Abstract: A method of making and a computer readable media having data readable by a fish finder are provided. The data includes a topographical fishing map usable by the fish finder to display bathymetric information regarding a body of water, and a number of water current flow simulations. Any of the number of simulations is selectable via the user input and usable by the fish finder to display water current flow as a layer on the bathymetric information regarding a body of water. Freshwater currents or saltwater tides may be provided in certain embodiments. The method includes inputting the bathymetric information from the topographical fishing map and current flow conditions to the processor, processing a hydrodynamic or tidal modeling program and storing the water current flow simulation as a user selectable layer on the media on which the topographical fishing map is stored.

The virtual environment may be updated to display virtual features associated with the communication session.

Abstract: The present invention relates to welding sleeve preferably comprised of a fabric, leather, or leather-like synthetic material. There is an adjustable, secure means for attaching the welding sleeve to the lower arm of a user or to the upper arm of the user depending upon the relative position of the user compared to that of the materials to be welded. In certain preferred embodiments of the present invention, the fabric may be impregnated with or made from a flame retardant material. Multiple welding sleeves may also be used to protect the upper and lower arms of a user.

Abstract: A system for detecting an occupant in a vehicle seat that includes a sensing electrode located in a seat bottom of a vehicle seat. The system also includes a shield electrode located in the vehicle seat below the sensing electrode. A sensing circuit is operatively coupled to the sensing electrode and the shield electrode. A controller is operatively coupled to the sensing circuit, wherein the controller operates to configure the sensing circuit to apply current to the shield and sensing electrodes. The controller is configured to detect the presence of an object in the seat by comparing a measure of the quadrature component of the sensing current to a threshold wherein the measure is adjusted by an offset value that varies based on a value of a non-volatile counter.

Abstract: A multiple-stage amplifier includes a driver stage die and a final stage die. The final stage die includes a III-V semiconductor substrate (e.g., a GaN substrate) and a first transistor. The driver stage die includes another type of semiconductor substrate (e.g., a silicon substrate), a second transistor, and one or more secondary circuits that are electrically coupled to a control terminal of the first transistor. A connection (e.g., a wirebond array or other DC-coupled connection) is electrically coupled between an RF signal output terminal of the driver stage die and an RF signal input terminal of the final stage die. The secondary circuit(s) of the driver stage die include a final stage bias circuit and/or a final stage harmonic control circuit, which are electrically connected to the final stage die through various connections.

Abstract: Provided herein is a device (and associated method of using the device) to aid and educate a child in blowing their nose. The device comprises a pinwheel assembly, which is positioned under the child's nostrils such that air expelled from the nostrils will turn the blades of the pinwheel. The device optionally comprises a pacifier, which is configured such that when the nipple of the pacifier is in the child's mouth, the pinwheel assembly is positioned such that air expelled from the child's nostrils will turn the blades of the pinwheel assembly. Other configurations include cups, which encircle the child's mouth, and handles which aid in the proper positioning of the device.

Abstract: An air compressor assembly is disclosed. The air compressor assembly includes a substantially curved frame including a lower frame portion and an upper frame portion, a fluid tank carried by the lower frame portion, a compressor mechanism carried by the lower frame portion, and a storage bin including an engagement mechanism releasably coupled to the upper frame portion.

Abstract: An air compressor includes a housing assembly and a compressor system positioned substantially within the housing assembly. The compressor system is operable to compress ambient air. The air compressor also includes a tank positioned substantially within the housing assembly in communication with the compressor system to receive pressurized air from the compressor system. The tank has a generally flattened spherical shape with a diameter and a width that is less than the diameter. The tank is oriented generally vertically within the housing assembly such that the diameter represents a height of the tank.
