A basketball game includes at least one ball, a playing surface, a support structure, a backboard, a hoop, and a plurality of spot locations, and may further include a timekeeping device. Each spot location has a first surface with a first marking thereon and a second surface, in opposition to the first surface, with a second marking thereon. On at least one spot location, the first marking differs from the second marking. The different markings and the mobility of the spot locations relative to one another allow for a greater number of different, creative sets of rules using fewer spot locations.

Abstract: Signature circuits are used during testing of an integrated circuit. Test vectors are applied as inputs to a circuit under test. A signature circuit stores a “signature” for the circuit under test based on a combination of signals from the circuit under test in response to test vectors and a previous stored state of the signature register. The value contained in the signature register at the end of the test is the signature. A fault-free circuit generates a particular signature for the applied test vectors. Faults can be determined by detecting variances from the expected signature. In one embodiment, the signature circuit uses a combination of two error detection codes.

Specifically, the translation system comprises a web-based translator adapted to receive a text input and transmit a translated output, and a code bridge adapted to provide a data interconnection between the translator and a content source, wherein the code bridge extracts the text input from the content source, connects to the translator, and transmits the translated output to the content source.

Abstract: The present invention provides a circuit for detecting and correcting errors in a bit stream. At least two logic gates receive inputs from a plurality of circuit elements. The plurality of circuit elements are coupled to receive and store a portion of a bit stream. At the end of a CRC error detection division operation, each circuit element corresponds to a bit in a bit error pattern syndrome and the logic gates determine if the contents of the circuit elements match specific bit error patterns. The circuit causes the state of at least one bit in the bit stream to change if the contents of the plurality of circuit elements match one of the specific bit patterns. The circuit is advantageous in that it may detect single bit errors, and double bit errors that may be caused by error duplication characteristic of a scrambler.
