Disclosed are certain 3-phenoxypyridazines, compositions thereof which are herbicidal and methods of using such compositions for controlling undesired plants. Intermediate compounds useful in preparing the phenoxypyridazines are also disclosed.

A hierarchical testing method is implemented taking advantage of the nature of the most common defects in an LCD panel to achieve fast effective parametric testing of LCD panels and the like. At the first hierarchy of testing, the panel is logically divided into zones and each zone tested in isolation to identify zones having at least one defect. At the next hierarchy, electro-optic assisted zone inspection is performed to identify where within the zone the defects are located. Lastly, every pixel is inspected using a voltage imaging method to determine whether the switching integrity of the pixel is acceptable. The testing apparatus includes a plurality of panel interface devices coupling the panel under test's drive lines and gate lines to a precision measurement unit (PMU). A controller determines the PMU signals and configures the panel interface devices. The PMU monitors select drive lines and gate lines to isolate zones having defects. An electro-optic voltage measurement system is used to identify the location of defects within an isolated zone.

An electrosurgical device having an electrode with a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. An elongated hollow body has an internal cavity, a front end, a rear end, an external surface. An electrical circuit is arranged within the body. The second portion of the electrode is not surrounded by the hollow body. A first button is arranged on the external surface of the body for controlling a current flow at a first level. A vacuum tube is slidably engaged by the body. A vacuum outlet port is arranged near the rear end, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.

A content matching engine (CME) uses a content addressable memory (CAM) array that stores a plurality of strings in separate entries. The strings define one or more rules to be matched. The strings of each rule are linked, thereby providing a required order. The strings of each rule can be linked by per-entry counters associated with each string, or by a state machine. The strings in the CAM array are compared with a packet, which is shifted one symbol at a time (because the strings can start on any boundary). When the CAM detects a match, the CAM skips over the string that resulted in the match, thereby preventing erroneous matches. The CAM allows parallel matching to be performed for multiple rules. If the contents of a packet match all of the strings of a rule, in order, then the CME asserts a match/index signal that identifies the matched rule.

A method for dynamic scheduling of data transmission for a large number of data channels under the available bit rate (ABR) service protocols of asynchronous transfer mode (ATM) uses a schedule table and ready queue. In this method, at each time slot, data channels referenced in the current entry of the schedule table is removed from the schedule table and appended to the ready queue. At each available transmission time slot, an ATM cell is transmitted from the data channel referenced in the record at the head of the ready queue. The data channel is then rescheduled for in the schedule table for the next transmission. The present invention also accommodates data transmission rates related to fractional time slot intervals.

A method of programming a cache tag comparator by designing a semiconductor device's internal circuitry such that an input/output pin of the device may be programmed by an external resistor to ground that will indicate during the reset phase of the device that an alternate function for the pin is to be selected or that the pin itself is to be disabled.

A method and system for deploying content to devices is provided. The method and system can be used to deploy markup content to web browser applications on wireless devices. The wireless devices may included, for example, WAP phones, HDML phones, Palm VII, Palm V, etc. The method and system can also be used in conjunction with wired systems. A translator receives data, in a variety of formats, from the wireless devices. The translator then translates the data into a standardized format. A content provider interface receives the data in the standardized format and provides content data, also in the standardized format. The content data in the standardized format is provided to a transformer. The transformer transforms the content data into the pre-selected format for the particular wireless device. The content data can then be utilized and manipulated by the wireless device.

A method for producing antibodies and plant protein toxins in plant cells is described which includes the steps of providing a genetic construct to encode the secretable protein, delivering copies of the construct into a liquid suspension culture of tobacco cells, selecting for cells that have acquired the genetic construct, and allowing the desired protein to accumulate in the liquid media in which the plant cells are grown, and isolating the desired protein away from the tobacco cells.

A method is disclosed for recovering cobalt, which comprises adding ammonia to a cobalt chloride solution to a pH of from about 8.8 to about 9.6 with oxidation, to form hexammine cobalt (III) chloride, adding to the resulting solution of hexammine cobalt (III) chloride, sodium chloride in an amount sufficient to result in the precipitation of at least about 98% by weight of the cobalt as cobalt hexammine (III) chloride at a temperature of no greater than about 40.degree. C., separating the precipitate of cobalt hexammine (III) chloride from the resulting mother liquor which contains the balance of the cobalt, adding to the mother liquor, aluminum powder in an amount sufficient to result in the precipitation of the balance of the cobalt as cobalt metal, and separating the cobalt metal from the resulting spent liquor.
