Abstract: A real time assay monitoring system and method can be used to monitor reagent volume in assays for fluid replenishment control, monitor assays in real-time to obtain quality control information, monitor assays in real-time during development to detect saturation levels that can be used to shorten assay time, and provide assay results before the assay is complete, enabling reflex testing to begin automatically. The monitoring system can include a real time imaging system with a camera and lights to capture images of the assay. The captured images can then be used to monitor and control the quality of the staining process in an assay, provide early assay results, and/or to measure the on-site reagent volume within the assay.

Abstract: A media presentation and distribution system includes a verification server that handles dynamic verification of playback of media assets on a client device. The client device generates support information for a media asset based on an associated asset identifier that is detected during a playback of the media asset on a client device. The client device further encrypts the support information for the media asset based on a client private key associated with the client device and an asset public key for the media asset. The playback of the media asset on the client device is verified based on a verification message, the support information, an encrypted verification message, and the associated asset identifier. A defined asset delivery criteria is satisfied and a deviation or an error with the playback of the media asset is identified based on the verification of the playback of the media asset.

Abstract: A method and system enhances the execution of the telemedicine impairment repair process (IRP) to claim closure by assisting all stakeholders by monitoring the process and reminding the stakeholders of the stakeholder roles and responsibilities to maintain a prudent time frame for the reported injury and/or illness. The method of and system for executing an impairment repair process addresses flaws in the current process by implementing timing guided by legislation and best medical practice. Key aspects of the impairment repair process are addressed to ensure prudent timing by assuring accuracy of claim development, monitoring, and initiating communication to closure. The process is implemented in multiple stages including, assessment, documentation, prescribed treatment, and analysis of outcome.

Abstract: A vapor-compression multi-evaporator cooling system comprises a cooling control system and two or more evaporators each coupled to an expansion valve. Each evaporator is selectively enabled or disabled during operation. When an evaporator is enabled, the evaporator transfers heat into a working fluid within the system. When an evaporator is disabled, the evaporator does not exchange any appreciable amount of heat within the system. The cooling control system includes a cooling controller, an adjustable compressor, a condenser, and a variable speed fan that provides selectable amounts of cooling to the condenser. During operation, the cooling controller adjusts the compressor operation and fan speed to maintain stable operation of the cooling system. To compensate for enabling or disabling of evaporators, the cooling controller adjusts compressor operation and fan speed to provide more or less compression and more or less condenser cooling to maintain stable and efficient operation of the cooling system.

Abstract: A catheter organizer for organizing one or more catheters during a surgical procedure includes a drape and a plurality of clips tethered to the drape in an arrayed pattern. The clips are arranged to receive the one or more catheters such that the catheters move longitudinally and rotate within said each clip. Each clips has movable members for reversibly changing the clip from an open configuration to a closed configuration by manipulation of the movable members.

Abstract: The present specification discloses a high speed scanning system for scanning cargo carried by rail. The system uses of a two-dimensional X-ray sensor array with, in one embodiment, a cone-beam X-ray geometry. The pulse rate of X-ray source is modulated based on the speed of the moving cargo to allow a distance travelled by the cargo between X-ray pulses to be equal to the width of the detector, for a single energy source, and to half the width of the detector for a dual energy source. This ensures precise timing between the X-ray exposure and the speed of the passing object, and thus accurate scanning of cargo even at high speeds.

Abstract: A trapdoor rejection subsystem includes one or more trapdoor rejection mechanisms. Each trapdoor rejection mechanism is configured to be selectively transitioned between a closed position to support parcels and an open position to allow parcels identified as unconveyable to pass through the trapdoor rejection mechanism. Each trapdoor rejection mechanism includes a first door, a second door, and one or more actuators which can be selectively actuated to rotate the first door and the second door and transition the trapdoor rejection mechanism between the closed position and the open position. The trapdoor rejection subsystem can be utilized in a conveyor system in combination with one or more robot singulators, an upstream conveyor, a place conveyor, and a vision and control subsystem. Detection of unconveyable parcels and the transition of each trapdoor rejection mechanism of the trapdoor rejection subsystem is controlled by the vision and control subsystem.

Abstract: A method and system for communicating with IoT devices to gather information related to device failure or error(s) is disclosed. The system makes a copy of at least a portion of the device's non-volatile memory and/or receives IoT device data (e.g., sensor data and/or log files etc.) from an IoT device that recently failed. The system determines which log files and/or sensor data, for example, the IoT device created before and/or after a failure. After gathering this information, the system stores the information in a database, sends it to the IoT device manufacturer, for further analysis and diagnostics to troubleshoot the failure and send a fix or software update to the IoT device.

Abstract: Techniques in advanced deep learning provide improvements in one or more of accuracy, performance, and energy efficiency. An array of processing elements performs flow-based computations on wavelets of data. Each processing element has a compute element and a routing element. Each router enables communication via wavelets with at least nearest neighbors in a 2D mesh. Routing is controlled by virtual channel specifiers in each wavelet and routing configuration information in each router. Execution of an activate instruction or completion of a fabric vector operation activates one of the virtual channels. A virtual channel is selected from a pool comprising previously activated virtual channels and virtual channels associated with previously received wavelets. A task corresponding to the selected virtual channel is activated by executing instructions corresponding to the selected virtual channel.

Abstract: One-dimensional data obtained by performing a Fourier transform on a digitally converted frequency modulated continuous wave (FMCW) radar signal at every pulse repetition interval is input to a recurrent neural network (RNN) to find the probability of the existence of a target in each range index. The range indices, i.e., bit frequencies are selected based on the probability. In order to reduce the size of the RNN, windowing may be applied. In addition, a speed-index-specific coefficient value may be calculated by accumulating and performing a Fourier transform on the selected bit frequencies in which the target exists over a plurality of pulse repetition intervals. Thus, it is possible to calculate the speed of the target.

Abstract: A microprocessor for mitigating side channel attacks includes a memory subsystem that receives a load operation that specifies a load address. The memory subsystem includes a virtually-indexed, virtually-tagged data cache memory (VIVTDCM) comprising entries that hold translation information. The memory subsystem also includes a data translation lookaside buffer (DTLB) comprising entries that hold physical address translations and translation information. The processor performs speculative execution of instructions and executes instructions out of program order. The memory system allows non-inclusion with respect to translation information between the VIVTDCM and the DTLB such that, for instances in time, translation information associated with the load address is present in the VIVTDCM and absent in the DTLB.
