This invention relates generally to electronics, mechanics, and software, and more specifically, to systems and methods for wirelessly monitoring a brochure box. In one embodiment, the invention includes an apparatus that provides for remote content monitoring, the apparatus including a receptacle, the receptacle configurable to storing content; and a sensor node, the sensor node disposed proximate to the receptacle, the sensor node associated with a unique identifier, the sensor node configurable to monitor the existence of any stored content, the sensor node configurable to transmit a signal containing the unique identifier to a remote device, the signal being any of a cellular, satellite, and wireless network signal.

Novel tools and techniques are provided for implementing item or luggage loss prevention, which, in some cases, is based on weight measurement. In some embodiments, a device with a processor can be placed under a bag's handle, within an interior compartment of the bag, below or in the feet or wheels of the bag, and/or the like. The device can allow a user to lock in a weight of the bag. If any item is subsequently removed from (and not returned to) the bag, the device will notify the user, using one or more of audio notification, visual notification, and/or mobile device notification (e.g., via e-mail, text message, SMS, MMS, chat message, and/or the like) that the weight of the bag has changed. In some cases, location detection devices may be implemented to allow the user to backtrack where the missing item might have been left behind.

A computer-implemented method and system for estimating fluid loss. A graphical representation of a container is displayed. User inputs to display elements may include incrementing or decrementing sliding markers to desired set positions. A first user input may indicate a volume of a second fluid, and a second user input may indicate a total volume of fluid. A first volume of a first fluid may be estimated based on the first and second user inputs. A graphical representation of the first volume of the first fluid may be displayed as a fluid level within the graphical representation of the container. A second volume of the first fluid contained in an absorbent article may be estimated based on a difference between a dry weight and a wet weight measured on a scale. A quantity of the first fluid may be estimated based on the first and second volumes.

An agricultural system includes: one or more weight sensors that detect a weight of material in a first material receptacle and generate sensor data indicative thereof; one or more processors; memory; and computer executable instructions, stored in the memory, that, when executed by the one or more processors, configure the one or more processors to: determine a change in weight of material in the first material receptacle based on first sensor data indicative of a weight of material in the first material receptacle at a first time and second sensor data indicative of a weight of material in the first material receptacle at a second time; determine a material transfer rate indicative of a rate at which a material transfer subsystem transfers material based on the determined change in weight; and determine a fill level of material in a second material receptacle based on the determined material transfer rate.

A computer-implemented method for quantifying blood on one or more absorbent items is provided. The method includes receiving data indicative of a quantity of each type of the absorbent items to be used in a medical procedure, accessing a dry weight for each type of the absorbent items, and determining a total dry weight based on the dry weight for each type of the absorbent items. Measurement signals are received from a scale measuring the absorbent items containing blood. An occurrence of a weighing event may be determined using a machine learning algorithm trained on a training data set of scale signal patterns. A wet weight of the absorbent items associated with the weighing event is received. A volume of blood contained in the absorbent items is determined based on the wet weight and the total dry weight. The volume of blood is displayed on a display.

A ship weighing system and a weighing method thereof include a collection module, a computing server, a wireless router, a display control terminal, and a network switch, which are installed in the ship. The collection module synchronously collects water level data of a stern and trim angle data of a front portion, a middle portion, and a rear portion of the ship. The computing server respectively calculates, based on the water level data collected by the collection module, an accumulated volume of the ship below a slice section parallel to a bottom plane of the ship corresponding to the water level data and a volume of a trim wedge formed by the slice section and an actual horizontal plane. The computing server combines results and corrects a volume of a vertical arch wedge in the middle portion of the ship to obtain a displacement volume of the ship.
