Patent CA-2251585-A1 (CA)
Inventor: ALLEN MARK G
IPC: B81B5/00
Filed: 1996-10-30
Abstract: A magnetic relay system (10) is implemented to act as a relay driven by a magnetic flux yet cabable of production through micromachining. The magnetic relay system (10) has an electromagnet (15), a movable plate (18), and conductive contacts (19, 22). The contacts are connected to the circuits of outside electrical systems that are to be controlled by the switching of the relay system (10). The plate (18) is movable allowing it to engage both contacts (19, 22) and allow current flow between the contacts (19, 22) or to disengage both contacts (19, 22) and prevent current flow between the contacts (19, 22). The electromagnet (15) provides a sufficient magnetic flux at desired times to move the movable plate (18) and thereby controls whether the movable plate (18) is engaged with the contacts (19, 22). The electromagnet (15), movable plate (18), and the conductive contacts (19, 22) may be formed on a substrate (23) capable of construction using microfabrication techniques.

Title: Mirror failure detector for high power lasers
Inventor: ZAMEL JAMES M
IPC: H01S3/00
Filed: 1998-11-12
Abstract: A detector 50 is included in a laser apparatus for generating a high energy laser beam to protect against the uncontrolled escape of the high energy laser beam from its prescribed optical path 40. The high energy laser beam proceeds along the optical path 40 and is directed to a work site 44 by a series of reflective surfaces in its path 26 and 30. The series of reflective surfaces function to change the path 14 of the beam 32 from the generating source to the work station 44. Associated with each of the reflective surfaces is a detector 50 which comprises a conductive frame 51 having a front face 52 and a back face 54. The back face 54 is equipped with a thermal sensor 60 which is positioned in a base portion 64 of the heat conductive frame 51. The detector is equipped with cooling means 58 and 66 for maintaining the threshold temperature. The sensor 60 which is affixed to the base portion 64 having a controlled thickness is preset at a threshold temperature such that in the event the reflective surfaces 26 or 30 breaks or otherwise fails permitting the beam 34 to strike the heat conductive frame 51 it would cause sudden rise in temperature of the sensor which would trigger the control circuit 69 to shut down the power supply 92 that energizes the high energy gain module 12.

IPC: G06T9/00
Filed: 1998-06-26
Abstract: Pixel data are encoded as grouping element data devoid of end of line indications. Input data analysing means is arranged to generate digits which are representative both of data distributions and data occurrences and processing means identify groupings of digits of mutually similar value. In one embodiment the image is analysed for determining the occurrences of value 0, value 1, ..., value 15 of the pixels and these values are ranked according to their occurrence figures. Values which occur most frequently are coded with relatively many "0" bits and values which occur less frequently are coded with relatively many "1"  bits. The bit planes are then entropy encoded. Also each bit plane can be encoded by encoding the positions and sizes of squares of elements of bit value "1 ".

Inventor: YOKOTA TAKESHI
IPC: C23C26/00
Filed: 1998-11-10
Abstract: An excellent antibacterial property is afforded upon a metallic article by simple steps of coating a dispersion liquid or a solution of fine particles made of an antibacterial ingredient on the surface of the metallic article and pressing the resulting coated surface of the metallic article under a non-heated condition or rubbing the resulting coated surface of the metallic article. In addition, a conventional rolling step or the like can be used itself without any change in the above treatment, which is economically extremely advantageous. Furthermore, since the antibacterial metallic article according to the present invention is obtained under the non-heated condition, the antibacterial ingredient is not deteriorated. Further, since the antibacterial property is not lost through some abrasion, excellent antibacterial property can be exhibited over an extended time period. Further, there is no fear that surface characteristics of the metallic article, for example, a tone of color will change.

Title: Method and apparatus for monitoring dispersive-wave energy to indicate and optimize soliton transmission performance
Inventor: SAUNDERS ROSS ALEXANDER
IPC: H04B10/08
Filed: 1999-08-04
Abstract: An embodiment includes a gating device, a feedback device and a control device. Soliton pulses are received by the gating device, which detects and monitors a dispersive-wave between adjacent soliton pulses using a timing circuit. The timing circuit typically provides a gating signal offset in phase from the soliton pulses in order to trigger the gating device. Triggering the gating device allows the dispersive-wave to be accessed and monitored between adjacent soliton pulses. The feedback device, typically using detectors and processing circuitry, measures the energy of the soliton pulses and the energy of dispersive wave. The feedback determines a ratio of the energy levels as an indication of soliton-pulse transmission performance. The indication is provided to the control device as a feedback signal so that the control device can appropriately adjust characteristics of the soliton pulses and improve or optimize transmission performance.

Title: A method and system for providing wireless mobile server and peer-to-peer services with dynamic dns update
Inventor: WANG JIN
IPC: G06F13/00
Filed: 1999-10-25
Abstract: A method and communications system provide data and voice services to subscribers at mobile terminals using dynamic IP address assignment and dynamic DNS update. A visited network dynamically assigns one of its IP addresses to a mobile terminal away from its home network accessing the visited network as a session IP address. The visited network transmits the assigned IP address to the home network of the mobile terminal over a private network. The home network associates the assigned IP address from the visited network with the host name of the mobile terminal in a DNS server of the home network and sends the host name to the visited network, although the visited network may already have received the host name from the mobile terminal. The visited network associates the host name of the mobile terminal with the assigned IP address its DNS server. Upon termination of the call by the mobile terminal, the visited network disassociates the assigned IP address with the host name in its DNS server and instructs the home network to do the same.

Title: Method for controlled optimization of enterprise planning models
Inventor: OUIMET KENNETH J
IPC: G06Q10/00
Filed: 1998-05-21
Abstract: A computer-implemented method and system for controlled optimization of enterprise planning models are provided. This is accomplished by first defining an auxiliary objective function, which depends on the same variables as the model, or a subset thereof. An effective objective function is then constructed from the primary objective function by subtracting the auxiliary objective function multiplied by a weighting factor. The effective objective function is then optimized for a whole range of weighting values, yielding a table that describes how the primary objective function varies according to different values of the weighting factor. Optimization of the effective objective function with a given value of the weighting factor results in a particular value for the auxiliary objective. Thus, this computed table essentially provides a relationship between different realized values of the primary objective, the auxiliary objective, and all the variables of the enterprise planning model. The user is further provided with a way to specify a target value for the auxiliary objective to attain, and then use the table obtained previously to interpolate the value for the weighting factor that corresponds to the target value. This interpolated value for the weighting factor is then inserted into the effective objective function. This effective objective function is optimized, yielding the set of decisions which optimize the primary objective function while at the same time satisfying the constraint that auxiliary objective achieve a target value.
