Abstract: Some aspects are directed to an all-on-chip, optoelectronic device for sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions. This solid-state integrated detector uses optical-field-driven electron emission from resonant nanoantennas to achieve petahertz-level switching speeds by generating on-chip attosecond electron burst. Also disclosed is a cross-correlation technique based on perturbation of local electron field emission rates that allows for the full characterization of arbitrary electric fields down to 1 femtojoule, and/or on the order of 500 kV/m, using plasmonic nanoantennas.

Abstract: A system and method for dynamically checking clearance within a geometric mesh model includes a user computer system having a remotely located computer system, and a data storage device. The method periodically updates a digital model of assembled component parts stored on the data storage device, interactively selects a predetermined clearance rule applicable to the digital model and interactively selects a predetermined clearance condition applicable to the selected clearance rule for the digital model that modifies the predetermined clearance rule. The method periodically calculates clearance within the assembled digital model using the selected clearance rule and the selected clearance condition and summarizing the clearance check. The clearance check summary identifies a clearance issue using a predetermined clearance checking criteria and submits the identified clearance issue to an issue manager software program for tracking clearance issues.

Abstract: A system and method for dynamically checking clearance within a geometric mesh model is provided. The system includes a user computer system having memory, a processor, a user input device and a display device and a remotely located computer system having a processor and a memory and operatively in communication with the user computer system. The system also includes a data storage means operatively in communication with the remotely located computer system and the user computer system for storing information. The method includes the steps of periodically updating a model representing a digital buck of assembled component parts that is digital buck is stored on the data storage means, interactively selecting a predetermined clearance rule applicable to the digital buck and interactively selecting a predetermined clearance condition applicable to the selected clearance rule for the digital buck that modifies the predetermined clearance rule.

Abstract: A method and apparatus implements a novel surround sound panning paradigm. Rather than controlling the x-y position of a perceived sound source within a linear grid, the perceived sound is characterized by specifying perceived arrival energy as a function of direction of arrival. In one embodiment, perceived sound source azimuth and width (or spatial extent) are specified, which parameters are used in a novel panning law to control each output channel. In a preferred implementation, the panning control is provided in a Plug-In application for a conventional DAW environment such as Pro Tools, which application includes an interface that provides precise control over the direction and spatial extent of audio.
