Abstract: Embodiments are disclosed for crash detection on one or more mobile devices (e.g., smartwatch and/or smartphone). In some embodiments, a method comprises: detecting, with at least one processor, a crash event on a crash device; extracting, with the at least one processor, multimodal features from sensor data generated by multiple sensing modalities of the crash device; computing, with the at least one processor, a plurality of crash decisions based on a plurality of machine learning models applied to the multimodal features; and determining, with the at least one processor, that a severe vehicle crash has occurred involving the crash device based on the plurality of crash decisions and a severity model.

Abstract: A chemical pre-concentrator includes a conduit defining a flow path between two ends and having a heating element disposed within the conduit, such that the heating element has at least one sorbent material deposited directly on at least a portion of a conductive surface of the heating element. Some such heating elements are in the form of electrically conductive strips defining both a plurality of apertures through the strip and a series of undulations spaced along the flow path.

Abstract: A chemical analysis system is disclosed wherein, in evacuating a preconcentrator housing (2) prior to desorption, a pump system (13) reduces an internal pressure of the preconcentrator housing to a level substantially equal to an internal pressure of a chemical analyzer such that flow restrictors and/or membranes (15) between the chemical analyzer (7) and the preconcentrator housing (2) may be omitted. The chemical analysis system includes a chemical analyzer (7), a preconcentrator housing (2) coupled to the chemical analyzer, the preconcentrator housing enclosing a temperature control element (5, 18) and a sorbent material (1), the temperature control element configured to heat the sorbent material to adsorb or desorb a chemical of interest; and a pump system (13) coupled to the preconcentrator housing and the chemical analyzer, the pump system configured to evacuate the preconcentrator housing prior to desorption of the chemical of interest.

Abstract: In one general aspect, a sample is transferred into a mass spectrometer by capturing a sample on a collector, inserting the collector into a sample chamber coupled to the mass spectrometer and a vacuum pump, evacuating the sample chamber using the vacuum pump to reduce an internal pressure of the sample chamber to a level less than atmospheric pressure, heating the collector to release the sample from the collector, and introducing the sample into the mass spectrometer from the evacuated sample chamber.

Abstract: A foodstuff container to be held in a cup receptacle of the armrest of a theater seat. The container has a large generally cylindrical popcorn-holding portion affixed to a base which is shaped on the outside the same as a conventional beverage cup.

Abstract: An improved foodstuffs container configured to be readily received with a cup holder having a relatively standard size recess such as that commonly provided in armrests of many theater chairs so as to hold the container while the patron is not eating or optionally, drinking from the cup is disclosed. The container includes a walled tray structure supported by a contiguous container base sized and shaped to be supported within the standard cup holder. The walled tray structure may be configured with a planar or other shaped bottom, with or without partitions to received the desired foodstuffs either in volume or in discretely separated portions. The container base has an interior recess contiguous with the volume of the walled tray structure to receive and support additional foodstuffs readily accessed from above.

Abstract: A device is disclosed for warming tortillas and other foods. The device operates with a standard electric alternating current ranging from 110 to 120 volts in the US and 220v -240v in other countries. This appliance is to be used in homes or in businesses for the purpose of warming either corn or flour tortillas in quantities ranging from one up to six at a time. The electric current provides energy to heater elements located within the unit and thus provide the heat necessary to warm the tortillas placed on a plurality of circular loading trays. The loading trays are specially designed to lock-in-place in the open and closed positions and are designed to work with a vertical pivot tube which allows the loading trays a pivot-swivel action for efficiency in the loading and unloading of tortillas.
