    摘要： Techniques are disclosed for detecting human presence and tracking motion within a given area using light reflections. Activity is detected by receiving light encoded with source-identifying data reflected from the area and sensing changes, caused by human presence in the area, from a previously established baseline in the light reflection profile for the area. The baseline is updated over time based on human movement and/or as the area changes. Location-indicative changes in the current baseline that are greater than a certain threshold indicate a change in occupancy state of that location. In some embodiments, lightguides are used to define a specific field-of-view for the sensors. The combination of a known field-of-view and a known source of reflected light allows location of each occupant's activity to be tracked within the area. Occupancy can be detected or inferred based on activity tracked entering the area followed by lack of an exit event.

    摘要： A novel chewing gum box includes a gum storage chamber, a storage chamber cover, a funnel apparatus, a gum introducing plate, a gum carrying groove, a carrying groove baffle, a push handle, a spring baffle, guide rails, guide rail grooves, a spring groove, and a spring. The gum storage chamber is communicated with the gum carrying groove through the funnel apparatus. The gum carrying groove is connected to the push handle and is capable of reciprocating along the guide rails and the guide rail groove. When retrieving gum, the box body is tilted and shaken first to allow gum in the storage chamber to slide along the gum introducing plate into the gum carrying groove via the funnel apparatus. The push handle then is actuated to have the gum pushed out along the guide rail and the guide rail groove, so that the gum is available for retrieval.

    摘要： Systems, methods, and software for determining whether or not a monitored space is occupied by one or more humans and/or animals. In some embodiments, one or more radio-frequency (RF) receivers monitor(s) one or more RF frequencies for changes in received signal strength that may be due to changes in occupancy of the space being monitored. The received signal strength is analyzed using nonparametric online change-point detection analysis to determine change-points in the received signal(s). One or more statistical measures of the received signal(s), such as mean and variance, are used in conjunction with the change-point detection to determine a probability that the occupancy of the monitored space has changed. In some embodiments, additional sensors and/or machine learning can be used to enhance the performance of the disclosed occupancy-detection methodologies.

    摘要： The present invention relates to a technical field of a tool glove combining with various tools, more particularly to a tool glove applied for construction, civil engineering, outdoor sport, agriculture, forestry, butchery, catering, fishery, husbandry or horticulture. In addition, the tool glove of the present invention can combine with various replaceable toolheads upon working demand, such as building repair, high scaffold assembly/disassembly, hitting work, mountain climbing sport, tree climbing for picking fruit, meat cutting in butchery, peeling and vegetable-fruit cutting in catering, scales removing and fish-shrimp cutting in fishery or husbandry, boring for growing flower in horticulture, earthmoving, painting by using brush or roller in painting works, so that it is not necessary for a user to carry multiple dedicated tools to complete various works.
