Title: School bus safety device
Inventor: FJORDBOTTEN PAUL
IPC: B60Q9/00
Filed: 2000-07-18
Abstract: A school bus safety device provides an engine status line wired to a voltage  detection location. The voltage detection location is a point in the electrical system of the school bus which is typically at a high voltage potential when the engine is in operation, and is at the same potential as ground when the engine is turned off. An edge-triggered logic device, such as a flip-flop, receives the engine status line as a clock pulse input. In a typical application, the falling edge of the engine status line causes the output line of the logic device to go high, thereby driving an annunciator, such as  a buzzer. Therefore, turning off the engine of the bus causes the buzzer to sound. The driver walks to th e rear of the bus and notices if any sleeping children are left on board. A key switch device, located in the back of the bus, is used to send a reset to the logic device, thereby turning off the buzzer. The driver  then walks back to the front of the bus, double-checking to see that all children are off the bus.</SDOAB >

Patent CA-2335003-A1 (CA)
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Title: Dynamic bit allocation for statistical multiplexing of compressed and uncompressed digital video signals
Inventor: LUTHRA AJAY
IPC: H04N21/434
Filed: 1999-07-22
Abstract: The present invention relates to a method and apparatus for allocating bits in a statistical multiplexing system (stat mux). A statistical multiplexer (stat mux) (600) accommodates both compressed and uncompressed video programs using transcoding (640, 650) and encoding (620, 630), respectively. Hierarchical dynamic bit allocation is used, starting from a super GOP level (700, 702, 704, 800, 900), then to a super frame level (902; 904; 908; 909), and then to the regular (individual) frame level (910, 920, 930, 990; 912, 922, 932, 992;  916, 926, 936, 996; 918, 928, 938, 998). At each level, a target number of bits (T1, T2, TL-1, TL) is determined. A target number of bits for a super frame, which is a collection of frames across all channels at a given frame instance (t1, 2t1, 3t1...), is adaptive and is able to address any combination of picture types. Frames of the same picture type for a program are generally assigned the same (or similar) number of bits. Relative program quality can be controlled using a program priority weighting factor (w). Additionally, constraints on target bit rates and minimum and maximum bit rates are provided.

IPC: G06F40/20
Filed: 1999-09-08
Abstract: A system and method for interacting with networked objects, via a computer using utterances, speech processing and natural language processing. A Data Definition File relates networked objects and a speech processor. The Data Definition File encompasses a memory structure relating the networked objects, including grammar files and a natural language processor. The speech processor searches a first grammar file for a matching phrase for the utterance, and for searching a second grammar file for the matching phrase if the matching phrase is not found in the first grammar file. The system also includes a natural language processor for searching a data base for a matching entry for the matching phrase; and an application interface for performing an action associated with the matching entry if the matching entry is found in the database. The system utilizes context-specific grammars, thereby enhancing speech recognition and natural language processing efficiency. Additionally, the system adaptively and interactively "learns" words and phrases, and their associated meanings.

Abstract: The invention provides a fishing bobber having a strike-indicating radio transmitter for transmitting a radio signal to the fisherman when there is a strike on the line. The bobber includes a bobber body adapted to float on a body of water with a fishing line connected to it during use. The radio transmitter is supported by and preferably housed within the bobber. Operatively connected to the transmitter is a transmitter switch for actuating the transmitter. An operating means is connected to the switch for closing the switch in response to a fish exerting tension on the fishing line to thereby operate the radio transmitter so as to broadcast a radio signal to alert the fisherman when a fish strikes. In one preferred form the bobber includes an auxiliary float that can move up and down relative to the bobber for actuating the switch. In another form, the bobber itself is connected to slide up and down on a post which is connected to the fishing line, so that when the post is pulled downwardly by tension on the line the bobber slides upwardly toward the top of the post, thereby closing the transmitter switch. The radio transmitter can also be supported on a transmitter float which floats on the surface of the water next to the bobber and is connected to it electrically.
