Microwave heating apparatus
The present invention includes a directional coupler that detects at least part of a reflected wave inside a waveguide. When an object to be heated is absent, a reflected wave is strong, because there is nothing to absorb a microwave.

Handling deletes with distributed erasure coding
Inter-zone network traffic generated during deletion of a data chunk that has been replicated by employing geographically distributed (GEO) erasure coding is reduced. In one aspect, if a data chunk is to be deleted, partial coding chunks are generated by a source zone and provided to destination zones that store complete coding chunks for updating the complete coding chunks based on combining them with the received partial coding chunks. In another aspect, if a first data chunk is to be deleted and a second data chunk is to be replicated, partial coding chunks are generated by the source zone for each data chunk.

Method and apparatus for mechanical energy harvesting using variable inductance magnetic flux switch
A method of mechanical-to-electrical energy conversion utilizes a mechanical spring in combination with a rapid-action variable inductance magnetic flux switch to convert a spring-loaded mechanical energy into a change in magnetic flux captured by an electrical coil element within the magnetic flux switch. The change in coil inductance and magnetic flux induces a current to flow through the electrical coil in the form of a a pulse of electrical energy that may be stored. The electrical coil is coupled to the mechanical spring so that each time the spring is released, the coil moves with respect to a magnetic core and a change in flux is created. The application of an external mechanical force (such as human locomotion) functions to compress and subsequently “unlock” the mechanical switch, allowing for the electrical energy associated with the application of aperiodic forces to be harvested. |

Arrangement for battery pack protection during fluid ingress
An arrangement for battery pack protection during fluid ingress. The battery pack may include a housing, a terminal block, and a core battery assembly supported in the housing, the assembly including a core housing, a plurality of battery cells supported in the core housing, a first weld strap connecting the battery cells to a positive power terminal, a second weld strap connecting the battery cells to a negative power terminal, a first sacrificial electrode connected to the first weld strap, and a second sacrificial electrode connected to the second weld strap. A spacing between the first sacrificial electrode and the second sacrificial electrode may be selected such that an ingress fluid entering the battery pack electrically shorts the first sacrificial electrode and the second sacrificial electrode to drop a voltage of the cell battery assembly and discharge battery energy before damaging the battery cells. |
