Patent CA-2153174-A1 (CA)
Title: A wide area fiber and tv cable fast packet cell network
Inventor: BARAN PAUL
IPC: H04N7/14
Filed: 1993-12-21
Abstract: 53 byte length ATM compliant cells are transmitted over a digital optical fiber path to interconnect with a coaxial feeder cable TV system to support two-way digital services at a plurality of sites connected to the TV cable system. At the point of interconnection between the fiber optic path and the cable TV feeder subsystem, digital signals are converted to a UHF rf carrier frequency above the cutoff pass-band of the analog signal feeder amplifier carrying TV broadcast signals. This rf carrier conveys a high data rate digitally modulated signal limited to sections of feeder cable between the cable TV broadcast channel amplifiers. In-house access to this UHF carrier signal is via the normal TV cable tap and drop cable to an SIU, located near the subscriber's TV set. The feeder cable and the passive taps used in cable TV practice have a higher cutoff frequency than the feeder amplifiers themselves. This allows passage of a UHF signal over the feeder cable. Low pass filters at the feeder amplifiers prevent this UHF signal from being shorted out by the in-cable amplifiers. Each SIU so connected sends and receives the UHF carrier signal, which conveys the ATM type cells. Each cell' s payload contains the local address of the source and destination of that cell. Each SIU decodes each cell's address and accepts only those cells that are for itself. The SIUs speak to and receive signals from an FTU located at the TV cable headend or at a fiber connection node. The common channel conveying the ATM cells alternatively sends and receives cells in a ping-pong fashion.

Patent CA-2172068-A1 (CA)
Title: Wide-angle motion detector with close-in reflector
Inventor: LEE WADE P
IPC: G01V8/10
Filed: 1994-10-04
Abstract: A passive infrared motion detector with wide field of view extending to greater than 180 degrees that can be achieved in a cost-effective manner using a single sensor. The motion detector includes a planar infrared sensor (12, 46) and two or more infrared-reflecting faces (16, 17 and 41, 42) which are positioned close to and overlying at least a portion of the sensor.  The reflecting faces are configured so that their ends proximal to the sensor overlie the sensor at its midportion and the faces extend from the  midportion in different directions away from one another to reflect radiation to the sensor from different sides of the sensor. In one embodiment the reflecting faces (16, 17)  form a generally prismoidal shape (11).  In another embodiment the proximal ends (43, 44) of a pair of faces (41, 42) are displaced laterally from one another over the sensor so that the overlying faces obstruct a portion (51, 53) of the sensor and leave a portion (52, 54)  unobstructed to form a  checkerboard  pattern of obstructed and  unobstructed regions.  The reflecting faces are positioned close to the sensor with their proximal ends spaced apart from the sensor at most a distance  comparable  to a characteristic transverse dimension of the sensor.  Because of the close proximity of the mirror to the sensor, the area of the reflecting surfaces need not be very large and may be made comparatively  small.  The mirror surfaces deflect infrared energy from a suitable focusing means (13) onto the sensor from a plurality of zones so as to extend the lateral extremities of the motion detector field of view.  Configured in this way, motion detectors may be provided with viewing angles at least up to 220 degrees using a single sensor.  The reflecting faces may be formed together with a base from a single member (31, 61), which also is shaped to receive and hold an integrated-circuit sensor package (22).  The unitary reflecting head and base portion can be mounted directly on a printed circuit board (34) and the reflecting faces are automatically aligned correctly over the sensor.

Patent CA-2198524-A1 (CA)
Inventor: KEIM NORBERT
IPC: E01H1/08
Filed: 1997-02-26
Abstract: The blowing and suction device of the present invention is especially designed for vacuum choppers used for picking up and shredding leaves, grass, refuse, and similar material. The device consists of a blower casing and a impeller inside receiving a rotary motion from a drive unit for sucking in air through an intake opening in the blower casing and for expelling the air through an exhaust opening in the blower casing.  The impeller has a circular bottom plate with a centrally positioned bearing for the drive shaft; on the side of the bearing facing away from the drive shaft there are vertically projecting fan blades which extend radially from the centre outwards to the edge of the bottom plate in the pattern of a tangential fan.  Two or more, but at the most every second one, of the fan blades carry on their surface facing away from the bottom plate a chopping blade projecting in the direction of the air suction.  The advantage obtained by the invention is essentially that the chopping blades pre-shred the material sucked in, the distance between them being sufficient to prevent clogging.  Only the pre-shredded material arrives in the vicinity of the fan blades, where further shredding of the material then takes place.  As a result, no pieces arrive which would be large enough to become stuck between the fan blades.
