Patent CA-2132207-C (CA)
Inventor: KOSS MICHAEL J
IPC: H04R1/10
Filed: 1993-03-09
Granted: 1999-03-16
Abstract: A dual element headphone (10) including a first acoustic transducer (28) mounted within a first housing so as to direct sound in a certain direction out of the fist housing. The first housing is sized small enough so as to at least partially fit into the cavum concha of a listener's ear, and yet be larger in area  than the entrance of the external acoustic meatus of the listener's ear. A second acoustic transducer (18) is mounted within a second housing. That second housing is substantially larger than the first housing, and overlies at least portion of the auricle of the listener's ear. A crossover circuit divides the electrical signals received by the headphone and transmits signals for higher frequencies to the first smaller transducer and signals for lower frequencies to the second larger transducer. The first transducer may be flexibly mounted for improved comfort and sound fidelity.

Title: Herpesvirus vaccines
Inventor: KNIPE DAVID
IPC: C07K14/03
Filed: 1993-08-02
Granted: 2009-11-24
Abstract: A herpesvirus vaccine comprising a mutated herpesvirus suspended in a pharmaceutically acceptable carrier. The mutated herpesvirus is capable of infecting cells of the mammal to be vaccinated, but incapable of completing a replicative cycle, and it is capable of eliciting a protective immune response in that mammal. The mutation occurs in at least one gene encoding a protein essential for replication of the virus, so that the mutation renders the virus replication defective.

Abstract: A load limited connector that is calibrated to fail at a predetermined approximate tensile load. The connector includes a main body, within which a pin chamber is received, and a secondary body having a shaft that is releasably secured within the pin chamber. At least one breakaway pin, positioned in a pin passageway passing through the pin chamber and into the main body, secures the pin chamber within the main body. When the connector is subjected to tensile loading that exceeds the yielding point of the breakaway pin, failure of the pin occurs resulting in separation of the main body from the secondary body. A pair of torsion pins extend through the pin chamber into the main body to prevent rotation of the pin chamber relative to the main body.

Title: Pumping system
Inventor: NABITY FREDERICK ALAN
IPC: G01L9/00
Filed: 1996-02-12
Granted: 2008-05-20
Abstract: To select a designated bottle in a sampler, the distributor is calibrated as to position and the outlet of the distributor arm is moved over the desired bottle by counting changes in incremental angular movement of the distributor arm until it is over the bottle. The position of the distributor arm is recorded in memory. To calibrate the distributor, the arm is rotated against a stop member in a first direction, then in a second direction and the overrun of in excess of 360 degrees of the motion of the. distributor arm is determined and corrected. A series of random numbers is generated for depositing of samples, the distributor is moved at designated times over the bottles in a random order to deposit a sample and the ordering of bottles is recorded. The rollers of a peristaltic pump are supported to prevent said rollers from compressing said tube more than the thickness of the walls of the tube. A functional module for a bubbler or pH probe or ultrasonic level detector may be connected to the housing.

Abstract: A mobile communication information terminal apparatus comprises: a portable housing; a radio portion for transmitting and receiving radio signals via a radio channel; a control portion which is provided in the housing and connected to the radio portion for transmitting and receiving communication information; and an operating portion which is provided in the housing for supplying communication information to the control portion by means of an operation from outside the housing. A storage device is provided in the housing for storing the communication information and an antenna attachment portion is provided on a surface of the housing. A helical antenna is provided in the antenna attachment portion and electrically connected to the radio portion. A touch pen antenna, comprising an electrical conductor portion having a predetermined length, is attached to the antenna attachment portion and extends along with a central axis of the helical antenna. A tip of the touch pen antenna is tapered like a pencil, i.e. to a point. The electrical conductor is connected electrically to the radio portion when the touch pen antenna is attached to the antenna attachment portion. The operating portion can be accessed from outside. Switching means normally connects the helical antenna to the radio portion when the touch pen antenna is not attached but switches to connect to the radio portion when the former is attached. Upon operation of the switching means, the control portion reads out communication information from the storage device and effects communication via the touch pen antenna.

Abstract: Circuitry for operating an array of light emitting diodes such as in an emergency exit sign in a non-emergency AC mode while concurrently charging and maintaining the charge of a low-voltage battery used to drive the array in an emergency mode, the circuitry also allows operation of the same LED array in the emergency mode from the low-voltage battery.  The advantages of the invention are realized in part through provision within the circuitry of a boost converter wherein the LED array and the battery are connected across the output of the usual boost circuit output capacitor, thereby allowing connection of the array and the battery in series to simplify operation from line power and to allow the same current limited source to operate the array and simultaneously charge the battery through the same current path.  The functions so provided can be embodied in a form which allows all circuitry components including the battery to be mounted on a single, compact substrate such as a printed circuit board.

Abstract: A network node comprises a cross-connect switch and a single signal quality monitor connected to one of the output ports of the cross-connect switch. The switch is controlled by a processor to establish connections. The processor is responsive to a request message from another network node for causing the switch to establish a connection between one of the input ports of the switch specified by the request message and the signal quality monitor and returns a reply message indicating a quality level of a signal appearing at the input port. A switched telecommunications network, such as Internet, may be used for transmission of the request and reply messages. Alternatively, the request and reply messages may be multiplexed with traffic signals.
