Title: Reversible electrochemical mirror for modulation of reflected radiation
Inventor: CUNNINGHAM MICHAEL A
IPC: G02F1/1506
Filed: 1999-08-09
Abstract: An electrochemical mirror includes a transparent first electrode (106) and a second electrode (110). An electrolytic solution (112), disposed between the first and second electrodes, contains ions (116) of a metal which can electrodeposit on the electrodes. A negative electrical potential (118) applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodeposited from the solution onto the first electrode, thereby affecting the reflectivity of the mirror for electromagnetic radiation (122).      A surface modification layer (108) applied to the first electrode ensures that the electrodeposit is substantially uniform, resulting in a mirror layer which increases the reflectivity of the minor. A positive electrical potential (118) applied to the first electrode causes deposited metal to be dissolved form the first electrode and electrodeposited from the solution onto the second electrode, thereby decreasing the reflectivity of the mirror.

Title: Cross-connect matrix task prioritizer
Inventor: MAZZURCO ANTHONY
IPC: H04Q3/68
Filed: 2001-09-27
Abstract: A cross-connect switch (12) uses a matrix (40) for providing connection paths.  The matrix (40) includes prioritization logic (44) for receiving connection requests from restoration state machines (50) (for changing connections responsive to line conditions) and an administrative processor (for changing connections responsive to operator commands). Connection requests from both the restoration state machines (50) and the administrative processor (52) are cached in FIFO memories (54).  When a FIFO memory (54) stores one or more connection requests, the switching control circuitry is notified by a data ready signal. Logic (56) inhibits passing of the data ready signal from the FIFO memory (54) to the switching control (26) until all restoration connection requests have been serviced.

Title: System, system evaluator, and method for validating connection-related communications data collected by a digital switching exchange
Inventor: SCHNEIDER ERNST
IPC: H04M3/32
Filed: 2000-03-02
Abstract: To be able to ensure that a digital switching exchange is able to properly collect data on the charges incurred for pay connections, it is necessary to verify the accuracy of the communications data records generated by the digital switching exchange (20). Existing test systems are merely able to verify the formal structure of the communications data record.     For that reason, the object of the present invention is to make it possible for the communications data record to be validated with greater precision.     For this, the present invention proposes, inter alia, a system containing at least one test unit (40) that is able to be linked to the digital switching exchange (20). The test unit (40) includes a device for generating a connection-related reference data record, whereas the digital switching exchange (20) is able to generate at least one connection-related communications data record from transmitted communications elements. The contents of the connection-related reference data record are compared in a system evaluator (50) to the contents of each connection-related communications data record belonging to it.

Title: In-line sub-surface seeding, fertilizing and watering system
Inventor: LEMPRIERE NOEL D
IPC: A01C23/02
Filed: 2000-05-05
Abstract: An in-line sub-surface seeding, fertilizing and watering system includes a blade (10) mountable into a header member (112) of a parallelogram linkage (110). A pair of parallel rigid drag arms (116, 118) extend between the header member (112) and a hanger member (114) and are pinned at their respective ends so that rotation of the header member relative to the hanger member on the parallel arms maintains a general horizontal orientation of the header member thereby supporting the blade (10) downwardly in a constant orientation. The hanger member is mountable to a supporting frame (182). A selective actuator such as a hydraulic actuator (138) or selectively controllable spring assembly (147) allows selective control of a downward force urging the blade into the soil. Where the selective actuator is a hydraulic actuator (138) mounted between the hanger member (114) or frame and the parallel arms (116, 118) or header member (112), the actuating linkage may be selectively elevated so as to remove the blade (10) from the soil.

Inventor: LIU XINBING
IPC: B23K26/38
Filed: 2000-05-26
Abstract: A diode-pumped, solid-state laser (52) of a laser system (50) provides ultraviolet Gaussian output (54) that is converted by a diffractive optical element (90) into shaped output (94) having a uniform irradiance profile. A  high percentage of the shaped output (94) is focused through an aperture of a mask (98) to provide imaged shaped output (118). The laser system (50) facilitates a method for increasing the throughput of a via drilling process over that available with an analogous clipped Gaussian laser system. This method is particularly advantageous for drilling blind vias (20b) that have better edge, bottom, and taper qualities than those produced by a clipped Gaussian laser system. An alternative laser system (150) employs a pair of beam diverting galvanometer mirrors (152, 154) that directs the Gaussian output around a shaped imaging system (70) that includes a diffractive optical element (90) and a mask (98). Laser system (150) provides a user with the option of using either a Gaussian output or an imaged shaped output (118).
