摘要:
Methods and systems are disclosed for an integrated voltage regulator with open loop digital control for power stepping. In one aspect, a method for regulating an output voltage includes receiving data indicative of a power setting associated with an identified state of an electrical circuit, the power setting based on a load current demand of the electrical circuit in the identified state, enabling one or more parallel driver segments based on the received data indicative of the power setting. The method further includes sourcing by the enabled one or more parallel driver segments sufficient current to meet the load current demand of the electrical circuit in the identified state while maintaining the output voltage at a predetermined voltage level, and providing the output voltage to the electrical circuit at the predetermined voltage level.
摘要:
Target land area is three-dimensionally located using an optical sensor and a radar sensor in satellites. The positions of the satellites are measured and images are captured when the sensors point toward land areas. The aiming direction of the optical sensor for each area is measured. The distance between each area and the radar sensor pointing thereto is measured. Images of land areas captured by the sensors and covering common areas are matched. The distance between the target area selected from the common areas and the optical sensor is accurately determined on the basis of the positions of the sensors, the distance between the target area and the radar sensor, and the aiming direction of the optical sensor, which are associated with the images covering the target area.
摘要:
An integrated circuit device comprises a processor and a secure protection zone with security properties that can be verified by a remote device communicating with the integrated circuit device. The secure protection zone includes a persistent storage that is configured for storing cryptographic keys and data. The secure protection zone also includes instructions that are configured for causing the processor to perform cryptographic operations using the cryptographic keys. In addition, the secure protection zone includes an ephemeral memory that is configured for storing information associated with the cryptographic operations. The instructions are configured for causing the processor to perform the cryptographic operations on the data stored in the persistent storage and the information in the ephemeral memory as part of a secure communication exchange with the remote device.
摘要:
Hand-held apparatus and method for determining relative and/or absolute axial position of a conduit end within a fluid coupling includes application of input ultrasonic energy in the form of transient shear waves and analyzing the reflected energy. Application of the input energy collected at different radial positions about a first axial location is used with wavelet based correlation techniques to better analyze the reflected energy signals. Quality of the abutment between the conduit end and a surface associated with the coupling may also be determined as a separate or combined feature of the axial position determination.

摘要:
A plastic bathing fixture formed substantially or entirely of a laminated composite material comprising a show-surface layer of gel-coat or thermoplastic sheet material which may be non-magnetic; a magnetic or magnetizable layer which may coincide with the show-surface layer or be a subsurface layer; and a non-magnetic structural layer of fiber-reinforced resin material. The magnetic layer materials may be localized or strategically placed, and may comprise a resin with a particulate ferromagnetic filler.
