Abstract: A method for a municipality to control, track, and monitor waste or refuse receptacles requires a permit for use of a waste receptacle. An issuing organization issues a permit associated with a discreet receptacle identifier. An RFID tag is provided with the permit and attached to a discreet receptacle. The RFID tag transmits a signal carrying data associated with the discreet receptacle identifier. The signal may be read by a portable reader carried by municipal personnel to record violations of municipal code associated with the use of the discreet receptacle.

Abstract: A method can include establishing, by a computing system, a secure electronic network connection to an electronic agent running configured to access the dataset to dynamically generate the metadata related to the dataset on a client computing system. A method can include receiving, by the computing system, from the electronic agent via the secure electronic network connection, metadata related to a dataset, the metadata comprising a plurality of attributes of the dataset and a summary of the dataset. A method can include applying a valuation model to the metadata to determine an estimated value of the dataset, the valuation model comprising a machine learning model trained using marketplace data comprising sales prices and attributes of one or more datasets, wherein the model is trained to output the sales prices of the one or more datasets. A method can include determining, an estimated value of the dataset.

Abstract: An impeller assembly for a snowthrower includes a driven shaft configured to rotate about an axis, a flexible impeller configured to rotate about the axis and extending horizontally across substantially a complete width of the impeller assembly parallel to the axis, and a rigid cutting implement. The flexible impeller extends radially from the driven shaft to an impeller radial distance. The rigid cutting implement extends radially from the driven shaft to a cutting implement radial distance less than the impeller radial distance, wherein the rigid cutting implement is spaced apart from and does not contact the flexible impeller.

Abstract: An impeller assembly for a snowthrower includes a driven shaft configured to rotate about an axis, a flexible impeller paddle coupled to the driven shaft for rotation about the axis, and a rigid cutting implement coupled to the driven shaft for rotation about the axis. The flexible impeller paddle is configured to clear snow from a surface to be cleared. The flexible impeller paddle extends radially from the axis to a paddle radial distance. The rigid cutting implement is configured to break up snow or ice on the surface to be cleared. The rigid cutting implement extends radially from the axis to a cutting implement radial distance less than the paddle radial distance.

Abstract: A microporous marking structure, a hand stamp and methods of manufacturing a hand stamp is disclosed. The microporous marking structure includes a noncontinuous pattern of sealed portions on the rear surface thereof. The microporous marking structure may be mounted for use in a pre-inked hand stamp which can be used to create numerous impressions without reinking.

Abstract: A permanent closure for fuel tanks mounted to an access door (28) with a hinge (30) connected to a vehicle, having an extended housing (22) which contains a rubber gasket (14) on the interior base, a spring (16) and a slideable internal fuel cap (24) Which meets EPA specifications. When the hinged access door (28) is in a closed position, a filler tube (20) on the vehicle enters a hole (10) in the extended housing (22) which meets the internal fuel cap (24) and an o-ring (12). A seal is obtained by closing the hinged access door (28) which presses the internal fuel cap (24) and the o-ring (12) against the filler tube (20), and into the rubber gasket (14) at the interior base of the extended housing (22). A locking pin (26), contacting a notch in the extended housing (22), insures the access door (28) remains closed, thus providing a continuous seal, and when released by a latch in the passenger compartment, maintains a seal, yet the spring partially urges the hinged access door (28) open.
