Abstract: A method of protecting a superconducting magnet from quenches, the superconducting magnet having at least one primary coil comprising high temperature superconductor, HTS, material. A secondary HTS tape is provided, the secondary HTS tape being in proximity to and electrically insulated from the primary coil, and being configured to cease superconducting at a lower temperature than the primary coil during operation of the magnet. A loss of superconductivity in the secondary HTS tape is detected. In response to said detection, energy is dumped from the primary coil into an external resistive load.

Abstract: A restaurant and public eating area high chair is a high chair intended for use by infants and small children in restaurants and public eating areas. A restaurant and public eating area high chair consists of two front legs, two back legs, a seat, a backrest, a front bar, and side rails that are high enough to keep the child from falling off of the seat. The foldable restaurant and public eating area high chair is comprised of the same parts as prior art restaurant and public eating area high chairs, but is built in such a way so that it can fold flat. Folding flat makes the restaurant and public eating area high chair easy to carry, easy to store, and safer to use than prior art restaurant and public eating area high chairs.

The display screen assembly, comprising a display screen, extends laterally from the body and the inner edge of the display screen falls within the lateral extent of the body. The grip portion is also of a minimum size to allow an adult to grip the laryngoscope, the hand abutting the screen assembly.

Abstract: A system, device, and method for binding metadata, such as information derived from the output of a biometric sensor, to hardware intrinsic properties by obtaining authentication-related metadata and combining it with information pertaining to a root of trust, such as a physical unclonable function. The metadata may be derived from a sensor such as a biometric sensor, the root of trust may be a physical unclonable function, the combination of the metadata and root of trust information may employ a hash function, and output from such a hash process may he used as an input to the root of trust. The combined information can he used in interactive or non-interactive authentication.

Abstract: An electrical device includes a memory storing a value indicative the remaining available rated capacity of one or more batteries. The stored value is changed in use to reflect reducing capacity. The initial stored value is chosen so that there is a very high (e.g. >99.9%) confidence that the one or more batteries will provide at least the capacity indicated by the initial stored value. This reduces the chance of failure during emergency procedures. The one or more batteries may be integral to the electrical device. An override facility is provided.

Abstract: Disclosed is a laryngoscope insertion section having a curved superior surface and a curved inferior surface, and a channel extending from the proximal end the channel having an inferior internal surface with a greater curvature than the curvature of the inferior surface. The insertion section is compatible with laryngoscope hardware optimised for indirect viewing, yet enables direct viewing. Additionally, the distance between the inferior and superior surfaces is at a maximum within the intermediate portion, and enables the dimensions of the proximal and distal portions to be minimized. Thus, the intermediate portion, which is located in the patient's oral cavity in use, is provided with greatest depth and therefore strength where the greatest forces are received, whereas the distal and proximal portions are of reduced dimensions to as to minimize trauma to the patient's airway and mouth areas, respectively, in use.

Abstract: An authenticatable device according to one embodiment includes a reconfigurable physical unclonable function (‘RPUF’) used with one parameter to recover sensitive values (e.g., a secret or a share of a secret) and a different parameter to encode and store values (e.g., challenge-helper pairs) correlated to the sensitive values. In another embodiment, a pair of RPUFs is used instead of a single PUF, with one RPUF used to recover sensitive values and the other RPUF used to encode and store correlated values. In still another embodiment, the desired expiration of values can be enforced by employing redundant RPUFs; when the device is powered on, one (or more than one, but less than all) of the RPUFs is selected and transitioned to a new configuration, invalidating any correlated values previously constructed using the old configuration, and the RPUF that was not reconfigured is used to recover the sensitive value(s) using the remaining correlated value(s).

Abstract: A component of a crawler type machine is hardened by explosive depth hardening. The component is typically a crawler track shoe (10), and the roller path surface (11) of the track shoe and immediate underlying metal portion are pre-hardened by placing explosive charge (15) on the surface of the track shoe (10), and detonating the explosive charge to impart a high force on the surface and underlying metal portion for a short duration. The resultant shock wave causes high-velocity deformation at a high stress level, which leads to intensive development of plastic displacement at microscopic size. This increases the hardness and the strength of the surface and underlying metal portion. The surface (11) may be hardened by repetitive explosive depth hardening. Grooves (20) may also be formed in the roller path (11) to accommodate any flow of material.
