Patent CA-2160750-A1 (CA)
Inventor: ALBERTH WILLIAM P JR
IPC: H03G3/30
Filed: 1995-10-17
Abstract: A transmitter (107) includes amplifying circuitry (203) and control circuitry (215, 217, 219) for biasing the amplifying circuitry (203) so that it operates closer to saturation with increased efficiency. The gate voltage signal (213), which provides a gate bias, is coupled to the amplifying circuitry (203) and is dynamically varied by the processor circuitry (219) in response to the value of the amplifier control voltage (211) coupled to the amplifying circuitry (203). The amplifier control voltage (211), which has a value for maintaining the output power of the amplifying circuitry (203) at a constant, is produced by the integrating circuitry (217) in response to a comparison of the detected power output signal (216) produced by the detecting circuitry (215) and the power output control signal (218) produced by the processor circuitry (219). Efficiency is realized by dynamically varying the gate voltage signal (213) to its largest magnitude so that the amplifying circuitry (203) may operate as close to saturation as possible while still maintaining a constant output power.

Patent CA-2167745-A1 (CA)
Inventor: HERZBERG HANAN
IPC: H04L25/49
Filed: 1996-01-22
Abstract: A modem that matches itself to a central office codec to which it is connected and incorporates encoding of the data. An echo canceller following the central office codec subtracts an estimate of the echo introduced in the central offices. More particularly, digital data applied to the modem is multi-level encoded and mapped onto a subset of the levels recognized by the central office codec. In an illustrative embodiment, the multi-level encoding encodes the two least significant bits in the binary representation of the levels delivered by the modem. The least significant bit is encoded with a code that is more robust than the code of the next-to-least significant bit, in recognition of the fact that errors in the least significant bit are much more likely. The corresponding echo canceller in the network first estimates the echo and subtracts it from the signal applied to the digital network by the central office. Thereafter, a decoder decodes the received signal in stages. In the first stage, the least significant bit of symbols is identified based on a first error correcting code. In the second stage the remaining bits of the symbols are determined, with the aid of a second error correcting code and the results of the first stage. Block or convolutional encoding can be used.

Title: A knitted sweater or corresponding garment article, and a method of manufacturing it
Inventor: PEDERSEN PETER
IPC: A41D31/00
Filed: 1994-08-05
Abstract: A sweater or similar knitwear product is disclosed, mainly consisting of a knitwear fabric of the yarn used for the so-called cowboy or denim cloth, viz. the very wear resistant, indigo dyed cotton yarn.  Such a sweater will be softer than the denim cloth, but it is desirable that both a collar and the button-bands, i.e. the front side portions holding the closing system, be made of a more rigid material. Advantageously, this material may consist of the woven denim cloth.  The knitted fabric will shrink considerably in the wash, and it is complicated to stitch-on the woven fabric so as to avoid future wrinkling.  According to the invention the knitwear parts for the products are knitted as fully fashioned pieces with pronounced loose knitting, and these pieces are subjected to a washing and drying treatment, whereby that shrink to a desirable size and density, and only thereafter the woven pieces are attached by stitching.  This stitching may now be effected fully conventionally, as the said wrinkling will automatically be avoided.

Title: Tractor pump jet
Inventor: VARNEY A MICHAEL
IPC: B63H1/28
Filed: 1996-08-21
Abstract: A marine pump jet includes a rotor located upstream and in front of the rotor drive mechanism. The lower unit of the tractor pump jet has a rotor housing which substantially surrounds the rotor and a stator housing located downstream, of the rotor and rotor housing. The drive shaft extending from the powerhead of an outboard motor enters the stator hub where a pinion gear engages a crown gear attached to the rotor shaft. This places the rotor drive mechanism downstream of the rotor so that the rotor is substantially the first mechanical element that water initially comes into contact with. The inlet opening of the pump jet is larger than the outlet opening at the outlet of the stator housing. Because the rotor operates on essentially undisturbed, non-turbulent water, it is more efficient than traditional pump jets where the rotor is located aft of the drive mechanism. According to an alternative embodiment, a reverse shifting mechanism permits the Tractor Pump Jet to operate in either the forward or reverse direction.

Title: Home security system for detecting an intrusion into a monitored area by an infrared detector
Inventor: DOCKERY DEVAN
IPC: G08B25/10
Filed: 1996-09-23
Abstract: A security system having a free-standing intrusion detector. The free standing intrusion detector has a transmitter coupled with a portable receiver to alert a homeowner that an intrusion has taken place or occurred within a pre-set time period. The area under surveillance is monitored by an infrared detector which activates the transmitter upon the receipt of abrupt differences in infrared radiation levels, associated with the presence of a warm body in an otherwise equilibrated environment. A radio signal is emitted by the transmitter which is received by the portable hand-held remote receiver. A first signal, indicating that an intrusion has been detected in the monitored areas, is displayed on the receiver for a preselected period of time. After the preselected period of time has elapsed, a second signal is generated to indicate that the intrusion took place at a time less than the preselected period of time and that the probability of the intruder still being present is great. Once the intrusion detector is activated, the signal is continuously transmitted to the portable receiver until the intrusion detector has been reset.
