Patent CA-2027561-C (CA)
Title: Improvements in diagnosis by means of fluorescent light emission from tissue
Inventor: ANDERSSON-ENGELS STEFAN
IPC: A61B5/1455
Filed: 1990-02-21
Granted: 2001-02-20
Abstract: A sample (1) is irradiated by a pulse from a laser (2), creating fluorescence radiation, which is brought, in imaging relation or otherwise, to a detector (6) sensing from the same sample (1) in a plurality of spectral intervals (6A-6D), for obtaining intensity values. The radiation may be sensed in imaging relation, creating a multiplicity of said pluralities. The spectral intervals may be wavelength defined by passband filters (5A-5D) or time interval defined time spectral intervals controlled by a computer (7), which makes a numerical evaluation comprising a division. The tissue character may then be evaluated from the evaluation.
Patent CA-2030014-C (CA)
Inventor: BACKUS ROBERT O
IPC: F16D3/00
Filed: 1990-11-14
Granted: 1994-10-11
Abstract: A flexural pivot is configured as a multi-piece device which is specifically configured to tolerate vibration and shock loading.  The flex pivot described uses pre-formed unitary (one-piece) support structures which have integral undercut areas, diametrically opposed slots for flexural member placement and key ways and the like, and near net shape geometry.  The flexural members are pre-brazed to facilitate the assembly process.  The design of the pre-formed support structures eliminates brazed joints which are common locations of fracture due to vibration and shock loading, resulting in a significantly strengthened pivot.  The overall configuration and method described provides an economical flex pivot, whereby the flex pivots are accessible for applications which have not heretofore been feasible.

Title: Constant-current integrated power supply
Inventor: LEWYN LANNY L
IPC: H02J1/00
Filed: 1991-11-20
Granted: 1998-08-11
Abstract: A positive energizing voltage is converted by a pair of buffer capacitors and a filter capacitor to a particular negative potential. Each buffer capacitor is charged during a half clock signal cycle, the first during positive half cycles and the second during negative half cycles. Each buffer capacitor discharges through a circuit including a switch which has at each instant a variable state of conductivity dependent upon the magnitude of the negative potential at that instant. This magnitude is varied in accordance with the variations in the state of the switch conductivity to regulate the negative potential at a particular value, as opposed to the magnitude changing, as is the tendency in prior art CMOS circuits. The filter capacitor is charged by the negative potential and is discharged to the load briefly during every change in the clock signal polarity.

Title: Fsk receiver
Inventor: MINAMI YOICHIRO
IPC: H04L27/152
Filed: 1992-04-08
Granted: 1999-01-19
Abstract: An FSK (Frequency Shift Keying) receiver capable of reducing the deterioration of sensitivity suppression ascribable to interference waves despite the use of an orthogonal detection type reception system. Mixers for generating baseband signals are followed by high pass filters, low pass filters, and an orthogonal detection modulator. The baseband signals from the mixers are each applied to respective one of the high pass filters while the output signals of the high pass filters are fed to the associated low pass filters. The demodulator processes the output signal of the low pass filters to produce a demodulated signal. The high pass filters attenuate the demodulated signals of interference waves.

Title: Band management system in communication
Inventor: TACHIBANA TETSUO
IPC: H04Q11/04
Filed: 1992-07-03
Granted: 1997-11-18
Abstract: The invention relates to a technology with which a call process, a band setting process in particular, from a unit of terminal equipment to a network can be effectively performed.  In a communication system, a communication band required by a unit of terminal equipment is secured by transmitting a SETUP message to a network from the terminal equipment, as in the case of a call procedure in B-ISDN, etc.  When a call is made by the communication control unit of the terminal equipment connected to the network, if the securing of a band in the network is impossible the call is cut off.  However, if the band area in the network is insufficient for an initial band value stored in the SETUP message, a revised band value is produced by subtracting a certain value from the initial band value, and a SETUP message with the revised band value is retransmitted to the network.

Inventor: VANDERSPOOL JAN PETER II
IPC: H04W92/00
Filed: 1992-08-24
Granted: 1996-11-12
Abstract: A control station (12) initiates a system timing signal transmission which is re-transmitted from a satellite (14).  In response to receiving the re-transmitted system timing signal, the control station (12) then generates a time correction factor signal which is distributed to a plurality of transmission stations (16, 18).  The transmission stations (16, 18) in response to receiving the system timing signal transmission and the time correction factor signal distributed from the control station (12) generate a time adjustment factor signal which is used to correct the local transmission clocks (36, 36'), thereby providing time synchronization of data transmissions generated from the transmission stations (16,18).

Title: Swath turner
Inventor: GERBRANDT HAROLD F
IPC: A01D78/00
Filed: 1994-06-20
Granted: 2002-09-10
Abstract: A swath turner for inverting a swath or windrow of cut crop has a pickup followed by a moldboard. The moldboard extends rearwardly from one side of the pickup and across the direction of travel. It engages one side of the swath or windrow as it leaves the pickup discharge and inverts the swath or windrow before it falls on the ground. As the inverted swath or windrow is deposited onto the ground, the tail end of the moldboard forces it down on the ground. A swath setter may follow the inverter to set the swath firmly to avoid subsequent wind losses.
