Abstract: A method and an apparatus for automatically detecting the intactness of ground electrodes in the bath of an induction furnace are described. According to the method a low DC or AC current is applied to an additional insulated electrode extending through the furnace bottom and being in connection with the melt. After melting of the charge this current is measured and compared with a reference value. If the magnitude of the current drops below the reference value an alarm signal is generated. Furthermore, methods and devices for localizing a ground fault are described. By this, the security of the operation of an induction furnace is improved.

Abstract: A method and an apparatus for detecting a ground fault in an induction furnace as well as an induction furnace are described. When a ground fault is detected by means of the ground-fault detector the ground fault is localized. By doing this it is determined if the ground fault is caused by a failure of the refractory lining or by other reasons. If the ground fault is caused by other reasons it is ascertained if it is caused by a defective magnetic yoke insulation. Furthermore, it can be ascertained which magnetic yoke of the induction furnace causes a ground fault. In this manner the induction furnace can be operated with improved security and smaller expense.

Abstract: Functional encryption (FE) ciphertext is transformed into partially-decrypted (PD) ciphertext. The PD ciphertext has a shorter bit length than the FE ciphertext, or the decryption time of the PD ciphertext is less than the decryption time of the FE ciphertext. The FE ciphertext can be an attribute-based encryption ciphertext. The transformation can be performed with a transformation key generated by an authority with a master key or by a user with a decryption key. The transformation can also be performed, without a transformation key, based on unencrypted components of the FE ciphertext and on auxiliary information associated with the unencrypted components of the FE ciphertext. The PD ciphertext can require less transmission time across a network than the FE ciphertext. The PD ciphertext can require less time to decrypt than the FE ciphertext, particularly when the computational resources performing the decryption are limited.

Abstract: Methods and structures for manufacturing and assembling matching parts in a manufacturing line are described. In some embodiments, the parts are portions of a consumer product, such as an electronic device. The matching parts are manufactured and assembled in a way such that the interface between the matching parts is substantially seamless. In some embodiments, the interface has a feature with curved portions. Methods involve measuring the dimensions of a primary part and custom machining a secondary part to seamlessly fit with the primary part. In this way, the secondary part is made to uniquely fit the primary part. The primary and secondary parts can be marked to identify them as matching parts in a manufacturing environment where numerous pairs of parts are made.

Abstract: A cooking appliance includes a cooktop and a grate. The cooktop includes a bottom surface on which at least one gas burner is mounted. The cooktop further includes a periphery and an inner recessed area. The inner recessed area is recessed relative to the periphery. The inner recessed area is substantially defined by the bottom surface. The cooktop further includes a transition extending between the periphery and the inner recessed area and a sweep section extending between the periphery and the inner recessed area. The inner recessed area is surrounded substantially by the transition except at the sweep section. The grate is configured to be placed on the cooktop. Each of the sweep section and the transition extends between the bottom surface and a predetermined elevation above the bottom surface. The sweep section reaches the predetermined elevation in a more gradual manner than the transition reaches the predetermined elevation.

Abstract: Various techniques for detachably connecting a commercially-available convention picture frame to an electronic display panel, such as one used in a digital picture frame. The electronic display panel includes a display and a bordering housing surrounding the display and having an opening, that in combination with the opening in the conventional picture frame, allow the display to be visible through the openings. The height, width, and thickness of the bordering housing are configured to allow the electronic display panel to be engaged with multiple commercially-available conventional picture frames.

Abstract: A golf green reading device has a lens with a reference line that is illuminated when the reference line is in a horizontal or vertical orientation. The reference line is illuminated by an electrical circuit secured within a housing having a power source, a light source, and a level switch. The user holds the device in a horizontal or vertical orientation to read the slope of a golf green relative to the reference line and determine the correct line to putt the golf ball.
