Abstract: An intraoral device (1) with a pair of dental aligners (10), each aligner having an outer shell (100) of rigid plastic in the shape of a rounded V defining branches joined at the front part (10a) of the outer shell. The front part has a truncated part in the form of an elongate notch (104), which confers flexibility on the outer shell in a plane orthogonal to the median sagittal plane of the aligners by bringing together or spacing apart the branches of the V. The outer shell includes an impression (106) formed in the front part on the outer face of the outer shell and extending on either side of the elongate notch. The notch cooperates with an attached wedge (50) which serves as a mechanical abutment for blocking flexion of the outer shell at a given curvature when the attached wedge (50) is fixed in the impression (106).

Abstract: A vehicle sliding door brake assembly configured for attachment to a sliding door mechanism of a vehicle may include a brake member connectable to the sliding door mechanism and configured to rotate about a pivot point, the brake member comprising one or more brake portions for selectively engaging a track of the vehicle so as to provide a braking force. The brake portions may be configured to form an inertial counterweight that urges the brake member to move from a neutral position in which the brake portions are not engaged with the track to an engaged position in which one or more of the brake portions are engaged with the track when a sliding door of the vehicle is subjected to an acceleration exceeding a threshold.

Abstract: Methods and apparatus are provided for choosing an energy-efficient coolant temperature for electronics by considering the temperature dependence of the electronics' power dissipation. This dependence is explicitly considered in selecting the coolant temperature T0 that is sent to the equipment. To minimize power consumption PTotal for the entire system, where PTotal=P0+PCool is the sum of the electronic equipment's power consumption P0 plus the cooling equipment's power consumption PCool, PTotal is obtained experimentally, by measuring P0 and PCool, as a function of three parameters: coolant temperature T0; weather-related temperature T3 that affects the performance of free-cooling equipment; and computational state C of the electronic equipment, which affects the temperature dependence of its power consumption. This experiment provides, for each possible combination of T3 and C, the value T0* of T0 that minimizes PTotal.

Abstract: A rack mount assembly measurement tool, for determining physical values including air flow and heat loads, includes a front assembly and a rear duct assembly that are non-intrusively and releasably mounted on the front and rear of such rack mount enclosure. Physical values are sensed at multiple vertical locations to enable a determination of overall and localized heat loads within the enclosure. Front sensor values are collected and wirelessly transmitted from the front assembly to a receiver/processor supported on the rear duct, which generates computed values that are displayed in addition to the sensed values.

An analysis tool based on restricted coupled-line topologies, simple two-dimensional to three-dimensional RLC matrix conversion, and use of prestored synthesized circuits that accurately capture frequency-dependent loss effects. The CAD tool can handle frequency-dependent resistive and inductive effects for coupled-interconnections on large microprocessor chips with >10K of critical nets. This is done in an interactive manner during the design cycle and allows first path fast product design.
