IPC: H04N7/15
Filed: 1992-09-01
Abstract: PURPOSE:To prevent the careless changeover of a picture during utterance and the changeover of a picture caused frequently by inhibiting the changeover to other picture till the end of utterance in the picture changeover resulting from detecting a voice signal. CONSTITUTION:The utterance in plural conference rooms 1a-1n connecting by communication lines 2a-2n is discriminated at a voice detection section 4 depending on a voice level, and an utterance party discrimination section 5 selects a specific conference room among conference rooms making utterance.

Title: On-line automatic measuring method for pipe length
Inventor: NAKAMURA YUZURU
IPC: G01B17/00
Filed: 1994-09-01
Abstract: PURPOSE: To measure the length of a steel pipe automatically, on-line, and at a high speed by extracting a sound pressure variation inside the steel pipe caused by an acoustic signal with an acoustic sensor set at the top of the steel pipe. CONSTITUTION: When an acoustic signal is inputted inside a steel pipe of which both ends are closed, a standing wave governs according to the length of the steel pipe for a very short period. When a steel pipe 3 is closed, both ends of it become the nodes of standing wave and, at that point, a sound pressure variation becomes the maximum. Therefore, when an external noise by a vibration excitor 4 is very high as in a sand column forming civil engineering work, a sound pressure variation in the steel pipe 3 can be sampled at a high SN ratio without having any effect on the work by merely installing one acoustic sensor to the upper end part of the steel pipe. Thus, in principle, the length of the steel pipe 3 can be measured by analyzing a high pressure signal sampled by the acoustic sensor and identifying the component of a standing wave included in the signal.
