Abstract: A hidden image game piece (1) and a method by which a hidden image game piec e is produced. A first pattern of colored ink (30) is deposited on a transpare nt or highly translucent substrate at 110180 density, forming the image which i s to be hidden. Then a second pattern of colored ink (20), of a different colo r than the first pattern's ink, is deposited upon the substrate on top of the first pattern, at 90170 density. When the game piece is flooded with additiv e light of the same color as the second pattern's ink, the previously conceale d image, composed of the pattern's ink, becomes perceptible. Because a transparent of highly translucent substrate is used for the game piece, and because the density of the ink application is controlled within specific ranges, this game piece is used with a computer monitor, or with other low- intensity sources of additive light.

Abstract: A system for redistributing a multiple input audio/video and data signals having a redistributing device equipped to receive signals in a multiple formats and redistribute a selected signal to a user's premises over conductors, preferably existing twisted-pair telephone wire. The redistributing device is in interactive communication with a communications interface located in the user's premises which receives user-input control signals and contains switching circuitry which routes the selected signal to the user's premises where it is received by the receiving unit such as a television receiver. A single redistributing device services an entire multi-user network from a common distribution point, and services multiple users independently. The system of the invention does not interfere with normal use of the telephone network, so users can interactively access services provided by the system and use the telephone at the same time. In one preferred embodiment the system of the invention dynamically allocates frequencies and modulation techniques to various output signals, to maximize spectral efficiency and minimize interference and cross-talk.

Patent CA-2423621-A1 (CA)
Inventor: PADHYE JITENDRA D
IPC: H04H20/00
Filed: 2003-03-28
Abstract: A method and system for optimizing channel access scheduling for multiple wireless computing devices over a wireless network improves channel access efficiency with respect to a primary channel. An access point, or host computer, includes a host transceiver for receiving control information from the wireless computing devices over a low power channel. Upon receiving the control information, the access point applies a scheduling algorithm to schedule channel access for the wireless computing devices to transmit data over the primary communication channel. The wireless computing devices include a low power radio for receiving scheduling information via the low power channel during idle periods. When the scheduling information is received, the wireless computing device activates its primary channel network interface components to communicate data through the primary channel. When the computing device is idle, the device is configured to power down all of its components with the exception of the circuitry required to power the low power channel. As such, the low power channel is maintained in an active state for receiving scheduling information, such as an access schedule, during both idle and non-idle periods.

Title: Method, system, and apparatus for converting numbers between measurement systems based upon semantically labeled strings
Inventor: MOORE THOMAS G
IPC: G06F17/22
Filed: 2003-05-05
Abstract: A method, system, and apparatus are provided for converting numbers between different units of measurement. When a string of text is entered into an application program, the string is analyzed to determine whether the string of text includes a number having an associated unit name. If the string of text includes a number having an associated unit name, the number is semantically labeled with schema information that identifies the unit name as a source unit of measurement. When a selection is received of the number or an indication that the number is labeled with schema information, a list of actions may be provided identifying conversion options available for the number. One of the conversion options may then be selected resulting in the conversion of the selected number to the destination unit of measure identified by the selected action. The converted number may then be inserted into the string of text to replace the selected number along with a unit name corresponding to the destination unit of measure.
