  • Publication number: 20150142343
    Abstract: Embodiments of the invention provide systems and methods for tracking the thermal age of a self-regulating heating cable. Over a time period, current and voltage data for a cable signal are collected, from which spectral information is extracted. The spectral information has a frequency component and an amplitude component. The cable signal is processed to extract a line frequency signature that includes the electrical system's line current frequency and at least some of its harmonics. A ratio of the amplitudes of at least two of the odd harmonics of the line current frequency is calculated. The ratio is compared to an aging curve indicating the thermal age of the cable as a function of the odd-harmonic ratios. The curve may be obtained in a laboratory setting or in the field by characterizing a cable with zero hours of use. The characterizing may include aging the cable to determine the curve.

  • Patent number: 8909489
    Abstract: A first detection unit has first and second detection circuits. A second detection unit has third and fourth detection circuits. Output signals of the second and fourth detection circuits differ from output signals of the first and third detection circuits in phase, respectively, by an odd number of times ¼ the signal period. The output signal of the third detection circuit differs from the output signal of the first detection circuit in phase by an integer multiple of ? the signal period other than an integer multiple of ½ the signal period. A rotating field sensor generates a first signal based on the output signals of the first and third detection circuits, generates a second signal based on the output signals of the second and fourth detection circuits, and calculates a detected angle value based on the first and second signals.

  • Patent number: 8898496
    Abstract: In an embodiment, a computing system causes a computing device to operate in a lower-power state. Data received from a first tier of low-power input source(s) is used to determine user/environmental context and activate a second tier of input source(s) that operate in a higher power range. In each tier the system is running contextual detection to assess whether to engage higher power input sources or sensors to aid the user. With this mechanism, a user is able to have access to a broad range of services without having to explicit switch them on, while the system is able to intelligently manage power and battery life across input sources.

  • Patent number: 8886485
    Abstract: Some embodiments of the present invention provide a system that determines whether a cooling device in a computer system is responsive to control signals. During operation of the computer system, a control signal is sent to the cooling device. Next, a response of the computer system to the control signal is measured, wherein the response includes a temperature profile. The frequency content of the control signal is then compared to the frequency content of the temperature profile to determine whether the cooling device is responsive to the control signal.

  • Patent number: 8870454
    Abstract: During operation of the device, a drive circuit may provide a drive signal having a fundamental frequency to two electrothermal filters (ETFs) having different temperature-dependent time constants. In response to the drive signal, the two ETFs may provide signals having the fundamental frequency and phases relative to the drive signal corresponding, respectively, to the time constants of the ETFs. Then, phase-shift values of the phases may be measured using a phase detector, and a signal may be output based on the phase-shift values. Note that the signal may correspond to a value that is a function of a temperature of the device.
