Abstract: A method and system for transmission of digital content via e-mail with point of use digital rights management is disclosed. The secured access rights to the digital content may be customized for individual recipients by the sender, and may evolve over time. The access rights are enforced according to a time-dependent scheme. A key server is used to arbitrate session keys for the encrypted content, eliminating the requirement to exchange public keys prior to transmission of the digital content. During the entire process of transmitting and receiving e-mail messages and documents, the exchange of cryptographic keys remains totally transparent to the users of the system. Additionally, electronic documents may be digitally signed with authentication of the signature.

Abstract: An integrated compressor comprises an electric motor that is prone to high temperatures. In a first cooling feature, axial and/or radial cooling channels are provided through the stator of the motor to supply coolant to portions of the stator that are prone to high temperatures. In a second cooling feature, jets are used to spray coolant towards the end-windings of the motor, to thereby cool the end-windings.

Abstract: Traditionally, integrated motor compressors utilize a radial penetrator that is connected to the motor stator via terminals and wires. This radial connection requires the motor stator to be installed within the compressor housing prior to the connection. In addition, the wires are subject to failure from rapid gas decompression. Accordingly, an axial penetrator is disclosed to provide a conductive path, through the housing, parallel to the longitudinal axis of an integrated motor machine (e.g., integrated motor compressor). This enables the connection to be performed prior to installation of the motor stator within the housing. This also enables the conductive path between the motor windings and axial penetrator to be formed, as a single integrated path, using the same conductive and insulative materials. In turn, this ensures that the entire conductive path behaves the same during decompression, reduces costs, simplifies the installation process, and increases the robustness of the connection.

Abstract: A method is described. The method comprises obtaining a recording of one or more physical interactions performed in relation to one or more physical components, in a simulation environment, playing back the recording such that the one or more physical interactions are represented in the simulation environment, and in the simulation environment, detecting a user interaction with one or more physical components of the simulation environment. The method further comprises determining whether the user interaction is congruent with at least one corresponding physical interaction of the one or more physical interactions in the recording, and in response to such congruence, continuing playback of the recording in the simulation environment.

Abstract: An integrated compressor comprises an electric motor that is prone to windage losses, radial loads, and recirculation flows. According to a first feature, partial grooves or riblets may be formed on the surface of a motor stator that defines the radially outward boundary of the air gap between the motor stator and the motor rotor. These partial grooves or riblets may maintain low to moderate windage losses, while reducing radial loads in the motor. According to a second feature, a support structure may be designed with a nose portion that is configured to disrupt or otherwise reduce recirculation flows within the end-winding cavity housing the end-winding of the motor. According to a third feature, the spiral orientation of the top coil of the end-winding may be aligned with the rotation direction of the motor rotor to reduce recirculation flows within the end-winding cavity.

Abstract: Example fume extractors provide improved fume at the point of fume generation extraction for welding torches. In some examples, a fume extractor attachment is mounted onto the welding torch (e.g., a metal inert gas (MIG)), in which the fume extractor attachment enables fume extraction at a location adjacent to a nozzle of the welding torch, which captures and channels fumes for collection and filtering. Example fume extractor attachments enable an operator to modify a variety of torches to easily add fume source capture capabilities to a standard welding torch, thereby providing improved fume extraction efficiency by locating the fume extraction closer to the welding arc.

Abstract: Tumor-derived cell-free DNA from the aqueous humor is assayed for diagnosis, and therapeutic prognosis of retinoblastoma demonstrating eyes with a more aggressive phenotype (with the presence of gain of 6p) and those that have a higher likelihood of responding to therapy. This also allows for evaluation of tumor response to therapy and a marker of recurrent or residual disease that requires further therapy. This method avoids direct biopsy of retinoblastoma, which is contraindicated due to risk of extraocular tumor dissemination. Somatic chromosomal copy number alterations of tumor-derived cell-free DNA provides significant prognostic value; the presence of gain of 6p was associated with a 10× increased risk of a tumor NOT responding to chemotherapy with local consolidation and requiring enucleation to cure the child of disease. AH testing also provides accurate indicators of progression of retinoblastoma and its response to therapy over the course of treatment.

Abstract: Examples provide a fruit ripening rack having a plurality of chambers for on-site produce ripening at a retail location. A controller component generates predicted demand for ripened fruit on a selected date at a selected location based on transaction history data and/or seasonal demand. The controller component calculates the quantity of fruit based on the predicted demand. The controller component determines conditions within each chamber to accelerate ripening of the calculated quantity of one or more types of fruit to one or more selected levels of ripeness on the selected date. The conditions include amount of ethylene gas in each chamber, length of exposure to the ethylene gas, temperature inside the chamber and/or humidity level inside the chamber. The fruit ripening rack controls internal conditions within each chamber to provide variable fruit ripening in accordance with per-chamber configurations to satisfy predicted daily demand at the selected location.

The system determines respective indicated geographic locations of a plurality of delivery agent devices associated with a plurality of delivery agents. Based at least on the first computational model predicting that a first merchant of the individual merchants is predicted to receive an order for the upcoming time period, delivery agent management logic is executed to receive the current locations of the active delivery agents and select a delivery agent to move to a location to be in position for picking up the order that is predicted to be received by the first merchant. The system sends a message to the delivery agent device of the selected delivery agent to instruct the selected delivery agent to move to the location.

Abstract: Examples provide a system for cold-chain compliant item selection. A set of perishable items are selected for retrieval by a user based on item data, cold-chain compliance score(s), and/or cold-chain compliance restrictions associated with each user. The selected set of items are assigned to the user for retrieval in accordance with a set of cold-chain compliance parameters, including a per-item maximum dwell-time specifying a maximum time interval between removal of a perishable item from a temperature-controlled display area and receipt of the perishable item at an intake area. A dwell-time is calculated for an item received at an intake area. The item is accepted if the per-item maximum dwell-time exceeds the calculated dwell-time and the item is rejected if the calculated dwell-time exceeds the per-item maximum dwell-time. An incentive is provided to the identified user based on a cold-chain compliance score for the user.
