Abstract: Techniques for controlling a process to prevent injury are presented. The techniques include obtaining a location estimation of a mobile transmitter affixed to an object, where the location estimation is relative to a location of a fixed receiver, and where the obtaining the location estimation includes sending an ultra wideband communication from the mobile transmitter to the fixed receiver and acquiring the ultra wideband communication by a phased antenna array of the fixed receiver; assessing, based on the location estimation, that the mobile transmitter is within an impermissible location; determining that the location estimation is sufficiently accurate based on a distance between the location estimation and the fixed receiver; and interrupting the process upon both assessing that the mobile transmitter is within an impermissible location and determining that the location estimation is sufficiently accurate.

Abstract: A communication system and method include a group of multiple, discrete communication devices, each including an isotropic antenna element and a controller. A role of a first communication device is master device, and the role of the other communication devices is follower device. The controller of the master device determines relative locations of the follower devices to the master device, and assigns different phase delay values to the communication devices based on the relative locations. The controller of the master device communicates message information including the phase delay values, a message payload, and a transmit time to the follower devices for the isotropic antenna elements of the communication devices to collectively form an antenna array that transmits the message payload at the transmit time. The antenna array transmits the message payload with a phase taper defined by the phase delay values to form a beam towards a target.

Abstract: Chip technology for fabricating ultra-low-noise, high-stability optical devices for use in an optical atomic clock system. The proposed chip technology uses diamond material to form stabilized lasers, frequency references, and passive laser cavity structures. By utilizing the exceptional thermal conductivity of diamond and other optical and dielectric properties, a specific temperature range of operation is proposed that allows significant reduction of the total energy required to generate and maintain an ultra-stable laser. In each configuration, the diamond-based chip is cooled by a cryogenic cooler containing liquid nitrogen.

Abstract: Methods, computer systems, and apparatus, including computer programs encoded on computer storage media, for generating and searching reinforcement learning algorithms. In some implementations, a computer-implemented system generates a sequence of candidate reinforcement learning algorithms. Each candidate reinforcement learning algorithm in the sequence is configured to receive an input environment state characterizing a state of an environment and to generate an output that specifies an action to be performed by an agent interacting with the environment. For each candidate reinforcement learning algorithm in the sequence, the system performs a performance evaluation for a set of a plurality of training environments. For each training environment, the system adjusts a set of environment-specific parameters of the candidate reinforcement learning algorithm by performing training of the candidate reinforcement learning algorithm to control a corresponding agent in the training environment.
