Patent CA-2092166-A1 (CA)
Inventor: SAITO SHUICHI
IPC: H04L12/46
Filed: 1993-03-22
Abstract: In a router device of the present invention, the routing controller refers to the routing address table to determine whether the received frame is to be routed (whether the frame passes through two or more router devices, for example).  The multiplication controller multiplies the frame selected as the subject of routing and has the path controller set paths between router devices for transmission of the multiplied frames.  The frame for which a path is set is transmitted with the destination address of the router device as the other party of communication.  When a multiplied frame is received, the multiplication controller extracts an ordinary frame from the multiplied frame and sends it to the device indicated by the original destination address.

Abstract: A method for prescribing a prism factor for eyeglasses for substantially correcting vertical and/or horizontal diplopia or double vision problems, which includes having a patient positioned for gazing at a target image while holding their head in a substantially fixed position, and then closing their affected eye for a period of time, whereafter they are instructed to open the affected eye and immediately report upon where a double image occurs upon a measurement grid associated with the target image continuing to be observed by their other eye, for permitting a prism factor to be prescribed relative to the measured distance between the target and double image created by the defective eye.       The minimum necessary prism factor for correcting the vision of the defective eye to provide for merger of the target image observed by the other eye with that of the defective eye upon opening, permits maximization of the involvement of the eye muscles of the defective eye in combination with the prescribed prism for substantially extending the range of correction of the diplopia problem.

Title: Floor cleaning and polishing equipment
Inventor: BROWN DENNIS J
IPC: A47L11/162
Filed: 1994-07-26
Abstract: A combined floor cleaning and floor polishing machine comprises a motor housing (2), an inclined operator handle (2), a base (3) with castors (4) and a motor-operated shaft (5) for a rotating disc (7) supporting interchangeably a cleaning pad or polishing pad, so that the machine weight is carried partly on the pad and partly on the castors (4).        If the handle (2) is tilted the machine moves laterally to one side or other in dependence upon the direction of tilt. The use of elastomeric torsion blocks (8) to connect the motor housing (1) to the base (3) provides an elastic resistive force in either tilt direction and thus improves controllability of the cleaning/polishing movement in either lateral direction, by a simple, robust and inexpensive construction.

Patent CA-2131295-A1 (CA)
Inventor: ROSCH REINHARD W
IPC: H04M19/00
Filed: 1993-03-17
Abstract: A telephone line interface circuit comprises two unity gain d.c. amplifiers (132, 134) having outputs d.c. coupled via feed resistors to the line wires. Currents in the feed resistors are monitored via a digital control circuit (152), which can be programmed to provide desired operating conditions. The control circuit controls, via D-A converters (158, 161), currents passed by current sources (142,148) through resistors (140,146) at inputs of the d.c. amplifiers, thereby determining voltages at the amplifier inputs and hence on the line wires. These d.c. voltages are smoothed by capacitors (136,138) used for coupling an a.c. signal to the d.c. amplifiers. The voltage control facilitates adaptive adjustment of the line interface circuit to the line in dependence upon the monitored currents.
