摘要： A computing system can include a radio transceiver and tracking manager software for tracking the location of objects such as tools. Radio frequency identification tags are attached to the objects and can communicate with the radio transceiver. During an initial registration process, the tracking manager software sends an initial registration signal to each object so that the object can be identified in a registered objects file. In one instance, the tracking manager software subsequently sends periodic interrogation signals to the objects to confirm that the objects are within a certain proximity. In another instance, after completing a task a worker can check-in each object wherein the tracking manager software sends interrogation signals to the objects to confirm that all of the objects are accounted for.

摘要： The invention provides an optoelectronic device comprising a mixed-anion perovskite, wherein the mixed-anion perovskite comprises two or more different anions selected from halide anions and chalcogenide anions. The invention further provides a mixed-halide perovskite of the formula (I) [A][B][X]3 wherein: [A] is at least one organic cation; [B] is at least one divalent metal cation; and [X] is said two or more different halide anions. In another aspect, the invention provides the use of a mixed-anion perovskite as a sensitizer in an optoelectronic device, wherein the mixed-anion perovskite comprises two or more different anions selected from halide anions and chalcogenide anions. The invention also provides a photosensitizing material for an optoelectronic device comprising a mixed-anion perovskite wherein the mixed-anion perovskite comprises two or more different anions selected from halide anions and chalcogenide anions.

摘要： A vessel with a suspension system for a handle assembly are described. For example, an apparatus can include: a hollow vessel having a body which includes one or more walls extending upwardly from a base portion to form an opening in fluid communication with an interior space of the body; a handle assembly movably coupled to the body, the handle assembly configured to slide outwardly or inwardly with respect to the vessel; and a flexible suspension member coupled to the body and to the handle assembly, the suspension member configured to at least partially suspend a weight of the vessel. The suspension member can stretch in response to outward motion of the handle assembly with respect to the vessel and compress in response to inward motion of the handle assembly with respect to the vessel.

摘要： A lighting fixture includes a voltage source circuit and a first light module comprising a first current source circuit and a first light emitting diode (LED) light source. The lighting fixture further includes a second light module that includes a second current source circuit and a second LED light source. The voltage source circuit is configured to provide a voltage source output voltage to the first current source circuit and to the second current source circuit. The first current source circuit is configured to provide a first current to the first LED light source. The second current source circuit is configured to provide a second current to the second LED light source. A voltage level of the voltage source output voltage depends on a waveform of a line dimmer output voltage that is provided to the voltage source circuit.
