Patent CA-2006554-A1 (CA)
IPC: H04M19/08
Filed: 1989-12-22
Abstract: Power supply switch (17) for electrical equipment (1) combining in one supply an accumulator (16) and another source of electrical energy (15) which this accumulator is able temporarily to replace or to interface. Switching means (25) put the accumulator in and out of circuit, connecting it up to at least one terminal (A) for powering the equipment, and to which the other source is also connected. Control means (27) connect up the accumulator via the switching means when the terminal (A) is brought to a specified potential by the power supply, and blocking means (29) act on the control means in order to trigger the disconnection of the accumulator when and for as long as the said terminal (A) is at a potential lower than a specified threshold value.

Filed: 1990-03-15
Abstract: SPIN/STALL DETECTOR FOR AN ELECTRICALLY       PROPELLED TRACTION VEHICLE                 ABSTRACT OF THE DISCLOSURE For a traction vehicle having two wheels driven by separate electric motors, a spin/stall condition is indicated if one of the wheels is rotating faster than a predetermined reference speed while the other wheel is not rotating, and a total stall condition is indicated if neither wheel is rotating and the magnitude of motor current exceeds a predetermined high level. Correction of any spin/stall condition is attempted by temporarily connecting a power resistor across the motor driving the spinning wheel, whereupon current (and hence torque) in the motor driving the stalled wheel will increase. Once a total stall is indicated, it is allowed to continue for a maximum period of time that varies inversely with the motor current magnitude, and if such condition is not earlier corrected motor damage is avoided by deenergizing both motors on the expiration of this period.

Title: System for separating speech from background noise
Inventor: HUNT MELVYN
IPC: G10L21/0208
Filed: 1990-12-06
Abstract: Abstract A digital signal processing system applies an adaptive filtering technique to sequences of energy estimates in each of two signal channels, one channel containing speech and environmental noise and the other channel containing primarily the same environmental noise. From the channel containing primarily environmental noise, a prediction is made of the energy of that noise in the channel containing both the speech and that noise so that the noise can be extracted from the mixture of speech and noise.  The result is that the speech will be more easily recognizable by either human listeners or speech recognition systems.

Title: Liftys communication hangers
Inventor: SOMERS DAN-EL F
IPC: F16L3/00
Filed: 1991-06-03
Abstract: ABSTRACT Re-Liftys Communication Hanger It is a device for suspending all types of communication cables  off  the  ceiling  to  achieve  minimum  adequate clearance above lightings and suspended ceiling.  For this purpose  it  consists  of  a  light  weight,  heavy  duty galvinized specially coated wire approximately 12 ga to 1/4" in diameter and 10-30" in length bent at one end to form a loop which is for holding the communication cables and taking the stress of the cables off the ceiling tiles and the ceiling wire. The end of this loop is designed to allow  it  to  be  locked or unlocked  for  flexibility to accomodate additional cables at a later stage. The other end is hook shaped to allow this device to be hooked to a support which may be eg. an existing conduit or existing angle bracket.  There is also no stress on the cable jacket due  to  the  loose  design  of  the  locking loop.  These communication cable hangers will be used  singly or  in multiples by spacing them  in  linear intervals at approximately 3 to 4 feet apart with loops facing each other and at a consistent length from hanger bracket.
