摘要:
The invention herein generally relates to non-destructive, high order harmonic ion motion image current detection. In certain embodiments, ion motion corresponding to high order harmonic frequencies, instead of the secular frequencies, is detected using image current detection with a constant excitation applied to the waveform signal.

A clamp for preventing theft of a motor cycle, by disabling operation of a handlebar brake lever comprises: a pair of jaws connected together at a pivot so as to be movable between an open and a closed condition, the jaws providing when in the closed condition, first and second substantially parallel apertures and through the clamp, the first aperture being shaped to receive a handlebar handgrip portion therethrough, and the second aperture being formed in a movable member and positioned so as to receive a brake or clutch lever operably mounted on the handlebar. The clamp also has a locking device for enabling the jaws to be locked in the closed condition. The movable member is locked at optional positions when the jaws are in the closed condition, by a pair of ribs which engage into a series of transverse grooves formed in the jaw along the length thereof.

A substrate (300) for an RF device includes a plurality of layers (102) of dielectric material cofired in a stack. The plurality of layers (102) is formed from a material having a permittivity. Selected ones of the layers (102) have a pattern of perforations (106) formed in at least one perforated area (104). The perforated areas (104) are generally aligned with one another in the stack to lower one or more of an effective value of a permittivity and a loss tangent in a least one spatially defined region (504) of the substrate (300).
摘要:
A system for monitoring the level of a fluid in a vehicle is provided. The system comprises a capacitance sensor configured to be at least partially immersed in the fluid. The capacitance sensor is configured to measure a first capacitance associated with a predetermined level of the fluid and a second capacitance associated with an actual level of the fluid in the vehicle. The system further comprises a processing circuit configured to determine the actual level of the fluid in the vehicle using the first capacitance and the second capacitance. The processing circuit is configured to receive at least one of an attitude of the vehicle and a temperature of the fluid from at least one sensor coupled to the vehicle. The processing circuit is further configured to compare the determined actual level of the fluid with a threshold level associated with the at least one of the attitude and temperature to identify a relative position of the determined actual level of the fluid with respect to the threshold level.
