subarrays are independently steerable and focusable in different imaging planes. The subelements making up the elements in of the subarrays is preferably quadrilateral. Adjacent subelements in each element are electrically connected via an interconnect portion such that the interconnect portion connecting each pair of adjacent subelements in each element is substantially linear and is aligned with the diagonals of the adjacent subelements. A preferred acoustic lens is curved in both azimuth and elevation directions, whereby the subarrays are independently focusable. By transmitting in one plane and simultaneously receiving in a different, orthogonal plane, a system including the array can image a 3-D region of interest (ROI). In a volumetric embodiment of the invention two orthogonal B-mode images of a structure within the ROI are displayed simultaneously. The user may then trace the outlines of the images and the system therefrom calculates the volume of the structure.

A technique efficiently corrects multiple storage device failures in a storage array using a combination of a single diagonal parity group and multiple row parity groups. The storage array includes a plurality of concatenated sub-arrays, wherein each sub-array includes a set of data storage devices and a parity storage device. Each row parity group is associated with a sub-array of the array. The array further includes a global parity storage device holding diagonal parity computed across the concatenation of the sub-arrays. Instead of requiring that each parity group contain both a row parity device and a diagonal parity device, the array is composed of a collection of row parity groups. Diagonal parity is calculated across the full array.

An elongate medical device includes a sensor configured to detect one or more characteristics of an electromagnetic field in which the device is disposed. The sensor includes an electrically-insulative substrate, rectangular in shape, and a patterned, conductive trace disposed on the substrate. The patterned trace includes a plurality of diagonal sections parallel to one another, arranged with a relatively low pitch. The substrate is wrapped into a cylindrical shape thereby forming a three-dimensional spiral capable of functioning as a micro-electromagnetic sensor. A medical positioning system is responsive to the signal from the sensor to determine a position and/or orientation of the sensor.

This invention relates generally to a packet recovery algorithm for real-time (live) multi-media communication over packet-switched networks, such as the Internet. Such multi-media communication includes video, audio, data or any combination thereof. More specifically, the invention comprises a forward error correction (FEC) algorithm that addresses both random and burst packet loss and errors, and that can be adjusted to tradeoff the recoverability of missing packets and the latency incurred. The transmitter calculates parity packets for the rows, columns and diagonals of a block of multi-media data packets using the exclusive or (XOR) operation and communicates the parity packets along with the multi-media data packets to the receiver. The receiver uses the parity packets to recover missing multi-media data packets in the block. The FEC algorithm is designed to be able to recover long bursts of consecutive missing data packets. If some parity packets are missing, they too can be recovered using an extra single parity packet, so that they can be used to recover other missing data packets. The invention applies to both one-way real-time streaming applications and two-way real-time interactive applications, and to both wired and wireless networks. The invention retains backwards compatibility with existing standards governing FEC for professional video over IP networks.

The invention provides a method and apparatus for identifying gestures performed by a user to control an interactive display. The gestures are identified based on a bounding box enclosing the points at which a user contacts a touch sensor corresponding with the display surface. The invention thus permits the use of inexpensive and highly reliable grid-based touch sensors that provide a bounding box to describe contact information. In identifying the gestures, the position, motion, shape, and deformation of the bounding box may all be considered. In particular, the center, width, height, aspect ratio, length of the diagonal, and orientation of the diagonal of the bounding box may be determined. A stretch factor, defined as the maximum of the ratio of the height of the bounding box to the width of the bounding box and the ratio of the width of the bounding box to the height of the bounding box, may also be computed. Finally, gestures may be identified based on the changes in time of these characteristics and quantities.
