摘要:
A circuit breaker is disclosed which has first and second electrodes that can be contacted to complete a circuit or withdrawn from each other by some suitable mechanism to break the circuit. During breaking of the circuit, an electric arc is created. The circuit breaker includes means for providing gas pressure below atmosphere around the electrodes, at least at the time the arc is struck. The circuit breaker also includes a shield arranged in proximity to the electrodes which is ablated by the action of the arc. The shield's arrangement and material are chosen such that, when ablated, the shield releases gas to assist in extinguishing the arc.

A print engine is disclosed. The print engine includes a transfer medium to apply print content to a print medium, a preheat platen to heat the print medium prior to applying the print content and a substrate formed to cover the preheat platen.

A blade assembly suited for both blending and food processing in small throat blender jars is provided. The blade assembly comprises a plurality of blade forms each designed to perform a specific blending or processing task while simultaneously working together and with the geometric restrictions of the jar to optimize the assembly's capability to crush ice, blend or mix liquids and/or semi-solid materials, and to chop, cut, or slice solid food items without the need for user interaction to clear compacted items from the blades and/or the walls or bottom of the jar during its operation. The improved performance also serves the beneficial side effect of improved bearing and motor life in the blender/food processor.

An electrical energy source, particularly suitable for portable emergency equipment such as cardiac defibrillators, uses a small explosive charge of which the energy is converted into a short intense electrical pulse by an electromechanical convertor for example a piezoelectric transducer.
摘要:
A method for monitoring the mass of an object (10) is provided, the method comprising the steps of: (i) applying a vibratory force to the object (10) so that the object vibrates in whole or in part, (ii) providing a sensor or sensors (14) configured to measure vibrations of the object in response to the force, (iii) measuring vibration data from the sensor(s) (14), and (iv) comparing the vibration data or a parameter derived therefrom to reference data or one or more reference parameters, so as to determine the mass of the object or an indication that the mass of the object (10) differs from that indicated by the reference data or one or more reference parameters. Preferably, the object (10) is a vehicle. The vibratory force may be provided by an integral vehicle component, for example a vehicle engine (12).

摘要:
An assembly is provided for fixing the position of an adjustable component (22) of a vehicle, comprising in combination a fixed reference frame (20) within the vehicle such as a dash or a firewall, an adjustable component (22) also disposed in the vehicle such as an adjustable steering column (10), pedals, or a seat. Interconnecting the fixed reference frame (20) and the adjustable component (22) is a fluid locking mechanism (50) which permits selective positioning of the adjustable component relative to the fixed reference frame (20) and holds the adjustable component (22) in position. The fluid locking mechanism (50) is preferably a non-Newtonian flow fluid locking mechanism which uses a magneto-rheological fluid (97) to fix the position of the adjustable component (22) in place once the desired position is selected. To provide additional safety for the vehicle occupants, the fluid locking mechanism may be controlled by an electrical microprocessor (556) or circuit which adjusts the locking strength of the fluid locking mechanism (50) based upon user inputs and dynamic events.
摘要:
A trellis is disclosed. The trellis has a base, spaced flexible arms rising generally vertically upwardly and outwardly from the base to free ends, and two spacers. There are openings in each of the spacers in which the arms of the trellis are slidable. The walls of the openings in the spacers engage the flexible arms frictionally, exerting a force which opposes sliding movement of the spacers relative to the flexible arms.
