Publication number: 20070119080Abstract: The present invention provides a battery powered, hand-held signaling device having an illuminated display capable of selectively displaying illuminated indicia including the words “STOP”, “SLOW” and “GO”. The illuminated indicia are preferably color-coded, whereby the word “STOP” is displayed in illuminated red letters, the word “GO” is displayed in illuminated green letters, and the word “SLOW” is illuminated in yellow letters thereby maximizing recognition by an observer, such as the driver of an approaching vehicle. Selection of a particular message to be displayed is accomplished by user actuation of suitable electrical switching circuitry. In alternate embodiments, the device may be adapted for displaying a host of other illuminated messages, such as “TURN RIGHT,” “TURN LEFT,” “PARK,” etc.Type: ApplicationFiled: January 23, 2007Publication date: May 31, 2007Inventor: Eric Spencer

Publication number: 20060223042Abstract: A coaching device and method for providing emergency medical care instructions is shown. The device can include a memory, an audio input, an audio output, a visual display, and a processor. The memory stores a file set made up of multiple question files. The question files include audio data representing a spoken question, at least one valid answer proposed for the question, and visual material. The visual material can be a text version of the question or a valid answer or a visual illustration of the subject matter of the question. Each question file is linked with at least one other question file. A program manages the question files by playing a question, detecting a spoken valid answer to the spoken question, and loading another question file linked to the detected answer. The modular set of interrelated questions provides the rescuer with highly interactive instructions.Type: ApplicationFiled: May 18, 2005Publication date: October 5, 2006Inventors: John Epler, Michael Vanrooyen, Eric Spencer, Ron Elfenbein

Patent number: 6902867Abstract: The invention provides a method for making ink feed vias in semiconductor silicon substrate chips for an ink jet printhead and ink jet printheads containing silicon chips made by the method. The method includes applying a first photoresist material to a first surface side of the chip. The first photoresist material is patterned and developed to define at least one ink via location therein. An etch stop material is applied to a second surface side of the chip. At least one ink via is anisotropically etched with a dry etch process through the thickness of the silicon chip up to the etch stop layer from the first surface side of the chip. As opposed to conventional ink via formation techniques, the method significantly improves the throughput of silicon chip and reduces losses due to chip breakage and cracking. The resulting chips are more reliable for long term printhead use.Type: GrantFiled: October 2, 2002Date of Patent: June 7, 2005Assignee: Lexmark International, Inc.Inventors: Eric Spencer Hall, Shauna Marie Leis, Andrew Lee McNees, James Michael Mrvos, James Harold Powers, Carl Edmond Sullivan
