摘要： A wearable device for alerting a user when a static electrical charge has developed on the user which exceeds a preset limit, prior to an accidental discharge of the static charge. The device includes a first conductive element in close proximity to the user and a second conductive element spaced a further distance from the user than the first conductive element. A high impedance differential amplifier provides a voltage signal proportional to the potential difference existing between the first and second conductive elements. A voltage level discriminator receives the voltage signal from the high impedance differential amplifier and triggers an alarm if the voltage signal exceeds a predetermined limit.

摘要： An electrostatic force microscope for measuring electrostatic force of a sample (40) under test including a detector (10) comprising a cantilever arm (12) having a tip formation (14) at one end and located so that electrostatic force is induced at the tip due to electrostatic charge on the sample under test, an optical system (20) for transforming bending of the cantilever arm due to electrostatic force induced at the tip into an electrical signal containing a frequency component of the electrostatic force induced at the tip, a source (92) for applying bias voltage to the detector, a detector circuit (30) for detecting the frequency component of the electrostatic force induced at the detector tip so that a measurement of electrostatic force on the sample under test can be obtained, and an electrostatic shield operatively associated with the cantilever arm.

摘要： An electric field measuring apparatus can guide, with a predetermined optical path length, pulse light with a short pulse width output from a laser light source to an object to be measured or an electric field sensor without expansion of the pulse width caused by wavelength dispersion, thereby enabling electric field measurement with a high time resolution. A laser luminous flux incident on an input end of an input optical system is divided by a light dividing section into probe light and pumping light. After being transmitted through a light delaying device, the probe light is guided through an articulated light guiding path of reflecting mirror type in which a plurality of tubular light guiding sections, each of which has a light guiding path therewithin made of a medium having no wavelength dispersion with a bending point at which a reflecting mirror is disposed, are rotatably cascaded to each other such that their light guiding paths coincide with each other by way of joint sections, so as to be supplied to a microscope unit. On the other hand, the pumping light is guided through an articulated probe light guiding path of reflecting . mirror type so as to irradiate an object to be measured. Also, a CCD camera is united with the exit end of an articulated reflecting mirror type light guiding path, allowing the positioning of the point irradiated with the pumping light.

摘要： Sensor systems and methods for detecting the position and/or movement of an object (20) in multiple degrees of freedom. The sensor system of the present invention comprises at least one field-effect transistor (FET) (110), the geometrical configuration of the FET (110) being selected so as to provide the desired sensitivity. The FET (110) is preferably provided with a conductive gate (140) adjacent to but insulated from the channel region (136) of the FET. An object (20) whose position and/or movement is to be detected is prepared such that an electric field (14) emanates from the object. The FET (110) is brought into the vicinity of the object (20), and the electric field (14) emanating from the object (20) interacts with the gate (140) and/or channel region (136) of the FET (110) so as to modify the magnitude of the electrical current flowing through the channel region (136). The current through the channel region (136) is detected and is used to obtain information about the position and movement of the object (20) relative to the channel region (136) of the FET (110). By positioning a plurality of substantially coplanar FETs in the vicinity of the object, the position and/or movement of the object in any desired number of degrees of freedom can be detected and monitored.
