Abstract: A crafting apparatus (10) includes a working portion (22) and a base portion (20). The working portion (22) includes a lower surface (32) and an upper surface (34). The upper surface (34) defines a working three dimensional Cartesian coordinate system (X-Y-Z). The base portion (20) includes a lower surface (24) and an upper surface (26). The lower surface (32) of the working portion (22) is disposed adjacent to the upper surface (26) of the base portion (20). The lower surface (24) defines a non-working three dimensional Cartesian coordinate system (XS-YS-ZS). The upper surface (34) of the working portion (22) extends relative to the lower surface (24) of the base portion (20) at an angle (?22) for angularly-offsetting the working three dimensional Cartesian coordinate system (X-Y-Z) from the non-working three dimensional Cartesian coordinate system (XS-YS-ZS). Methods (200, 300) are also disclosed.

Abstract: Various embodiments of an interface control subsystem may be used between an electrode terminal and a recording terminal of a neurostimulation and neurorecording system. The interface control subsystem may operate in three modes. In a disable mode, a first transistor and a second transistor disposed between the electrode terminal and the recording terminal may operate in a cutoff region and generate a high impedance. In an active mode, the first transistor and the second transistor may operate in a saturation region and generate a low impedance. In a stimulation mode, the first transistor and the second transistor operate in a triode region and generate an impedance between the high impedance of the disable mode and the low impedance of the active mode. The interface control subsystem may further limit voltage at the recording terminal in response to a detected overvoltage condition.

Abstract: A system and method for determining positions in three-dimensional space are described. The system includes a controller, a phase image module, a presentation module and a phase determination module. The controller receives projector geometry parameters. A phase image module determines a plurality of sinusoidal images where a constant phase represents a flat plane in a three-dimensional space based on the projector geometry parameters.

A synchronized time-stamped matching strategy is applied to achieve high performance in detecting the screens playing motion intensive video contents and an aggressive feature selection method is applied to minimize the system uploading bandwidth. The system can accurately find display screens playing either static or dynamic content within an image captured on a mobile device.
