Patent number: 7442340Abstract: A method and apparatus for sampling for the chemical warfare agent VX, where it is advantageous for the VX to be converted to its G-analog to facilitate aspirator induced movement of the sample through a sample line, to a sampling tube or to sample detection apparatus. A conversion tube assembly has a conversion tube member defining inlet and outlet openings and having a conversion filter therein, which is saturated with an A to G reagent for a chemical warfare agent of interest. The conversion filter assembly includes non-impregnated filter elements and the ends thereof and is retained in position intermediate to the ends of the conversion tube member by retainer elements, which may be tubes or rings. The conversion filter assembly is adapted to be received by a compression fitting or may be directly assembled to a sampling tube or sampling line.Type: GrantFiled: February 18, 2003Date of Patent: October 28, 2008Inventor: Robert Handly

Publication number: 20050180893Abstract: A centerless ground thermal desorption tube comprises an outer barrel and one or more inner spacers insertably positioned within the outer barrel. A suitable sorbent material is positioned within the outer barrel which may be held in place by friction and/or with glass wool plugs, and/or screens, and/or the inner spacers. In one preferred embodiment one glass inner spacer is fused to one end of a glass outer barrel prior to the glass outer barrel being centerless ground to a high precision. The sorbent and/or any wool plugs and/or screens are inserted into a second opposite end of the outer barrel after the centerless grinding process. A second glass is fused to the second end of the glass outer barrel whereby the glass fusing may change the precise tolerance of the centerless ground glass outer barrel at the second end only.Type: ApplicationFiled: February 17, 2004Publication date: August 18, 2005Inventor: Robert Handly

Patent number: 6085350Abstract: An single event upset (SEU) tolerant system for detecting and correcting an SEU includes a decision element (200) for receiving a plurality of outputs (120) from a plurality of signal generators (105) and producing an output (130) therefrom. The decision element includes voters which provide two levels of voting for the plurality of redundant outputs (120). First-level voters (300) provide intermediate voted outputs (315) which are received by a second-level voter to determine an output (130). An output disabler (400) determines when an output is provided external to the decision element. A plurality of comparators (210) receive intermediate voted outputs (315) from first-level voters and compare with a plurality of outputs from a plurality of signal generators to determine upset detected signals (125). An upset detected signal controls the selection of feedback for an element having experienced an SEU.Type: GrantFiled: March 4, 1998Date of Patent: July 4, 2000Assignee: Motorola, Inc.Inventors: Steven Robert Emmert, Paul Robert Handly, Erwin Perry Comer, Jason Jonathon Moore

Patent number: 6020770Abstract: A sequence-controlled digital circuit (21) is presented. The circuit (21) includes a divider (55) and a plurality of transparent latches (51-54) which together form a latch-based sequencer (42). Typically, a clock signal (43) is divided by the divider (55) into an inverted half-clock signal (45) and a non-inverted half-clock signal (44), each enabling alternate latches (51-54) arranged in a cascade. In the cascade, an output of each latch (51-54) drives an input of the following latch (51-54), one such being an inverting output and the rest non-inverting outputs, to form a twisted-loop counter (50). Each output of each latch (51-54) drives a clock input of a flip-flop (61-68), with a serial input signal (46) driving all data inputs, to form a temporal-to-spacial converter (40). Only the divider (55) operates at the rate of the clock signal (43).Type: GrantFiled: May 6, 1998Date of Patent: February 1, 2000Assignee: Motorola, Inc.Inventors: Jan Madsen, Paul Robert Handly, Robert Ivan Foster

Patent number: 5862152Abstract: A JTAG module (12) includes a master component (20) and any number of slave components (22). The master component (20) includes a TAP controller (24) and related control circuits. Through a control bus (35), the TAP controller (24) on the master component (20) controls boundary-scan registers (18) on the slave components (22). The boundary-scan registers (18) in the slave components (22) form a boundary-scan chain that originates and terminates at the master component (20). TAP controller circuitry may be omitted from the slave components (22). The boundary-scan registers (18) on the master and slave components (20, 22) are partitioned into external sections (26, 34) and internal sections (28, 36). The external sections couple to conductive traces (46) which are accessible from outside the module (12). The internal sections couple to conductive traces (48) which are substantially inaccessible from outside the module (12).Type: GrantFiled: November 13, 1995Date of Patent: January 19, 1999Assignee: Motorola, Inc.Inventors: Paul Robert Handly, Brian Lee Deitrich, Robert Francis Yockey

Patent number: 5397410Abstract: A method for making machine readable bar code markings (20) on glassware (10) is disclosed. A ceramic film (16B) first has bar code markings (20) placed thereon. The ceramic film with the bar code markings (20) is placed on the outer surface (14) of the glassware (10). The ceramic film (16) and glassware (10) are heated or fired for a predetermined time period at a temperature over 1100.degree. F. adequate to effect fusing of the film (16B) onto the glassware (10) while providing a fused layer (18) therebetween.Type: GrantFiled: March 22, 1993Date of Patent: March 14, 1995Inventor: Robert A.
