Abstract: Described herein are methods of recycling polypropylene based personal protective equipment. The method may comprise the steps of: (a) conveying a feed of personal protective equipment; (b) cleaning at least a portion of the feed of personal protective equipment; (c) fragmenting the personal protective equipment into a plurality of fragments, the plurality of fragments comprising non-polypropylene fragments and polypropylene fragments; (d) separating at least a portion of the non-polypropylene fragments from the polypropylene fragments to produce a batch of polypropylene fragments; and (e) pelletizing the batch of polypropylene fragments to produce polypropylene pellets.

Abstract: A device for analyzing gas emitted from skin includes: an enclosure for collecting the gas emitted from skin, the enclosure having: an inlet through which a carrier gas is flown; and an outlet through which the carrier gas and the gas emitted from skin is flown into a vertical gas sensor, such that the vertical gas sensor has: a substrate; a collector layer; an emitter layer positively biased relative to the collector; a metal grid with a metal layer having openings, the metal grid located in between, but not in direct contact with, the collector and emitter; and an organic semiconductor (OSC) layer located in between the collector and emitter.

Abstract: A communication device includes a transceiver and a control circuit. The control circuit determines whether to transmit a second MKPDU in advance according to a member identifier of a peer device carried by a received first MKPDU and one or more lists maintained by the communication device. When the member identifier of the peer device is not recorded in the one or more lists, the control circuit determines to transmit the second MKPDU in advance. When the control circuit determines to transmit the second MKPDU in advance, the control circuit generates the second MKPDU, encodes the second MKPDU to generate a frame, and transmits a signal carrying the frame through the transceiver, wherein a time interval between the transmission of the signal and a previous transmission performed by the transceiver is less than a predetermined transmission period.

Abstract: A portable power station (PPS) unit includes a controller that receives AC current information of AC input current at an AC input port and produces a control signal that is used to control the PPS unit to operate as a voltage source or a current source, and to control an AC output current at substantially the same magnitude, frequency, and phase as the AC input current. A PPS apparatus includes two or more PPS units connected together such that the AC output power of one PPS unit is connected to the AC input port of a next PPS unit; wherein a first PPS unit is a voltage source and each of the second or more PPS units is a current source, and a total AC output power of the PPS apparatus is substantially a sum of the AC output power produced by the two or more PPS units.

Abstract: An ocular device is disclosed along with methods for the employment thereof. In one aspect, a device for placement into a lacrimal punctum or conjunctival sac of a person includes one or more sensor materials responsive to one or more components of the chemical composition of the person's tears.

Abstract: An information processing apparatus used for an additive manufacturing system includes a circuitry configured to calculate a contact area of a contact face of a three dimensional (3D) model that contacts a base member of an additive manufacturing apparatus, calculate an adhesive force that is to occur to the contact face of the 3D model and the base member, rotate the 3D model by changing an angle of the 3D model with respect to a 3D modeling area, calculate a warping force that is to occur to the 3D model when the 3D model is to be formed into a 3D object under each orientation set for the 3D model by rotating the 3D model by changing the angle of the 3D model with respect to the 3D modeling area, and search for a target orientation of the 3D model where the warping force becomes smaller than the adhesive force.

Abstract: A modeling processing system is provided. The modeling processing system includes an acquisition unit, a memory, and a searching unit. The acquisition unit acquires information on a surface profile of a target three-dimensional object from a reading unit. The target three-dimensional object is a target for a modeling processing. The memory stores, for a plurality of modeled objects, a plurality of modeled object information, and each modeled object information includes surface profile information and internal structure information of the modeled object. The searching unit specifies, from among the plurality of modeled object information stored in the memory, at least one of the plurality of modeled object information based on the information on the surface profile of the target three-dimensional object acquired by the acquisition unit, as a candidate modeled object information for the modeling processing.

Abstract: A storage device is capable of switching its wireless sharing mode while sensing occurrence of a flip-over on itself. With the aid of the storage device, a user may easily and intuitively activate an operation of sharing information with other external storage devices or determine a degree of sharing the information.
