    • The present invention provides an apparatus and method for nucleotide or DNA sequencing by monitoring the molecular charge configuration as the DNA moves through a protein that is capable of transcribing the DNA. The apparatus and method provides a nanoscale electrometer that immobilizes the protein. The protein receives the DNA and transcribes the DNA. The nanoscale electrometer is a sensitive device that is capable of sensing and measuring the electronic charge that is released during the transcription process. The apparatus and method of the present invention further provides monitoring means that are attached to the nanoscale electrometer to monitor the electronic charge configuration as the DNA moves through the protein. Once the electronic charge configuration is established, a correlation is computed, using computing means, between the electronic charge configuration and a nucleotide signature of the DNA.

    • A system for scanning and measuring a surface charge of a sample immersed in a conductive medium, such as an aqueous electrolytic solution or a gel, or positioned on a conducting plate. The system has a semiconductor with a probing surface clad in a charge-sensitive layer. The probing surface moves over the sample during scanning while a bias voltage V.sub.BIAS is applied to create a depletion layer in the semiconductor and to induce the system to alter a measurable electrical property. The electrical property is monitored with the aid of a measuring device and the measurement is correlated to the sample's surface charge. In a preferred embodiment the semiconductor is a part of a cantilever structure of the type having a probing tip and the probing surface is located on the apex of the probing tip thereby enabling examination of the topology and surface charge of the sample concurrently.

    • This microscope apparatus comprises two probes. The first probe is configured to interact with and measure characteristics of surfaces within an effective measurement distance of the first probe. This probe could be contact type, non-contact type, constant force mode, or constant height mode. A combination of actuation devices positions the first probe over a surface of a sample. The surface is scanned at high speeds in search of a target area. When a target area is found, a scanner moves the sample so that a second contact type probe with a sharp tip is positioned over the target area. The second probe is activated and the target area is scanned at low speeds and high resolution. The first and second probes are part of the same probe assembly. The probe assembly of the present invention does not require probe replacement as frequently as current assemblies because the sharp tip is used only at low speeds and high resolution configurations. Thus, the sharp tip wears slower than it would if the sharp tip was used to find the target feature as well.
    • 该显微镜装置包括两个探针。 第一探针被配置为与第一探针的有效测量距离内的表面相互作用并测量表面的特征。 该探头可以是接触式,非接触型,恒力模式或恒定高度模式。 致动装置的组合将第一探针定位在样品的表面上。 高速扫描表面以寻找目标区域。 当找到目标区域时,扫描器移动样本,使得具有尖锐尖端的第二接触型探针位于目标区域上方。 第二个探针被激活,目标区域以低速和高分辨率扫描。 第一和第二探针是相同探针组件的一部分。 本发明的探头组件不需要像现有组件那样频繁地进行探头更换,因为尖端仅在低速和高分辨率配置下使用。 因此,尖锐的尖端磨损比如果尖锐的尖端用于找到目标特征时的磨损更慢。

    • A tire sensor assembly that is embedded in an elastomeric tire at a particular radial depth inwardly from a contact patch of the tire includes a flexible generally pyramid-shaped body and a pair of first strain sensors disposed on first opposed faces of the pyramid-shaped body, the first strain sensors detecting a force in a first direction. In addition, the assembly includes a pair of second strain sensors disposed on second opposed faces of the pyramid-shaped body, the second strain sensors detecting a force in a second direction. Moreover, each face of the first and second opposed faces is non-planar. Preferably, the first and second opposed faces of the pyramid-shaped body are curved and generally symmetrical about an axis extending longitudinally through the apex of the body so as to allow adjustment of the sensitivity of the sensor assembly generally independent of the radial depth. In one example, the first and second opposed faces are concave such that the sensor assembly is more sensitive to a tensile strain and less sensitive to a shear strain.

    • An AFM that combines an AFM Z position actuator and a self-actuated Z position cantilever (both operable in cyclical mode and contact mode), with appropriate nested feedback control circuitry to achieve high-speed imaging and accurate Z position measurements. A preferred embodiment of an AFM for analyzing a surface of a sample in either ambient air or fluid includes a self-actuated cantilever having a Z-positioning element integrated therewith and an oscillator that oscillates the self-actuated cantilever at a frequency generally equal to a resonant frequency of the self-actuated cantilever and at an oscillation amplitude generally equal to a setpoint value. The AFM includes a first feedback circuit nested within a second feedback circuit, wherein the first feedback circuit generates a cantilever control signal in response to vertical displacement of the self-actuated cantilever during a scanning operation, and the second feedback circuit is responsive to the cantilever control signal to generate a position control signal. A Z position actuator is also included within the second feedback circuit and is responsive to the position control signal to position the sample. In operation, preferably, the cantilever control signal alone is indicative of the topography of the sample surface. In a further embodiment, the first feedback circuit includes an active damping circuit for modifying the quality factor (“Q”) of the cantilever resonance to optimize the bandwidth of the cantilever response.
