Abstract: Enclosed are embodiments for estimating gait time events and GCT using a wrist-worn device. In some embodiments, a method comprises: obtaining, with at least one processor of a wrist-worn device, sensor data indicative of acceleration and rotation rate; and predicting, with the at least one processor, at least one gait event time based on a machine learning (ML) model with the acceleration and rotation rate as input to the ML model.

Abstract: Contemplated fully automated coffee roaster have significantly reduced energy demands, use electrical heat as a heat source in a temperature-only driven program mode, and eliminate smoke and smell within the roaster. Most preferably, contemplated fully automated roasters will consume only about 10 percent of the energy as compared to known devices on a per kilogram basis of beans and require no operator experience.

Abstract: A semiconductor memory device in which a mode of a memory bank may be independently selected and a method of controlling the semiconductor memory device may be provided. The semiconductor memory device with a plurality of banks may include a plurality of bank groups that each may have at least one bank from among the plurality of banks, and a memory controller that may control a read/write operation to be performed on a bank belonging to a bank group from among the plurality of bank groups, in response to a control signal, where different modes or the same mode may be applied to the bank groups. Accordingly, different modes or the same mode may be applied to the banks so that the read/write operation may be performed on a bank having a mode that is advantageous to the type of data, thereby minimizing consumption of power and a time delay.

Abstract: The various embodiments provide an incendiary device utilizing a multiple hollow core-burner technique that facilitates producing large diameter cuts through steel targets. To facilitate this result, the various embodiments incorporate a multiple-core burning design with multiple orifices at the base for directing multiple jets of molten reaction product at the target. The various embodiments further incorporate an optional holding device as a means for locking the device onto a target. Devices in accordance with the invention having a base diameter of 2.312″ have been shown to be capable of producing an approximately 2″ diameter hole through ¼ inch thick steel plate using a 275 g thermite charge within a container three-quarters the size of a standard AN-M14 Thermite Grenade package.

Abstract: A coffee roaster and a method for roasting beans are disclosed. The coffee roaster comprises a chamber for containing beans, a temperature adjusting means for heating or cooling the beans and the chamber, a temperature measuring means located within the chamber for measuring a beans' temperature and a chamber's temperature, and a controller. The controller calculates a first beans' temperature and a first maintain time based on the weight and a type of raw beans. The controller also controls the temperature adjusting means in order to maintain the chamber temperature as a first chamber temperature during a first maintain time when the beans' temperature reaches the first beans' temperature, and in order to continuously heat the beans during a roasting process.

Abstract: A holding device for a pyrotechnic, incendiary device. More particularly, a holding device for a thermite or thermate based destructive device or enhanced incendiary grenade. The device assembly allows for firm attachment of pyrotechnic, incendiary devices, particularly enhanced incendiary grenades, to targets having various surface shapes and orientations, or formed of various materials. The holding device is inexpensive and easily reproducible.

Abstract: A coffee bean roaster having an annular coffee bean receptacle, an air passageway extending from a source of outside air to the annular coffee bean receptacle, and a fan positioned in the air passageway operative to draw air from the outside source through the air passageway and into the annular coffee bean receptacle. An air heater is positioned in the air passageway so as to heat air propelled through the air passageway by the fan prior to entering the annular coffee bean receptacle. A chaff receptacle is positioned adjacent the annular coffee bean receptacle so as to receive chaff from beans roasted in the annular coffee bean receptacle and an air exhaust passageway extends from the annular coffee bean receptacle to a region proximate to the chaff receiving receptacle and is operative to establish an exhaust air flow that carries the chaff to the chaff receptacle.

Abstract: A destructive device containing a thermite-type composition having a core burning configuration. The device comprises a housing having a top, a bottom, and a thermally insulated liner to maximize the thermal effectiveness of an ignition. The bottom has a circumferential skirt and defines one orifice therein for directing the expulsion of the thermite-type-composition upon ignition, the top has vents which together with the bottom orifice and skirt balance the escape of gas and prevent the device from moving during ignition.

Abstract: The present invention relates to an apparatus for roasting raw coffee beans which apparatus can instantly roast a small quantity of raw coffee beans according to personal taste and provide a unique taste and fragrance of coffee, and in particular to an apparatus suitable for home use. The apparatus has a roasting vessel for containing raw coffee beans to be roasted. A plurality of air openings are provided for creating a whirling vertical motion to a heated airstream ascending therethrough, whereby the raw beans are roasted and also caused to have their hulls separated and caused to ascend upwardly with the airstream to a hull-receiving vessel.

Abstract: A quick-cooking oven equipped with a far-infrared heating tube. Heat and far-infrared radiation are generated from ceramic heating tubes. A motor for rotating a cooling fan and the heating elements are completely shielded to prevent motor failure. The cooking space can be expanded by the use of expander rings. The fan does not get soiled, and there is no need for cleaning it, and the oven can be cleaned simply.
