A puzzle including multiple puzzle pieces, each including a two-dimensional outline forming a surface covering area, that are arrangeable to cover a puzzle base. One set of puzzle pieces includes fourteen total pieces with eleven of the pieces having distinct outlines corresponding to the eleven different ways the six faces of a unit cube can be unfolded while remaining connected together and then flattened. The two-dimensional outlines of the other three pieces can be arranged to form the outli...

A video system is disclosed which is capable of receiving digital data from a source such as a video camera, and subsequently transferring the received data into a main frame buffer for display on a video display, where the data from the source can overlay a primary image stored in the main frame buffer. An auxiliary frame buffer, consisting of a bank of dual-port RAMs, receives the data of the overlay image via its serial port and transfers this data into the randomly accessible array therein. ...

A method of overlaying sulphur concrete is adapted for use in placing sulphur concrete against or over an existing solid surface such as the exterior surface of a wall, floor, or column base. The existing surface, which typically is a portland cement concrete surface, is prepared by first applying a layer of a bituminous material containing a bitumen which liquifies at temperatures corresponding to the pour temperatures of the sulphur concrete. The sulphur concrete is poured against or over the ...

A video overlay circuit (110) overlays a first video signal (COMPVID) with a second video signal (LUM2, CHROM2). The first video signal is partitioned by filtering out a first chrominance component (CHROM1) which is subtracted from the first video signal to produce a first luminance component (LUM1). A fast switch (5) switches between the first luminance component and a second luminance component (LUM2) of the second video signal over a transition period of clock cycles to produce an overlaid lu...

A selective call two-way communication system having a plurality of selective call transceiver units (170) using an inbound channel overlay on an outbound selective call system, the selective call transceiver units comprising a receiver (173) for receiving a message having an address directed to and decodable by the receiver wherein the address (58) points to a vector (60) , a decoder (174) for decoding a pointer within the vector that points to a control information portion (66) within an outbo...

A replica of fossil or the like can be handily manufactured using color prints obtained by photographing the fossil without preparing a mother mold. An overlaying replica is manufactured by preparing a plurality of prints, each having the same size, and obtained by photographing a collected specimen from given angles, cutting specimen parts to form a plurality of specimen prints, bonding said specimen prints by a solid paste one by one substantially in the same direction while they are overlaid ...

A spread-spectrum satellite system for communicating data and paging messages to a plurality of remote units. The spread-spectrum communications system has a satellite with an antenna beamwidth located within a same geographical region as covered by an existing FDMA, TDMA or other mobile-satellite system. The spread-spectrum satellite system has a device for converting the format of the data into a form suitable for communicating over radio waves, a spread-spectrum modulator for spread-spectrum ...

A multicolor half-tone image of an original object is formed on preformed plastic containers or other recipient surface by printing such image while wet from an offset blanket cylinder on which the image is formed by overlying a plurality of one-color half-tone images.

The overlaying of video image data from an external source, such as a video camera, onto a representation of display data becomes accomplished by using a serial port of an auxiliary frame buffer to receive the serial data from the external source. The source data then becomes transferred from serial registers included within the auxiliary frame buffer into the randomly accessible array of the auxiliary frame buffer. Subsequent execution of a DMA (Direct Memory Access) places the source data over...

An image processing apparatus with an image overlaying mechanism by which image data from an inputting means source are overlaid with image data stored in a memory. A control unit controls reading out image data from the memory and storing overlaid image data into the memory effectively in parallel with the reading operation, and in the storing, stores overlaid image data being stored at addresses of the memory at which read out image data were stored. An output unit outputs overlaid image from ...
