Publication number: 20180172852Abstract: A versatile radiation detector comprises an extremely thin scintillator which is optically coupled to a different, much thicker scintillator that produces light pulses detectably different from the thin scintillator. Proximate to the thin scintillator is an extremely thin converter layer comprising boron or lithium. Neutron reactions in the converter generate ions that are detected in the thin scintillator, whereas gamma rays interact with the thick scintillator. Both scintillator light pulses travel through the thick scintillator as a light guide, and are detected in a light sensor. Numerous versions are disclosed for different applications, including gamma-blind, hydrogen-free, and multiple stacked configurations. The detector is economical and versatile, very well-suited for large-area inspection applications, highly effective in walk-through portal applications, and optimal for hand-held survey instrument products.Type: ApplicationFiled: March 17, 2017Publication date: June 21, 2018Inventor: David Edward Newman

Patent number: 9864074Abstract: A device that detects gamma rays or neutrons, and determines their source location, comprises two scintillator panels separated by a shield barrier. Particles incident from one side can fully strike the first scintillator, but are blocked by the shield from reaching the second scintillator. Particles from the other side can reach only the second scintillator. Thus the detector indicates the left-right direction for the source location quickly, and then with further data localizes the source precisely by analysis of the two opposite scintillator count rates versus angle, using methods disclosed. The detector enables rapid inspections of vehicles and cargo containers for clandestine radiological and nuclear weapons, and sensitive localization of radioactive material in a walk-through portal application. Detectors with such capabilities are essential for stopping nuclear and radiological terrorism.Type: GrantFiled: May 15, 2017Date of Patent: January 9, 2018Inventor: David Edward Newman

Patent number: 9202463Abstract: A method is disclosed for generating a voice-activated responsive action, such as a pulse or a measurement, with improved speed and time resolution. First, an operator calls an arming command to prepare the application, and then calls a trigger command to initiate the responsive action. The responsive action is generated immediately upon detecting the leading edge of the trigger command, resulting in an extremely fast response with precise timing. The particular responsive action may be determined by the type of sound detected, or by other information contained in the trigger command, or by the arming command, or by another prior command. Other types of preparatory events are disclosed. Efficient methods for identifying commands are disclosed. For all applications requiring an extremely prompt, precisely timed, hands-free response to a voice command, this invention is enabling.Type: GrantFiled: April 1, 2013Date of Patent: December 1, 2015Assignee: ZANAVOXInventor: David Edward Newman

Patent number: 8990079Abstract: When a voice-activated device or application is first started, the signal levels corresponding to spoken commands are initially unknown, making it difficult to set detection thresholds. The inventive method provides an initial command-detection threshold based on the noise level alone. The first command is detected using this initial threshold. Then the threshold is revised according to the first command sound, and a second command is detected using the revised threshold. After detecting each command, the detection threshold is further refined according to the current noise and command sounds. Methods are also disclosed for optimizing the thresholds, adjusting parameters according to sound, and detecting voiced and unvoiced sounds separately. These capabilities enable many emerging voice-activated products and applications.Type: GrantFiled: September 17, 2014Date of Patent: March 24, 2015Assignee: ZanavoxInventor: David Edward Newman

Patent number: 8954334Abstract: A voice-activated pulser can trigger an oscilloscope or a meter, upon a simple voice command, thereby enabling hands-free signal measurements. The pulser can also be used to control the circuit under test, activating it or changing parameters, all under voice control. The pulser includes numerous switch-selectable output modes that allow users to generate complex, tightly-controlled diagnostic sequences, all activated upon a voice command and hands-free. The invention includes a fast, robust command-interpretation protocol that completely eliminates the expense and complexity of word recognition. Visual indicators display the device status and various operating modes, and also confirm each output pulse. The device receives voice commands directly through an internal microphone, or through a detachable headset, and confirms each command with an acoustical signal in the headset.Type: GrantFiled: October 15, 2011Date of Patent: February 10, 2015Assignee: ZanavoxInventor: David Edward Newman

Patent number: 8924209Abstract: A method is disclosed for identifying a spoken command by detecting intervals of voiced and unvoiced sound, and then comparing the order of voiced and unvoiced sounds to a set of templates. Each template represents one of the predetermined acceptable commands of the application, and is associated with a predetermined action. When the order of voiced and unvoiced intervals in the spoken command matches the order in one of the templates, the associated action is thus selected. Silent intervals in the command may also be included for enhanced recognition. Efficient protocols are disclosed for discriminating voiced and unvoiced sounds, and for detecting the beginning and ending of each sound interval in the command, and for comparing the command sequence to the templates. In a sparse-command application, this method provides fast and robust recognition, and can be implemented with low-cost hardware and extremely minimal software.Type: GrantFiled: September 12, 2012Date of Patent: December 30, 2014Assignee: ZanavoxInventor: David Edward Newman

Patent number: 8781821Abstract: A method is disclosed for controlling a voice-activated device by interpreting a spoken command as a series of voiced and non-voiced intervals. A responsive action is then performed according to the number of voiced intervals in the command. The method is well-suited to applications having a small number of specific voice-activated response functions. Applications using the inventive method offer numerous advantages over traditional speech recognition systems including speaker universality, language independence, no training or calibration needed, implementation with simple microcontrollers, and extremely low cost. For time-critical applications such as pulsers and measurement devices, where fast reaction is crucial to catch a transient event, the method provides near-instantaneous command response, yet versatile voice control.Type: GrantFiled: April 30, 2012Date of Patent: July 15, 2014Assignee: ZanavoxInventor: David Edward Newman
