Publication number: 20110174953Abstract: EZ-Mark Picture Hanging Marker consists of a head that has an adhesive coating on one side and a marking device, like a pin or marker on the other side. On the other side of the marking device is an encasement sleeve that protrudes further than the marker. The adhesive coating of the head is attached to the back of a picture frame or other object that needs hanging. Once the adhesive coating or other attachment mechanism is put in place, the frame may be moved along the wall into the desired location of hanging. The EZ-Hang Picture Hanging Marker user is then able to mark the desired location of where they would like to place their nail by pressing on the picture frame or hanging instrument. Only when significant force is applied to the picture frame, does a marking device protrude from EZ-Hang's encasement sleeve and mark the wall.Type: ApplicationFiled: January 19, 2010Publication date: July 21, 2011Inventors: Michael David Ruiz, Graig Jerove Lenz

Publication number: 20100329274Abstract: A network repeater is configured to repeat data packets in a broadcast mode without generating a significant broadcast storm. The network repeater is configured to detect a characteristic of a received data packet. The data packet characteristic is compared with valid copies of packet characteristics previously stored in a packet registry. During a delay period, if a valid copy of the detected characteristic is found in the packet registry, then it is assumed that the packet is being received for the second time and the data packet is not repeated in the broadcast mode. If a valid copy of the detected characteristic of the data packet is not found in the packet registry, then the characteristic is stored in the packet registry and the data packet is repeated in a broadcast mode.Type: ApplicationFiled: September 2, 2010Publication date: December 30, 2010Inventors: Veronica Romero, David Ruiz

Patent number: 7507972Abstract: A compact ionization source includes first and second electrodes, each having a plurality of fingers that are interdigitated with each other. The spacing between the first and second electrode, preferably less than 1 mm, creates a large electric field when a potential is applied across the first and second electrodes. The large electric field creates an ionization volume between the fingers of the first and second electrode and ionizes a portion of the molecules occupying the ionization volume. The interdigitated fingers of the first and second electrodes allow for a narrow gap separating the electrodes while presenting a large flow area for ionizing molecules for downstream analysis.Type: GrantFiled: October 10, 2005Date of Patent: March 24, 2009Assignee: Owlstone Nanotech, Inc.Inventors: Martyn Rush, Paul Boyle, David Ruiz-Alonso, Andrew Koehl, Russell Parris, Ashley Wilks
