The controller is configured to receive data from the sensor of the drone, determine the status of refuse within the scan area based on the data from the sensor of the drone, and at least one of generate a route for the refuse vehicle based on the status of refuse within the scan area, modify a route for the refuse vehicle based on the status of refuse within the scan area, and provide a signal to the refuse vehicle regarding the status of refuse within the scan area.

Abstract: A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.

Abstract: A flame arrestor system includes a heat exchanger through which a cooling gas flow stream is directed. A zone adjacent the heat exchanger is susceptible to possible flame and through which the cooling gas flow stream is directed. A flame arrestor containing a passage-structure matrix is disposed between the zone and the heat exchanger to quench flame from entering the heat exchanger.

Abstract: A holographic sound field device. The device includes a frame, one or more transducers configured to produce a holographic sound field, a controller configured to generate and transmit vibration signals to the one or more transducers. The device can be used to transmit vibrations and/or sound into a person's body to promote healing, relaxation, regeneration, and/or meditation.

Abstract: A compressor system is provided with an impeller disposed to rotate in a compressor chamber. A diffuser extends around the impeller to collect fluid leaving the impeller. Main flow is discharged from the diffuser through an exit providing an opening that extends circumferentially around the compressor. A bleed annulus extends around the compressor and has a consistent cross-sectional area. A bleed port that opens the diffuser to the bleed annulus and that is configured to divert a bleed flow of the fluid from the main flow before discharge through the exit. The bleed port has a circumference around the compressor and a flow size that varies around the circumference. Variation in the flow size of the bleed port maintains a uniform flow distribution around the exit.

Abstract: A computer-based method includes classifying motion in a video file using a classifier to produce a confidence score for the video file that indicates how confident the classifier is that motion in the video file is a particular type of motion (e.g., motion by a living being). The method further includes enabling a first human user to specify (e.g., with a slider-style graphical control element), from a first user computing device, a first threshold confidence score for receiving notifications about videos. The method further includes sending a first notification of the uploaded video file if the confidence score for the video file meets or exceeds the user-specified first threshold confidence score for receiving notifications about videos. The first notification, if sent, is accessible at least from the first user computing device.

Abstract: A precooler system having a symmetrical precooler core that is optimized to be integrally mounted to the turbofan engine, regardless of the turbofan engine size, is provided. The provided precooler system optimizes available space between a turbofan engine and the nacelle, and does not substantially increase weight and cost. The provided precooler system may be flexibly implemented as either a right handed precooler system or a left handed precooler system.

Abstract: A method includes receiving an indication that an event has occurred in a physical space being monitored by a monitoring device that includes a plurality of sensors. In response to the indication, the method includes sending one or more primary notifications of the event over a computer-based network to each of one or more persons primarily associated with the physical space being monitored. If, after a designated amount of time, none of the primary notifications have been viewed by any of the persons primarily associated with the physical space being monitored, the method includes sending a backup notification of the event over the computer-based network to one or more persons designated as backup contacts. The backup notification is logically associated with information that the one or more backup contacts can access about the event. The logical association can be embodied by a link (e.g., a hyperlink) in the backup notification.

Abstract: An apparatus includes: a video camera configured to acquire a video of a monitored physical space, a computer-based memory buffer configured to store temporarily a portion of the video acquired by the video camera as it is acquired, and an actuator configured such that operation of the actuator causes, for a period of time, any video subsequently acquired by the video camera to be saved to a computer-based memory device other than the computer-based memory buffer.

Abstract: A method includes: collecting data about a first event at a first physical space using a first electronic monitoring device that is physically located at the first physical space, enabling the collected data to be displayed at a computer-based user interface device (e.g., at a user's a smartphone that may be remotely located relative to the first electronic monitoring device), enabling the user to describe, using the computer-based user interface device, the first event represented by the collected data, and storing, in a computer-based memory, a logical association between the user's description of the first event and one or more characteristics of the collected data.

Abstract: A bleed air duct that preferably includes an inlet section configured to include a flush scoop and a louver. The louver is located and configured such that in the desired operating flow range of the duct, the fluid entering the flush scoop is disturbed and as a result creates a low pressure region downstream of the louver. The low pressure region substantially eliminates the generation of any pressure pulses and acoustic resonance also known as Helmholtz resonance.
