Patent CA-2052314-C (CA)
Inventor: PARTYKA ANDRZEJ
IPC: H04B1/707
Filed: 1991-09-26
Granted: 2001-07-17
Abstract: A spread spectrum communication system for direct sequence transmission of digital information having a modulation format which is particularly suitable for indoor communication within residential, office and industrial structures. The modulation format combines BPSK or MSK spreading with FM carrier modulation by data bits and a carrier frequency shift whose magnitude is related to both a chip rate and a spreading sequence length. The carrier, chip clock and data clock are all synchronous and the sequence length is an integral submultiple of the bit length. The system reduces the frequency error between the transmitter chip clock and the receiver chip clock to permit the elimination of a code phase tracking loop in the receiver to reduce the receiver complexity. The receiver has an extended dynamic range which makes possible the reception of very strong signal without an automatic gain control loop (AGC) as well as reducing the time needed for code phase acquisition. The transmission system is highly resistant to CW jamming and short distance multipath effects.

Abstract: A headbox for a papermaking machine has an outlet channel having the width of the machine which is limited by a rigid channel wall and by a movable channel wall.  The movable channel wall is part of a channel-wall support.  Between the latter and a supporting member, there is a pressure cushion which counteracts the pressure prevailing in the outlet channel.  A lift device is swingably mounted, at one end, on the rigid headbox housing and, on the other end, on the channel-wall support.  In each of the two end walls of the channel-wall support, there is provided a spherical joint, the center point of which lies in a plane extending through the end point of the channel width.  The lift device is coupled to the spherical joint by means of a C-shaped spindle head.

Granted: 1996-11-12
Abstract: A method of water-proofing a connected portion of electric wires is disclosed which improves the efficiency of water-proofing and prevents the connected portion from becoming enlarged after working.  An injector 10 filled with a water-proof insulation adhesion agent 11 is disposed above a tapping roll 7 of a known tape winder so that a nozzle 9 of the injector 10 is directed to the roll 7.  A water-proof sheet 1 cut in a desired size is fed on the tapping roll 7. A predetermined amount of the adhesion agent is dropped on the sheet 1 from the nozzle 9 to form a deposit 2 of the adhesion agent.  A supplementary sheet 4 made of a water-proof insulation material is applied to the connected portion 3 and then the connected portion 3 with the supplementary sheet 4 is put on the deposit 2 to form a sandwich type construction in which the portion 3 is disposed between the sheets 1 and 4.  Then, the connected portion 3 is pushed down into a slot 8 of the tapping roll 7.  The sheets 1 and 4 are wound around the connected portion 3 to seal it by rotating the roll 7.

Title: Improved device and method of separating and assaying whole blood
Inventor: CHU AMY H
IPC: G01N33/52
Filed: 1992-10-02
Granted: 2004-01-20
Abstract: An improved device and method of separating the cellular components of whole blood from plasma or serum and assaying the plasma or serum for a predetermined soluble constituent are disclosed. The device includes a filter pad, that separates the cellular components of whole blood from the serum or plasma, and a test pad, that assays the serum or plasma for a predetermined soluble constituent. The filter pad effectively separates and retains cellular components of the whole blood sample, thereby eliminating assay interference by the cellular components of whole blood. The method includes contacting the whole blood with a test device including a filter pad comprising a suitable carrier matrix homogeneously incorporating therein a separating reagent composition comprising a) separating reagent, like an agglutinin, such as a blood type nonspecific lectin; a coagulant, such as a thrombin or a thrombin-like compound; or a mixture thereof, and b) a nonhemolytic surfactant, like an ethoxylated or propoxylated nonionic or anionic surfactant, such that the cellular components of the whole blood are separated from the plasma or serum as the blood permeates through the filter pad, The essentially cell-free plasma or serum then saturates a test pad that is in contact with the filter pad. After the plasma or serum saturates the test pad, the test pad is examined for a qualitative or quantitative response to a predetermined soluble constituent of the whole blood.

Title: Reflective and transmissive document reading apparatus and a method of reading a document
Inventor: TANAKA KENJI
IPC: H04N1/10
Filed: 1993-05-13
Granted: 2000-07-18
Abstract: A scanner provided with means for reading both reflective and transmissive documents, comprises: two CCD sensors, one for reflection mode to read reflective documents, and the other for transmission mode to read transmissive documents, disposed respectively on one side of a light source, and on the opposite side thereto with a document table therebetween; and a reflective/transmissive document mode discriminating means wherein, when a light source is turned on, a judgment is made on whether or not light to be transmitted is blocked. The circuits of CCD sensors can be automatically changed between transmission mode and reflection mode. Specifically, a reading window disposed in a transmissive document reading unit is equipped in a detachable manner with either a blocking member for preventing light from entering the transmissive document reading unit, or a diffusing plate for scattering incident light so as to introduce uniform light into said transmissive document reading unit. Alternatively, light from light sources is color-separated by dichroic mirrors into blue, red and green light beams, and thus obtained desirable light is reflected and transmitted through a beam splitter to read a document with no diffusing plate. In this case, light beams are aligned in proceeding direction by the dichroic mirrors, so that color reproduction performance of an original document having unevenness can be improved.

Granted: 2003-09-30
Abstract: A battery pack having a detection recess formed along a center line of a bottom surface arranged such that the detection recess is engaged with a convexed portion of a battery charger.      Therefore, whether or not the battery pack is properly attached to the battery charger can easily be detected by the inclination of the battery pack about the center line. Further, a battery pack is arranged such that an aperture is formed on an outer surface of the battery pack and an output terminal is inwardly disposed on the aperture. Therefore, damage to the batteries in the battery pack caused by a short-circuit resulting from products made of conductive metal material such as a key ring, necklace, or chain contacting both of the output terminals, as occurs when terminals are disposed on the outer surface of the battery pack, can be prevented. Furthermore, the battery pack includes apertures with output terminals disposed therein for discharging dust or the like away from the terminals into the interior of the casing or out of the casing through a hole.      Therefore, the accumulation of dust or the like within the apertures and upon the output terminals is prevented.

Abstract: A differential magnetic wheel detector is disclosed which identifies the presence and direction of a railway vehicle.  The wheel detector includes a primary winding, a secondary winding and signal processing circuitry.  The primary winding is excited by a source of AC energy to produce a magnetic flux in the wheel of the railway vehicle.  The secondary winding senses a change in voltage induced by the magnetic flux in the railway wheel.  The secondary winding includes two coils in a differential bridge which prevents external factors from interfering with the sensing of the wheel.  The signal processing device transforms the voltage change into a signal identifying the presence and direction of the railway vehicle.
