Patent CA-2074889-C (CA)
Title: Carrier frequency error detector capable of accurately detecting a carrier frequency error
Inventor: IWASAKI MOTOYA
IPC: H04L27/233
Filed: 1992-07-29
Granted: 1997-12-09
Abstract: On detecting a carrier frequency error in a received signal, a correlation unit (12) detects a correlated signal in signals which a transmission unique word signal in the received signal and a local unique word signal are differentially detected.  A frequency fine detection unit (17) detects a fine frequency error by using the correlated signal and a frame timing signal.  A frequency coarse detection unit (21) detects a coarse frequency error by using the buffered signal from a data buffer (20) and the frame timing signal.  A first adder (25) adds the fine frequency error to the coarse frequency error to a first added signal.  A second adder (31) adds the first added signal to a maximum power frequency detected by a maximum power frequency detection unit (27) to produce the carrier frequency error.

Title: Cheese compositions and processes for preparing the compositions
Inventor: BODOR JANOS
IPC: A23C19/08
Filed: 1992-09-28
Granted: 1998-09-29
Abstract: A nonpasteurized blended full-fat or reduced fat cheese composition having the taste, texture, and consistence similar to the taste, texture, and consistency of the full fat ripened natural cheese. An unripened cheese and a paste containing protein particles are mixed and heated. The heating is conducted at below pasteurization temperatures to ensure bacterial culture's survival. The presence of live bacterial culture allows for further ripening of the cheese; although further ripening is not needed, it is possible if desired.
Patent CA-2083309-C (CA)
Title: Grain processor
Inventor: LE GIGAN DOMINIQUE
IPC: B07B9/00
Filed: 1992-11-19
Granted: 1996-06-18
Abstract: A grain processor for separating and measuring components of a sample of grain as it passes through a rotary sieve having two or more sieving sections having different perforations so that selective separation is made on the basis of the size of the particles in the sample.  The separated particles in each of the sieving sections are passed through a densimetric column containing a stream of pressure-adjustable air generated by a blower, the air stream removing impurities from the separated grain or different density impurities which is channeled into a weighing hopper which measures the weight of the grain or impurities and registers the information in a unit provided with data processing and recording circuits, including microprocessor means.  To control the movement of the air in the separating columns, the motor-driven rotary sieve and the motors coupled to the blowers are provided with tachometers which provide rotational speed pulses to rotation control circuits in the unit which, in turn, provides an input to motor controllers associated with the motors driving the fans and the rotary sieve.  Each of the rotation control circuits is provided with a motor-driven potentiometer which has a rotor rotating together with an optical coded disc which provides an output to adjacently-positioned optical heads providing an input into the unit which registers the position of the potentiometer without requiring a reference reading.  Alternatively, each of the rotation control circuits may use, in lieu of the motor-driven potentiometer, a solid-state electronic interface between the microprocessor means and the motors.  The weighing hoppers and associated scales used in the grain processor are provided with lock-down devices for transit purposes.

Title: Thermostatically-controlled microwave cyclodestruction as a treatment for glaucoma
Inventor: FINGER PAUL T
IPC: A61F9/007
Filed: 1992-04-24
Granted: 2003-07-15
Abstract: A miniaturized microwave applicator comprises a thin-wall metal dielectric-filled waveguide (200) having a thermocouple (208) disposed in a groove (206) in the surface of the dielectric radiating aperture of the waveguide (200). When the aperture is placed in contact with a spot on the outer surface of the sclera overlying the ciliary body to cyclodestruct by heat generated by absorbed microwave energy radiated thereto during a given time, damage due to overheating of the scleral tissue is prevented by the thermocouple (208), which monitors the sclera surface temperature, being used to thermostatically control the microwave energy supplied to the waveguide in a manner that the scleral tissue temperature is maintained substantially constant at a value below that which would cause damage thereto. The desired operation is dependent on the fact that very little of the microwave energy is absorbed by the lower-water-content scleral tissue as it passes therethrough, but is highly absorbed by the underlying high -water-content ciliary-body tissue.

Title: Means of handling multiple sensors in a glucose monitoring instrument system
Inventor: MOULTON JOSEPH L
IPC: B01L99/00
Filed: 1996-02-28
Granted: 2005-10-25
Abstract: A sensor dispensing instrument (20) includes a sensor magazine (26) that contains a plurality of blood glucose sensors (38) disposed in sensor slots (30A-J).      Each of the sensor slots (30A-J) is in fluid communication with a desiccant cavity (50A-J) in which desiccant material is disposed. The front and rear walls (34, 32) of the sensor magazine (26) are sealed with burst foils (40, 42) so as to seal the sensor slots (30A-J) and the desiccant cavities (36A-J). The sensor instrument (20) has an outer housing (22) with a laterally extending magazine opening (24) adapted to receive the sensor magazine (26). A pivot rod (28) is moved through the magazine (26) and is locked into an operating position. The magazine (26) is rotated on the pivot rod (28) until a detent arm (48) on the instrument housing (22) engages a detent groove (50A-J) on the magazine (26) to position the magazine (26) in a sensor feeding position. Once so positioned, a sensor push rod (54) is pushed forward resulting in the push rod (54) piercing the rear burst foil (42) and engaging a sensor (38) in one of the sensor slots (30A-J) to thereby push the sensor (38) out through the front burst foil (40) and into a testing position. While in this testing position, the sensor (38) can be placed in a blood sample that needs to be analyzed. Once the test is completed, the push rod (54) is advanced forward further to thereby eject the used sensor (38) from the sensor handling instrument (20). The push rod (54) then is retracted to a standby position and the sensor magazine (26) is rotated until the detent arm (48) engages another detent groove (50A-J) so that another sensor slot (30A-J) is in alignment with the push rod (54).
