Title: Network synchronization for sdh/sonet
Inventor: YAZAKI MASAHIRO
IPC: H04J3/06
Filed: 1998-10-14
Abstract: In a synchronous network composed of a plurality of nodes that are connected in ring network topology and have unique codes respectively assigned thereto, stable and reliable synchronization and the simplified timing design can be easily achieved.  At each of the nodes, a signal having a unique code for identifying a source node of a current synchronization clock is transmitted to an adjacent node.  A local clock of the node is selected from a plurality of clocks depending on whether a unique code assigned to the node is identical to the unique code included in a received signal.

Title: Vehicle occupant position sensor
Inventor: STANLEY JAMES GREG
IPC: B60R21/015
Filed: 1998-02-05
Abstract: A plurality of ultrasonic transmitters (12) at distinct locations and with distinct transmitting frequencies, direct beams of ultrasonic sound waves at one or more detection regions (16) of space. The amplitude of the ultrasonic sound waves is sufficient to generate from each detection region (16) a sound wave (17) having a frequency corresponding to the difference of the frequencies of the respective ultrasonic sound waves. A receiver (18) disposed proximate to the ultrasonic transmitters detects the generated sound wave. An object occupying the detection region blocks one or more of the beams, and is detected therein when the magitude of the generated sound wave (17) is below a threshold. In another aspect of the instant invention, the ultrasonic transmitters (12) are adapted to transmit pulses forming relatively broad spherical wavefronts (38) which intersect to form a circular detection region which propagate with time, thereby enabling the detection of a profile of an object.
