Abstract: A headphone ear pad system may generate a custom ear pad from a three-dimensional data set of a user. The custom ear pad is attach to a headphone housing and is subsequently used to form an acoustic coupling with an ear of the user and an acoustic driver of the headphone housing. The custom ear pad can have a customized cross-sectional shape and sealing surface to create an optimized acoustic profile for the user.

Abstract: The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit is an array of lancets set in wells in a rigid base. Each lancet well is covered by a protective cover which when deformed permits the lancet to puncture a user or other patient. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.

Abstract: A packaging arrangement for a wearable ornament, such as a pin-backed figurine that is supplied with a loop backer enabling the figurine to be coupled with a rope or chain, includes a post for display of the figurine using with the loop backer when not being worn. The figurine on the post may be snapped into a base, the base having a base top and base bottom that are separable from one another. A transparent cover encloses the figurine on the post atop the base, with a backing held in place behind the figurine in the packaging by retention tabs proximate to top corners of the transparent cover, by alignment ridges of the base top and by support posts inside the base bottom. The figurine may therefore be worn either through being pinned or on a rope or chain, or may be displayed either on just the post or on the post atop the base.

Abstract: A parallel processing system includes at least three processors operating in parallel, state monitoring circuitry, and state reload circuitry. The state monitoring circuitry couples to the at least three parallel processors and is configured to monitor runtime states of the at least three parallel processors and identify a first processor of the at least three parallel processors having at least one runtime state error. The state reload circuitry couples to the at least three parallel processors and is configured to select a second processor of the at least three parallel processors for state reload, access a runtime state of the second processor, and load the runtime state of the second processor into the first processor. Monitoring and reload may be performed only on sub-systems of the at least three parallel processors. During reload, clocks and supply voltages of the processors may be altered. The state reload may relate to sub-systems.

Abstract: One embodiment provides a system and method for predicting network power usage associated with workloads.

Abstract: Electric multiple stage variable forced air induction systems are disclosed herein. A housing defines a conduit therethrough with an exit (output) opening and an entry (intake) opening. The exit opening is to couple to and provide airflow to an air intake opening of a combustion engine. The entry opening is to receive air for delivery through the conduit to the exit opening. A plurality of stages generate thrust to increase airflow through the conduit and to the air intake opening of the combustion engine. Each stage can comprise a turbine housing component, a turbine rotor to rotate about an axis and generate thrust on air as it passes through the conduit in a direction parallel to the axis, and a motor coupled to and configured to turn the turbine rotor. One or more processing devices receive inputs indicating engine parameters and control the motor of each stage.

A portion of the generated electrical power is communicated to water electrolyzers which produce oxygen and hydrogen from water as gases. At least a portion of the generated hydrogen gas is transferred to a transportation ship via a hose-carrying, remotely operated (or otherwise unmanned) vehicle, and subsequently transferred to an energy-consuming module or infrastructure, where a portion of the hydrogen is consumed in order to manifest a generation of electrical energy, a mechanical motion, and/or a chemical reaction.

Abstract: A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.
