Abstract: Hinged safety gates and methods for controlling access to an elevated work surface are disclosed. The hinged safety gate can include a gate frame and a retainer assembly. The gate frame can have a distal upright member, an upper cross-arm, and a lower cross-arm. The upper cross-arm can have an upper cross-arm height (or vertical dimension), and the lower cross-arm can have a lower cross-arm height. The hinged safety gate can have a retainer assembly that is configured to be attached to a proximal end of the gate frame and to hingedly couple the gate frame to a stationary vertical surface, permitting the gate frame to swing between an open and a closed position. Some embodiments satisfy various spatial safety requirements with only two cross-arms. Some embodiments are horizontally adjustable in two different manners to accommodate a range of access area widths.

Abstract: The online concierge system generates task units based on orders and assigns batches of task units to pickers. The online concierge system generates task units based on received orders. The online concierge system generates permutations of these task units to generate candidate sets of task batches. The online concierge system scores each of these candidate sets, and selects a set of task batches to assign to pickers based on the scores. Additionally, to determine which task UI to display to the picker, the picker client device uses a UI state machine. The UI state machine is a state machine where each state corresponds to a task UI to display on the picker client device. The state transitions between the UI states of the UI state machine indicate which UI state to transition to from a current UI state based on the next task unit in the received task batch.

Abstract: A hinged safety gate can include a gate frame and a retainer assembly. The gate frame can have a distal upright member, an upper cross-arm, and a lower cross-arm. The hinged safety gate can have a retainer assembly that is configured to be attached to a proximal end of the gate frame and to hingedly couple the gate frame to a stationary vertical surface, permitting the gate frame to swing between an open position and a closed position. The gate frame is horizontally adjustable in two different manners relative to the retainer assembly to accommodate a range of access area widths.

Abstract: Systems and methods provide for an intelligent laboratory lockbox. The intelligent laboratory lockbox self-regulates an internal temperature of one or more compartments, regardless of external temperatures. The one or more compartments can be individually climate controlled. The intelligent laboratory lockbox is in communication with a remote server, which is in communication with one or more remote sources including an electronic health record server, a courier server, and the like.

Abstract: A method for developing or improving a process for producing a product from a material comprising steps of acquiring the composition for at least two slurries as raw material data (17) for the CMP based manufacturing process and its relevant parameters (2) by using a Data Collecting computer (9); physically performing specific method steps of a CMP process; measuring relevant parameters of the used slurries and the physically performed CMP process to determine the CMP process performance by using the Data Collecting computer (9); analyzing the measured data about the relevant parameters with a specific software performed on an Analyzing computer (11) by creating for the software and applying with it a predictive model using Machine Learning to understand the intercorrelation of the different parameters and using the results to improve the CMP process performance and the resulting product quality of the CMP based manufacturing process.

Abstract: A pedestrian door system includes a door frame comprising a frame strike side, a frame hinge side, and a frame sealing surface that extends up each of the frame strike and frame hinge sides. A threshold extends between the frame strike and frame hinge sides and includes a base secured to a floor surface and a threshold sealing surface. A door panel includes a panel bottom side, a panel strike side, a panel hinge side, and a continuous gasket extending continuously along the panel bottom side and up each of the panel strike and panel hinge sides. A door hinge couples the panel hinge side to the frame hinge side and facilitates hinged movement of the door panel between an open position and a closed position in which the gasket seals against the frame sealing surface and the threshold sealing surface in a liquid-tight manner.

Abstract: Apparatus and methods for assembling, installing, and operating a manually operated gate (e.g., a safety gate) are provided. The manually operated safety gate can include a gate frame and a spring assembly. The gate frame can include a proximal upright member, a distal upright member, an upper arm, and a lower arm. The proximal upright member can be anchored to a stationary surface. The upper arm and lower arm can be pivotably coupled to the proximal upright member and distal upright member to form a parallelogram. The manually operated gate can be configured to pivot between an open position and a closed position at a constant angular velocity. The gate can freely pivot to the closed position from a self-close position. A kit can contain the required structural components and instructions and can be used to assemble the manually operated gate assembly.

Abstract: Self-closing safety gate embodiments are disclosed herein. The self-closing safety gates include a hinge plate configured to rotate about a vertical support member and engage a hoop portion. In some embodiments, the hinge plate includes at least one support arm portion with a channel. In such embodiments, the channel can be configured to receive and frictionally engage a hoop arm of the hoop portion with a compressive fastener. In some embodiments, the self-closing safety gate can be damped.

Abstract: Methods for the treatment of lung injury caused by chemical inhalation, smoke inhalation or microbial infection are described. The methods include administering a therapeutically effective amount of nitrite or a nitrite formulation. Nitrite formulations that include a nitrite salt and an anti-caking agent, such as sodium bicarbonate, and the use of such formulations, is also described.
