System and method for enabling robot to perceive and detect socially interacting groups
This disclosure relates to system and method for enabling a robot to perceive and detect socially interacting groups. Various known systems have limited accuracy due to prevalent rule-driven methods.

Simulation method of an electron device
There is a significant precaution when performing random dopant fluctuation by using the drift-diffusion model that is the basis of the conventional device simulation. Because the continuation by a long wavelength approximation was done to derive said drift-diffusion model. That is how to recover the location dependence of discrete impurity ions in the long wavelength approximation. For example, in the case that there is an impurity ion near to the interface to an insulating film, the charge density of an impurity ion, which was made continuous in the conventional method, is unable to catch the charge density change due to polarization at the interface. Because this polarization is dependent of the location of a discrete impurity ion near to the interface.A method for simply implementing the effect of polarization to the device simulation is provided by appending an image charge inside the insulating film to linearize the charge of discrete impurity ion which locates near to the interface to satisfy the consistency to the drift-diffusion model while keeping the location dependency of the discrete ion. |

Method of processing incoming signals received at spatially-separated receivers
A method of processing incoming signals, such as RF signals, includes receiving the incoming RF signals at two (or more) spatially-separated receivers, then processing the signals to determine a phase lag between the two signals. This allows a presumed location of the signal source to be determined, based on the time difference of arrival (TDOA) of signals at the separated receivers. This can be used to produce a phase adjustment of one of the signals, allowing the signals to be coherently summed. The coherently summed combined signal is then examined for instances where a threshold magnitude is exceeded. This information is then used to create a blanking mask, which is then employed as a filter to incoming signals, to blank out non-coherent signals, such as noise and extraneous signals from sources that are not of interest. The blanked signal train is then examined/analyzed for constant pulse repetitions. |

Register assembly
In one embodiment, the invention is a register assembly for inserting into floors, ceilings and walls, comprising a first open top box having a bottom surface, which defines a centrally disposed opening through which air flows from a first environment to a second environment. A support is disposed within the first open top box. A second open top box nests within the first open top box, and is supported by the support. A restraint is associated with the first and second box to restrain the second box within the first box. The first and second open top boxes are sized and dimensioned to be coplanar with each other when nested. A conduit is also defined between the first open top box bottom surface opening and the second open top box to flow air from the first environment to the second environment. |

Electric oven with a closed-door broiling operation
A method of operating an electric oven includes generating a door-closed signal if the oven door is in a closed position. The electric broiling element is activated to perform a closed-door broil operation in response to generation of the door-closed signal. The temperature within the cooking chamber of the electric oven is determined during the closed-door broil operation and the electric broiling element is deactivated if the temperature within the cooking chamber exceeds a shutoff temperature. |
