Title: Ventilation controller of road tunnel
Inventor: KOYAMA TOSHIHIRO
IPC: E21F1/00
Filed: 1992-04-20
Abstract: PURPOSE:To promote a willing cooperation between a ventilation operation plan of predetermined dust collector air capacity and jet fan unit numbers and a ventilation feedback control performing control over the dust collector air capacity and the jet fan unit number according to tunnel surroundings. CONSTITUTION:A dust collector air capacity planned value Qp and a jet fan unit number planned value Np are corrected by a reference air capacity-unit number selecting means 3 on the basis of a dust collector air capacity actual value Q and a jet fan unit number actual value N, and they are inputted into an output processing means 7 as a dust collector air capacity reference value Q* and a jet fan unit number reference value N*. At this output processing means 7, the dust collector air capacity reference value Q* and the jet fan unit number reference value N* are compensated by a dust collector air capacity correction value  Q and a jet fan unit number correction value  N being outputted from a ventilation feedback control means 4.

Title: A distance learning system providing individual television participation, audio responses, and memory for every student.
Inventor: HARPER GREGORY W
IPC: H04N7/173
Filed: 1995-04-14
Abstract: An interactive distance learning system is disclosed which is characterized by individual attention to each student. A live lecture, transmitted from a remote location (100), is accompanied by questions (480) to gage comprehension by students. The questions and possible answers for student choice are graphically displayed on a video screen (186). Affirmative supportive commentary is prepared prior to the lecture and prerecorded for each of the possible correct and inccorect responses. Each response teaches, confirms and encourages the learning experience. A processor (178), branching codes and a memory device (282, 286) can be used to create a large variety of responses to provide individual responses for students. The transmitted interactive signal can be recorded (294) and remain fully interactive. An extremely flexible, relatively inexpensive system is thus created which uniquely teaches and uniquely addresses the needs of every student.

Title: Distributed circuit switched radiocommunications network.
Inventor: CHANDLER STEPHEN ANTHONY GERAR
IPC: H04B7/15
Filed: 1998-03-30
Abstract: A plurality of transmitting and receiving stations are provided at randomly distributed locations within a telecommunication network, and switching circuitry is provided within the stations themselves for routing of calls between stations in the network utilizing other stations in the network for relaying of such calls where necessary. To this end each station (20) incorporates a call routing control unit acting to select a further station (21) to which a call from a source S to a destination D is to be transmitted for the purpose of relaying the call. The call routing control unit transmits an interrogation signal to be received by other stations in the network within range of the transmitting station (20), and the call routing control unit of each of the other stations (21) transmits an acknowledgement signal when the station (21) is available for relaying a call in response to the interrogation signal received from the station (20), the acknowledgement signal being transmitted after a delay which is indicative of the suitability of the station (21) for relaying the call towards its intended destination. The call routing control unit of the station (20) then selects a station (21) for relaying the call on the basis of receipt of an acknowledgement signal from the station after the least delay.
