Abstract: A three-dimensional perforated-panel wall mounting system comprises multiple perforated panels mounted in a three-dimensional configuration, which increases the panel storage area for a corresponding two-dimensional mounting surface area. For example, perforated panels are attached to two sides of a triangular-shaped mounting bracket. When the third side of the mounting bracket is attached to a wall or other mounting surface, the system provides twice the perforated panel area compared to a surface area of the wall covered by the system.

Abstract: An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

Abstract: An interface in accordance with present embodiments includes a base and a theme portion disposed on the base. A first layer is disposed on the base and includes a mixture with metallic powder suspended within a translucent medium. A second layer is disposed on the base over the first layer and over the theme portion, and includes the mixture. A third layer is disposed on the base and on the theme portion over only portions of the second layer. The third layer includes paint and paint thinner. A fourth layer is disposed on the theme portion over the third layer and exposed portions of the second layer. The fourth layer also includes the mixture.

Abstract: The invention relates to an electrostatic holder comprising: a body, and a clamping element attached to the body, said clamping element comprising an electrode for applying an attractive force between the clamping element and a first to be clamped object, wherein an outer edge of the body is configured to provide a gap between the outer edge of the body and the first to be clamped object, which gap is configured for outputting a fluid for reducing dust particles reaching the first to be clamped object or a second to be clamped object on an opposite side of the holder.

Abstract: Methods for forming a unitized crucible assembly for holding a melt of silicon for forming a silicon ingot are disclosed. In some embodiments, the methods involve a porous crucible mold having a channel network with a bottom channel, an outer sidewall channel that extends from the bottom channel, and a central weir channel that extends from the bottom channel. A slip slurry may be added to the channel network and the liquid carrier of the slip slurry may be drawn into the mold. The resulting green body may be sintered to form the crucible assembly.

Abstract: The technology described herein identifies and mitigates phishing attempts by analyzing user input received at the operating system level. Initially, a credential, such as a username or password, is registered with the threat detection system. The technology described herein intercepts user input at the operating system level, generates a hash of the input, and compares it with a hash of a credential being monitored. A credential entry is detected when a hash for the character string entered matches a hash for a credential being monitored. The technology described herein will perform a threat assessment when a secret entry is detected. The threat assessment may use the application context and the network context as inputs to the assessment. Various mitigation actions may be taken when a threat is detected.

Abstract: A display fitting lock mechanism for a mannequin is provided to removably attach a mannequin part to another mannequin. The lock mechanism includes a shaft member having a shaft body including a recess. The lock mechanism also includes a receiving portion having a straight tube. The straight tube includes an interior channel extending through a longitudinal length of the straight tube that is configured to receive the shaft body of the shaft member. The lock mechanism further includes a locking clamp attached to the straight tube. The locking clamp having a locking tooth that is configured to extend into the recess in the shaft body when the locking clamp is in a locked position.

Abstract: A master controller device includes a control gripper to control at least the open/close degree of freedom of a slave surgical instrument. The control gripper has a first interface portion and a second interface portion for the fingers of a user, wherein the first interface portion is opposite to the second interface portion. Each interface portion includes a cavity thereof formed by a respective conically-developing surface. The controller device can further include a handle which forms the handle of the master controller device, wherein the handle has a body which forms at least one seat with a surface thereof to rest on the back of a user's hand.

Abstract: Disclosed herein are systems and methods for using machine learning for geographic analysis of access attempts. In an embodiment, a trained machine-learning model classifies source IP addresses of login attempts to a system as either blacklisted or allowed based on a set of aggregated features that correspond to login attempts to the system from the source IP addresses. The set of aggregated features includes, in association with each respective source IP address, a geographical login-attempt failure rate of login attempts to the system from each of one or more geographical areas that each correspond to the respective source IP address. Source IP addresses that are classified by the machine-learning model as blacklisted are added to a system blacklist, such that the system will disallow login attempts from such source IP addresses.
